Pyelography (pyelo-ureterography) a study of the normal and pathologic anatomy of the renal pelvis and ureter . Fig. 283.—Duplication of the Fig. 284.—Duplication of the pelvis. 298 PYELOGRAPHY stead of combining as they near each other, merely crossand pursue their independent courses. When the pelvis is duplicated completely, the lower pelvisis usually larger and more completely formed. The upperpelvis is usually smaller, has fewer calyces, and is oftenrudimentary. This disparity in size occurs so frequentlythat if, in the course of routine pyelography, the outline ofthe pelvis is unusually small and high lying, duplication ofthe pelvis should be inferred and attempts made to outlinethe lower pelvis. In Fig. 284 the lower pelvis is slightlylarger and is more completely formed than the upper. InFig. 282 the difference in size between the upper and lowerpelves is striking. The outlines of both pelves are slightlydilated as the result of chronic infection. In Fig. 283 thesize of the two pelves is approximately equal. In Fig. 277,however, the upper pelvis is larger and more completely de-veloped than the lower. A possible
