Congenital ureteral valves are a rare cause of obstructive uropathy and the majority of cases are diagnosed only at surgery or autopsy. A case of congenital ureteral valve associated with an incompletely duplicated kidney is reported and the literature on ureteral valves is reviewed. Modern uroradiological and endoscopic diagnostic techniques should result in a more precise preoperative diagnosis. The high incidence of associated genitourinary anomalies, particularly duplication anomalies, suggests abnormal ureteral embryogenesis as an etiological factor in congenital ureteral valve formation.
先天性输尿管瓣膜是梗阻性尿路病的罕见病因，大多数病例仅在手术或尸检时才得以诊断。本文报告了1例与不完全重复肾相关的先天性输尿管瓣膜病例，并对输尿管瓣膜的相关文献进行了综述。现代尿放射学和内镜诊断技术应能实现更精确的术前诊断。相关泌尿生殖系统异常，尤其是重复畸形的高发病率，提示输尿管胚胎发育异常是先天性输尿管瓣膜形成的一个病因。
