Correlation of total cholesterol and protein in urine in patients with the nephrotic syndrome.

The excretion of protein and cholesterol in 24 h urine was measured in 42 patients with the nephrotic syndrome. The finding of a positive correlation (r = 0.76, p < 0.01) between urinary cholesterol and urinary protein would be compatible with an enhanced glomerular filtration of plasma lipoproteins as the cause of lipiduria in the nephrotic syndrome.
