Urinary tract infections (UTIs) are very common, particularly in women. Approximately half of all people will have at least one UTI in their lifetime, and almost all will recover fully from a UTI if they receive treatment soon after experiencing symptoms. For this reason, UTIs are sometimes regarded as minor or routine infections. But when UTIs happen repeatedly or are not treated effectively, they can also quietly harm the kidneys and — in a few cases — cause them permanent damage.
For the sake of long-term kidney health, it’s crucial to know when UTIs become dangerous as well as how they progress.
How UTIs Can Lead to Kidney Infections
The majority of UTIs start in the lower urinary tract. Treated early, the infection universally clears without any complications. The trouble comes when bacteria move up from your bladder to your kidneys. This is called kidney infection or pyelonephritis, and it’s much more serious than a plain old UTI.
One consequence of recurrent kidney infections is that they can inflame kidney tissue multiple times. Repeated inflammation can eventually cause scarring. Unlike most organs in the body, the kidneys cannot grow back damaged tissue, which is why repeated infections are a long-term risk.
Can Frequent UTIs Actually Do Permanent Harm?
Yes, repeated UTIs can result in permanent damage to the kidneys, but not for everyone. The more frequent, serious, untreated or ignored infections the greater is the risk. There is a 1% risk of the kidneys being affected for each untreated or half-treated infection.
When the kidneys are scarred, damage is usually permanent. This can cause a slow loss of kidney function, and occasionally may even develop into chronic kidney disease (CKD). Early identification and treatment is essential to avoid this.
How More Likely Are Women to Suffer Kidney Injury From UTIs?
Some people are more susceptible to complications from repeat UTI. People with diabetes are particularly susceptible, as high blood sugar can weaken the immune system and allow bacteria to grow. Individuals with kidney stones, benign prostatic hypertrophy or structural urinary abnormalities may have inefficient urine flow, permitting bacteria to increase in numbers.
Children that have recurrent UTIs represent another high risk group as early kidney scars can impact on renal function in later life. Pregnant women and the elderly should also take care, because UTIs can be more aggressive in these population segments.
Signs that a UTI Could Affect the Kidneys
When a UTI progresses and potentially involves the kidneys, symptoms can extend past burning or frequent urination. Fever and chills, severe pain in the side or back, nausea, vomiting, ongoing fatigue and swelling of the face or feet may occur. Foamy urine or decreased urine output can also indicate kidney stress.
When UTIs happen multiple times a year or are accompanied by these symptoms, you should not wait to be seen by a doctor.
Can UTI Kidney Damage Be Reversed?
Early treatment, if kidneys are involved, often can stop the damage and thus preserve some remaining kidney function. Kidney function could partially recover in certain instances. But after the marks are formed, reversing the degree is rarely possible. At that point compliance has to focus on prevention and effectively manage kidney health.
That’s why early diagnosis and follow-up after UTIs are critical.
How to Test Kidneys for Involvement of Doctors
Tests to diagnose recurrent UTIs Simple tests, such as a urine analysis and culture and blood tests to check that your kidneys are functioning correctly, are used to evaluate most cases of recurrent UTI. Blood pressure checks and imaging tests, such as ultrasound, also may be recommended to check for underlying causes or structural issues.
These tests are simple and can help detect kidney stress long before severe injury has taken place.
Caring for Your Kidneys if You Have Recurrent UTIs
Avoiding kidney damage starts with taking UTIs seriously. It is very important to take the full course of antibiotics that your doctor has prescribed for you, do your best not to become dehydrated. and avoid any self medicating. One more thing — controlling blood sugar and blood pressure also decreases kidney stress.
If UTIs continue to recur, finding and addressing the source of an infection is more crucial than constantly being put on antibiotics.
When to See a Specialist
When UTIs occur frequently, are severe or when there are abnormal kidney tests results a kidney specialist (nephrologist or urologist) should be seen. Prompt expert care can help avoid long-term complications and the potential for chronic kidney disease.
Conclusion
Although most UTIs are common and easily treatable, recurrent or untreated infections can silently damage the kidneys. UTIs are treatable with antibiotics, and kidney damage caused by UTIs is usually preventable if the infection is treated in a timely manner with prompt assessment and medical care.
If you do have recurrent urinary tract infections or general symptoms such as back pain that could indicate kidney involvement, seek the care of a specialist.
