How does SpaceOAR Hydrogel Work?

SpaceOAR Hydrogel – Spacing Organs At Risk (OAR): Rectal Protection for Prostate Cancer Radiation Therapy Patients

SpaceOAR Hydrogel reduces rectal injury in men receiving prostate cancer radiation therapy (RT) by acting as a spacer – pushing the rectum away from the prostate.

With SpaceOAR Hydrogel
The SpaceOAR Spacer pushes the rectum away from the prostate, decreasing rectal injury during prostate RT.

A Little Space Makes a BIG Difference™

Placed between the prostate and rectum, SpaceOAR hydrogel pushes the rectum out of the high dose radiation region. Like prostate cancer cells, cells in the rectum are also damaged by the high dose radiation. That’s why the rectum is called the Organ At Risk (OAR) during prostate radiation therapy.

SpaceOAR hydrogel pushes the rectum out of the damaging radiation field. This may help prevent prostate radiation side effects

SpaceOAR Hydrogel Pushes the Rectum Out of the High Dose Radiation Field

The hydrogel spacer is injected during a minimally invasive procedure, and — once in place — patients typically can’t feel it. The hydrogel is safe and similar to other products used in brain surgery, cardiology and ophthalmology. It remains in place for 3 months during radiation treatment, and is then absorbed and leaves the body in the patients urine — leaving nothing behind.
