Summary

Endourologic treatment for ureteropelvic junction obstruction (UPJO) due to high insertion is effective. High insertion does not contraindicate endopyelotomy, showing comparable success rates to other UPJO cases.

Area of Science:

  • Urology
  • Endourology

Background:

  • Ureteropelvic junction obstruction (UPJO) can be caused by high insertion of the ureter into the renal pelvis (HIUPJO).
  • Endourologic techniques offer minimally invasive treatment options for UPJO.

Purpose of the Study:

  • To evaluate the outcomes of endourologic treatment for primary UPJO specifically caused by HIUPJO.
  • To determine if HIUPJO is a contraindication for endopyelotomy.

Main Methods:

  • Retrospective analysis of 10 patients with HIUPJO treated with endopyelotomy (retrograde or antegrade).
  • Stent placement for an average of 5.3 weeks post-procedure.
  • Success assessed via subjective (patient questionnaires, pain scales) and objective (diuretic renal scan, Whitaker test) measures.

Main Results:

  • Subjective success rate was 80% at an average follow-up of 27 months.
  • Objective success rate was 70% at a mean follow-up of 26 months.
  • Overall, 60% of patients achieved both subjective and objective success.

Conclusions:

  • Endourologic treatment, including endopyelotomy, is a viable option for UPJO caused by HIUPJO.
  • The success rates for endopyelotomy in HIUPJO cases are comparable to those in non-HIUPJO cases.
  • High insertion of the ureter into the renal pelvis should not be considered a contraindication for endopyelotomy.
