Effect of Adding Byar's Flap to Double Dartos Coverage in TIP Urethroplasty for Distal Hypospadias: A Randomized Trial
Sponsor: Javaid Afridi
Summary
This randomized controlled trial evaluates the effect of adding Byar's flap in combination with double dartos flap coverage during tubularized incised plate (TIP) urethroplasty in children with distal hypospadias. The study compares surgical outcomes between two techniques: TIP urethroplasty with double dartos coverage alone versus TIP urethroplasty with double dartos plus Byar's flap reinforcement. The primary outcome is the rate of postoperative complications, including urethrocutaneous fistula, glans dehiscence, meatal stenosis, and wound infection. Secondary outcomes include cosmetic outcome assessment and functional results using validated scoring systems. Patients diagnosed with distal penile hypospadias were randomly assigned to either surgical group. All procedures were performed by an experienced pediatric surgeon under standardized operative conditions. Follow-up assessments were conducted over a 6-month postoperative period to evaluate early and intermediate surgical outcomes. The objective of this study is to determine whether the addition of Byar's flap provides superior surgical outcomes compared to standard double dartos coverage in TIP urethroplasty.

Interventions
Double Dartos Flap Coverage
A vascularized dartos fascia flap is harvested and used as a second-layer coverage over the neourethra following tubularized incised plate (TIP) urethroplasty to reduce postoperative complications such as urethrocutaneous fistula.
Byar's Flap + Double Dartos Flap
Byar's flaps are created from preputial skin and combined with double dartos flap coverage to reinforce the neourethral repair after tubularized incised plate (TIP) urethroplasty in distal hypospadias.
