Abstract:
Objective To explore the value of color Doppler ultrasound detection renal interlobar arterial hemodynamic parameters for early diagnosis in patients with chronic kidney disease(CKD).MethodsSeventy-eight patients with CKD were undergone interlobar arterial hemodynamic parameters detection and 65 normal persons served as the control.The peak systolic velocity (PSV),end-diastolic velocity (EDV),pulsatility index(PI),resistive index (RI) of interlobar arterial and serum cystatin C (SCysC) were measured.The variation of RI and the correlation of renal interlobar arterial RI and pathological findings in early CKD was analyzed.Results In 40 CKD cases with normal SCysC(group A),the PSV,EDV,PI,RI of renal interlobar arterial were not statistically significant (P>0.05).In 38 CKD cases with increased SCysC(group B),the RI of renal interlobar arterial were higher than those of group A and control group (P<0.05),and the PSV and EDV were lower than those of group A and control group (P<0.05).In cases of CKD with normal RI,the disease limited to the glomeruli;while the RI increased,the disease locate in the tubulointerstitial compartment.Conclusions Interlobar arterial RI united SCysC is a sensitive indicator in assessing early injury of chronic kidney disease.
