Official title
Kidney Stone Structural Analysis by Helical Computed Tomography (A Pilot Study)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
