In the treatment of localized prostate cancer, there are a number of increasingly effective treatments available for this common condition. Depending on the stage of cancer, age, and other medical problems, your urologist will help you make an informed decision on the best course of treatment. Each treatment option of course has its own risks and benefits. When choosing radiation treatment for prostate cancer, certain steps can be taken to minimize the risk of radiation injury to important organs that are very close to the prostate. One such treatment prior to undergoing radiation is the insertion of SpaceOAR™ Hydrogel in the space between the prostate and rectum. This gel creates an extra barrier that protects the rectum from receiving unnecessary radiation. When performed in the office, you may consider ProNox® as an added anesthetic during the procedure to reduce anxiety and enhanced comfort for a nominal fee.

WHAT IS SPACEOAR® HYDROGEL?

SpaceOAR Hydrogel is an absorbable gel material that creates a temporary space between the prostate and the rectum, potentially reducing radiation dose to the rectum during prostate cancer radiation. It separates the prostate and rectum and is naturally absorbed by the body in about six months.3 More than 100,000 patients worldwide have been successfully treated with SpaceOAR Hydrogel.7

WHY IS SPACEOAR® IMPORTANT TO PATIENTS?

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. SpaceOAR Hydrogel is a gel spacer that temporarily moves the rectal wall farther away from the prostate. By separating the prostate from the rectum, the radiation dose delivered to the rectum is reduced, which may lessen damage to the rectum. 

Clinical data demonstrated the benefits of SpaceOAR Hydrogel, including a reduction of rectal injury resulting in maintained bowel function and a higher likelihood to maintain urinary and sexual function.10

FAQs: SpaceOAR™ Hydrogel

SpaceOAR Hydrogel is made up of two liquids that, when combined, form a soft gel material mostly made of water. Studies have shown that the material is biocompatible, can be used in the body without causing injury or a reaction and can be safely absorbed by the body. 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.
SpaceOAR Hydrogel can be placed in a short visit in the office.
SpaceOAR Hydrogel can be used in all types of radiation therapy for the prostate.
Patients are usually able to go back to normal activities shortly after SpaceOAR Hydrogel is implanted.
SpaceOAR Hydrogel stays in place for about three months. After about six months, the hydrogel is naturally absorbed into the body and removed through urine.
SpaceOAR Hydrogel is covered by many insurance plans and is reimbursed by Medicare on a case-by-case basis. Patients should verify their benefits with their insurance company in advance of the scheduled procedure.
As with any medical treatment, there are some risks involved with the use of SpaceOAR Hydrogel. Potential complications 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.
