Single ectopic ureters terminating in the female genital tract are rare congenital anomalies caused by an abnormally lateral origin of the ureteric bud from the mesonephric duct in the three- to four-week embryo. The ureter remains intimately involved with mesonephric duct remnants, which acquire a communication with müllerian structures. Hysterosalpingography in a continent infertile patient outlined a single cervical ureter from a hypoplastic kidney draining into Gartner's duct remnants. No previous case of single cervical ectopic ureter has been reported without a müllerian anomaly, nor has a single cervical ureter been demonstrated on hysterosalpingography.
终止于女性生殖道的单一异位输尿管是一种罕见的先天性异常，由输尿管芽在胚胎三到四周时从中肾管异常侧向起源引起。输尿管与中肾管残余紧密相连，后者与苗勒管结构相通。一名非梗阻性不孕患者的子宫输卵管造影显示，一条来自发育不全肾脏的单一宫颈输尿管汇入加特内管残余。此前未见无苗勒管异常的单一宫颈异位输尿管病例报道，子宫输卵管造影也未显示单一宫颈输尿管。
