摘　　要：【目的】探讨CT在重复肾输尿管畸形诊断中的应用价值。【方法】回顾性分析手术证实的40例重复肾静脉尿路造影（IVu）资料及CT表现特点，结合临床资料分析其影像学表现特征。【结果】40例重复肾中发育型5例，积水型32例，发育不良型3例，以积水型多见。主要CT表现：巨输尿管型之重复输尿管常呈肠管状扩张而相连的重复肾萎缩甚小；积水型呈重复肾不同程度囊状扩张，重复输尿管小囊影与圆点状显影的下肾段引流输尿管致密影相贴呈“印戒征”。伴发输尿管囊肿6例，输尿管异位开口12例。【结论】重复肾输尿管畸形的cT表现典型，CT是诊断此病的首选影像学方法。[Objective] To discuss the value of computed tomography （CT） in the diagnosis of renal dupli- cation in children. [Methods] Forty cases of renal duplication proven by sm;gery were analyzed with clinical, IVU and CT data, focusing on the radiological features. [Results] of all the cases, there were 32 hydronephrosis type, 5 developmemal type and 3 congenital megaloureter type. CT manifestations of congenital megaloureter were intestinal canal dilation of renal duplication and very small consecutive renal duplication. CT manifestations of hydronephrosis were capsular dilation of renal duplication and the ＂signetring＂ sign formed by the capsular shadow sticking to pykno-shadow of lower segment of draining ureter with punctiform image. There were 6 cases complicated with ureterocele and 12 cases with ectopic ureter. [Conclusion] The CT findings of renal duplication are typical. CT is the first choice of imaging methods for diagnosing this disease.
