    Spacing procedures are performed in hospitals, outpatient clinics, or doctors' offices prior to the start of radiation treatment.

    The procedure is similar to your prostate biopsy and may be performed under local, regional, or general anesthesia.

  • icon

    Barrigel is placed between the rectum and the prostate through the perineum.

  • icon

    Fiducial markers are small metal markers that can be placed in your prostate to help your treatment team line up the radiation beams. If your doctor determines fiducial markers are appropriate for you, Barrigel may be implanted at the same time.

    Following the procedure, you can expect to be monitored in recovery before being discharged.

  • icon

    Most patients continue with normal daily activities shortly after the procedure, although your doctor may ask you to refrain from heavy lifting and strenuous physical activity for a few days.

It's important to adhere to all of your doctor's pre-procedure preparation and post-procedure instructions.

Barrigel can be viewed clearly on transrectal ultrasound (TRUS), the imaging machine used to guide your doctor's placement during the procedure. This real-time visibility provides your doctor control and precision over the shape and placement of the spacer.1

Barrigel remains in place throughout the course of your radiation treatment, maintaining the space between your prostate and rectum until it is safely and fully absorbed by your body.1
