摘要
目的:评价各影像学检查在输尿管非结石性梗阻(NCUO)定位定性诊断中的价值。材料与方法:总结分析50例NCUO病例IVP、RGP、CT、B超(US)及放射性核素(肾图)的定位定性诊断率及典型影像表现。结果:IVP的定位、定性诊断率59.5％、28.6％,诊断率取决于显影的优劣;RGP对非肿瘤性狭窄的定位诊断率92.9％,具有优势;CT对肿瘤的定性诊断率81.8％,优于其他方法;US的定位、定性诊断率78.9％、13.2％,主要价值在定位诊断,肾图起参考作用。结论:IVP应作为首选;RGP对定位、CT对肿瘤的定性具有优势;US宜与IVP联用;依据检查流程可减少检查的盲目性。
Purpose: To evaluate the value of various kinds of diagnostic imaging method in local and qualitative diagnosis of noncalculone ureteric obstruction (NCUO). Materials and methods: The local and qualitative diagnostic rate and typical image appearances of IVP,RGP,Cr,US and Renogram were analysed in 50 cases with NCUO. Results: The local and qualitative diagnostic rate of IVP were 59.5% and 28.6% respectively and the diagnostic rate was depended on the quality of the image. The local diagnostic rate of RGP for non-tumoral stricture is 92. 9% which showing some superiority. The qualitative diagnostic rate of CT for tumors was 81.8% which is superior to other methods. The local and qualitative diagnostic rate of US was 78. 9% and 13.2% respectively and its value was in local diagnosis. Renogram was merely for reference. Conclusion: IVP should be the first choice while RGP is good for localization and CT is good for qualitative diagnosis, it would be better to combine US and IVP. Applying examination flow map might reduce unnecessary usage of above methods.
