Abstract:
Acute kidney injury (AKI) is associated with a significant burden of mortality worldwide. Each episode of AKI increases the long-term risk of death, especially if there is no recovery or insufficient renal recovery (i.e. restoration of kidney function). This narrative review summarizes relevant studies on the definition and prediction of renal recovery. The following databases were searched for references: PubMed, Web of Science, Cochrane Library, Scopus. The period lasted from 1990 until 2024. The currently available criteria for renal recovery have been identified and discussed. Regarding restoration of kidney function prediction, seven studies on alternative or novel biomarkers have been reviewed. In the context of kidney replacement therapy and renal recovery, findings from four large, prospective randomized studies have been summarized. A standardized definition of renal recovery is presently not available. Specific biomarkers allow for an estimation of the likelihood of renal recovery under certain conditions. According to current knowledge, no dialysis method has been definitively shown to be advantageous for the recovery process.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
