肾副动脉的出现率为24.17±2.7%,但双侧双肾动脉的出现较为少见.在解剖一具成年女性尸体标本时,见腹主动脉发至肾门的肾动脉每侧为上下两支.现报道如下:右肾动脉上支长50.80mm,起始处距主动脉裂孔52.48mm,始端外径为4.44mm,离肾门处36.07mm,分为两支入肾门,两分支入肾门处间距为2.96mmm.右肾动脉下支长52.32mm,起始处距主动脉裂孔72.18mm,始端外径为3.74mm.上下两支肾动在肾门外间距为13.82mm. The incidence of the secondary arteries was 24.17 ± 2.7%, but the occurrence of bilateral renal arteries was rare.An adult female cadavers were dissected from the abdominal aorta to the renal arteries, Now reported as follows: the right renal artery length 50.80mm, starting from the aortic hole 52.48mm, the beginning of the outer diameter of 4.44mm, 36.07mm from the renal door, divided into two into the renal door, the two branches into the kidney The distance between the door was 2.96mmm.The length of the right renal artery was 52.32mm.The distance from the aorta was 72.18mm at the beginning.The outer diameter of the beginning was 3.74mm.The distance between the upper and lower kidney was 13.82mm.
