Gross anatomy of the horseshoe kidney in 2 Japanese patients clarified that the long renal pelvis consists of 4 funnel-shaped tubes (Pelvis renalis ramificata) in the hilus opening in the ventral direction, and that the 4th tube can drain half of the isthmus. The renal artery, on the other hand, divided into 2 dorsal and ventral branches around the long pelvis in the hilus, the latter of which gave rise to the branches to the first and second tubes, but the former the branch to the third. Another artery arose from the lower portion of the abdominal aorta to supply the 4th tube in the half of the isthmus. This method of blood supply was principally in good accordance with that described by Graves (1971) except for a branch from the inferior mesenteric artery to the isthmus. These pelvic ramification and pattern of blood distribution were summarized in Fig. 9.
对2例日本患者马蹄肾的大体解剖学研究表明，长肾盂由4个漏斗状管（分支肾盂）组成，在肾门处朝腹侧开口，且第4个管可引流峡部的一半。另一方面，肾动脉在肾门处围绕长肾盂分为2支背侧和腹侧分支，后者发出分支至第1和第2个管，但前者发出分支至第3个管。另一支动脉发自腹主动脉下部，供应峡部一半的第4个管。除了发自肠系膜下动脉至峡部的一支分支外，这种血液供应方式与Graves（1971年）描述的基本一致。这些肾盂分支和血液分布模式见图9。
