The association between vesicoureteral reflux, parenchymal scarring, and urinary tract infection in children with nonduplicated collecting systems is well known, but similar data for children with duplex systems are sparse. The purpose of this study was to determine the prevalence of duplex anomalies in girls with a history of urinary tract infection and to compare the prevalence of associated reflux and parenchymal scarring to that found in girls with nonduplex systems. Voiding cystourethrograms and excretory urograms of 560 girls referred for evaluation of urinary tract infections were reviewed retrospectively. Duplex collecting systems (complete and partial) were found in 8%. Vesicoureteral reflux was seen in 69% of complete duplex systems and in 22% of partial duplex systems. Parenchymal scarring was evident in 17% of those girls with complete duplication and in 6% of those with incomplete duplication. The statistics for girls with partial duplication were very similar to those for girls with urinary tract infection and nonduplex systems. These data indicated that girls with partial duplex systems clinically appear similar to those girls with anatomically normal systems. Girls with complete duplex systems had a higher prevalence of vesicoureteral reflux and associated anomalies, indicating a need for closer follow-up and/or surgical intervention.
在非重复集合系统的儿童中，膀胱输尿管反流、实质瘢痕形成和尿路感染之间的关联已为人熟知，但关于重复集合系统儿童的类似数据却很稀少。本研究的目的是确定有尿路感染病史女孩中重复异常的患病率，并将相关反流和实质瘢痕形成的患病率与非重复系统女孩中的患病率进行比较。对因尿路感染接受评估的560名女孩的排尿性膀胱尿道造影和排泄性尿路造影进行了回顾性分析。发现8%的女孩有重复集合系统（完全型和部分型）。在69%的完全重复系统和22%的部分重复系统中可见膀胱输尿管反流。在17%的完全重复女孩和6%的不完全重复女孩中实质瘢痕形成明显。部分重复女孩的统计数据与有尿路感染且为非重复系统的女孩非常相似。这些数据表明，部分重复系统的女孩在临床上与解剖结构正常的女孩相似。完全重复系统的女孩膀胱输尿管反流及相关异常的患病率较高，这表明需要更密切的随访和/或手术干预。
