A 34-year-old member asked:

How well do kidney stones show in a ct scan without contrast?

Very Well: Almost all kidney stones show up extremely well on a non-contrasted ct scan. A stone that was composed entirely of protein matrix may not show but the typical calcium oxalate, calcium phosphate, and uric acid stones show up very well.

yes!: Yes- that is exactly how a ct for renal stones should be performed- with oral or IV contrast.

Yes, but: Kidney stones that do not contain calcium may not show up very well on a ct. However, these would need to be very small, so whether they are clinically signifcant is questionable. If the ct says no stone, the chances are good that either there is no stone, or it is too small to be worrisome.

Not always: This does depend on the size of the kidney stone and the way the study is performed. Suffice it to say almost always

What happens if you have kidney stones and do a lot CT scanes?

Hopefully nothing: There is a risk of developing cancer as a direct effect of radiation from a ct scan. The chances of this happening increase as the cumulative radiation from the scans increases.
