OBJECTIVE: We sought to evaluate risk factors for vesicovaginal fistula (VVF) after incidental cystotomy during benign hysterectomies.
STUDY DESIGN: All benign hysterectomies between January 2000 and May 2004 were reviewed. Demographic and operative data were abstracted. Cystotomies were graded using the American Association for the Surgery of Trauma (AAST) system. Patients developing VVF after cystotomy were compared to those who did not. Categorical variables were analyzed with Fisher exact test while Student t test was used for continuous data.
RESULTS: A total of 1317 benign hysterectomies were reviewed (46% abdominal, 48% vaginal, and 6% laparoscopically assisted vaginal). In all, 34 cystotomies occurred with 4 (11.7%) developing a VVF. Patients developing VVF were more likely to have an AAST grade V cystotomy (75% vs 7%; P = .004). Patients developing VVF trended toward greater tobacco use, larger uterine size, and more operative blood loss.
CONCLUSION: Patients with an AAST grade V cystotomy are at increased risk for VVF formation.
