Focused Ultrasound Therapy
Focused ultrasound is a noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with BPH. This novel technology focuses beams of ultrasound energy precisely and accurately on targets 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 BPH to be treated without surgery.
Advantages
The primary options for treatment of BPH include medication and invasive 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. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.
Clinical Trials
There is a clinical trial using the EDAP TMS system for the treatment of BPH in multiple sites in France.

Regulatory Approval and Reimbursement
There are four focused ultrasound systems approved in the US for the ablation (destruction) of prostate tissue: Sonablate Corp, EDAP-TMS, Insightec and Profound Medical. Sonablate Corp and EDAP-TMS use the transrectal approach with ultrasound guidance. Insightec’s device uses a transrectal approach guided by MRI. A transurethral, MRI-guided approach is manufactured by Profound Medical, and it is approved in Europe and in the US.
Treatment for BPH is approved in the US, Canada, China, Europe, India, Japan, Korea, Middle East, Russia, and South America. Insurance coverage varies, and many US companies may not cover this procedure.
