Renal cryoablation is a minimally invasive treatment used to destroy small kidney tumours by freezing them. It is most commonly used for early-stage kidney cancers or kidney masses that would otherwise require partial removal of the kidney.

Using advanced imaging guidance, small needles are guided into the tumour and extreme cold is applied directly to the tumour, causing the abnormal cells to die while preserving as much healthy kidney tissue as possible.

At SAVI, renal cryoablation is performed by subspecialty-trained interventional radiologists with expertise in image-guided cancer treatments. We work closely with urology, oncology, and your referring physician to determine whether cryoablation is the best option for your specific kidney tumour.

When Is Renal Cryoablation Considered?

Renal cryoablation may be recommended when:

• A kidney tumour is small and localized
• Surgery is high risk due to other medical conditions
• Preserving kidney function is especially important
• A less invasive option is preferred over surgery
• The tumour is detected early and suitable for image-guided treatment

Not all kidney tumours require immediate treatment. In some cases, active surveillance may be appropriate, and this is carefully discussed with your care team.

How the Procedure Works

Renal cryoablation is performed using CT or ultrasound guidance. Through a small skin puncture, thin needles (called cryoprobes) are placed directly into the kidney tumour. Extremely cold temperatures are then applied to freeze and destroy the tumour cells while minimizing damage to surrounding tissue.

Key advantages include:

• No large incisions
• No need for general anesthesia
• Targeted treatment of the tumour
• Preservation of normal kidney tissue
• Less pain and faster recovery compared with surgery
