Ureterointestinal anastomosis in orthotopic neobladders.

Objective: This study reports our experience with a ureteroileal reimplantation technique based on the Leadbetter-Clarke method, which is used for orthotopic neo-bladders, constructed preferably with the Camey ii technique. Methods: We carried out 114 ureteroileal reimplantations using this technique in 58 patients undergoing radical cystectomy and orthotopic neobladder reconstruction. The incidence of neobladder-ureteral stenosis and reflux were analyzed during the follow-up. Results: During the mean follow-up of 31 months, the incidence of stenosis was 2.6% (3 ureteroileal implants, including 1 case of neoplastic stenosis). The incidence of slight-to-moderate reflux was 9.6% but did not cause any deterioration in renal function or an increased incidence of reflux-related pyelonephritis. Conclusion: This technique provided good functional results and a low incidence of complications, and may be recommended as a valid alternative to standard methods of creating ureterovesical anastomosis.
