| '''Azotemia''' is a medical condition characterized by abnormal levels of [[nitrogen]]-containing compounds, such as [[urea]], [[creatinine]], various body waste compounds, and other [[nitrogen]]-rich compounds in the [[blood]]. The cause is usually insufficient filtering of the blood by the [[kidney]]s.
| |
|
| |
|
| Azotemia can be classified according to its cause. In '''prerenal azotemia''' the blood supply to the [[kidney]]s is inadequate. In '''postrenal azotemia''' the urinary outflow tract is obstructed. Other forms of azotemia are caused by diseases of the [[kidney]]s themselves.
| |
|
| |
|
| Other causes of azotemia include [[congestive heart failure]], [[shock]], severe [[burn]]s, prolonged [[vomiting]] or [[diarrhea]], some antiviral medications, [[liver]] [[failure]], or [[trauma]] to the [[kidney]]s.

| [[Uremia]] is a broader term referring to the pathological manifestations of severe azotemia. Azotemia is one of many clinical characteristics of uremia, which is a syndome characteristic of [[renal disease]]. [[Uremia]] includes azotemia, as well as [[acidosis]], [[hyperkalemia]], [[hypertension]], [[anemia]] and [[hypocalcemia]] along with other findings.

| A [[urinalysis]] will typically show a decreased urine sodium level, a high urine creatinine-to- serum creatinine ratio, a high urine urea-to-serum urea ratio, and concentrated urine (determined by osmolality and specific gravity). None of these is particularly useful in diagnosis.
| |
|
| |
| Prompt treatment of some causes of azotemia can result in restoration of kidney function; delayed treatment may result in permanent loss of renal function. Treatment may include [[hemodialysis]] or peritoneal [[dialysis]], medications to increase cardiac output and increase blood pressure, and the treatment of the condition that caused the azotemia to begin with.
