Prostate with SpaceOAR Hydrogel

Because of the proximity of the rectum to the prostate, prostate radiation therapy can cause unintended damage to the rectum, which can lead to fecal incontinence issues or other long-lasting side effects. These side effects can be a barrier for men who might otherwise seek radiation, but there are options available to help reduce some of these risks.

SpaceOAR Hydrogel is an absorbable gel that creates a temporary space between the prostate and the rectum, designed to reduce radiation dose to the rectum. It is inserted via a minimally invasive procedure and is naturally absorbed by the body in about six months.

SpaceOAR Hydrogel has been evaluated in clinical studies and has been shown to be safe and effective in reducing potential side effects of radiation therapy to the rectal area. In a randomized clinical study*, men who underwent radiation therapy without SpaceOAR Hydrogel were eight times more likely to experience a decline in bowel, urinary and sexual function when compared to men who underwent radiation therapy with SpaceOAR Hydrogel, at a median follow-up of three years.
