Objective To investigate the clinical application value of Hilson perfusion index(PI) in patients with kidney disease.

Methods The PI value and glomerular filtration rate(GFR) of 20 normal people and 80 patients with kidney disease were measured.

Results The normal PI values for the left and right kidneys were 147.2±41.14 and 155.25±41.73, respectively, whereas the PI values for chronic renal failure, stenosis of renal artery, nephrotic syndrome, hydronephrosis, and renal calculus for the left and right kidneys were 459.28±68.15, 476.67±38.99; 436.14±61.88, 420.85±66.39; 379.40±111.00, 372.20±99.52; 333.75±140.94, 321.08±132.43; and 267.75±149.93, 283.37±142.63, respectively. Moreover, the PI values for mild, moderate, and severe renal impairment of the left and right kidneys were 328.62±41.21, 335.14±39.85; 412.27±53.81, 427.86±61.12; and 466.81±110.64, 471.64±112.96, respectively, which were higher than those in the normal control group. The PI results were negatively correlated with GFR, and the correlation coefficient(r) was 0.741.

Conclusion Hilson perfusion index exhibited high clinical value.
