Atoperation the shadow was found to be caused by an entero-lith lodged in a retrocecal appendix. A careful study of the exact relation of a shadow to theoutline of the pelvis usually enables one to differentiate be-tween extra- and intrarenal shadows. It will be found thata cortical stone is usually situated at or near the end of a.
