Abstract
One of the new treatment regimes available for symptomatic benign prostatic hyperplasia (BPH) involves heating the prostate. This rapidly evolving technique aims to provide relief to obstructed patients in an outpatient setting with minimal anesthesia. The term “hyperthermia” has become associated with the current trend for heat treatment of the prostate, but it has its origin in the treatment of malignant tissue. Indeed, the initial experience with transrectal microwave probes was gained in treating prostatic cancer. An applicator containing a microwave antenna was developed which could be placed into the rectum and aimed at the prostate. This energy delivery system allowed controlled heating of the prostate to specific temperatures within a confined space. The treatments for prostatic cancer were based on the observation that malignant tissue, but not normal tissue, was susceptible to temperatures of 42°–43.5°C. This temperature range has been adopted by some of the current devices to treat BPH, and the use of the term “hyperthermia” is thus restricted to define those treatments which developed directly from cancer therapy and which heat to <44°C. Hyperthermia treatments for BPH are delivered by microwave antennae placed in the rectum and do not cause tissue necrosis.
