Acute Kidney Failure (AKF): Definition & Clinical Context
Acute Kidney Failure (AKF) – now termed Acute Kidney Injury (AKI) – is a sudden (<48h) decline in renal filtration function, leading to azotemia (↑BUN/Cr), electrolyte imbalance, volume overload, and potentially uremia.
KDIGO stages by creatinine rise / urine output. Requires prompt cause identification (pre-renal, intrinsic, post-renal) and supportive management.
