Focused Ultrasound Therapy
Focused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with adenomyosis. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces precise ablation (thermal destruction of tissue) enabling adenomyosis to be treated without surgery.
The primary options for treatment of adenomyosis include medication and surgery.
For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost and with a shorter recovery time. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary. The treatment has the potential to preserve fertility, because the uterus is not removed. Case studies have reported that women have conceived and had healthy babies after focused ultrasound.
A clinical trial is underway in Finland that is assessing focused ultrasound to treat adenomyosis as well as the impact for fertility after the procedure.
Regulatory Approval and Reimbursement
Several companies have approval to treat adenomyosis in Europe, Russia, China, Korea, the Middle East, and Taiwan.
To the best of our knowledge, focused ultrasound treatment of adenomyosis is not universally reimbursed by medical insurers in the US.
