About this study
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.
Read the detailed description
The postmenopausal women with vaginal bleeding are selected in this cross-sectional study. The uterine bleeding in patients with blood system diseases, reproductive organ outside the uterus, other organs cancer metastasis to the uterus are excluded. The objects are divided into two groups(patients with endometrial benign diseases and patients with endometrial cancer and precancerous diseases) according to endometrial cytological and histological pathology. 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. Moreover,The specimen of uterine cytology and endometrial tissue are obtained through minimally invasive endometrium sampler, which were diagnosed by pathology.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 7 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Xiaofeng YANG, Doctor (0086-18602900810, yxf73@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The endometrial vascularization index (time frame: From March 2019 to December 2019). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2019; AzTrials last refreshed its copy on 8 Nov 2026.
