上尿路梗阻的影像学诊断评价

Evaluation of Imaging Diagnosis of Urethremphraxis on Upper Urinary Tract

目的 探讨和评价影像检查对上尿路梗阻的诊断价值。方法 对经临床治疗和手术病理证实的 13 5例上尿路梗阻进行了回顾性分析 ,重点分析B超、X线和CT对上尿路梗阻的检出、定位和病因的诊断。结果 上尿路梗阻的检出率 :B超明显高于X线和CT(P <0 .0 1)。定位正确率 :X线、CT明显高于B超 (P <0 .0 1)。三项联合检查定位正确率高达10 0 %。病因确诊率 :CT明显高于B超、X线 (P <0 .0 1) ,三者联合检查的确诊率 97.8%。结论 影像学检查对上尿路梗阻诊断起决定性作用。三种检查方法各有所长 ,三项联合检查最佳 。

Purpose To research and evaluate the diagnostic value of imaging examinations to urethremphraxis on upper urinary tract. Methods To analyse 135 cases who were diagnosed urethremphraxis on upper urinary tract after clinical treatment and operational pathological examination.The emphasis was to analyse the application of B us,X ray and CT in diagnosis of finding,locating and causing of. Results The finding rate of B US was higher than the other ( P <0.01).The right location rates of X ray and CT were higher than B US ( P <0.01),and it can be up to 100% if we used the three together.The accurate cause diagnostic rate of CT was higher than the other significantly,and it can be up to 97.8% using them together. Conclusion Imaging examination play a decisive role in the diagnosis of urethremphraxis on upper urinary tract,and each has its merit.However,using them together is the best.We should pay more attention to the application of combined methods.
