Pyelography (pyelo-ureterography) a study of the normal and pathologic anatomy of the renal pelvis and ureter . rmal lateral limits of the renal pelvis are not asvariable as the horizontal.

Shouldthe pelvis lie in front of the vertebral column, or at a con-siderable distance away from it, its position must be re-garded as abnormal. Relation of Pelvis and Ureter.—The lower portion ofthe true pelvis usually tapers gradually into the upperureter, causing a pyramidal outline in the pyelogram. THE NORMAL PELVIS 1 The first portion of the ureter, extending as far as the firstpoint of narrowing, is usually broader than the ureterbelow it. This is illustrated in Fig. 13. The ureter usuallyleaves the pelvis at a point where the median and lateralborders meet. It may, however, leave the median borderof the pelvis at some distance above the lowest portion ofthe lateral border. Whenever the ureter leaves the pelvis. Fig. 38.—Normal pelvis. in an upward direction, it is evident either that the kidneyis movable and has rotated laterally or that a congenitalanomaly is present. When the ureter leaves the pelvis fromits lateral border, it may be inferred that either a horseshoekidney or an anomalous rotation exists. In Fig. 19 theright ureter leaves the pelvis in a lateral and cephalic di-rection, while the left leaves in a lateral and caudad di-rection. 72 PYELOGRAPHY The angle formed by the ureter with the lower surfaceof the pelvis is usually broad and rounded. When theangle is acute, it indicates either marked rotation as theresult of renal excursion or pelvic dilatation. In Fig. 39the angle between the ureter and the lower border of thepelvis (particularly on the left side) is acute. This is dueto the position of the kidney, since the pelvis itself is normal.
