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.
