It may be accompanied by hematuria.An ultrasound is an appropriate first test to diagnose a kidney stone, a helical non-contrast CT scan—either low dose or standard dose may also be considered.Chemical analysis of the stone is very helpful in determining further treatment.Individuals with multiple stones, very early age of onset of stones, or multiple risk factors should undergo further metabolic workup to determine appropriate treatment for stones.
