Advantages of CT scanning include the following:

  • It can reveal other pathology (eg, AAAs, appendicitis, pancreatitis, cholecystis, ovarian disorders, diverticular disease, renal carcinoma). [33] If the patient’s true underlying pathology is something other than a kidney stone, the CT scan is more clinically useful than an IVP for examining the possibilities.

  • It can be performed quickly (< 5 min acquisition time)

  • It avoids the use of IV contrast materials.

  • The density of the stone can assist in predicting stone composition and response to shockwave lithotripsy.
