Abstract:
Objective To explore the clinical value of 99mTc-diethylenetriaminepentaacetic acid(DTPA)renal dynamic imaging in evaluating renal tubulointerstitial injury in early adult primary nephrotic syndrome(PNS)patients.Methods A total of 42 early adult PNS patients were selected as case group,and the diagnostic efficacy of 99mTc-DTPA renal dynamic imaging quantitative indicators and biochemical indicators of serum creatinine(SCr),blood urea nitrogen(BUN),blood uric acid(UA),blood retinol-binding protein(RBP),and blood β2-microglobulin(β2-MG)levels in renal tubulointerstitial injury was analyzed based on pathological results with or without renal interstitial injury as the standard.Results ①The total glomerular filtration rate(GFR),left kidney GFR and right kidney GFR were negatively correlated with blood SCr,BUN and β2-MG levels of patients in case group.②The diagnostic efficiency of total GFR in diagnosis of tubulointerstitial injury in early adult PNS patients is better than that of blood SCr,BUN and β2-MG,total GFR combined with time to peak(Tp),half discharge time(T1/2)and 20 minute residual rate(R20/p)can improve the diagnostic efficiency.Conclusion 99mTc-DTPA renal dynamic imaging is helpful in early diagnosis of tubulointerstitial injury in early adult PNS patients.
