We analyzed 237 patients who underwent total cystectomy with ileal conduit urinary diversion or cutaneous ureterostomy at the Center for Adult Diseases, Osaka. One-hundred and eighty-eight patients underwent ileal conduit diversion and 49 patients underwent cutaneous ureterostomy. No patient died within 30 days after the operation, but two patients who underwent ileal conduit diversion died of postoperative complications within 2 months. Early complications occurred in 94 patients (50%) in the ileal conduit group and in 18 patients (37%) in the ureterostomy group. Late complications occurred in 85 patients (45%) in the ileal conduit group and in 23 patients (47%) in the ureterostomy group. Frequent early complications in the ileal conduit group were wound infection (29%), and intestinal complications (13%) which included ileus and upper urinary tract complications (12%). The most frequent late complications were stomal complications (26%) which included peristomal dermatitis stomal stenosis, parastomal hernia, and stomal prolapse, and upper urinary tract complications which were noted in 27 patients (14%).
