What is Urinary Tract Infection (UTI)?

Causes of Urinary Tract Infections

Anything that reduces your bladder emptying or irritates the urinary tract can lead to Urinary Tract Infections. There are also many factors that can put you at an increased risk of a getting a Urinary Tract Infections. These factors include:

  • kidney stones
  • a previous Urinary Tract Infections urinary tract obstructions or blockages, such as an enlarged prostate, kidney stones, and certain forms of cancer
  • prolonged use of urinary catheters, which may make it easier for bacteria to get into your bladder
  • age — older adults are more likely to get Urinary Tract Infections
  • reduced mobility after surgery or prolonged bed rest
  • diabetes, especially if poorly controlled, which may make it more likely for you to get a Urinary Tract Infection
  • pregnancy
  • abnormally developed urinary structures from birth
  • a weakened immune system

Symptoms of Urinary Tract Infection

Symptoms of a  Urinary Tract Infection depend on what part of the urinary tract is infected.

Lower tract Urinary Tract Infection affect the urethra and bladder. Symptoms of a lower tract Urinary Tract Infection  include:

  • urine that looks like cola or tea
  • burning with urination
  • increased frequency of urination without passing much urine
    • increased urgency of urination
  • urine that has a strong odor
  • pelvic pain in women
  • rectal pain in men
  • bloody urine
  • cloudy urine

Upper tract Urinary Tract Infection affect the kidneys. These can be potentially life threatening if bacteria move from the infected kidney into the blood. This condition, called urosepsis, can cause dangerously low blood pressure, shock, and death.

Symptoms of an upper tract Urinary Tract Infection include:

  • pain and tenderness in the upper back and sides
  • chills
  • fever
  • nausea
  • vomiting

Symptoms Of  Urinary Tract Infection in Men

Symptoms of an upper tract urinary infection in men are similar to those in women. Symptoms of a lower tract urinary infection in men sometimes includes rectal pain in addition to the common symptoms shared by both men and women.

Symptoms of Urinary Tract Infection in women

Women with a lower tract urinary infection may experience pelvic pain. This is in addition to the other common symptoms. Symptoms of upper tract infections among both men and women are similar.

Treatment of Urinary Tract Infection

In some cases, viruses or fungi are the causes. Viral Urinary Tract Infections are treated with medications called antivirals. Often, the antiviral cidofovir is the choice to treat viral Urinary Tract Infections. Fungal Urinary Tract Infections are treated with medications called antifungals.

Untreated Urinary Tract Infections

It’s important to treat a UTI — the earlier, the better. Untreated UTIs become more and more severe the further they spread. A UTI is usually easiest to treat in the lower urinary tract. An infection that spreads to the upper urinary tract is much more difficult to treat and is more likely to spread into your blood, causing sepsis. This is a life-threatening event.

If you suspect that you have a UTI, contact your doctor as soon as possible. A simple examination and urine or blood test could save you a lot of trouble in the long run.

Antibiotics for a Urinary Tract Infections

The form of antibiotic used to treat a bacterial UTI usually depends on what part of the tract is involved. Lower tract UTIs can usually be treated with oral antibiotics. Upper tract UTIs require intravenous antibiotics. These antibiotics are put directly into your veins.

Sometimes, bacteria develop resistance to antibiotics. Results from your urine culture can help your doctor select an antibiotic treatment that will work best against the type of bacteria that’s causing your infection.

Treatments other than antibiotics for bacterial UTIs are being examined. At some point, Urinary Tract Infections treatment without antibiotics may be an option for bacterial UTIs by using cell chemistry to change the interaction between the body and the bacteria.

Diagnosis for Urinary Tract Infections

If you suspect that you have a UTI based on your symptoms, contact your doctor. Your doctor will review your symptoms and perform a physical examination. To confirm a diagnosis of a UTI, your doctor will need to test your urine for microbes.

The urine sample that you give your doctor needs to be a “clean catch” sample. This means the urine sample is collected at the middle of your urinary stream, rather than at the beginning. This helps to avoid collecting the bacteria or yeast from your skin, which can contaminate the sample. Your doctor will explain to you how to get a clean catch.

When testing the sample, your doctor will look for a large number of white blood cells in your urine. This can indicate an infection. Your doctor will also do a urine culture to test for bacteria or fungi. The culture can help identify the cause of the infection. It can also help your doctor choose which treatment is right for you.

