Single-Stage Double-Face Preputial Island Flap versus Two-Stage Byars' Flap Repair for Severe Proximal Hypospadias: A Prospective Randomized Study

Topic overview

Key takeaways

• Both single-stage DFPIF and two-stage Byars' flap achieved comparable functional and cosmetic outcomes in severe proximal hypospadias repair.
• Double-face preputial island flap showed significantly higher partial wound dehiscence rates compared to Byars' flap (p=0.041).
• Single-stage DFPIF may reduce procedure number and costs, but wound healing complications require careful consideration in technique selection.
• HOSE scores and parental satisfaction were equivalent between techniques at 12-month follow-up despite different complication profiles.
• Blinded outcome assessment and randomized design provide Level 1 evidence for comparing these hypospadias repair techniques in resource-limited settings.
