The Technique of Roentgenological Examinations of the Urinary Tract 2- two positions, we feel reasonably surethat the presence of a ureteral stone isindicated. In the case of a small calcifiedgland below the ureter, one anteriorposterior plate of the catheterized uretermay show a shadow directly in contactwith the catheter. Another exposuregiving a marked oblique or lateral view,however, may disclose a considerable spaceintervening between the shadow and the them (Fig. 6, a and h). With a problemof this kind, a ureterogram should bemade which will give the exact size of thelumen of the ureter, with the extent ofdilatation, and usually the point of con-striction (Fig. 7, a and h). This methodis much more accurate than the waxed-tip catheter, which may be introducedinto the dilated ureter, and at no timecome into contact with the calculus.

Frecjuently,particularly in the case of a large calculus,the ureter becomes dilated from over-distention due to obstruction. This dis-tention may be enormous, so that theureter may measure more than an inch indiameter. With this type of case, both thecatheter and calculus may be in the ureter,with a considerable distance between When examination of the films showsno evidence of calculus, we should reportthat the roentgenological findings arenegative to calculus; but to this report weshould add the statement that in a smallper cent of cases, calculi may be presentin the ureter or kidney which will not beseen on the roentgenograms. We believethat in some cases, this lack of vi
