Free or pedunculated skin flaps may be used to repair stenoses of the anterior urethra. The authors prefer using free preputial flaps in reconstructing the bulbar urethra which, having a spongy body, guarantees an adequate vascular and mechanical support for the transplanted flaps. The bulbar reconstruction technique uses an epidermal epithelial strip along the dorsal face of the urethra. The dorsal approach to the urethral channel prevents mechanical yielding of the transplanted area and consequent formation of symptomatic urethrocele. Dorsal enlargement urethroplasty has the advantage that invasion of both the area of skin removal and the urethral channel is reduced to a minimum.
