Answer

If urinary tract stones are still a strong consideration despite normal ultrasonographic findings, a noncontrast helical CT scan is indicated. This has been shown to be a very sensitive and specific modality for identifying renal stones. The scan may also identify low mineral bone density, based o attenuation measured in Hounsfield units at the L1 vertebral body. [35]
