Transmucosal Uterosacral Electrical Stimulation for Pelvic Pain Relief

This study will test whether gentle electrical stimulation to nerves near the uterus can reduce pelvic pain after uterine fibroid embolization. The investigators hypothesize that participants receiving active TUNES stimulation will experience lower pain levels and improved early recovery compared to those receiving sham stimulation or standard care.

HIFU Versus Myomectomy for the Treatment of Symptomatic Uterine Fibroids

The goal of this clinical trial is to learn if High-Intensity Focused Ultrasound (HIFU) is as effective as myomectomy for treating symptomatic uterine fibroids in women aged 18 to 50. The main questions it aims to answer are: Is HIFU as effective as myomectomy in improving quality of life for women with uterine fibroids? How do the recovery times and complications compare between HIFU and myomectomy? Researchers will compare the outcomes of women receiving HIFU treatment to those undergoing myomectomy to see if HIFU offers similar or better results with fewer complications. Participants will: Undergo an initial medical assessment, including ultrasounds and blood tests. Receive either HIFU treatment or myomectomy based on random assignment. Complete questionnaires about their symptoms and quality of life before treatment and at follow-up visits (3 and 6 months post-treatment). Be monitored for any complications and recovery progress during follow-up.

Hugo™ Robotic-Assisted Surgery (RAS) System in Gynecological Subjects (Embrace Gynecology)

The purpose of this research is to evaluate the safety and performance of the investigational Medtronic Hugo™ Robotic Assisted Surgery (RAS) system when used during hysterectomy procedures, including patients being treated for cancer.

Artificial Intelligence for the Intra-procedural Assessment of Uterine Artery Embolization

Uterine artery embolization is a minimally invasive treatment for symptomatic uterine fibroids, but intra-procedural assessment of embolization adequacy currently relies on subjective angiographic criteria. This study evaluates a proprietary angiographic analysis software (AQ-VERO) that extracts quantitative time-to-density perfusion metrics in real time. The study aims to (1) validate the accuracy and reproducibility of AQ-VERO during uterine artery mebolization, and (2) develop an AI-based decision support system using AQ-VERO-derived metrics to improve objective intra-procedural assessment of treatment endpoints.

Comparing the Efficacy of TU-LESS and vNOTES for Hysterectomy of Enlarged Uterus

Enlarged uterus is frequently encountered in clinical practice, and its incidence due to conditions such as adenomyosis, uterine fibroids, and other gynecological disorders has steadily increased over the years statistically. For example, greater healthcare awareness has led to more frequent early diagnoses of these conditions, contributing to the observed rise in incidence. Additionally, increasing life expectancy results in more women reaching the perimenopausal and postmenopausal stages, during which conditions like uterine fibroids and adenomyosis become more prevalent. For these women, hysterectomy (removal of the entire uterus) is often the recommended option of treatment. With advances in surgical techniques over recent decades, there has been a notable shift from traditional open abdominal surgeries to minimally invasive approaches. Laparoscopic surgery has been widely adopted, significantly reducing the size and number of incisions required, thereby promoting faster recovery, minimizing postoperative pain, and reducing the risk of complications. However, conventional multi-port laparoscopic hysterectomy still presents certain challenges, such as large uterus extraction following resection, and concerns about healing of incisions. In contrast, innovative techniques like Transumbilical Laparoendoscopic Single-Site Surgery(TU-LESS) and Transvaginal Natural Orifice Transluminal Endoscopic Surgery(vNOTES) both take advantage of natural anatomical openings to achieve minimal or no visible scarring. Studies demonstrate that these techniques provide superior outcomes in terms of reduced pain, faster recovery, and quicker return to daily activities compared to traditional multi-port laparoscopic approaches. Yet a direct comparison of the efficacy of these two methods in real-world, particularly for enlarged uterus, remains inconclusive. Thus this study aims to evaluate and compare the outcomes of these two techniques in patients with enlarged uteri. Participants will be randomly assigned to receive one of the two surgical approaches, ensuring an unbiased comparison of the efficacy of the procedures in terms of healing status and recovery time.

POPQ Associated With Total Laparoscopic Hysterectomy

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

Anatomopathological Evaluation of a New Ultrasound-guided Transuterine Vaginal Biopsy Technique in Uterine Fibromatous Disease

The benign uterine fibroid is part of the broader term uterine smooth muscle tumour, which also includes malignant myometrial tumours (MSTs) of varying malignancy (uterine sarcoma, cellular fibroid, STUMP (uterine smooth muscle tumours of uncertain malignant potential)). Magnetic resonance imaging (MRI) is the most effective test for distinguishing a fibroid from a TMM, but its reliability is limited. This leads to inappropriate management in a number of situations. The first is the risk of overtreatment by performing surgery for a suspected TMM on MRI in a patient with few or no symptoms and a final histological diagnosis of fibroid. The second is the risk of unsatisfactory or even harmful cancer surgical treatment in a symptomatic patient with a reassuring MRI diagnosis but a final histological diagnosis of TMM. Finally, there is the possibility of treating a lesion labelled as a fibroid on MRI with an alternative technique (embolisation, radiofrequency, HIFU) when it is in fact a TMM, thereby delaying appropriate treatment and worsening the prognosis. Ultrasound-guided transuterine vaginal biopsy (ETVB) is an innovative and promising minimally invasive technique for preoperative anatomopathological diagnosis. It would make it possible to obtain a histological diagnosis without the need for surgery, thereby avoiding the inappropriate management described above. The aim of this study is to validate an innovative minimally invasive surgical technique (BVTE) for the diagnosis of uterine smooth muscle tumours by biopsy, to assess the complications associated with the technique and any potential adverse effects, and to evaluate the feasibility of the technique in current practice.

Investigating the Optimal Remifentanil and Dexmedetomidine Concentration for Uterine Fibroid Ablation

This clinical trial aims to find a better drug concentration of Remifentanil in Uterine Fibroid Ablation. The main question it seeks to answer is: \[primary hypothesis 1\] Remifentanil concentration of 2.0 ng/mL provides better pain control in Uterine Fibroid Ablation. There is a comparison group in this study: Researchers will compare Remifentanil concentration of 1.0 ng/mL to see if provides similar pain control with fewer side effects. Participants will be separated into two groups, one group with a Remifentanil concentration of 2.0 ng/mL and the other 1.0 ng/mL. During uterine fibroid ablation, the patient\'s pain index will be recorded (using a Visual Analogue Scale (VAS) of 0\~10 points). We will also record vital signs during the procedure.
