Frequently Asked Questions
1. How long has Sonablate® HIFU it been done? Where?
HIFU was originally researched in the United States almost 50 years ago. Focus Surgery, Inc., the developers of Sonablate®, introduced the first application for prostate disease in the early 1990s with the Sonablate® 200. In Europe, Asia and the Americas over 6,000 treatments have been done with the Sonablate®. The Sonablate® 500 is being studied in clinical trials for use in the treatment of prostate cancer in the United States and is not approved for use by the U.S. Food and Drug Administration. HIFU with the Sonablate® 500 is authorized for use for the treatment of prostate cancer in Canada, Argentina and the Dominican Republic. It is also available in the Bahamas and Mexico.
2. Is it a one time procedure or do I have to return for multiple procedures?
In most cases, HIFU with the Sonablate® 500 is a one time procedure that lasts approximately 1-4 hours depending on prostate size. It is considered an out-patient procedure meaning that the patient can be discharged after he or she has recovered from the anesthesia.
3. What should I expect after I have HIFU?
During the first one to two weeks after the procedure, a patient may experience very mild urinary symptoms such as frequency and/or urgency to void. In the first one to two months, a patient may pass an occasional small amount of blood or mucus-like materials which is normal. A urinary catheter is inserted after the procedure and must be kept in place for 2-3 weeks.
4. Is this a type of radiation like brachytherapy? Which one is a better minimally invasive procedure?
HIFU is completely radiation free. Unlike radiation, ultrasound energy is non-ionizing meaning it will not harm any tissue outside of the targeted area. Although both brachytherapy and HIFU are both considered minimally invasive, HIFU only requires one therapy session, in most cases.
5. During HIFU is the entire prostate destroyed or does the doctor only target the tumor or diseased area?
During the HIFU procedure the entire prostate gland will be ablated or destroyed. Because it can be very difficult to determine the exact location of the cancer or tumor within the prostate, the Sonablate® 500 is programmed to target the entire gland. This also minimizes the chance for recurrence.
6. How do I know if I am a candidate for HIFU? What are the qualifications?
Like most prostate cancer therapies, there is an “ideal” candidate for HIFU. HIFU is most effective for patients with early stage prostate cancer where the cancer is localized to the prostate. It is recommended that you discuss your individual medical records and history with a HIFU certified physician in order to confirm whether or not you are a candidate for HIFU.
7. Is this procedure repeatable?
Yes, HIFU with the Sonablate® 500 can be repeated if necessary. In most cases, Sonablate® HIFU is a one-time procedure, however, unlike radiation it will not prevent patients from having other treatments (radiation, cryotherapy etc) if needed.
8. What happens to the urethra during HIFU? Since it runs through the center of the prostate is it destroyed during the procedure?
During HIFU, the entire prostate is ablated, including the prostatic urethra. However, the urethra is derived from a different type of tissue (bladder squamous-type epithelium) rather than prostatic tissue (glandular, fibrotic and muscular) and does regenerate with time. While the urethra is an important anatomical structure, the sphincter and bladder neck are more important to maintaining the urinary function. During HIFU the sphincter and bladder neck are identified and avoided.
9. How long will I have to stay in the hospital?
HIFU is an out-patient procedure and does not normally require any hospital stay. The procedure usually takes 1-4 hours, depending on prostate size and recovery time is 2-3 hours. After recovery, the patient is discharged.
10. Where is the procedure available?
HIFU with the Sonablate® 500 is available in Argentina, Canada, Costa Rica, Mexico, South Africa, the Bahamas and the Dominican Republic. To find out more about HIFU in countries where its use is approved please call 1-888-874-4384 or visit www.InternationalHIFU.com.
