Endoureterotomy for treatment of ureteral strictures.

Abstract

Advances in endosurgical technology have provided the urological surgeon with an alternative to open surgery for the treatment of ureteral strictures. We report the use of an endoscopic intraureteral incision (endoureterotomy) followed by balloon calibration to treat benign ureteral strictures in 13 patients. With an average subjective and objective followup among successful endoureterotomies of 20 months (all cases 12 months or greater), the overall success rate for this procedure is 62%. Of these patients 5 also received triamcinolone injections into the stricture bed following incision and dilation. This method appeared to influence favorably subsequent ureteral patency. The only operative complication was a urinoma, which resolved without intervention. Endoureterotomy appears to be a safe and reasonably effective modality for the treatment of ureteral stricture disease.
