Frequently Asked Questions

1. What is HIFU?

HIFU is high intensity focused ultrasound. The technology has been developed as a curative treatment for localised prostate cancer.

2. How does HIFU work?

A transducer probe emits a powerful ultrasound wave that can be focused and concentrated to a point a small distance away from the probe.

This is similar to the way in which a magnifying glass can be used to focus the power of the sun's rays to a point, causing a burn.

The concentration of the HIFU beam can create maximum pressure at a point (the focal point), creating temperatures of between 85° and 100°C at this point.

It is indicated as a first choice therapy for localized prostate cancer in suitable patients.

3. Is the whole Prostate treated during this procedure?

Yes. The operating surgeon uses computer software to treat the prostate and the cancer within.

The HIFU beam is concentrated at different points within the prostate, in three dimensions, to ensure that destruction of the tissue is complete.

4. How long does the procedure take?

Depending on the size of the prostate, the average treatment takes 2-3 hours to complete.

The patient requires either a spinal anaesthetic or general anaesthetic for the duration of the procedure.

5. Can all prostate cancer be treated with HIFU?

No. The cancer must be localized within the prostate with no spread to surrounding organs. The prostate must not be too large, as this will make complete treatment difficult to carry out. The rectal lining and anatomy must be normal. This will affect how the ultrasound probe is placed and how well it works during treatment.

6. What happens after the procedure?

After discharge from hospital, the patient is advised to avoid driving for 2-3 days and also lifting or straining for two weeks. Normal activities may be otherwise resumed.

The patient has a regular PSA blood test every three months to ensure that the cancer has been treated effectively.
