Comparative Study
Transvaginal hysterosonography: comparison with biopsy in the evaluation of postmenopausal bleeding.
Transvaginal sonography is a highly sensitive method for detecting endometrial thickening. In the postmenopausal woman such thickening is non-specific and can be due to hyperplasia, polyps, submucosal endoluminal fibroids, or carcinoma. In such cases, transvaginal sonography combined with transvaginal hysterosonography may assist in the workup of these endometrial processes. ⋯ Of the five (11%) lesions that were malignant, three resulted in false-negative biopsies, one biopsy revealed hyperplasia, and only one biopsy was true positive. All 36 women with negative transvaginal hysterosonography examinations also had negative biopsy findings. We conclude that the combination of transvaginal sonography and transvaginal hysterosonography is more sensitive in the detection of endometrial pathologic lesions than is endometrial biopsy, and that transvaginal sonography or transvaginal hysterosonography should be included in the evaluation of women with postmenopausal bleeding.
