NCT03289468

Brief Summary

The postmenopausal women with vaginal bleeding were selected in this cross-sectional study. The basic characteristics information and endometrial blood flow energy index of endometrium were detected by color power Doppler ultrasound, and the energy histogram of endometrium was obtained. The specimen of uterine cytology and endometrial tissue were obtained through minimally invasive endometrium sampler, which were diagnosed by pathology. The statistical data were used to detect endometrial and precancerous lesions to observe the endpoint, and to provide the energy histogram model of the early warning endothelial diseases.

    From March 2019 to December 2019

Secondary Outcomes (3)

  • The ultrasonography of endometrium

    From March 2019 to December 2019

  • The endometrial thickness

    From March 2019 to December 2019

  • The blood flow index of endometrium

    From March 2019 to December 2019

Study Arms (2)

Group1

Endometrial Benign Disease

Diagnostic Test: Voluson E8 (GE Medical Systems, USA), Minimally Invasive Endometrium Sampler

Group2

Endometrial Cancer and Precancerous Lesions

Diagnostic Test: Voluson E8 (GE Medical Systems, USA), Minimally Invasive Endometrium Sampler

Interventions

The endometrial thickness, basic characteristics information and endometrial blood flow energy index, endometrial vascularization index, blood flow index are detected by color power Doppler and the energy histogram of endometrium is obtained using a Voluson E8 (GE Medical Systems, USA) ultrasound system. The specimen of uterine cytology and endometrial tissue are obtained through minimally invasive endometrium sampler, which are diagnosed by pathology.