If a virus is suspected, special testing may need to be performed. Viruses are rare causes of UTIs but can be seen in people who have had organ transplants or who have other conditions that weaken their immune system.

Upper tract Urinary Tract Infections

If your doctor suspects that you have an upper tract UTI, they may also need to do a complete blood count (CBC) and blood cultures, in addition to the urine test. A blood culture can make certain that your infection hasn’t spread to your blood stream.

Recurrent Urinary Tract Infections

If you have recurrent UTIs, your doctor may also want to check for any abnormalities or obstructions in your urinary tract. Some tests for this include:

  • An ultrasound, in which a device called a transducer is passed over your abdomen. The transducer uses ultrasound waves to create an image of your urinary tract organs that are displayed on a monitor.
  • An intravenous pyelogram (IVP), which involves injecting a dye into your body that travels through your urinary tract and taking an X-ray of your abdomen. The dye highlights your urinary tract on the X-ray image.
  • A cystoscopy, which uses a small camera that’s inserted through your urethra and up into your bladder to see inside your bladder. During a cystoscopy, your doctor may remove a small piece of bladder tissue and test it to rule out bladder inflammation or cancer as a cause of your symptoms.
  • A computerized tomography (CT) scan to get more detailed images of your urinary system.

 Risk factors for Urinary Tract Infections in Men

Most Urinary Tract Infections risk factors for men are the same as those for women. However, having an enlarged prostate is one risk factor for a Urinary Tract Infections that’s unique to men.

Risk factors for Urinary Tract Infections in Women

There are additional risk factors for women. Some factors that were once believed to be a cause of Urinary Tract Infections in women have since been shown to not be as important, such as poor bathroom hygiene. Recent studies have failed to show that wiping from back to front after going to the bathroom leads to Urinary Tract Infections in women, like previously believed.

In some cases, certain lifestyle changes may help lessen the risk of some of these factors.

Spermicides

Spermicides may increase UTI risk. They can cause skin irritation in some women. This increases the risk of bacteria entering the bladder.

Condom use during sex

Non-lubricated latex condoms may increase friction and irritate the skin of women during sexual intercourse. This may increase the risk of a UTI.

However, condoms are important for reducing the spread of sexually transmitted infections. To help prevent friction and skin irritation from condoms, be sure to use enough water-based lubricant, and use it often during intercourse.

Shorter urethra

The length and location of the urethra in women increases the likelihood of UTIs. The urethra in women is very close to both the vagina and the anus. Bacteria that may naturally occur around both the vagina and anus can lead to infection in the urethra and the rest of the urinary tract.

A woman’s urethra is also shorter than a man’s, and the bacteria have a shorter distance to travel to enter the bladder.

Sexual intercourse

Pressure on the female urinary tract during sexual intercourse can move bacteria from around the anus into the bladder. Most women have bacteria in their urine after intercourse. However, the body can usually get rid of these bacteria within 24 hours. Bowel bacteria may have properties that allow them to stick to the bladder.

Diaphragms

Diaphragms may put pressure on a woman’s urethra. This can decrease bladder emptying.

Decrease in estrogen levels

After menopause, a decrease in your estrogen level changes the normal bacteria in your vagina. This can increase the risk of a UTI.

Prevention of Urinary Tract Infections:

Everyone can take the following steps to help prevent Urinary Tract Infections:

  • Drink six to eight glasses of water daily.
  • Don’t hold urine for long periods of time.
  • Talk to your doctor about managing any urinary incontinence or difficulties fully emptying your bladder.

However, Urinary Tract Infections happen much more frequently in women than in men. The ratio is 8:1. This means that for every eight women who have Urinary Tract Infections, only one man does.

Certain steps may help prevent Urinary Tract Infections in women. For postmenopausal women, using topical estrogen prescribed by your doctor could make a difference in preventing Urinary Tract Infections. If your doctor believes that intercourse is a factor of your recurrent Urinary Tract Infections, they may recommend taking preventive antibiotics after intercourse, or long-term. Some studies have shown that long-term preventive use of antibiotics in older adults reduced the risk of Urinary Tract Infections.

Taking daily cranberry supplements or using vaginal probiotics, like lactobacillus, may also help in the prevention of Urinary Tract Infections. Some studies suggest that using probiotic vaginal suppositories can decrease the occurrence and recurrence of Urinary Tract Infections, by changing the bacteria found in the vagina.
