The therapeutic application of hyperthermia in the bladder.

Experience with 10 cases of hyperthermic irrigation of the bladder suggests that irrigation with saline at 80 degrees C for 10 to 15 min will stop bleeding and destroy epithelium and muscle layers without causing visceral injury or systemic disturbance. It may be preferable to cystectomy in certain poor-risk patients, or in those who refuse cystectomy for fear of impotence.
