The ureter is seen to be verytortuous below the ureteropelvic juncture, and evidentlyleaves the pelvis posteriorly and from below instead of ina median direction. In Fig. 84 the greatly dilated major calyces are visible,with a distinctly pyramidal enlargement, broad at the. Fig. 84.—Hydronephrosis. apex and narrow at the base. The minor calyces are en-tirely effaced. The outline of the dilated true pelvis issuggested by a faint shadow underlying that of the majorcalyces. The pelvic outline is dim, probably as a result ofthe dilution of the injected solution by retained urine. Thecourse of the upper ureter is markedly tortuous, and evi- 116 PYELOGRAPHY dently leaves the pelvis posteriorly. The position of thecalyces would suggest rotation of the kidney. As the degree of pelvic dilatation increases the majorcalyces become shorter as well as broader. The abbrevia-tion of the calyx may proceed to such an extent that one ortwo irregular indentations in the otherwise rounded contourof the true pelvis alone may remain. In Fig. 85 the majorcalyces are shallow and open widely at their base into the
