The first method to be used in searching for stones in kidneys and urinary tract is ultrasonography. A large majority of the kidney and urinary tract stones can be identified by this method. Ultrasonographic examination can sometimes be insufficient for small stones, urinary tract stones and in case of high amount of gas in the abdomen. Another method which is used often in searching stones is direct x-ray radiography or medicated radiography (IVP). In this method small stones and non calcium (non opaque) stones can not be identified. The golden method for searching stones is thin slice spiral tomography. All stones in the kidneys and urinary tract can be identified by this method. The disadvantage of this method is its imited use due to x-ray exposure of the patient.,
