Transurethral microwave thermotherapy for prostatism: early Mayo Foundation experience

As part of a multicenter investigative trial, transurethral microwave thermotherapy of the prostate was used in 60 men with symptomatic benign prostatic hypertrophy. A single office treatment on the Prostatron, a device that provides concurrent microwave heating of the prostate and conductive cooling of the urethra, was well tolerated and caused no major adverse events. Symptomatic improvement, especially the decrease in nocturia and urgency, was dramatic, and urinary flow was improved at 6 weeks. Continued follow-up suggests that further improvement will be achieved and that transurethral microwave thermotherapy has a role in the treatment of benign prostatic hypertrophy.
