目的:为经腰背部直切口结扎睾丸静脉主干治疗复发性精索静脉曲张提供解剖学基础。方法:以左肾下极为０点平面,测量５９具正常成年男尸左输尿管(Ｕ)、左睾丸静脉(Ｖ)和左睾丸动脉(Ａ)之间的水平距离以及相交高度,统计分析其相互位置关系。结果:①Ｕ－Ｖ在０点平面的水平距离为０~３８ｍｍ,有９４．９%在２０ ｍｍ内;②Ｕ－Ｖ相交点距０点平面的垂直距离为－３７~６５ｍｍ,有７４．６%在０点平面上、下 ２０ ｍｍ内相交;③在０点平面,６９．５%的Ａ－Ｖ已相伴行,未伴行者的８３．３%相距在２０ｍｍ内。结论:根据数据分析提示:手术中先找到左肾下极和左输尿管;在肾下极平面,绝大多数的睾丸静脉可在输尿管两侧２０ｍｍ的范围内找到;虽大多数的动静脉在此高度已经伴行,但仍要注意区别未与静脉相伴而独立下行的睾丸动脉。
Objective: To provide an anatomical basis for the treatment of recurrent varicocele by lumbar spine straight ligation of testicular vein. Methods: The horizontal distance and the intersection height between the left ureter (U), the left testis vein (V) and the left testis artery (A) Positional relationship. Results: ① The horizontal distance between U-V and 0:00 plane is 0-38mm with 94.9% within 20mm. ② The vertical distance between U-V and 0-plane is -37-65mm with 74.6% At 0 o’clock plane, the next 20 mm intersect; ③ At 0 o’clock plane, 69.5% of A-V has been accompanied by line, 83.3% of unaccompanied persons within 20mm. Conclusion: According to the data analysis, the left lower kidney and the left ureter were found during the operation. In the lower polar level, the vast majority of testicular veins could be found in the range of 20mm on both sides of ureter. Although most of the arteries and veins Height has been accompanied, but still pay attention to the distinction between the vein is not accompanied by an independent downward descending testicular artery.
