Study Notes
Acute Kidney Injury: Clinical Presentation
- The most common symptoms stem from the accumulation of toxic metabolites.
- Other symptoms include Oliguria of less than 400 ml/day and Anuria of less than 100ml/day
- Additional symptoms include fatigue, malaise, anorexia, nausea, vomiting, pruritus (itching), and mental status changes such as listlessness and confusion.
Acute Kidney Injury: Clinical Presentation (cont'd)
- Initiating stage: kidney is injured, decreased urine volume; anorexia, lethargy, nausea, headache, muscle cramps, and fatigue may be present.
- Oliguric stage: lasts 5-15 days; renal repair begins as tubular cells regenerate; nephrons become obstructed with inflammatory products; decrease in glomerular filtration, tubular transport of substances, urine formation, and renal clearance occur; the longer this stage persists, the poorer the prognosis.
- Diuretic stage: characterized by urine output that is greater than 400mL/day and BUN begins to fall.
- Recovery stage: extends from the time BUN is stable and urine output is normal to the day the patient returns to normal activity; the entire process can take up to 10 months.
- Some patients never recover and instead progress to chronic renal failure.
Acute Kidney Injury: Clinical Presentation (cont'd) Objective data
- Objective data to note included orthostatic vital signs, skin turgor, and distention of jugular veins to assess fluid balance.
- Key things to assess in diabetic patients are AV nicking, diabetic retinopathy, and papilledema.
- Fluid depletion may indicate prerenal etiology while fluid overload suggests a greater degree of renal impairment.
- JVD, adventitious lung sounds, a third heart sound, and edema indicate volume overload.
- Severe proteinuria may lead to generalized edema.
- Abdominal renal artery bruits can suggest renovascular disease.
Acute Kidney Injury: Diagnostic Testing
- Hallmark diagnostic signs: decreased GFR, increased serum creatinine and albumin in urine. These indicators can establish the diganosis of ARF
- Elevated BUN and serum creatinine levels assist in establishing the diagnosis of ARF.
- Monitor serum electrolyte levels because potentially life-threatening abnormalities develop secondary to renal disease.
- Presence of RBCs suggests a vascular or glomerular lesion.
- WBCs with associated infection
- Eosinophiluria is indicative of allergic interstitial nephritis (AIN) due to renal toxic drugs.
- Urinary sodium tends to be less than 20 mEq/L in prerenal disease, and Urinary sodium values typically greater than 40 mEq/L indicate ATN.
- In diabetic or hypertensive patients, regular urinalysis should have the calculation of the urinary albumin to creatinine ratio (ACR) to allow for early detection of kidney damage (can lead to CKD).
Acute Kidney Injury: Diagnostic Testing (cont'd)
- Diagnostic tools involve renal ultrasound, CT scan, retrograde pyelogram, and cystoscopy.
- A renal biopsy is performed to confirm diagnosis of acute nephritic syndrome, to better characterize nephritic syndrome or suspected vasculitis, and to aid in the diagnosis of acute or subacute renal failure of unknown etiology.
Acute Kidney Injury: Follow-up and Referral
- Following hospitalization, schedule follow-up appointments about one week, one month, three months, and six months after, and annually thereafter.
- At each follow-up visit, check a basic metabolic profile and CBC.
- Regularly assess for signs and symptoms of fluid overload during follow ups.
