Evaluation of double faced transverse preputial (onlay) island flap for hypospadias repair in pediatrics: a randomized controlled study.

Background: The preputial onlay island flap technique has been popularized for hypospadias repair as a result of offering a consistent combination of acceptable functional and cosmetic results. Like other techniques, urethrocutaneous fistulae and stricture continues to be the most common complications, in addition to other complications, which could be attributed to the compromise in flaps vascularity. Some authors describe a technique that resolves some of these problems by combining the unique benefits of the double faced preputial flaps.
