UTI Symptoms, Diagnosis & Treatment: What You Need to Know

A Urinary Tract Infection (UTI) is a bacterial infection of the urinary system (urethra, bladder, ureters, kidneys). It is not associated with white skin spots resembling vitiligo—that description is inaccurate. Typical UTI symptoms involve the urinary tract itself.

Classic UTI Symptoms

• Dysuria: Burning/pain during urination
• Frequency: Urinating often, small volumes
• Urgency: Sudden, strong need to void
• Suprapubic pain/pressure: Lower abdominal discomfort
• Urine changes: Cloudy, bloody (pink/red), strong/foul odor
• Systemic signs (if kidney involvement/pyelonephritis): Fever (>38°C/100.4°F), flank pain, chills, nausea/vomiting, confusion (elderly)

Risk Factors

• Female anatomy (short urethra)
• Sexual activity (new partner, frequency)
• Menopause (low estrogen → vaginal pH change)
• Urinary retention, catheters, stones, obstruction
• Diabetes, immunosuppression
• Prior UTIs, genetic predisposition

Diagnosis

1. Dipstick urinalysis: Leukocyte esterase, nitrites (rapid, office-based)
2. Microscopy: WBCs, bacteria, RBCs
3. Urine Culture: Gold standard; identifies organism & antibiotic sensitivities (essential for complicated/recurrent cases)

Treatment

• Uncomplicated Cystitis (women): 3-day Trimethoprim-Sulfamethoxazole (Bactrim), 5-day Nitrofurantoin (Macrobid), or single-dose Fosfomycin. Avoid fluoroquinolones for uncomplicated UTI.
• Complicated/Pyelonephritis: 7–14 days oral/IV antibiotics guided by culture.
• Recurrent UTIs (≥3/year or ≥2/6mo): Prophylaxis (postcoital or daily low-dose), vaginal estrogen (postmenopausal), behavioral measures.

Prevention (Evidence-Based)

• Adequate hydration (2–3 L/day)
• Void after intercourse
• Front-to-back wiping
• Avoid irritants (douches, spermicides)
• Vaginal estrogen (postmenopausal)
• Cranberry products: mixed evidence; may reduce adherence of E. coli

See a clinician if symptoms persist >48h on antibiotics, fever develops, flank pain, pregnancy, male, child, or recurrent infections.
