Urinary Tract Infections (UTIs): Symptoms, Diagnosis, Treatment and Prevention Tips

A urinary tract infection occurs when microorganisms, most commonly bacteria, enter and multiply within the urinary tract. Depending on the location of the infection, it may involve:

• Urethra – urethritis
• Bladder – cystitis
• Kidneys – pyelonephritis

UTI symptoms can develop quickly and may vary depending on which part of the urinary tract is affected. Common symptoms include:

A burning sensation, discomfort or pain while passing urine, known as dysuria, is one of the common symptoms associated with a UTI.

You may feel the need to urinate more frequently than usual, even when only a small amount of urine is passed.

A sudden and difficult-to-control urge to urinate can occur with a bladder infection.

Some people may notice blood in their urine, known medically as hematuria. Blood in the urine should not automatically be assumed to be caused by a UTI and may require medical evaluation.

Fever, chills or sudden rigors can be signs of a more significant infection. When urinary symptoms occur together with fever or chills, particularly with back or side pain, kidney involvement should be considered and medical attention should be sought promptly.

A lower urinary tract infection can sometimes spread upward through the urinary system and affect the kidneys. A kidney infection, or pyelonephritis, may cause symptoms such as:

• High fever
• Chills or rigors
• Pain in the back or side
• Nausea or vomiting
• Significant weakness or feeling unwell

A doctor may recommend different tests depending on your symptoms, age, medical history and suspected location of the infection.

A urine routine examination can help identify findings such as:

• Pus cells
• Blood
• Bacteria
• Other abnormalities

A urine culture can identify the bacteria responsible for an infection and may help guide the choice of an appropriate antibiotic. The decision to perform a urine culture depends on the clinical situation.

An ultrasound of the urinary system may be recommended when a doctor suspects an obstruction, urinary stone, structural abnormality or another underlying problem. Additional investigations may be required depending on the patient's symptoms and medical history.

UTIs are less common in otherwise healthy men than in women. Therefore, when a man develops a UTI, a doctor may consider whether there is an underlying factor contributing to the infection. Possible factors can include urinary obstruction, prostate-related problems, urinary stones or other abnormalities. A urologist may recommend a more detailed evaluation when appropriate rather than treating recurrent infections without investigating the underlying cause.

People with poorly controlled diabetes may have an increased risk of infections, including urinary tract infections. Elevated blood glucose levels can affect the body's ability to fight infections and may contribute to an environment in which microorganisms can grow. People with diabetes should therefore follow their healthcare professional's recommendations for:

• Blood glucose management
• Regular medical check-ups
• Appropriate treatment of infections
• Monitoring of related health conditions

Treatment depends on the cause, severity, location of the infection and individual patient factors. When a bacterial UTI is diagnosed or strongly suspected, a doctor may prescribe an appropriate antibiotic. However, antibiotics should not be self-prescribed or taken unnecessarily. The appropriate medicine, dose and duration should be determined by a qualified healthcare professional. For recurrent, complicated or unusual infections, the doctor may also investigate whether an underlying condition is contributing to the problem. If a patient develops symptoms suggesting kidney involvement, such as significant fever, chills, vomiting or severe back/side pain, prompt medical assessment is important.

Simple everyday habits can support urinary health and may help reduce the risk of some urinary infections.

Drink adequate fluids throughout the day according to your individual health needs. Regular bladder emptying may help reduce the time bacteria remain in the urinary tract. People with certain heart, kidney or other medical conditions may have specific fluid restrictions, so individual medical advice should take priority.

Maintaining healthy bowel habits is important for overall urinary health. Chronic constipation can affect bladder function and may contribute to urinary problems in some individuals. A balanced diet, adequate fibre and appropriate fluid intake can support healthy bowel habits.

Good personal hygiene can help reduce the risk of bacterial contamination. Keep the genital and surrounding areas clean and follow appropriate hygiene practices. For recurrent UTIs, however, hygiene alone may not address the underlying cause. A medical evaluation may be necessary.

You should consider consulting a urologist if you experience:

• Repeated UTIs
• Burning or pain while urinating that persists
• Blood in the urine
• Difficulty passing urine
• Recurrent urinary urgency or frequency
• Fever or chills associated with urinary symptoms
• Back or side pain with urinary symptoms
• UTI symptoms in a male patient
• Urinary symptoms along with diabetes
• Symptoms that do not improve with prescribed treatment
