[Ureterovesical reimplantation. A technic derived from Lich and Gregoir's procedure]

Fifty-five uretero-neocystostomies were carried out using a technique derived from the Lich-Gregoir technique. Tightness is ensured anastomosis and burying over the vesical dome, with minimal vesical opening; the anti-reflux system is effective. Urinary complication of this ureter transplantation method are now rare, in our series, only two complications due to necrosis of the ureteral segment were observed. This technique could be used in all obliterations of the ureter, whether accidental or by necessity, located near the bladder.
