[Hematuria: which algorithm for an effective diagnostic strategy?]. / Hématurie: quel algorithme pour une stratégie diagnostique efficace?

Microscopic hematuria is common in medical practice; its prevalence in the adult population varies between 2.5 and 13%. Currently available data are insufficient to determine an algorithm based on evidence of the most effective diagnostic strategy of hematuria. Avoid invasive tests for the patient and expensive for the community, determine whether the hematuria of glomerular origin or not, facilitate the clinician referral to a nephrologist or urologist for the etiological diagnosis, should be the basic principles of any approach to develop such an algorithm. We try to answer on this question in this article.
