The Sonablate® HIFU Procedure

Before HIFU: My patients are typically given two enemas two hours prior to the procedure. It is very important that patients do not move during Sonablate® HIFU thus patients are generally given an epidural (spinal) anesthesia and light intravenous sedation.

During HIFU: There is no pain during treatment. I will insert a small probe into the rectum that emits ultrasound waves directly to the prostatic tissue. During the procedure, the Sonablate® 500 delivers real-time images of your prostate and the surrounding area giving me immediate and detailed feedback. Treatment time varies, but generally the procedure lasts a few hours, depending on the size of the prostate.

After HIFU: Immediately after Sonablate® HIFU procedure most patients typically spend one to two hours recovering at the treatment facility and then are discharged. At that time I will prescribe some basic medications, but most patients do not experience any pain after the procedure. A catheter will be inserted for few weeks to ensure the bladder empties properly. I encourage my patients to have their PSA checked three months after the procedure.

Effectiveness of the Sonablate® HIFU

HIFU has been studied extensively in Japan and Europe. Studies and presentations from outside the United States report that HIFU is a technique broadly comparable to standard therapies for the treatment for prostate cancer.2 A Japanese 3-year study of HIFU in patients who had a pre-HIFU PSA <10, had a biochemical disease free rate of 94%.3

Potential Side Effects and Complications

All treatments for prostate cancer carry some risk for potential side effects and complications. Side effects include frequency, urgency, mild discomfort or discharge in urinary stream. Studies performed outside the US report that less common side effects (these may be more severe) may also include urinary stricture, retention, incontinence, impotence and rectal fistula. As with any medical procedure, all potential side effects and complications should be discussed with a physician before undergoing therapy.
