Hydronephrosis on Ultrasound With CT Finding in Patients With Renal Colic

Correlation of Hydronephrosis on Point of Care Ultrasound With CT Finding in Patients With Expected Renal Colic

The purpose of this study is to determine the overall sensitivity and specificity of hydronephrosis on point-of-care bedside ultrasound to identify hydronephrosis as compared to hydronephrosis found by CT.

Inclusion Criteria:

• Emergency Department patients 18 yrs or older with suspected renal colic in whom the clinician intends to obtain a CT scan to diagnose kidney stone.
• Informed consent will be required prior to enrollment in the study.
