Tranexamic Acid for Radiation Cystitis: Benefits, Duration and Important Risks

/0 Comments/in , /by

Blood in the urine after pelvic radiotherapy can be frightening. It may appear months or even many years after treatment for prostate, bladder, rectal or gynaecological cancer. One possible cause is radiation cystitis: delayed injury to the bladder lining and its small blood vessels.

Tranexamic acid is sometimes considered when bleeding is troublesome. It can help stabilise blood clots, but it does not repair the radiation injury itself and it is not suitable for every patient. In urinary tract bleeding, preventing a clot from dissolving may reduce bleeding but may also allow a larger clot to obstruct the bladder or ureter. Careful patient selection and medical supervision are therefore essential.

Seek urgent medical attention if you cannot pass urine, are passing large clots, feel faint or breathless, develop fever or flank pain, or the bleeding is heavy or worsening.

What is radiation cystitis?

Radiotherapy can cause progressive damage to the bladder’s small blood vessels. These vessels may become fragile and bleed easily. Patients may experience visible haematuria, urinary frequency, urgency, pain or recurrent clot retention.

Radiation cystitis should not be assumed simply because a patient has previously received radiotherapy. Infection, urinary stones, recurrent or new cancer, kidney disease and medication-related bleeding must also be considered. Assessment may include urine testing and culture, a full blood count, renal function, imaging of the upper urinary tract and cystoscopy. Biopsy is used selectively because irradiated tissue heals poorly.

How does tranexamic acid work?

The body normally breaks down blood clots through a process called fibrinolysis. Tranexamic acid blocks the binding of plasminogen and plasmin to fibrin, slowing this breakdown. It is therefore an antifibrinolytic medicine: it helps a clot remain in place rather than acting as a blood-clotting factor itself.

For radiation cystitis, tranexamic acid is intended to control active bleeding. It does not remove abnormal radiation-induced blood vessels, reverse fibrosis or prevent future bleeding once the medicine is stopped.

How effective is it for radiation cystitis?

The evidence is limited. Tranexamic acid has been used for haematuria from several causes, and a small randomised emergency-department study found that intravenous treatment reduced the amount of bladder irrigation required to clear the urine. However, it did not significantly reduce haemoglobin loss or transfusion requirements. Importantly, this study included mixed causes of haematuria and was not designed specifically for radiation cystitis.

The Canadian Urological Association best-practice report concluded that evidence was insufficient to make a formal recommendation for tranexamic acid in radiation-induced haemorrhagic cystitis. Later narrative reviews have reached a similar conclusion. Intravesical tranexamic acid, placed directly into the bladder, has shown encouraging results in small emergency-department studies of gross haematuria, but evidence specific to radiation cystitis is still inadequate and this remains a specialist, non-standard use.

In practice, tranexamic acid may be considered as a temporary adjunct in selected patients while the cause and severity of bleeding are assessed, or while more definitive treatment is arranged. It should not delay bladder washout, clot evacuation, cystoscopic treatment, hyperbaric oxygen therapy, embolisation or other appropriate care when these are required.

How long can tranexamic acid be used?

There is no well-supported universal duration for radiation cystitis. The Australian product information for oral tranexamic acid describes treatment of haematuria while blood remains macroscopically visible, but radiation cystitis is a recurrent condition and that instruction should not be interpreted as approval for indefinite therapy.

For this indication, treatment is generally best regarded as a short, medically supervised course for an active bleeding episode. The exact dose and duration depend on:

  • whether bleeding is mild, ongoing or causing clot retention;
  • whether the source is the bladder or upper urinary tract;
  • kidney function, because tranexamic acid is largely eliminated in the urine;
  • previous blood clots, cardiovascular risk and pro-thrombotic medicines;
  • anticoagulant or antiplatelet therapy; and
  • the response to treatment and need for definitive therapy.

There is no good evidence supporting continuous long-term tranexamic acid as prophylaxis for recurrent radiation cystitis. If bleeding has not clearly improved within a short course, recurs promptly after treatment, or requires repeated courses, the diagnosis and management plan should be reassessed. Longer or repeated use should occur only under specialist supervision, with renal function and thrombotic risk reviewed.

Patients should not start, extend, repeat or stop prescribed tranexamic acid without discussing it with their treating clinician.

Important side effects

Common or less serious adverse effects may include:

  • nausea, vomiting, diarrhoea or abdominal discomfort;
  • headache, dizziness or fatigue; and
  • muscle or joint discomfort.

Potentially serious adverse effects include:

Blood clots

Deep-vein thrombosis, pulmonary embolism, stroke, heart attack and other arterial or venous thromboses are uncommon but potentially serious. Risk assessment is particularly important in patients with an active or previous clot, known thrombophilia, active malignancy, prolonged immobility or concurrent pro-thrombotic medication.

Urgent assessment is required for new unilateral leg pain or swelling, sudden chest pain, shortness of breath, coughing blood, weakness on one side, difficulty speaking or sudden severe headache.

Clot retention and urinary obstruction

Tranexamic acid may stabilise clots within the urinary tract. This can contribute to painful bladder clot retention. It is particularly concerning when bleeding arises from a kidney or ureter, because a clot may obstruct the ureter and cause flank pain, hydronephrosis or loss of kidney function. Upper-tract haematuria therefore warrants particular caution and specialist assessment.

Kidney impairment

Most tranexamic acid is excreted unchanged through the kidneys. The dose must be reduced when renal function is impaired; accumulation increases the risk of toxicity, including neurological adverse effects. Significant renal impairment may make treatment inappropriate or require a substantially altered regimen.

Seizures

Seizures are a recognised, dose-related risk, reported particularly with high intravenous doses and when the medicine accumulates in renal impairment. A history of seizures requires careful consideration.

Visual disturbance

Rare visual effects, including altered colour vision, have been reported. New visual symptoms require prompt review and usually discontinuation pending medical advice. Ophthalmic monitoring may be considered when prolonged treatment is unavoidable.

Severe allergy

Facial or throat swelling, wheeze, breathing difficulty or a widespread blistering rash requires emergency care.

Who may not be suitable for treatment?

Tranexamic acid may be contraindicated or require particular caution in people with:

  • active thromboembolic disease or a substantial history or risk of thrombosis;
  • significant kidney impairment;
  • upper urinary tract bleeding or suspected ureteric obstruction;
  • a history of seizures;
  • acquired disturbances of colour vision;
  • disseminated intravascular coagulation unless managed by an experienced clinician; or
  • hypersensitivity to tranexamic acid.

Medication review is essential. Anticoagulants and antiplatelet agents can worsen bleeding, but stopping them may cause stroke, pulmonary embolism, heart attack or coronary-stent thrombosis. They should not be stopped merely because haematuria develops without an individual risk assessment involving the prescribing clinician. Likewise, combining tranexamic acid with pro-thrombotic medicines requires caution.

Where does it fit in the management pathway?

Management is guided by severity. Initial care may include resuscitation, correction of significant anaemia or coagulopathy, a large-bore catheter, manual washout and continuous bladder irrigation. Cystoscopy permits clot evacuation, exclusion of tumour and cautery or laser treatment of bleeding areas.

For persistent or recurrent radiation cystitis, options may include intravesical agents, hyperbaric oxygen therapy, selective arterial embolisation and, rarely, urinary diversion or cystectomy. Hyperbaric oxygen is one of the better-studied treatments because it aims to improve tissue oxygenation and new blood-vessel formation rather than merely suppressing an episode of bleeding.

Tranexamic acid may have a role as a bridge or adjunct in a carefully selected patient. Its value must always be balanced against the danger of thrombosis and urinary tract obstruction.

The take-home message

Tranexamic acid can reduce haematuria in some patients, but evidence specifically for radiation cystitis is weak. It is not a cure and should usually be used only for a short, active bleeding episode under medical supervision. There is no established safe or effective duration for continuous long-term use in radiation cystitis. Kidney function, clotting history, the anatomical source of bleeding and concurrent medication must be reviewed before treatment.

Visible haematuria after radiotherapy always deserves proper investigation, particularly if it is recurrent, contains clots or is accompanied by difficulty passing urine.

This article provides general information and does not replace individual medical advice. Tranexamic acid is a prescription medicine in Australia; its use for radiation cystitis must be individualised by the treating clinician.

Prostate Artery Embolisation: Who May Benefit, Important Caveats, and Can It Be Done After Radiotherapy?

/0 Comments/in , /by

Lower urinary tract symptoms: poor flow, hesitancy, incomplete emptying, frequency, urgency and nocturia, are common as men age. When benign enlargement of the prostate (BPH) is genuinely responsible, treatment may include lifestyle measures, medication, minimally invasive procedures or surgery. Prostate artery embolisation (PAE) is one option that may be considered for appropriately assessed patients.

PAE is not simply a “smaller TURP”. It works differently, is performed by an experienced interventional radiologist, and has a different balance of benefits, limitations and risks. The most important question is not whether the prostate looks large, but whether prostatic obstruction is actually causing the patient’s symptoms.

What is prostate artery embolisation?

PAE is a minimally invasive, image-guided procedure. A small catheter is introduced through an artery, usually at the wrist or groin, and guided into the arteries supplying the prostate. Tiny permanent particles or, in selected expert practice, a liquid embolic agent are delivered to reduce blood flow to the hyperplastic prostate tissue. This causes controlled ischaemia, gradual shrinkage of the transition zone and reduced compression of the urethra.

The procedure can often be performed without a general anaesthetic and does not require instruments to pass through the urethra. Improvement, when it occurs, is usually progressive rather than immediate and may take several weeks or months. Results vary, and some men obtain little benefit or require another treatment.

Regulatory note for Australian readers: The TGA regulates therapeutic goods, including medicines and medical devices; it does not “approve” or endorse a medical procedure or an individual health service. References to PAE in this article should not be interpreted as TGA endorsement. Any embolic agent, catheter or other medical device used must be lawfully supplied in Australia and used in accordance with its applicable regulatory status, intended purpose and clinical governance requirements.

Important Wesley Hospital research

Associate Professor Nicholas Brown, an interventional radiologist affiliated with The University of Queensland and I-MED Radiology at The Wesley Hospital, led the following Australian studies of PAE.

The P-EASY ADVANCE randomised controlled trial, published in BJU International in 2024, compared PAE with combined tamsulosin and dutasteride therapy in 39 treatment-naïve men with enlarged prostates, moderate-to-severe symptoms and obstructed or equivocal urodynamic studies. At follow-up, 63% of men treated with PAE were urodynamically unobstructed, compared with 28% receiving medication. Within this study population and follow-up period, the PAE group had greater improvements in prostate volume, urinary flow, incomplete emptying, overall symptom score and quality of life. The trial was small, the estimates should not be generalised to every patient, and larger comparative trials with longer follow-up are required.

The follow-up P-EASY PLUS study, published in BJU International in 2025, assessed 105 men at a mean of 18 months. Mean prostate volume fell by 30.6%, total symptom scores improved by 55%, quality-of-life scores improved by 65.9%, and maximum urinary flow increased by 5 mL/second. Among the 57 men who completed paired urodynamic testing, the proportion classified as obstructed fell from 66.7% to 29.8%. No major procedural complication or new urinary incontinence was reported in this cohort; new retrograde ejaculation occurred in 2%. These are group-level study outcomes and do not guarantee an individual result. The authors noted that longer-term comparative research is required.

The P-EASY ADVANCE publication received the BJUI Global Prize for 2026. This statement describes the publication award only; it is not a patient-outcome claim, regulatory endorsement or guarantee of treatment effectiveness.

Author disclosure: I, Dr Joseph Schoeman, was a co-author of both Wesley Hospital studies. I performed some of the urodynamic studies for this article. Readers should take this relationship into account when considering the discussion. The results are reported with their limitations and placed alongside independent guidelines, randomised trials and systematic reviews. No patient testimonial or individual outcome has been used in this article.

Who may be a good candidate?

PAE may be considered when a man has:

  • bothersome moderate-to-severe urinary symptoms attributable to benign prostatic obstruction;
  • an enlarged prostate, particularly a moderately large or very large gland;
  • inadequate relief, unacceptable adverse effects or a preference not to take long-term medication;
  • a wish to avoid transurethral or more invasive surgery;
  • increased anaesthetic or surgical risk;
  • a preference for an option with lower reported rates of ejaculatory dysfunction or urinary incontinence in some studies, while recognising that these complications can still occur;
  • catheter-dependent urinary retention where obstruction from BPH is considered reversible and bladder contractility is adequate; or
  • recurrent or refractory bleeding shown to arise from the prostate in selected circumstances.

