What is Cryoablation?

Cryoablation is a minimally invasive cancer treatment that uses extreme cold to destroy tumors. During the procedure, an interventional radiologist inserts a thin probe (cryoprobe) through the skin into the tumor using CT or ultrasound guidance. Argon gas circulates through the probe, creating an “ice ball” that freezes and kills cancer cells while sparing surrounding healthy tissue. This technique, once limited to operating rooms, is now performed through a small incision without major surgery, making it an effective option for patients who cannot undergo traditional operations.

What are the Benefits of Cryoablation?

Cryoablation offers several advantages: it preserves most healthy kidney tissue, has a low complication rate, and can be repeated if needed. Most patients go home the same day or within 24 hours. The most common side effect is a temporary bruise near the kidney. For advanced or metastatic renal cell carcinoma, cryoablation can help control tumor growth and relieve symptoms, even though it is not considered curative.
