MRU在上尿路梗阻诊断中的应用

Diagnostic Application of MRU in Patients with Upper Urinary Obstruction

目的:探讨磁共振水成像(MRU)在上尿路梗阻性疾病诊断中的价值。方法:对28例经B超和IVP怀疑上尿路梗阻患者进行了MRU检查,并分别与手术及病理结果进行比较。结果:28例中通过磁共振尿路水成像可以从不同角度清楚描述输尿管下段的形态,展示各种疾病的异常影像改变,定位诊断率100%,定性诊断的正确率为88.6%。结论:MRU诊断正确率高,无创且不受肾功能影响,并发症少,可作为上尿路梗阻病因学诊断的重要手段。

Objective ：To evaluate the diagnostic efficacy of MRU in patients with upper urinary obstruction. Methods：MRU was carried out in 28 cases of ureterohydronephrosis detected by B - uhrasonography and intravenous urography. All the images were contrasted with pathologic diagnoses and surgical findings. Results：The ureteral shape could be clearly seen from various film of magnetic resonance hydrography and abnormal image changes of various diseases could be revealed clearly. The accurate diagnostic rates for location and qualitative identification were 100% and 88.6% , respectively. Conclusion： MRU would reveal important information which might not be detected by IVU and the technique is noninvasive with no need of contrast media. It is recommended for detecting the location of upper urinary tract obstruction.
