Above this point the ureter as well aspelvis are normal in outline. With stone in the lower ureter the renal pelvis is fre-quently, though not always, dilated to a greater or less ex-tent. Flattening and broadening of the minor calyces andelongation of the major calyces are the first evidences of 240 PYELOGRAPHY ureteral obstruction visible in the pelvic outline. The dila-tation in the calyces usually remains proportionately largerthan that in the true pelvis. When the lower ureter is butpartially filled by the injected solution and its outline is un-certain, the existence of ureteral dilatation may be inferredfrom evidence of dilatation in the renal pelvis, a fact which
