Experience with free grafts in urethral reconstruction.
A total of 33 patients underwent hypospadias or epispadias repair by patch or tubular grafts of skin or bladder epithelium from July 1980 to January 1985. Indications included previous circumcision, proximal primary hypospadias, severe chordee alone, inadequate local skin during extended urethroplasty at 2-stage hypospadias repair, multiple previous reconstructions and failed epispadias repair. Genital skin grafts were used in 25 patients, extragenital skin grafts in 4 and bladder epithelial grafts in 4. Complications occurred in 13 patients (39.4 per cent): 8 required reoperation for a fistula, stricture or diverticulum, and 5 underwent internal urethrotomy or urethral dilation. Of the 8 patients 3 needed more than 1 revision. These revisions were short and generally uncomplicated. Final results uniformly were good functionally and cosmetically. Based on our experience and that of others we believe that despite a high incidence of minor complications a free graft serves as an excellent substitute urethra for treatment of a variety of urethral problems in children.
