Incidence of urethrocutaneous fistula after distal and midshaft hypospadias repair does not differ among patients treated with or without a protective second-layer: single tertiary centre experience
Topic overview
This retrospective study of 425 pediatric hypospadias repairs found no significant difference in urethrocutaneous fistula rates between single-layer urethroplasty (7.3%) and repair with a periurethral tissue second layer (6.7%). The findings suggest that meticulous urethral suturing technique may be more critical than tissue interposition for preventing fistula formation.
Key takeaways
- Urethrocutaneous fistula occurred in 7% of cases overall, with no significant difference between single-layer (7.3%) vs. two-layer repair (6.7%).
- A meticulous urethral suture technique is more critical than adding a second tissue layer for preventing fistula formation.
- Periurethral tissue provides effective coverage when a second layer is used, requiring minimal additional dissection.
- 37% of fistulas were associated with meatal stenosis, suggesting shared pathophysiology or technical factors.
- Single-layer urethroplasty may be a viable option for distal/midshaft hypospadias, potentially simplifying the procedure without increasing complications.
