Summary
A modified hypospadias repair, the split prepuce in situ onlay repair, shows promising results for children with coronal to mid-shaft hypospadias. This technique reduces complications and offers good cosmetic outcomes.
Area of Science:
- Pediatric Urology
- Surgical Innovation
Background:
- Hypospadias repair is a common pediatric urological procedure.
- Onlay hypospadias repair techniques aim to reconstruct the urethra and glans.
- Optimizing flap vascularity and coverage is crucial for successful outcomes.
Purpose of the Study:
- To describe a modified onlay hypospadias repair technique: split prepuce in situ onlay repair.
- To report the surgical outcomes of the first 100 patients undergoing this modified procedure.
Main Methods:
- The study included 100 boys with coronal to mid-shaft hypospadias, mean age 11 months.
- The split prepuce in situ onlay repair preserves the blood supply of the preputial flap.
- Abundant subcutaneous tissue from the flap covers neourethral suture lines.
Main Results:
- A low complication rate was observed, with only 5 reoperations needed (1 hematoma, 4 fistulas).
- No cases of meatal stenosis, urethral stricture, meatal retraction, or acquired urethral diverticulum required reoperation.
- Excellent cosmetic results were achieved in all patients.
Conclusions:
- The split prepuce in situ onlay hypospadias repair is a versatile technique for hypospadias.
- It enhances flap vascularity and provides robust coverage for the neourethra.
- This method leads to a reduced complication rate and satisfactory cosmetic results.
