Although themajor calyces are probably not fully distended, they arefairly well outlined and are but slightly dilated, while theterminal irregularities are effaced. The intercalyx papillaeare unusually well preserved. Considerable difficulty may be found in differentiatingthe early hydronephrosis from the large normal pelvis,since the outline of either the true pelvis or of the majorcalyces in a normal kidney is not infrequently of unusual.

In , although the true pelvis is unusually large, the terminalirregularities of the minor calyces are normal and there is nobroadening or elongation of the major calyces. The ab-sence of projecting papillae and the direct communication ofthe minor calyces with the true pelvis are unusual. In the calyces, both major and minor, are seen unusuallybroad. The terminal irregularities are fairly well preserved,however, and the papillary indentations are well defined. MECHANICAL DILATATION 105
