How is a urinary tract infection (UTI) treated?

UTI treatment depends on where the infection is located, how severe it is, and the patient's individual risk factors. Treatment may include antibiotics for bacterial infections, symptom-relief measures, adequate fluid intake, and treatment of an underlying problem such as urinary obstruction or stones. For systemic UTIs, prompt antimicrobial treatment and evaluation of any urinary obstruction or other underlying abnormality are important.

How is a simple bladder infection treated?

A localised bladder infection, also called cystitis, may be treated with an appropriate antimicrobial when antibiotic treatment is indicated.

The choice of treatment depends on factors such as:

• The suspected or identified bacteria
• Local antibiotic resistance patterns
• Previous urine culture results
• Medication allergies
• Other medical conditions
• Previous antibiotic use
• Whether the infection is recurrent

The 2026 EAU guidelines updated recommendations for antimicrobial therapy for cystitis and emphasise selecting treatment according to the individual clinical situation.

Do all UTIs require antibiotics?

Not necessarily. Treatment depends on the type of UTI and the individual patient.

For some non-geriatric women with acute cystitis, non-antibiotic approaches may be considered as an alternative to antibiotics through shared decision-making, although these approaches may involve a greater symptom burden and a slightly increased risk of complications such as kidney infection.

A suspected systemic UTI is different and generally requires prompt antimicrobial treatment.

What if the UTI has reached the kidneys?

A kidney infection, or pyelonephritis, is considered a systemic UTI. Patients may have urinary symptoms together with fever, chills, flank pain, nausea, vomiting, or significant illness.

Systemic UTIs require prompt assessment and antimicrobial treatment. The choice of treatment depends on the severity of illness, resistance risks, previous cultures, allergies and other patient-specific factors.

What happens if antibiotics do not work?

If symptoms persist or worsen despite treatment, the diagnosis and treatment should be reassessed.

A urine culture and antibiotic susceptibility testing may help determine whether the causative organism is resistant to the initial treatment. Doctors may also investigate whether an underlying problem—such as a urinary stone, obstruction or incomplete drainage of urine—is preventing recovery.

Why is treating the underlying cause important?

Some patients develop repeated UTIs because of an underlying urinary problem.

Conditions such as urinary stones, obstruction, enlarged prostate, urinary retention or other anatomical abnormalities may need to be addressed alongside infection treatment. The EAU guidelines specifically recommend identifying and managing relevant urological abnormalities in systemic UTI.

How can symptoms be managed during recovery?

Depending on the individual situation, supportive measures may include adequate fluid intake and appropriate symptom relief. However, these measures should not be considered a substitute for appropriate medical treatment when a bacterial infection requires antibiotics.

SCI International Hospital

At SCI International Hospital, Dr. Gautam Banga evaluates UTI treatment according to the type and severity of infection and the patient's individual urological condition. When appropriate, urine testing and culture can help guide antimicrobial selection.

For recurrent, persistent or complicated infections, the evaluation may also focus on underlying causes such as enlarged prostate, urinary stones, urethral stricture, obstruction or incomplete bladder emptying. Treating these contributing factors can be important for reducing repeated infections.
