Platelet-rich fibrin versus grafted TIP repair for distal hypospadias

Official title: A Multicenter Randomized Controlled Trial Comparing Fibrin-Enhanced Tubularized Incised Plate (F-TIP) and Grafted Tubularized Incised Plate (G-TIP) Urethroplasty in Distal Hypospadias With Unfavorable Urethral Plates

Run by National Children's Medical Center, Uzbekistan · NCT07319780 · Data updated 2026-11-12

This trial tests whether applying a boy's own platelet-rich fibrin during TIP repair leads to fewer complications than grafted TIP in boys aged 6 months to 7 years with distal hypospadias and an unfavorable urethral plate.

Is this trial a fit for you?

Likely a good fit

Boys aged 6 months to 84 months with primary or redo distal hypospadias, an unfavorable urethral plate, penile curvature under 45 degrees after degloving, and who are candidates for TIP urethroplasty.

Probably not a fit

Children with severe penile curvature requiring urethral plate transection, previous graft-based urethroplasty, disorders of sex development, active infection, or known bleeding/platelet disorders are unlikely to benefit or be eligible.

What this trial studies

This is a prospective, multicenter, single-blinded randomized controlled comparison of fibrin-enhanced TIP (F-TIP) using autologous platelet-rich fibrin (PRF) versus grafted TIP (G-TIP) in children with distal hypospadias and an unfavorable urethral plate. Boys aged 6 to 84 months with primary or redo distal hypospadias and penile curvature under 45 degrees are randomized 1:1 to receive intraoperative PRF applied to the incised urethral plate or standard graft augmentation without PRF. PRF is prepared from the patient’s peripheral blood using a standardized centrifugation protocol and applied before tubularization. Participants are followed postoperatively to record surgical complications (such as urethrocutaneous fistula and meatal stenosis), functional outcomes, and cosmetic results using predefined outcome measures.

Why it matters

Potential benefit: If successful, using autologous PRF could reduce rates of fistula and meatal stenosis and improve healing and cosmetic and functional outcomes after TIP repair.

How similar studies have gone: Grafted TIP is an established technique, and small observational studies of platelet-rich fibrin or other blood-derived products suggest improved wound healing, but randomized pediatric evidence for PRF in hypospadias repair is limited.
