Non-contrast-enhanced abdominal dual-energy CT accurately depicts a urinary stone in the right distal ureter (A). Dual-energy postprocessing demonstrates the stone to be completely composed of non-uric acid as indicated by blue colour coding (B, arrow). None of the partitions of the stone consists of uric acid (red colour coding, not shown)
