摘要
目的：探讨超声造影定量分析在诊断代偿期慢性肾功能衰竭的价值。方法：对我院45例慢性肾功能衰竭患者行超声造影检查、频谱多普勒检查、生化检查。结果：超声造影发现造影剂到达时间（AT）、达峰时间（TTP）、达峰强度（PI）在正常对照组、慢性肾功能衰竭代偿期组和慢性肾功能衰竭失代偿期组这3组组间均差异显著（P<0.05），且AT、TTP依次延长，PI依次降低。频谱多普勒发现肾脏血流在肾功能代偿期普遍呈高速低阻频谱，在肾功能失代偿期普遍呈低速高阻频谱，且段动脉的灵敏度低于叶间动脉和弓形动脉。血肌酐（Scr）、尿素氮（BUN）在正常对照组与肾功能失代偿组间、肾功能代偿组与肾功能失代偿组间差异显著（P<0.05），且Scr、BUN升高。结论：超声造影更有利于评估代偿期慢性肾功能衰竭的肾功能情况。
Abstract
Objective: To discuss the value of contrast-enhanced ultrasound(CEUS) in evaluating renal function in patients with compensated chronic renal failure. Methods: Forty-five patients with chronic renal failure were examined by CEUS and color Doppler flow imaging(CDFI). The study also included examination of blood biochemistry. Result: CEUS showed arriving time(AT), time to peak(TTP) and peak intensity(PI) was significantly different in all groups(P<0.05). With increasing renal function failure, AT and TTP delayed, and PI decreased. During the compensatory phase of renal function, the renal blood flow showed high velocity and low resistence index. At the decompensatory stage, the renal blood flow showed slow velocity and high resistence index. Those appearances were more significantly between interlobar artery and arcuate artery than major renal artery. Serum creatinine(Scr) and serum urea nitrogen(BUN) of the decompensatory group were more significantly different compared with the other two groups(P<0.05), and showed higher. Conclusion: CEUS is more helpful in evaluating renal function of the compensatory chronic renal failure.
