Study to Look for Artifact on Computed Tomography (CT) Representing Kidney Stones

June 27, 2011 updated by: Ottawa Hospital Research Institute

Evaluation of Twinkling Artifact Compared to Computed Tomography for Evaluation of Kidney Stones

Patients suspected of having a kidney stone are usually evaluated by computed tomography (CT) scan. The investigators hypothesize that ultrasound (U/S) should be sufficient to evaluate kidneys for suspected renal stones.
