Diagnosis and Treatment of Hematuria

Hematuria is a common manifestation caused by various factors such as infection, inflammation, trauma, urinary stone and malignancy. Hematuria reflects pathological state of urinary system. Isolated microscopic hematuria without any abnormalities besides of hematuria on urine microscopic examination usually presents a good clinical course or outcome. However, significant proteinuria or hypertension, which accelerates renal dysfunction, can often develop during follow-up period in patients with isolated microscopic hematuria. Compared with non-glomerular hematuria, glomerular hematuria shows several characteristic findings such as dysmorphic red blood cell (RBC) or RBC casts or significant proteinuria on urinalysis. If glomerular hematuria is strongly suspected, a kidney biopsy may be required to differentiate the cause of glomerulonephritis. In this review, we tried to review the differential diagnosis and diagnostic approach and treatment of hematuria.
