Transvaginal ultrasound, uterine biopsy and hysteroscopy for postmenopausal bleeding

Abstract

When the thickness of the endometrial echo is less than 3 mm there is no need for anatomopathologic investigation. When this limit was adopted, all cases were associated with endometrial atrophy, and when the limit was 4 mm or more, active endometria were detected, requiring further histopathologic investigation by hysteroscopy and directed biopsies. Above 8 mm, malignancy may be found.
