Renal abscesses are caused by urinary tract infection that begins in the bladder and spreads to and around the kidneys. Read more about this topic!
Renal abscess: symptoms, risk factors and treatment

Renal abscesses are abscesses in one or both kidneys. Unfortunately, kidney abscesses are associated with a high mortality rate because they are difficult to diagnose. They occur at an average age of 46 years, and in 80% of cases in women. They are rare in children. Their consequences can be serious; these can include sepsis, severe kidney damage, or even kidney loss.

Renal abscesses: risk factors

Renal abscesses are abscesses of one or both kidneys

Experts have identified some predisposing factors for kidney abscesses, the most important of which are:

  • Diabetes.
  • Kidney stones.
  • Urinary tract infection.
  • Hydroureteral reflux (urine reflux).
  • Injuries in the area.
  • Malignant neoplasms.
  • Liver disease.

40% of patients have numerous risk factors. Patients diagnosed with diabetes more than 10 years ago need more intensive treatment and kidney surgery.

Symptoms usually last an average of 11 days before being diagnosed. But only 35% of patients get the correct diagnosis when they get to the hospital. This is due to the lack of specific clinical data.

Causes of kidney abscesses

Renal abscesses are caused by urinary tract infections that spread from the bladder to the kidneys and around the kidneys. Surgery of the urinary tract or reproductive organs or infection of the bloodstream can also lead to kidney abscesses.

The biggest risk factor is kidney stones, which block the flow of urine and can cause inflammation. Bacteria tend to stick to kidney stones, and antibiotics are unable to kill them there.

Renal abscesses: symptoms and diagnosis

Kidney abscesses can cause back pain

Some of the symptoms of kidney abscesses include chills, fever, sweating, and pain in the side or abdomen. Pain can also radiate to the groin or legs. The back can also feel tender.

Diagnostic tests include:

  • Blood tests and blood culture.
  • Cat scan.
  • Urine analysis through urine culture.

Treatment of renal abscesses

The most commonly accepted treatment is to clear wet abscesses, either through the skin with a catheter or by open surgery.

Antibiotics should also be prescribed, initially intravenously. Later, the patient may switch to oral medication once the infection has resolved. Emptying through open surgery is the option that is most likely to help with kidney abscesses.

Treatment of renal abscesses with antibiotics

Antibiotics are the primary treatment for kidney abscesses. Medications and duration of treatment depend on the state of health. The doctor must also take into account the bacteria found in the urine test.

Usually, the symptoms of nephritis begin to disappear within a few days of starting treatment, but the patient may need to eat antibiotics for a week or longer.

It is generally recommended that a new urine culture be used after treatment to ensure that the infection is gone. If the infection persists, the patient will need new antibiotic treatment.

If the infection is severe, the patient may need to be hospitalized. Hospitalization may include intravenous antibiotics and hydration.

To improve the condition during treatment, the patient can take the following measures:

  • Use of a thermal bath. Place a heat bath over your abdomen, back or side to relieve pain.
  • Take painkillers. Fever can be reduced and relief is felt by taking painkillers such as acetaminophen or ibuprofen.
  • Drink fluids. Adequate hydration can help remove bacteria through the urinary tract. Avoid alcohol and coffee until the infection is gone.

Kidney abscesses are a serious problem that requires medical attention. If you notice any possible symptoms, it is best to see a doctor so that the problem does not lead to fatal consequences.
