Microsurgicai techniques in one-stage urethroplasty for hypospadias

Objective To evaluate the efficacy of one stage urethroplasty with microsurgical technique and a pedicle skin tube in the treatment for hypospadias.Methods One stage urethroplasty using microsurgical technique and pedicle skin tube was carried out in 87 cases of hypospadias. The age ranged from 9months to 14yrs(mean 4yrs). There were penile type in 36 cases, penoscrotal type in 39 and perineal type in 12.Results The successful rate was 91.7% (34/39) in penile type, 87.2% (34/39) in penoscrotal type and 66.7% (8/12) in perineal type respectively. The successful rate was 100% for patients under 16 months of age, 85.7% for cases under 3 years of age, 83.3% for those old than 3 years.Conclusions One stage urethroplasty using microsurgical technique and a pedicle skin tube is an effective method for hypospadias. It should be operated on an earlier age so as to achieve better results in children.
