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





  • Ureteric perforation
  • Stricturing / Narrowing
  • Disruption of ureter
  • Stent Irritation
  • Procedure abandoned due to bleeding
