Fibrin Glue versus Dorsal Dartos Flap in Snodgrass Operation: A randomized clinical trial for comparison of the outcomes

Abstract

Hypospadias (HS) is a common congenital defect that is present in 1/300 newborn children (0.3%). The goals of primary hypospadias repair include straightening the curvature of the penis, extending the meatus to the glans tip, and revising the abnormal prepuce by either circumcision or foreskin reconstruction to allow satisfactory cosmetic and functional results. The tubularized incised plate procedure of Snodgrass is currently one of the most popular procedures in the surgical repair of hypospadias. Urethrocutaneous fistula formation has long plagued those who perform hypospadias surgery. One of the most important factors in reducing the incidence of fistula in hypospadias repair was the introduction of a protective intermediate layer between the neourethra and the skin layer. The protective intermediate layer includes the de-epithelialized skin, tunica vaginalis, dorsal dartos flap, dartos flap from the scrotum, external spermatic fascia flap & spongiosal tissue. Biosurgical preparations designed to promote surgical hemostasis and tissue adhesion are being increasingly
