Aim: Diagnostic accuracy of transvaginal ultrasonography in diagnosing endometrial hyperplasia in post-menopausal women with abnormal uterine bleeding taking histopathology as gold standard.

Settings & duration: Department of Radiology, CMH, Rawalpindi from 25-08-17 to 24-02-18

Methodology: A total of 203 post-menopausal females having AUB were included. Patients who had cervical and vaginal pathologies other than EH were excluded. The ultrasound was done with Endovaginal probe of Toshiba aplio 500. On ultrasound, endometrial thickness was taken. Endometrial biopsy was carried out using hysteroscopy. Final diagnosis was based upon histopathology report.

Results: In TVS positive patients, 103 were True Positive and 12 were False Positive. Among 88 TVS negative patients, 04 were False Negative whereas 84 were True Negative (p=0.01). Overall sensitivity, specificity, PPV, NPV and diagnostic accuracy of transvaginal ultrasonography in diagnosing endometrial hyperplasia in post-menopause women with abnormal uterine bleeding taking histopathology as gold standard was 96.3%, 87.5%, 89.6%, 95.5% and 92.1% respectively.

Conclusion: Diagnostic accuracy of TVS in diagnosing endometrial hyperplasia in post-menopause women with AUB is high, so TVS should be the first line investigation in diagnosis of endometrial hyperplasia.
