title: Comparison of transvaginal ultrasonography and hysteroscopy in the diagnosis of uterine pathologies.
abstract: A thorough evaluation of the uterine cavity is frequently required in gynecology practice. The aim of this study was to compare the diagnostic values of transvaginal ultrasound examination and hysteroscopy in detecting uterine abnormalities in a group of patients within a range of menopausal status and symptomatology. This study included 285 patients admitted with complaints of abnormal uterine bleeding, postmenopausal bleeding, lower abdominal pain, abnormal vaginal discharge or for a routine gynecological examination. All patients had available transvaginal ultrasonography and hysteroscopy data for evaluation. A biopsy was obtained from all patients during the hysteroscopy session. Sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio were calculated for both methods and compared, considering the histopathological diagnosis as the gold standard. The mean age of the patients was 49.5±12.9 years (range, 24-89 y). Majority of the patients admitted for abnormal uterine bleeding (n=198, 69.4%). For the diagnosis of polyps of any size, hysteroscopy had better sensitivity (p<0.001), however, specificities did not differ (p=1.0). On the other hand, hysteroscopy did not have a sensitivity advantage over TVU in diagnosing polyps greater than 1 cm (p=0.077), although this time hysteroscopy had better specificity (p<0.001). Combined approach did not offer diagnostic advantage for any of the specific pathologies. Although TVU represents a practical approach for the initial evaluation of uterine pathologies, hysteroscopy seems to offer better diagnostic value for uterine pathologies in general, and uterine polyps in particular.
