A preliminary report of 3 cases of carcinoma bladder is presented in whom, after radical cystoprostatectomy, a low pressure neobladder is created from detubularised pelvic colon, with subsequent colo-urethral anastomosis. In selected cases, this is a feasible procedure with good patient acceptance as the normal body image is maintained. Also the low pressure neobladder ensures protection to the upper urinary tract from backpressure damage.
