Most endometrial polyps are caused by endometrial hyperplasia, 80%-90% are benign lesions, some patients have symptoms, if there are no symptoms, only ultrasound findings of uterine thickening do not require treatment. If the patient has symptoms, such as increased menstrual flow, prolonged menstruation or even vaginal bleeding in the middle of the menstrual period, an examination is needed. After hysteroscopy, the diagnosis can be made by minimally invasive hysteroscopic endometrial polypectomy, which is very effective and causes little pain to the patient. After treatment, to prevent recurrence, you can place a Manned Ring, which is a ring that can release progesterone and inhibit endometrial hyperplasia. Therefore, endometrial polyps can be treated minimally invasively and there are subsequent treatments that do not require removal of the uterus.
