Urinary Tract Infection (UTI)

Causes & Risk Factors

UTIs occur when bacteria enter and infect the urinary tract, with risk influenced by several factors:

•  Female anatomy — a shorter urethra makes bacterial entry more likely.

•  Sexual activity — can introduce bacteria into the urinary tract.

•  Urinary catheter use — significantly increases infection risk.

•  Diabetes — associated with increased UTI risk and susceptibility.

•  Urinary tract abnormalities affecting normal urine flow.

•  Pregnancy and menopause are both associated with increased UTI susceptibility due to physiological and hormonal changes.

Symptoms & When to Test

UTI symptoms depend partly on whether the infection is limited to the bladder or has spread to the kidneys.

•  Burning or pain during urination

•  Increased urinary frequency

•  Urgency

•  Lower abdominal discomfort

•  Cloudy or foul-smelling urine

•  Blood in urine

•  Fever or flank pain in more significant infections — suggestive of possible kidney involvement

When Should You Consider Testing?

Testing is generally appropriate for symptoms suggestive of a UTI, particularly for recurrent infections, complicated presentations, treatment failure, suspected antimicrobial resistance, selected cases in pregnancy, or in patients with significant underlying urinary disease.

Why Tests Are Combined

Urinalysis provides a rapid initial screen for leukocytes, nitrite, blood, and protein, which can support the clinical suspicion of UTI quickly, while urine culture identifies the specific causative organism and provides a more definitive diagnosis.

Antimicrobial susceptibility testing (AST), performed on the cultured organism, is particularly important in recurrent UTI, complicated UTI, treatment failure, suspected antimicrobial resistance, selected cases in pregnancy, or patients with significant underlying urinary disease — situations where knowing the exact effective antibiotic meaningfully changes management.

For straightforward, first-time infections, urinalysis alone may be sufficient to guide initial treatment, but the combination becomes increasingly valuable as the clinical situation becomes more complex.