Current European Association of Urology guidance recommends offering PAE to men with moderate-to-severe LUTS due to benign prostatic obstruction who want a minimally invasive option and accept that outcomes may be less optimal than TURP. The American Urological Association also permits PAE as a treatment option when performed by appropriately trained clinicians, but grades the evidence as conditional.

What assessment is needed before PAE?

A large prostate does not prove obstruction, and urinary symptoms are not always caused by the prostate. Appropriate assessment may include:

  • symptom and quality-of-life scoring;
  • urinalysis and urine culture when indicated;
  • PSA assessment and prostate-cancer evaluation appropriate to age and risk;
  • digital rectal examination;
  • urinary flow rate and post-void residual measurement;
  • ultrasound or MRI assessment of prostate size and anatomy;
  • cystoscopy where haematuria, urethral stricture, bladder-neck pathology, stones or bladder disease is suspected;
  • urodynamic studies when the diagnosis is uncertain, symptoms are mixed, bladder contractility may be poor, or prior pelvic treatment has complicated the picture; and
  • CT or MR angiographic assessment of pelvic arterial anatomy, renal function and contrast risk when requested by the interventional radiologist.

The best decisions are generally made jointly by a urologist and an experienced PAE interventional radiologist.

Potential advantages of PAE

Potential advantages include:

  • no prostate tissue resection and usually no general anaesthetic;
  • day-stay or short hospital admission in many patients;
  • lower reported rates of major bleeding and transfusion than some operative procedures in comparative studies;
  • low reported, but not zero, rates of urinary incontinence;
  • a lower reported likelihood of retrograde ejaculation than with TURP or enucleation procedures in available studies;
  • usefulness in some very large prostates and medically complex patients; and
  • preservation of later surgical options if symptoms persist or recur.

Caveats: what PAE may not do as well

Compared with TURP or endoscopic enucleation, PAE generally produces a less immediate and less pronounced improvement in urinary flow and objective relief of obstruction. A Cochrane review found that short-term symptom improvement may be similar to TURP, but the certainty of evidence was low and retreatment may be more likely after PAE. Meta-analyses and longer-term randomised data generally show stronger objective improvement after TURP. Comparisons across studies must be interpreted cautiously because patient selection, technique, follow-up and outcome definitions differ.

PAE also does not provide prostate tissue for histology. Prostate cancer must therefore be considered and investigated before treatment rather than assumed to be excluded by a fall in prostate size or PSA afterward.

Technical success depends heavily on operator experience. Prostatic arteries are tiny, variable and sometimes severely atherosclerotic. Embolic material can rarely reach non-target vessels supplying the bladder, rectum or penis. Pre-procedure vascular imaging and cone-beam CT can reduce this risk but add iodinated contrast exposure and ionising radiation.

Side effects and complications

Common short-term effects form part of a post-embolisation syndrome and may include pelvic or perineal discomfort, urinary frequency and urgency, dysuria, fatigue, nausea, low-grade fever or a small amount of blood in the urine or semen. Temporary difficulty passing urine and the need for a catheter can occur.

Less common complications include urinary infection, access-site bruising or haematoma, contrast reaction, kidney injury, arterial injury, prostate infection or abscess, and passage of necrotic prostate tissue. Rare but important complications of non-target embolisation include ischaemic injury to the bladder, rectum or penis. Severe skin injury from fluoroscopic radiation is also rare but is a recognised procedural concern, particularly during prolonged or technically difficult cases.

Contraindications and reasons to pause

PAE is generally unsuitable, or requires correction and specialist review first, when there is:

  • an active urinary tract or systemic infection;
  • suspected or untreated prostate or bladder cancer requiring diagnostic clarification;
  • symptoms predominantly caused by urethral stricture, bladder-neck contracture, bladder stone, neurogenic dysfunction, overactive bladder or another non-BPH condition;
  • a poorly contractile or decompensated bladder unlikely to empty even if outlet resistance is reduced;
  • severe pelvic arterial atherosclerosis, occlusion, tortuosity or anatomy that prevents safe selective catheterisation;
  • an uncorrectable bleeding disorder;
  • a severe iodinated-contrast allergy that cannot be safely managed;
  • significant renal impairment where contrast risk is unacceptable; or
  • inability to tolerate arterial access, fluoroscopy or the required aftercare.

Small prostate size is not an absolute prohibition, but it makes careful confirmation of the cause of obstruction particularly important and may reduce the likelihood of benefit. A prominent obstructing median lobe is not automatically a contraindication in experienced hands, although prostate anatomy should be considered alongside all alternative treatments.

Can PAE be performed after prostate radiotherapy?

Potentially yes, but prior pelvic or prostate radiotherapy is not a routine indication, and the decision must be individualised. It is neither sensible to call radiotherapy an automatic absolute contraindication nor appropriate to assume that PAE will relieve every post-radiation urinary symptom.

After radiotherapy, poor flow, urgency, frequency, pain, retention or bleeding may result from:

  • persistent benign prostatic obstruction;
  • radiation cystitis and reduced bladder capacity;
  • detrusor overactivity or poor bladder contractility;
  • urethral stricture or bladder-neck stenosis;
  • prostate-cancer recurrence or progression;
  • infection, stones or clot retention; or
  • a combination of these problems.

PAE is most likely to help only when a meaningful component of the problem is supplied by vascular, enlarged prostate tissue or confirmed prostatic obstruction. It will not correct a urethral stricture, a scarred bladder neck, radiation cystitis, a small fibrotic low-capacity bladder or detrusor failure.

Evidence specifically studying PAE for BPH-type obstruction after completed radiotherapy is sparse. Most major BPH trials did not establish a dedicated post-radiotherapy evidence base. Radiotherapy can also alter pelvic tissues and small blood vessels, making angiographic anatomy and tissue response less predictable. For that reason, these patients should be assessed in a multidisciplinary setting and often benefit from cystoscopy, flow and residual testing, imaging and formal urodynamics before treatment.

PAE has been studied in men with prostate cancer and is being investigated before radiotherapy to reduce gland size and urinary symptoms. Embolisation has also been used for refractory bleeding of prostatic origin, including bleeding associated with malignancy or radiation. However, embolisation for life-threatening radiation-related haematuria may target vesical or other pelvic arteries and is a different clinical problem from PAE for benign outlet obstruction. These two indications should not be confused.

In a post-radiotherapy patient, PAE may therefore be reasonable when:

  1. recurrent cancer, infection and urethral or bladder-neck stenosis have been excluded or appropriately managed;
  2. investigations demonstrate an enlarged, vascular prostate with genuine outlet obstruction;
  3. bladder function is adequate enough to benefit from reducing resistance;
  4. pelvic arterial anatomy permits safe selective embolisation; and
  5. the patient understands that outcome data are limited and that further treatment may still be required.

How does PAE compare with surgery?

There is no universally “best” procedure. TURP, GreenLight laser, HoLEP or other enucleation procedures usually provide faster and more complete mechanical relief of obstruction. PAE is less invasive and some comparative studies report fewer ejaculatory or perioperative adverse effects; however, symptom relief can be slower, objective improvement may be smaller and retreatment may be more likely.

The right option depends on prostate size and configuration, the severity and cause of symptoms, bladder function, cancer risk, medical fitness, sexual priorities, arterial anatomy, previous pelvic treatment and the patient’s tolerance for the possibility of later retreatment.

The take-home message

PAE is an available treatment option for selected men with symptomatic benign prostatic obstruction. The Wesley Hospital P-EASY studies contribute Australian randomised and urodynamic data on symptoms, quality of life and obstruction, but their findings should be considered with the study designs, sample sizes, follow-up and declared author relationships.

It remains essential to diagnose the cause of symptoms before treating the scan. PAE is not a cure for every urinary problem and does not replace cancer assessment, cystoscopy or urodynamics when these are clinically indicated. After radiotherapy, PAE may be technically and clinically possible, but the evidence is limited and patient selection must be particularly rigorous.

Blood in the Urine After Radiotherapy: Understanding Radiation Cystitis

/0 Comments/in , /by

Pelvic radiotherapy is an important and often highly effective treatment for prostate, bladder, rectal and gynaecological cancers. However, radiation can leave the small blood vessels and lining of the bladder fragile. Months or even many years later, this may cause urinary symptoms or bleeding known as radiation cystitis. When bleeding is prominent, the condition is also called radiation-induced haemorrhagic cystitis.

Most episodes can be controlled, but visible blood in the urine must never simply be attributed to previous radiotherapy. Infection, urinary stones, recurrent cancer and a new bladder or upper urinary tract cancer must first be considered.

Seek urgent medical care if you cannot pass urine, are passing large clots, feel faint or short of breath, develop fever or severe pain, or have heavy ongoing bleeding.

What causes radiation cystitis?

Radiotherapy damages cancer cells, but the bladder may receive some radiation because it lies close to the treatment area. Early inflammation can make the bladder lining swollen and irritable. Late injury is different: progressive damage to small blood vessels causes reduced oxygen supply, scarring and fragile abnormal vessels called telangiectasia. These vessels may bleed with little provocation.

Radiation damage can also reduce bladder capacity and elasticity. In severe cases, ulceration, fibrosis, fistula formation or obstruction may occur.

When does it present?

Radiation-related bladder problems have two broad patterns:

  • Acute radiation cystitis occurs during radiotherapy or within the first few weeks or months. Frequency, urgency, burning and pelvic discomfort are common; substantial bleeding is less usual. Symptoms often settle after treatment finishes.
  • Late radiation cystitis generally begins more than six months after radiotherapy and may appear years or even decades later. The Canadian Urological Association review notes pathological vascular changes from about 6–12 months, with new symptoms reported as long as 20 years after treatment.

The risk varies with radiation dose and field, treatment technique, previous pelvic surgery, smoking, vascular disease, diabetes and combined cancer treatments.

How can it present?

Presentation ranges from microscopic blood found on a urine test to recurrent heavy bleeding with clots. Symptoms may include:

  • pink, red or cola-coloured urine;
  • small or large blood clots;
  • urinary frequency, urgency, burning or bladder pain;
  • interrupted flow or complete retention when clots obstruct the outlet;
  • tiredness, dizziness or breathlessness from anaemia; and
  • a small, painful or poorly compliant bladder in advanced disease.

Bleeding may be intermittent. A clear urine sample between episodes does not exclude radiation cystitis.

Does anticoagulant or antiplatelet therapy matter?

Anticoagulants such as warfarin, apixaban, rivaroxaban or dabigatran, and antiplatelet drugs such as aspirin or clopidogrel, do not create radiation cystitis. They can, however, make bleeding from its fragile vessels more prolonged or severe. Excess anticoagulation, impaired kidney function, drug interactions and combined anticoagulant–antiplatelet therapy can further increase bleeding risk.

These medicines may be preventing a stroke, heart attack, pulmonary embolus or thrombosis of a coronary stent. Do not stop them yourself. During significant bleeding, the urologist, emergency team and the clinician responsible for the medication should jointly balance:

  • the severity of bleeding and haemoglobin fall;
  • the reason for treatment and the risk of thrombosis if it is interrupted;
  • the last dose, kidney function and, for warfarin, the INR;
  • whether a temporary hold, reversal or dose adjustment is justified; and
  • when and how treatment should safely restart.

Importantly, anticoagulant or antiplatelet use does not remove the need to investigate haematuria. It may reveal bleeding from an otherwise silent bladder or upper-tract tumour.

How is haematuria investigated after radiotherapy?

Assessment is tailored to the patient and severity, but commonly includes:

  1. History and examination: radiation site, dose and timing; cancer history; smoking; infection symptoms; bleeding pattern; and all medicines.
  2. Urine testing: urinalysis and culture. Urine cytology may be appropriate in selected patients, but it does not replace cystoscopy.
  3. Blood tests: full blood count, kidney function and coagulation studies. Severe or ongoing bleeding may require group-and-screen or crossmatch.
  4. Imaging of the upper urinary tracts: usually CT urography when appropriate; ultrasound or alternative imaging may be chosen when contrast or radiation exposure is unsuitable.
  5. Cystoscopy: inspection of the urethra and bladder to identify typical diffuse telangiectasia, exclude a tumour, evacuate clots and sometimes cauterise bleeding vessels. Suspicious areas require biopsy, performed carefully because irradiated tissue heals poorly.

A stepwise approach to treatment

Treatment depends on the rate of bleeding, clot retention, anaemia, bladder function, medical fitness and local expertise. No single treatment suits every patient.

