Your first diagnosis of kidney stones often occurs when you see your doctor or go to an emergency room because you are in great pain. Your doctor or an emergency medicine specialist will ask you questions and examine you. After you pass a stone, your doctor may give you another exam to find out whether you are likely to get kidney stones again.
Tests to diagnose kidney stones
Your doctor may do one or more of the following tests to help diagnose kidney stones, see where they are located, and find out if they are causing or may cause damage to the urinary tract.
A noncontrast spiral computed tomography (CT) scan is the preferred test for kidney stones. It is a special type of CT scan that moves in a circle.
