Preparing for Electrothermal Catheter Therapy

Electrothermal therapy, also known as intradiscal electrothermal therapy, is often done in a hospital or surgery center. You will not need to stay overnight. Before the procedure, you and your healthcare provider will discuss how you need to prepare.

Your exam and tests

You’ll have an exam to make sure you are healthy enough to have this procedure. You will also have tests that give information about your disk. These include:

  • A discogram, which pinpoints the disk that is causing your pain.

  • Imaging tests, such as an MRI or a CT, which may help your healthcare provider learn more about how your disk is damaged.

Before the procedure

Do's and don'ts:

  • Tell your healthcare provider about all the medicines you take. This includes over-the-counter medicines, herbs, vitamins, and supplements.

  • Stop taking medicines as advised by your healthcare provider.

  • Stop eating and drinking 8 hours before the procedure.

  • Arrange for an adult friend or family member to drive you home.

  • Allow time to check in. You will need to sign a form stating that the procedure has been explained to you.

Preparing at home

Arranging a few things ahead of time can make recovery easier and safer.

  • Store supplies between hip and shoulder level. That way you can get to them without reaching or bending.

  • Arrange for rides. You may not be able to drive for a week or more after the procedure.

  • Find someone to help with chores and errands.

  • Get a pair of slip-on shoes with closed backs. That way you won’t have to bend to put on your shoes.
