[Surgical treatment of vesico-ureteral reflux: comparison between sub-ureteric injection of Polytef and the Cohen technique]

Abstract

40 patients who need surgical treatment for their vesico-ureteral reflux have been operated between 1989 and 1992; 26 of them have got the subureteric injection of Polytef (S.U.I.P.) and 14 the neo-uretero-cystostomy (N.U.C.) of Cohen. Even the N.U.C. of Cohen keeps the best results in our experience with only one stenosis on 28 operated ureters (3%), the S.U.I.P. is still an excellent technic because of its simplicity, low morbidity with 90% rate of success. This rate seems stable after a recoil of 19 +/- 13 months. Research must focus on finding a new substance to replace the Polytef and stop the fear of its particles migration found experimentally in animals.
