Flashcards
Pre-renal AKI Causes
Pre-renal AKI Causes
Disruptions in renal perfusion and blood flow leading to AKI. Examples include shock, dysrhythmias, heart failure, hypovolemia, GI losses/bleeding, and ruptured aortic aneurysm.
Intra-renal AKI Causes
Intra-renal AKI Causes
Direct damage to the kidney tissue itself leading to AKI. The #1 cause in-hospital is acute tubular necrosis (ATN) from ischemia, nephrotoxins (like vancomycin, NSAIDs), and sepsis; also prolonged pre-renal causes.
Post-renal AKI Causes
Post-renal AKI Causes
Obstruction of urine outflow, causing AKI. Examples include BPH, bladder cancer, kidney stones, prostate cancer, or trauma.

Study Notes
- AKI can stem from issues affecting kidney perfusion, direct kidney damage, or urinary outflow obstruction.
Pre-Renal Causes of AKI
- Disrupted renal perfusion and blood flow are the primary issues.
- Common causes include shock, dysrhythmias, heart failure (HF), hypovolemia, GI losses/bleeding, and ruptured aortic aneurysms.
Intra-Renal Causes of AKI
- Direct damage to kidney tissue is the main factor.
- Acute tubular necrosis (ATN), often due to ischemia, nephrotoxins, and sepsis, is a leading cause in hospital settings.
- Strong antibiotics like vancomycin, NSAIDs, and prolonged pre-renal issues can lead to this.
Post-Renal Causes of AKI
- Obstruction of urine outflow is the main problem.
- Benign prostatic hyperplasia (BPH), bladder cancer, kidney stones, prostate cancer, or trauma can cause obstructions.
Oliguric Phase of AKI
- This initial phase occurs 1-7 days after the injury.
