  Purpose

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.


Condition Intervention
Kidney Stones
 Other: CT Scan followed by ultrasound

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of Twinkling Artifact Compared to Computed Tomography for Evaluation of Kidney Stones

Further study details as provided by Ottawa Hospital Research Institute:

Primary Outcome Measures:
  • The detection of kidney stones on ultrasound compared to CT. [ Time Frame: One year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Presence of hydronephrosis, a sign of obstruction of the urinary tract, will also be detected. [ Time Frame: one year ] [ Designated as safety issue: No ]

Enrollment: 52
Study Start Date: September 2009
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
