肾动脉的变异是腹主动脉分支中最为常见的。根据临床方面的资料,变异的肾动脉往往是肾积水的成因之一,因而在手术时早被外科学家所注意。根据文献的记载,可将进入肾胜的动脉分为二类:第一类指起源于腹主动脉经肾门而进入肾脏者称为臂动脉;第二类是指起于腹主动脉或其分支,但不经肾门而入肾者名为肾付动脉或肾迷走动脉。肾动脉的变异情况,在各家所报导的资料中亦并不一致。就肾动脉的支数而言,据TOHKOB氏的研究,一侧肾脏有二支肾动脉者占20％;Seldowitsch氏的资料则占30.5％;
Renal artery variability is the most common branch of the abdominal aorta. According to clinical data, the variant renal artery is often one of the causes of hydronephrosis, and therefore has been noted by surgeons at the time of surgery. According to the literature, can be divided into two categories of arteries into the kidney wins: The first refers to the origin of the abdominal aorta through the kidney and into the kidneys are called the arm artery; the second category refers to the abdominal aorta or its Branches, but not through the renal portal into the kidney called renal artery or renal vagal artery. The variability of renal arteries is also inconsistent with the information reported by various departments. For the number of renal arteries, according to TOHKOB’s study, there are two renal arteries in one kidney accounting for 20%; Seldowitsch’s information is 30.5%;
