Bilateral asymmetrical multiple renal arteries associated with the left testicular artery
open access
Abstract
We found 3 right and 2 left renal arteries with asymmetrical origins in a 61-year-old Korean male cadaver, whose cause of death was ‘laryngeal carcinoma’. According to a previous classification, the first and second right renal arteries correspond to the early division and other renal arteries — to the extra renal arteries, except the first left renal artery as a typical renal artery. The third right renal artery ran anterior to the inferior vena cava to the inferior pole of the kidney. The first and second left renal arteries were associated with the inferior suprarenal artery and the testicular artery, respectively. The bilateral asymmetry in the number of renal arteries can be explained by the embryological development, degeneration and persistence of the renal artery in the process of ascending of kidneys.
