Urinary Tract Infection (UTI)
Urinary tract infections do not always have signs and symptoms, however when they appear, they may include:
- A strong, persistent urge to urinate
- A burning sensation when urinating
- Passing frequent, small amounts of urine
- Urine that appears cloudy
- Urine that appears pinkish — a sign of blood in the urine
- Strong-smelling urine
- Pelvic pain (in women) — especially in the center of the pelvis and around the area of the pubic bone
Urinary tract infections are common in women and many women experience more than one infection during their lifetime. Risk factors specific to women for UTIs include:
- 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 or having a new sexual partner increases your risk.
- Certain types of birth control. Women who use diaphragms and spermicidal agents may be at higher risk.
- Menopause. After menopause, a decline in circulating estrogen causes changes in the urinary tract and reduces its ability to resist bacteria invasion.
- A recent urinary procedure. Urinary surgery or an exam of your urinary tract that involves medical instruments can increase your risk.
In males, UTI can develop due to urinary tract abnormalities, blockages in the urinary tract due to kidney stones or an enlarged prostate, which traps urine in the bladder.
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 antibiotic to use.
- Those with repeated infections may need to undergo additional tests such as an ultrasound, cystoscopy or CT scan.
Mild cases may disappear spontaneously without treatment. However, because of the risk of the infection spreading to the kidneys, antibiotics are usually recommended. Prompt treatment is recommended for the elderly due to the high mortality rate in this group.
- As the source of the bacteria often comes from one’s own bowel, wipe yourself from the front to back to avoid faecal contamination of the urinary tract (especially during an episode of diarrhoea) after going to the toilet.
- Avoid potentially irritating vaginal deodorants and bubble baths and maintain a high standard of personal hygiene. This involves washing the genital area with water while showering and especially after intercourse. Voiding soon after intercourse is also encouraged.
- Any vaginal/ lower genital tract infection should be treated. Otherwise, the infection may spread to the urinary tract.
- For healthy individuals, it is recommended to drink a minimum fluid intake of 2 litres a day (more if exercising strenuously or on hot days).
- Regular and complete bladder emptying is advisable to prevent the accumulation of infected urine in the bladder.
