For each classification of azotemia, there are unique etiologies. Prerenal azotemia manifests from some insult/injury source before the kidney.
[1] Intrinsic azotemia results from damage to the structure of the kidney; the structures affected include glomeruli, renal tubules and interstitium, and renal vasculature. This can result from inflammatory conditions, such as vasculitis, toxins, drugs, infections, and damage from hypoperfusion.
A disorder characterized by the acute loss of renal function and is traditionally classified as pre-renal (low blood flow into kidney), renal (kidney damage) and post-renal causes (ureteral or bladder outflow obstruction).
Laboratory evaluation for azotemia includes a basic metabolic panel (BMP), BUN/Cr, urinary sodium (Na), protein, Cr, urea, urine osmolality (Ur Osmo), urinalysis (UA). Radiographic evaluation can be with a renal US (ultrasound), CT of the abdomen and pelvis with or without contrast, or renal Doppler examination.
Prerenal azotemia is assigned to code 788.9, Other symptoms involving urinary system.

Clinical syndrome characterized by a sudden decrease in glomerular filtration rate, usually associated with oliguria and always associated with biochemical consequences of the reduction in glomerular filtration rate such as a rise in blood urea nitrogen (bun) and serum creatinine concentrations.
A disorder characterized by the acute loss of renal function and is traditionally classified as pre-renal (low blood flow into kidney), renal (kidney damage) and post-renal causes (ureteral or bladder outflow obstruction).
Prerenal azotemia manifests from some insult/injury source before the kidney. Most commonly, we see this in the form of hypoperfusion, or decreased blood flow, to the kidneys from various etiologies of volume depletion, such as the physiologic state shock, dehydration, hemorrhage, over-diuresis, burns, and even intravascular depletion from low-oncotic pressure states, such as congestive heart failure and liver failure.

Azotemia is a biochemical abnormality, defined as elevation, or buildup of, nitrogenous products (BUN-usually ranging 7 to 21 mg/dL), creatinine in the blood, and other secondary waste products within the body.
With that said, azotemia is quite common, responsible for 8% to 16% of hospital admissions and more so associated with a significantly higher risk of mortality.[3] . There is a need for studies to help understand new knowledge about the incidence of AKI and its epidemiology.
Some of the most common findings in AKI include ischemia, apoptosis, tubular necrosis, the detachment of renal epithelial cells from the basement membranes, effacement of the brush border in proximal tubules, tubular casts from sloughing of cells, interstitial edema, and even peritubular capillary congestion. [5]
Along with that line, blood pressure goals are just important as well, not only in keeping the BP range less than 140/90 mmHg but also in ensuring the appropriate choice of medications to reduce nephrotoxic side effects of the drugs.
If an azotaemic animal has a urine SG less than these values then the patient must have impaired urine concentrating ability, because if the azotaemia was due to pre-renal factors only and the patient had normal renal concentrating ability, the urine SG would be >1.030 (dogs) or 1.035 (cats). Note that most dehydrated cats with normally functioning kidneys will have a urine SG > 1.045.
If a patient has been confirmed as being polyuric and polydipsic and/or azotaemia has been identified, the initial and most important diagnostic step is to determine the urine specific gravity (SG) --without this information, appropriate interpretation of other pathology results can be difficult.
Prerenal processes include hypovolaemia and severe dehydration. Mild azotaemia may also occur after a large meat meal and when there is GI bleeding.
However, if an animal with a polyuric disorder such as pyometra, hyperadrenocorticism or liver disease becomes dehydrated it may become azotaemic entirely due to the prerenal factor of dehydration but it may still have inappropriately dilute urine (because of the factors that interfere with urine concentration).
Hypercalcaemia-- calcium causes constriction of the afferent arteriole in the glomerulus thus decreasing GFR and hence causing azotaemia.
Too often a patient with low urine SG and azotaemia is diagnosed as having renal failure--this is of course a very possible diagnosis especially in cats, but there are other disorders that impair both urine concentration and cause azotaemia that the practitioner must always consider.
Hyponatraemia-- due to hypovolaemia--sodium is the osmotic backbone of the plasma, thus loss of sodium reduces total body water and blood volume which in turn reduces GFR and therefore results in azotaemia. Low sodium also impairs the natural osmotic stimuli for ADH secretion (low serum osmolality) and so promotes dilute urine despite the dehydration which exacerbates fluid loss and therefore pre-renal azotaemia.
Symptoms of AKI. Signs and symptoms of acute kidney failure may include decreased urine output (although occasionally urine output remains normal), fluid retention, swelling in your legs or feet, shortness of breath, fatigue, confusion, nausea, weakness, irregular heartbeat, chest pain, pressure, seizures, or a coma in severe cases.
If you were healthy before your kidneys suddenly failed and you were treated for AKI right away, your kidneys may work normally or almost normally after your AKI is treated. Some people have lasting kidney damage after AKI. This is called chronic kidney disease, and it could lead to kidney failure if steps are not taken to prevent the kidney damage from getting worse.
