Use of a bleeding time determination in the evaluation of unexplained hematuria
Although von Willebrand's disease is an unusual cause of gross hematuria in children, it is readily treatable with fresh frozen plasma or cryoprecipitate. We present 2 cases of recurrent, painless gross hematuria owing to this congenital factor VIII deficiency disorder. In each case the diagnosis was suggested first by the finding of a prolonged bleeding time. We suggest that the bleeding time determination be included as part of the screening hemostatic studies used in the evaluation of unexplained hematuria.