1. Stabilisation and bladder drainage

Heavy bleeding may require hospital admission, intravenous fluids, correction of anaemia or clotting abnormalities, and blood transfusion when clinically necessary. A large three-way catheter permits manual clot washout and continuous bladder irrigation with saline. Persistent clots may require cystoscopic evacuation under anaesthesia.

Treat a proven urinary infection, but antibiotics do not treat sterile radiation injury. Medication contributing to bleeding should be reviewed collaboratively rather than stopped automatically.

2. Cystoscopy and endoscopic haemostasis

Cystoscopy can confirm the diagnosis and exclude malignancy. Focal bleeding may be treated with diathermy, laser or another endoscopic coagulation technique. This is often effective initially, although diffuse disease may recur and repeated aggressive cautery can worsen scarring or perforation risk.

3. Intravesical and systemic options

Options used for persistent or recurrent bleeding include:

  • Alum bladder irrigation: may control bleeding relatively quickly, but recurrence is possible. It requires caution in substantial kidney impairment because aluminium toxicity can occur.
  • Hyaluronic acid, sometimes combined with chondroitin sulphate: aims to restore the bladder’s protective lining. Evidence suggests benefit for haematuria and urinary symptoms, but treatment is gradual and is not suitable for an unstable major bleed.
  • Oral sodium pentosan polysulphate: has limited, slower-onset evidence. Long-term exposure also requires discussion of pigmentary maculopathy and eye monitoring.
  • Other agents have been reported, but supporting evidence is generally limited.

Formalin can rapidly seal bleeding vessels but may cause severe pain, bladder contraction, reflux, ureteric damage, fistula or systemic complications. It is therefore reserved for life-threatening or otherwise uncontrollable bleeding, used at the lowest effective concentration by experienced teams after the upper tracts have been assessed and protected.

4. Hyperbaric oxygen therapy

Hyperbaric oxygen therapy (HBOT) is one of the best-studied treatments for persistent late radiation cystitis. The patient breathes 100% oxygen in a pressurised chamber. This increases tissue oxygen levels and encourages new blood-vessel growth and healing in chronically oxygen-deprived bladder tissue; it is not simply a short-lived attempt to “oxygenate the blood.”

How effective is it?

The evidence is encouraging, although success definitions and patient populations vary:

  • A meta-analysis cited by the Canadian Urological Association included 602 patients with at least one year of follow-up; 84% achieved partial or complete resolution of haematuria.
  • The multicentre randomised RICH-ART trial found a clinically meaningful improvement in patient-reported urinary symptoms after HBOT compared with standard care. At five years, 48 of 70 followed patients (68.6%) met the study’s responder definition, and the mean improvement among responders remained substantial. This supports durability for many—but not all—patients.
  • HBOT is not guaranteed. Some patients have incomplete improvement, relapse, or still require endoscopic or more invasive treatment. Earlier referral after recurrent bleeding may be preferable to waiting until the bladder is severely fibrotic or the patient has needed repeated transfusions.

How long does it take?

A usual course is 30–40 weekday sessions, sometimes more. Each treatment commonly involves approximately 80–90 minutes breathing oxygen at pressure, although total chamber time is longer. In practical terms, treatment usually takes six to eight weeks. Benefit may develop during the course and continue over subsequent weeks or months as tissue healing progresses.

HBOT is unsuitable or requires specialist assessment in some circumstances. An untreated pneumothorax is an absolute contraindication. Ear or sinus pressure injury, temporary visual change, claustrophobia and, rarely, oxygen-related seizure can occur. Lung disease, certain chemotherapy drugs, implanted devices and difficulty equalising ear pressure require individual review. Availability and daily travel are practical limitations.

5. Arterial embolisation

For ongoing significant bleeding despite less invasive measures, selective or super-selective embolisation can block the bleeding arterial supply. Modern targeted techniques reduce, but do not eliminate, risks such as pelvic pain, tissue ischaemia and non-target embolisation. It can be valuable in frail patients who are poor candidates for major surgery.

When should urinary diversion be considered?

Urinary diversion is a last-resort, potentially life-saving strategy, not an early treatment for uncomplicated bleeding. It should be discussed in a multidisciplinary setting at an experienced centre when there is:

  • life-threatening, transfusion-dependent or recurrent clotting haematuria despite endoscopic treatment, HBOT, appropriate intravesical therapy and/or embolisation;
  • a severely contracted, painful, non-functional bladder with intolerable frequency or poor storage;
  • fistula, necrosis, major outlet or ureteric damage, or progressive upper-tract deterioration;
  • repeated admissions and unacceptable loss of quality of life; or
  • inability to control bleeding safely by less invasive means.

Options include nephrostomy tubes or ureteric occlusion as temporary or palliative measures; cutaneous ureterostomy; or an ileal conduit. Diversion without removing the bladder may be considered in a very high-risk patient, but the retained irradiated bladder can continue to bleed, become infected or painful, and may later require surgery. Cystectomy with diversion provides definitive removal of the diseased bladder but is a major operation. Previous radiation makes tissue planes, healing and bowel surgery more difficult, so complication and mortality rates are substantially higher than for routine cystectomy.

The decision should incorporate the patient’s cancer status, cardiovascular and respiratory fitness, frailty, kidney and bowel function, previous operations, goals of care and willingness to manage a stoma or external drainage.

The practical message

Radiation cystitis may appear long after the original cancer treatment and can range from mild intermittent haematuria to a medical emergency. Blood-thinning medication may worsen the episode, but it should neither be blamed as the sole cause nor stopped without a coordinated medical plan. A careful evaluation to exclude malignancy and other treatable causes comes first.

Management is progressive: stabilisation and irrigation, cystoscopic treatment, selected bladder therapies, HBOT and embolisation before major diversion surgery. HBOT offers worthwhile, durable improvement for many appropriately selected patients, but requires a substantial weekday treatment commitment. Diversion is reserved for a devastated bladder or bleeding that remains dangerous despite comprehensive treatment.

Urinary Incontinence After Prostatectomy and Salvage Radiotherapy

/0 Comments/in , , /by

Why leakage may become more complex after both treatments

Urinary leakage after radical prostatectomy is common in the early recovery period and usually improves with healing and pelvic floor rehabilitation. Some men, however, require salvage radiotherapy because their PSA remains detectable or rises after surgery.

Radiotherapy can help control recurrent prostate cancer, but it may also affect tissues that have already been altered by surgery. Radiation can cause progressive scarring, reduced blood supply and loss of elasticity in the urethra, bladder neck and bladder. These effects may develop months or even years later.

As a result, leakage after prostatectomy and salvage radiotherapy is not always caused by a weak urinary sphincter alone. A man may have:

  • Stress urinary incontinence: leakage with coughing, standing, lifting, walking or exercise because the sphincter does not close effectively.
  • Urgency urinary incontinence: leakage accompanied by a sudden, difficult-to-defer urge, often caused by an overactive or irritated bladder.
  • Overflow leakage: leakage associated with poor bladder emptying, a weak bladder muscle or obstruction.
  • Mixed incontinence: a combination of stress and urgency leakage.
  • Radiation-related complications: bladder-neck contracture, urethral stricture, radiation cystitis, poor bladder compliance, fistula, tissue necrosis or, in severe cases, a severely damaged bladder outlet.

Correctly identifying the cause is essential. Tightening the outlet when the bladder cannot store or empty safely may replace one problem with another.

When should the problem be assessed?

Continence can continue to improve during the first year after prostatectomy. Pelvic floor muscle training should begin early, and surgical treatment may be considered as early as six months when severe leakage is clearly not improving. Persistent, bothersome stress incontinence at approximately 12 months deserves formal assessment.

Following salvage radiotherapy, earlier review is appropriate if there is:

  • worsening leakage;
  • blood in the urine;
  • recurrent urinary infection;
  • pain, burning or severe urgency;
  • a weak stream or difficulty emptying;
  • urinary retention;
  • pelvic or perineal pain; or
  • urine leaking through an abnormal opening.

Visible haematuria, fever, inability to pass urine or severe pain requires prompt medical attention.

Investigating incontinence after salvage radiotherapy

1. A careful history

The first step is to establish what type of leakage is occurring, when it began and whether it changed after radiotherapy. Important questions include:

  • Is leakage triggered by activity, or by urgency?
  • How many pads are used, and how wet are they?
  • Is the patient dry at night or when lying down?
  • Is there a weak stream, straining or incomplete emptying?
  • Are there recurrent infections, haematuria or pelvic pain?
  • Were there previous bladder-neck or urethral procedures?
  • How much does leakage affect work, exercise, sleep, intimacy and quality of life?

Manual dexterity and cognition are also important if an artificial urinary sphincter is being considered, because the patient must be able to locate and operate a small scrotal pump.

2. Bladder diary and pad assessment

A three-day bladder diary records fluid intake, voided volumes, urgency and leakage. Pad number gives a useful impression, but pads differ greatly. A 24-hour pad-weight test can quantify the actual volume lost and help grade severity and monitor progress.

3. Examination and basic tests

Assessment commonly includes:

  • abdominal, genital, perineal and neurological examination;
  • observation for leakage while coughing or standing with a comfortably full bladder;
  • urinalysis and urine culture when infection is suspected;
  • uroflowmetry;
  • ultrasound measurement of the post-void residual; and
  • renal function testing or upper-tract imaging when clinically indicated.

4. Cystoscopy

Cystoscopy is particularly important before continence surgery in a previously irradiated urinary tract. It allows the urologist to inspect the urethra, bladder neck and bladder for:

  • urethral stricture or bladder-neck contracture;
  • radiation damage, stones or tumour;
  • erosion from a previous implant;
  • tissue quality and sphincter appearance; and
  • fistula or necrosis in complex cases.

Any clinically important obstruction or unstable urethral disease usually needs to be treated and shown to be stable before an anti-incontinence device is implanted.

What is the role of urodynamic studies?

Urodynamics is not mandatory for every man with straightforward stress leakage. It becomes more useful when symptoms are mixed, the diagnosis is uncertain, previous radiation has made the situation more complex, or the result may change treatment.

The study can assess:

  • stress leakage and sphincter weakness;
  • involuntary bladder contractions;
  • bladder capacity and sensation;
  • reduced bladder compliance or unsafe storage pressures;
  • obstruction;
  • weak bladder contraction; and
  • the ability of the bladder to empty against a future sling or sphincter cuff.

Urodynamics is especially worth considering when there is marked urgency, nocturnal leakage, retention, a raised residual, poor flow, recurrent infection, prior outlet reconstruction or concern about a small, painful or poorly compliant radiation-damaged bladder.

The test does not simply decide whether a man “qualifies” for an operation. Its value is in identifying bladder dysfunction that should be treated first or a bladder that may not tolerate additional outlet resistance.

Initial and non-surgical management

Pelvic floor rehabilitation

Supervised pelvic floor muscle training can improve control and teach correct muscle activation. It is most useful early after prostatectomy but may still improve coping and control later. Repeated forceful exercises are not always better; poor technique can worsen pelvic tension or urgency.

Bladder and lifestyle measures

Management may include weight reduction where relevant, treating constipation, moderating caffeine and alcohol, adjusting the timing of fluids and diuretics, bladder training and treating urinary infection. Antimuscarinic medication or a beta-3 agonist may help an overactive-bladder component, but medication does not restore a damaged sphincter.

Pads, sheaths and clamps

Absorbent pads remain a practical option for mild leakage or while awaiting treatment. A condom drainage sheath can direct urine into a leg bag when penile skin and anatomy permit.

A penile clamp may provide short-term control for selected men with good sensation, intact skin and adequate bladder emptying. It must be released regularly and should not be used overnight. Extra caution is required after radiation because pressure injury may heal poorly.

Catheter options

Catheters manage drainage; they do not repair stress incontinence. They may nevertheless be appropriate when there is retention, very poor emptying, severe frailty, failed reconstruction or a need for temporary urinary control.

Intermittent self-catheterisation

Intermittent self-catheterisation is generally preferred when the bladder fails to empty but the patient has sufficient dexterity and urethral access. It avoids a continuously indwelling tube, although irradiated strictures or a false passage may make catheterisation difficult.

Long-term urethral catheter

An indwelling urethral catheter may be necessary in selected patients, but long-term use can cause infection, discomfort, blockage, bladder stones, urethral erosion and further outlet damage. A catheter passing through an activated AUS cuff can also cause serious urethral erosion; healthcare providers must be told that an AUS is present and the device should be deactivated before urethral instrumentation.

