Fig. 2. A dual calyceal system that had a bifid ureter originating from separate major calyx (MA) and renal pelvis (RP) in coronal section of the left kidney. The anterior ureter (arrowhead) arose from a RP that was divided into two MAs in the lower two-thirds of the kidney. This RP was located within the renal sinus. The posterior ureter (arrow) was directly connected to a MA in the upper third of the kidney, without the formation of a RP. MI, minor calyx; Med, medial; Sup, superior.
