Abstract
Despite the success of endopyelotomy, many points are still being debated. Ureteroscopic retrograde endopyelotomy was carried out in 49 adult patients with 39 available for long-term follow-up. Prestinting facilitated instrument passage and reduces morbidity. The average operating time was 90.2 minutes. Two patients underwent elective nephrectomy for poorly functioning kidneys that did not improve after treatment, and one patient underwent urgent nephrectomy for bleeding 26 days postoperatively. Improvement in drainage was documented in the successful cases. The authors consider ureteroscopic endopyelotomy the first-line approach for most cases of ureteropelvic junction obstruction.
