Is this trial a fit for you?

Likely a good fit

Ideal candidates are male patients aged 6 months to 18 years with distal hypospadias undergoing primary repair, with urethral plate greater than 8 mm and glanular width at least 14 mm.

Probably not a fit

Patients with coronal or glanular hypospadias, severe chordee, associated disorders of sexual development, or uncontrolled bleeding disorders may not benefit from this comparison.

What this trial studies

This interventional study compares two microsurgical techniques—single dartos flap and double dartos flap—in distal hypospadias repair. It enrolls male patients aged 6 months to 18 years undergoing primary (first-time) surgery with specific urethral plate and glanular measurements. Outcomes focus on surgical success and functional results, including the rate of complications such as fistula formation. Urethrocutaneous fistula remains a common challenge, and this study investigates whether a double flap provides superior protection. The trial is conducted at Tanta University in Egypt, led by the lead sponsor, with no listed collaborators.

Why it matters

Potential benefit: If successful, the double dartos flap technique could reduce postoperative fistula rates and improve overall surgical outcomes for distal hypospadias.

How similar studies have gone: Previous research has explored dartos flap techniques, but evidence on the superiority of double over single flaps remains mixed and not definitive.
