    Abstract:
    OBJECTIVE: The purpose of this study was to evaluate transvaginal ultrasonography (TVS) in differential diagnosis of vaginal bleedings in postmenopausal patients. MATERIAL AND METHODS: Between January 1990 and December 1996, 1198 postmenopausal patients with vaginal bleedings were sent to our clinic for a histological evaluation. Eight hundred and seventy-nine patients (73.4%) were preoperatively scanned by transvaginal probe, and endometrial thickness (< 5, 5-7, 8-10, > 10 mm) was measured. RESULTS: Atrophy was found in 46.3%, endometrial polyps in 19.8%, endometrial cancer in 17.5%, and hyperplasia in 6.7%. An endometrial thickness of lower than 5 mm (p < 0.0001) was shown in TVS patients with atrophy in 71%, with endometrial polyps in 10.9%, with endometrial cancer in 3.9% and hyperplasia in 6.8%. In 55.2% of these eases with endometrial cancer the preoperatively estimated thickness was 10 mm or more. The additionally morphologic examination in cases with an endometrium smaller than 5 mm was false positive in 75% (9/12). Thus an endometrial thickness of > 5 mm had a sensitivity of 92.5%, specificity of 71.0%, positive and negative predictive value of 75.6, respectively 90.9% for the detection of endometrial pathology. CONCLUSIONS: TVS allows the detection of an endometrial pathology in the vast majority of patients with postmenopausal bleedings. In cases with a single postmenopausal bleeding and an endometrium smaller than 5 mm we recommend expectative procedures with repeated ultrasound examination of the endometrium.
