Radiofrequency ablation of fibroids under transcervical ultrasound guidance (SONATA®system) has been available in Switzerland since 2017. Under anaesthesia, a probe is inserted into the uterine cavity so that the fibroids can be localised and treated by heat. The heat treatment shrinks the fibroids in the weeks and months that follow.
The Sonata method is a relatively simple way to treat multiple symptomatic fibroids without an abdominal incision or injury to the uterus. Postoperative pain is rare. The method is also possible if you wish to have children.
