Abstract:
From May 1991 to December 1993, 30 male bladder cancer patients with 34 to 68 years old age (mean age 52.4 years) underwent bladder replacement with the ileocolic neobladder. A divided segment of ileum and colon was used to create a neobladder after radical cystectomy with a cecourethral anastomosis to provide volitional voiding with continence. Urodynamic studies were followed up 3, 6, l2 and 18 months postoperatively. The mean maximal reservoir capacity was 420+/-87.7, 553+/-65.3, 565+/-60.3, 563+/-53.5ml, mean maximal reservoir pressure was 33.2+/-7.5, 24.2+/-6.1, 24.0+/-5.9, 23.1+/-6.3cmH2O, mean maximal urethral closure pressure was 57.9+/-9.5, 61.3+/-7.6, 61.0+/-7.3, 61.5+/-6.9cmH2O, maximal flow rate was 23.2+/-7.2, 24.3+/-5.8, 24.0+/-6.1, 24.1+/-5.4ml/s and residual urine was 40.0+/-10.3, 35.0+/-7.8, 24.0+/-6.1, 24.1+/-5.4ml/s. The daytime continence rate was 100% and the nighttime continence rate was 93% at 6 months postoperatively. With its very good functional results and its ease of performance, ileocolic neobladder may be one of the ideal urinary diversion for bladder substitution after radical cystectomy.
