Pregnancy Of Unknown Location

Abstract Background: Pregnancy of unknown location (PUL) is a kind of pregnancy that has a positive beta-human chorionic gonadotropin (β-hCG) test result but the location of pregnancy cannot be determined by ultrasound. Early determination of the location of the pregnancy is important for subsequent treatment. However, there is no study on the characteristics of vaginal microbiota in pregnant women with unknown locations and a model for judging it by vaginal microbiota combined with clinical indicators. Therefore, we designed this study to compare the characteristics of vaginal microbiota in intrauterine and ectopic pregnancy populations during pregnancy with unknown locations and to establish a prediction model for pregnancy locations in PUL populations with clinical indicators.Methods: This is a prospective, multicenter cohort study. 576 eligible participants will be included in this study. Vaginal microbiota was collected from all participants at inclusion, and color Doppler ultrasound was performed weekly. After the locations of pregnancy were determined, participants of intrauterine pregnancy were followed up to their early pregnancy outcome, and participants of ectopic pregnancy were followed up until a none-pregnancy level of β-hCG was confirmed. Discussion: The regular method of judging the location of pregnancy is by color Doppler ultrasound and β-hCG test. We hope to provide earlier clinical methods of prediction for women with unknown locations of pregnancy through this study.Trial registration: Chinese Clinical Trial Registry: ChiCTR2000035378, registration date: 9 August 2020. http://www.chictr.org.cn/index.aspx

In recent years, with the development of color Doppler ultrasound technology in obstetrics, this noninvasive, direct, convenient, and sensitive inspection method has become one of the best methods to observe the fetal circulation in the uterus. This paper discusses the clinical value of using transvaginal color Doppler ultrasound in the differential diagnosis of ovarian corpus luteum disease and ectopic pregnancy disease. This paper selects 100 cases of ectopic pregnancy and 100 cases of pregnant corpus luteum as the experimental research objects. Clinical analysis of transvaginal color Doppler ultrasonography was performed on all patients. In the process of measuring the patient’s ectopic pregnancy, the size of the patient’s adnexal mass is mainly measured, and the blood flow spectrum is measured. The clinical choice of transvaginal color Doppler ultrasound method to distinguish ectopic pregnancy disease and corpus luteum pregnancy disease can play a significant value. It can be effectively diagnosed according to the type of disease, then effective methods can be studied for clinical treatment, the quality of life of patients with the two diseases can be significantly improved, and the clinical application value of color Doppler ultrasound can be improved.
