Summary
The Snodgrass urethroplasty technique, adapted with a dartos flap, effectively repairs hypospadias in boys, achieving good cosmetic and functional outcomes with a low complication rate.
Area of Science:
- Pediatric Urology
- Surgical Techniques
- Congenital Abnormalities
Background:
- Hypospadias repair is a common pediatric urological procedure.
- The Snodgrass technique is a widely used method for hypospadias correction.
- Adaptation of surgical techniques is crucial for improving outcomes.
Purpose of the Study:
- To present the authors' experience adapting the Snodgrass technique for primary hypospadias repair.
- To evaluate an alternative method for creating a dartos flap barrier for neourethral covering.
- To assess the efficacy and safety of this modified Snodgrass technique.
Main Methods:
- A cohort of 24 boys (14 months to 9 years) underwent modified Snodgrass urethroplasty.
- The study involved adaptation of the Snodgrass technique with a dartos flap.
- Postoperative management included urethral stenting and suprapubic diversion.
Main Results:
- All patients achieved a neourethra with a glanular meatus.
- A 12.5% urethrocutaneous fistula rate was observed.
- No urethral strictures were reported; one case of meatal stenosis was successfully treated.
Conclusions:
- The adapted Snodgrass urethroplasty offers satisfactory cosmetic and functional results.
- This technique demonstrates versatility in repairing various hypospadias types.
- The modified approach provides a reliable option for primary hypospadias repair.
