Comparison of Sensitivity & Specificity of Transvaginal Sonography, Saline Infusion Sonohysterography and Hysteroscopy in Evaluation of Women with Abnormal Uterine Bleeding

Introduction: Bleeding disorders are a common problem in daily practice, especially in premenopausal women. In our investigation, we compared the sensitivity and specificity of three different diagnostic methods; Trans-vaginal sonography(TVS), saline infusion sonohystrography(SIS) and Hysteroscopy. Methods: It was a cross- sectional study with a study population of ninety-nine women suffering fromAUB attending the outpatient clinic of Imam and Razi hospital in Ahvaz- Iran. They were evaluated by three different diagnostic methods and the results were compared. This study started from March 2008 to December 2008. The sensitivity, specificity, positive predictive and negative predictive values were measured in TVS, SIS, and finally these two methods were compared with hysteroscopy (as a gold standard). Results: The sensitivity and specificity of TVS was 74.2% and 49.7%, respectively, while that of SIS was 91.6% and 86%, respectively. The positive predictive value and negative predictive value of TVS was 7\.9% and 54.3%), respectively, while that of SIS was 85.9%) and 85.75%), respectively. The sensitivity, specificity, the positive predictive and negative predictive values of SIS was more than TVS, and it was similar to hysteroscopy. Conclusion: The findings obtained in the present study indicate that in AUB, sensitivity, specificity ^ positive and negative predictive value of SIS is more than TVS and therefore can be considered as a first step for diagnosis of AUB.
