A kidney infection is one of several types of infections that can affect the urinary system. These types of
infections are often called UTIs or urinary tract infections.
Generally, there are two types of kidney infections: pyelonephritis and glomerulonephritis.
The animated video below gives you a brief but concise explanation of what a urinary tract
infection is, how it occurs and how the kidneys may be involved.
Kidney infections may also be acute or chronic. Both types can be dangerous because they may
eventually cause kidney damage that is so serious that kidney function can be damaged. Kidney failure is even
possible.
