Role of Renal Artery Doppler Ultrasonography in the Evaluation of Function of Transplanted Kidney
摘要
Abstract
Objective:To evaluate the clinical value of renal artery Doppler ultrasonography in the diagnosis of renal transplant dysfunction by detecting blood perfusion in transplanted kidney with ultrasound .Methods:A total of 107 renal transplantation patients ,aged (38 .8 ± 1 .6) years in average ,including 68 new cases and 39 follow‐ups ,were recruited .Peak systolic velocity (PSV) ,end‐diastolic velocity (EDV) and resistance index (RI) ,in main renal artery ,renal segmental arteries and interlobar arteries of transplanted kidneys ,were examined by color Doppler ultrasonography .Results:Hemorheologic alterations in renal segmental arteries and interlobar arteries were closely correlated with renal function .Correlation indexes between PSV and clearance of creatinine (Ccr) were r=0 .072(P>0 .05) ,r=0 .224 (P=0 .014) and r=0 .250 (P=0 .006) ,respectively ,in main renal artery ,renal segmental arteries and interlobar arteries .Correlation indexes between RI and Ccr were r= -0 .398 (P<0 .001) ,r= -0 .400(P<0 .001) and r= -0 .436(P<0 .001) ,respectively ,in main renal artery ,renal segmental arteries and interlobar arteries .Correlation indexes between EDV and Ccr were r=0 .446(P<0 .001) ,r=0 .659(P<0 .001) and r=0 .529(P< 0 .001) ,respectively ,in main renal artery ,renal segmental arteries and interlobar arteries .The above results indicated that ,the maintenance of diastolic blood flow in renal arteries was important for renal function .The increase of RI and decrease of EDV in arteries of transplanted kidney was characteristic manifestation of chronic allograft nephropathy and vasculitic rejection .Conclusions:Renal artery Doppler ultrasonography can effectively measure the hemorheologic alterations of transplanted kidney ,thus it is an important adjuvant diagnostic tool for clinical renal transplantation .关键词
