Prevalence of Amsel-defined Bacterial Vaginosis Before and After Transvaginal Ultrasound with Lubricant Application

Emerging evidence suggests a link between hyperosmolal vaginal lubricants and bacterial vaginosis (BV). In 80 patients undergoing transvaginal ultrasound (TVUS) with a standardized lubricant, we observed a significant increase in Amsel-defined BV 1-13 days post-TVUS compared to baseline, likely driven by heightened amine odor (OR: 5.88; 95% CI: 1.22-28.23).
