As the inflammatory process disin-tegrates the adjacent tissue, all traces of normal pelvic out- INFLAMMATORY DILATATION 101 line may become lost and the pelvis appear as a large,irregular sac with occasional areas scattered through theadjacent parenchyma. As with hydronephrosis, the re-tained fluid often dilutes the injected medium so that butone or two dilated calyces may appear dimly outlined. Itis usually unnecessary to make a pyelogram with advancedpyonephrosis, since the clinical and cystoscopic data usually. Fig. 129.—Inflammatory dilatation. suffice to identify the condition. However, where the in-flammatory process is of moderate degree and when thecystoscopic data are doubtful, the pyelographic evidencemay be of distinct value. In Fig. 129 the major calycesare irregularly extended and are clubbed at their areas the diffuse outline of the dilated minor calyces issuggestive of cortical necrosis. In Fig. 130 the areas ofcortical destruction are indicated by diffuse shadows ex-11 162 PYELOGRAPHY
