Case Discussion
When it comes to kidneys stones they do not come much bigger than this. On the initial plain radiograph, it seems hardly comprehensible despite their projection over an enlarged reniform outline. Retained colonic barium was the other initial consideration, but this was dismissed. CT-KUB illustrates the magnitude of the urolithiasis.
