Study to Look for Artifact on Computed Tomography (CT) Representing 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.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Evaluation of Twinkling Artifact Compared to Computed Tomography for Evaluation of Kidney Stones|
- The detection of kidney stones on ultrasound compared to CT. [ Time Frame: One year ] [ Designated as safety issue: No ]
- Presence of hydronephrosis, a sign of obstruction of the urinary tract, will also be detected. [ Time Frame: one year ] [ Designated as safety issue: No ]
|Study Start Date:||September 2009|
|Study Completion Date:||September 2010|
|Primary Completion Date:||September 2010 (Final data collection date for primary outcome measure)|
suspect kidney stones
Patients presenting with flank abdominal pain
Other: CT Scan followed by ultrasound
A limited U/S is performed after the CT scan which is ordered by the Emergency Department physician.
All patients aged 18 years of age and over who are undergoing a renal stone protocol for evaluation of flank pain will be included.
Pregnant patients will not be included.
