Journal of Evolution of Medical and Dental Sciences 2014; Vol. 3, Issue 32, August 04; Page: 8818-8824, DOI: 10.14260/jemds/2014/3129 ABSTRACT: AIM: To study the comparative result of hypospadias repair by dividing the patients in two groups (a) hypospadias repair with waterproofing layer by one of the technique of hypospadias repair.(b) hypospadias repair without waterproofing, and evaluate the complication rates between these two groups especially in reference to incidence of urethrocutaneous fistula. MATERIAL AND METHODS: A prospective study done in the regional institute of surgery and pediatrics, M.L.B. Medical College, Jhansi during 2010 to 2013 with complain of location of urethral meatus on undersurface of penis i.e. hypospadias on 18 cases. RESULT: In the present study, most of our cases (83.33) were of less than 8 years of age. Most common type was middle hypospadias (50%), followed by proximal (27.77%) and distal (22.22%). Chordee was present in 66.66% of our cases.11.11% cases had penile torsion in pre-operative period. Asopa technique was used in cases with significant chordee and Snodgrass technique used in cases without significant chordee. Urethral plate was well formed and grooved in 66.66% cases, shallow in 27.77% cases and distorted in 5.55% cases. Waterproofing of neourethra was done in 55.55% cases, 44.44% cases were without Water proofing layer. Without Water proofing group had better cosmetic results(87.5%) than with Water proofing (70%) but more chances of metal stenosis and skin flap necrosis that leads to urethrocutaneous fistula formation. So Waterproofing decrease the chances of metal stenosis and skin flap necrosis with poor cosmetic results. KEYWORDS: Hypospadias, Water proofing layer, Single stage repair, Urethrocutaneus fistula. INTRODUCTION: Since first attempt for hypospadias repair by Alexandrian Surgeons Heliodorus and Antylluss during first century A D, the imagination and creativity of surgeons has continuously being challenged by this problem. 1 The goal of modern hypospadias repair is to achieve functionally, as well as cosmetically normal looking glans, meatus and phallus. 2 Hypospadias repair is more prone for complications. One stage repair seems ideal and attractive but carries its own limitation and high complication rates. The long term results are also disappointing. 3 The quality of the end result is of greater relevance psychologically than the number of operations with which it is achieved considering the unrivalled versatility, applicability, simplicity and excellent results. Hypospadias in males is an association of three anomalies of penis: 1. An abnormal ventral opening of urethral meatus from ventral aspect of glans penis to the perineum. 2. An abnormal ventral curvature of penis (chordee). 3. An abnormal distribution of fore skin dorsal hood. Second and third characters are not present in all cases. It is usually associated with meatal stenosis and also with cryptorchidism incidence is approximately 1 in 250 male newborns. The role of
