Abstract
Surgical repair of urethral strictures complicated by multiple scrotal/perineal urethrocutaneous fistulae (watering-can perineum) can be very problematic. The perineal/scrotal skin is either not available or is riddled with infection, fibrosis or granulomata and therefore unsuitable as a graft source. The presence of infection makes free grafts from other sites unlikely to survive. Furthermore, extensive fibrosis may prevent excision and re-anastomosis as well as internal urethrotomy. The absence of preputial skin in circumcised patients compounds these problems. We have used a one-stage, transverse vascularized cutaneous penile flap to repair 20 cases of these complicated strictures. The graft took in 100% and no absolute repair failure was registered. In spite of obvious pre-operative infection, the result of repair was judged excellent in 17 patients (85%) and very fair in 3 (15%).
