超声造影和二维超声参数对移植肾术后并发症的鉴别应用价值
Application value of contrast-enhanced ultrasound and two-dimensional ultrasound parameters of complications after renal transplantation
摘要
Abstract
Objective To investigate the value of 5 parameters of contrast-enhanced ultrasound and two-dimensional ultrasound in the diagnosis of renal transplantation dysfunction by using external perfusion software VueBox.Methods A total of 87 patients with abnormal kidney transplantation in the kidney trans-plantation department of our hospital and those in other hospitals who were older than 18 years old and under-went ultrasound examination and contrast-enhanced ultrasound(CEUS)after kidney transplantation were se-lected as the study objects from July 2023 to February 2024.Among them,8 cases of renal artery obstruction and 6 cases of severe perirenal hydronephrosis were excluded,and a total of 73 cases were included.The pa-tients were divided into acute rejection(AR)group(18 cases),delayed renal function recovery(DGF)group(8 cases)and stable renal function group(47 cases)according to the postoperative renal function recovery and pathological examination results.Compare and analyze the difference of quantitative analysis parameters of CEUS in 3 groups,including cortical peak time(TTP),medullary TTP,aorta ascending time(RT),aorta de-scending time(FT),aorta TTP,etc.Results The renal artery blood flow resistance index,cortical TTP,me-dullary TTP,main renal artery RT,main renal artery TTP,and main renal artery FT were compared among the three groups of patients,and the differences were statistically significant(P＜0.05).The TTP of cortical and medullary regions of interest(ROI),as well as the TTP,RT,and FT of the main renal artery ROI in the DGF group were longer than those in the AR group.The accuracy of VueBox quantitative analysis parameters in differential diagnosis of AR and DGF was from high to low in order of main renal artery TTP,main renal artery RT,main renal artery FT,medullary TTP,cortical TTP.The area under the subject operating charac-teristic curve of TTP and RT were large,the sensitivity were 87.5％,87.5％,the specificity were 81.2％,87.5％.Conclusion There are significant differences in the VueBox quantitative analysis parameters of AR and DGF after renal transplantation,which can provide imaging references for the diagnosis of AR and dys-function after renal transplantation.关键词
