A kidney infection needs to be treated urgently with antibiotics. If its not treated quickly, the infection can get worse and cause . This can cause permanent damage to your kidneys and can even lead to death.

What If I Don’t Go To The Doctor

What happens when UTIs are left untreated? Contrary to popular belief, your immune system is often able to clear a UTI on its own. Studies have found that 25-42% of women are able to recover from an uncomplicated UTI without antibiotics.

But that means a majority of UTIs do not go away on their own. If left untreated, they can lead to continued discomfort and other more serious health issues, such as kidney damage or a severe infection. Therefore, treatment is recommended.

“Physicians tailor care plans to each patient, and there is no sole treatment for everyone,” says Stanford physician Kim Chiang, MD. During your visit, feel free to ask in-depth questions, particularly if a non-recommended antibiotic is prescribed.

This is the fifth post in the series Understanding UTIs. The goal of this seven-part series is to provide easy-to-understand, scientifically grounded information about UTIs. Patients referenced are composites, compiled from actual patient experiences.Data on medications used for UTIs were extracted from the National Disease and Therapeutic Index, a nationally representative physician survey produced by IQVIA.

Which Antibiotics Are Used For The Treatment Of Complicated Acute Pyelonephritis

With complicated acute pyelonephritis, treat patients parenterally until defervescence and improvement in the clinical condition warrants changing to oral antibiotics. Complete the course of therapy with an oral agent selected on the basis of culture results. Acceptable regimens include the following:

  • Ampicillin and an aminoglycoside
  • Ceftazidime-avibactam
  • Meropenem-vaborbactam

If the patient is allergic to penicillin, vancomycin should be substituted. Vancomycin or linezolid are options if enterococci are a consideration.

Meropenem-vaborbactam is a combination of the carbapenem antibiotic meropenem with the beta-lactamase inhibitor vaborbactam. Specifically, vaborbactam inhibits bacterial production of the Klebsiella pneumoniae carbapenemase enzyme, which confers resistance to carbapenems. The US Food and Drug Administration has approved meropenem-vaborbactam for adults aged 18 years and older with pyelonephritis and other complicated urinary tract infections caused by designated susceptible Enterobacteriaceae: Escherichia coli, K pneumoniae, and Enterobacter cloacae species complex.

Antibiotics And Kidney Damage

Certain medications are known for their potential to cause kidney damage, leading to acute kidney injury or even CKD. Acute kidney injury is the deterioration of renal function over hours or days and involves both structural damage and loss of function. Medications are one of the most common causes of AKI.

Antibiotics are the most common drugs implicated in reports of drug-induced nephrotoxicity. Certain classes of antibiotics are better known for their nephrotoxic potential, and they include:

  • Aminoglycosides eg. Gentamicin, Tobramycin, Streptomycin and Neomycin
  • Beta-Lactams- this group includes penicillins, cephalosporins and carbapenems.
  • Vancomycin
  • Amphotericin B- is actually an anti-fungal not an antibiotic

The way that antibiotics cause kidney injury varies depending on the antibiotic involved and the consequences vary from mild forms of tubular injury to significant deterioration of kidney function requiring acute renal replacement therapy .

Here are some of the consequences of nephrotoxic antibiotics:

  • Acute interstitial nephritis- inflammation and swelling in the kidney.
  • Acute tubular necrosis- damage to the kidney tubules largely due to high levels of oxidative stress.
  • Intratubular crystal deposition- some medications are insoluble in urine and form crystal deposits in the tubules causing acute or chronic kidney injury.
  • Tubular cell toxicity- direct toxic effect of drugs on kidney tubular cells.

How Do Doctors Treat A Kidney Infection

Doctors will often first prescribe an antibiotic that fights the most common types of kidney infection because it is very important to treat a kidney infection right away.

  • What type of bacteria is causing the infection
  • How severe the infection is
  • If you are you are pregnant
  • If you are older than 65
  • If you had problems from certain antibiotics in the past, such as allergic reactions

If you have a very serious infection, you may need to stay in the hospital to get antibiotics through an IV . You may also get medicine for pain.

If your kidney infection was caused by a problem with the shape of your urinary tract, you may need to have surgery to correct the problem and prevent future kidney infections.

Once the actual bacteria are recovered and their sensitivity is determined, then a different antibiotic may be selected if the bacteria show resistance to the antibiotic that was originally started.

Several types of antibiotics are available and used to treat kidney infection. The choice depends on specific situations, clinical setting, tolerance, allergies, and ability to take oral medications.

  • The infection can sometimes cause some permanent damage to kidney tissues.

These complications are uncommon but may be more likely if:

Emphysematous pyelonephritis is also a rare complication.
