URINARY TRACT INFECTIONS (UTI)
URINARY TRACT INFECTIONS (UTI)
Author: Dr Saiful Hassan, MBBS, DEM, General Physician, HCL Healthcare
Urinary tract infection is an infection in any part of your urinary system — Kidneys, Ureters, Bladder and Urethra. Most infections involve the lower urinary tract — the bladder and the urethra.
Women are at greater risk of developing a UTI than are men. Infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a UTI spreads to kidneys.
Cause: Urinary tract infections typically occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. Although the urinary system is designed to keep out such microscopic invaders, these defenses sometimes fail. When that happens, bacteria may take hold and grow into a full-blown infection in the urinary tract.
Risk Factors in Females:
- Female anatomy.A woman has a shorter urethra than a man does, which shortens the distance that bacteria must travel to reach the bladder.
- Sexual activity.Sexually active women tend to have more UTIs than do women who aren’t sexually active. Having a new sexual partner also increases your risk.
- Certain types of birth control.Women who use diaphragms for birth control may be at higher risk, as well as women who use spermicidal agents.
- After menopause, a decline in circulating estrogen causes changes in the urinary tract that make you more vulnerable to infection.
- Urinary tract abnormalities. Babies born with urinary tract abnormalities that don’t allow urine to leave the body normally or cause urine to back up in the urethra have an increased risk of UTIs.
- Blockages in the urinary tract. Kidney stones or an enlarged prostate can trap urine in the bladder and increase the risk of UTIs.
- A suppressed immune system. Diabetes and other diseases that impair the immune system — the body’s defense against germs — can increase the risk of UTIs.
- Catheter use. People who can’t urinate on their own and use a tube (catheter) to urinate have an increased risk of UTIs. This may include people who are hospitalized, people with neurological problems that make it difficult to control their ability to urinate and people who are paralyzed.
- A recent urinary procedure. Urinary surgery or an exam of your urinary tract that involves medical instruments can both increase your risk of developing a urinary tract infection.
When is a UTI suspected:
Urinary tract infections don’t always cause signs and symptoms, but when they do they may include:
- Fever with chills
- Lower abdominal pain
- Nausea and vomiting
- A strong, persistent urge to urinate
- A burning sensation when urinating
- Passing frequent, small amounts of urine and strong-smelling urine
- Urine that appears cloudy, Urine that appears red, bright pink or cola-colored — a sign of blood in the urine
- Pain in the flanks or Pelvic pain, in women — especially in the center of the pelvis and around the area of the pubic bone.
When treated promptly and properly, lower urinary tract infections rarely lead to complications. But left untreated, a urinary tract infection can have serious consequences.
Complications of a UTI may include:
- Recurrent infections, especially in women who experience two or more UTIs in a six-month period or four or more within a year.
- Permanent kidney damage from an acute or chronic kidney infection (pyelonephritis) due to an untreated UTI.
- Increased risk in pregnant women of delivering low birth weight or premature infants.
- Urethral narrowing (stricture) in men from recurrent urethritis, previously seen with gonococcal urethritis.
- Sepsis, a potentially life-threatening complication of an infection, especially if the infection works its way up your urinary tract to your kidneys.
Investigations for diagnosis:
The doctor will advise for Urine Routine analysis or Urine Culture for detection of bacteria, in addition, Complete Blood Count (CBC) and other higher investigations like Ultrasound, Intravenous pyelogram, Cystoscopy, CT scan may be done as per your doctor advice.
Based on the signs and symptoms and the lab investigation reports, the doctor will prescribe medicines to relieve the symptoms and Antibiotics are prescribed to clear the bacteria. The treatment may vary from 5-7 days.
Prevention: You can take these steps to reduce your risk of urinary tract infections:
- Drink plenty of liquids, especially water.Drinking water helps dilute your urine and ensures that you will urinate more frequently — allowing bacteria to be flushed from your urinary tract before an infection can begin.
- Drink cranberry juice.Although studies are not conclusive that cranberry juice prevents UTIs, it is likely not harmful.
- Maintain good personal hygiene, especially of the genital area. Wipe from front to back.Doing so after urinating and after a bowel movement helps prevent bacteria in the anal region from spreading to the vagina and urethra.
- Empty your bladder soon after intercourse.Also, drink a full glass of water to help flush bacteria.
- Avoid potentially irritating feminine products.Using deodorant sprays or other feminine products, such as douches and powders, in the genital area can irritate the urethra.
- Change your birth control method. Diaphragms, or unlubricated or spermicide-treated condoms, can all contribute to bacterial growth.
