Comparative study between snodgrass urethroplasty and modified snodgrass urethroplasty for distal penile hypospadias in terms of post-operative urethrocutaneous fistula formation

Background: Hypospadias is a congenital defect involving the male urethra characterized by absence of urethral meatus at its normal position. This anomaly usually associated with ventrally deficient but dorsally hooded skin. In some cases, penis curved. Surgery option for this defect. So many procedures have been developed none free from development urethrocutaneous fistula. Now-a-days, popular Snodgrass procedure widely practiced still fistula occurs. Many factors are thought to be responsible it. The most important one defective ventral penile skin which vascular and collagen tissues. To minimize these factors, dorsal preputial flap transferred (modified) reduce formation further. A comparative study was disigned determine role flap.Methods: prospective observational conducted in department pediatric surgery, Bangabandhu Sheikh Mujib medical university, Dhaka, Bangladesh since February 2017 May 2021.Results: total 40 patients distal hypospadias were included study. They divided into Group group B, 20 each. modified done B. outcome both groups determined terms formation. Seven group-A patient B results analyzed found statistically significant.Conclusions: Modified urethroplasty has better outcome.
