Fibrin-Enhanced TIP Versus Grafted TIP Urethroplasty in Distal Hypospadias
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

Conditions
Summary
Hypospadias is a common congenital condition in boys in which the opening of the urethra is located on the underside of the penis. Distal hypospadias is the most common form and is usually treated surgically using tubularized incised plate (TIP) urethroplasty. In boys with an unfavorable urethral plate, graft-augmented techniques (G-TIP) are often used; however, postoperative complications such as urethrocutaneous fistula and narrowing of the urethral opening (meatal stenosis) may still occur. Platelet-rich fibrin (PRF) is a biological material obtained from the patient's own blood that contains natural growth factors and may help improve tissue healing. This study aims to evaluate whether the use of PRF during surgery can reduce postoperative complications and improve surgical outcomes in children undergoing hypospadias repair.
