Cryosurgery for Renal (Kidney) and Prostate Cancers

Cryosurgery is the use of extreme cold to destroy abnormal or diseased tissue. It is another minimally invasive technique that we offer to patients with kidney and prostate cancers that allows urologists to target very small areas with little blood loss and fewer complications. 

It is a minimally invasive treatment option for patients with kidney and prostate cancers in which urologists and interventional radiologists work together. Cryosurgery enables the treatment team to target very small areas with little blood loss and fewer complications. Additionally, if there is cancer relapse, cryoablation can be performed multiple times. 

  • Cryoablation of a renal tumor is a minimally invasive procedure performed by placing metal tubes in the kidney through the abdominal wall and running a special gas through the tubes, which creates an ice ball. The ice ball causes cellular breakdown – like frostbite – and kills the cancer. Cryoablation is best suited for tumors no larger than 3.5 cm in diameter. 

  • Cryoablation of the prostate does not require a hospital stay and there is little to no blood loss. Real-time ultrasound images enable the physician to sculpt the ice to the precise shape of the patient’s prostate, leaving nearby healthy tissue intact and preserving urinary continence in nearly all cases.
