We examined the distribution of interstitial temperature in the canine prostate during balloon laserthermia. The laser equipment (CL50FS, SLT Japan Co. Ltd) generated Nd: YAG laser (1,064nm) and the laser was irradiated over 360°cylindrically by laser balloon (2cm long) with circulation system of cooling water. By measuring the temperature at 3-5 minutes after the beginning of the treatment, we obtained following results. The temperature of the bladder neck and urethral sphincter maintained below 41°C except extreme conditions. The effect of cooling of the tissue is within 6mm and direct transmission of laser energy is within 10mm.
