Cryoablation (also called cryotherapy or cryosurgery) is a process that freezes cancerous cells in the prostate and cuts off their blood supply. The procedure involves cycles (usually two) of freezing and thawing of the prostate with cooling and warming agents passed through tiny probes into the prostate. Each cryoprobe is a small needle that forms an “ice ball” around the probe, which immediately destroys all of the tissue within the ice (including the cancer).
(But don’t worry about those ice balls. Fortunately, the ice stays local within the prostate and does not affect the family jewels!)
After treatment, your immune system clears out the frozen cells and leaves scar tissue behind.
Cryoablation is less invasive than other prostate procedures, but full-prostate ablation has a high risk of erectile dysfunction. In some cases, Dr. B-T will recommend a focal (partial) ablation. Focal ablation treats only the tumor cells and leaves the rest of the prostate tissue intact. Think of the needle probes as little snipers taking aim at the cancerous cells on your prostate.
When focal cryoablation is possible, you are more likely to retain your sexual and urinary function.
