The urethroplasties were performed on 20 patients with hypospadias who had been admitted to the Department of Urology Chungnam National University Hospital from January, 1990 to March, 1993, After chordectomy the most common type of hypospadias
was
penoscrotal type(9 cases, 45%).
And the combined anomalies were 40% and the scrotal transposition was the most common. Of the 12 one-stage urethroplasties 7 were performed as Duckett method, 1 as MAGPI method, 2 as Hodgson I method, 1 as Hodgson II method and 1 as augmented
Duckett
method. Of the 8 two-stage urethroplasties 4 underwent as modified augmented Duckett method,. 1 as modified Duckett method with scrotal flap, 1 as Broadbent method, 1 as Rochet method and 1 as modified Rochet method with inguinal flap. The
complication
rate was 50%, in which the most common complication was urethrocutaneous fistula(7 cases, 35%). The complication rates by year were 71%, 50%, 43%, 0% from 1990 to 1993, respectively. This, it is though that the advance in operation technique may
be
very
important factor for successful operation. The methods of Duckett and augmented Duckett were used in minimal and moderate severe urethral defect and school age and modified two-staged Duckett method were performed in severe urethral defect and
preschool age without significant complications. So these results suggests that the methods using dorsal inner prepuce, which is adjacent to operation field, rich blood supply, good elasticity, no contracture after surgery, cosmetic advantage and
hairless, are recommended for choice of urethroplasty of hypospadias if possible.
