Introduction • Definition of Acute Renal Failure (ARF): Sudden loss of kidney function • Definition of Chronic Kidney Disease (CKD): Gradual loss of kidney function over time
Pathophysiology of ARF • Pre-renal: Decreased blood flow → decreased GFR • Intrinsic: Direct damage to the kidneys • Post-renal: Obstruction of urine outflow
Pathophysiology of CKD • Progressive nephron loss • Stages of CKD (1-5) based on GFR levels
Management of CKD • Early Management: Blood pressure control, glucose control, Dietary restrictions (low protein, potassium, phosphate) • Advanced Management: Dialysis, kidney transplantation, Management of complications (anemia, bone disease)
Stages of Chronic Kidney Disease Stage Description GFR (mL/min/1.73 m²) 1 Kidney damage with normal GFR ≥ 90 2 Mild decrease in GFR 60-89 3a Mild to moderate decrease in GFR 45-59 3b Moderate to severe decrease in GFR 30-44 4 Severe decrease in GFR 15-29 5 Kidney failure < 15 or dialysis
Complications of ARF and CKD • ARF: Hyperkalemia, acidosis, uremia, fluid overload • CKD: Cardiovascular disease, anemia, bone-mineral disorder
Prognosis • ARF: Dependent on underlying cause and treatment response • CKD: Progressive; may lead to end-stage renal disease (ESRD)
Conclusion • Summary of Key Points • Importance of Early Detection and Management • Future Directions in Treatment
