The goal of this observational study is to evaluate the feasibility, safety, and effectiveness of a fully enclosed protective device system in laparoscopic myomectomy to achieve tumor-free protection throughout the entire surgical procedure in women aged 28-46 years diagnosed with uterine fibroids who require laparoscopic myomectomy. The main questions it aims to answer are: Can the fully enclosed protective device system successfully achieve complete physical isolation of fibroid tissue during laparoscopic myomectomy and morcellation? Does the use of this device reduce the risk of tissue dissemination or leakage while maintaining acceptable surgical outcomes such as operative time, blood loss, and postoperative recovery? Participants will undergo laparoscopic myomectomy assisted by the fully enclosed protective device system. During the procedure, participants will: undergo laparoscopic removal of uterine fibroids using a fully enclosed protective isolation system have the fibroid dissected and contained within a protective bag during the entire procedure receive in-bag morcellation or fragmentation of fibroid tissue within a sealed environment be evaluated for operative outcomes including fibroid size, operative time, intraoperative blood loss, integrity of the protective bag, and postoperative hospital stay

In our previous study, based on the multi-center clinical big data collected from January 2012 to January 2025, we have completed the construction of a multimodal early warning model for the malignant transformation of uterine fibroids. The model was mainly based on T2WI and DWI sequences, and was trained and optimized by support vector machine (SVM) algorithm. In the retrospective study and internal validation, the model shows high sensitivity and specificity, which preliminarily proves that it has good application potential in identifying high-risk groups and predicting the risk of malignant transformation of uterine fibroids. However, there are still some limitations in retrospective studies and internal validation results, and its application value, universality and stability in real clinical environment have not been fully verified. Therefore, we plan to conduct a prospective validation study in consecutive patients enrolled after January 2025 to evaluate the clinical performance and generalization of the model in predicting the malignant tendency or risk of malignant transformation of uterine fibroids through practical application in the real population, and further analyze the operability in the actual diagnosis and treatment process and the potential value for patient management. This study will provide reliable evidence for early screening, follow-up management and individualized treatment of high-risk population, and has important clinical and public health significance for improving the early diagnosis rate, reducing the risk of malignant transformation and improving the prognosis of patients with uterine fibroids.
NCT07173127
Uterine fibroids and endometriosis are two frequent diseases among women of reproductive age. They can be responsible for chronic and/or menstrual pelvic pain and abnormal uterine bleeding. The first-line management of these conditions relies on medical treatment. Hormonal treatment with contraceptive pill can be effective, although up to 30% of patients do not respond to this line of treatment. In this context, GnRH antagonists have been introduced. By suppressing ovulation, they inhibit the action of the gonadal axis and thus can reduce bleeding and pain associated with uterine fibroids and endometriosis. More recently, the GnRH antagonist known as Relugolix has been associated with a low-dose oestradiol and progesteron-line molecule, a medication known as Ryeqo. The goal of this type of treatment is to suppress ovulation while also minimizing symptôms which may derive from lack of oestrogen and progesterone in reproductive age women. While Ryeqo's efficacy has been proven by multiple large randomized controlled trials, its impact on blood coagulation has yet to be determined. Venous thromboembolism (VTE) is the main, potentially fatal, dleterious effect of oestrogen-containing hormonal treatmen, such as combined oral contraceptives (COC). Several epidemiological studies have found a 3-6 increase in the risk of VTE among women on COC. The thrombogenic risk can be assessed by measuring specific blood biomarkers, which are known to be correlated to the thrombogenic phenotype and allow an overview of the VTE risk prior to conducting large population-scale studies directly measuring the adverse event's prevalence. The aim of this study is to document the effects of Ryeqo® on hemostasis parameters in order to estimate the risk of VTE associated with its employ. An improved understanding of the VTE risk associated with Ryeqo® will allow to adapt hormonal treatment based on each woman's personal risk profile. The study will be explained to all women whose medical condition allows the prescription of Ryeqo. All women who give their consent to participate in the study will have a urinary pregnancy test and a blood sample drawn before beginning treatment with Ryeqo. A second visit will be scheduled at 3 months, throughout which a second blood sample will be drawn. A questionnaire including socio-demographic data and clinical symptoms will be completed both on the first and the second visit.
NCT07137299
The goal of this observational study is to evaluate the impact of different hysterectomy (removal of the uterus) techniques on the risk of pelvic organ prolapse (situation when one or more of your pelvic organs like your bladder, uterus, or rectum have dropped down or slipped out of their normal position, sometimes even bulging into the vagina) and urinary incontinence (leaking urine unexpectedly) in women aged 18-85 who underwent hysterectomy or supracervical hysterectomy (removing of the uterus without its cervix) for benign (not cancer) conditions. The main question is: to check how different surgical technique (laparoscopic, with opening the abdomen, vaginal and robotic) increase the risk of pelvic organ prolapse or urinary incontinence There is no randomization or control group; comparisons will be made between surgery types based on clinical and questionnaire data. Participants will: * Receive an invitation to participate if they underwent hysterectomy between 2021-2025. * Fill out validated quality of life questionnaires (P-QOL, POPDI-6, PFIQ-7) every two years. * Attend follow-up clinical pelvic exams every two years to assess vaginal cuff healing, pelvic organ prolapses (POP-Q system), and urinary symptoms. This prospective, non-commercial, multicenter study plans to enroll 2,000 women and will run from July 1, 2025, to July 1, 2036

NCT02831556
Summary 1. Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. 2. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.

