[Severe hypospadias repair: reconstructing penis, scrotum and urethra].

OBJECTIVE: To investigate the surgical technic of re-shape penis and scrotum, as well as construct urethra in severe hypospadias patients. METHODS: Twenty-two cases of perineal hypospadias with abnormal penis and scrotum were involved in operative repair. All the patients underwent two-stage of repair technic. The penis sponge were completely stretched out and uprighted in the first-stage. Foreskin and partial penis back skin was transferred into the ventral of penis and scrotum crack. At second-stage, urethroplasty was performed using bladder mucosa folded into half tube that sutured with urothra plate to reconstruct the urothra. The scrotum were re-shaped using foreskin and skinflap. RESULTS: The operation's successful rate was 68% (15/22). There were 7 cases (32%) suffered from urethrocutaneous fistula and recovered after repair. Five cases (23%) occurred stricture of urethra and were treated by urethra dilatation. The appearance of penis and scrotum in 22 cases were satisfied. CONCLUSIONS: The operative methods should be made according to the type of hypospadias and of scrotum. The technic were effective on severe hypospadias with abnormal scrotum, even for the patients who need more than 10 cm urethra construct. The appearance of penis and scrotum were satisfied after following up.
