| 摘 要： | 目的 分析移植肾急性排异反应不同时期的血流动力学特征。方法 对31例肾移植术后发生急性排异反应病人不同时期多普勒超声检查资料作回顾分析。结果 在血肌酐升高前24h内，多普勒参数阻力指数(RI)和搏动指数(PI)增高的为19例。急性排异反应中，多普勒参数RI和PI与血肌酐有一定的相关性；在急性排异反应治愈过程中，多普勒参数RI和PI的恢复与血肌酐的恢复并不同步。结论 彩色多普勒观察移植肾有一定的临床意义，但要注意观察时机。

Doppler Ultrasongraphic Examination in Acute Renal Transplant Rejection |

| Abstract: | Objective To study the hemodynamic characteristics during different periods of a-cute renal transplant rejection. Methods Doppler ultrasound findings of 31 patients with acute rejec-tion after kindney transplantation were retrospectively analyzed. Results In 24h before serum creati-nine rised, pulsatity index (PI) and resistive index (RI) increased in 19 eases. PI and RI were certain toa extent were correlated with serum creatinine in crease during acute rejection. Analysis of 31 rejectionepisodes showed no concurrent Doppler and serum creatinine comebakes. Conclusion Doppler ultra-sound examination at the optimun time is an effective method to detect acute renal transplant rejection. |
