Kidney infection or pyelonephritis is of bacterial originand may affect either one or both kidneys. In 90% of all kidney infections thecause is bacteria known as Escherichia coli. The infection usually starts inthe bladder, moves up and affects the kidneys.
Some conditions are known to decrease defense mechanisms ofthe body and thus are associated with kidney infections. Abnormalities of theurinary tract, pregnancy and diabetes may make people more prone to theseinfections. People suffering from kidney stones or cancer may also experiencekidney infection due to the weakened immune system. Women may get infectedafter the entrance of bacteria to their urinary tract after sexual intercourse.Extended use of Foley catheters is also connected to increased risk of kidneyinfections.
There is a difference between the acute and chronic kidneyinfection. Acute kidney infection starts all of a sudden, the symptoms areusually very severe but it also ends up rapidly. In the case when someonesuffers from chronic kidney infection, the condition is known to progressslowly and become worse over a certain period of time.
