Cryosurgery for kidney cancer is performed either through
an open surgical procedure or by use of a laparoscope. Using
ultrasound, the surgeon places cryoprobe(s) in the center
of the lesion. The probe is then cooled, forming an ice ball
of the lesion, which results in the death of the cancerous
The advantages of cryosurgery for the kidney include minimal
blood loss, shortened hospital stay, preservation of kidney
function, minimal pain and less expense than traditional approaches.
