What is SpaceOAR™ Hydrogel?
SpaceOAR Hydrogel is an absorbable hydrogel that temporarily creates space between the prostate and the rectum, reducing the radiation dose delivered to the rectum during prostate radiation therapy.
Frequently Asked Questions
Why should I have SpaceOAR Hydrogel?
When treating prostate cancer patients with radiation therapy, the goal is to kill the cancer cells while avoiding damage to surrounding healthy tissue. The prostate is next to the rectum and naturally separated by a small space. Due to the proximity, prostate radiation therapy can unintentionally cause damage to the rectum, which can lead to issues with bowel function. The “OAR” in SpaceOAR stands for “organ at risk,” and with radiation therapy to the prostate, this organ is the rectum.
How will SpaceOAR Hydrogel help me?
By acting as a spacer, the hydrogel temporarily moves the rectum a half inch (1.3 cm) away from the prostate. By separating the prostate from the rectum, SpaceOAR Hydrogel reduces the radiation dose delivered to the rectum and may eliminate or decrease damage.
Where is the procedure done and how long does it take?
SpaceOAR Hydrogel can be implanted as an outpatient procedure in a hospital, surgery center, outpatient clinic or doctor’s office prior to the start of radiation treatment. It is typically not a lengthy procedure.
What is it made of?
SpaceOAR Hydrogel is made up of two liquids that when combined form a soft gel material that is mostly made of water. The material that the SpaceOAR Hydrogel is made from has been used in other implants such as surgical sealants used in the eye, brain and spine.
How long will SpaceOAR Hydrogel remain in my body?
SpaceOAR Hydrogel stays in place, separating your prostate and rectum, for about 3 months. After about 6 months, the hydrogel is naturally absorbed into the body and removed in your urine.
