Abstract

Background: Transvaginal ultrasonography (TVUS) is a non-invasive radiological investigation with more sensitivity and specificity to diagnose adnexal masses.

Aim: To determine the diagnostic accuracy of transvaginal ultrasonography (TVUS) for adnexal masses.

Study Design: Descriptive, cross-sectional.

Methodology: New but undiagnosed patients (n=100) who presented with obstetrical and gynaecological issues were enrolled at Sir Ganga Ram Hospital (SGRH), Lahore-Pakistan for 6 months. Every patient had trans-vaginal ultrasonography. The sensitivity and specificity of transvaginal ultrasound in diagnosing adnexal masses was calculated by using the OpenEpi Collection of Epidemiologic Calculators Version 3.01.

Results: The highest sensitivity and specificity was found for functional cysts USG (Sensitivity 92.9%, Specificity 98.8%) while the poorest USG correlation with pathology was of Malignancy (50%).

Conclusion: Transvaginal ultrasonography (TVUS) is a cheap diagnostic tool with high sensitivity and specificity for different adnexal masses.
