You are scheduled for an Ablation procedure. Take the D elevators to the 3rd floor and go to First Day Surgery. Your procedure is scheduled on:
______________ at ___________.
We use microwave ablation to treat your liver, lung, bone, kidney, or other tumors. It is less invasive than standard surgery. Recovery time is faster. It is done by a radiologist. They use ultrasound and/or CT scan to guide the treatment.
Long thin needles are inserted through the skin into the tumor. Microwave ablation is a heat-based method. Microwave current is put through the needles into the tumor. The heat from the current destroys the tumor tissue. Most of the normal tissue around it is spared. Sterile water may be used to protect other body parts from being burned.
Problems after are rare but can include bleeding or infection. Other rare problems may include a collapsed lung, a bowel injury, kidney or liver failure.
Cryo-ablation is also used to treat kidney tumors. Long thin needles are inserted through the skin into the tumor. Extreme cold is sent through them to freeze the tumor. Sometimes sterile water is inserted for this treatment also. Your urology doctor will be working with the radiologist during this procedure. They will decide the best treatment for you.
Before the Procedure
You will have a planning ultrasound. We will schedule this visit for you.
Tell us if you have allergies to medicines, X-ray dye, crabs, or shellfish.
Tell us if you are taking medicines which thin your blood. You will be asked to stop taking them 5-7 days before the procedure. Do not stop these medicines without talking to the doctor who ordered them.
If you take aspirin, you will stay on your 81mg dose or decrease your 325mg dose to 81mg if you have any cardiac or vascular stents. The nurse will discuss this with you.
You will take most of your prescription medicines as usual the morning of the procedure. If there are some you should not take, you will be told by your doctor or by the nurse that calls you before you come in.
Let us know if you have trouble with any joints, mainly your hips, shoulders, or neck. Tell us if you have had any neck or back surgeries, or any devices like an insulin pump or pain stimulator.
