What are Gold Seeds (fiducial markers)?
Gold seeds (fiducial markers) are tiny seeds inserted into the prostate to help locate the position of the prostate during radiotherapy planning and treatment. The seeds are inserted under anaesthetic and via transperineal ultrasound guidance (the same procedure for transperineal biopsy of the prostate).
This procedure requires a general anaesthetic and is performed on a day case basis. You must arrange to have a family member or friend drive you home.
In some instances, during seed insertion, you may also have a temporary spacer inserted between your prostate and rectum prior to receiving radiation treatment. This is to keep your rectum safe.
