Boston Scientific SpaceOAR™ Hydrogel

Radiation Treatment Spacer

At a Glance

  • Provides fewer long-term side effects from radiation therapy
  • More likely to report maintenance of sexual function
  • Lower decline in urinary and bowel function

The Details

Radiation therapy can be extremely effective in treating prostate cancer, but as with any procedure, there are potential side effects. The prostate is next to the rectum. Due to the proximity, prostate radiation therapy can unintentionally cause damage to the rectum, which can lead to issues with bowel function.

SpaceOAR Hydrogel is designed to temporarily create space between the prostate and the rectum, reducing the radiation dose delivered to the rectum during prostate radiation therapy which may lessen damage to the rectum.

What to know about Boston Scientific SpaceOAR™ Hydrogel

How it Works

SpaceOAR Hydrogel is injected into place prior to the start of radiation treatment. Patients may be awake or asleep under general anesthesia for the procedure. SpaceOAR Hydrogel remains stable during radiation therapy and then is gradually absorbed by the body after radiation therapy has been completed.

Who’s it For?

SpaceOAR Hydrogel is an option for men who undergo radiation treatment for prostate cancer.


SpaceOAR Hydrogel provides space between the rectum and the prostate, reducing high dose radiation to the rectum. Control patients (patients who didn’t use SpaceOAR Hydrogel for prostate cancer radiation treatment) were 8x more likely to have a decline in bowel, urinary and sexual quality of life when compared to SpaceOAR Hydrogel patients at median of 3 years.
