If you need surgery anytime soon, there is an increasing likeli-hood your surgeon will be assisted by a robot. For many urological procedures, such as prostatectomies for prostate cancer, robot-assisted surgery is now the standard-of-care, said Benjamin Chung, a urologist and director of robot surgery at Stanford University in Palo Alto, Califia. Chung estimates that as many as 90％ of prostatectomies in the United States are performed with robotic assistance [1]; this fraction surpasses 60％ for partial nephrec-tomies, and 27％ for radical nephrectomies [2,3]. Over the last 20 years, it has progressively become more and more common,said urologist Andrew Hung, director of robotic simulation and education at the University of South Califia in Los Angeles.
