Urinary Tract Infection: Symptoms and Treatment

Urinary Tract Infection: Symptoms and Treatment

Urinary tract infection (UTI) is one of the most common bacterial infections affecting people of all ages, though it is particularly prevalent in women. While often dismissed as a minor inconvenience, an untreated UTI can escalate into a serious kidney infection. Understanding the symptoms and knowing when to seek treatment is essential. At V-Cure Hospital in Chennai, our urology and general medicine teams provide prompt and effective UTI care.

What Is a Urinary Tract Infection (UTI)?

A UTI is an infection in any part of the urinary system — including the kidneys, ureters, bladder, and urethra. Most infections involve the lower urinary tract (bladder and urethra). The infection is most commonly caused by bacteria, with Escherichia coli (E. coli) being responsible for approximately 80–85% of cases.

Types of UTIs

• Cystitis (bladder infection): The most common type, causing pain, pressure, and frequent urination
• Urethritis (urethra infection): Burning during urination is the primary symptom
• Pyelonephritis (kidney infection): A more serious UTI involving the kidneys, with fever, back pain, and nausea

Symptoms of a Urinary Tract Infection

• Burning or painful urination (dysuria): A stinging, burning sensation while passing urine — the hallmark symptom of a UTI
• Frequent and urgent need to urinate: Feeling the need to urinate often, even when the bladder is not full
• Passing only small amounts of urine: Despite the urge, you may only pass a small amount each time
• Cloudy, dark, or strong-smelling urine: Urine may appear murky or have an unpleasant odour
• Blood in urine (haematuria): Urine may appear pink, red, or cola-coloured
• Pelvic or lower abdominal pain: Particularly in women, pressure or discomfort in the lower abdomen is common
• Fever and chills: These symptoms suggest the infection may have reached the kidneys — seek immediate medical attention
• Back or flank pain: Kidney infections cause pain in the upper back or sides
• Nausea and vomiting: Associated with kidney infections or severe cases

Who Is at Risk of UTIs?

• Women: Due to a shorter urethra, bacteria reach the bladder more easily
• Sexually active individuals: Sexual activity introduces bacteria into the urinary tract
• Post-menopausal women: Hormonal changes affect urinary tract defences
• People with diabetes: High blood sugar weakens the immune system
• Those with urinary catheters: Catheters can introduce bacteria into the bladder
• Individuals with kidney stones or structural abnormalities
• Men with prostate problems: Enlarged prostate can obstruct urine flow, increasing risk

Diagnosis

Our specialists at V-Cure Hospital will perform the following to confirm a UTI:

• Urine analysis (urinalysis): Checks for white blood cells, red blood cells, and bacteria
• Urine culture and sensitivity: Identifies the specific bacteria and the most effective antibiotic
• Ultrasound or CT scan: Recommended for recurrent UTIs to rule out structural issues or kidney stones
• Cystoscopy: Used in complex or recurrent cases to directly view the bladder

Treatment of UTIs

Antibiotic Therapy

UTIs are treated with antibiotics. The type, dosage, and duration depend on the severity and the specific bacteria identified:

• Uncomplicated bladder infections: Typically a 3–7 day antibiotic course
• Kidney infections: Longer antibiotic courses (10–14 days), sometimes requiring IV antibiotics
• Always complete the full antibiotic course even if symptoms improve early

Pain Relief

Urinary analgesics may be prescribed to relieve the burning and discomfort while antibiotics take effect.

Supportive Care

• Drink plenty of water to flush bacteria from the urinary tract
• Avoid caffeine, alcohol, and spicy foods that irritate the bladder
• Apply a warm heating pad to the abdomen for comfort

Preventing UTIs

• Stay well hydrated — aim for 8–10 glasses of water daily
• Urinate after sexual intercourse
• Wipe from front to back after using the toilet (women)
• Avoid harsh soaps or douches in the genital area
• Wear cotton underwear and avoid tight clothing
• Don't hold urine for long periods
• Consider probiotics to maintain healthy urinary flora

When to Seek Immediate Care

See a doctor immediately if you experience high fever, severe back or flank pain, nausea/vomiting, or signs of confusion — these may indicate a kidney infection (pyelonephritis) requiring urgent treatment.
