Kishimoto) Hyperthermic treatment was performed in 10 cases of bladder tumor. Without anesthesia, bladder irrigation was carried out with isotonic saline or 10% urigal solution warmed at 40C to 45C. After the treatment tumor regression occurred in all patients. In two cases, tumors showed total regression after 10 times of the treatment. In the remaining 8 patients, tumors regressed over 50% of its content in cystoscopic finding. Hyperthermic treatment seems to be a preferable method for the bladder tumor cases with cardiovascular complication. This preliminary report is to be followed by further clinical and experimental investigations.
