About 0.25% of school-age children have persistent microscopic hematuria. In adults the prevalence of hematuria increases with age and is greater in women. The causes and consequently the workup of hematuria vary with age. Glomerular disorders are responsible for most cases of pediatric hematuria, while urinary tract malignancy is an important cause of hematuria in individuals over 40 years of age.
