HIFU Frequently Asked Questions
What is HIFU?
HIFU stands for high intensity focused ultrasound, which is a minimally invasive technique for treating disease with precise, focused ultrasound waves that, when delivered, raise the temperature of the target tissue to nearly 195 degrees Fahrenheit in 2-3 seconds. This rapid-firing heat destroys the targeted tissue but leaves the surrounding tissue intact.
What is HIFU with the Sonablate® 500?
The Sonablate 500 (“Sonablate”) is medical device designed to treat prostate cancer and benign prostatic hyperplasia (“BPH”) with HIFU energy. The Sonablate captures real-time images of the prostate gland, allowing the physician to create a customized treatment plan for each patient. The physician then uses the Sonablate to deliver the ultrasound energy to extremely small target sites, or focal points, throughout the prostate gland.
HIFU with the Sonablate (“Sonablate HIFU”) is a minimally invasive, outpatient treatment choice for prostate cancer; it does not involve surgery or radiation.
How exactly does Sonablate HIFU treat prostate disease?
Since HIFU destroys tissue at each targeted focal point throughout the prostate, the entire gland is ablated at the conclusion of the procedure, while healthy structures outside the gland remain unharmed. HIFU uses non-ionizing, or clean, energy so the procedure may be repeated if necessary without damaging other tissue.
What are the results of the Sonablate HIFU treatment?
Sonablate HIFU has been used outside the United States for more than 10 years and international published studies show promising results as a cancer treatment that may well reduce risk for significant side effects, such as incontinence and impotence, often common with more aggressive modalities.
What are the recovery times and side effects of Sonablate HIFU for prostate cancer?
Patients can typically return to their normal lifestyle within a few days after the 2-4 hour procedure. Recovery involves wearing a catheter for approximately 2-3 weeks (varies according to each patient). All medical procedures have risks and benefits; all potential side effects and complications should be discussed with a physician prior to undergoing any procedure.
Does HIFU treat only the cancer cells? How?
Standard Sonablate HIFU treats the entire prostate gland by targeting tissue in overlapping treatment zones. The tissue is heated rapidly in targets, also known as lesions, throughout the entire gland until it is completely ablated.
Focal HIFU, on the other hand, involves treating only the cancerous part of the prostate with HIFU. Focal HIFU may be suitable for patients who have a single tumor within the gland or for patients with multiple tumors that all reside on the same side of the gland.
What is the history of HIFU and how long has it been used?
Research on HIFU began in the 1950s at Indiana University (IU) in Indianapolis, IN. In 1994, Dr. Michael Marberger and Dr. Stephan Madersbacher performed the first human prostate cancer study at the University of Vienna in Austria using the Sonablate® 200. They treated 29 human prostates in the body before performing a radical prostatectomy in order to see if the energy delivered was enough to destroy the targeted tissue. The study found that treatment could be performed safely and be repeated if necessary.

Is Sonablate HIFU unique?
Scientists have engineered the Sonablate in an effort to provide a customized, effective and safe treatment. Some unique Sonablate features include:
Where is Sonablate HIFU available now?
The Sonablate 500 is approved for investigational use within the U.S. and is being studied for the treatment of prostate cancer in clinical trials in the U.S. The FDA has made no decision as to the safety or efficacy of the Sonablate 500 for the treatment of prostate cancer. Currently, the device is available for the treatment of prostate cancer outside the U.S. in more than 30 countries.
Through International HIFU, one of US HIFU’s subsidiaries, U.S. patients and physicians travel each month to gain access to the technology in nearby offshore locations where it is already approved or authorized and available, including Nassau, Bahamas; Cancun and Puerto Vallarta, Mexico; Bermuda; and Toronto, Niagara Falls, Montreal and Winnipeg, Canada.
Sonablate HIFU can be found in additional areas such as Argentina, Australia, Brazil, China, Dominican Republic, Europe (Austria, France, Germany, Hungary, Italy, Romania, Russia, Spain, United Kingdom) India, Iran, Japan and Vietnam.
