Texas Urology Specialists Announces Use of SpaceOAR® Hydrogel

Request More Information

Texas Urology Specialists is pleased to announce the use of SpaceOAR hydrogel. Applied by Dr. Ashley Ross and Dr. Mitchell Moskowitz, SpaceOAR hydrogel is used for prostate cancer radiotherapy and acts as a protective spacer between the prostate and the rectum. It has been clinically proven to reduce the risk of side effects from radiation treatment.

Texas Urology Specialists focuses on the diagnosis and treatment of conditions of the urinary tract and the urogenital system. With locations in Dallas, McKinney and Plano, Texas Urology Specialists treat a wide array of urological conditions including prostate cancer.

“The use of SpaceOAR hydrogel is easy to implement, easy to conceptualize, and an effective method by which the toxicity of prostate cancer radiation can be further minimized,” said Dr. Ashley Ross, Urologist at Texas Urology Specialists.

In April 2015, SpaceOAR hydrogel received FDA clearance. In a prospective, randomized, multi-center clinical trial in the United States, patients treated with SpaceOAR hydrogel prior to prostate cancer radiation treatment demonstrated bowel, urinary, and sexual benefits through three years of follow-up. The study found that the patients that did not receive SpaceOAR hydrogel experienced a clinically significant decline in bowel, urinary, and sexual quality of life more often than patients that received SpaceOAR hydrogel.1,2 It is a minimally invasive outpatient procedure with local or general anesthesia. Patients can immediately resume their normal activities. The gel stays in place for approximately three months and is then naturally absorbed and cleared in the urine in about six months.

“Radiation therapy with SpaceOAR hydrogel offers these men the unique opportunity to have their cancer treated while continuing their daily routine and preserve their post treatment quality of life,” said John Pedersen, President and CEO of Augmenix, Inc. “We are excited that Texas Urology Specialists has adopted the SpaceOAR System.”

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.
