Modified Byars’ flaps for securing skin closure in proximal and mid-penile hypospadias

Abstract

Objective: The objective of this study was to describe a modification for skin closure combined with tubularized incised plate (TIP) urethroplasty in the repair of proximal and mid-penile hypospadias. Patients and methods: The study included 47 patients with nondistal hypospadias who underwent a primary TIP procedure from September 2007 to May 2010. Meatal position was mid-shaft (n = 20), penoscrotal (n = 20), and scrotal (n = 7). The patients in the study were divided into two groups according to a modification in the technique of skin closure, which involved incising the prepuce vertically into two halves, then harvesting the dartos flap for covering the repair from one half, leaving the other preputial half to reconstruct the ventral skin without compromising its blood supply. Results: In the standard procedure (n = 19 patients), complications included glanular dehiscence (10.5%), glanular fistula (5%), urethrocutaneous fistula (10.5%), and skin complications (21%). In the modified procedure (n = 28 patients), complications included glanular dehiscence (7%) and glanular fistula (3.6%), but no skin complications or urethrocutaneous fistulae occurred. Conclusion: The modified Byars’ flaps is a useful alternative for skin closure during proximal and mid-shaft TIP urethroplasty, with fewer complications and acceptable cosmetic outcome. © 2011, SAGE Publications.