Suprapubic catheter

A suprapubic catheter enters the bladder through the lower abdomen. For long-term drainage it often avoids continuing urethral pressure and may be easier to manage than a urethral catheter. It still requires regular changes and carries risks including infection, blockage, bladder stones, leakage and skin problems.

Male sling versus artificial urinary sphincter

Male sling

A male sling supports and repositions or compresses the urethra. Its advantages include no scrotal pump and no need to operate the device each time the patient urinates. In carefully selected, non-irradiated men with mild-to-moderate stress incontinence, a sling can be effective.

However, previous pelvic radiotherapy is a recognised predictor of poorer sling outcomes. Fibrosis limits urethral mobility and tissue recovery, and moderate-to-severe leakage further reduces success. A sling may still be discussed in a highly selected patient with very mild leakage, good residual sphincter function and a stable, healthy-looking urethra, but expectations must be conservative.

Artificial urinary sphincter (AUS)

The AUS consists of a fluid-filled cuff around the urethra, a pressure-regulating balloon and a pump in the scrotum. The cuff stays closed to control leakage. The patient squeezes the pump to open it temporarily when passing urine.

For men with moderate-to-severe stress incontinence, the AUS remains the most established surgical treatment. Importantly, the AUA/GURS/SUFU guideline recommends offering an AUS rather than a male sling or adjustable balloons to men seeking surgery after primary, adjuvant or salvage radiotherapy.

Radiation does not make AUS implantation impossible, but outcomes are less predictable than in non-irradiated men. Radiation increases the risks of urethral erosion, infection, tissue atrophy, revision and device removal. Mechanical parts also have a limited lifespan, so further surgery may eventually be required.

Practical comparison

Consideration Male sling Artificial urinary sphincter
Best-established role Mild-to-moderate stress leakage in selected men Moderate-to-severe stress leakage
Previous salvage radiotherapy Lower success; generally not preferred Guideline-preferred surgical option, with higher complication risk than in non-irradiated men
Patient operation No pump Scrotal pump must be squeezed for each void
Manual dexterity required Minimal Yes
Retention risk Possible Possible if device is not cycled correctly or obstruction develops
Long-term considerations Persistent leakage or failure may require AUS Mechanical failure, erosion, infection or atrophy may require revision or removal

Neither operation guarantees complete dryness. The choice should consider pad weight, bladder function, urethral health, prior strictures or surgery, dexterity, patient priorities and the reconstructive surgeon’s assessment.

When an AUS or sling is not enough

A small group of men develop a severely scarred, painful or repeatedly obstructed outlet, sometimes called a devastated bladder outlet. This may include recurrent bladder-neck contracture or urethral stricture, fistula, radionecrosis, repeated AUS erosion, severe radiation cystitis or an unsafe low-capacity bladder.

Further implant surgery may then be unlikely to succeed. The priority changes from preserving normal voiding to obtaining dependable drainage, protecting the kidneys and improving quality of life.

Options at a specialist reconstructive centre may include:

  • long-term suprapubic drainage;
  • closure of the bladder neck with a suprapubic catheter in selected cases;
  • a catheterisable abdominal channel in carefully selected patients;
  • an ileal conduit, in which urine drains through a short segment of bowel to a urostomy bag on the abdomen;
  • another form of continent urinary diversion in selected fit patients; or
  • cystectomy with urinary diversion when the bladder is severely painful, contracted, bleeding, fistulating or otherwise unsalvageable.

These are major, irreversible procedures with substantial risks. They should be considered only after detailed imaging and functional assessment, review of cancer status, discussion with an experienced reconstructive team and consultation with a stomal therapy nurse.

A sensible treatment pathway

  1. Define the leakage: stress, urgency, overflow or mixed.
  2. Measure its severity: diary, pads and preferably pad weight.
  3. Check storage and emptying: urine testing, flow and residual; use urodynamics when the findings may alter treatment.
  4. Inspect the outlet: cystoscopy before implant surgery, particularly after radiation.
  5. Treat infection, obstruction and bladder dysfunction first.
  6. Use conservative or catheter strategies when appropriate.
  7. For persistent radiated stress incontinence, discuss AUS as the usual preferred operation.
  8. Reserve sling surgery for exceptional, carefully selected radiated patients after frank counselling.
  9. Refer severe outlet or bladder destruction to a high-volume reconstructive centre to discuss reconstruction versus diversion.

The take-home message

Urinary incontinence after prostatectomy and salvage radiotherapy is treatable, but it needs more than a pad count and a one-size-fits-all operation. The bladder, sphincter and urethra must each be assessed.

For straightforward sphincter weakness after radiation, the artificial urinary sphincter usually offers the most reliable surgical option, although radiation increases the likelihood of erosion and future revision. A male sling is less invasive but is less dependable in irradiated tissue. When the outlet or bladder is severely damaged, catheter drainage, bladder-neck closure or urinary diversion may provide a safer and more durable solution than repeated continence procedures.

This article provides general information and does not replace an individual assessment. Treatment should be tailored to the patient’s symptoms, examination, bladder function, urethral condition, cancer status and personal priorities.

Radical Prostatectomy After Radiation Therapy for Prostate Cancer

/0 Comments/in , /by

When prostate cancer returns after radiotherapy

Radiotherapy, whether external-beam radiation or brachytherapy can provide excellent long-term control of localised prostate cancer. However, a rising prostate-specific antigen (PSA) after treatment may indicate that the cancer has returned.

This does not automatically mean that the cancer is still in the prostate, nor does every PSA rise require immediate treatment. Recurrence may be confined to the prostate, present in lymph nodes or bones, or involve more than one site. Some recurrences also progress slowly enough that surveillance may be appropriate.

When clinically significant cancer is proven to have returned within the irradiated prostate, with no evidence of spread elsewhere, removal of the prostate may still offer a chance of cure. This operation is called a salvage radical prostatectomy.

What is a salvage radical prostatectomy?

A salvage radical prostatectomy removes the entire prostate and seminal vesicles after previous prostate radiotherapy. Depending on the cancer and imaging findings, pelvic lymph nodes may also be removed.

The operation may be performed using robotic-assisted or open surgery. A robotic approach can improve magnification and access, but it does not remove the biological effects of previous radiation. Surgeon and centre experience are therefore more important than the label attached to the surgical technique.

Salvage surgery is technically more difficult than a prostatectomy performed before radiotherapy. Radiation can cause:

  • scarring and fibrosis around the prostate;
  • loss of the normal tissue planes between the prostate, bladder and rectum;
  • reduced tissue blood supply;
  • poorer tissue healing; and
  • pre-existing damage to urinary, erectile or bowel function.

For these reasons, salvage prostatectomy should generally be undertaken in a centre with specific experience in complex prostate cancer surgery and access to multidisciplinary care.

When might salvage surgery be considered?

The aim is to identify a man who has a meaningful risk from his recurrent cancer, but whose disease still appears curable with local treatment. Possible indications include:

  • a rising PSA after radiotherapy, commonly assessed using the Phoenix definition: a PSA rise of at least 2 ng/mL above the lowest PSA reached after treatment;
  • prostate cancer confirmed on biopsy after radiotherapy;
  • imaging suggesting that the recurrence is confined to the prostate or immediate surrounding tissues;
  • no evidence of distant metastatic disease;
  • a life expectancy long enough to benefit from curative treatment, often more than 10 years;
  • good general health and fitness for major surgery;
  • acceptable baseline bladder function; and
  • willingness to accept a higher risk of urinary and sexual side effects than with a primary prostatectomy.

Factors such as the PSA level, PSA doubling time, interval since radiotherapy, biopsy Grade Group, clinical stage and the original cancer characteristics help estimate whether salvage treatment is likely to be worthwhile.

Assessment before considering surgery

A rising PSA is the beginning of the assessment—not the final diagnosis. Investigations commonly include:

Review of the original treatment

The radiation dose and field, use of brachytherapy, previous androgen-deprivation therapy, original biopsy grade and pre-treatment imaging should all be reviewed.

Multiparametric MRI

MRI can help identify the site and extent of a local recurrence, assess the seminal vesicles, bladder neck and rectal interface, and guide biopsy. Interpretation after radiation can be challenging and benefits from specialist radiological expertise.

PSMA PET/CT

PSMA PET/CT is used to look for disease in lymph nodes, bones or other organs. Finding metastatic disease usually changes the treatment plan and may mean that removing the prostate would not provide the expected benefit. Very small-volume disease can still be below the resolution of any scan.

Prostate biopsy

Major guidelines recommend pathological confirmation before potentially morbid local salvage therapy. Biopsy can confirm viable cancer, determine its grade and help distinguish clinically important recurrence from post-radiation change. Both targeted and systematic sampling may be considered.

Urinary-function assessment

Assessment may include symptom scores, urine testing, urinary-flow measurement, residual urine ultrasound and cystoscopy. Urodynamic testing may be helpful when there is significant urgency, leakage, poor flow, retention or uncertainty about bladder function.

Who may not be a good candidate?

Salvage prostatectomy is less likely to be appropriate when:

  • metastatic or extensive nodal disease is present;
  • the cancer is unlikely to be completely removable;
  • life expectancy is limited by age, frailty or other illness;
  • the recurrence is low risk and unlikely to threaten health;
  • severe urinary or bowel damage already exists after radiation; or
  • the anticipated harms of surgery outweigh the probability of cancer control.

These are not absolute rules. Individual circumstances should be reviewed by a multidisciplinary team involving urology, radiation oncology, medical oncology, radiology and pathology.

What are the potential benefits?

For carefully selected men, salvage prostatectomy can:

  • remove the recurrent cancer and provide complete pathological staging;
  • provide durable PSA control without immediately committing the patient to lifelong hormonal therapy; and
  • offer a possibility of cure when disease is truly confined to the prostate.

Published results vary considerably because most evidence comes from retrospective series involving highly selected patients. The European Association of Urology reports five-year biochemical recurrence-free estimates broadly around 41–52% in a large contemporary systematic review, while older selected series have reported ranges of approximately 47–82%. A broader meta-analysis of all local salvage approaches found roughly 50–60% five-year recurrence-free survival, without clear evidence that one approach was oncologically superior. These figures should not be interpreted as a personal prediction.

Cancer control is generally more favourable when the PSA is lower, the recurrent tumour is organ-confined, the cancer grade is lower, the PSA doubling time is longer and there is no nodal or distant disease.

Side effects and complications

Complication rates vary with baseline function, radiation type and dose, disease extent, surgical technique, definitions used in studies and surgeon experience. Results from specialist centres may not apply everywhere.

Urinary incontinence

Loss of urinary control is one of the most important risks. Radiation may already have affected the sphincter, bladder and urethral tissues, and surgery removes the prostate through which the urethra passes.

Leakage may range from mild stress incontinence to severe continuous leakage. Pelvic-floor rehabilitation can help, but some men may later require a male sling or artificial urinary sphincter. Continence outcomes reported in the literature vary widely because studies use different definitions; the risk of significant or persistent leakage is clearly higher than after primary prostatectomy.

Erectile dysfunction

Erectile function is often already impaired by radiotherapy, age, vascular disease or hormonal treatment. Preservation of the erectile nerves may be unsafe or technically impossible because of tumour location and radiation fibrosis. Consequently, erectile dysfunction after salvage prostatectomy is very common and recovery of unassisted erections is uncommon.

Rehabilitation and treatment options include tablets, vacuum devices, penile injections and penile prosthesis surgery. As with any radical prostatectomy, ejaculation and natural fertility are lost because the prostate and seminal vesicles are removed.

Bladder-neck contracture or urethral narrowing

Scar tissue may develop where the bladder is reconnected to the urethra. This can cause a weak stream, straining, incomplete emptying, retention or recurrent infection. Treatment may require endoscopic incision or dilatation, sometimes more than once. Repeated procedures can worsen incontinence.

Urine leak and delayed healing

The new bladder-to-urethra join may heal slowly because irradiated tissues have reduced blood supply. A urinary catheter may need to remain in place longer, and imaging may be required before its removal. Persistent leakage can require drainage or further intervention.

Rectal injury and urinary fistula

The rectum can be densely adherent to the prostate after radiotherapy. Rectal injury is uncommon in expert contemporary practice but occurs more often than during primary prostatectomy and can be serious. It may require repair, temporary bowel diversion or, rarely, more extensive surgery. An abnormal connection between the urinary tract and rectum—a rectourinary fistula—is rare but particularly difficult to treat.

Other surgical risks

Other possible complications include bleeding or transfusion, infection, blood clots, lymphocele after lymph-node dissection, injury to nearby structures, anaesthetic complications, chronic pelvic pain and the need for further procedures.

