A discoid-shaped ectopic kidney located in front of the right common iliac artery was observed in a 71-year-old Japanese man. The right kidney was normally positioned, but the left kidney was not observed in the normal position. The ureter of the ectopic kidney descended laterally to the left ductus deferens. The ectopic kidney received three arteries which arose from the anterior aspect of the abdominal aorta. Two of the arteries supplied the left half of the kidney. The other supplied the right half and gave off two branches to the adipose tissue around the right kidney; these branches meant that this artery belonged to the right side. Venous drainage from the kidney was handled by two veins. One collected venous radicles from the right half of the kidney and flowed into the inferior vena cava; this vein belonged to the right side. The other served the left half and joined with the left lumbar vein, which finally drained into the left common iliac vein; this vein was attributed to the left side. The present ectopic kidney had a left-side ureter, and vascular supply on both the right and left sides. This disunity or dissociation of laterality in the vessels and the ureter seemed to be strongly related to the location of this ectopic kidney in the median region.
在一名71岁的日本男性中观察到一个盘状异位肾，位于右髂总动脉前方。右肾位置正常，但未在正常位置观察到左肾。异位肾的输尿管向左输精管外侧下行。异位肾接受三条起自腹主动脉前方的动脉。其中两条动脉供应肾的左半部分。另一条供应右半部分，并向右肾周围的脂肪组织发出两个分支；这些分支表明这条动脉属于右侧。肾的静脉回流由两条静脉处理。一条收集肾右半部分的静脉小支并流入下腔静脉；这条静脉属于右侧。另一条为左半部分服务，并与左腰静脉汇合，左腰静脉最终汇入左髂总静脉；这条静脉归属于左侧。目前的异位肾有左侧输尿管以及左右两侧的血管供应。血管和输尿管这种左右侧的不统一或分离似乎与这个异位肾位于正中区域的位置密切相关。
