Human doubled renal and testicular arteries.

ABSTRACT

Doubled renal and testicular arteries were found in a well-developed 69-year-old caucasian male. The right kidney had two renal arteries, one at its usual midorgan (hilar) position and one inferior polar. One testicular artery arose from the mid-point of the usual renal artery, passed under the renal vein at its junction with the inferior vena cava, and then crossed over the inferior polar renal artery. The second testicular artery arose from the inferior polar renal artery near its origin from the abdominal aorta. The two testicular arteries remained doubled throughout their course and both entered the right testis at separate sites on the organ. The inferior vena cava passed under the inferior polar and over the superior testicular artery and the superior renal artery.
