Single blinded randomized controlled study of symptom improvement after uterine artery embolization (UAE) versus ultrasound guided percutaneous/transvaginal microwave ablation, evaluated by validated questionnaires. Adenomyosis is a benign condition causing pain and bleeding disorders in many women. Hysterectomy has historically been the golden standard for treatment as well as (postoperatively) diagnosis of the disease. In accordance with refined diagnostic tools such as ultrasound and/or MRI, minimally invasive treatments for adenomyosis are being explored. We plan to compare two minimally invasive techniques: embolization of the uterine artery (a commonly used procedure) and microwave ablation of adenomyotic tissue (previously only in clinical use in China).
