Actual (reported)Current practices of the diagnosis of urinary stones gives little information on the probable fragility of stones using shock wave lithotripsy (SWL), and many patients receive more SW's than is necessary to break up their stones. Indeed, some patients are treated with SWL when their stones cannot be fragmented using this technology. The investigators have ample evidence that computed tomography (CT) images of kidney stones can reveal significant internal structure in stones-structure that is likely to be useful in predicting stone fragility-but no one has explored the use of clinical helical CT for this purpose. Also, the investigators do not know the effect that the human body wall and kidney tissue will have on the resolution of kidney stone structure with helical CT.

Actual (reported)To determine whether available clinical helical CT is able to reveal internal structure of kidney stones
Post op day one
To determine if high resolution CT can differentiate between plaque and renal calculi.

patients who require a CT scan prior to kidney stone surgery for diagnostic purposes
Patients who require a CT scan for diagnostic purposes prior to kidney stone surgery will undergo a high definition helical CT rather than the standard CT scan. This high resolution scan will then be reviewed by the researchers to help determine the type of treatment needed for the kidney stone removal. The aim is to see if the higher resolution will show more of the stone "anatomy" which will help the surgeon determine if the stone will be amenable to shock wave lithotripsy or if another type of treatment would best serve the patient needs.
