Paper Abstract

Many novel treatments for BPH are predicated on depositing power, for example using a laser, microwave, or rf source, to generate heat. In order to be useful and effective a requisite amount of power must be deposited in the tissue so that a reasonable amount of tissue can be necrosed in a reasonable time. The potential to be effective is fundamentally effected by the electromagnetic frequency. The frequency of the power source dictates the penetration characteristic in tissue, and thus the size of the heat source that can subsequently conduct further into the tissue. Because tissue char limits the peak temperature accessible for any power source, a particular frequency can only effectively heat a certain amount of tissue, given similar conditions. Too large a penetration of power can be as ineffective as too shallow.
