[The surgical treatment of vesicoureteral reflux in kidney duplication in children].

The examination of 41 patients with a complete renal duplication and vesicoureteral reflux (VUR) into 57 ureters has shown a direct dependence of morphological immaturity of the parenchyma of the double kidney segment and functional insufficiency of the obturative apparatus of the ostium of the corresponding ureter on the degree of its dislocation corresponding to the normal localization on the inner surface of the urinary bladder. For patients with marked lateral position of the main ostium of the organ saving operations are senseless because of high degree of VUR and deep dysplasia of the renal tissue. In cases with moderate lateralization of the ureter ostium it is expedient to fulfil such antireflux interventions as Lich-Gregoir operations in a "single block" or the endoscopic correction of the ostium with a synthetic medical siloxan rubber or polyacrylamide gel "Interfall".
