The areas of cortical destructionwhich extend beyond the calyces may be connected by nar-row isthmuses with the apices, so as to give a very irregularoutline to the pelvis. 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
