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 40°C to 45°C. 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.
