Hematuria: Updates in Management and Considerations for the Obstetrician/Gynecologist

is defined as the presence of red blood cells (RBCs) in the urine. Clinically, it is classified as either mac-roscopic (gross) or microscopic. With gross hematuria, urine is visibly discolored by blood. Microscopic hematuria is often identified incidentally when urine is being evaluated for another indication. Multiple definitions of microscopic hematuria have existed over the years. The standard definition of microscopic hematuria, established by the American Urological Association (AUA), is 3 or more per high-powered field (HPF) on microscopic evaluation of a single, properly collected urine specimen in patients without another apparent benign cause of the blood.
