Clinical value of Doppler ultrasound in the first two months after kidney transplant.
The ability of PI measurements to differentiate between acute rejection and ATN was investigated in 37 patients, who were frequently examined by duplex Doppler after kidney transplant. Absolute PI values as well as increase in PI were recorded and the clinical course was correlated with these pulsatility measurements. PI values were evaluated in 70% of patients undergoing acute rejection. However, in the majority of patients with ATN, the PI was evaluated from the start and continued to rise to an average of 8 days post-transplant. This rise in PI in patients with ATN suggests that pulsatility measurements are unreliable tests to differentiate acute rejection from ATN in the early post-transplant period.
