摘　　要：目的探讨磁共振尿路成像(MRU)对泌尿系统先天畸形疾病的诊断价值。方法对比分析58例经手术及病理证实的泌尿系统先天畸形患者的MRU及IVU影像学资料。结果 18例肾盂输尿管连接部狭窄病例,MRU全部显影,均明确诊断;IVU显示13例,可明确诊断,显影不良2例及未显影3例,均未明确诊断。12例先天性巨输尿管、15例输尿管口囊肿及4例腔静脉后输尿管病例,MRU及IVU显示清晰,均明确诊断。7例重复肾输尿管,MRU均明确诊断;IVU显示5例,明确诊断,2例显影不良,未明确诊断。2例神经源性膀胱,MRU均明确诊断;IVU显示1例,明确诊断,1例显影不良,未明确诊断。结论 MRU已成为泌尿系统先天畸形的重要检查方法,尤其对IVU不显影或显影不良时,MRU可作为首选检查。Objective To explore the value of MR urography（MRU） in the diagnosis of the urina- ry congenital abnormities. Methods The MRU and IVU images of 58 patients with urinary congenital abnormities were compared and analyzed. All the cases were pathologically proved. Results In 18 uret- eropelvic junction stenosis cases, on the MRU all the stenosis locations were displayed; but 5 cases were displayed, 2 cases were displayed incompletely, 3 cases undisplayed on the IVU. Displayed 12 congenital megaureters, 15 ureteral cysts, 4 retrocaval ureters were displayed all completely on both MRU and IVU. In 7 kidney and ureter duplication, on the MRU all were displayed completely; but 5 cases were displayed, 2 cases were displayed incompletely on the IVU. In 2 neurogenic bladders, on the MRU all were displayed completely; but 1 case displayed completed, 1 case displayed incompletely on the IVU. Conclusions MRU is the important technique in the diagnosis of the urinary congenital abnormities, es- pecially for the case displayed failure on IVU, MRU can be used as the first choice.
