Managing hypospadias failure: A comprehensive review of strategies and outcomes.

Introduction: Hypospadias surgery has a failure rate ranging from 10% for distal cases to over 30% for proximal cases. However, real-world outcomes may be worse, as some complications emerge late in puberty or are underreported. The expectations for surgical success have evolved, shifting from basic urinary and sexual functionality to achieving a normal penile appearance. Bias in research favors retrospective studies with short follow-ups, and qualitative research remains scarce. This review describes complications following hypospadias surgery, their management, and prognosis.

Methodology: A non-systematic critical review of existing literature on hypospadias complications and surgical management was conducted.

Results: Common complications include urethrocutaneous fistulae (UCF), glans dehiscence (GD), urethral stenosis (US), urethral diverticulae (UD), urine spraying, and recurrent curvature (RC). UCF is the most frequently reported complication, treated through multilayer closure with vascularized flap coverage. GD occurs more frequently in proximal hypospadias, requiring glans reformatting and tissue augmentation. US often manifests as meatal stenosis or neourethral strictures, requiring meatoplasty or staged urethroplasty. UD arises from loose urethral segments subjected to high urinary flow resistance and is managed via excision or remodeling. Urine spraying is linked to insufficient glans fusion or meatal irregularities, sometimes requiring surgical correction. RC is a significant complication impacting sexual function, requiring individualized correction through dorsal plication or ventral lengthening.

Conclusion: Hypospadias complications require individualized assessment and surgical planning. Late complications, often underrecognized, should be considered in long-term follow-up. Proper surgical technique selection and postoperative evaluation help mitigate recurrence and improve patient outcomes.
