SpaceOAR Hydrogel is intended to temporarily move the rectal wall away from the prostate during the course of radiotherapy treatment for prostate cancer, and in creating this space it is the intent of SpaceOAR Hydrogel to reduce the radiation dose affecting the rectum.

SpaceOAR Hydrogel contains polyethylene glycol (PEG). As with any medical treatment, there are some risks involved with the use of SpaceOAR Hydrogel. Potential complications associated with SpaceOAR Hydrogel include, but are not limited to: pain associated with injection, pain or discomfort from the hydrogel, site inflammation, infection (including abscess), inability to urinate, urgent need to urinate, constipation, rectal muscle spasm, damage to lining of rectum, ulcers, fistula (a hole between rectum and bladder, urethra, or skin below the scrotum), perforation (hole in prostate, bladder, urethra, rectum), necrosis (dead tissue), allergic reaction (local reaction or more severe reaction, such as anaphylaxis), embolism (blood vessel blockage is possible and may happen outside of the pelvis, potentially impacting vital organs or legs), fainting, and bleeding. Please talk to your doctor about the risks and benefits related to using SpaceOAR Hydrogel. If one or more of these complications occur, you may need medical treatment or surgery. URO-1288805-AA
