[The causes of mortality following cystectomy for bladder tumor].

The analysis of the treatment results is given for 183 patients with bladder cancer following cystectomy under various methods of urine derivation. Ureterocutaneostomy, Brickers operation, ureteral implantation into an isolated segment of the sigmoid, ureteral implantation into the colonic reservoir with controlled evacuation, radical cystectomy with ureteral implantation into an isolated rectal bladder with formation of sigmostoma, ureterosigmoanastomosis were performed in 94, 15, 10, 35, 12 and 17 patients, respectively. As shown by the follow-up available for 151 patients, 55 patients died of the tumor progression, 22 of renal complications, 11 of other causes. Within 2 postoperative years the disease progression and renal failure caused death in 65 (73.9%) out of 88 patients. The least lethality due to renal failure (3.2%) was recorded in patients with colonic reservoir.
