Rectal Spacer for Prostate Radiation

Protecting the Rectum During Prostate Cancer Treatment

A rectal spacer is a temporary, gel-like material placed between the prostate and rectum before radiation therapy. By creating additional space between these organs, a spacer can help reduce the amount of radiation delivered to the rectum. We work closely with your Radiation Oncologist to optimize your preparation for treatment, minimizing potential side effects, and bringing you back to full recovery as quickly as possible!!

How Does a Rectal Spacer Work?

• Creates separation: The spacer gently increases the distance between the prostate and rectum.

• Helps protect healthy tissue: The additional space can reduce radiation exposure to the rectum.

• Reduced side effects: Lower rectal radiation exposure may help decrease certain bowel-related side effects.

• Temporary by design: The spacer is gradually absorbed by the body after treatment.

What to Expect

Rectal spacer placement is performed as an outpatient procedure with local anesthesia and sedation. Using image guidance, the spacer is placed through the perineum—the area between the scrotum and anus.

Our care team will provide specific instructions regarding preparation, the procedure, and recovery.

Is a Rectal Spacer Right for You?

A rectal spacer may be appropriate for some men receiving radiation therapy for localized prostate cancer. Your radiation oncology team will evaluate your individual anatomy, cancer characteristics, and treatment plan to determine whether a spacer is recommended.

Our Goal

Deliver effective prostate cancer treatment while helping protect surrounding healthy tissue.
