Description

We report our experience with the endourological treatment of 4 patients with 5 benign ureteroileal anastomotic strictures after ileal conduit urinary diversion. The treatment was successful in 4 of the 5 renal units without restenosis with a mean follow up of 10 months. The strictures were dilated by ureteral dilators and/or balloon dilation catheters using guide wires through percutaneous nephrostomies in an antegrade fashion. A 9 or 12 Fr. percutaneous splint catheter or a 12 Fr. double pig tail catheter was placed for 3-8 weeks after a successful dilation. Two renal units underwent repeated dilations. In 1 renal unit, a guide wire was hardly passed through the stricture and the treatment was unsuccessful. No serious complications were encountered. Percutaneous endourological managements of ureteroileal anastomotic strictures seemed to be quite versatile techniques which should be tried as the initial approach in many cases.
