[Role of color flow mapping ultrasonography in kidney transplant monitoring]

Abstract

Color flow mapping and duplex ultrasonography are a more accurate technique in renal allograft monitoring by combining real time us with pulsed doppler studies of renal vasculature. Doppler spectral analysis, pulsatility and resistive index evaluation are usefull in the diagnosis of renal allograft dysfunction (I.E. rejection, cyclosporine nefroto-city and acute tubular necrosis). Cfm and duplex ultrasonography allow a non invasive and easy evaluation of the whole renal artery and vein in the diagnosis of renal artery stenosis, vein trombosys and A-V fistula.
