Comparison of Cohen and Lich-Gregoir ureteral reimplantation in the surgical management of primary unilateral vesicoureteral reflux in children

Abstract

Intravesical and extravesical ureteroneocystostomy methods are equally successful and feasible in the treatment of primary unilateral VUR. The Cohen technique is associated with a longer and more painful hospital stay, gross hematuria, and longer operative time, compared to the Lich-Gregoir technique.
