Brachytherapy is a form of radiation treatment in which a radioactive source is placed directly into the target (in this case the prostate gland). It can safely deliver a higher dose of radiation precisely to its target while minimizing the dose to the surrounding normal tissue. It is normally given in conjunction with a course of external beam radiation treatment with the aim of curative treatment for some types of prostate cancer. When administered with external beam radiotherapy, it is given in two parts, before and during the course of external beam radiotherapy with a gap of two weeks between implants.

What will happen to me during brachytherapy treatment?

If brachytherapy has been recommended by your radiation oncologist, you will be booked to have your first implant before you start external beam radiation therapy.

A staff member will contact you by phone with a date and time for your treatment.

The procedure involves several members of our radiation therapy team. These include your radiation oncologist, an anaesthetic doctor, a registered nurse, two radiation therapists and a physicist.

On the day of your brachytherapy treatment, expect to be in the radiation oncology department from 7.30am to 4.00pm.

The day before your brachytherapy implant you will be required to drink a bowel cleaning preparation. This ensures you have an empty rectum for the implant the following morning. Make sure you have been seen by one of our nurses at least one week before the implant. He or she will provide you with the brachytherapy preparation instructions.

Your brachytherapy treatment is performed in two stages in our operating theatre.

Insertion of needles and dose optimisation

This stage takes about one hour.

  • Under anaesthetic, you will be positioned on the operating table.
  • Your knees will be raised and held steady in stirrups.
  • Your perineal area is cleaned with an anti-septic solution.
  • A urinary catheter is inserted via the penis into the bladder.
  • An ultrasound probe is inserted into your (empty) rectum. With ultrasound guidance, 18 to 20 hollow round-ended  needles are inserted through the template and skin into your prostate.
  • The needles are held firmly in place by a plastic template which is sutured to your perineum (the skin between your scrotum and anus) until the treatment time.
  • After this, your legs are placed back down on the bed and you will be transferred to our CT scanner.
  • The CT scan is used to localize the needles, the prostate, and the rectum, allowing us to plan the optimal dose distribution in 3 dimensions.

Your brachytherapy treatment

This stage takes about 40 minutes. The actual treatment will take approximately 20 minutes. Prior to treatment delivery our team will perform quality assurance checks on your treatment plan and delivery. This will normally take another 20 minutes.

Once the treatment had been planned, the radiation therapists will check all the treatment information and take you into the brachytherapy treatment room.

The radiation therapists will then connect the needles to the machine that contains the radioactive source.

Once connected, the radiation therapists will leave the treatment room so they can switch on the treatment machine. The machine moves the radioactive source by remote control to the needles inside your prostate.

The radiation therapists will be watching you at all times using cameras and they can also hear you. You shouldn’t experience any discomfort from the treatment. Once it’s done, the hollow needles and template are removed by your radiation oncologist.

The urinary catheter is kept in until the urine is less bloodstained and is removed prior to you leaving the department.

Side effects

Side effects will vary from patient to patient. They may include:

  • Small amount of bleeding (small clots in your urine)
  • Inflammation of the prostate
  • Diarrhoea and/or cystitis (burning while urinating). These should settle down within a week or so, but may flare up again when you start your external beam treatment.
  • Possible infection

Should you have any concerns or trouble urinating, please contact your Radiation Oncologist
