Vaginal ultrasonography in patients with postmenopausal bleeding

Authors


Abstract

Our objective was to define a subset of women with postmenopausal bleeding in whom the accepted practice of endometrial sampling could be safely omitted. Vaginal endosonographic measurements were compared to the histological findings of curettings following diagnostic dilatation and curettage in 129 women with post-menopausal bleeding who were not receiving hormonal therapy. Atrophy was diagnosed in 49%, slight proliferation in 10%, endometrial polyps in 11%, hypoplasia in 12%, and adenocarcinoma in 12%. Endometrial atrophy was associated with a mean sonographic thickness of 2.6 mm of the double layer (range 0–6.5 mm). Of the women with a final histological diagnosis of atrophy, 92% had an endometrial thickness of 3 mm or less. Furthermore, all women with a sonographic endometrial thickness of 3 mm or less had atrophic endometrium (p < 0.0001). An endometrial thickness of 3 mm or less would have reduced the number of dilation and curettage procedures by 45% and no cases of endometrial pathologies would have been missed. In women presenting with postmenstrual bleeding, meticulous scanning of the endometrium can select a group where endometrial sampling can be omitted from the protocol.
