[The results of the diversion of urine into a large-intestine reservoir].

Cystectomy for bladder cancer with derivation of the urine into the colon was performed in 35 patients (30 males and 5 females). Postoperative lethality was 11.4% (4 patients). The best outcomes in cases of partial and/or complete failure of the ileocecal valve were obtained when forming the invaginate in the stomal ileum. Examination following the surgery was conducted in 31 patients. Of them, preoperative passage from the upper urinary tracts was impaired in 22 (71%) because of the tumor spread into the ostium urethritis. Postoperative defect from the upper urinary tracts was recorded in 7 (22.6%) patients, while normal function of the kidney was registered in 24 out of 31 patients (77.4%). A complete retention of the urine was achieved in 27 of 31 patients (87.1%). With time, the capacity of the colon reservoir increased up to 750 +/- 57.9 ml to the end of the second postoperative year. The right part of the colon, cecum or ascending colon as well as the proximal third of the transverse colon as the reservoir served satisfactorily.
