[Single-port in urology].
Single-port transumbilical laparoscopy has emerged as an attempt to further enhance cosmetic benefits and reduce morbidity of minimally invasive surgery. Within a short span, several clinical reports have emerged in the urologic literature. As this field is poised to move forward, a complete understanding of its evolution and current status seems imperative. We have summarized and reviewed the history of Single-Port across surgical disciplines. This review emphasizes nomenclature, surgical technique, instrumentation, and perioperative outcomes.


METHODS
Using the National Library of Medicine database, the English language literature was reviewed for the past 40 years. Keyword searches included scarless, scar free, single-port/trocar/incision, laparoendoscopic single site surgery intraumbilical, and transumbilical. Within the bibliography of selected references, additional sources were retrieved.


RESULTS
The major findings and surgical techniques described in these papers, are summarized in a chronological and subject-grouped manner.


CONCLUSIONS
Single-port has made its initial forays into laparoscopic surgery. Ongoing refinement in technique and instrumentation is likely to expand its future role.
