| 摘 要： | 目的总结下腔静脉后输尿管的影像表现,探讨磁共振尿路成像在该病诊断中的价值。方法回顾性分析9例经手术证实的下腔静脉后输尿管的影像表现,所有病例均行常规磁共振尿路成像MRI及MRU检查;9例行腹部超声检查;8例行腹平片(KUB)及静脉肾盂造影(IVP),其中3例加做逆行肾盂输尿管造影(RUP);3例行中下腹部、盆腔CT检查。结果本组9例下腔静脉后输尿管均发生于右侧,其中8例为Ⅰ型(低袢型),右输尿管呈鱼钩形或"S"形改变;1例为Ⅱ型(高袢型),右输尿管呈"倒置J"形。超声准确诊断1例、静脉肾盂造影(IVP)结合逆行肾盂造影(RUP)检查,准确诊断6例。3例CT检查均能准确诊断。常规MR横断T2加权(MRT2WI)结合MRU检查,8例能准确诊断,诊断准确率为89%。结论 MRI对该病的诊断准确率非常高,而且对人体无生物学损害,具有很高的临床实用价值。

| Abstract: | Objective To summarize the imaging charactars of retrocaval ureter and investigate the clinical application value of magnetic resonance imaging(MRI) in diagnosis of retrocaval ureter.Methods Nine cases of retrocaval ureter confirmed by surgery were enrolled in the study.MR examination including conventional abdominal scanning sequence and magnetic resonance urography(MRU) and ultrasound examination were performed in all the patients.Eight of nine patients were undergone intravenous pyelography(IVP),and thre... |
