title: [Variant of vesico-ureteral reflux surgical treatment in children].
abstract: Cowen's operation has been performed on 77 ureters in 52 children with vesicoureteral reflux of degree II-IV. Positive results were observed in 97.7% of the operated children. These figures rose to 100% after Cowen's operation in original modification proposed by the authors in 1995. A total of 12 children (18 ureters) were treated according to this modification which, in pronounced lateral ectopy of the refluxing ostium ureteris, stipulates establishment of the cross-sectional tunnel not along the interureteral ligament, but at the acute vertical angle. The ostium of the reimplanted ureter was located under the contralateral one within the Lieutaud's triangle. In bilateral operation, one of the submucous tunnels is located along the upper line of the Lieutaud's triangle, the lower one being at the acute vertical angle. The above modification is pathogenetically sound and provides the unity of the anatomomorphological structures of the vesicoureteral segment.
