摘要
目的:探讨磁共振尿路成像(magnetic resonance urography,MRU)对异位输尿管开口定位诊断的价值。方法:对17例平均年龄4.5岁女患儿行B超、静脉肾孟造影(IVU)、CT或膀胱镜插管造影检查,同时全部行MRU检查。结果:B超检查17例,发现发育不良小肾脏3例,单侧肾脏缺如1例,重肾及输尿管积水12例,未见异常1例;IVU检查7例,其中3例肾积水,未显影或显影不清4例。CT检查14例,3例发现发育不良的小肾脏及扩张的输尿管,11例重复肾上位肾积水。膀胱镜检查5例,其中2例发现异位开口;从异位开口插管造影,只显示输尿管扩张段。所有患者行MRU检查,均发现重复肾、异位输尿管形态走行和异位输尿管开口。结论:MRU具有非侵袭性、无肾功能依赖性、能较好地显示尿路解剖情况等优点,其三维结构可展示上尿路病理解剖改变,可作为B超及IVU等未能明确诊断的小儿输尿管异位开口的首选诊断手段。
Objective To explore the diagnostic value of magenetic resonance urography(MRU) in ectopic ureters.Methods Seventeen female children with ectopic ureter were examined by sonography,intravenous urography(IVU),computer tomography(CT),MRU and so on.The mean age of the female children was 4.5 years(7 months～12 years).Results Seventeen patients were examined by sonography,including 3 dysplasia little kidneys,1 kidney absence,12 duplex kidneys with hydroureter,1 normal.Seven patients were examined by IVV,includin...
