What does it mean that the kidney is suppurated and bacteria may enter the blood? Can it be treated? Tell me in detail

When bacteria multiply in the kidney, pus produced by bacteria will be released. Because all organs are connected to blood vessels, bacteria in the kidney may leave the kidney with the blood.

Blood is rich in nutrients, because it needs to be supplied to the whole body organs, bacteria like these nutrients very much, and will use these nutrients for reproduction, and with the whole body movement of blood, it may cause pathological changes in other organs.

That's what it means.

Of course, treatment can be treated, which is nothing more than hanging salt water and antibiotics into blood vessels to kill these bacteria. It may be necessary to do pus discharge and other treatments to drain the pus out, which will be better and faster.
