Diagnostic Value of Saline Contrast Sonohysterography Comparing With Hysteroscopy For Detecting Endometrial Abnormalities in Women With Abnormal Uterine Bleeding

Background: abnormal uterine bleeding is a common presentation of uterine abnormalities among premenopausal and postmenopausal women. objective: to evaluate and compare the diagnostic accuracy of saline contrast sonohysterography and hysteroscopy for detecting the cause of abnormal uterine bleeding. materials and methods: a total of 65 women with abnormal uterine bleeding were enrolled in this study. a prior saline contrast sonohysetrography followed by a hysteroscopy was performed in all cases. sensitivity, specificity, positive and negative predictive value and test accuracy were calculated. results: as the most common abnormality, scsh showed hyperplasia in 19 patients while hysteroscopy diagnosed polyp in 15 cases. a sensitivity of 73.3%, 71.4% and 90.9% were reported for polyp, hyperplasia and submucous myoma respectively whereas the specificity was calculated 96% for polyps, 82.3% for hyperplasia and 90.7% for submucous myoma. conclusion: comparing with hysteroscopy, sonohysterography showed a high sensitivity and specificity for detecting submucous myoma but not for endometrial polyp and endometrial hyperplasia
