Patient Instructions

  • Ultrasound Guided Hydrogel Placement

Ultrasound Guided Hydrogel Placement

Ultrasound Guided Hydrogel Placement is used to put a temporary spacer between the prostate and the rectum prior to receiving radiation therapy to the prostate. The Hydrogel helps protect the rectum during radiation treatments to the prostate. The Hydrogel will naturally absorb in about six months.

Before your Procedure

  • Certain medications may increase your risk of bleeding and you may need to stop taking these medications before your procedure.
  • No solid foods 8 hours prior to procedure and no fluids 4 hours prior, unless otherwise directed by your provider.
  • Check into Outpatient Services 1 hour prior to your procedure time.
  • You will receive an I.V. antibiotic in Outpatient Services prior to your procedure. 

During your Procedure

  • You will be in a gown on a patient cart for this procedure.
  • Your procedure will be done in ultrasound with the radiologist. You will receive sedation after talking to the radiologist and making sure all your questions are answered.
  • An ultrasound transducer will be inserted into your rectum, so the radiologist can visualize the correct area for the placement of the Hydrogel. A small needle will be used to inject the Hydrogel between the prostate and rectum.
  • You will receive a local anesthetic (numbing medication) before the procedure. You may feel a burning sensation during this time.
  • The procedure will last approximately 30-45 minutes.

After the Procedure/Discharge Instructions

  • You’ve been given a sedative medication during your procedure. Because of the effects of the sedation, we recommend that you have someone stay with you the remainder of the day and overnight following your procedure.
  • Please DO NOT drive a car or operate machinery for the remainder of the day. Your reflexes and coordination are not normal.
  • Postpone signing any important papers or making any important decisions for 24 hours.
  • Do not take any muscle relaxants, sedatives, hypnotics or mood-altering medication today unless ordered by your physician who is aware of this medication today.

Activity

  • You can resume your normal activities with exception of driving or operating machinery, and avoid direct pressure to the procedural site. For example, do not ride a stationary bike.
  • Always be sure to check with your doctor for any restrictions associated with the procedure and your radiation treatment.

Symptom Control

  • Do not be alarmed if you have a small amount of blood from your rectal area.
  • You many experience some temporary discomfort at the injection site. Patients typically report no prolonged discomfort from the implanted Hydrogel. You may take a non-aspirin pain reliever (Tylenol) if not contraindicated.
  • If you take blood thinning medications, you may take them tomorrow.

When to call your doctor

Call if you experience any of the following problems:

  • Excessive or prolonged bleeding from the rectal area.
  • Severe pain or discomfort uncontrolled by Tylenol.
  • Fever greater than 100 degrees. It is not normal to have an elevated temperature following this procedure.
