What does heterogeneous erythrocyturia mean?

Hematuria is a term used to distinguish between hematuria of renal origin, medical origin, or surgical origin, such as hematuria caused by stones or tumors. Renal hematuria, for example, has a high fragmentation rate due to glomerular destruction of red blood cells, resulting in a loss of homogeneity, and thus appears as heterogeneous hematuria. If it shows heterogeneous red blood cell urine, it often indicates the source of renal hematuria, and further examination is needed for glomerulonephritis, acute nephritis and other diseases. If hematuria formed by stones, tumors, etc., red blood cells are relatively complete and less destroyed, so the examination belongs to homogeneous red blood cell urine, which often indicates surgical hematuria. Further B-ultrasound and CT examinations are needed to check whether there are stones, tumors, infections and other diseases in the urinary tract. Erythrocyte phase is a simple method to distinguish medical hematuria from surgical hematuria.
