Dysfunctional uterine bleeding

Radiofrequency biothermal effect causes the endometrium to have the following effects: while scraping the endometrium, ablating the basal layer to the shallow basal layer of 2 ~ 3mm, making it shed and discharged, so as to achieve the purpose of treating functional uterine bleeding, without affecting the structure of myometrium and ovarian function. Because radiofrequency ablation is completed under the guidance of B-ultrasound, the operation is intuitive and easy to observe, without laparotomy, and no normal tissues will be removed, so as to completely preserve the integrity of the uterine and pelvic structures. It is a new breakthrough in the history of minimally invasive gynecology.

Functional bleeding is abnormal uterine bleeding caused by neuroendocrine dysregulation. The incidence of functional bleeding is 20% ~ 22%, of which 50% occurs in perimenopausal period. The main manifestations are: increased menstrual volume, prolonged menstrual period or irregular vaginal bleeding, which seriously affect the quality of life of women. In recent years, various treatments for the disease can temporarily relieve symptoms, but no breakthrough progress. RFAE uses an endometrial scraping knife to scrape the functional layer of endometrium and electrocoagulation to ablate the basal layer and superficial muscle layer, so as to cause irreversible degeneration, necrosis, shedding and discharge. On the premise of not interfering with the neuroendocrine function of the body and destroying the basic structure of the reproductive system, the problem of uterine bleeding can be fundamentally solved. RFAE should be carried out under the monitoring of B-mode ultrasound. The best time of operation is 3-5 days after menstruation or curetting, and the possibility of malignant lesions is excluded by pathological examination. After operation, uterine residual tissue was removed, oxytocin was administered to strengthen uterine contractions, anti-inflammatory and hemostatic treatment for 5-7 days.
