What is a prostate tissue spacer?
A prostate tissue spacer is used in men with prostate cancer undergoing radiation therapy. A hydrogel is used as a rectal spacer, which means it creates a temporary space between the rectum and the prostate. The gel decreases the amount of radiation your rectum is exposed to. This helps decrease the risk for urinary, bowel, and sexual side effects from radiation therapy.
What else do I need to know about a prostate tissue spacer?
The hydrogel is a soft gel made of mostly water. The gel is injected into your body with a needle and stays in place for about 3 months. Your body will absorb the gel and get rid of it through your urine in about 6 months. The hydrogel can decrease common side effects of prostate radiation therapy, such as the following:
- Urinary leakage or urgency
- Chronic diarrhea
- Erectile dysfunction
- Rectal pain and bleeding
How is a prostate tissue spacer implanted?
The hydrogel is implanted in your provider's office or an outpatient facility. The procedure usually takes about 30 minutes.
- You will be given local anesthesia to numb the area. You may feel pressure or pushing but should not feel any pain. Your provider may insert an ultrasound wand into your rectum to help guide the needle.
- A needle will be inserted in your perineum to inject the hydrogel. The perineum is the area between your scrotum and rectum. An imaging test may be done to check placement of the gel. You should be able to return to your usual activities after the procedure.
When should I call my doctor?
- You have a fever.
- You have questions or concerns about your condition or care.
