Picture of Kidney Stone Diagnosis
The diagnosis of kidney stones is suspected by the typical pattern of symptoms when other possible causes of the abdominal or flank pain are excluded. Imaging tests are usually done to confirm the diagnosis. A helical CT scan without contrast material is the most common test to detect stones or obstruction within the urinary tract. In pregnant women or those who should avoid radiation exposure, an ultrasound examination may be done to help establish the diagnosis.