Cancer may still recur

Even when preoperative imaging suggests local disease, microscopic cancer may already exist outside the prostate. PSA may therefore remain detectable or rise again after surgery. Further treatment—such as hormonal therapy, systemic therapy or selected metastasis-directed treatment—may still be required.

Are there alternatives?

Depending on the cancer, previous treatment, anatomy, urinary function and patient priorities, alternatives may include:

  • active monitoring for a slow or low-risk recurrence;
  • androgen-deprivation therapy, sometimes with additional systemic treatment;
  • salvage brachytherapy or stereotactic re-irradiation;
  • cryotherapy;
  • high-intensity focused ultrasound (HIFU); or
  • focal salvage treatment in carefully selected cases.

No single salvage treatment is best for every patient. Available studies are mostly non-randomised and use differing definitions. A large meta-analysis found broadly similar five-year cancer control among local salvage methods, but severe urinary toxicity was higher after salvage prostatectomy than after modern re-irradiation approaches. Treatment should therefore be selected through shared decision-making rather than on cancer-control figures alone.

The bottom line

Radical prostatectomy after prostate radiotherapy is possible and can be curative, but it is not a routine operation. The best candidate is generally a fit man with biopsy-proven, clinically significant recurrence confined to the prostate, no metastatic disease on appropriate staging, a meaningful life expectancy and a clear understanding of the potential functional consequences.

Accurate staging, confirmation by biopsy, assessment of baseline urinary function and review by an experienced multidisciplinary team are essential. The decision must balance the chance of durable cancer control against the higher risks of urinary incontinence, erectile dysfunction, urinary narrowing, poor healing and rectal complications.

Focal Laser Therapy for Localised Prostate Cancer: What Do We Know?

/0 Comments/in , /by

Focal therapy is an evolving approach to treating selected prostate cancers. Instead of treating or removing the entire prostate, it aims to destroy the identified cancer while preserving as much surrounding prostate tissue as possible.

One technique under investigation uses laser energy delivered through a fine fibre placed into the prostate. Early clinical reports are encouraging, but focal laser therapy is not suitable for every cancer and long-term evidence remains limited compared with established treatments such as radical prostatectomy and radiotherapy.

This article explains the disease, the principle of focal laser ablation, the early Guy’s Hospital pilot and the questions patients should consider before choosing treatment. It does not recommend a particular product, device or provider.

Understanding localised prostate cancer

Localised prostate cancer appears confined to the prostate on the available investigations. However, cancers vary greatly in their grade, size, position and biological behaviour.

Assessment commonly considers:

  • PSA level and PSA density
  • digital rectal examination findings
  • multiparametric prostate MRI
  • prostate-biopsy grade, often reported using Grade Group
  • number, position and extent of positive biopsy cores
  • whether clinically significant cancer is present in one or several parts of the prostate
  • the patient’s age, health, life expectancy and preferences
  • staging investigations where indicated

Some low-risk cancers may be monitored safely with active surveillance. Other cancers require treatment because their features suggest a meaningful risk of growth or spread.

What is focal therapy?

Focal therapy treats the known area of clinically significant cancer rather than the whole prostate. Depending on the extent and location of disease, treatment may target a small focus, a larger region or one side of the gland.

Energy sources used or investigated for focal therapy include:

  • high-intensity focused ultrasound
  • cryotherapy
  • irreversible electroporation
  • focal laser ablation
  • other thermal or energy-based techniques

These methods are not interchangeable. Each has different equipment, treatment planning, evidence, limitations and regulatory status.

How does focal laser ablation work?

Focal laser ablation delivers laser energy through a thin fibre positioned within the planned treatment area. The energy heats and destroys targeted tissue.

Placement may be performed through the perineum, the area between the scrotum and anus, with MRI and ultrasound information used to guide treatment planning and positioning. Temperature monitoring, cooling systems or other safeguards may be used according to the particular technique.

The intended advantage is to treat the cancer focus while reducing injury to structures involved in urinary continence, erections and bowel function. This is a treatment aim, not a guarantee. Damage to surrounding tissue and functional side effects remain possible.

What did the Guy’s Hospital pilot report?

Guy’s Hospital in London began a pilot involving 30 patients with localised prostate cancer. According to the hospital information reported by the BBC, assessment of the first 10 treated patients found no remaining cancer in the treated area in eight, while two had a small amount of residual cancer.

These figures should be interpreted cautiously:

  • they concern only the first 10 patients of a small pilot
  • they describe early findings in the treated area, not long-term cure
  • cancer may be present elsewhere in the prostate
  • follow-up was not long enough to establish durability, metastasis prevention or survival benefit
  • results from carefully selected research participants may not apply to all patients

The pilot includes ongoing follow-up, including imaging. Larger studies, longer observation and peer-reviewed comparative evidence are needed before firm conclusions can be drawn about long-term cancer control and functional outcomes.

Who might be considered for focal therapy?

Focal therapy may be discussed for carefully selected patients whose clinically significant cancer can be identified and targeted while untreated areas can be monitored reliably.

Selection may take account of:

  • MRI-visible disease
  • biopsy confirmation and cancer grade
  • location, volume and number of cancer foci
  • proximity to the urethra, urinary sphincter, rectum and neurovascular structures
  • prostate size and anatomy
  • previous prostate treatment
  • ability and willingness to undergo close follow-up and repeat biopsy
  • availability of appropriate expertise and governance

Multifocal, poorly defined, extensive or higher-risk cancer may make a focal approach unsuitable. An apparently single MRI lesion does not prove that no important cancer exists elsewhere in the gland.

What assessment is needed beforehand?

Accurate mapping of the cancer is essential. Depending on the patient, assessment may include:

  • review of PSA history
  • high-quality multiparametric MRI
  • targeted and systematic transperineal biopsy
  • expert radiology and pathology review
  • staging imaging when indicated by risk
  • baseline urinary, erectile and bowel function assessment
  • discussion by a multidisciplinary prostate-cancer team

A treatment decision should not be based on MRI alone. Biopsy remains important for confirming the grade and distribution of cancer.

Potential advantages

Possible advantages for appropriately selected patients include:

  • treatment directed at the known cancer rather than the entire prostate
  • usually a shorter procedure and recovery than radical prostatectomy
  • potential for same-day discharge
  • a lower treatment burden for some patients
  • the possibility of preserving urinary and sexual function more often than with whole-gland treatment
  • retention of other treatment options if further cancer is later detected

These are potential advantages, not assured outcomes. Comparisons with surgery or radiotherapy are difficult because patient selection, outcome definitions and follow-up periods differ across studies.

Risks and limitations

Possible complications include:

  • blood in the urine or semen
  • discomfort, bruising or swelling
  • urinary infection
  • difficulty passing urine or temporary catheterisation
  • urinary retention
  • urethral narrowing
  • urinary urgency or leakage
  • erectile or ejaculatory changes
  • injury to tissue surrounding the prostate
  • residual cancer within the treated area
  • clinically significant cancer elsewhere in the prostate
  • need for repeat focal treatment or conversion to surgery or radiotherapy

Rare but serious complications may occur. The specific risk profile depends on the technology, treatment location, operator experience and individual anatomy.

Focal therapy does not remove the need for surveillance

Unlike radical prostatectomy, focal therapy leaves prostate tissue behind. PSA therefore remains detectable and cannot be interpreted in the same way as after complete prostate removal.

Follow-up may include:

  • regular PSA testing
  • clinical review
  • repeat MRI
  • targeted and systematic repeat biopsy
  • assessment of urinary and sexual function

Imaging alone may not exclude residual or recurrent cancer. Patients need to be willing to undergo structured, long-term surveillance and possible further biopsy or treatment.

How does it compare with established options?

Active surveillance

Active surveillance avoids or delays treatment in suitable patients with lower-risk disease. It involves scheduled PSA tests, MRI, examination and repeat biopsy. It avoids immediate treatment side effects but carries the burden of monitoring and the possibility that treatment will later be required.

Radical prostatectomy

Surgery removes the prostate and seminal vesicles and provides complete pathological assessment of the removed gland. It has extensive long-term evidence for selected patients but may cause urinary incontinence, erectile dysfunction, loss of ejaculation and other surgical complications.

Radiotherapy

External-beam radiotherapy and brachytherapy are established treatments for localised prostate cancer. Risks may include urinary, bowel and sexual effects, which can develop during treatment or later. Some patients also require androgen-deprivation therapy.

Focal therapy

Focal therapy attempts to balance cancer control with preservation of function. Its principal uncertainties are the selection of suitable patients, untreated cancer elsewhere in the prostate, definitions of treatment success and the lack of mature comparative and long-term cancer-control data.

What happens if cancer remains or returns?

Further management depends on the location and risk of the cancer, previous treatment and patient preference. Options may include:

  • continued surveillance in selected circumstances
  • repeat focal treatment
  • radical prostatectomy
  • radiotherapy
  • another appropriate cancer treatment

Salvage treatment after focal therapy may be technically more complex and can have different side-effect rates from primary treatment. Patients should discuss the available rescue options before choosing focal therapy, not only after treatment failure.

Australian regulatory status and access

Regulatory status, approved indications, availability, reimbursement and participation in clinical trials can change. A device being used in research overseas does not automatically mean that the same system is approved, routinely available or publicly funded in Australia.

Patients considering a particular technology should ask:

  • Is the exact device included in the Australian Register of Therapeutic Goods for the proposed use?
  • Is treatment being offered as standard care, through a clinical trial or under another access pathway?
  • What evidence supports this technique for my particular cancer?
  • What costs and follow-up procedures are involved?
  • Who will manage surveillance and any residual or recurrent cancer?

Current regulatory information should be confirmed directly through the Therapeutic Goods Administration and the treating institution. This article does not make a claim that any named focal-laser system is TGA approved.

Questions to ask your prostate-cancer team

  • What is my Grade Group and clinical risk category?
  • Is the cancer confined to one clearly targetable area?
  • How confident are we that significant cancer is not present elsewhere?
  • Is active surveillance a safe option for me?
  • What are the established alternatives and their long-term outcomes?
  • What evidence is available for this focal technique?
  • How will success be measured?
  • Will I need another biopsy?
  • What are the urinary, sexual and bowel risks?
  • What happens if the cancer is not completely treated or later recurs?
  • Is this standard treatment or part of a research study?

The bottom line

The early Guy’s Hospital experience adds to growing interest in focal laser treatment for localised prostate cancer. The reported initial findings are encouraging, but 10 early cases cannot establish long-term cure, comparative effectiveness or safety.

Focal therapy may be reasonable to discuss for carefully selected patients who understand the uncertainties and accept close surveillance. It should be considered alongside active surveillance, surgery and radiotherapy through shared decision-making with an experienced multidisciplinary team.

Regulatory status and clinical evidence should be checked at the time treatment is considered.

Cxbladder Urine Testing for Urothelial Cancer: Diagnosis, Surveillance, Accuracy and Pitfalls

/0 Comments/in , /by

Bladder cancer surveillance can feel repetitive: another cystoscopy, another urine sample and another anxious wait. This has driven interest in urine-based molecular tests that may help identify patients at very low risk of recurrent urothelial carcinoma.

One such platform is Cxbladder. It is sometimes informally called “Cx View,” but the established commercial name is Cxbladder. The version designed for patients who already have a history of urothelial cancer is Cxbladder Monitor.

Cxbladder can provide useful additional information, particularly when the clinical question is whether cancer is unlikely to be present. However, it is not a stand-alone diagnosis, does not show where a tumour is located and should not automatically replace cystoscopy, imaging or biopsy.

What is the Cxbladder test?

Cxbladder is a non-invasive laboratory test performed on voided urine. It measures the expression of five messenger RNA biomarkers associated with urothelial carcinoma:

  • IGFBP5
  • HOXA13
  • MDK
  • CDK1
  • CXCR2

The result is calculated using a proprietary algorithm. Depending on the particular Cxbladder assay, clinical variables may also be incorporated into risk assessment.

The test looks for a molecular signal shed into urine by urothelial cancer cells. It does not provide a picture of the bladder, determine tumour size or location, reliably assign stage or grade, or replace histopathological examination.

The different Cxbladder tests are not interchangeable

The name “Cxbladder” covers several tests developed for different clinical settings.

Cxbladder Triage

This is designed primarily to help identify patients with haematuria who have a low probability of urothelial cancer. It prioritises sensitivity and negative predictive value, accepting lower specificity.

