An apparatus for thermal treatment of the prostate has a liquid cooled urethral catheter (2), within which a microwave emitter (4)is disposed for heating a region around the prostatic urethra and a rectal probe for sensing the temperature in rectum, the catheter and the probe each comprising at least one temperature sensor (12, 16). Each temperature sensor includes a glass fibre having at one end a luminiscent member. The temperature sensor comprised in the catheter is removably disposed at the outer surface of the catheter, said one end being positioned in the region to be treated by heat during the heat treatment of a patient. The luminiscent member is an aluminium-gallium-arsenide stack, which, when illuminated, emits light having a frequency, which is dependent on the temperature of said member. |
