Summary

Transvaginal ultrasonography accurately assesses endometrial thickness in postmenopausal women with metrorrhagia. An endometrial depth of 10 mm or less significantly minimizes the risk of endometrial cancer.

Area of Science:

  • Reproductive Endocrinology
  • Diagnostic Imaging
  • Gynecologic Oncology

Background:

  • Metrorrhagia is a common symptom in postmenopausal women, necessitating accurate diagnostic tools.
  • Endometrial cancer risk stratification is crucial for appropriate patient management.
  • Transvaginal ultrasonography (TVS) is a non-invasive imaging modality for evaluating the female reproductive system.

Purpose of the Study:

  • To evaluate the utility of transvaginal ultrasonography in measuring endometrial thickness.
  • To determine the association between endometrial thickness and the risk of endometrial cancer in postmenopausal women with metrorrhagia.
  • To assess the diagnostic performance of TVS in identifying endometrial cancer.

Main Methods:

  • A study cohort of thirty-one postmenopausal patients was analyzed.

Related Experiment Videos

  • Twenty-three patients presented with metrorrhagia.
  • Transvaginal ultrasonography was employed to measure endometrial depth.

    • Main Results:

    • An endometrial depth of less than or equal to 10 mm was associated with minimal risk of endometrial cancer.
    • TVS demonstrated a sensitivity of 75% and a specificity of 89% for detecting endometrial cancer.
    • The positive predictive value was 60%, and the negative predictive value was 94%.

    Conclusions:

    • Transvaginal ultrasonography is a valuable tool for assessing endometrial thickness in postmenopausal women with metrorrhagia.
    • An endometrial thickness threshold of 10 mm effectively differentiates low-risk from potentially higher-risk cases.
    • TVS exhibits good diagnostic performance for endometrial cancer, particularly in ruling out the disease (high negative predictive value).
