Cryotherapy

Cryoablation is the process of freezing the abnormal cells or kidney tumors. This minimally invasive process typically only requires an outpatient stay in the hospital. It can also be referred to as Cryotherapy.

You’ll be taken into the CT scanning room and assisted onto a scanning table. Monitors for blood pressure, heart rhythm and rate, and oxygen level will be attached to you. At this time, you will be given light sedation.

Images are obtained and the area is identified and marked by the physicians. You will be given local numbing medication into the skin, and then cryotherapy needles will be placed into the abnormal tissue or mass.

A biopsy of the abnormal tissue or mass will be taken if appropriate. The amount of needles needed to perform the cryotherapy depends on the size of the abnormal tissue or mass.

The needles are placed in the abnormal tissue or mass and the freezing begins; two sessions of freezing are completed to ensure an adequate treatment.

After the procedure, you’ll be monitored for any side effects that include pain, nausea or vomiting, or bleeding from the procedure site. You’ll be on bedrest for about four hours and may get up with assistance to use the restroom if the nursing staff determines you’re stable.

If you are recovering well from the procedure, you may be allowed to go home the same day. Occasionally, patients need to stay overnight for observation.
