Whenthe pelvis appears irregular and markedly dilated, and whenthe calyces extend irregularly to a considerable distance, theparenchyma will usually be found involved in the inflamma-tory process to such an extent that nephrectomy will benecessary. On the other hand, occasionally the pelvic outlinewill show but moderate changes and still the functional 216 PYELOGRAPHY capacity of the kidney may be markedly diminished as theresult of the chronic pyelonephritis. In Fig. 192 the irregularareas outline pyonephrotic calyces caused by multiple corticalstones. It is apparent that the degree of cortical destructionwill necessitate nephrectomy. In Fig. 193 a similar con-dition is apparent.
