Measure
Hand-carried Ultrasound Arm
This is the only arm of the study. It will include 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. Hand-carried ultrasound: 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).

SECONDARY outcome

Timeframe: Through study completion, up to an average of 1 day

Population: Data regarding costs were not collected by research team at the time of the study.

Direct costs in $ of hand-carried ultrasound will be calculated and compared to the costs of radiology performed ultrasound. For hand-carried ultrasound, this will include costs of purchasing the device, training costs, yearly depreciation of the hand-carried ultrasound device. For radiology performed ultrasound, this will include the sonographer's fee, radiologist fee for interpretation of the result, transportation fee by hospital transport and depreciation of the ultrasound machine.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Through study completion, up to an average of 1 day

Population: Data regarding image quality was not collected by research team at the time of the study.

Ultrasound image quality assessed by a blinded independent radiologist. The quality will be deemed either excellent, good, fair or poor by the radiologist.

OTHER_PRE_SPECIFIED outcome

Timeframe: Through study completion, up to an average of 1 day

Population: Data regarding technical difficulty of the study was not collected by the research team.

How technically difficult was it for the trainees to obtain the images (patient intubated, obesity etc.) as graded by the trainees who performed the ultrasound scans themselves. Trainees will grade difficulty using the following measurement scale (1) Technically easy: trainee able to get clear images of both kidneys within a timeframe of 10 minutes (2) Technically challenging: Trainee able to get clear images of kidneys but requiring more than 10 minutes of scanning time (3) Technically difficult: trainee unable to get clear images of both kidneys independent of time spent scanning.
