There has been an explosion in minimally invasive surgery (MIS) in urology. As surgicalsubspecialists, urologistswereslowtoembraceminimallyinvasivesurgery at its inception. However, in the last decade, the interest in MIS has grown ex- nentiallyinurology.Laparoscopicrenalproceduresarecommonplace, andmoreand more complex oncologic and reconstructive procedures are performed laparosc- ically. Much of this exponential growth has been due to the rapid dissemination ofrobotictechnology, speci?callyforprostatectomy.Soonafterward, roboticte- nology was applied to other complex lower tract oncologic and reconstructive procedures.Roboticassistancehasalsobeenappliedtouppertracturologicpro- duressuchaspyeloplastybutitsapplicationforpartialnephrectomyismorerecent. It has become apparent that robotic technology can serve as an interface between openandlaparoscopicsurgeryforthelaparoscopicallynaivesurgeon.Ithascertainly been shown to be so for prostatectomy, and whether the same pans out for partial nephrectomyisyettobeseen. As more experience is gained in MIS, more and more complex procedures are performedlaparoscopicallyandrobotically.Contrarytologicalexpectation, thein- denceofcomplicationshasindeedincreasedwithincreasingexperienceinMIS.This ispurelyare?ectionofthecomplexityoftheproceduresperformedratherthans- gical ineptitude.
