Otherwise a noncontrast helical CT scan with 5 millimeters (0.2 in) sections is the diagnostic method to use to detect kidney stones and confirm the diagnosis of kidney stone disease. [16] [57] [61] [66] [7] Near all stones are detectable on CT scans with the exception of those composed of certain drug residues in the urine, [59] such as from ...
Even though US has a lower sensitivity and specificity than CT for the detection of kidney stones (urolithiasis), US, if available, is recommended as the initial imaging modality in patients with renal colic and suspected urolithiasis. US has no risk of radiation, is reproducible and inexpensive, and the outcome is not significantly different ...

A kidney stone is a hard object, which can be as small as a grain of salt or as big as a golf ball, made from chemicals—calcium oxalate, uric acid, struvite, and cystine—found in our urine ...
Ultrasound imaging is useful for detecting stones, for example kidney stones or gallstones, because they create a clearly visible ultrasound shadow behind the stone. [ citation needed ] Ultrasonography can be used to guide procedures such as treatment for kidney stones with extracorporeal shock wave lithotripsy , needle biopsies or paracentesis ...
Kidney stones are caused by high levels of the minerals calcium, oxalate, and phosphorus in urine. These minerals are normally found in urine and do not cause problems at low levels. However ...
