Item Number:
Why is it done?
- Viewing suspicious lesions in upper urinary tracts (ureter and renal pelvis)
- Flexible ureterorenoscopy to review inside of the renal pelvis and renal calyces
- Removal of the lesion using laser
- Rigid is better for the ureteric inspection
How is it done?
- Patients will receive general anaesthesia.
- Prophylactic antibiotics are given.
- The correct kidney is identified and marked while you are awake
- You would have had a cystoscopy with retrograde pyelogram 10 days prior with the placement of a ureteric stent to prepare your ureter
- A cystoscopy will be done first to remove the stent and 2 guidewires will be placed to enable access up the ureter
- Depending on the position of the lesion, either a rigid or flexible uretero-renoscope will be used.
- Suspicious lesions may be biopsied and fulgurated.
- Laser fulguration or Diathermy may be used.
- Catheters will be removed the next morning depending on the presence of blood in the urine
- Extended use of a ureteric stent may be advised, depending on the degree of bleeding
Complications
Side–effects
- Ureteric perforation
- Stricturing / Narrowing
- Disruption of ureter
