Brief Summary

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

This study evaluates if trainees can accurately rule out dilation of the renal collecting system on ultrasound (hydronephrosis) using hand-carried ultrasound (HCU). Trainees will undergo a short 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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hand-carried ultrasound arm

This is the only arm of the study. It will be comprised of 154 inpatients who had a renal ultrasound ordered or performed within the past 4 hours. The intervention will be performing hand-carried ultrasound to evaluate for presence and degree of hydronephrosis.

Group Type EXPERIMENTAL

Hand-carried ultrasound

Intervention Type DEVICE

Hand-carried ultrasound of both kidneys to detect the presence or absence of hydronephrosis. Device used will be the lumify portable ultrasound equipped with the C5-2 curved array transducer (Philips, USA).
