[Evaluation of ultrasonographic variables of the endometrium in relation with histopathologic findings in patients with postmenopausal uterine bleeding].

The purpose of this study was to determine the sensitivity, specificity, positive and negative predictive value of analyzed variables in the ultrasonographic endometrial study in patients with postmenopausal uterine bleeding. Nineteen women with postmenopausal uterine bleeding were studied, in all of them and in the same day a transvaginal ultrasound and endometrial biopsy were performed. It was observed that endometrial thickness median was 4 mm; most of the endometria were proliferative (n = 12), and a greater trend to obesity and upper segment fat distribution was found. Endometrial thickness, refringence and liquid on uterine cavity had a sensitivity and a negative predictive value NPV) of 100%, specificity and positive predictive value were lower. When endometrial thickness and refringence were associated also a sensitivity and NPV of a 100% was found. It can be concluded that transvaginal ultrasound is useful to define in which patient with postmenopausal uterine bleeding the endometrial biopsy is indicated.
