A routine cadaveric dissection in an adult male revealed the emergence of two renal veins at the hilum of the right kidney that presented two separate openings in the inferior vena cava (IVC), one above the other. At the hilum the segmental branches of the right renal artery were sandwiched between the two veins. An additional venous tributary was present posterior to the right renal pelvis. A single renal vein emerged at the hilum of the left kidney. The various tributaries observed on the right and left sides were measured. The possible developmental basis for this variation suggests the persistence of the embryonic pattern observed in the 22 mm embryo.
在一具成年男性尸体的常规解剖中发现，右肾门处出现两条肾静脉，它们在 inferior vena cava（下腔静脉，IVC）上呈现出两个上下分开的开口。在肾门处，右肾动脉的段支夹在两条静脉之间。右肾盂后方还有一条额外的静脉属支。左肾门处出现一条单一的肾静脉。对左右两侧观察到的各种属支进行了测量。这种变异可能的发育基础提示了在22毫米胚胎中观察到的胚胎模式的持续存在。
