Role of sonohysterography in evaluation of abnormally thickened endometrium causing abnormal uterine bleeding with...

This prospective randomized study was carried out in the department of Radiology and Imaging in collaboration with the department of Obstetrics and Gynecology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag and Dhaka Medical College Hospital (DMCH) during the period of January 2003 to December 2004. The aim of this study was to establish sonohyterography as a sensitive tool and superior to Transvaginal Sonography (TVS) for detection of endometrial pathology in women with abnormal uterine bleeding (AUB) and its validity by determining sensitivity, specificity, accuracy, positive predictive value and negative predictive value. For this purpose, a total number of 40 patients who had thickened endometrium (cut off level < 15 mm for pre menopausal and < 5 mm for post menopausal patients) detected on transabdominal or transvaginal sonography were selected. TVS and TV-SH were done in all these patients and findings were then compared with the final histopathological diagnosis. In our study, we found TV-SH has sensitivity of 100%, specificity of 80% and accuracy of 97.5% compared to TVS (94%, 66.66% and 90% respectively) in detection of endometrial pathology in women with AUB. TV-SH can thus be regarded as one of the most sensitive, specific and accurate modality in detecting and excluding endoluminal masses as the cause of AUB. It can be considered as the initial examination in the evaluation of all women with AUB.
