Ileal neobladder reconstruction after radical cystoprostatectomy.
To improve the outcome and patient acceptance of bladder substitution, five male patients underwent O-shaped ileal neobladder reconstruction, after radical cystoprostatectomy for invasive bladder cancer, with a mean follow-up of 11 months. With only 40 cm of ileal segment, an O-shaped neobladder was constructed after complete detubularization. Bilateral ureters were implanted using the Le Duc-Camey method. Six months after operation, all patients were totally continent during the day time, and one patient suffered from mild incontinence at night, which could be overcome by waking to void once or twice. The satisfactory continence levels are in agreement with a urodynamic study of the neobladder which showed a low pressure, high-capacity (mean, 456 mL) reservoir in the cystometric tracings. The mean maximal flow rate was 22.2 mL/sec, the mean residual urine was minimal (10 to 20 mL), the mean maximal urethral closing pressure was 74.4 cm H2O and the mean functional profile length was 2.9 cm. All renal units do not have neovesico-ureteral reflux. Two patients showed unilateral hydronephrosis which subsided later, one patient sustained bilateral hydronephrosis and died of jejunal perforation five months postoperatively. There were few perioperative complications and no patient expressed regret at having undergone the procedure. We consider bladder substitution to be the treatment of choice in male patients requiring radical cystoprostatectomy.
