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.
采用腐蚀铸型法对100具尸体肾脏的肾内动脉模式进行了研究。肾动脉异常起源罕见，仅占3%。71%的肾动脉在肾外分支，16%在肾内分支，11%在肾门处分为前后分支。1%的肾动脉未分为两支，而是延续为前支并分为上、中、下段动脉。前支的分支模式有5种不同变异。后段动脉有3种不同模式。尖段动脉起源的变异分为7种类型，下段动脉起源的变异分为5种类型。还观察到上、中段动脉起源的变异。所有段动脉的肾内分支模式均有变异。
