Ureteropelvic invagination procedure for endopyelotomy (Gelet technique): review of 51 consecutive cases.
Between 1990 and 1995, we performed 51 endopyelotomies on 38 cases of primary and 13 of secondary obstruction of the ureteropelvic junction (UPJ) using the ureteropelvic invagination technique. Of the 51 patients in the series, 49 have been followed for a minimum of 3 months postoperatively (mean follow-up 16 months). Overall, success was achieved in 38 (77.5%). Endoscopic endopyelotomy was successful in 11 of 13 cases (84.5%) with secondary strictures. When the technique was used for the treatment of primary UPJ stricture, the success rate was only 75% (27 of 36). The presence of a crossing vessel was identified as the cause of failure in five cases of primary strictures; hence, we advocate the use of angiography to identify crossing vessels preoperatively. We recommend the use of the ureteropelvic invagination technique as the first-line therapy for primary hydronephrosis in adults in the absence of a crossing vessel.
