Pedicle patch urethroplasty offers a single-stage repair for hypospadias. This vascularised graft technique showed an 18% fistula rate in primary repairs, with few other complications.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Reconstructive Surgery

Background:

  • Hypospadias repair presents surgical challenges.
  • Alternative techniques are explored for optimal outcomes.
  • Vascularised grafts offer potential benefits in reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of pedicle patch urethroplasty for hypospadias repair.
  • To assess complication rates, particularly fistula formation.
  • To determine suitability for specific patient cohorts.

Main Methods:

  • A retrospective review of 38 primary hypospadias repairs using pedicle patch urethroplasty.
  • Analysis of complication rates over a 7-year period.
  • Inclusion criteria focused on moderately severe hypospadias with preserved urethral plate.

Main Results:

  • The pedicle patch urethroplasty was employed in 38 primary hypospadias repairs.
  • A fistula rate of 18% was observed in the 34 reviewed patients.
  • Few other significant complications were reported, indicating a generally safe procedure.

Conclusions:

  • Pedicle patch urethroplasty is a viable single-stage alternative for hypospadias repair.
  • It is recommended for cases where the urethral plate is preserved and penile straightening is achievable.
  • This technique is suitable for patients not candidates for meatal-based flaps.
