Abstract
Patients (39) treated by cystectomy and ileal loop diversion for carcinoma of bladder were divided into the following 3 groups: cystectomy alone; cystectomy combined with preoperative irradiation; salvage cystectomy following radical radiotherapy. The postoperative complications and subsequent function of the ureteroileal segment of the urinary diversion were compared in the 3 groups. Those having primary cystectomy had the fewest complications and best long-term function; those having surgery within 12 mo. of radical radiotherapy had the highest incidence of ureteroileal obstruction. The possible etiology is discussed.
