50名男性尸体(10名新生儿及40名成人),将着色的低粘稠度树脂注入睾丸静脉以取得静脉模型,6例有精索静脉曲张及5例无精索静脉曲张病人作手术中静脉造影。结果尸体解剖示在L_4水平睾丸静脉分为内支及外支,前者有输尿管支及与对侧静脉的交通支(55％),最终进入肾静脉或下腔静脉;后者有结肠支(76％)及与肾包膜静脉的吻合支(100％),终止于肾周脂肪中。静脉造影未见瓣膜显示,精索静脉曲张组的睾丸静脉无张力,且无泵的性能。作者认为交通支的存在及静脉的无张力可解释精索静脉曲张的发生及如何影响精子发生,结肠-生殖道-输尿管的吻合是血吸虫到达上泌尿道的途径,丰富
Fifty male bodies (10 newborns and 40 adults) were injected into the testicular vein with colored, low-viscosity resin to obtain a venous model. Six patients had varicoceles and five patients without varicoceles undergoing surgery Venography. Results The autopsy showed that the testicular vein at the level of L_4 was divided into internal branch and external branch, the former had ureteral branch and traffic branch (55%) with the contralateral vein and finally entered the renal vein or inferior vena cava. The latter had colonic branches %) And anastomosis with renal capsule veins (100%), terminating in perirenal fat. No valvulography was found on venography, with no tension in the testicular veins of the varicocele group and no pump performance. The author believes that the existence of traffic branch and venous tension can explain the occurrence of varicocele and how to affect spermatogenesis, colon - reproductive tract - ureter anastomosis Schistosoma access to the upper urinary tract, rich
