Clinical Overview: Renal Failure (Kidney Failure) Renal failure occurs when the kidneys lose the ability to sufficiently filter waste products from the blood to sustain life. This condition can manifest as either , characterized by a sudden and often reversible decline in function, or Chronic Kidney Disease (CKD) , a progressive condition that may eventually lead to End-Stage Renal Disease (ESRD) . 1. Classification and Epidemiology
Chronic Kidney Disease Diagnosis and Management: A Review - PMC renal failure
Defined by rapid changes in serum creatinine levels or urine output. It is often caused by sudden trauma, severe infection, or drug toxicity. A normal eGFR is above 60; levels below
Classified into five stages based on the Estimated Glomerular Filtration Rate (eGFR) . A normal eGFR is above 60; levels below this for extended periods indicate progressive damage. A normal eGFR is above 60
The leading causes of renal failure globally are and diabetes , which together account for approximately two-thirds of all cases.
Approximately 850 million people worldwide (over 10% of the population) are affected by kidney disease. It is projected to become the fifth leading cause of death globally by 2050. 2. Pathophysiology and Causes
