The use of pedicled omentum in the repair of large vesicovaginal fistulas. Experimental work in dogs.

Large vesicovaginal fistulas involving most of the trigone were created in eight dogs. Three weeks postoperatively, pedicled omentum was insinuated between the open bladder and vaginal defects. Bladder continuity was present at 2 weeks and epithelization was complete at 3 weeks postoperatively. There was little morbidity and no mortality.
