Objective: To examine the role of microwave power and blood flow on temperature variations and tissue destruction in the prostate, using a theoretical model of transurethral microwave thermotherapy (TUMT), and thus compare fixed-energy TUMT with no intraprostatic temperature monitoring (constant microwave power applied over a fixed period) with 'feedback' TUMT in which the microwave power is adjusted according to the monitored intraprostatic temperature.
Materials And Methods: The temperature distribution in the prostate was modelled for a typical TUMT catheter at various blood flow rates. The volume of tissue destroyed was simultaneously calculated from cell survival data after thermal exposure. Read More

The underlying principle behind new minimal invasive procedures, such as microwave thermotherapy, is to coagulate the prostatic adenomatous tissue by means of heat. This article describes the action of heat on tissue and identifies areas of concern during treatment. The extent of the necrosis during treatment is governed by two physical variables: the intraprostatic temperature and the duration of the heat exposure. Read More

Purpose Of Review: From all the available thermoablative methods for the treatment of symptomatic benign prostatic hyperplasia, transurethral microwave thermotherapy is considered as standard in minimally invasive management. The literature is enriched by several new studies on transurethral microwave thermotherapy, and thus this review presents up-to-date information about thermotherapy.
Recent Findings: New studies have provided significant information regarding differences in outcome for devices with different protocols and selection criteria, confirming the superiority of high-energy programmes. Read More
