2. 52000 new cases per year in the USA
Kidney Cancer
52000 new cases per year in the USA
75% are incidentally discovered when patients are examined for other reasons.
Because of utilization of Cat scans, Ultrasounds and MRIs by Radiologists
This Incidental detection results in improved long term survival/cure rate because many caught early- now70% (40% in 1960’s)

3. Kidney Cancer in the US
52000

4. Percutaneous ablation
Treatment options
Removal of whole kidney
Removal of tumor and surrounding part of kidney
Open surgery vs laparoscopic surgery or ablation
Percutaneous ablation

5. Percutaneous Cryoablation
A thin, needle-like, probe is directed from the skin into the tumor
NO INCISION or SURGERY
Under direct visualization using a CAT scan or Ultrasound
The probe freezes the tumor to lethal sub-zero temperatures
Probe is thawed and removed
Under minimal sedation
NO GENERAL ANESTHESIA

11. Minimally-Invasive Cryoablation for Kidney Cancer
Cryoablation can be a curative treatment option for patients with kidney cancer
4 cm or less-success rate is 97%
* Even patients with larger tumors can benefit from this procedure especially those who cannot have general anesthesia or surgery
* Half of patients go home same day,
the rest after one night’s stay