Cxbladder Detect

This is intended to help identify urothelial cancer in patients undergoing diagnostic evaluation, such as those presenting with haematuria. It is not specifically designed for post-treatment surveillance.

Cxbladder Monitor

This is designed for patients with a previous diagnosis of urothelial carcinoma who are undergoing surveillance for recurrence. It is the most relevant assay for follow-up after treatment of non-muscle-invasive bladder cancer (NMIBC).

Newer or region-specific Cxbladder combinations may use different algorithms and thresholds. Performance figures from one assay should not be transferred uncritically to another.

How is the sample collected?

The patient provides a voided urine sample into the supplied collection system. No catheter is normally required. The sample is stabilised and sent to a specialised laboratory for analysis.

Collection instructions must be followed carefully. Insufficient urine, incorrect handling, contamination, excessive delay or failure to use the correct collection container may produce an invalid or unreliable result. A repeat sample may occasionally be required.

What role can Cxbladder have in initial diagnosis?

For a patient with visible or microscopic haematuria, Cxbladder may help refine the estimated probability of urothelial cancer. A low-risk result can be reassuring, especially in a carefully selected lower-risk patient.

However, haematuria can be caused by bladder cancer, upper-tract urothelial cancer, renal cancer, urinary stones, infection, benign prostate bleeding and other conditions. A urine biomarker cannot evaluate all these causes. Depending on age, symptoms and risk factors, the patient may still require cystoscopy and upper-tract imaging.

Current guideline-based haematuria assessment is risk stratified. Urine markers may support shared decision-making in selected patients, but should not delay investigation of visible haematuria or replace a complete assessment in a patient at significant risk.

How may Cxbladder Monitor be used in surveillance?

After treatment of NMIBC, conventional surveillance may include:

  • cystoscopy;
  • urine cytology in selected intermediate- and high-risk patients;
  • upper-tract imaging when indicated; and
  • biopsy or TURBT when a suspicious lesion is found.

Cxbladder Monitor may be added to this pathway to help identify patients with a low probability of recurrent disease. In selected lower-risk situations, a negative result may support extending the interval to cystoscopy or avoiding an additional cystoscopy, provided this forms part of a urologist-directed protocol.

A positive result does not prove that a recurrence is present. It usually means that further assessment, commonly cystoscopy, and sometimes cytology, enhanced cystoscopy, imaging or biopsy is warranted.

The test should be used particularly cautiously in patients with previous high-grade disease, carcinoma in situ (CIS), recent positive cytology, new haematuria, concerning symptoms or a history suggesting a high risk of progression. Missing high-grade recurrence carries much greater consequences than postponing a procedure in a genuinely low-risk patient.

How accurate is Cxbladder Monitor?

Published validation data have generally shown that Cxbladder Monitor is better at ruling out recurrence than confirming it.

Across key validation studies, reported performance has been approximately:

  • sensitivity: 91–93%;
  • negative predictive value (NPV): 96–97%;
  • specificity: approximately 34–39%; and
  • positive predictive value (PPV): approximately 21% in some validation cohorts.

One comparative study reported sensitivity of 91% and NPV of 96% for Cxbladder Monitor, outperforming cytology, NMP22 and UroVysion FISH for sensitivity in that study population. Another validation reported sensitivity of 93% and NPV of 97%.

These results need careful interpretation.

What does a negative predictive value of 97% mean?

In a study population similar to the one in which that figure was measured, about 97 of every 100 patients with a negative result did not have a detected recurrence, while approximately three could still have disease.

It does not mean the test is “97% accurate” in every patient. NPV changes with the underlying prevalence of recurrence. It will usually look higher in a low-risk population and lower when recurrence is common.

Why is the positive predictive value relatively low?

When specificity is low, many patients with a positive result will not have cancer confirmed on the subsequent assessment. A positive test is therefore a prompt to investigate, not a cancer diagnosis.

Does it detect high-grade disease better?

Urine-based biomarkers often perform better for biologically active high-grade tumours than for very small low-grade recurrences. Nevertheless, no negative urine test can guarantee that high-grade tumour or CIS is absent. Study populations also differ in the proportions of low-grade, high-grade and recently treated patients, making direct comparisons difficult.

Important pitfalls

1. A negative result can be falsely reassuring

False negatives occur. Small, low-volume or intermittently shedding tumours may release too little RNA into the urine. A diluted or poorly collected sample may also reduce the signal. A negative result must not override visible haematuria, positive cytology, a suspicious cystoscopy or a high-risk clinical history.

2. A positive result is not proof of cancer

Because Monitor is deliberately designed to be sensitive, specificity is modest. A positive result may lead to cystoscopy or biopsy that finds no tumour. The test cannot identify the lesion’s location, stage or grade.

3. Infection, inflammation and recent instrumentation complicate interpretation

Urinary infection, stones, bleeding, recent cystoscopy, catheterisation, TURBT, intravesical BCG or chemotherapy can alter urinary cellular material and the clinical context. Cxbladder includes an inflammatory-associated marker intended to reduce this “background noise,” but real-world confounding is not eliminated. Testing should be timed and interpreted by the treating urologist.

4. The test does not examine the upper urinary tract

Urothelial cancer may arise in the ureter or renal pelvis. A urine result cannot localise a tumour or replace CT urography, ureteroscopy or other upper-tract evaluation when clinically indicated.

5. It does not replace pathology

Only tissue examination can determine tumour grade, assess invasion and guide definitive treatment. Cxbladder is a risk-stratification tool rather than a histological diagnosis.

6. Performance may not generalise perfectly

Some studies were supported by or involved investigators connected with the test manufacturer. Many validation cohorts were enriched for particular risk groups and may not reflect every Australian practice. Independent prospective studies, longer follow-up and trials showing that biomarker-guided surveillance preserves oncological outcomes are especially important.

7. “Fewer cystoscopies” is not the same as “no cystoscopies”

Real-world studies suggest that Cxbladder Monitor can reduce cystoscopy frequency in selected low-risk patients. This should not be extrapolated to high-risk NMIBC or used to abandon risk-based surveillance. Cystoscopy remains the direct method of inspecting the bladder and permits immediate biopsy or resection planning.

8. Cost and access vary

Availability, laboratory turnaround time, out-of-pocket cost and reimbursement vary by location and insurer. Australian patients should confirm current access and costs with their urologist and testing provider before collection.

How does it compare with urine cytology?

Urine cytology is highly specific for high-grade urothelial carcinoma but has limited sensitivity, particularly for low-grade tumours. Cxbladder Monitor generally has higher reported sensitivity and NPV, but substantially lower specificity.

The tests therefore answer slightly different questions:

  • cytology: a clearly positive result strongly raises concern for high-grade disease;
  • Cxbladder Monitor: a negative result may help identify a low probability of recurrence; and
  • cystoscopy: directly visualises the bladder and remains central to surveillance.

Combining information may be more useful than treating any one result in isolation.

What do international guidelines say?

Major guidelines acknowledge that urinary molecular markers are improving, but remain cautious about their routine use as complete substitutes for cystoscopy.

  • The AUA/SUO NMIBC guideline states that urinary biomarkers should not replace cystoscopic evaluation during surveillance. Markers may be used in selected settings, including assessment of an equivocal cytology result or response to intravesical BCG.
  • The EAU NMIBC guideline recognises that molecular urine tests may have a future role in reducing cystoscopy frequency, particularly in lower-risk surveillance, but notes that evidence and prospective implementation data remain insufficient for a universal marker-driven schedule.
  • Guideline recommendations evolve as new trials emerge; decisions should be based on the patient’s individual recurrence and progression risk rather than the availability of a test alone.

A practical, balanced approach

Cxbladder Monitor is most helpful when the question is: “Is recurrence sufficiently unlikely that we can safely reduce or postpone an invasive investigation in this particular patient?”

It is less useful as a stand-alone answer to: “Does this patient definitely have cancer, where is it, and how aggressive is it?”

For a carefully selected patient with previous low-risk NMIBC, no new symptoms and a negative Monitor result, a biomarker-informed surveillance plan may reduce unnecessary cystoscopies. For a patient with previous CIS or high-grade tumour, positive cytology, visible haematuria or a suspicious finding, conventional investigation should not be deferred because of a negative urine test.

The result is best interpreted alongside tumour history, grade and stage, time since treatment, cystoscopy findings, cytology, imaging and the patient’s preferences.

Spinal Cord Injury and the Bladder: Upper Motor Neuron versus Lower Motor Neuron Injury

/0 Comments/in , /by

Meta description: Spinal cord injury can cause urgency, leakage, urinary retention and dangerous bladder pressures. Learn how upper and lower motor neuron injuries differ, how neurogenic bladder is investigated, and which treatments may protect the kidneys and improve continence.

Best treated in an organised spinal unit.

Why can a spinal cord injury affect the bladder?

Passing urine is not simply a bladder reflex. It requires communication between the brain, the spinal cord, the sacral nerves and the urinary sphincter. During normal bladder filling, the bladder muscle, called the detrusor, remains relaxed while the outlet stays closed. When it is appropriate to urinate, the detrusor contracts and the sphincter relaxes in a coordinated fashion.

A spinal cord injury (SCI) can interrupt these pathways. The resulting problem is called neurogenic lower urinary tract dysfunction, often shortened to neurogenic bladder. A person may develop urgency, leakage, difficulty emptying, urinary retention, or a combination of these.

The most important issue is not always the symptom that is most noticeable. A bladder may feel relatively quiet yet store urine at a pressure high enough to threaten the kidneys. Conversely, severe urgency may occur without dangerous pressure. Assessment therefore aims to answer two separate questions:

  1. Is urine being stored and emptied at a pressure that is safe for the kidneys?
  2. Does the bladder routine provide acceptable continence, independence and quality of life?

The early phase: spinal shock

Immediately after an acute SCI, the bladder commonly becomes temporarily areflexic or acontractile. It fills but does not contract effectively, causing urinary retention. Bladder sensation may also be absent. Catheter drainage is usually required in this acute phase.

This phase may last days, weeks or sometimes longer. Reflex activity can then return below a suprasacral injury and the eventual bladder pattern may be very different from the early one. For this reason, the bladder should be reassessed as the neurological situation evolves.

Upper motor neuron versus lower motor neuron bladder

The traditional distinction is useful, but it is a guide—not a substitute for urodynamic testing.

Feature Upper motor neuron pattern Lower motor neuron pattern
Typical injury site Above the sacral micturition centre, often a suprasacral spinal cord lesion Sacral cord, conus medullaris, cauda equina or sacral/peripheral nerve injury
Bladder contraction Often involuntary detrusor contractions during filling—neurogenic detrusor overactivity Weak or absent detrusor contraction—detrusor underactivity or acontractility
Outlet behaviour The sphincter may contract instead of relaxing during a bladder contraction—detrusor-sphincter dyssynergia (DSD) Outlet resistance may be reduced if sacral innervation is damaged, although obstruction from other causes can coexist
Common symptoms Urgency, frequency, reflex voiding, urge leakage, interrupted emptying and residual urine Reduced bladder sensation, infrequent voiding, straining, retention, overflow leakage and recurrent infection
Main safety concern High storage or voiding pressure, poor compliance, reflux, hydronephrosis and renal damage Chronic retention, over-distension, infection, stones and overflow incontinence
Typical emptying strategy Often clean intermittent catheterisation, sometimes combined with bladder-relaxing treatment Clean intermittent catheterisation is commonly required when detrusor contraction is inadequate

Upper motor neuron injury: the overactive but poorly coordinated bladder

With an injury above the sacral spinal cord, the local sacral reflex circuit may remain intact but lose normal coordination from the brain. After spinal shock resolves, the bladder may contract unexpectedly during filling. At the same time, the external urinary sphincter may fail to relax or may tighten when the bladder contracts.

This combination of detrusor overactivity and DSD can produce:

  • urgency and reflex urinary leakage;
  • a stop–start urinary stream or incomplete emptying;
  • high bladder pressure;
  • urinary tract infection and bladder stones;
  • vesicoureteric reflux, hydronephrosis and, if not controlled, renal impairment.

People with SCI at or above approximately T6 can also develop autonomic dysreflexia. Bladder distension, a blocked catheter, infection or urological procedures may trigger sudden severe hypertension, a pounding headache, sweating or flushing above the injury, anxiety, nasal congestion and a slow or irregular pulse. This is a medical emergency: sit the person upright, check the catheter and drainage system promptly, and seek urgent medical assistance if symptoms or elevated blood pressure persist.

