How are kidney stones diagnosed?

Several different tests can verify the existence of a kidney stone. A physical examination may reveal colicky pain (in the groin) and pain in the lower back by the kidneys - often warning signs of the condition. An analysis of the urine will indicate whether or not there is blood in the urine and if there is a subsequent infection. Blood tests can be done to identify complications that may accompany a kidney stone and check the validity of the diagnosis. 

A CT scan of the abdomen is the most thorough way to test for kidney stones. A CT scan will ascertain the state of the ureter, bladder, and kidneys, whether or not a stone exists, the kidney stone's exact size and location, whether or not a blockage exists, and the state of the other adjacent organs such as the appendix, aorta, and pancreas. Pregnant women may receive an ultrasound rather than a CT scan in order to avoid unnecessary radiation. 

Once a patient is diagnosed with a kidney stone, simple x-rays will be used to track the stone's progress through the excretory system.
