objective:To assess the utility of trans-vaginal ultrasonography in evaluation of non-pregnant sexually active female patients with lower ureteric calculi.Methods:A prospective study was done from January 2015 to December 2017 including non-pregnant sexually active females with suspected ureteric calculus.Trans-abdominal ultrasound was initially done in all patients.In those patients in whom trans-abdominal ultrasound was inconclusive or there was indirect evidence of lower ureteric calculus in form of ureteral dila-tion but no calculus was evident,trans-vaginal ultrasound was done.The patients with ureteric calculi detected on trans-vaginal ultrasound and kept on conservative management were also followed up with trans-vaginal ultrasound.Non-contrast computed tomography was done in patients with inconclusive trans-vaginal ultrasound.Results:As per the study protocol,156 out of the total 468 patients evaluated by trans-abdominal ultrasound were eligible for trans-vaginal ultrasound.Trans-vaginal ultrasound was done in 149 patients,as seven patients did not give consent.Seventy-nine patients were detected with a lower ureteric calculus on trans-vaginal ultrasound and 27 patients had gyne-cologic or other cause for their symptoms.Forty-three patients had an inconclusive trans-vaginal ultrasound of which 36 underwent non-contrast computed tomography,among them only one patient had a lower ureteric calculus.Stone free status could be easily demonstrated on follow-up trans-vaginal ultrasound.
