Frequency and Etiology of Gross Hematuria in a General Pediatric Setting

Abstract

Since the frequency of gross hematuria in general, unselected, pediatric outpatient settings has not been reported, we reviewed all patients with this symptom or sign at a pediatric emergency walk-in clinic during 24 consecutive months. Of a total of 128,395 patient visits, gross hematuria was proven in 158 (1.3/1,000 visits). Fifty-six percent of all patients had readily apparent causes for their gross hematuria. Twenty-six percent of all hematuric patients had documented urinary tract infections, but only 9% had apparent glomerular disease.
