One-stage penile/preputial cutaneous island flap urethroplasty for urethral stricture: a preliminary report.

A 1-stage urethroplasty for urethral strictures is described using a transverse distal penile or preputial island of skin as a flap, which is supplied axially by the superficial external pudendal vessels. This portion of the skin is hairless and the pedicle is constructed so that the skin can reach anywhere from the external meatus to the prostatic urethra for reconstruction as a patch or tube. In 10 cases reviewed urethroscopically for intervals of 5 weeks to 6 months there was 100 per cent graft take with no stenosis at the anastomotic sites and no permanent fistula. There was 1 residual stricture owing to incomplete excision of the original stricture and 3 fine hairs were seen in 2 new urethras. Mucous membrane or mucocutaneous bridges occurred in 4 patients owing which were divided easily.
