In Fig. 21the outline of the left renal pelvis is quite different from theright in that the isthmus of its upper calyx is elongated toan unusual extent. Ordinarily, there are three major calyces; there may, 60 PYELOGRAPHY however, be an increase or decrease from the usual frequently but two major calyces are visible, onemajor calyx rarely, if ever, occurs without the presence ofsome pathologic condition in the kidney. In Fig. 24 fourdistinct and separate major calyces are visible in the pelvesof both kidneys. Although the distention of the right pelvisis incomplete, it suffices to show the outline of the Fig. 25.—Normal pelvis. An increase in the number of calyces is frequently seen tobe due to the branching of the major calyx into two ormore secondary calyces. Such branching occurs morefrequently with the lower major calyx. In Fig. 25 but twomajor calyces are visible. The lower calyx divides intothree distinct branches, which may be regarded as secondarymajor calyces or as large minor calyces. In Fig. 18 fourmajor calyces are visible in both pelves, but the increase THE NORMAL PELVIS 61 in number is seen to be the result of division of the lowestmajor calyx into two branches. Actual increase of themajor calyces may be simulated by divisions of the majorcalyces at the various planes in the parenchyma. In a bilateral symmetric arrangement of the major calycesis visible. They are evidently four in number, but on closerinspection the lower two calyces aie seen to be divisions of
