Abstract
We reviewed the records of 31 patients treated during the last 5 years for ureteral stricture disease. The causes of stricture formation included ureteroenteral anastomoses (23 percent), open ureterolithotomy (19 percent), ureteroscopy (19 percent), other urological procedures (16 percent), general surgical and gynecological procedures (13 percent) and miscellaneous causes (7 percent). Of the patients 24 were managed initially with antegrade or retrograde balloon dilation or stenting and favorable outcomes were achieved in 12 (50 percent), with a mean followup of 13 months. Of the 12 patients who failed endourological management 6 subsequently underwent open repair with a 100 percent success rate. The remaining 7 patients underwent an open operation as the initial management and successful results were achieved in 6. The over-all rate of successful management of ureteral stricture disease using endoscopic and open surgical techniques was 77 percent. A total of 7 patients (23 percent) failed attempts at intervention: 5 showed evidence of decreasing renal function and 2 required nephrectomy.
