Prerenal
- Renal hypoperfusion
- GFR declines because of the decrease in filtration pressure
- If prerenal failure goes on too long, can become intrarenal failure b/c tubules are dead (tubular necrosis)
Intrarenal
- Kidneys themselves are diseased or dead
- Usually results from ischemic acute tubular necrosis related to pre renal AKI, nephrotoxic ATN, acute glomerulonephritis, vascular disease, etc.
Postrenal
- Occurs with urinary tract obstructions
that affect the kidneys bilaterally (i.e. kidney stone
- Relieve obstruction, urine flows and kidneys come back to life (leading causes: diabetes, high BP)

Symptoms usually include fever, flank pain, nausea, vomiting, burning on urination, increased frequency, and urgency.
What best describes the cause of most cases of acute glomerulonephritis?
The most common infectious cause of acute GN has historically been infection by Streptococcus species (ie, group A, beta-hemolytic). Two types have been described, involving different serotypes: Serotype 12 - Poststreptococcal nephritis due to an upper respiratory infection, occurring primarily in the winter months.
Which finding is as a manifestation of acute Poststreptococcal glomerulonephritis?
The most common presenting symptom is gross hematuria as it occurs in 30 to 50% of cases with acute PSGN; patients often describe their urine as smoky, tea-colored, cola-colored, or rusty. The hematuria can be described as postpharyngitic (hematuria seen after weeks of infection).
