The Kidney Bladder Infection Connection

Your kidneys and bladder are both important parts of your urinary system. The kidneys and bladder are connected through two slender tubes known as ureters (see the picture below). One comes out of each kidney and connects to the bladder. This connection of kidney, bladder and ureters makes up part of what is known as your urinary tract.

Those who search for the keywords "kidney bladder" on the Internet usually do so because they have symptoms of a kidney problem or bladder disorder, but may not be sure if the kidney or the bladder are the cause.

The most common disorder in the urinary tract is a urinary tract infection, also known as a UTI.

A bladder infection is generally annoying because it causes stinging or burning pain, especially during urination. But it usually goes away on its own in a few days, or when treated with antibiotics.

But sometimes the germs can migrate up through the ureters and invade the kidneys. This can result in a kidney infection, which is a much more serious situation. If a kidney infection becomes chronic, it can eventually lead to kidney failure, which can be fatal. When your kidneys fail, you must depend on kidney dialysis or a kidney transplant to survive.

Kidney infections

Pyelonephritis happens when the kidneys become irritated due to a bacterial infection. Pyelonephritis is the type of infection that starts in the bladder and travels upward.

Glomerulonephritis involves an inflammation of the renal glomeruli of the kidneys. Glomeruli are blood vessels in the nephron, the part of the kidney where blood is filtered. Glomerulonephritis can be acute or it can be chronic. Acute glomerulonephritis typically starts as a result of a strep infection elsewhere in the body, especially the respiratory tract. Sometimes it may be preceded by a skin infection such as impetigo.

Kidney infection symptoms include back pain, fever or chills, nausea, cloudy, foul smelling urine, and unexplained weakness or fatigue.

Bladder infections

Approximately four out of five bladder infections are caused by Escherichia coli, or E. coli bacteria. These are generally found in stool and sometimes remain on the skin in the rectal area after a bowel movement. From there, they can be transferred to the genital area, where they enter the urinary tract and eventually get into the bladder, causing an infection.

Due to differences in anatomy, women are more likely to get a bladder infection than men. Research indicates about half of all women will have at least one bladder infection in their lifetime.

Bladder infection symptoms are generally easy to identify because they happen fast and cause a burning sensation during urination, an urge to urinate often even though not much urine passes, and a mild fever. Urine may also look darker than usual.


Bladder problems often clear up quickly when treated with antibiotics. Symptoms may begin to fade within hours, although some mild discomfort may persist for a few days.

The best treatment for a kidney infection depends on the type of infection you have. Glomerulonephritis requires rest and antibiotics. Treatment usually takes up to two weeks.

In the case of pyelonephritis, the most important steps involve killing the bacteria at the root of the infection.
