Severe Dehydration: Prerenal
Decreased blood flow to the kidneys due to low volume.
Sepsis: Prerenal
Hypotension from systemic infection reduces kidney perfusion.
CHF (Congestive Heart Failure): Prerenal
Reduced cardiac output leads to inadequate renal perfusion.
Benign Prostatic Hyperplasia (BPH): Postrenal
Urinary outflow obstruction causes back pressure on the kidneys
Renal Calculi (Kidney Stones): Postrenal
Blockage in the urinary tract prevents urine excretion, leading to kidney damage.
Acute Tubular Necrosis (ATN): Intrarenal
Direct injury to kidney tubules due to ischemia or toxins.
Gentamicin (Aminoglycoside antibiotic toxicity): Intrarenal
Causes nephrotoxicity, damaging renal tubules directly.
