Pyelography (pyelo-ureterography) a study of the normal and pathologic anatomy of the renal pelvis and ureter . cal of mechan-ical obstruction in the lower ureter. They are broad atthe apices, which gives them a triangular shape. Thepelvis is but slightly enlarged. The extent of ureteral di-latation is not completely shown because of insufficientdistention. Not infrequently, secondary infection occurs in theoriginal hydronephrosis. In such cases the clinical and cys-toscopic data may be masked by that of secondary infec-tion, and the existence of a purely inflammatory processmay be suspected.

With the greater enlargement in thecalyces and with irregularity of the general pelvic outline 128 PYELOGKAPHY a primary inflammatory etiology would be inferred. Withthe distention predominating in the true pelvis and char-acterized with more or less regularity of outline the originalmechanical etiology would be demonstrated. Occasionally,however, it is difficult to determine from the pelvic outlinewhether the inflammatory or mechanical influence wasprimary. With marked inflammatory changes in the pelvic V.
