Which statement best describes imaging after a first urinary tract infection in a child?

• A. Radiologic studies are rarely indicated with first infection
• B. Ultrasound is always indicated
• C. Voiding cystourethrogram is routinely performed
• D. Imaging is never necessary

Answer: (A)

Imaging after a first febrile urinary tract infection in a child is not done routinely. The reason is to avoid unnecessary procedures, radiation exposure, and discomfort from invasive tests when there is a good chance there is no significant underlying anatomic problem. Imaging should be targeted based on the clinical scenario: if there are abnormal exam findings, persistent fever or symptoms suggesting obstruction, poor response to therapy, abnormal urinalysis or growth concerns, or there are recurrent UTIs, then selective imaging is warranted. A noninvasive renal-bladder ultrasound is often used to screen for major anatomical issues, but more invasive studies like voiding cystourethrography are reserved for cases where ultrasound is abnormal or there are recurrent infections or suspected reflux. Thus, after a single UTI, radiologic studies are not routinely indicated.
