The aim of this study was to investigate the variation of the renal arteries in Hasak sheep. Six animals was used for this purpose. Renal artery and its segments were prepared using standard corrosion cast techniques and examined. An electronic caliper was used to measure the length and diameter of the renal arteries. Each kidney was vascularized by a corresponding single renal artery that arose from each side of the abdominal aorta. The renal arteries divided, forming a dorsal and a ventral branch. The dorsal and ventral branches gave off the a.interlobaris, a. arcuate and a. interlobularis, respectively. No anastomoses were seen all materials. In the left kidney, one interlobar artery, the originated from the ventral branch was nourished dorsal surface.
