The authors reported their experience using detubularized ileal pouch and Benchekroun hydraulic valve. They obtain continence in all patients, and antireflux in only 12 of them. 30 patients were operated according to this technique from January 1986 to December 1992. The main indication was represented by vesical tumors, treated by cystoprostatectomy. 90% of the patients operated this way are continent, when 10% were reoperated to achieve continence. They point out in the follow-up the steady state of renal function, and radiologically, the improvement or at least the stabilization of pyelo-ureteral dilatation, and the absence of ureteral reflux, especially when antireflux system was performed using Benchekroun hydraulic valve.
