Kidney stones are made up of crystals (including calcium and phosphate) that develop in the urine in the urinary tract. Men are more likely than women to get them, and Caucasians get them more often than blacks. Most kidney stones pass out of the system without surgery (a common treatment is to drink several quarts of water a day and take pain medication as needed). But if you think you may have kidney stones, see your doctor. If not treated and the stone gets stuck, it can cause an infection and, rarely, kidney damage.
