Acute kidney damage: the cause of the damage

2021-05-06 02:13 PM

The causes of acute kidney damage (AKI) can be divided into three main causes: acute pre-kidney damage, acute renal damage, and acute post-renal damage.

 

The causes of acute kidney damage (AKI) can be divided into three main causes:

1. Acute pre-kidney damage to the kidneys: Due to decreased blood flow to the kidneys. This condition is often referred to as acute pre-kidney damage to reflect the cause of the external organs of the kidney. For example, acute pre-kidney damage may result from heart failure with decreased cardiac output and hypotension or conditions associated with decreased blood volume and hypotension, such as blood loss. level.

2. Acute kidney damage to the kidney: is the result of abnormalities in the kidney, including the kidney blood vessels, glomeruli or tubules.

3. Acute post-renal damage to the kidneys: is the result of obstruction of the urine-collecting system anywhere from the kidney stations to the bladder. The most common causes of extra-renal urinary obstruction are kidney stones, a result of deposition of calcium, urate, or cystine.
