Pediatrics · Paediatric infections: urinary tract infection imaging

Sample item

A 5-month-old girl has a first febrile urinary tract infection that responds to treatment. Which investigation should be done?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Renal and bladder ultrasound

All infants with a first UTI need ultrasound to find obstruction or structural abnormality. A micturating cystourethrogram is added if the ultrasound is abnormal or infection recurs. DMSA is used to look for scarring later.

Option by option

  • A. CT of the abdomen

    CT gives high radiation and is not indicated.

  • B. Micturating cystourethrogram in every case

    Routine cystourethrogram is reserved for abnormal ultrasound or recurrence.

  • C. Intravenous urography

    Urography exposes the child to contrast and radiation, and is outdated.

  • D. Renal and bladder ultrasound (correct)

    Correct. Ultrasound is the first imaging study.
