通过42例成人尸体肾血管的解剖学研究发现:1.上极段动脉的前上极支越过上盏上部肾小盏的前方;后上极支越过上部肾小盏的后方.2.下极段动脉的前下极支横跨肾盂的前下方,沿下大盏或下组肾盏靠外侧的肾小盏后方行走;后下极支由后段动脉延伸,越过肾盂与肾大盏交界处或沿肾下组肾盏伴行.3.肾门外段静脉与段动脉分布相同,肾门内段静脉主干基本上也与段动脉伴行,但有丰富的静脉交通支,呈链状或环状围绕肾盏漏斗部,呈网状广泛附着于肾小盏,根据肾段血管分布的规律设计出肾极段切除术,手术要点是先阻断上极段
Anatomical study of renal blood vessels in 42 adult cadaver found that: 1. The anterior superior pole of the superior artery crossed the anterior upper small calyx of the superior upper pole; the posterior pole crossed the posterior pole of the upper small renal calyx.2. Paralysis of the anterior segment of the artery below the anteroposterior renal pelvis, along the next big or lower calyx by the outside of the small calyx rear walking; posterior pole branch by the posterior segment of the artery extends beyond the junction of the renal pelvis and renal calluses Or along the renal calyces accompanied by the next group .3.The segment of the external renal vein and segment artery distribution, the main segment of the renal portal vein is basically accompanied by segmental artery, but rich in vein traffic branch, was chain or Ring around the calyceal funnel Department, a wide reticular network attached to the small calyx, according to the rules of renal vascular distribution of the renal section resection, the main points of surgery is to block the upper section
