Classically, a single renal artery supplies, and a single renal vein drains each kidney. The morphology and variations in the renal vascular structures are of great importance when performing any type of renal surgery. The present case describes a rare combination of renal vasculature variation in a formalin-fixed, Chinese male cadaver. In this case, the left kidney is drained by a main renal vein (MRV) and an inferior renal vein (IRV), the latter might be the remnant of the left dorsal renal vein during the embryonic period. Two sets of renal arteries are present in this case, possibly due to persistent mesonephric arteries during embryonic development. Describing such anatomical variations is not only of academic interest but also important to help radiologists with the correct interpretation of image examinations and for surgeons to be prepared in advance.
经典情况下，单一的肾动脉供应每个肾脏，单一的肾静脉引流每个肾脏。在进行任何类型的肾脏手术时，肾血管结构的形态和变异都非常重要。本病例描述了一例经福尔马林固定的中国男性尸体中罕见的肾血管变异组合。在该病例中，左肾由一条主肾静脉（MRV）和一条肾下静脉（IRV）引流，后者可能是胚胎期左背肾静脉的残余。该病例存在两组肾动脉，可能是由于胚胎发育过程中中肾动脉持续存在所致。描述此类解剖变异不仅具有学术意义，而且对于帮助放射科医生正确解读影像检查以及让外科医生提前做好准备也很重要。
