[Duplex-Doppler sonography in the diagnosis of acute rejection in kidney transplantation].

Duplex Doppler sonography can be used in evaluation of renal allografts. Arterial Doppler signals were quantified with a pulsatility index. In this study 114 Duplex Doppler examinations were performed in 75 patients after renal transplantation. The mean PI in patients with acute rejection was statistically compared with the mean PI in normal allografts, and the mean PI in patients with CsA nephrotoxic effects and chronic rejection. The data shaw that there is statistically significant difference between the patients with acute rejection and other examined groups. The results of this study show that the use of quantitative Doppler US scanning may be valuable in differential diagnosis among the various forms of graft disfunction.
