[Reconstruction of urethra partial defect with scrotal flap].

OBJECTIVE

To introduce the application of the scrotal flap on reconstructing partial urethra defect.

METHODS

From March 1998 to August 2004, 31 patients with urethra defect were treated with scrotal flap. Their ages ranged from 6 to 34 years. Thirty-one patients included 8 cases of congenital deformity of urethra and 23 cases of complication of urethral fistula, urethral stenosis and phallus bend after hypospadias repair. The flap widths were 1.5-2.5 cm in child and 2.5-3.5 cm in adult. The flap length was 1.5-2.0 times as much as the width. Nine cases were classified as penile type, 10 cases as penoscrotal type, 7 cases as scrotal type (3 children in association with cleft scrotum) and 5 cases as perineal type because of pseudohermaphroditism. Urethroplasty was given by scrotal fascia vascular net flap to reconstruct urethra defect.

RESULTS

All the flaps survived, and the incision healed well. Twenty-four cases achieved healing by first intention and 7 cases by second intention. And fistula occurred and healed after 2 weeks in 1 case. 27 cases were followed up 1-4 years, 2 cases had slight chordee, the others were satisfactivly.

CONCLUSION

Urethroplasty with scrotal fascia vascular net flap is an ideal method for the partial defect urethra.
