Proximal hypospadias, including penoscrotal and scrotal types, represent about 20% of all hypospadias cases and present surgical challenges in achieving a straight, functional, and cosmetically favorable penis. This research compares two surgical techniques used in two-stage repair of primary proximal penile hypospadias. The study aims to address the ongoing debate about the best method to substitute the urethral plate in these complex cases. The trial evaluates outcomes of two different surgical approaches: the inner preputial graft and the transverse preputial island flap, both used in the first stage of a two-stage repair for proximal penile hypospadias. These methods are compared to see which yields better results in terms of complications and success rates. The inner preputial graft is noted for its versatility, especially in cases with limited healthy local skin, while the flap method offers a reliable blood supply potentially reducing strictures or contractures. Participants will undergo surgery with one of the two techniques and be closely monitored for complications and outcomes. Researchers will measure the rate of complications six months after the end of treatment to evaluate the success of each method. The study includes careful follow-up to assess both functional and cosmetic results, with the total participation spanning the treatment and post-treatment monitoring periods.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Duration - Duration of surgical treatment period
Participants undergo a two-stage surgical repair for proximal penile hypospadias using either an inner preputial graft or a transverse preputial island flap in the first stage, followed by immediate post-operative care.
