What is the definition or description of: ultrasound of kidneys shows stone?

Usually definitive.: Ultrasound shows the renal outlines, partly because they are surrounded by fat. Calcific densities are shown by us as highly reflective abnormalities, and there is not much question. The presence of calcific densities in the kidneys makes the diagnosis of stone very likely. If it has been there for years, it may not be important, but otherwise, have it checked.

Stones are opaque: On ultrasound the most common types of kidney stones (calcium oxalate) appear white and as such are easily seen. Note there are other types (uric acid) that will not be identified in most cases by ultrasound. Also keep in mind a stone can be seen and if imbedded in the tissues may never be passed. Ultimately stone location is helpful when considering if it will ever be a problem.

Sono-opaque & shadow: Kidney stones on ultrasound appear like distict, discrete white areas which cast a sonographic shadow. Involve no radiation and thus preferred or mandatory in pregnancy & better fior kids. Is relatively inexpensive compared to other radiologic studies and can demonstrate non-radioopayue calclui. Inferior to helical ct scans.
