Shear wave elastography and Doppler ultrasound in kidney transplant recipients

OBJECTIVE: To evaluate the association between shear wave elastography parameters and arterial resistance in kidney transplant recipients. MATERIALS AND METHODS: This was a prospective cross-sectional study involving consecutive adult kidney transplant recipients. All patients underwent color Dopple...

description OBJECTIVE: To evaluate the association between shear wave elastography parameters and arterial resistance in kidney transplant recipients. MATERIALS AND METHODS: This was a prospective cross-sectional study involving consecutive adult kidney transplant recipients. All patients underwent color Doppler to evaluate the resistive index (RI) and ultrasound shear wave elastography for the quantification of renal allograft stiffness. RESULTS: We evaluated 55 patients, of whom 9 (16.4%) had an RI defined as abnormal (≥ 0.79) and 46 (83.6%) had an RI defined as normal (< 0.79). The mean age was higher in the abnormal RI group than in the normal RI group (68.0 ± 8.6 years vs. 42.6 ± 14.1 years; p < 0.001), as was the mean shear wave velocity (2.6 ± 0.4 m/s vs. 2.2 ± 0.4 m/s; p = 0.013). Multivariate analysis identified two independent predictors of arterial resistance: age (OR = 1.169; 95% CI: 1.056 to 1.294; p = 0.003) and shear wave velocity (OR = 17.1; 95% CI: 1.137 to 257.83; p = 0.040). CONCLUSION: We observed an association between rigidity in the cortex of the transplanted kidney, as evaluated by shear wave elastography, and arterial resistance, as evaluated by color Doppler, in kidney transplant recipients.
