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.

Onset of symptoms of urinary urgency, frequency, burning, voiding small volumes usually indicates the stone is at the UVJ (ureter meets bladder). The absence or disappearance of pain does not guarantee stone passage. ...Read more

Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients.
