A comparative study between Snodgrass versus Mathieu with dartos flap urethroplasty for distal hypospadias repair

Abstract

Objective The aim of this study was to compare between Snodgrass and modified Mathieu procedures regarding the complications rates and the operative time. Background Hypospadias is the presence of abnormal meatal opening along the ventral aspect of the penile shaft or into the perineum. Surgical management of hypospadias abnormality has challenged and perplexed surgeons. Patients and methods From April 2015 to December 2016, eligible boys were randomly assigned with equal probability to undergo one of the two techniques of hypospadias repair. The study included 40 children experiencing anterior distal shaft hypospadias. Surgeries were performed by a single surgeon. Patients were followed up after discharge. Results Mean age for the patients was 23 months, and the mean operative time varied from 70 min for Snodgrass to 100 min for Mathieu (P = 0.170). Success rate was 17 (85%) of 20 for the Snodgrass and 18 (90%) of 20 for modified Mathieu (P = 0.072). Complication rates in the form of urethrocutaneous fistula and meatal stenosis were the commonest, being 15% in Snodgrass and 10% in modified Mathieu repair. No statistically significant difference was found between tubularized incised plate and modified Mathieu procedure regarding complications (P = 0.721). Conclusion Snodgrass and modified Mathieu repair were safe, and the choice of one of the techniques will depend on the surgeon's decision.
