Introduction and hypothesis
To evaluate factors for vesicovaginal fistula (VVF) formation following incidental cystotomies during benign hysterectomies.
Methods
Hysterectomies performed at two university centers between January 1, 2000 and December 31, 2008 were reviewed. Demographic and operative data were abstracted. Patients who developed VVF were compared to those with no VVF.
Results
During the study period, 5,698 hysterectomies performed for benign indications were identified. One hundred two (1.8%) cystotomies occurred with 6 (5.9%) developing a VVF. Patients with VVF were more likely to have uteri weighing >250 g (83% vs. 36%, P = 0.03), had longer surgeries (317 ± 82 vs. 208 ± 10 min, P = 0.02) and more ureteral injuries (33% vs. 1%, P = 0.009). American Association for the Surgery of Trauma (AAST) grade V bladder injuries (OR, 93.00; 95% CI, 10.30–838.92) were associated with VVF formation.
Conclusions
Patients with AAST grade V bladder injuries are at increased risk for developing vesicovaginal fistulas following incidental cystotomies during benign hysterectomies.
