Laparoendoscopic single site surgery in urology.

Laparoendoscopic single site (LESS) surgery is a recently coined term that refers to a group of techniques that perform laparoscopic intervention through a single abdominal incision often hidden within the umbilicus. The relative ease and swiftness of early success of LESS surgery is in large part because of the familiarity of current practitioners with advanced laparoscopic techniques and the advent of several technologic advances in the areas of instrumentation, camera systems, and access devices. As ongoing advancements in instrumentation and future robotics platforms are incorporated, the scope and application of LESS surgery is likely to expand. Ultimately, prospective studies that compare the safety and effectiveness of this new approach with the standard conventional laparoscopic approach will determine the future role in surgical practice.
