Greensboro, NC -- UNC Tar Heels coach Roy Williams underwent surgery Wednesday to remove a tumor on his right kidney. Of course, we wanted to learn more about the hall of fame coach's procedure and what the road ahead may hold for Coach Williams.

Dr. Daniel Woodruff, with Alliance Urology in Greensboro, said, "We use is a robotic device. It's still an instrument as much as anything else that the surgeon still controls, but it allows magnified viewing, allows surgery in a very small space, and allows more free movements and more precise movements with our instruments."

Woodruff performs the same kind of surgery UNC doctors performed on Coach Williams. Woodruff says doctors typically don't take any risks when it comes to kidney tumors. He said its one of the few organs on the body they won't perform a biopsy. More often than not, they'll perform surgery to take it out, before things get worse. He said, "Once a tumor's in the kidney, if its confined to the kidney you have about a 95% survival rate. Once its outside of the kidney, the survival rate drops dramatically because kidney cancer is not killed by radiation, its not killed by chemotherapy."
