If i had a ct scan without contrast would kidney stones show up ...

Yes: In fact, ct scanning without contrast is becoming the gold standard evaluation for kidney stones. Contrast material frequently obscures stones and makes their identification difficult. Stones as small as 1 mm can be detected with unenhanced ct technique. Radiolucent stones which cannot be seen well with plain x-ray technique do show up well with unenhanced ct scan.
