摘　　要：目的分析重复肾和重复输尿管超声、静脉尿路造影（IVU）、螺旋CT尿路造影（CTU）及磁共振泌尿系统水成像（MRU）的影像学特点，比较各种影像学检查方法在重复肾畸形诊断中的优劣，探讨超声的诊断价值。方法对40例经手术证实的重复肾及重复输尿管病例的超声、IVU、CTU、MRU的影像学检查结果进行回顾性分析。结果40例重复肾患儿，左侧23例，右侧9例，双侧同时发生者8例。超声总体诊断符合率为80．85％；IVU总体诊断符合率为73．91％；CTU总体诊断符合率为83．78％，MRU诊断符合率为100％。发育型重复肾中有4例为“Y”形输尿管，其余重复肾均有完全重复的输尿管。合并输尿管末端囊肿22例。结论在小儿肾重复畸形的诊断中，不同影像学技术结合可以做到优势互补，提高诊断率，为临床提供可靠依据。超声已成为，临床首选影像学检查方法。Objective To investigate the diagnosis value of ultrasound in the duplex kidney and duplication of ureter, which compared with intravenous urography （ IVU）, computed tomography ureter （CTU） and magnetic resonance utter （MRU） and realize the superior or inferior in those imaging exami- nations. Methods In 40 cases randomly selected who were confirmed suffering from the duplex kidney by operation, their image results were collected and retrospectively analyzed. Results In those randomly selected patients, the accuracy rate of diagnosis of ultrasound was 80. 85% and the IVU was 73.91%, CTU and MRU was 83.78% and 100%. Conclusions In the diagnosis of ultrasound in the duplex kidney and duplication of ureter, four kinds of imaging examinations can have complementary advantages and improve the accuracy of diagnosis. And ultrasound is a reliable and accurate method for the diagnosis in clinic.
