摘　　要：Objective:The surgical repair of hypospadias is done in two stages in a select group of patients with severe anomaly.The first stage(Ⅰ)procedure consists of correction of penile shaft curvature and second stage(Ⅱ)repair involves the creation of a neourethra.This neourethra needs a cover of an intermediate layer in order to have good functional and cosmetic results.Among the various local flaps,tunica vaginalis flap is a good option for the use as an intermediate layer.Methods:We have managed 22 patients of chordee with hypospadias by staged repair.In Stage I,chordee correction was done by dividing the urethral plate and covering the penile shaft with dorsal prepucial flaps.In Stage Ⅱ,a neourethra was created and covered with tunica vaginalis flap either through the same incision(14/22)or via a subcutaneous tunnel(8/22).An indwelling catheter was kept for 10 to 12 days.Results:Eighteen(81.8%)patients had successful functional and cosmetic repair.Two patients(9.1%)had urethrocutaneous fistula of which one healed on subsequent dilatation while the other one(4.5%)needed repair.Overall fistula formation rate was 4.5%.In two patients,the external urinary meatus could be made upto subglanular or coronal level.Conclusion:Staged repair of chordee with hypospadias is valuable in selected group of patients and tunica vaginalis flap is an excellent intermediate layer to cover the neourethra.However preoperative counseling is particularly essential in patients where the external urinary meatus can be created at coronal or subglanular level.
