Causes Of Kidney Infections
A kidney infection happens when bacteria infects your kidneys. The bacteria are usually a type called E. coli, which live in your bowel.
The bacteria get in through the opening of the urethra and move upwards through your urinary tract, first infecting your bladder and then your kidneys.
It’s thought the bacteria can get into your urinary tract by accidentally spreading from your anus to your urethra. This can happen if you wipe your bottom after going to the toilet and the soiled toilet paper comes into contact with your genitals. It can also happen during sex.
In rare cases, a kidney infection can develop if bacteria or fungi infect the skin and the infection spreads through your bloodstream into your kidney. However, this type of infection usually only occurs in people with weakened immune systems.
Can A Uti Be A Sign Of Cancer Or Other Problems
Dr. Rx
If you have more than three UTIs in a year, you should be evaluated by a urologist. When infections occur in rapid succession, it can be a sign of an underlying problem with bladder or kidney drainage. Sometimes, when no specific cause is found, a low dose daily preventive antibiotic is used to prevent infection over a period of months. Dr. Mindrup
The vast majority of UTIs are not a sign of a serious disease. Yet when they keep coming back, you should see a doctor. They will rule out other causes such as kidney stones, poor drainage of the kidney or bladder, or tumors, all of which are rare causes of UTI.
In rare instances, recurrent UTIs can lead to a life threatening condition called urosepsis or bladder cancer.
How Are Urinary Tract Infections Diagnosed
Your doctor will use the following tests to diagnose a urinary tract infection:
- Urinalysis: This test will examine the urine for red blood cells, white blood cells and bacteria. The number of white and red blood cells found in your urine can actually indicate an infection.
- Urine culture: A urine culture is used to determine the type of bacteria in your urine. This is an important test because it helps determine the appropriate treatment.
If your infection does not respond to treatment or if you keep getting infections over and over again, your doctor may use the following tests to examine your urinary tract for disease or injury:
- Ultrasound: In this test, sound waves create an image of the internal organs. This test is done on top of your skin, is painless and doesnt typically need any preparation.
- Cystoscopy: This test uses a special instrument fitted with a lens and a light source to see inside the bladder from the urethra.
- CT scan: Another imaging test, a CT scan is a type of X-ray that takes cross sections of the body . This test is much more precise than typical X-rays.

What Conditions Are Related To Recurrent Utis
Recurrent UTIs sometimes happen along with other conditions, such as:
- vesicoureteral reflux , which is found in 30%50% of kids diagnosed with a UTI. In this congenital condition, pee flows backward from the bladder to the ureters. Ureters are thin, tube-like structures that carry pee from the kidney to the bladder. Sometimes the pee backs up to the kidneys. If it’s infected with bacteria, it can lead to pyelonephritis.
- hydronephrosis, which is an enlargement of one or both kidneys due to backup or blockage of urine flow. It’s usually caused by severe VUR or a blocked ureter. Some kids with hydronephrosis might need to take daily low doses of antibiotics to prevent UTIs until the condition producing hydronephrosis gets better or is fixed through surgery.
But not all cases of recurrent UTIs can be traced back to these body structure-related problems. For example, dysfunctional voiding when a child doesn’t relax the muscles properly while peeing is a common cause of UTIs. Not peeing often enough also can also increase a child’s risk for recurrent infections. Both dysfunctional voiding and infrequent urination can be associated with constipation.
Rarely, unrelated conditions that harm the body’s natural defenses, such as diseases of the immune system, also can lead to recurrent UTIs. Use of a nonsterile urinary catheter can introduce bacteria into the urinary tract and also cause an infection.

In some cases, a kidney can lodge in a specific area in your kidney and cause discomfort. The pain a kidney stone causes can differ as it moves around in your kidney and down the ureter.

Sometimes bacteria spread from another part of the body through the bloodstream to the urinary tract. Urinary tract infection is less common in men than in women because the male urethra is long, making it difficult for bacteria to spread to the bladder.
Urinary tract infection may be caused by a sexually transmitted disease. Sometimes a stone in the urinary tract blocks the flow of urine and causes an infection. In older men, an enlarged prostate can cause a urinary tract infection by keeping urine from draining out of the bladder completely. Infection might also be caused by the use of a catheter used to drain the bladder or by urethral stricture, which is a narrowing of the urethra by scar tissue from previous infections or surgical procedures.
You may be more likely to have a UTI if you have diabetes or another medical problem that affects the immune system.

Your urinary tract is made up of your:
- Kidneys. These clean waste from your blood and make urine .
- Ureters. These thin tubes, one for each kidney, carry urine to your bladder.
- Bladder. This stores urine.
- Urethra. This tube carries urine from your bladder to outside your body.
If any of these parts gets germs in it, you can get a UTI. Most often, your bladder gets infected first. This can be painful but isnât usually serious.
But if the bad bacteria or viruses travel up your ureters, you can get a kidney infection. If left untreated, a kidney infection can cause life-threatening problems.

How Long Will The Effects Last
For most UTIs, the symptoms go away within 24 hours after you begin treatment. Take all of the medicine your healthcare provider prescribes, even after the symptoms go away. If you stop taking your medicine before the scheduled end of treatment, the infection may come back.
Without treatment, the infection can last a long time. If it is not treated, the infection can permanently damage the bladder and kidneys, or it may spread to the blood. If the infection spreads to the blood, it can be fatal.
When Treatment Doesnt Work
UTI is a fairly common illness, accounting for around 8.3 million doctor visits yearly in the United States alone. This is probably why most people just shrug it off as another harmless condition, and most of the time, theyre right not to worry. Generally, this genitourinary infection is non-complex and thus fairly easy to manage.
There are cases, however, when patients dont respond to the treatment. According to Erik Castle, MD, from Mayo Clinic, there are several factors that may predispose you to UTI, particularly if youre a woman. These are:
- kidney or bladder stones
- bacteria entering the urethra during intercourse
- changes in estrogen levels
- previous surgery on the urinary tract
- diabetes and other associated complications
- bladder cancer
In men, however, having an enlarged or infected prostate can exacerbate their UTI symptoms or predispose them to a chronic infection. Also, if you have other conditions requiring you to use a catheter, the chances of getting your urinary tract infected also increase.
