This is just a urologic case. This actually is kind of a show-off case for me because this is a stone that we normally would not recommend shock wave lithotripsy. That stone is too big for shock wave lithotripsy, but this young lady happened to be a beauty pageant contestant, refused to have any incision on her body whatsoever, even the 1-inch incision it would take to do a percutaneous nephrolithotomy. She said, you need to do this without having any scars. So, I said, okay, it's probably going to take 4 or 5 treatments to do this, and we were just lucky enough that this stone was so soft that this was her result after one treatment: stone gone, normal kidney. So it really does work, and it works well.
