NCT07503938

Brief Summary

Endometriosis is traditionally considered a disease of reproductive-age women; however, residual lesions may persist after menopause and be detectable at imaging. The prevalence and sonographic characteristics of such findings in postmenopausal women remain poorly defined. This prospective observational study aims to assess the prevalence and ultrasonographic features of findings suggestive of deep endometriosis and endometrioma-like cysts in postmenopausal women undergoing routine gynecological examination using a standardized transvaginal ultrasound protocol. The study also explores clinical factors associated with these findings to improve interpretation and clinical management in this population.

Study Population

The study population consists of consecutive postmenopausal women aged 50 years or older attending gynecological outpatient clinics for routine clinical evaluation.

You may qualify if:

  • Women aged ≥50 years
  • Postmenopausal status, defined as ≥12 consecutive months of spontaneous amenorrhea not attributable to pregnancy, lactation, medical therapy, or other pathological causes
  • Attendance at participating gynecological outpatient clinics for routine examination
  • Ability to undergo transvaginal ultrasound examination

You may not qualify if:

  • Previous surgical and/or radiological diagnosis of endometriosis
  • History of hysterectomy and/or bilateral oophorectomy (any surgical approach)
  • Active pelvic malignancy at the time of enrollment
  • Inability to undergo or tolerate transvaginal ultrasound examination (e.g., severe introital stenosis, vaginismus, or never sexually active)
  • Non-interpretable ultrasound examination due to technical limitations
