Abstract

Present case report describes a case of bifid ureter arising directly from separate calyces and renal pelvis of the kidney. Incomplete ureter duplication on the left side in a 78-year-old male cadaver was found during an anatomy class. These ureters converged in a Y-shaped pattern just above the level of the anterior superior iliac spine. In the coronal section of the kidney, the anterior ureter arose from a renal pelvis that was divided into two major calyces in the lower two-thirds of the kidney. On the other hand, the posterior ureter was directly connected to a major calyx in the upper third of the kidney, without the formation of a renal pelvis. This anatomical variation has implications for diagnostic approaches, especially in the use of imaging techniques by urologists for the insertion of stents in the treatment of phyelonephritis.
