Abstract

Objective

To evaluate the accuracy of transvaginal sonography (TVS) and saline infusion sonohysterography (SIS) for detection of uterine cavity abnormalities in patients with abnormal uterine bleeding (AUB) taking hysteroscopy as the gold standard.

Methods

This was a prospective study done in the department of Obstetrics and Gynecology of a tertiary care academic hospital. Sixty premenopausal and postmenopausal women who presented with AUB underwent TVS, SIS, and hysteroscopy. The presence of focal abnormality and the type of abnormality, i.e., polyp, submucous myoma, and endometrial hyperplasia, were noted. The results of TVS and SIS were compared with hysteroscopy.

Results

On hysteroscopy, 76.67 % (n = 46) patients were diagnosed with intra cavity abnormalities. SIS showed sensitivity, specificity, PPV, and NPV of 89.1, 100, 100, and 73.7 %, respectively. In comparison, TVS showed sensitivity, specificity, PPV, and NPV of 43.48, 78.57, 86.96, and 29.73 %, respectively.

Conclusions

SIS was found to be more sensitive and specific than TVS in detection of intra cavity abnormalities.
