Review of Imaging Findings in Urinary Tract Infections

Acute urinary tract infection diagnosis is primarily performed on clinical grounds. Diagnostic imaging is, however, often necessary as part of the workup for poor response to treatment, to evaluate causative or contributory factors, complicated infections and chronic presentations. Appropriate knowledge of the most relevant radiological findings in urinary tract infections provides pertinent differential diagnosis and guides clinical management, including emergent and aggressive interventions. In this article we review ultrasound and CT imaging findings of acute and chronic urinary tract infections.
