N28: Other disorders of kidney and ureter, not elsewhere classified

N28.0: Ischaemia and infarction of kidney

There are normally 2 kidneys in the body. They filter blood and create urine. They thus help to detoxify the body. Furthermore, the kidneys regulate the blood pressure and salt content in the blood, among other things.

Blood vessels supply the kidneys with oxygen-rich blood. If a blood vessel is partially or completely sealed, for example, not enough oxygen-rich blood may get to the kidney tissue. When supply of oxygen-rich blood to the kidney tissue is inadequate, part or all of the kidney tissue can die off. This can cause severe pain. You may also have blood in your urine.
