Risk Factors Predicting the Necessity of Renal Ultrasound in the Emergency Department.

Objectives: Renal ultrasound (US) is widely used for diagnosing renal pathologies, though few of them, such as obstructive uropathy, require emergent urological intervention. During on-call hours, when medical staff is limited, it is important to prioritize which renal US examinations will be done. The aim of this study was to evaluate patient risk factors to predict the necessity of emergent renal US in the emergency department (ED).

Sonographic evaluation of vascular injuries.

Objective: The purpose of this presentation is to highlight the color Doppler duplex sonographic features of procedure-related and blunt or penetrating trauma-related vascular injuries.

Methods: Different kinds of vascular complications such as pseudoaneurysms, arteriovenous fistulas, dissection, and thrombosis are discussed. Cases of vascular injuries in the extremities, neck, and abdomen are presented to illustrate the spectrum of sonographic appearances.
