At Cook Children's our goal is to constantly improve the care we deliver to our patients. To keep that commitment we provide the absolute latest technology and treatments available. Today that means making complicated surgeries simpler, so kids can get better, heal faster, and be home quicker.
Performed by our renowned urology robotic surgical team, the surgery itself looks like a cross between the latest in futuristic robot technology and the coolest video game you could ever play. The surgeon sits in a chair and looks into a screen that looks similar to what people wear to play a virtual reality game. Using the video screen and a gloved device the surgeon directs the robot arm to deliver the most precise and meticulous operation possible.
Along with the precision of the surgery itself, the minimally invasive procedure reduces much of the pain and many complications associated with open procedures surgeons usually perform. This means safer surgeries, with much faster recovery times for the kids we see.
An amazing advancement for surgery, the da Vinci Xi robotic technology allows us to provide minimally invasive surgery on any number of procedures, ranging from the most routine to the most complex cases.
Of course, no surgery seems routine when it is your child. But because the surgery is minimally invasive, we are able to return your children home more quickly than most parents ever thought possible—sometimes as early as the same day or the next day. At Cook Children's, our goal is to return your child back to being a kid as quickly as possible.
