The Causes of Kidney Infection and Its Treatment

Kidney infection or pyelonephritis is a serious medical condition that can cause permanent kidney organ damage. As anticipation, it is important for you to recognize things that can cause kidney infections, along with the handling.

The common cause of kidney infection is bacteria. These microorganisms can spread from infections elsewhere, such as the bladder and urethra. Kidney infection can be experienced by anyone, both children and adults.

Typical symptoms that arise due to kidney infection is the discharge of blood or pus in the urine. Other symptoms that follow can include fever, nausea, vomiting, no appetite, lower back pain, urination pain, and an unusual urine odor.

Causes of Kidney Infection



The bacteria Escherichia coli ( E. coli ) is considered as the cause of the most common kidney infection. This bacterium comes from the intestine and can come out with feces. If cleanliness is not maintained properly, bacteria can enter through the urinary opening, multiply in the urethra, and cause urinary tract infections (UTI).

If a UTI is not treated immediately, the bacteria can spread and cause bladder infections. From here, the chance for bacteria to spread to the kidneys is greater.

Apart from the lack of hygiene, several factors can also increase the risk of kidney infection:

  • Using a urine catheter in the long run
  • Having a blockage in the urinary tract, for example, due to kidney stones or prostate gland enlargement
  • Having abnormalities in the form of the urinary tract, such as urethral stricture
  • Having a weak immune system, for example, due to diabetes, HIV / AIDS, or side effects of consuming immune system-suppressing drugs
  • Suffer from nerve damage around the bladder
  • Suffer from diseases that make urination difficult (urinary retention), such as multiple sclerosis or spina bifida
  • Having an abnormality in the valve in the bladder that causes vesicoureter reflux, which is the return of urine from the bladder to the kidney
  • Undergo medical procedures, such as urinary tract surgery or cystoscopic examination

How to treat kidney infections

If the lab test shows that you have a bacterial kidney infection, the doctor will give you antibiotics, such as:

  • Levofloxacin
  • Ciprofloxain
  • Cotrimoxazole
  • Ampicillin

Antibiotics can be taken or given intravenously. Antibiotics taken must be spent in accordance with the doctor's advice, despite complaints to improve after a few days of infection.

In addition to addressing the main causes of kidney infections, doctors also need to deal with risk factors that trigger infection, so that kidney infections do not recur. If the trigger for kidney infection is a deformity of the urinary tract, enlargement of the prostate, or kidney stones, your doctor may recommend surgery to treat it.

Most of the bacteria that cause kidney infections will disappear after getting proper treatment. However, preventing infection will certainly be better. Ways that can be done are starting from cleaning intimate organs properly every urination and defecation, drinking enough water, avoiding holding back urination, and getting used to urinating after sexual intercourse.

If you often experience urinary tract infections or have other conditions that can cause kidney infections, such as enlarged prostate or kidney stones, you should consult with your doctor to find out what treatments you can take to prevent kidney infections.
