[Appropriateness of complementary exams in the initial assessment of acute kidney injury]

Current protocols recommend an initial assessment of acute kidney injury often extensive, not very useful in the majority of cases. A review of the literature allowed us to propose a management algorithm limiting these investigations integrating a « less is more » approach. The cornerstone of this algorithm is the urinary dipstick, inexpensive and easy to perform, used as a screening test. This examination alone can, in the absence of factors suggestive of a post-renal or renal cause, guide the diagnosis and management.
