Comparison of Snodgrass Tubularised Incised Plate Urethroplasty and Duckett Onlay Transverse Preputial Patch Urethroplasty for Correction of Penile Hypospadias

Abstract

Introduction: Hypospadias is defined as a condition where the urethra opens on the ventral aspect of the penis. It is commonly associated with penile curvature, usually ventral and is one of the most common genital birth defects in males. Hypospadias can be treated with numerous different surgical approaches numbering upto 200, and historically has been treated with procedures like Trans-Verse Island Flap (TVIF) on lay, Tubularised Incised-Plate (TIP), vertical preputial island flap, tubularised preputial flap, vertical preputial flap with double skin island etc. Present study was conducted to compare Snodgrass Tubularised Incised Plate Urethroplasty (TIP procedure) and Duckett Onlay Transverse Preputial Patch Urethroplasty for penile hypospadias correction. Material and Methods: Male patients between the age of 2-14 years who underwent correction of penile hypospadias by either of the two techniques viz. TIP (procedure) Urethroplasty and Duckett Onlay Transverse Preputial Patch Urethroplasty were included in the present prospective observational study after written informed consent. Results: The study was carried out with 40 patients and sorted into two groups, i.e. Snodgrass (S) and Duckett (D) group with 20 patients each. No difference was observed among study groups withregards to incidence of individual complications like urethrocutaneous fistula, stricture, or wound infection (p>0.05). However, total complication rate was marginally higher (55%) in Snodgrass’ procedure as compared to Duckett’s procedure (35%). All the cases of stricture (10%) and wound dehiscence (5%) were reported in Snodgrass group.
