移植肾术后急性排斥反应患者肾动脉阻力指数与血肌酐的相关性研究

Correlation between renal artery resistance index and serum creatinine in acute rejection of renal transplant

目的探讨移植肾术后急性排斥反应患者肾内各级动脉阻力指数(RI)与血肌酐(Cr)的相互关系及临床应用价值。方法对32例移植肾术后出现急性排斥反应患者分别于术后1、3、5、7、9 d(T_1、T_3、T_5、T_7、T_9)采用彩色多普勒超声检查,检测肾内各级动脉阻力指数,同期测定血肌酐值,分析两者之间的相关性。结果移植肾急性排斥反应时肾内各级动脉血流阻力指数与血肌酐呈线性正相关(P<0.05),差异有统计学意义。结论移植肾急性排斥反应时,肾内各级动脉血流阻力指数与血肌酐有明显相关性,且肾内各级动脉血流阻力指数升高早于血肌酐,RI在移植肾急性排斥反应早期具有重要的临床意义。

Objective To correlate renal artery resistance indices （RI） and serum creatinine in patients with acute rejection after renal transplantation. Methods Color Doppler ultrasound was performed on 32 patients with acute rejection at 1, 3, 5, 7, 9 days （T1, T3, T5, T7, T9） after renal transplantation. The renal artery RI were measured and correlated with serum creatinine obtained simultaneously. Results Renal artery RI rise earlier than serum creatinine. There was significant positive correlation （P 〈 0.05） between the renal artery RI and serum creatinine. Conclusions Renal artery RI correlate well with serum creatinine and can aid detection of early acute rejection after renal transplantation.
