HAEMATURIA-CAUSES

1. Determine if hematuria is due to intrinsic renal disease or genitourinary bleeding.

GLOMERULAR BLEEDING
2. Hematuria associated with proteinuria, especially if dys­morphic cells and/or RBC casts are present in the urine, is always due to glomerular bleeding.

3. The most common causes of isolated glomerular hematuria (normal renal function, no proteinuria) are IgA nephropathy, thin basement membrane disease, and early Alport syn­drome.

MICROSCOPIC/MACROSCOPIC, NON-GLOMERULAR BLEEDING
4. Isolated microscopic or gross hematuria is more likely to be urologic in origin.

5. Strenuous exercise can cause transient hematuria.

6. Patients with sickle cell trait may also have hematuria.
