Accessory renal arteries are found frequently--more often on the left side and occurring in as high as 30-35% of cases in some series. These arteries usually enter the upper or lower poles of the kidney. The main clinical significance of such arteries entering the lower pole is that they may obstruct the ureter and lead to hydronephrosis. We report the presence of accessory renal arteries found during routine dissection in an elderly female cadaver. The uniqueness in the variations noted in our cadaver included (1) a dual relationship of the ureters to the accessory renal arteries and (2) both the right and left ovarian arteries originating from their respective accessory arteries. Anomalous renal vessels arise as a result of the complicated development of the kidneys. Similarly, the aberrant origins of both the ovarian arteries observed here could be explained on an embryological basis.
副肾动脉很常见——左侧更为多见，在某些系列研究中发生率高达30% - 35%。这些动脉通常进入肾脏的上极或下极。此类动脉进入下极的主要临床意义在于它们可能会阻塞输尿管并导致肾积水。我们报告在一具老年女性尸体的常规解剖过程中发现了副肾动脉。在我们的尸体中所观察到的变异的独特之处包括：（1）输尿管与副肾动脉的双重关系；（2）左右卵巢动脉均起源于各自的副肾动脉。异常肾血管的出现是肾脏复杂发育的结果。同样，此处观察到的卵巢动脉的异常起源也可以从胚胎学角度进行解释。
