title: Intrarenal arterial pattern of human kidney--corrosion cast study.
abstract: Study of intrarenal arterial pattern of kidney by corrosion cast method has been carried out on 100 kidneys obtained from post mortem bodies. The abnormal origin of renal artery is rare --only 3 percent. Renal artery divided extrarenally in 71 percent, intrarenally in 16 percent and at the hilum in 11 percent cases into anterior and posterior divisions. Renal artery did not divide into 2 divisions but continued as anterior division and divided into upper, middle and lower segmental arteries in one percent. The branching pattern of anterior division shows 5 different variations. Posterior segmental artery showed 3 different patterns. Variations in the origin of apical segmental artery were divided in 7 types and that of lower segmental artery in 5 types. The variations in origin of upper and middle segmental arteries were also observed. There were variations in the intrarenal branching pattern of all the segmental arteries.
