You might need to have a surgical procedure called shock wave lithotripsy that uses sound waves to break the stone up into smaller pieces, making it easier to pass. Surgeons can also use a special camera called ureteroscope (a narrow tube with a camera at the end) to get to the stone in the ureter or kidney and break it up using laser.
