This article is intended to act as an introduction to a session on high technology and the prostate. The session includes microwaves, lasers, ultrasound, and cryotherapy and different authors describe these modalities in varied ways. However, there are already a number of approaches that can be used when treating an obstructive prostate gland. Nevertheless there is still a place for researching into new modalities for this condition. This is because the basic problem is a very simple one, the destruction of the obstructing portion of the prostate gland without damaging surrounding structures. Also prostatic surgery is very common and the revenue consequences are enormous. Approximately 400,000 transurethral prostatectomies are performed per year in the USA.
