RADIOFREQUENCY ABLATION & CRYOTHERAPY

Cryotherapy

Radiofrequency Ablation (RFA)


RFA works by transferring an electrical current between electrodes through naturally occurring ion channels in biologic tissues, essentially creating a simple electrical circuit comprised of the generator, cabling, and electrodes, with tissue acting as the resistive element. Current flows through tissue which demonstrates electrical impedance causing frictional agitation and subsequent heat generation. The goal of RFA is to raise the target tissue temperature to a lethal level greater than 55 degrees Celsius. The final result of RFA is coagulation necrosis with initial protein denaturation and vascular congestion.


Cryotherapy


The use of cryotherapy for therapeutic intervention dates back to the Egyptians in 2500 BC. There have been significant advances since the first use of cryotherapy to treat tumors, reported in 1851. [6] The initial use of cryotherapy in urology was for treating prostate cancer. [7] Currently, it is utilized to treat prostate cancer and kidney cancer.

Currently using the latest advances in prostate imaging and MR US fusion guided biopsy technology, we can use the information to guide treatment. This guided treatment we call focal therapy. We have the ability to tailor the treatment to help patients avoid the typical side effects of prostate cancer therapy which include erectile dysfunction and leakage of urine (see video of an MR US fusion guided ablation). This is done as an outpatient in the office or the operating room.

Kidney cancer focal ablation is performed using a CT scanner to guide the needle placements and focus the treatment just on the area of the kidney where the tumor is. It is an outpatient procedure performed in the interventional radiology suite.
