Twisted renal vessels producing an abnormal shape of the right kidney.

The kidneys and the renal vessels are subject to a wide variety of variations. We report a rare variation of the right kidney and right renal vessels in a 60-year-old male cadaver. The right kidney was pyramidal in shape and the hilum was directed anteriorly. The right renal vessels were twisted against each other, and the inferior vena cava had a kink to the right side. Knowledge of this variation may be useful for the nephrologists, radiologists and surgeons.
