RESUMEN
Twety seven children with penile hypospadias were treated using urethroplasty with transverse cutting island prepuce flap with local vascular pedicle from the dorsal penile rampant skin,and stabed hole at nonvascular region in middle of pedicle,reversed tubed flap through the penis to the ventral,anastomosed with the primary distal urethral.All cases were repaired successfully one stage,two cases with urethral fistula and one case with extemal orifice stricture of urethra.The appearance of the penis were satisfactory.It is suggested that one stage repair of penile hypospadias with urethroplasty improved transverse cutting island prepuce flap(Duckett's technique),the area of tubed flap sutured cling venial tunica albuginea penis,and bilateral is covered with vascular pedicle,greatly reduces the occurrence of urethral fistula.
