Design outcomes

Primary

Measure	Time frame	Description
hydronephrosis bedside ultrasound	Sept 2011-Jan 2013	To determine the overall sensitivity and specificity of hydronephrosis on point-of-care bedside ultrasound to identify hydronephrosis as compared to hydronephrosis found on by CT.

Secondary

Measure	Time frame	Description
hydronephrosis bedside ultrasound	Sept 2011-Jan 2013	To determine test performance characteristics of hydronephrosis on point of care ultrasound with the goal of incorporating POC US into a prospective rule for determining which patients with suspected renal colic require CT evaluation.

Other

Measure	Time frame	Description
hydronephrosis	Sept 2011-Jan 2013	To prospectively correlate the finding and degree of hydronephrosis on point of care ultrasound with stone size (a marker for likely spontaneous passage).
