Shortly after their development, lasers were referred to as a solution eagerly looking for a problem. Nevertheless, lasers progressed rapidly as an omnipresent part of modern technology and procedural medicine. Advances in lasers and fiberoptics have made them ideally suited to travel through routes in the human body where no hand or scalpel has gone before. With its widespread use of small-diameter endoscopic instruments, urology has been drastically and positively influenced by this technology, perhaps more so than any other medical subspecialty.
