Failed hypospadias repair: An algorithm for secondary reconstruction using remaining local tissue

Area of Science:

• Pediatric Urology
• Reconstructive Surgery
• Hypospadias Research

Background:

• Salvage hypospadias surgery addresses failed primary reconstructions.
• Multiple treatment strategies exist with varying outcomes.
• Local tissue availability is crucial for secondary repair success.

Purpose of the Study:

• Evaluate a primary hypospadias repair algorithm in secondary cases.
• Assess the efficacy of the algorithm when local tissue is present.
• Determine optimal salvage strategies based on curvature severity.

Main Methods:

• Applied a treatment algorithm to 36 patients with prior failed hypospadias repairs (109 procedures total).
• Classified patients based on ventral curvature and meatus location.
• Utilized local skin flaps for one-stage repairs (no/minimal curvature) or two-stage repairs (marked curvature/proximal meatus) using Byars' technique.

Main Results:

• 12/36 patients achieved satisfactory results in one procedure using local flaps (no curvature).
• 6/36 patients underwent one-stage repair for moderate curvature.
• 18/36 patients required two-stage repair for severe curvature or proximal meatus.
• Successful reconstruction achieved in 35/36 patients after a median of two salvage procedures.

Conclusions:

• Underestimation of ventral curvature is a common cause of hypospadias repair failure.
• Reevaluation of curvature is critical for successful salvage surgery.
• One-stage salvage is feasible for minimal curvature; two-stage repair is preferred for significant curvature and complex defects.
