The purpose of this study is to evaluate the effectiveness of percutaneous cryoablation for freezing kidney cancers. Cryoablation works by creating freezing temperatures with a needle probe inserted through the skin. When this probe is inserted into a tumor, the freezing temperatures are used to try to kill the cancer.
Researchers want to learn how well cryoablation destroys renal cancers. They will follow patients every five to seven months after the procedure to assess the therapy’s effectiveness.
