Color Doppler Ultrasound in the Diagnosis of Acute Rejection after Allogeneic Renal Transplantation

摘要

The aim of the study was to investigate the role of ultrasound in the diagnosis of acute rejection after allogeneic renal transplantation. Thirty-two renal transplant patients with acute rejection were enrolled in the rejection group, and 32 kidney transplant patients with no acute rejection matched with ageing, gender, and weight were selected to form a non-rejection group for comparative study. Finally, we found Renal volume, cortical echo, resistance index (RI), and end-diastolic velocity (EDV) were significantly different between groups (P<0.05). There was a significant difference in cortical thickness, resistance index, and perfusion flow between the patients with acute rejection and those with no significant improvement after symptomatic treatment (P<0.05). So, Color Doppler ultrasound has a high accuracy in the diagnosis of acute rejection after allogeneic renal transplantation, especially for the evaluation of the effect of acute rejection therapy.
