Human Cadaver prostate tumors and canine prostate glands in vivo were irradiated by Nd:YAG laser with different power levels and pulse durations. Temperature measurements were carried out by an arrangement of micro thermo couple, digital volt meter and computer in different layers of the prostate and the rectum. The temporal and spatial temperature measurements showed a good correlation with the histological findings. Endoscopic laser irradiation of prostatic carcinoma in man was performed after TUR. There was a large penetration depth resulting a deep necrosis, but no perforation and no changes in the rectum were to be found also after high power laser irradiation.
