WebMay 12, 2024 · Acute kidney injury (AKI) is an abrupt and usually reversible decline in the glomerular filtration rate (GFR). This results in an elevation of serum blood urea nitrogen (BUN), creatinine, and other metabolic waste products that are normally excreted by the kidney. In addition, if urine output is also diminished, fluid retention and volume ... WebIn the early course of a postrenal AKI, the BUN:Creatinine ratio is typically greater than 15:1. With gradual tubular cell damage, the BUN : Creatinine ratio falls below 15:1. Sodium levels in the urine are initially low, but begin to rise with the increased tubular damage.
