Summary

Persistent dilatation using double J stents effectively treated pelvis-ureter junction stricture in 21 patients. This minimally invasive approach led to symptom resolution and improved kidney function in most cases.

Area of Science:

  • Urology
  • Nephrology

Context:

  • Pelvic-ureter junction (PUJ) stricture is a common cause of upper urinary tract obstruction.
  • Traditional treatments can be invasive and associated with complications.

Purpose:

  • To evaluate the efficacy of persistent dilatation with indwelling double J stents for treating PUJ stricture.

Summary:

  • Twenty-one patients with 27 affected ureters underwent retrograde insertion of double J stents for 3-12 months.
  • Post-removal follow-up (5-36 months) revealed symptom cessation, hydronephrosis remission, and enhanced renal function.
  • Excretory urography and pyelography confirmed stricture improvement in 25 ureters.

Impact:

  • This study suggests persistent dilatation with double J stents as a primary treatment option for PUJ stricture.

  • The technique offers a less invasive alternative with positive clinical outcomes.
  • Improved renal function and reduced hydronephrosis indicate successful management of the obstruction.
