The cryoneedle
is the tool used to grow iceballs on the prostate gland
for the newer and more effective prostate cancer cryotherapy.
Cryoneedles are ultra-thin 17-guage needles that are
1.47 millimeters thick. The third-generation cryotherapy
needles circulate argon and helium gas according to
the Joule-Thomson principle for the freezing and facilitated
thawing of the prostate gland. Prostate cancer is a
tumor that grows on the prostate gland. During cryotherapy,
up to 25 needles are inserted percutaneously through
the perineum. The thinness of the needles allows to
for enhanced maneuverability and increased precision.
Prostate cancer cryotherapy is an effective tool for
treatment, especially salvage therapy after radiation
therapy has failed. Rather than using higher doses of
radiation on tissue that is most likely radioresistant,
cryotherapy uses a different element to treat prostate
cancer.
