What to Expect
Prior to Procedure
The care team may meet with you to talk about:
- Anesthesia options
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
- Fasting before the procedure, such as avoiding food or drink after midnight the night before
- Whether you need a ride to and from the procedure
- Tests that will need to be done before the procedure
Anesthesia
Local anesthesia will be used—the area will be numbed.
If this is done as part of another surgery, you may have:
- General anesthesia—you will be asleep, or
- Spinal anesthesia—you will be numb from the belly down
Description of the Procedure
The exact steps will depend on where the tissue is located. A probe is applied to the area. Or the probe may be passed through a small tube to the area. Imaging such as a CT scan, ultrasound, or MRI scan will help guide the doctor to the area.
A small amount of electricity is passed through the tube. This heats and destroys the tissue. The probe may also be used to destroy other areas of tissue.
How Long Will It Take?
About 10 to 60 minutes
Will It Hurt?
Pain after the procedure depends on the location and amount of tissue. Medicine and home care help
Average Hospital Stay
Some may leave the hospital on the same day. Others will need to stay overnight so the doctor can check them.
Post-procedure Care
Most return to normal activities within a few days.
Call Your Doctor
Call your doctor if you are not getting better or you have:
- Signs of infection, such as fever and chills
- Redness, swelling, excess bleeding, or any discharge from the incision
- Pain that you cannot control with the medicines
- Cough, problems breathing, pounding heart, or chest pain
