Not in-frequently, however, such areas cause shadows which maybe confused with actual lithiasis. Occasionally stones mayactually be present in the kidney either coincidental or sec-ondary to the tuberculous process. Shadows caused by suchcalcareous foci can usually be identified by means of cys-toscopic examination and urinalysis, although it may attimes be difficult to do so. The demonstration in the pyelo-gram of the changes in the pelvic outline usually accom-panying tuberculosis would be of aid in identifying thecondition.
