Renal System O1
Anuria/Oliguria Case Closing- Ratliff- 2/1/2013
| Question | Answer |
|---|---|
| 2 most common causes of chronic kidney disease that predispose to development of acute kidney injury in setting of other exposures | Diabetes and hypertension |
| "I am not making much urine" goes under which section of a note | Chief complaint |
| By which mechanism does an ACE inhibitor increase risk of AKI | It blocks the conversion of Angiotensin I to Angiotensin II which inhibits vasoconstriction of the efferent arteriole which is needed to maintain GFR in decreased blood pressure or volume |
| Effect of NSAID on Renal Blood flow | Vasoconstricts afferent arteriole |
| Effect of ANP on Renal Blood flow | Vasodilates afferent arteriole |
| Effect of Prostaglandin on Renal Blood flow | Vasodilates afferent arteriole and vasoconstricts efferent arteriole |
| Effect of Angiotensin II on Renal Blood flow | Vasoconstricts efferent arteriole |
| Effect of Norepinephrine on Renal Blood flow | Vasoconstricts efferent arteriole |
| Effect of ACE inhibitor on Renal Blood flow | Vasodilates efferent arteriole |
| Rash in a kidney patient can be indicative of | Glomerulonephritis or autoimmune (lupis) |
| Frothy urine is indicative of | Proteinuria |
| Tea colored urine is indicative of | Hematuria or rhabdomylosis |
| Tachycardia, hypotension, reduced skin turgor with tenting and syncope are all findings supporting | Volume depletion |
| Definitive way of diagnosing post-renal causes | Ultrasound |
| Increased Lactic acid levels are due to | Ischemia/hypoperfusion |
| Lack of blood and protein in the urine points to | Pre-renal causes |
| In pre-renal disease, a decreased flow leads to increased reabsorption of | BUN |
| A BUN:CR for pre-renal etiologies | >20 |
| Decreased pressure and flow lead to activation of | RAAS |
| Urine sodium levels for pre-renal etiologies | <20 |
| Explain why urine sodium levels are low in pre-renal disease | In cases of depleted volume, Kidneys will activate RAAS and maximally reabsorb sodium and therefor increasing water retention. This will happen as long as TUBULES ARE INTACT |
| RBCs or RBC casts are indicative of | Intrinsic glomerular disease |
| "Muddy brown" granular casts are indicative of | Intrinsic Tubular disease |
| WBCs and WBC casts with a negative urine culture are indicative of | Intrinsic Interstitial disease |
| High BUN:CR and Low Na+ points to | Pre-renal disease |
| Low BUN:CR and high Na+ points to | Intrinsic renal disease |
| High BUN:Cr and high Na+ points to | Post-renal disease |
| Pre-renal etiology is due to | True volume depletion or medications affecting renal blood flow |
| Plan for patient with pre-renal causes | IV fluid hydration and holding potential offending medications |
| Anuria | Absence of urine formation (<100 ml/day) |
| Oliguria | Scanty urine production (<400-500 ml/day) |
| Normal urine production | >500 ml/day |
| Nephrotoxic | Toxic to renal cells |
| Nephritic | Relating to or suffering from nephritis |
| Nephritis | Inflammation of the kidneys (RBC in urine) |
| Nephrotic | Relating to, caused by, or similar to nephrosis |
| Nephrosis | Damage to renal tubular epithelium/glomerular basement membrane (protein in urine) |
| General cause of prerenal disease | Less fluid is delivered to the kidneys for filtration |
| General cause of intrinsic renal disease | The kidneys are unable to produce urine to due intrinsic disease |
| General cause of Postrenal disease | The kidneys are obstructed and urine cannot be excreted |
| Nephritic urine sediment suggests | Glomerulonephritis |
| Sterile pyuria suggests | Interstitial nephritis |
| Proteinunuria suggests | Intrinsic/Glomerular process |
