In Fig. 292 the two pelvesof a horseshoe kidney are clearly visible. The upper pel-vis is normal in size, while the lower pelvis is distinctlydilated because of a constriction of the lower ureter. Theureter appears to be doubled back on itself before enteringthe posterior surface of the pelvis. The distance separating 308 PYELOGRAPHY the pelves shows that bisection of the kidney would be possible.

In a unilateral pyelogram the possibility of a fused or horseshoe kidney should be considered if the ureter leaves the pelvis in a lateral direction instead of the normal Fig. 292.—Fused kidney—hydronephrosis in lower pelvis. In Fig. 293 the pelvis and ureter of the left segment of ahorseshoe kidney are outlined. They are markedly dilatedas the result of mechanical obstruction in the lower portionof the ureter and because of secondary infection. Of par- CONGENITAL ANOMALY 309 ticular interest is the direction in which the ureter leaves thepelvis. The ureteropelvic juncture is at the lateral borderof the pelvis, instead of the usual median.
