Focused ultrasound destroys fibroids with an intact uterus
Focused Ultrasound Therapy is a non-invasive, outpatient procedure, which uses high doses of focused ultrasound waves (HIFU) to destroy uterine fibroids without affecting any of the surrounding tissue.
The focused ultrasound energy is directed at a small volume of the fibroid, raising its temperature high enough to cause thermal ablation (killing of the cells) without impacting other tissues. Pulses of energy are repeated until the entire fibroid is treated.
Procedure
The patient lies on her stomach on a table.
After detailed planning, high energy focused ultrasound waves heat a small spot in the uterine fibroid to a temperature of up to 85oC. During the pulse or sonication, which lasts about 15 seconds, the doctor monitors the progress and reviews temperature-sensitive images.
Since each sonication treats a very small volume, this process will be repeated until the required volume is treated, typically about 50 times. The procedure lasts about 1-2 hours depending upon the size and number of fibroids treated.
Following the treatment, the body gradually removes the treated tissue over a period of months, providing symptom relief.
Experience during treatment
Before treatment you are given a sedative and pain medication to help you relax. You lie on a patient table and are made comfortable before starting treatment. Your clinical team will be in the room. The doctor will inform you when images are being acquired (scanning) and when the system is sonicating (treatment).
During treatment, it is normal to feel a warming sensation in the pelvic region. You will be given a safety stop button that allows you to immediately stop the sonication if the treatment becomes painful.
You are conscious the entire time and provide feedback during the procedure to the physician. Afterwards you'll be asked to rest for a few hours in the clinic, while the mild sedation wears off. Then you'll be able to go home and resume normal activity.
Are you a candidate for HIFU?
If you require treatment for your fibroid related symptoms, but want to avoid surgery and preserve your uterus, consult your doctor, who will ask you questions about your fibroid symptoms, general health and medical history. You will also have routine blood work, an internal gynecological examination and MR imaging of your fibroids. Based on this information your doctor will decide if you are a candidate for HIFU.
How do I find out more about the procedure?
I Contact the clinical coordinator at one of the sites under treatment centers. The clinical coordinator will explain the screening procedure and help you determine if HIFU is the right choice for you. The following procedure usually takes place once you call the clinical coordinator:
1. Initial telephone conversation: to provide more details on what the procedure entails and answer any questions you may have on the procedure. Information about insurance coverage and/or clinical trials may also be discussed. The clinical coordinator can send you a patient guide and additional information about the procedure.
2. Preliminary screening: if HIFU is an option you wish to consider, the clinical coordinator will set up a preliminary screening for you to determine if you are a potential candidate for HIFU.
3. MRI screening: once you have been determined a potential candidate, you will be invited for an MRI exam. This is called the "Screening Exam" to determine if your fibroids are amenable for treatment. If your fibroids are treatable by HIFU (meaning that they are reachable by the system), these MR images will also aid your physician in preparing a treatment plan for your fibroids.
4. Scheduling treatment: If you are eligible for the treatment, your clinical coordinator will then arrange a time and date for you to be treated, as well as provide you with instructions on how to prepare for the procedure. The clinical coordinator will also explain post-procedure follow-up and expectations.