Lower motor neuron injury: the bladder that cannot squeeze effectively

Damage involving the sacral cord, conus medullaris, cauda equina or sacral nerves can interrupt the reflex pathway to the bladder. The detrusor may contract weakly or not at all. Sensation of filling may be reduced, so the bladder can become very full without the usual warning.

Possible features include:

  • difficulty starting or inability to pass urine;
  • infrequent voiding and a weak stream;
  • abdominal straining to empty;
  • a large post-void residual;
  • overflow leakage;
  • recurrent infection, stones or bladder over-distension.

If outlet innervation is also impaired, stress leakage can coexist with retention. A lower motor neuron lesion is therefore not automatically a “low-pressure and harmless” bladder.

Why the neurological level does not tell the whole story

Real-life bladder dysfunction does not always fit neatly into one box. An incomplete lesion can preserve some sensation or voluntary control. Injuries around the conus may affect upper and lower motor neuron pathways together. Pre-existing prostate enlargement, urethral stricture, pelvic floor dysfunction, medications, constipation and infection can further change bladder behaviour.

Most importantly, neurological examination and lesion level do not reliably predict bladder pressure or sphincter coordination. Symptoms can also change over time. Urodynamic findings, not the label alone, should guide risk assessment and treatment.

How is bladder function investigated after SCI?

Clinical assessment

Assessment usually includes:

  • the level, completeness, timing and cause of the SCI;
  • bladder sensation, urgency, leakage, voiding method and catheter routine;
  • recurrent infections, visible blood, stones, catheter blockage and episodes of autonomic dysreflexia;
  • fluid intake, urine output and a bladder diary where practical;
  • bowel function and constipation;
  • mobility, hand function, cognition, carer support and personal goals;
  • medicines that may affect storage or emptying;
  • abdominal, genital, perineal and focused neurological examination.

Basic tests

Depending on the clinical situation, these may include:

  • urinalysis and urine culture when infection is suspected;
  • measurement of the post-void residual by ultrasound or catheter;
  • kidney function blood tests, while recognising that serum creatinine may underestimate renal impairment in people with low muscle mass;
  • renal and bladder ultrasound to look for hydronephrosis, stones, bladder wall changes and residual urine;
  • other renal function assessment when clinically indicated.

A urine culture should not be used to screen for and repeatedly treat bacteria in an otherwise well catheter user. Asymptomatic bacteriuria is common and generally should not be treated, apart from recognised exceptions such as pregnancy or before selected urological procedures that breach the urinary mucosa.

Urodynamic studies

Multichannel urodynamics, sometimes combined with X-ray imaging as video-urodynamics, is central when the risk is unknown or potentially significant. It can determine:

  • bladder sensation and capacity;
  • detrusor overactivity;
  • bladder compliance and storage pressure;
  • detrusor strength during attempted voiding;
  • sphincter coordination or DSD;
  • leakage pressure, residual urine and, with video, reflux or outlet anatomy.

The test is not merely to explain incontinence. Its crucial role is to identify a hostile, high-pressure bladder before silent upper urinary tract damage develops. Repeat testing may be required after treatment, when symptoms change, after recurrent complications, or when renal imaging deteriorates.

Other tests

Cystoscopy is not a routine screening test for every person with SCI. It is used for a specific indication, such as visible blood in the urine, recurrent catheter blockage, suspected stones, difficult catheterisation, urethral injury or another anatomical concern. CT, MRI or nuclear renal imaging may be added when ultrasound or the clinical picture warrants it.

Management: protecting the kidneys while fitting treatment to the person

Treatment should be individualised with a urologist, rehabilitation physician, continence nurse and allied health team. The aim is low-pressure storage, reliable emptying, continence where achievable, fewer complications and a routine the person can realistically manage.

1. Reliable bladder emptying

Clean intermittent catheterisation (CIC/ISC) is often the preferred method when the bladder does not empty adequately. It avoids a continuously indwelling tube and can provide predictable, low-pressure drainage. Frequency is tailored to fluid intake, catheterised volumes, bladder pressure and the treatment plan. Hand function, access to the urethra, cognition, carer assistance, work and travel must all be considered.

If intermittent catheterisation is not feasible, an indwelling catheter may be required. When long-term indwelling drainage is necessary, a suprapubic catheter is often favoured over a urethral catheter because it avoids chronic urethral pressure and erosion, although it still carries risks of infection, blockage, leakage and stones.

Reflex voiding into a sheath system may suit selected men, but only after confirming that bladder pressures and emptying are safe. Regular reliance on abdominal straining or the Credé manoeuvre is generally discouraged because it can generate high pressure and may not empty the bladder adequately.

2. Reducing overactivity and unsafe storage pressure

Options include:

  • antimuscarinic medicines, which reduce involuntary bladder contractions but can cause dry mouth, constipation, blurred vision and cognitive adverse effects;
  • a beta-3 agonist, which may improve storage with a different side-effect profile but requires attention to blood pressure and other contraindications;
  • carefully selected combination therapy;
  • intradetrusor botulinum toxin A (Botox) when tablets are ineffective or poorly tolerated. This can markedly reduce detrusor overactivity and pressure but may increase urinary retention; the person must be willing and able to catheterise if required.

Alpha-blockers may reduce outlet resistance in selected people who void spontaneously, but they do not correct every form of DSD and may cause dizziness or low blood pressure.

3. Managing sphincter dyssynergia or outlet resistance

Where DSD prevents safe emptying, management may include intermittent catheterisation, bladder-relaxing therapy, selected alpha-blocker use, sphincter botulinum toxin, or less commonly, an outlet procedure such as sphincterotomy in carefully selected men using sheath drainage. Any procedure that lowers outlet resistance may improve emptying but can trade obstruction for incontinence.

4. Treating an acontractile lower motor neuron bladder

For a bladder that cannot contract effectively, CIC is usually the mainstay. There is no consistently effective oral medicine that restores a truly acontractile detrusor. Correcting reversible contributors: constipation, medicines, infection or mechanical obstruction remains important. Outlet surgery should only be considered when a proven obstruction is present and the likely effect on continence and catheterisation has been discussed.

5. Reconstructive surgery and urinary diversion

If conservative and minimally invasive measures cannot produce safe storage or practical drainage, options may include:

  • augmentation cystoplasty to increase capacity and reduce pressure;
  • creation of a continent catheterisable channel, such as a Mitrofanoff-type channel;
  • selected outlet continence surgery when sphincter weakness is the main problem;
  • urinary diversion, with or without bladder removal, in complex or refractory cases.

These are major procedures with long-term surveillance requirements and should be undertaken in an experienced neuro-urology service.

What about sacral neuromodulation?

Sacral neuromodulation is not a routine treatment for a complete spinal cord injury with established DSD or an acontractile bladder. It may be considered in carefully selected people with an incomplete, stable neurological lesion and suitable bladder function, but evidence in SCI is more limited than it is for non-neurogenic overactive bladder or non-obstructive retention. A test phase and specialist assessment are essential.

Follow-up is lifelong

Neurogenic bladder can change even when the spinal injury itself appears stable. Follow-up intensity is based on risk, bladder management method and previous complications. It may include review of symptoms and catheter volumes, renal function assessment, upper urinary tract imaging and repeat urodynamics in moderate- or high-risk patients.

Seek earlier review for:

  • new or worsening leakage;
  • difficulty catheterising or repeated catheter blockage;
  • recurrent symptomatic infection or fever;
  • visible blood in the urine;
  • flank pain, stones or hydronephrosis;
  • increasing residual urine;
  • new autonomic dysreflexia;
  • deterioration in kidney function.

The take-home message

An upper motor neuron injury often produces an overactive bladder that may fight against a closed sphincter. A lower motor neuron injury more often produces a poorly contracting bladder with retention. Both patterns can cause leakage, infection and kidney damage, and mixed patterns are common.

The safest plan is not based on the injury label alone. It combines symptoms, neurological assessment, kidney surveillance and where indicated, urodynamic testing. With an individualised catheter, medication, Botox or surgical plan, most people can achieve safer bladder pressures and a more predictable routine.

Medical disclaimer: This article provides general education and does not replace individual medical assessment. Sudden severe headache, sweating or flushing with high blood pressure in a person with SCI—particularly with an injury at or above T6—may represent autonomic dysreflexia and requires urgent attention.

How a Stroke Can Affect Bladder Function

/0 Comments/in , /by

A cerebrovascular accident (CVA), more commonly called a stroke, can affect much more than movement and speech. It can also disrupt the communication between the brain and bladder, leading to urgency, urinary leakage, difficulty emptying the bladder or a combination of these problems.

Bladder difficulties are common after stroke, particularly during the early stages of recovery. They can cause embarrassment, interfere with rehabilitation, disturb sleep and increase the risks of falls, skin problems and urinary tract infection. Fortunately, many patients improve as the brain recovers, and persistent symptoms can usually be managed with an individualised bladder rehabilitation and treatment plan.

How does the brain normally control the bladder?

The bladder stores urine at a low pressure until it is convenient to empty. This depends on coordinated communication between:

  • The frontal lobes, which help recognise bladder filling and suppress urination until an appropriate time.
  • Deeper brain centres involved in bladder sensation and behavioural control.
  • The pontine micturition centre in the brainstem, which coordinates contraction of the bladder with relaxation of the urinary sphincter.
  • The spinal cord and peripheral nerves that carry messages between the brain, bladder and sphincter.

A stroke may interrupt one or more of these pathways. The resulting bladder problem depends on the location and extent of the stroke, the patient’s previous bladder function and the presence of other conditions such as prostate enlargement, diabetes, constipation or reduced mobility.

What bladder problems can occur after a stroke?

Urgency and urge urinary incontinence

The most common problem is a sudden, compelling need to pass urine that may be difficult to postpone. Some patients leak before reaching the toilet.

This often results from detrusor overactivity, in which the bladder muscle contracts involuntarily during filling because the brain is no longer suppressing it normally.

Associated symptoms can include:

  • Passing urine frequently.
  • Waking several times at night to urinate.
  • Sudden urgency.
  • Leakage associated with urgency.
  • Bedwetting.
  • Reduced warning before urination.

Difficulty emptying the bladder

Some patients develop a weak or poorly coordinated bladder contraction and cannot empty effectively. This may cause:

  • Difficulty starting urination.
  • A slow or interrupted urinary stream.
  • Straining to pass urine.
  • A sensation of incomplete emptying.
  • Frequent passage of small amounts.
  • Overflow leakage from an overfilled bladder.
  • Recurrent urinary infections.

Urinary retention may be more likely during the acute phase of stroke because of reduced consciousness, immobility, constipation, medication effects, pain, infection or a pre-existing obstruction such as an enlarged prostate.

Functional incontinence

Not every episode of leakage is caused by abnormal bladder contractions. A patient may recognise the need to urinate but be unable to reach or use the toilet because of:

  • Weakness or paralysis.
  • Poor balance or slow mobility.
  • Visual impairment.
  • Difficulty removing clothing.
  • Communication problems.
  • Confusion, memory loss or reduced awareness.
  • An inaccessible toilet or lack of timely assistance.

This is called functional incontinence. Treating the bladder alone will not solve it; the physical and environmental barriers must also be addressed.

Loss of bladder awareness

A stroke can reduce awareness of bladder filling. The patient may not recognise the need to urinate until leakage occurs—or may remain unaware that the bladder is full.

Stress urinary incontinence

Leakage with coughing, sneezing, standing or exertion is not usually caused directly by stroke, but pre-existing pelvic-floor weakness may become more noticeable when mobility and general muscle function decline.

Nocturia and nighttime incontinence

Nighttime urination may be caused by an overactive bladder, sleep disturbance, leg swelling, obstructive sleep apnoea, medication timing or increased nighttime urine production. It is important because repeated attempts to reach the bathroom can significantly increase the risk of falls.

Does the site of the stroke predict the bladder problem?

There are broad associations between the area of brain injury and the type of bladder dysfunction, but the relationship is not exact enough to base treatment on the brain scan alone.

Frontal and subcortical strokes are frequently associated with urgency and detrusor overactivity. Brainstem strokes can interfere with coordination between the bladder and urinary sphincter, while larger strokes may impair bladder sensation, mobility and awareness.

The bladder pattern can also change during recovery. This is why treatment should be based on the patient’s current symptoms and objective bladder assessment rather than the location of the stroke alone.

How is bladder dysfunction assessed?

Assessment should consider the bladder, the patient’s neurological recovery and the practical circumstances surrounding each episode of leakage.

