A pyelo-gram recently made shows the pelvis practically normal in MECHANICAL DILATATION 133 outline, and with a capacity of 28 In Fig. 99 thecalyces, particularly the lower, are slightly dilated. Thisplate was made three months after labor, prior to whichthe patient had pyelitis of pregnancy and a small h3dro-nephrosis on the right side. It is clearly shown that themechanical dilatation is almost effaced following the re-moval of the etiologic factor. On the other hand, the outlineof well-marked hydronephroses frequently may not become.

As a rule, if the pelvis then remains dilatedit is because of cicatricial changes in the walls of the pelvis,the result of inflammation. In Fig. 100 the calyces and thepelvis are dilated to a moderate degree. Three years prior aplastic operation was made on the kidney for hydronephro-sis. Since the operation the patient was subjectively examination now shows the renal function to 134 PYELOGRAPHY be approximately normal despite the fact that the pelvisdid not resume the normal shape. Intrarenal Hydronephrosis.—Although usually hydro-nephrosis is characterized by marked distention of the truepelvis, occasionally the dilatation may be confined largelyto the calyces. This type of hydronephrosis has beentermed intrarenal. On section of the kidney the calyces
