What Are the Results?

Over 7,000 men have been treated for localized prostate cancer with the advanced Sonablate® 500 HIFU system by over 200 of the top urologists at over 100 centers worldwide.  The system has been reported by these urologists to perform as follows:


For localized prostate cancer therapy:

Patients with Pre-Treat PSA:
Less than 10.0ng/ml  93%
10.0 – 20.0ng/ml 75%

5- Year Success Rate:

(for all risk groups)


Overall Success Rate:* 

*Sonablate® 500 with ver. 4 software and features only


Presentation by T. Uchida of Tokai University Hachioji Hospital, Tokyo, Japan at American Urology Association HIFU Users Meeting 2007 with three year follow-up data of 54 patients.



For salvage therapy of localized prostate cancer:

After EBRT: 
PSA Nadir < 0.5 after 3 months: 74% success
Overall Success rate: 78%

Quality of Life:

Studies show that Quality Of Life (QOL) factors did not change significantly for patients pre and post HIFU therapy*
