Measurement of thermal effects on the optical properties of prostate tissue at wavelengths of 1,064 and 633 nm

The extent of thermal injury during laser prostatectomy is dependent on the light distribution in laser‐irradiated tissue. As tissue is irradiated, the optical properties change as a function of temperature due to an alteration of molecular and cellular structure. The purpose of the present study was to determine how the exposure of both fresh and previously frozen canine prostate tissue to elevated temperatures affects the optical properties.
