Oct 7, 2024 · This topic addresses urine output in AKI and associations between lower urine volume, AKI severity, and increased mortality. The evaluation and management of AKI, as well as kidney and patient outcomes after AKI, are discussed separately:

Mar 16, 2023 · Oliguria is a subset of acute kidney injury defined by low urine output (<0.3-0.5 ml/kg/hr for several hours, or roughly <500 ml/day). (29156029) Although oliguria has traditionally often been interpreted as a surrogate for hypovolemia, this is not accurate.

Dec 13, 2023 · The difference in urine output between oliguric and nonoliguric acute kidney injury (AKI) may be due to one of two factors: Nonoliguric patients may have a higher glomerular filtration rate (GFR) than those with oliguria, and/or they may reabsorb less in the tubules.

These findings suggest that oliguria, as defined by the KDIGO criteria, is associated with mortality in AKI and should be accounted for by clinicians at the bedside and clinical researchers while designing trials.

During critical illness, oliguria is often used as a biomarker of acute kidney injury (AKI). However, its relationship with the subsequent development of AKI has not been prospectively evaluated. We documented urine output and daily serum creatinine ...

Back pain. Decreased urine output (oliguria). zure or coma in severe cases. hatemia, uremia, and azotemia. Although the severity of symptoms and the complexity of renal dysfunc-tion vary, the clinical course and manifestations of AKI gen-erally progress over the following four phases (Dirkes, 2015; Lewis, Dirksen, Heike output less than 0.5 mL ...

Low urine output, also called oliguria, can happen for many reasons, including acute kidney injury or ordinary dehydration during an illness. Treatment depends on the cause of reduced urine production.

Nov 1, 2021 · The findings of this cohort study suggest that oliguria lasting more than 12 hours (KDIGO stage 2 or 3) has major AKI diagnostic implications and is associated with outcomes irrespective of sCr elevations.

Acute Kidney Injury (AKI) is defined using widely accepted international criteria that are based on changes in serum creatinine concentration and degree of oliguria.

It is characterized by a sudden decline in renal excretory function over hours or days that can result in failure to maintain fluid, electrolyte, and acid-base balance. The diagnosis of AKI and its staging is based on acute changes in serum creatinine and/or a …
