Overview
Radiological examinations are rarely indicated in the acute phase of a urinary tract infection. An exception is when an obstruction of a ureter is suspected in a patient with signs of pyelonephritis. In children with pyelonephritis or with recurrent cystitis, radiological examinations for identification of congenital anatomical defects and/or ureteral reflux should be performed after treatment of the acute infection. For detection of vesicoureteral reflux in children, contrast-enhanced ultrasound is recommended as a better alternative to micturating cystourethrography.
