Snodgraft versus Snodgrass repair of primary distal hypospadias comparative study.

Abstract

Hypospadias is defined as an incomplete virilization of the genital tubercle, leading to an ectopic opening of the urethra on the ventral aspect of the penis, anywhere from the glans to the perineum. The international incidence is about 1:250 to 1:300 live male infant births. Surgical repair is the mainstream of therapy and one of the most common procedures performed by pediatric urologists. The aim of hypospadias repair is to achieve normal urinary and sexual function with good cosmetic result and self-confidence of the child. There’s no definitive cause for hypospadias. There are many factors that may account for it as testosterone deficiency, maternal use of oral contraceptives during early pregnancy, maternal exposure to antiepileptic drugs, intrauterine growth retardation and low birth weight, twins and advanced maternal age. The classification of the hypospadias has changed throughout time. The most commonly used classification divides hypospadias as follows: distal, midshaft, proximal. Distal or anterior hypospadias is the most common variant of the disease representing 60-70% of cases. During the past two decades, we have witnessed considerable improvement in the functional and cosmetic results of hypospadias repair. This has been the result of a multitude of factors, including refinement of
