摘要
目的：为了解肝硬化病人肾脏血流动力学的变化，并探讨其与肾功能的关系。方法：应用彩色多普勒检测２５例肝硬化病人和１５例正常人的肾动脉血流动力学改变，测定其血清肌酐、尿素氮和血浆醛固酮水平。结果：肝硬化病人与正常人比较，肾动脉内径变窄、阻力指数增大、肾血流量降低（Ｐ＜０．０５），血浆醛固酮明显升高，而血清肌酐、尿素氮水平仍在正常范围。结论：多普勒超声定量监测肝硬化病人肾动脉血流动力学变化，有助于早期发现肾功能损害。
Aims:In order to investigate the renal hemodynamics with liver cirrhosis,and discuss the relationship with renal functions.Methods:Renal arterial hemodynamics were evaluated in 25 cirrhotic patients and 15 volunteers by doppler ultrasound,and the levels of serum creatinine urea nitrogen and plasma aldosterone were determined.Results:Comparing with controls,it showed that the diameter of renal artery and renal blood flow in cirrhotic patients were significantly decreased,resistive index (RI) and plasma aldosterone in cirrhotic patients were significantly increased,but levels of serum creatinine and urea nitrogen were still in normal ranges.Conclusions:The alterations of renal arterial hemodynamics in cirrhotic patients were determined quantitively by doppler ultrasound,and impairment of renal function could be found earlierly.
