The powerful urinary procoagulant and its relation to renal diseases.
Human urine and urine of various animals contains a powerful procoagulant which converts prothrombin in presence of factors V, VII, X, and phospholipids or thrombocytes into thrombin. In human beings its content of the urine is markedly reduced or totally absent in kidney diseases, but normal in hemophilic patients. Only 0.2 ml urine are required for its assessment. In experimental kidney diseases in rabbits and rats there is an inverse relationship between procoagulant and protein excretion. In the test tube 1 part of urine corrects the clotting of 5-10 parts of hemophilic plasma, even in the presence of very strong coagulation inhibitors.
