Sample item

Which CT examination is highly sensitive for suspected ureteric stone in many nonpregnant adults?

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

The answer and the reasoning

B. Non-contrast CT of kidneys, ureters, and bladder

Non-contrast CT of the kidneys, ureters, and bladder is highly sensitive for urinary calculi and can identify obstruction or alternative causes of flank pain, while radiation exposure should still be justified.

Option by option

  • A. Contrast-enhanced brain MRI

    Brain MRI does not assess urinary tract stones.

  • B. Non-contrast CT of kidneys, ureters, and bladder (correct)

    Correct: non-contrast CT KUB is commonly used for suspected ureteric calculus.

  • C. Plain chest radiography

    Chest radiography is not sensitive for ureteric calculi.

  • D. Nuclear thyroid scan

    Thyroid scanning is unrelated to flank pain from stones.
