Ectopia of the vas deferens into the ureter is a rare occurrence, frequently associated with anorectal anomalies. To date, 20 cases have been reported, accounting for a total of 26 vasoureteral communications, 6 of which are bilateral. Embryologically, ureteral ectopia of the vas deferens may be explained by an underlying defect in the proximal mesonephric duct or an abnormally cranial origin of the ureteric bud. We add the case of a newborn with an ectopic vas terminating into the ureter of a multicystic kidney.
输精管异位进入输尿管是一种罕见的情况，常与肛门直肠畸形相关。迄今为止，已报道20例，共有26处输精管与输尿管相通，其中6例为双侧。从胚胎学角度来看，输精管输尿管异位可能是由于近侧中肾管存在潜在缺陷或输尿管芽的起源异常靠上所致。我们补充了一例新生儿病例，其异位的输精管终止于多囊肾的输尿管。
