This technique is helpful for selecting patients for diagnostic tests. This study was designed to determine the validity of transvaginal sonography in the measurement of endometrial thickness.<br> <strong><em>Materials and Methods:</em></strong> A total of 71 women who were admitted for abdominal hysterectomy due to different causes in Kosar Hospital (2008&ndash;2009) were enrolled in the study. The main exclusion criteria was inability to measure endometrial thickness via transvaginal sonography. Endometrial thickness measurements were done prior to surgery. Histopathologic measurement of the fresh specimen was carried out immediately after surgery. Data were analyzed using T-test and kappa index.<br> <strong><em>Results:</em></strong> No ultrasound measurement was possible in 15% (11) of the patients. No statistically significant difference was observed in endometrial thickness between the two procedures. Taking into account 5 mm as a cut&ndash; off point, in 70% (42) of the patients, endometrial thickness was<span dir="RTL"> > </span>5 mm in both procedures. In 30% (18) of the patients, endometrial thickness in sonography was >5 mm, 11 cases of which were confirmed by histopathologic measurement. The remaining 7 cases were falsely reported as thick endometrium by sonography. The overall accuracy of sonography was about 83/3%, which was more efficient for samples with thin endometrium (89/8% vs. 72/8%).<br> <strong><em>Conclusion:</em></strong> Despite a concordance between transvaginal sonography and histopathology results for endometrial thickness evaluation, the former is faced with limitation as a single diagnostic test.</p> Keywords: Endometrial thickness, Transvaginal ultrasound, Abnormal uterine bleeding 107 114 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-610&slc_lang=fa&sid=1 Farideh Movahed فریده موحد fmovahed@qums.ac.ir 5200319475328460060059 5200319475328460060059 Yes Faculty of Medicine, Qazvin University of Medical Sciences, Qazvin, Iran. متخصص زنان، استادیار دانشگاه علوم پزشکی و خدمات بهداشتی درمانی قزوین Amir Javadi امیر جوادی 5200319475328460060060 5200319475328460060060 No Dept. of Social Sciences, Medical Faculty.
