Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Renal colic is a common (1300 visits per year at our institution) and painful condition caused by stones in the kidney and ureter, and can be mimicked by life threatening conditions such as a ruptured abdominal aortic aneurysm (AAA). This can create clinical uncertainty. Emergency department targeted ultrasound (EDTU) is performed by an emergency physician at the patient's bedside, and has been shown to be accurate, safe, and efficient. We have shown that EDTU can accurately identify hydronephrosis, which is a predictor of complications of kidney stones. A normal formal ultrasound (US) predicts an uncomplicated clinical course. We will assess the accuracy of EDTU for the diagnosis of hydronephrosis, and when normal, whether patients can be safely discharged.
