A. Akdilli et al., The diagnostic value of intrarenal colour duplex Doppler ultrasonography in children with lower urinary tract infection, PEDIAT RAD, 29(12), 1999, pp. 897-900
Background. The diagnostic value of Doppler US in infectious disease of the
kidney is well documented. Previous studies have demonstrated high resisti
ve indices, especially in tubulo-interstitial diseases.
Objective. To evaluate the role of intrarenal colour duplex Doppler US in l
ower urinary tract infections (UTI).
Materials and methods. This prospective study was carried out in 111 childr
en (222 kidneys) (age range 1-180 months). Of the children, 78 were healthy
while 33 presented with lower UTI. The resistive indices (RI) were measure
d from the spectral waveforms obtained from interlobar arteries.
Results. No statistically significant difference was found between RI of ri
ght and left kidneys in both groups. The mean RI was 0.75 +/- 0.07 in patie
nts with lower UTI and 0.71 +/- 0.1 in the control group (P < 0.05). In the
control group there was an inverse correlation between age and RI (P < 0.0
5).
Conclusions. High RI may be found in lower UTI.
