[Hematuria--diagnostic procedure and therapeutic approaches].

Hematuria is a common clinical problem. It may arise from benign diseases posing minimal risk to the patient to potentially life-threatening conditions. Due to its many causes, the evaluation of hematuria often requires various different diagnostic procedures. To prevent unnecessary diagnostic tests, the workup should begin with noninvasive techniques such as history, urinalysis, laboratory data and ultrasonography. This proceeding allows a simple and rapid differentiation in renal and non-renal causes of hematuria in most cases.
