Pyelography (pyelo-ureterography) a study of the normal and pathologic anatomy of the renal pelvis and ureter . 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.

An unusual number of majorcalyces extend from a diminutive true pelvis in Fig. upper and lower major calyces subdivide into twosecondary calyces. The pelvis is situated at an abnormallylow level. The middle calyx is apt to be smaller than the other two,and may even be very rudimentary or absent entirely. It 62 PYELOGRAPHY
