Hyperuricemia has been reported to affect renal hemodynamics. In a recent study, both low and high levels of serum uric acid (SUA) were found to be associated with loss of kidney function. The goal of this study was to evaluate the relationship between SUA levels and intrarenal hemodynamic parameters in healthy subjects, using plasma clearance of para-aminohippurate (C PAH ) and inulin (C in ). Renal and glomerular hemodynamics were evaluated by simultaneous measurements of C PAH  and C in  in 48 healthy subjects (54.6 ± 13.4 yr). Intrarenal hemodynamic parameters, including efferent and afferent (R a ) arteriolar resistance, were calculated using Gómez’s formulas. Relationships of SUA levels with these intrarenal hemodynamic parameters were examined. In quadratic regression analysis, SUA levels had a significant inverse U-shaped relationship with C in  ( P  6.0 mg/dl) SUA levels entered as dummy variables of zero and one, respectively, mildly low or high SUA levels were significantly and independently associated with R a  (β = 0.230, P = 0.0403) after adjustment for several factors ( R 2  = 0.597, P &lt; 0.0001). Both mild hyperuricemia and mild hypouricemia are significantly associated with increased R a , although weakly. The increase in R a  in subjects with mild hyperuricemia or hypouricemia may be related to renal hemodynamic abnormalities, possibly leading to a decline in renal function.
