title: Hematuria due to urolithiasis in a child with chronic immune thrombocytopenic purpura.
abstract: Hematuria is an uncommon manifestation of chronic immune thrombocytopenic purpura. The occurrence of urolithiasis in children with chronic immune thrombocytopenic purpura has not been described. We report a case of hematuria due to urolithiasis in an 8-year-old boy with chronic immune thrombocytopenic purpura. This child, who had a history of immune thrombocytopenic purpura of 1 year's duration, presented to the emergency department with gross hematuria. The cause of hematuria was initially attributed to his primary disease process. A careful history, examination, and pertinent investigations revealed that the hematuria was secondary to urolithiasis. This report highlights the need to keep an open mind and to search for specific causes of bleeding, even in children with known bleeding disorders.
