Oct 7, 2024 · The glomerular filtration rate (GFR) may fall to very low levels in patients with intrinsic acute kidney injury (AKI). However, a low GFR is not necessarily associated with a parallel reduction in urine output [ 1,2 ].

INTRODUCTION AND DEFINITION. Polyuria has generally been defined as a urine output exceeding 3 L/day in adults and 2 L/m 2 in children. It must be differentiated from the more common complaints of frequency or nocturia, which may not be associated with an increase in the total urine output.

Jun 11, 2024 · Acute kidney injury (AKI), previously called acute renal failure (ARF), is a common clinical problem . The 2012 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guidelines for Acute Kidney Injury defined AKI as one or more of three criteria [ 1 ].

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.

Feb 11, 2025 · Several consensus definitions of AKI have been developed in order to provide a uniform definition of AKI. These definitions are based exclusively upon the serum creatinine and urine output and are used primarily to identify patients with …

AKI is an important contributing factor to the morbidity and mortality of critically ill neonates. The diagnostic evaluation, management, and prognosis of neonatal AKI are presented in this topic review.

Nov 7, 2023 · 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.

Oct 23, 2024 · Acute kidney injury (AKI) due to ischemic acute tubular necrosis (ATN) typically lasts 7 to 21 days , with most patients returning to or near their previous baseline level of kidney function as the necrotic tubular cells regenerate.

Nov 7, 2023 · 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.

AKI is an important contributing factor to the morbidity and mortality of critically ill neonates. The pathogenesis, etiology, presentation, and diagnosis of neonatal AKI are presented in this topic review.
