摘要
目的提高超声诊断移植肾排斥反应准确率。方法对23例移植肾的超声检查结果和肾活检病理结果进行回顾性分析和总结。结果归纳出移植肾三类排斥反应的超声图像特征。结论二维超声和彩色超声所获得的形态学和血流动力学信息,对移植肾排斥反应具有很重要的临床价值。
Objective We aimed to improved the ultrasonographic.3h bvudiagnosis rate of rejection of transplant kidneys. Methods [WTBZ]Pathology of kidney biopsy and ultrasonographic features of 23 cases with transplant kidneys were retrospectively reviewed and analyzed. Results Three types rejection of transplant kidney had their own sonographic characteristics. HAR(hyperacute rejection):2-dimensional ultrasonographic changes: Increase of transplant renal volume, weakening of cortical echo, CDFI:RI(resistant index)≥ 0.85. AR(acute rejection):2-DUS: obvious increase of renal volume, more distinct lowering of cortical echo,CDFI: RI >0.75. CR: decrease of renal volume, strengthen of cortical echo, CDFI: RI:0.67-0.8. Conclusions The morphological and hemodynamic information obtained by 2-DUS and CDFI were significantly valuable to diagnose rejection of transplant kidneys.
