SpaceOAR Hydrogel is a PEG-based hydrogel designed to help reduce the radiation dose delivered to the rectum during prostate cancer radiation treatments.
When treating prostate cancer patients with radiation therapy, the goal is to destroy the cancer cells while avoiding damage to the surrounding healthy tissue.
Due to the close proximity between the rectum and the prostate, radiation therapy can unintentionally cause rectal toxicity.
The hydrogel spacer is designed to temporarily position the anterior rectal wall away from the prostate.
SpaceOAR Hydrogel is shown to help reduce the radiation dose planned to be delivered to the rectum during prostate cancer radiotherapy.1
Hydrodissection is a confirmation step of a perirectal spacing procedure. It confirms proper needle positioning and allows visualization of where the spacer will be injected.
Watch a SpaceOAR Vue™ full procedure under the local anesthesia technique with urologist Dr. Dean Laganosky.
“I would never do this procedure without hydrodissection. I think it is the safety stop and measure for a good gel placement. It ensures that the needle tip is right where you want it in the sweet spot of the perirectal fat.”

“Hydrodissection is actually the most important part of the procedure. It makes me have confidence that we’re injecting it into the correct space and that we’re not injecting the gel into the rectal wall or the bladder.”