Medical and medication history

Important questions include:

  • Was urgency, nocturia or poor urinary flow present before the stroke?
  • When did the symptoms begin?
  • Is the patient aware of bladder filling?
  • Can the patient reach and use the toilet independently?
  • Is there constipation, pain, visible blood in the urine or fever?
  • What fluids, caffeine and alcohol are being consumed?
  • Could medication be contributing?

Diuretics, sedatives, opioids and some medications with anticholinergic effects can aggravate urinary symptoms, confusion or retention.

Bladder diary

A bladder diary records fluid intake, the time and volume of each urination, urgency and leakage episodes. It can help distinguish reduced bladder capacity from excessive urine production or predominantly functional incontinence.

Physical examination

The assessment may include examination of the abdomen, genital area, prostate where appropriate, pelvic floor, mobility, cognition, sensation and neurological function.

Urine testing

Urinalysis and urine culture when clinically indicated, can identify infection or blood in the urine. Bacteria in the urine without urinary symptoms do not automatically require antibiotics.

Bladder scan and post-void residual

A painless ultrasound bladder scan measures the urine remaining after urination. This is particularly useful when there is a weak stream, retention, recurrent infection, overflow leakage or before treatments that could make emptying more difficult.

Additional investigations

Depending on the circumstances, evaluation may include:

  • Kidney function blood tests.
  • Urinary flow testing.
  • Ultrasound of the kidneys and bladder.
  • Cystoscopy when there is haematuria, suspected obstruction or another appropriate indication.
  • Urodynamic studies.

Are urodynamic studies always necessary?

No. Many patients with straightforward urgency or functional incontinence can begin conservative treatment after clinical assessment, urine testing and measurement of the post-void residual.

Urodynamic studies may be helpful when:

  • The symptoms and clinical findings do not agree.
  • Both urgency and poor emptying are present.
  • There is persistent or unexplained urinary retention.
  • Initial treatment has failed.
  • An invasive treatment such as bladder Botox is being considered.
  • There is concern about obstruction, weak bladder contraction or poor bladder compliance.
  • Previous prostate, bladder or continence surgery complicates the diagnosis.

Urodynamics can distinguish an overactive bladder from impaired bladder contractility, obstruction or sphincter discoordination. This helps avoid giving treatment that reduces bladder contractions to someone who already empties poorly.

Treatment options

Treatment should be based on the bladder abnormality, the patient’s functional ability and their personal goals. Family members, continence nurses, physiotherapists, occupational therapists, rehabilitation physicians and urologists may all contribute.

Treat reversible factors

The first step is to identify problems that may be aggravating bladder control, including:

  • Urinary infection.
  • Constipation or faecal impaction.
  • Excessive caffeine or alcohol.
  • Excessive or poorly timed fluid intake.
  • Uncontrolled diabetes.
  • Leg swelling and nighttime fluid redistribution.
  • Medication side effects.
  • Prostate obstruction.
  • Reduced access to the toilet.

Adequate hydration remains important. Simply restricting fluid can produce concentrated urine, constipation and bladder irritation.

Prompted or timed toileting

Scheduled toileting can be very effective, particularly when memory, mobility or awareness is impaired.

Options include:

  • Timed voiding: visiting the toilet at regular planned intervals.
  • Prompted voiding: a carer reminds and assists the patient to use the toilet.
  • Habit retraining: the schedule is matched to the patient’s usual bladder pattern.
  • Bladder training: gradually increasing the interval between toilet visits when the patient can recognise and suppress urgency.

Easy-to-remove clothing, a bedside commode, urinal, improved lighting and a clear path to the toilet can make a considerable difference.

Pelvic-floor rehabilitation

Pelvic-floor muscle training may improve urinary control in appropriately selected patients who can identify and contract these muscles. A continence or pelvic-floor physiotherapist can adapt the program for weakness, impaired coordination or cognitive limitations following stroke.

Medication for urgency and overactive bladder

Medication may be considered when conservative measures are insufficient.

Antimuscarinic medication

Medicines such as solifenacin, darifenacin, oxybutynin or trospium can reduce involuntary bladder contractions. Possible adverse effects include:

  • Dry mouth.
  • Constipation.
  • Blurred vision.
  • Difficulty emptying the bladder.
  • Confusion or cognitive deterioration.

These medicines should be selected cautiously after stroke, particularly in older patients, those with cognitive impairment, constipation, glaucoma or an elevated post-void residual. The total anticholinergic burden from all medications should be reviewed.

Beta-3 agonists

Mirabegron relaxes the bladder during filling and may have fewer dry-mouth and cognitive adverse effects than antimuscarinic treatment. Blood pressure should be checked because mirabegron may worsen hypertension. Residual urine should also be monitored when there is concern about poor emptying.

Vibegron is another beta-3 agonist, although availability and funding can vary.

Management of incomplete emptying or retention

Treatment depends on the cause and severity.

Options may include:

  • Reviewing medicines that impair bladder contraction.
  • Treating constipation and infection.
  • Managing prostate or urethral obstruction when present.
  • Double voiding.
  • Intermittent catheterisation.

Clean intermittent catheterisation is generally preferred when the bladder cannot empty safely and the patient or carer can perform it. An indwelling urethral catheter may sometimes be necessary during the acute phase, but prolonged unnecessary use should be avoided because of infection, urethral trauma and bladder-stone risks.

A suprapubic catheter may be considered when long-term catheter drainage is unavoidable and urethral catheterisation is unsuitable.

Botulinum toxin injections into the bladder

Botulinum toxin A, commonly called bladder Botox, can reduce severe detrusor overactivity when medication has been ineffective or poorly tolerated.

It may significantly improve urgency and leakage, but it can also weaken bladder emptying. The patient must understand that intermittent catheterisation may be required, sometimes for several months. Careful selection, measurement of residual urine and appropriate follow-up are essential.

Neuromodulation

Posterior tibial nerve stimulation may help some patients with urgency and overactive bladder symptoms. It is minimally invasive but usually requires repeated treatment sessions.

Sacral neuromodulation can be effective in selected people with refractory urinary urgency, urge incontinence or non-obstructive retention. Evidence specifically in post-stroke patients is more limited than in the general overactive-bladder population. The patient’s neurological stability, cognition, mobility, ability to operate the device and need for future MRI examinations should be considered.

Continence products and skin care

Pads, absorbent underwear, mattress protection and external collecting devices can preserve dignity while recovery and treatment continue. They should support, not replace, proper assessment and rehabilitation.

Regular skin care is important, particularly when mobility is limited. Condom drainage systems may help selected men, but correct fitting and skin monitoring are essential.

Can bladder control improve after a stroke?

Yes. Many patients experience substantial improvement during the first weeks and months as consciousness, mobility, communication and neurological control recover.

Persistent urinary incontinence, however, can be a marker of a more severe stroke and may be associated with greater disability. It should not be dismissed as an inevitable consequence of ageing or brain injury. Early assessment and an active continence program can improve independence, participation in rehabilitation and quality of life.

When should medical help be sought urgently?

Prompt medical assessment is required for:

  • Complete inability to pass urine.
  • A painful or visibly swollen lower abdomen.
  • Fever, chills, confusion or suspected urinary infection.
  • Visible blood in the urine.
  • New flank pain.
  • Recurrent infections.
  • Increasing residual urine.
  • New leg weakness, numbness or loss of bowel control.
  • Sudden new neurological symptoms, which may represent another stroke.

In Australia, sudden facial weakness, arm weakness or speech disturbance should be treated as an emergency—call 000 immediately.

The key message

Bladder problems following a stroke are common, but they are not all the same. Leakage may result from an overactive bladder, impaired awareness, poor mobility, urinary retention, obstruction or several factors acting together.

Successful management begins by determining why the problem is occurring. A combination of bladder rehabilitation, environmental assistance, pelvic-floor therapy, carefully selected medication, catheterisation or specialist intervention can then be tailored to the individual patient.

To My Bundaberg Patients: An Apology and an Explanation

/0 Comments/in /by

I am sorry that I have had to cancel some of your procedures and appointments

Providing urological care to patients in Bundaberg and the surrounding region has been important to me, and I have greatly valued the relationships I have developed with my patients, their families, local doctors, nurses and hospital staff.

That is why having to cancel a consultation or surgical procedure at short notice is something I find particularly difficult.

Recently, however, I have had to make these decisions because of repeated last-minute changes and cancellations affecting flights I have booked with Qantas and Link Airways between Brisbane and Bundaberg.

To every patient who has been affected, I am sincerely sorry.

A cancelled operation is not simply a cancelled appointment

I know how much preparation goes into coming to hospital.

You may have taken time off work. Your partner may have taken leave to look after you. Someone may have driven several hours to be with you. You may have organised childcare, stopped medications, completed tests and fasted from the night before.

Most importantly, you may have spent days or weeks preparing yourself mentally for an operation.

Then, sometimes on the morning of your procedure, you are told that your surgeon cannot get to Bundaberg because the flight has been cancelled.

I can only imagine how frustrating, disappointing and, at times, distressing that must be.

You deserve better than that.

Regional patients deserve reliable transport too

Specialist medical care in regional Australia already comes with challenges that patients living in major cities often do not experience.

Visiting specialists are one way of bringing care closer to patients rather than expecting every patient to travel to Brisbane.

But that model depends upon something very basic:

The aeroplane actually needs to fly.

When an airline cancels or materially changes a regional flight at the last minute, the consequences extend well beyond inconvenience for an individual passenger.

In my circumstances, one cancelled seat can mean an entire operating list or clinic is disrupted.

Behind that operating list are real people.

Patients have prepared for surgery. Theatre staff and anaesthetists have been rostered. Hospital beds and equipment have been organised. Families have changed their plans. General practitioners have referred patients expecting them to receive specialist care.

A last-minute flight cancellation can unravel all of that remarkably quickly.

My frustration with Qantas and Link Airways

I appreciate that airlines sometimes need to cancel flights. Weather, aircraft safety, operational problems and other circumstances can make cancellation unavoidable.

However, the frequency and particularly the last-minute nature of the disruptions I have personally experienced with Qantas and Link Airways have made maintaining a dependable visiting surgical service to Bundaberg increasingly difficult.

This is not simply about the inconvenience caused to me as a traveller.

It is about the patients waiting at the other end of the flight.

Regional air services are part of the infrastructure that allows professionals, businesses and healthcare services to function outside Australia’s major cities.

I believe airlines operating regional routes need to recognise the broader consequences when those services become unreliable, particularly when cancellations occur with little notice and there is no realistic alternative that allows a specialist to reach the region in time.

Why can’t I simply take the next flight?

I wish it were that easy.

An operating theatre is not something that can simply be shifted several hours down the timetable.

An operation requires an anaesthetist, nursing staff, theatre personnel, specialised equipment, hospital beds and sufficient postoperative support. Other patients are also scheduled for procedures throughout the day.

Most importantly, surgery should never be rushed.

If a cancelled flight means I cannot arrive with enough time to safely complete an operating list, I will cancel or postpone the procedure rather than compromise patient care.

That decision is deeply frustrating, but patient safety will always win that argument.

To the patients I have disappointed

This is the part that matters most to me.

If you have been sitting at home fasting since midnight, or already travelled to hospital, only to discover that your operation cannot proceed, I am very sorry.

If your consultation has been postponed after you arranged work, travel or family commitments around it, I am sorry.

And if you have wondered whether your appointment or procedure was somehow unimportant, please know that it was not.

I know there is a person behind every name on my operating list.

I know that you have a family, responsibilities, anxieties and plans. I also know that being told “we will need to reschedule” does not magically undo everything you have already organised.

I remain committed to regional patients

I strongly believe that Australians living in regional communities should have reasonable access to specialist healthcare.

Whenever it is practical and safe to do so, I want to continue supporting patients outside Brisbane and reducing the need for people to make long journeys simply to see a specialist.

But regional specialist medicine cannot function in isolation.

It requires hospitals, doctors, nurses, allied health professionals and transport services to work together. Reliable regional aviation is part of that chain.

When that link repeatedly fails, patients ultimately carry the consequences.

Thank you

To my Bundaberg patients, their families, the local doctors who refer to me, and the wonderful nursing, administrative and theatre staff who have had to deal with the consequences of these disruptions:

Thank you for your patience, understanding and support.

And once again, to any patient whose care I have had to postpone because I could not get to Bundaberg:

I am genuinely sorry.

I will continue to do everything reasonably within my control to provide you with reliable, safe and compassionate urological care.

Perhaps there is also a broader conversation that needs to occur about the reliability of regional aviation and the people who depend upon it.

Because when a regional flight is cancelled, sometimes much more than a flight is cancelled.
