High intensity focused ultrasound (HIFU) is a type of cancer treatment that uses special high intensity ultrasound energy to heat and destroy cancer cells in your prostate.
You will meet the surgeon carrying out your procedure to discuss your care. It may differ from what is described here as it will be designed to meet your individual needs.
HIFU treatment uses high intensity ultrasound energy to heat and destroy cancer cells in your prostate gland.
Currently, HIFU is only used in clinical trials for men with localised prostate cancer (cancer that hasn’t spread outside of the prostate). This is because there isn't enough evidence on how well it works to recommend its use in all men with prostate cancer. The National Institute for Health and Care Excellence (NICE) recommends that HIFU is used in clinical trials so that longer term data can be collected.
HIFU is also being investigated in clinical trials in men with prostate cancer that has come back after radiotherapy treatment.
If you have an enlarged prostate and your urologist (a doctor who specialises in identifying and treating conditions that affect the urinary system) recommends you have HIFU, he or she may offer you another type of treatment beforehand to shrink the gland. For example, hormone therapy, or a procedure called transurethral resection of the prostate (TURP).
The type of treatment you have for prostate cancer will depend on whether the cancer has spread, and if so, how much. If you're invited to take part in a clinical trial for HIFU, your surgeon will tell you about the other treatment options available. Alternative treatments for prostate cancer include:
Your surgeon will explain how to prepare for the procedure.
You may have an enema the morning of your procedure. An enema is a liquid that is injected into your rectum (back passage) to empty your bowel.
HIFU is usually done as a day-case procedure under general anaesthesia. This means you will be asleep during the procedure. Alternatively, you may be given a spinal or epidural anaesthetic. This completely blocks pain from your waist down and you will stay awake during the procedure. Your surgeon may also give you a sedative to help you to relax.
If you're having a general anaesthetic, you will be asked to follow fasting instructions. This means not eating or drinking, typically for about six hours beforehand. However, it's important to follow your surgeon's advice.
Your surgeon will discuss with you what will happen before, during and after your procedure, and any pain you might have. This is your opportunity to understand what will happen, and you can help yourself by preparing questions to ask about the risks, benefits and any alternatives to the procedure. This will help you to be informed, so you can give your consent for the procedure to go ahead, which you may be asked to do by signing a consent form.
You may be asked to wear compression stockings to help prevent blood clots forming in the veins in your legs. You may need to have an injection of an anticlotting medicine called heparin as well as, or instead of, wearing compression stockings.
HIFU takes up to three hours. However, the exact time your procedure will take depends on the size of your prostate and how much of it is being treated.
Once you have been anaesthetised, your surgeon will pass a lubricated probe into your rectum. The probe will give out a beam of ultrasound. Your surgeon will focus the beam so that it heats and destroys the area of prostate tissue where there is cancer. The probe is guided by precise and sophisticated software to ensure only the desired areas of your prostate are targeted.
You may need to rest until the effects of the anaesthetic have passed. If you had a spinal anaesthetic, it may take several hours before the feeling comes back into your legs. You may need pain relief to help with any discomfort as the anaesthetic wears off.
You will have a catheter (a fine tube) to drain urine from your bladder into a bag. The catheter may pass out through either your penis or through a small cut in your abdomen (tummy). The catheter may be left in place for up to two weeks, but this can vary.
You will usually be able to go home when you feel ready. A nurse will give you some advice about how to manage your catheter at home and may give you an appointment to return to hospital to have it removed. You will need to arrange for someone to drive you home. Try to have a friend or relative stay with you for the first 24 hours after your procedure.
General anaesthesia temporarily affects your co-ordination and reasoning skills, so you must not drive, drink alcohol, operate machinery or sign legal documents for 24 hours afterwards. If you're in any doubt about driving, contact your motor insurer so that you're aware of their recommendations, and always follow your surgeon’s advice.
Your surgeon may prescribe a course of antibiotics to help prevent you developing an infection.
If you have been prescribed antibiotics, it's important to complete the full course.
If you need pain relief, you can take over-the-counter painkillers such as paracetamol or ibuprofen. Always read the patient information that comes with your medicine and if you have any questions, ask your pharmacist for advice.
As with every procedure, there are some risks associated with HIFU. We have not included the chance of these happening as they are specific to you and differ for every person. Ask your surgeon to explain how these risks apply to you.
Side-effects are the unwanted but mostly temporary effects you may get after having the procedure. Side-effects of HIFU include:
Contact the hospital or your GP if you have:
Complications are when problems occur during or after the procedure. The possible complications of HIFU include the following.
It’s important to remember that there isn't as much information about all the side-effects and complications of HIFU treatment compared with other treatments so this list may not cover everything. Speak to your surgeon for more information.
