Four patients presenting with high grade unilateral vesicoureteral reflux were discovered at surgery to have an unsuspected duplex system with a ureterocele associated with the upper pole of the refluxing kidney. No preoperative radiographic study was diagnostic for duplication or ureterocele but when studies were reviewed retrospectively subtle evidence suggesting this possibility could be identified in a few cases. This rare situation should be considered whenever massive unilateral vesicoureteral reflux is encountered.
4例表现为重度单侧膀胱输尿管反流的患者在手术中发现存在未被怀疑的重复肾系统，伴有与反流肾上级相连的输尿管囊肿。术前影像学检查均未诊断出重复肾或输尿管囊肿，但回顾性分析这些检查时，少数病例可发现提示这种可能性的细微证据。当遇到重度单侧膀胱输尿管反流时，应考虑这种罕见情况。
