Abstract:
Objective To compare blood flow perfusion conditions of renal allograft of different renal function with conventional ultrasound and contrast enhanced ultrasonography (CEUS). Methods Sixty patients underwent kidney transplatation were divided into normal group (SCr≤110 μmol/L) and abnormal group (SCr＞110 μmol/L). Renal structure and inner diameter of renal artery were messured with two-dimensional ultrasound. The hemodynamic parameters (PSV, EDV and RI) were messured with CDFI. Data of renal blood flow perfusion (AT, TTP, △I and Increase), data of renal blood flow perfusion (AT, TTP, △I and Increase) were quantitatively analyzed with CEUS combined with time intensity curve. All the data were compared between two groups.Results There was no significantly difference of above indexes for B-mode ultrasound and CDFI between two groups, except EDV of arcuate arteries. CEUS parameters of patients with normal renal function were better than those with abnormal function.Conclusion Microcirculation perfusion changes of transplanted kidney with abnormal function could be detected with CEUS. The quantitative indexes of transplanted kidney with normal function were better than those with abnormal function.
