Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Introduction: Evaluation of abnormal uterine bleeding (AUB) in women ≥ 40 years or menopausal women is of critical importance to confirm the benign nature of the problem, and to exclude endometrial carcinoma.This study was designed to evaluate the accuracy of saline infusion sonography (SIS) compared to hysteroscopy in diagnosing uterine cavity abnormalities in cases of AUB.Material and methods: One hundred and eighty-six women diagnosed with AUB were included in this comparative study, and agreed to have SIS, beside the hysteroscopic assessment of the uterine cavity.Results: In this study, hysteroscopy was more sensitive (98.7% vs. 97.4%),more specific (100% vs. 99.1%),and more accurate (99.5% vs. 98.4%) than SIS.In addition, hysteroscopy had higher predictive values, 100% positive predictive value, and 99.1% negative predictive value compared to 98.7% positive predictive value, and 98.2% negative predictive value for SIS in diagnosis of uterine cavity abnormalities.However, these differences were not statistically significant (p > 0.05).Conclusions: Saline infusion sonography is a simple, well-tolerated procedure that can be used in an outpatient setting to diagnose uterine cavity anomalies in cases of abnormal uterine bleeding when outpatient hysteroscopy is not available or as a complementary tool to confirm the diagnosis detected by hysteroscopy.
