Answer

The prevalence of gross hematuria in children is estimated to be 0.13%. In more than half of the cases (56%) this is due to an easily identifiable cause. The most common cause appears to be cystitis (20-25%). Asymptomatic microscopic hematuria is, on the average, 10-fold as prevalent as gross hematuria (1.5%, range 0.4-4.1%, depending on the criteria used to define hematuria). With repeated evaluations, the prevalence of asymptomatic microscopic hematuria decreases to less than 0.5%, supporting the notion that most cases of hematuria in children are transient. The incidence of simultaneous hematuria and proteinuria is estimated to be only 0.06%, but their coexistence signals significant renal disease.
