[Noninvasive, local microwave hyperthermia for deep-seated tumors: III. Benign prostatic hyperplasia]

Poor operative risk patients with benign prostatic hyperplasia were treated as outpatients with local hyperthermia without sedation, for 1 hour, twice weekly. As a result of the treatment it was possible in 61% to remove indwelling catheters and voiding was resumed for up to 61 months after treatment. 70% of those without indwelling catheters improved clinically and remained so for 67 months after completion of treatment. There were no side-effects or sequellae of the treatment. Because of its safety, simplicity of application and good results, it is recommended as the treatment of choice for poor operative risks.
