| 摘 要： | 目的 比较泌尿系梗阻的各种影像学诊断方法，讨论磁共振尿路造影(MRU)对泌尿系梗阻的诊断意义。方法 分析23例患儿术前行MRU检查的资料，与B超、静脉尿路造影(IVU)、逆行尿路造影、CTU等影像学诊断资料进行对比。结果 23例B超检查15例显示明确，静脉尿路造影有7例不显影或显影不清，CTU检查12例，其中8例显影，4例显影不清楚。MRU检查23例，均显影清楚。结论 MRU能显示无功能性肾脏集合系统，还有无需碘造影剂的优点，在儿童泌尿系梗阻辅助检查中有着重要作用。

| Abstract: | Objective To compare and evaluate diagnostic role of various imaging manifestation in the urinary tract obstruction. Methods 23 cases with urinary tract obstruction underwent B-ultrasound scanning, intravenous phelography(IVP), retrograde urography, CT scanning and magnetic resonance urography (MRU), and their findings were compared. Results B-ultrasound showed hydronephrosis in 15 cases of them, IVP provide for poor renal image in 7 cases. CT showed hydronephrosis in all 8 examined cases. MRU produced a good image in all cases. Conclusions Both B-ultrasound and IVP can be used as a first choice imaging for diagnosis of ureteral obstruction, MRU has the advantages of non-invasiveness, no ionizing radiation and could show the nonfunctional renal collecting tubules system.So it has important diagnotic value in congenital urinary tract obstruction of children. |
