Excerpt

We read with interest the article by Aniort et al. [1] and would like to make some comments about their findings. Despite the limitations of the study, their data were able to highlight that urine assessment in critically ill patients must not be restricted merely to volume or flow. Recent studies have demonstrated the relevance of assessing both urinary electrolytes [2] as well as the amount of creatinine excreted [3] in order to best monitor acute kidney injury (AKI) development and recovery. There are relevant increments in the information retrieved from urine when its composition is taken into account [4, 5]. …
