摘要
目的：探讨超声弹性成像5分法及定量分析技术对慢性移植肾肾病（CAN）的诊断价值。方法：筛选接受同种异体肾移植手术患者46例，其中移植肾肾功能稳定者26例归为稳定组，发生CAN且出现肾功能不全患者20例归为CAN组，使用超声弹性成像5分法、弹性成像应变率比值测定及弥散定量分析技术分析组间差异。结果：CAN组UE声像图表现为：锥体及肾柱部分大部分呈绿色并点状蓝色镶嵌，皮质呈大部蓝色或全部蓝色；稳定组UE声像图表现为：椎体及皮质可见均匀分布的绿色，肾周脂肪及弓形动脉呈带状红色。5分法评分结果显示稳定组患者评分均在2分或2分以下，CAN组评分均在2分以上，其中3分及3分以上占80%；CAN组髓质与皮质B/A比值、皮质AREA%大于稳定组，MEAN值小于稳定组。结论：UE定量分析技术可用于CAN的诊断，有望为临床移植肾术后监测肾功能提供一种新的、无创的、便捷的影像学方法。
Abstract
Objective: To investigate the value of ultrasonic elastography(UE) 5 scores method, strain ratio determination and quantitative analysis in the diagnosis of chronic allograft nephropathy(CAN) after transplantation. Methods: Forty-six patients with renal transplantation were included in the study, including 26 patients with stable renal function(SF group) and 20 patients with chronic allograft nephropathy and renal insufficiency(CAN group). UE 5 scores method, strain rate ratio determination and quantitative analysis were used to analyze differences in and between groups. Result: UE sonography in the CAN group showed almost all green with spotty blue in renal column and pyramid, while the cortex was most or totally blue. UE sonography in the SF group showed green in pyramid and cortex evenly and red in perirenal fat and arcuate arteries. UE 5 scores method showed that all were below 2 scores in SF group, but all were above 2 scores in CAN group, of whom eighty percent(16/20) were equal to or above 3 scores(including 3 scores). There were significant differences in B/A, mean and AREA% between SF and CAN group. Conclusion: UE quantitative analysis techniques can be used for the diagnosis of CAN. It should be a new, non-invasive and convenient imaging method for monitoring renal function.
