Ureteroscopic endopyelotomy without preoperative stenting is an effective treatment for ureteropelvic junction obstruction. This minimally invasive approach achieved an 81% success rate in a recent study.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Ureteropelvic junction (UPJ) obstruction is commonly treated with endopyelotomy.
  • The optimal approach (percutaneous vs. ureteroscopic) and need for preoperative stenting remain debated.

Purpose of the Study:

  • To evaluate the efficacy and safety of ureteroscopic endopyelotomy without preoperative stenting for UPJ obstruction.
  • To assess outcomes in patients treated with this technique.

Main Methods:

  • Retrospective review of 21 patients with UPJ obstruction treated with ureteroscopic endopyelotomy.
  • No preoperative stenting was used; endoluminal ultrasound guided periureteral anatomy imaging.
  • Success defined as pain-free status and resolution of obstruction on diuretic renal scintigraphy after at least 1 year of follow-up.

Main Results:

  • An 81% success rate (17 of 21 patients) was achieved.
  • Complications were infrequent, including stent irritation, UTI, and one case of stent displacement.
  • The presence of crossing vessels impacted success rates (67% with vs. 100% without).

Conclusions:

  • Ureteroscopic endopyelotomy without preoperative stenting is a safe and effective treatment option for UPJ obstruction.
  • This approach avoids the complications associated with indwelling stents.
