[Ureteral replacement with ileal graft with anti-reflux valve]

The authors describe an ureteroileoplasty with a new anti-refluxing technique. A subtotal ureteroplasty is carried out, anti-refluxing proceeding is made. This one is based on Benchekroun's hydraulic valve principle. A transversal ileostomy is carried out 8 cm below the uretero-ileal anastomosis, which is invaginated and fixed to the proximal layer of the ileostomy with Dexon 3/0, the ileostomy is then closed using Dexon 2/0. The hydraulic valve may then ensure anti-reflux.
