AIMS: The kidney becomes @entity740 , and renal size and parenchymal volume correlate with renal function. However, alterations in renal parenchymal volume have not been adequately studied in terms of the renal cortex and medulla. We investigated the relationship between the changes in the renal cortex and medulla and renal function. METHODS: Renal ultrasound (US) parameters including @entity8 , parenchymal @entity121 , @entity121 and medullary @entity121 were assessed in 176 subjects, who were categorized into 4 groups based on the estimated glomerular filtration rate (ml/min/1.73 m2): group 1, >= 90; group 2, >= 60 but <90; group 3, >= 30 but <60; and group 4, <30. Renal US parameters in both kidneys were compared among the 4 groups. RESULTS: We found stepwise associations in @entity8 , @entity121 and parenchymal @entity121 with @entity177 . Medullary @entity121 showed no changes among groups 1-3. Multiple linear regression analysis including sex, age and renal US parameters showed that only @entity8 was an independent predictor of renal function. When analyzed in groups 1-3, @entity121 was the strongest associated parameter. Lower cortical left/right ratio (left @entity121 /right @entity121 ) showed a stepwise association with a decrease in renal function. CONCLUSION: Renal length and @entity121 measured by US were correlated with renal function. In particular, left @entity121 could help to detect early changes in renal function.
