Diagnostic Accuracy of Transvaginal Sonography in Infertile Patients with Endometrial Polyps

Background: To evaluate the diagnostic accuracy of transvaginal sonography (TVS) in infertile patients and compare its results with hysteroscopy, as the gold standard. Materials and Methods: A total of 679 infertile women who underwent both TVS and diagnostic hysteroscopy were retrospectively investigated. TVS was performed in the mid-follicular phase (days 5-8) of their cycles. Sensitivity, specificity, and positive and negative predictive values were calculated for TVS. Results: Hysteroscopy diagnosed endometrial polyps in 197 out of 679 cases (24.5%). TVS confirmed the hysteroscopy findings in 174 of 197 (88.3%) cases. The sensitivity, specificity, and positive and negative predictive values of TVS compared to hysteroscopy in the detection of endometrial polyps were 88.3%, 91.9%, 81.6% and 90.8%, respectively. Conclusion: TVS is both a cost-effective and non-invasive method for the diagnosis of intra- uterine lesions such as polyps. When used in conjunction with a saline infusion, it can be a proper alternative for diagnostic hysteroscopy that saves time and enables the surgeon to perform the operative hystroscopy procedure with greater accuracy.
