Complete obliteration of the pelvis it-self, such as occurs with neoplasm, would hardly be Fig. 264 the outline of the true pelvis is oval. The calyces.

The out-line of the true pelvis is irregularly oblong, and the calycesare largely obliterated. The course of the ureter may beobserved extending over the vertebral column as a curveddim streak. It is evidently displaced by the cystic enlarge- RENAL TUMOR 281 ment in the lower pole of the kidney. In Fig. 2(30 the leftpelvis is markedly compressed by the multiple cysts, sothat but a narrow streak remains. The calyces are com-pletely obliterated, and the true pelvis markedly flattenedand elongated. Upward and lateral displacement of thekidney is evident. The right pelvis shows abbreviation of
