In Fig. MECHANICAL DILATATION 107 68 the outline of the pelvis of the right kidney is distinctlylarger than that of the left. Any doubt as to the existenceof dilatation in the right pelvis would be excluded by com-parison of the two pelves. In Fig. 71 the true pelvis of theleft kidney is seen to be considerably larger than that of theright. The calyces are broadened and the terminal ir-regularities lost to some extent. On overdistention the.

Care must be taken to show the outhne of the pelvis ofthe kidney fully distended in order to demonstrate theseearly changes. If the calyces were but partially filled, the 108 PYELOGRAPHY normal terminal irregularities of the minor calyces mightnot be shown, and with a normally broad major calyx theresulting pyelogram might suggest the early changes of abeginning hydronephrosis. Furthermore, unless the pelvisis fairly well distended, the size of the major calyces maynot appear to be abnormally large, even in a well-markedhydronephrosis. In Fig. 75 the true pelvis is evidently
