Hand-carried ultrasound is an increasingly popular imaging modality and is widely used by emergency physicians, intensivists, trauma doctors and cardiologists. Renal ultrasonography is commonly ordered for patients with acute kidney injury, with a main focus on identifying obstruction of the collecting system, a rare but potentially reversible cause of acute kidney injury. This study's aim is to evaluate if nephrology and internal medicine trainees can accurately rule out dilation of the renal collecting system on ultrasound (hydronephrosis) using hand-carried ultrasound (HCU). Trainees will undergo a short, uniform and well described ultrasound training program. Patients will be adults that are hospitalized and have acute or subacute kidney dysfunction. The investigators will assess sensitivity, specificity, positive and negative predictive value of HCU compared to radiology performed ultrasound, and calculate potential cost savings to the patient and to the healthcare system.
