摘要
目的观察亲属移植肾叶间动脉的阻力指数(RI)、搏动指数(PI)与血清胱抑素C(SCysC)变化的相关性。方法对我院的60例亲属肾移植病例(受者和供者各30例)行术前、术后超声和实验室肾功能检测,重点观察供者术前1周、受者术后1周、1个月、3个月及6个月内的血流动力学及肾功能变化及其相关关系。结果ScysC、血清肌酐(Scr)术后1周较供肾显著升高(P<0.01),术后6个月内随肾功能的恢复逐渐下降,但仍高于供肾水平。叶间动脉的RI、PI术后1个月内较供肾升高。RI、PI与ScysC、Scr的变化呈正相关。RI、PI与ScysC相关性较RI、PI与Scr更佳(P<0.05)。结论移植肾叶间动脉RI、PI联合ScysC检测能更及时、精确、便捷的反应移植肾者肾脏功能。
Objective To assess the association of resistance index（RI）,pulsatility index（PI）of interlobar artery with serum cystatin C（SCysC）in relative renal transplantation.Methods Color Doppler ultroson0graphic findings and renal function parameters in 60 relative kidney transplanted recipients and donors were evaluated.Color Doppler uhrosonography was performed on the donor kidney at 1 week before and on the transplanted kidney at 1 week to 6 months after kidney transplantation.In the same time,SCys C and serum creatinine（Scr）were measured,respectively.Results One week after surgery, ScysC and Scr were significantly higher in transplanted kidney than that in the donor kidney（P〈0.01）.One month after surgery,RI,PI,ScysC and Scr increased in transplanted kidney（P〈0.05）,and there was significant correlation between RI and PI of interlobar artery and SCys C.RI,PI of interlobar artery correlated with Scr,the correlations of RI and PI with SCys C was better than the correlations of RI and PI with Scr（P〈0.05）.Conclusion The correlation of RI and PI with Cyst C is better than that of RI and PI with Scr.RI and PI of interlobar artery are good markers for early time detecting the renal function.
