SpaceOAR® System – Rectal Protection for Prostate Cancer Radiation Therapy Patients


Dr. Thomas Tarter, Urologic Oncologist at Cancer Care Specialists of Illinois, now offers a SpaceOAR procedure to protect prostate cancer patients from the negative effects of radiation therapy.

The SpaceOAR procedure is performed in office by Dr. Tarter at the Cancer Care Center of Decatur. The procedure is available to all Urologic Oncologists, Clinics and Hospitals to protect their patients before undergoing radiation therapy for prostate cancer at their respective locations.

To find out if SpaceOAR is right for you, talk to your radiation doctor and schedule an appointment with Dr. Tarter. Dr. Tarter performs the SpaceOAR procedure before radiation therapy begins. Following the procedure, all radiation therapy is managed by your radiation doctor.

Because of the close proximity of the prostate to the rectum, prostate radiation therapy typically results in some radiation hitting the rectum, which can sometimes cause side effects, such as pain during bowel movements, rectal urgency, bleeding or loose stools during or after radiation treatment. That’s why the rectum is called the Organ At Risk (OAR) during prostate radiation therapy.

SpaceOAR System reduces rectal injury in men receiving prostate cancer radiation therapy by acting as a spacer – pushing the rectum away from the prostate and out of the high dose radiation region.

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 patient’s urine — leaving nothing behind.

SpaceOAR System has been has been clinically proven and studied in a US Clinical Trial and is FDA cleared for sale in the US.
