Adenomyosis is a relatively common benign uterine disease in women of childbearing age, the main danger is to cause gradually increasing menstrual pain, which can be accompanied by increased menstrual flow, as the disease progresses, usually the uterine wall will gradually thicken, the uterus gradually increases in size, the disease can cause infertility in severe cases. The main traditional gynecological cure for adenomyosis is hysterectomy. For conservative treatment of adenomyosis, there are not many methods and the efficacy is not considered satisfactory. For milder adenomyosis, symptomatic pain relief treatment during menstruation can be considered, try intrauterine cavity placement of drug ring. If the menstrual pain is significant, the pain medication is not effective, the drug ring is ineffective or fails, there is clear myometrial wall thickening or uterine enlargement, and the patient has the desire to preserve the uterus, then the application of ultrasound ablation therapy can be considered. The characteristics of ultrasound ablation technology for adenomyosis are: 1. Physical thermal ablation: it does not interfere with the patient’s endocrine secretion. 2. conformal ablation: it is applicable to the borderless and diffuse distribution of adenomyosis lesions, and can also treat larger uterus to obtain a higher ablation rate of lesions, thus obtaining a more significant symptom control rate and a lower symptom recurrence rate. In conclusion, ultrasound ablation is one of the more effective and less costly techniques to treat adenomyosis with uterine preservation, and many patients have benefited from it.
