Without the presence of SpaceOAR hydrogel, high dose radiation is more likely to reach the rectum.

SpaceOAR hydrogel provides space between the rectum and the prostate, reducing high dose radiation to the rectum.

SpaceOAR is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of SpaceOAR hydrogel to reduce the radiation dose delivered to the anterior rectum.  The SpaceOAR hydrogel is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment.  It is completely absorbed by the patient’s body over time.  

Clinical data comparing patients with and without SpaceOAR hydrogel demonstrated the benefits of SpaceOAR hydrogel to include reduction of rectal toxicity resulting in improved bowel function, improvements in urinary function, and a higher likelihood to maintain sexual function.  

Potential complications associated with SpaceOAR hydrogel include but are not limited to pain associated with SpaceOAR hydrogel injection; pain or discomfort associated with SpaceOAR hydrogel, needle penetration of the bladder, prostate, rectal wall, rectum, or urethra; injection of SpaceOAR hydrogel into the bladder, prostate, rectal wall, rectum, or urethra; local inflammatory reactions; infection; injection of air, fluid or SpaceOAR hydrogel intravascularly; urinary retention; rectal mucosal damage, ulcers, necrosis; bleeding; constipation; and rectal urgency.

Is SpaceOAR Hydrogel Safe?

SpaceOAR hydrogel is made of two liquids that when combined form a soft gel-like synthetic material that is mostly made of water. Because of its water content it is called a hydrogel. The material that the SpaceOAR hydrogel is made from has been used in other implants such as surgical sealants used on the eye, brain and spine. Studies have shown that the material is biocompatible and can be used safely in the body. SpaceOAR hydrogel is commercially available in the United States and approved in countries outside the United States.


Frequently Asked Patient Questions

Why Should I Have SpaceOAR Hydrogel?

The goal of radiation therapy is to maximize radiation to the prostate and to avoid radiating surrounding normal tissue. The prostate and rectum are very close and are only naturally separated by a small space. Due to this closeness, prostate radiation therapy can accidentally cause damage to the rectum. SpaceOAR hydrogel is a gel-like material that temporarily moves the rectal wall away from the prostate during radiotherapy. By separating the prostate from the rectum, SpaceOAR hydrogel reduces radiation dose delivered to the rectum and may eliminate or reduce damage to the rectum. It may also allow your doctor to enhance radiation treatment to your prostate to better target the cancer or to reduce the total number of treatment sessions.

Does my Doctor Recommend SpaceOAR Hydrogel?

Many radiation oncologists, urologists and interventional radiologists across the United States recommend SpaceOAR Hydrogel for their prostate cancer patients. Use our Find a Doctor Tool to locate one near you or ask your doctor.

"I would definitely recommend SpaceOAR. For me it has had very little consequence, either the day of the treatments, the weeks and months afterward, several years afterward."
