  • Title: Treatment of transplant ureteral stenosis with endoureterotomy.
    Author: Erturk E, Burzon DT, Waldman D.
    Journal: J Urol; 1999 Feb; 161(2):412-4. PubMed ID: 9915414.
    Abstract:
    PURPOSE: The safety and efficacy of treating renal transplant ureteral stenosis with the Acucise endoureterotomy catheter are described. MATERIALS AND METHODS: We treated 4 women and 3 men 31 to 63 years old (mean age 45) with Acucise endoureterotomy for distal (6) and proximal (1) ureteral stenosis. Diagnosis was based on increasing serum creatinine and hydronephrosis on ultrasound, and confirmed by antegrade nephrostogram. One patient had recurrence and, therefore, 8 procedures were performed. Mean followup was 13 months (range 7 to 21). RESULTS: Technical success was 100%. One patient had a recurrent stricture and was successfully re-treated. Of the patients 3 had chronic rejection and renal failure, and 4 had stable renal function. All ureters remain patent to date. CONCLUSIONS: Treatment of short ureteral stenosis with Acucise endoureterotomy in a renal transplant is safe and effective. Furthermore, it can be performed in an ambulatory setting with minimal morbidity. This procedure should be considered as the initial approach for distal ureteral stenosis in the transplanted kidney.
