Answer

Ultrasonography of the urinary tract has replaced intravenous pyelography (IVP) as the imaging study of choice in children with UTI. The AAP Clinical Practice Guidelines recommend routine ultrasonography of the urinary tract after a first febrile UTI in children aged 2-24 months. [3] Ultrasonography in these cases seldom provides information that changes management, however.

The clinician's judgment should guide the decision regarding imaging studies, rather than a rigid rule. Urinary ultrasonography is safe, noninvasive study, and easy to perform. It is useful in excluding obstructive uropathy, as well as in identifying a solitary or ectopic kidney and, in some cases, moderate renal damage caused by pyelonephritis.
