The lower calyx is probablylargely effaced by the tumor tissue. The drainage of the injected fluid from the ends of thetumor-deformed calyces may be very slow. The demonstra-tion of the opaque medium retained in the calyces for morethan twenty-four hours after the pyelogram is made maybe of corroboratory value in the diagnosis of renal Fig. 246.—Renal tumor—neoplasm. A single small area of the injected fluid may be seen at somedistance from the true pelvis. In Fig. 247 scattered areasof colloidal silver are visible over the right kidney plate was made twenty-four hours subsequent to Fig,244, and demonstrates the slow drainage of the injectedmedium which occasionally occurs. Encroachment on the Pelvic Lumen.—When the tumorinvolves the true pelvis to any great extent, the usual re- 260 PYELOGEAPHY suit is encroachment on the pelvic lumen. With a moderatedegree of involvement but one portion of the pelvis may beinvaded; with general involvement of the kidney, eitherirregular narrow spaces may remain or total obliteration ofthe true pelvis may result. In case of the latter, no evi-dence of the injected medium would be found in the kidneyarea, but it would be seen extending as far as the uretero-
