Kidney stones: For most cases of kidney stones, you will be told to drink plenty of water and other fluids and to take pain relievers.
Most stones will pass through urinary system by themselves. In certain instances, more extensive measures may be required.
One form of therapy, called extracorporeal shock wave lithotripsy, uses sound waves to crush the stones. The smaller pieces can then pass through more easily, though some pain will remain.
Another form of therapy uses cystoscopy to find the stone in the ureter and then to grab and remove it with a small scoop.
