| Purpose: The purpose of this study is to assess the usefulness of Doppler parameters
in transplanted kidney function.
Materials and Methods: Doppler parameters, including resistive index (RI), pulsatility
index (PI), peak systolic velocity (PSV), and end diastolic velocity (EDV) were
measured in the interlobar artery of 55 transplant recipients. Patients were grouped
according to glomerular filtration rate (GFR): Group A (GFR < 30 ml / min / 1.73 m2, n
= 27) and group B (GFR ≥30 ml / min / 1.73 m2, n = 28). Doppler parameters were
compared between groups and correlated with the GFR.
Results: GFR (40.1± 26.9) showed a significant negative correlation with RI (0.69±.08) (p = .002, r = -.414). RI (0.72 vs. 0.67), PI (1.42 vs. 1.23), and EDV (10.5 vs.
15.3) differed significantly between groups (p < .05), however, PSV was not (36.9 vs.
47.1). Patients in group A (n = 11) with a lower RI than the mean had significantly
lower PSV (31.7 vs. 45.1; p = .027) and EDV (11.1 vs. 16.7; p = .017), compared with
such patients in group B (n = 21).
Conclusions: Doppler parameters are useful for evaluation of function of transplanted
kidney. Even if the RI is normal, PSV and EDV may be used as hemodynamic
indicators. |
