• The most common aberration in renal vessel development is supernumerary (accessory) renal arteries (a).
• Approximately 25 % of adult kidneys present with 2 - 4 renal arteries (more common on left side). Supernumerary arteries arise from the aorta and follow the main renal artery to the hilum of kidney. Usually they are given superior to the main renal artery.
• Supernumerary arteries are twice as common as supernumerary renal veins (b).
