All patients underwent hysteroscopy after a previous transvaginal ultrasound to compare the results. The hysteroscopy was performed by experienced examiners, and transvaginal ultrasounds were performed in various public and private services, which is reflective of routine healthcare practices in obstetrics and gynecology. The sensitivity, specificity, and accuracy of the transvaginal ultrasound were calculated using hysteroscopy as the gold standard. The level of agreement between the two exams was calculated using the Kappa test.<\/jats:p><jats:p>\n          Results\u2003The mean age was 56.55\u2009\u00b1\u200912.3 years. For endometrial polyps, we observed a sensitivity of 39.8%, specificity of 72.7%, accuracy of 52.8%, and Kappa index of 0.11 (p\u2009=\u20090.025). For fibroids, the sensitivity was 46.7%, specificity was 95.0%, accuracy was 87.9%, and Kappa index was 0.46 (p\u2009&lt;\u20090.001). For endometrial thickening, the sensitivity was 68.7%, specificity was 41.7%, accuracy was 47.6%, and Kappa index was 0.06 (p\u2009=\u20090.126). For endometrial atrophy, we found a sensitivity of 6.7%, specificity of 99.3%, accuracy of 90.2%, and Kappa index of 0.10 (p\u2009=\u20090.006). For the other findings, the sensitivity was 15.6%, specificity was 99.6%, accuracy was 87.3%, and Kappa index was 0.23 (P\u2009&lt;\u20090.001).<\/jats:p><jats:p>\n          Conclusion\u2003Our study demonstrated a low level of accuracy of transvaginal ultrasound for the diagnosis of endometrial lesions, when performed by a non-experienced professional. Thus, it is important to consider the use of hysteroscopy to avoid unnecessary and inappropriate treatments.<\/jats:p>","DOI":"10.1055\/s-0041-1732462","type":"journal-article","created":{"date-parts":[[2021,8,30]],"date-time":"2021-08-30T22:33:03Z","timestamp":1630362783000},"page":"530-534","source":"Crossref","is-referenced-by-count":10,"title":["Accuracy
