Enhancing comfort for those receiving prostate radiation therapy
SpaceOAR hydrogel pushes the rectum out of the damaging radiation field

Getting radiation therapy for prostate cancer is a difficult experience. The risk of radiation complications is always present along with rectal pain.

To provide relief and protection, prostate cancer patients receiving radiation therapy can choose to receive a SpaceOAR hydrogel injection.

Hydrogel has been demonstrated as a safe and effective option in clinical trials in Europe and the US. It 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 trials in Europe and the US 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.

It is minimally invasive, and patients can be awake or under general anesthesia during the procedure. It is designed to remain stable during radiation therapy and is eventually absorbed by the body upon the completion of the therapy.

Dr. Choi provides SpaceOAR in his office, using the Pro-Nox gas system. Safely used in dental offices for years, patients receive a mixture of 50% oxygen and 50% nitrous oxide, making the procedure more comfortable and easing anxiety.
