Your treatment for kidney stones will depend on the type and cause of your kidney stone. Most stones can be treated without surgery. If you drink a lot of water (2.5-3L/day) and stay physically active this is often enough to remove stones smaller than about 5mm from your body. Your doctor may then prescribe medicines to reduce the pain. He/She may ask you to catch the kidney stone by passing your urine through filter paper or a tea strainer. The stone can then be analyzed to find out what type it is to help guide your treatment. If you have a kidney stone that hasn't passed out of the body within 1-2 months, it's unlikely to pass without treatment. Infections are usually treated with antibiotics.
