(Background) We previously performed one-stage urethroplasy with OUPF IV in 17 patients with proximal hypospadias and experienced meatal stenosis in 3 and meatal regression in 2.
(Methods) Because these complications seemed to be caused by diminished vascularity, we modified the technique to preserve the vascularity to the peripheral site of the neourethra. The modified OUPF IV (Koyanagi) was used to treat 6 patients with proximal hypospadias during the last 3 months.
(Results) Urethrocutaneous fistulas developed in 2 patients but meatal stenosis and meatal regression did not occur.
(Conclusion) We think this modification is suitable for severe proximal hypospadias.
