利尿前后二维及彩色多普勒超声诊断肾盂癌的结果比较

Comparison on diagnosis and differential diagnosis of color ultrasonography on renal pelvic carcinoma before and after diuresis

目的探讨利尿前后二维及彩色多普勒超声对肾盂癌的诊断价值。方法常规彩超检查双肾,发现肿瘤后,检测肿块大小、形态、回声、边界、血流显示分布情况,观测肿瘤与周围组织及周围器官的关系。对常规彩超不能确诊肾盂癌患者,行药物利尿后30min彩超检查双侧肾脏,借助集合系统分离暗区做声窗,分辨是否存在肿瘤,发现并确定肾盂肿瘤后,重复检测上述指标。结果利尿前超声诊断肾盂癌的诊断准率52.1%。利尿后超声诊断肾癌的诊断准率88.9%。结论利尿后使肾盂癌肿块显示更清楚,明显提高了肾盂癌的诊断符合率。

Objective To investigate the diagnostic value of two-dimensional and color uhrasonogrphy evaluation on 48 renal pelvi carcinoma patients. Method Deteccting kidney of two sides, when finding tumor tumror size morphology, echo, border, blood distribution, and the relationship between the tumor and neighbor tissue or organ was observed. Later 30 minutes after using urinate medicine, kidney of the both sides were again detected. Assistant by assemble system separating dark distrct as echo window authors also analysed whether it is tumor or repeating the detecting again. Result The accuracy of uhrasonography diagnosis was 52.1% before urination; but was 88.9% after urination. Conclusion Above method can more clearly improve the diagnosis of the renal pelvis in line with the accordiance rate thus has important clinical value.
