What is a rectal shield?
It is a gel that’s placed between your prostate and rectum to move your rectum away from your prostate. This protects your rectum from radiation and reduces some side effects of radiation therapy. The rectal spacer will stay in place for 3 months. Then, it’ll be absorbed by your body and come out in your urine.
How effective is SpaceOAR?
Clinical test results Results showed that the SpaceOAR hydrogel was safe and effective. The average participant gained 1/2 inch of space between the prostate and rectum and had significant reduction in radiation dose to the rectum, resulting in significantly fewer rectal side effects.
What is a rectal spacer?
A rectal spacer is a water-based gel that is inserted into the space between the prostate and rectum, which is the lower part of your bowel. The spacer moves the rectum away from the prostate and helps to reduce radiotherapy side effects to the rectum.
What is transperineal placement of biodegradable material?
Background. SpaceOAR is a biodegradable polyethylene glycol hydrogel that is injected as a liquid between the prostate and rectum under ultrasound guidance. Once injected, the liquid solidifies within seconds into a hydrogel that pushes the anterior rectal wall away from the prostate.
Is SpaceOAR an implant?
SpaceOAR Hydrogel is an FDA-cleared implant made of two liquids that when combined, form a soft gel-like synthetic material.
What are the side effects of SpaceOAR?
Potential complications associated with Space OAR hydrogel include but are not limited to:
- Pain associated with Space OAR hydrogel injection.
- Local inflammatory reactions and infections.
- Injection of air, fluid or Space OAR hydrogel intravascularly.
- Rectal mucosal damage, ulcers, bleeding, constipation and rectal urgency.
How is a space oar put in?
SpaceOAR Hydrogel is injected as a liquid through a needle inserted between the rectum and the prostate. It can be implanted via a local anesthetic that will numb the injection area or under general anesthesia that will put a patient to sleep during the procedure.
What is transperineal placement?
In transperineal biopsy, the urologist passes the biopsy needle through the perineal skin and into the prostate, rather than passing the biopsy needle through a potentially contaminated rectum. The biopsy needle is still guided by an ultrasound placed in the rectum.
How are fiducial markers placed in the prostate?
Fiducial markers are placed using a needle that is inserted into the area of the lesion with the help of computed tomography (CT) or ultrasound (US). Markers pre-filled in the needle are then advanced to carefully plotted positions in and around the tumor.
