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.
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.
TVS is both a cost-effective and non-invasive method for the diagnosis of intrauterine 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.
