April 3, 2007 - Mayo Clinic researchers recently reported that freezing kidney tumors through percutaneous cryoablation may be able to help those who are not candidates for surgical treatment.
The percutaneous ablation process uses needles to penetrate the skin and delivers either high-intensity, tissue destroying heat through radiofrequency ablation, or freezing cold temperatures through cryoablation, directly to the tumor. The procedure shortens the hospital stay and reduces recovery time.
