Renal calculi seldom change their position between examina-tions. Biliary calculi frequently change their position between ex-aminations (Fig. 15, 16). I shall now present some of that small group of troublesome situa-tions where the differentiation of the two conditions is most diffi-cult, and where the differentiation cannot be made from the physicalcharacteristics. Subsequently I shall show how these can be differ-entiated. Occasionally when an examination of the right kidney is made Cole: Right Renal Lithiasis and Gall-Stone 949. 950 INTERSTATE MEDICAL JOURNAL and the kidney outline is distinctly shown, there will appear withinthe kidney shadow a sharply defined, rounded calculus, casting auniformly dense shadow of relatively small size (Fig. 17). Natu-rally one would be prone to make a diagnosis of renal calculuswithout much hesitation when confronted with such a strikingpicture, but this is where careful differentiation many times savesan embarrassing situation. I have only recently seen such a casewhere a diagnosis of renal calculus was made by another roentgen-ologist, and the diagnosis was subsequently established as gall-stone. Fortunately this patient was not operated before the correctdiagnosis was established. The reverse of the foregoing example might just as readily hap-pen. One may get good, crisp plates showing a sharply definedgall-bladder, and lying within this shadow the same type of dense,rounded calculus may be observed. Again, one must be carefulto assure himself
