A case is presented of an ectopic ureter opening into the seminal vesicle associated with hypodysplastic kidney in an infant. We reviewed 135 cases (139 ureteral units) of male ectopic ureter from the Japanese literature and, of the 139 ectopic ureters, 109 were single-system ectopic ureters, and 26 ureters were associated with the ureteral duplication. Sixty-three and 73 ureters opened into the urinary tract and seminal tract, respectively. In patients 15 years or older, 65 cases of ectopic ureter opened into the seminal tract and 33 cases opened into the urinary tract, whereas in children under 15 years, the ectopic orifice was located more often in the urinary tract (26 cases) than in the seminal tract (8 cases). Presenting symptoms differed according to the location of the ectopic orifice. Ectopic ureters opening into the urinary tract most often presented with urinary tract infection and abdominal or lumbar pain. On the other hand, voiding and ejaculatory symptoms as well as perineal or genital pain were characteristic in ectopic ureters opening into the seminal tract. Of the 83 associated renal segments that were surgically removed, dysplasia, hypoplasia and aplasia were found in 22, 24, 14 cases, respectively. It was noteworthy that 48 of the 53 single ectopic ureters opening into the seminal vesicle were associated with ipsilateral renal dysgenesis.
本文报告了一例婴儿异位输尿管开口于精囊并伴有肾发育不全的病例。我们回顾了日本文献中135例（139个输尿管单位）男性异位输尿管病例，在这139个异位输尿管中，109个为单系统异位输尿管，26个输尿管与输尿管重复畸形相关。分别有63个和73个输尿管开口于尿路和生殖道。在15岁及以上的患者中，65例异位输尿管开口于生殖道，33例开口于尿路，而在15岁以下的儿童中，异位开口更常见于尿路（26例）而非生殖道（8例）。根据异位开口的位置，临床表现有所不同。开口于尿路的异位输尿管最常表现为尿路感染以及腹部或腰部疼痛。另一方面，开口于生殖道的异位输尿管的特征性表现为排尿和射精症状以及会阴部或生殖器疼痛。在手术切除的83个相关肾段中，分别有22例、24例和14例发现发育异常、发育不全和发育不全。值得注意的是，在53个开口于精囊的单发性异位输尿管中，有48个与同侧肾发育异常相关。
