Suboptimal results in full thickness skin graft urethroplasty using an extrapenile skin donor site.

We performed 22 full thickness skin graft urethroplasties for treatment of urethral stricture disease or hypospadias. Excellent results were achieved in 18 cases in which a penile skin donor site was used. Three failures occurred in 4 cases in which the full thickness graft was raised from the inner aspect of the upper arm. These results suggest caution when extrapenile skin is used for such repairs.
