The age influence the kidney stiffness assessed by means of Acoustic Radiation Force Impulse (ARFI) elastography?

ARFI elastography is very useful for liver stiffness assessment, but few information are available regarding kidney stiffness (KS), especially in non-transplanted kidney. Purpose: To establish the influence of age on KS values in “normal” subjects. Methods: Our study included 83 “normal” subjects: 33 healthy volunteers (39.8%) without known kidney pathology with normal renal ultrasonography, without history of renal disease (supplementary investigations were not performed in these subjects) and 50 patients hospitalized (60.2%) for various diseases with normal renal ultrasonography, normal serum creatinine and bl…
