Why is it done?

  • This procedure is performed when the prostate gland is enlarged to such an extent that medication cannot relieve the urinary symptoms.
  • Symptoms include: a weak stream, nightly urination, frequent urination, inability to urinate, (LUTS) kidney failure due to the weak urination (obstruction), bladder stones, recurrent bladder infections.
  • Medication such as Flomaxtra, Xatral Minipress etc. should always be given as a first resort.
  • Step-up therapy should have been used for prostates larger than 35-50cc with either Duodart, Avodart or Proscar.
  • Prostate cancer first needs to be ruled out by doing a PSA, and when indicated, with a 3T MRI scan of the prostate with an abnormal PSA with a possible prostate biopsy of any suspicious lesions.
  • A TUVP can also be performed to disobstruct a severe prostate cancer, to allow a normal urination process.

How is it done?

    • patients will receive a general anaesthesia, unless contra-indicated.
    • A cystoscopy is performed by placing a camera in the urethra with the help of lignocaine gel.
    • The inside of the bladder is viewed for pathology. If any suspicious lesions are seen, a biopsy will be taken.
    • A vaporization of the prostate is then started and should take 60-120 minutes depending on the size of the prostate.


  • Prophylactic antibiotics will be given to prevent any infections.
  • Post– operative antibiotics will be continued for 10 days.
  • No specimen will be obtained due to vaporization, unless PSA was suspicious and a MRI with view to prostate biopsy has excluded a prostate cancer.

What can go wrong?
