Diagnostic accuracy of saline infusion sonohysterography for evaluation of uterine cavity abnormalities in patients with abnormal uterine bleeding

Objectives: The objective of this study was to evaluate the diagnostic accuracy of saline infusion hysterosonography for detection of uterine cavity abnormalities using Hysteroscopy as the gold standard. Study Design: Analytical Quasi Experimental study. Setting: Obstetric and Gynaecology Department Madina Teaching Hospital Faisalabad. Period: July 2017 to December 2017. Materials and Methods: Sixty patients presented with abnormal uterine bleeding were included in the study. Transvaginal ultrasound, SIS and hysteroscopy performed for evaluation of the uterine cavity for any abnormality. Results: SIS helped in detection of intacavitary abnormalities in 39 out of 60 patients indicating sensitivity of 88. 64 % and specificity of 100 % as hysteroscopy confirm the findings in all the patients. The NPV is 76 % and PPV of 100 % taking hysteroscopy as gold standard. The diagnostic accuracy of saline infusion sonography is 91%. Conclusion: The addition of SIS to TVS significantly improved the sensitivity and specificity for detecting intracavitary pathology. It can be used as an alternative procedure whenever hysteroscopy is not available.
