Laser welding of vesicovaginal fistula.

The management of vesicovaginal fistula remains a source of debate, despite extensive literature on the subject. It is difficult to prove the superiority of one surgical technique over another by randomized trials, given the variabilities of fistula etiology, the location and clinician expertise. Small epithelized fistulae following conservative treatment and residual or recurrent cases following transabdominal or transvaginal repair pose a therapeutic challenge. A case of a small vesicovaginal fistula following abdominal hysterectomy is presented, in which a successful outcome was achieved using endoscopic Nd-YAG laser fulguration.
