To elucidate the origin of the fibrin/fibrinogen degradation products (F.D.P.) occurring in the urine in glomerulonephritis 28 patients with glomerulonephritis were examined for renal fibrinolytic activity, F.D.P. in urine and serum, and blood fibrinolytic activators and blood fibrinolytic activators and inhibitors. Unlike the glomerful of healthy kidneys, which were fibrinolyticly inactive, those of kidneys with glomerulonephritis constantly showed fibrinolytic activity. The presence or absence of fibrin in the glomeruli was almost always accompanied by, respectively, the presence or absence of urinary F.D.P., which suggested a renal origin of urinary F.D.P. in glomerulonephritis. The low fibrinolytic activity of the blood and the absence of F.D.P. in the serum of these patients make it unlikely that the urinary F.D.P. in glomerulonephritis result from glomerular filtration.
