Hematuria

GENERAL PRINCIPLES

Hematuria, or blood in the urine, is common in the outpatient setting.

Concomitant findings, such as pain, renal injury, and proteinuria, help to localize the site of injury along the genitourinary tract.

Persistent hematuria may be a sign of serious disease and should not be ignored.

Definition

Hematuria is the presence of red blood cells (RBCs) in urine.

Gross hematuria is visible to the naked eye and often manifests as red, pink, or cola-colored urine.

Microscopic hematuria is defined by the American Urological Association (AUA) as the presence of ≥3 RBCs/high-power field (HPF) on microscopic examination of one properly collected, noncontaminated urinalysis in the absence of obvious benign cause.1

Microscopic hematuria should be confirmed on two out of three midstream clean-catch urine samples before proceeding with further workup.
