Advances in laser technology in urology.

Since the Ruby laser was first developed in 1960 as the first successful optical laser, laser energy has continued to be developed and used in industry and medicine alike. Laser use in urology has been limited, however, largely until the last decade. The unique properties of laser energy have now led to its widespread use within urology, particularly in the treatment of benign prostatic hyperplasia, urolithiasis, stricture disease, and novel laparoscopic applications. This article details laser developments in each of these areas.
