According to the KDIGO staging, AKI Stage 1 involves at least one of:

- Creatinine rise of 1.5x compared to baseline
- Urine output <0.5 ml/kg/hour for 6-12 hours.

There should be no features of stage 2 or 3 AKI. In this case, there is no access to blood tests to determine the creatinine but the urine output has been 0 for the past 16 hours, which meets the criteria for a stage 3 AKI.

A 45-year-old man has just finished running a marathon. He is now feeling unwell, and his friends are concerned because he looks pale and sweaty. A paramedic on the scene examines him and determines that he is tachycardic with a low blood pressure of 100/65.

The marathon runner admits to not keeping himself hydrated throughout the day as well as for a few days prior to the marathon. He has not passed any urine over the past 16 hours.
