Diagnostic Accuracy of Trans Vaginal Sonography in Detecting Vesicovaginal Fistula

Abstract

Objective: The aim to conduct this study was to establish the diagnostic accuracy of trans vaginal sonography to detect vesicovaginal fistula. Findings are compared with cystogram and surgical results, taking later as gold standard. Settings: The study was conducted in the Department of Radiology, FJMU/Sir Ganga Ram Hospital, Lahore Pakistan. Duration: September 2022 to March 2023. Methods: All patients who were included in study, were married females within age bracket of 32-42 years, who presented in outpatient department with the complaint of urinary incontinence. Trans vaginal ultrasound was performed after verbal consent. Findings were compared with cystogram and surgical results, taking later as gold standard. Patients who suffered stress incontinence during physical movement or activity were excluded from this study. Results: A total of 25 patients were taken. The age range was 32-42years with mean age of 36years. The fistulae were seen by transvaginal ultrasound in all cases with the site, size and number of communicating tracts corresponding with operative results. Trans vaginal sonography reveals 100% sensitivity to detect vesicovaginal fistulae. Conclusion: We recommend transvaginal ultrasound as an accurate imaging modality for detecting vesicovaginal fistula because its findings are correlated well with the surgical results and is non-invasive, safe, non-hazardous and without any risk of radiation exposure.
