Article Synopsis
- Oliguria, a condition characterized by decreased urine output, may be misinterpreted as acute kidney injury (AKI) in patients post-surgery, despite being a potential adaptive response during surgery.
- A study analyzing 1,476 patients revealed that 34.4% exhibited oliguria within the first 24 hours after surgery, with certain factors like vasopressor use and non-elective procedures linked to increased risk.
- Although oliguria was associated with a higher rate of AKI development compared to non-oliguric patients, 87.6% of oliguric patients did not show kidney dysfunction based on serum creatinine levels, questioning the accuracy of oliguria as an indicator for AKI.

Intravenous volume loading is a common treatment when hypovolemia is a potential cause of oliguria. We studied whether the effectiveness of Ringer's solution and 20% albumin in inducing diuresis differs depending on the mean arterial pressure (MAP). For this purpose, volume kinetic analysis was performed based on urine output and hemoglobin-derived plasma dilution obtained during and after 136 infusions of Ringer and 85 infusions of 20% albumin.

Objective(s): Acute kidney injury (AKI) is defined and staged by reduced urine output (UO) and increased serum creatinine (SCr). UO is typically measured manually and documented in the electronic health record, making early and reliable detection of oliguria-based AKI and electronic data extraction challenging. The authors investigated the diagnostic performance of continuous UO, enabled by active drain line clearance-based alerts (Accuryn AKI Alert), compared with AKI stage 2 SCr criteria and their associations with length of stay, need for continuous renal replacement therapy, and 30-day mortality.
