[Percutaneous transluminal dilatation of benign ureteral stenoses].
Ten benign ureteral strictures, in nine patients, were dilated with balloon catheter in conjunction with percutaneous nephrostomy. One patient had bilateral stenosis. The strictures followed ureteroileostomy (3 cases), uretero-uretero anastomosis (2 cases), ureteroneocystostomy (1 case), radical hysterectomy with associated ureteral fistula (1 case), post-surgical ureteral fistula (1 case) and benign long-standing stricture of unknown origin (1 case). Nine out of ten strictures were successfully dilated with disappearance of hydronephrosis. One patient underwent surgical correction of the stenosis. Dilation proved to be unsuccessful. The follow-up goes from 2 to 30 months and there is no evidence of obstruction.
