The Approach to the Patient with Hematuria.

Hematuria is common; whether gross or microscopic, it is incumbent on emergency providers to consider life-threatening and benign processes when evaluating these patients. Most workup is driven by a focused history and physical, including laboratory studies and diagnostic imaging. The cause originates in the genitourinary tract and, as long as the patient remains stable, they can be discharged with close outpatient follow-up. The importance of this cannot be stressed enough because hematuria, especially in the elderly, frequently signals the presence of urologic malignancy. In addition, the workup occasionally yields a nongenitourinary tract cause, and these patients often require emergent management.
