Urinary Tract Infection: Symptoms, Causes, Diagnosis & Treatments
Written by Medicover Team and Medically Reviewed by Dr G Gokul Nachiketh , Urologist
Urinary tract infections (UTIs) are common infections that affect any part of the urinary system, including the kidneys, ureters, bladder, and urethra. Most UTIs involve the lower urinary tract, like the bladder and urethra. If left untreated, UTIs can lead to kidney infections and serious complications. Early detection and treatment are essential for recovery and prevention.
What are the Urinary Tract Infection Symptoms and Warning Signs?
Urinary tract infection symptoms can vary based on which part of the urinary system is infected. Early detection is essential to avoid complications. Symptoms commonly include painful urination, frequent urges to urinate, and cloudy or strong-smelling urine. In more severe cases, fever, nausea, and lower back pain may be present.
Common Symptoms
- Frequent urge to urinate
- Burning sensation while urinating
- Cloudy urine
- Strong-smelling urine
- Blood in urine
- Pelvic discomfort
Severe Symptoms
What are the Different Types of Urinary Tract Infections?
UTIs can affect different parts of the urinary system, and each type presents unique symptoms. Identifying the specific type helps in choosing the most effective treatment.
- Cystitis: A bladder infection that causes pelvic pain, frequent urination, and discomfort.
- Urethritis: Infection of the urethra resulting in burning while urinating and discharge.
- Pyelonephritis: A kidney infection that can cause back pain, high fever, nausea, and chills.
UTIs in children or during pregnancy may present differently and require specialized care.
What are the Common Causes and Risk Factors of Urinary Tract Infection?
Understanding the causes of UTIs is crucial for effective prevention. Bacterial infections, particularly those caused by E. coli, are the most common cause. Poor hygiene, dehydration, catheter use, and sexual activity can also contribute.
Causes
- Bacterial infection (most commonly E. coli)
- Poor hygiene practices
- Sexual activity
- Urinary retention due to stones or obstruction
- Use of catheters
- Weakened immune system
- Hormonal changes during pregnancy or menopause
Risk Factors
- Previous history of UTIs
- Diabetes
- Pregnancy
- Kidney stones
- Age (children and the elderly are more vulnerable)
- Vaginal flora changes
- Urinary tract surgeries

Get Second OpinionHow is Urinary Tract Infection Diagnosed?
UTIs are diagnosed using a combination of physical symptoms and laboratory testing. Doctors may perform a urinalysis to detect bacteria and white blood cells, or a urine culture to identify the specific bacteria. In complex or recurring cases, imaging tests such as ultrasound or CT scans help identify underlying urinary issues.
Diagnostic Methods
- Urinalysis: Identifies signs of infection in the urine.
- Urine Culture: Determines the type of bacteria.
- Ultrasound: Detects abnormalities in urinary organs.
- Cystoscopy: Examines the bladder with a scope.
- CT Scan: Offers detailed imaging to locate complications.
What are the Treatment Options for Urinary Tract Infections?
Treatment for UTIs depends on the cause and the severity of the infection. Mild cases often respond to oral antibiotics, while more severe infections may require intravenous medication. Pain relief medications can ease discomfort. Staying hydrated and following the full antibiotic course are critical.
First-line Treatments
- Trimethoprim-sulfamethoxazole
- Nitrofurantoin
- Fosfomycin
- Cephalexin
- Ciprofloxacin (for complicated UTIs)
Symptom Relief
- Phenazopyridine (to relieve discomfort)
Additional Care
- Increased fluid intake
- Follow-up testing to confirm infection clearance
For recurrent or complex urinary tract infections (UTIs), consult a urologist at Medicover.
