Endometrial Thickening

For pre-menopausal patients with abnormal uterine bleeding (AUB), pick correct category below.

  •  Normal thickness <16mm
  •  Abnormal thickness = or >16mm
  •  Focal lesion (focal thickening or polypoid lesion suspected)

For post-menopausal patients with abnormal uterine bleeding (AUB).

  •  Normal thickness <5mm
  •  Abnormal thickness = or >5mm
  •  Focal lesion (focal thickening or polypoid lesion suspected)

For post-menopausal patients who are asymptomatic (no bleeding), need to know whether patient is on HRT or Tamoxifen from Pelvic US worksheet.

  •  If NOT on HRT or tamoxifen, abnormal is >6mm
  •  If on HRT, abnormal is >8mm
  •  If on Tamoxifen, abnormal is >8mm
