A thermocouple
is a device used in cryotherapy for the treatment of
prostate cancer. The thermocouple is made up of two
different metals and accurately measures the change
in temperature. In cryotherapy, usually at least two
thermocouples are used to ensure that the prostate gland’s
temperature is lowered to negative 40 degrees Celsius
or lower. Cryotherapy is a relatively new treatment
for prostate cancer. Cryotherapy works by damaging the
cells through ice crystal formation and changes in pH
levels. This form of prostate cancer is also effective
as a salvage treatment when radiation therapy has failed.
Failure of radiation therapy usually indicates that
prostate cancer has developed radioresistance. Cryotherapy
therefore is an effective alternative during salvage
therapy.