NCT05840042
Uterine fibroids are the most common form of benign uterine tumors in the uterine muscle layer, which had a certain rate of malignancy, but it is rare. The prevalence of uterine fibroids estimates range from 4.5% to 68.6% depending on study population and diagnostic methodology. The prevalence of fibroids has been historically underestimated by epidemiologic studies which focused mainly on symptomatic women, leaving behind a large population of asymptomatic women and women who underreport their symptoms. What investigators don't know was which women who have fibroids will develop clinical symptoms and which women who have an operation of myomectomy will relapse. The purpose of this study is to investigate the prevalence, incidence and risk factors for the development of uterine fibroids in Chinese women.

NCT03317795
This is a randomized controlled trial (RCT) to assess the comparative effectiveness of Levonorgestrel Intrauterine System (LNG-IUS) to Tranexamic Acid (TA) for the treatment of heavy menstrual bleeding (HMB) in women with clinically-significant fibroids.
NCT03444987
Uterine fibroids (UFs), also called uterine leiomyomas or myomas, are steroid hormone-responsive, benign tumors of the smooth muscle compartment (myometrium) of the uterus. They are the most common neoplasm affecting women in their reproductive age. It is estimated that up to 77% of women develop UF in their life. UFs are one of the leading causes of hospitalisations for gynaecological disorders and are the most frequent reason for hysterectomy. According to relevant literature, 40%-60% of all the hysterectomies performed are due to the presence of UFs.

NCT00339547
The proposed study is designed to estimate the proportion of 35-49 year-old women in a large urban health plan who have had fibroids. The membership of the health plan is approximately 45% black, so estimates for black and white women can be compared. Risk factors for the condition will be studied, and uterine tissue from women having hysterectomies or myomectomies will be studied to identify genetic, hormonal, and protein mediators of tumor growth. A randomly selected sample of about 1800 women age 35-49 who are members of the George Washington University Health Plan will be invited to participate. Presence of leiomyomas for premenopausal participants with no prior diagnosis of leiomyoma will be determined by an ultrasound examination. Presence of leiomyomas for premenopausal women who report a prior diagnosis of fibroids will be determined by ultrasound evidence in their medical record when available, and by self-report when not available. History of fibroids in postmenopausal women will be based on pathology records for those with surgical menopause and on radiology records or self-report for the small number of naturally postmenopausal women. Estimates of the proportion who have or have had fibroids will be compared for blacks and whites. To examine risk factors for leiomyoma we will conduct a case-control analysis. Cases will be those women identified with leiomyoma from the random sample, supplemented by women in the same age range who have hysterectomies or myomectomies during the study period and hose excised uteri show evidence of fibroids on standard pathology examination. Women from the random sample with ultrasound or pathology evidence showing no uterine fibroids will constitute the control group. Controls will be compared to cases grouped by size of largest fibroid and grouped by clinical. A telephone interview and self-administered questionnaire will provide information on demographic factors, medical history, dietary intake, reproductive history, life style factors, and occupational/environmental exposures. Blood will be collected from premenopausal women to measure lipids, insulin, and potential susceptibility genes. Urine will also be collected from premenopausal women early in their menstrual cycles to measure gonadotropin levels. Blood pressure, heart rate, weight, height, and waist-to-hip ration will be measured. Tissue from surgical specimens will be use by collaborators at NIEHS to measure cell proliferation and apoptosis, genetic factors, estrogen and progesterone receptor levels, protein markers of estrogen action, and growth factors.

The purpose of this study is to evaluate the efficacy of Relugolix (TAK-385) 40 mg administered orally once daily for 12 weeks, compared with leuprorelin injection (once every 4 weeks, 1.88 mg or 3.75 mg subcutaneously \[SC\]/time) in patients with uterine fibroids.
NCT01285960
The purpose of this study is to evaluate the safety and ablation efficacy of the ExAblate UF V2 System when treating symptomatic uterine fibroids. The ExAblate System is a medical device that involves a focused ultrasound system and an MRI scanner. ExAblate delivers a pulse of focused ultrasound energy, or sonication, to the targeted tissue. In this particular study, the targeted tissue is uterine fibroids. Each sonication is used to heat small spots in the fibroid much like a magnifying glass can be used to focus light to heat a spot. The heat created kills a portion of the fibroid with the goal of decreasing or eliminating uterine fibroid-related symptoms. Repeated sonications are performed until the entire fibroid is treated or the treated volume is determined to be appropriate. The ExAblate system is commercially approved in the United States to treat symptomatic uterine fibroids. The ExAblate UF V2 System is an experimental device and is being investigated in this study. While similar to the commercial system, the ExAblate UF V2 device includes the following major changes, among others, which are intended to improve device performance and safety: * Up and down movement of the ultrasound transducer, in an attempt to improve fibroid treatment by moving the ultrasound focal point within the targeted fibroid. * Ultrasound energy can be turned off for a specific area in an attempt to minimize amount of energy passing through sensitive areas of the body.
