A Urinary Tract Infection (UTI) is an infection affecting any portion of the urinary tract system, including the urethra (urethritis), bladder (cystitis), or kidneys (pyelonephritis). UTIs are most commonly caused by uropathogenic Escherichia coli (E. coli) bacteria entering the urethra.
Common Symptoms
- Dysuria: Painful, sharp burning sensation during urination.
- Pollakiuria & Urgency: Frequent, sudden, uncontrollable urge to urinate, often producing small amounts.
- Cloudy & Malodorous Urine: Turbid, cloudy, or foul-smelling urine; may contain visible blood (hematuria).
- Suprapubic & Pelvic Pain: Pressure or dull aching in lower abdomen and pelvis.
- Upper UTI / Pyelonephritis Signs: High fever, shaking chills, flank/back pain, nausea, and vomiting (indicates kidney involvement requiring prompt medical care).
Causes & Risk Factors
- Bacterial ascension into urethra (predominantly E. coli from intestinal tract).
- Female anatomy (shorter urethral length).
- Poor hygiene practices or improper wiping.
- Voluntary urinary retention ("holding urine" for long periods).
- Inadequate fluid intake and dehydration.
- Sexual activity or use of diaphragms/spermicides.
- Urinary tract obstructions (kidney stones, enlarged prostate).
Diagnosis & Clinical Evaluation
- Urinalysis (Dipstick & Microscopy): Checks for leukocyte esterase, nitrites, WBCs, and RBCs.
- Urine Culture & Sensitivity (C&S): Identifies exact bacterial strain and antibiotic susceptibility.
- Renal Ultrasound or CT scan: Performed for recurrent UTIs or suspected pyelonephritis/stones.
Treatment & Prevention Protocol
- Targeted Prescription Antibiotics: Nitrofurantoin, Trimethoprim-Sulfamethoxazole, or Fosfomycin for lower UTIs; Fluoroquinolones or Ceftriaxone for pyelonephritis.
- High Fluid Hydration: Drinking 2.5–3 liters of water daily to flush bacteria from the urinary tract.
- Urinary Analgesics: Phenazopyridine for rapid symptomatic relief of severe burning.
- Preventative Habits: Urinate immediately after intercourse, wipe from front to back, avoid holding urine, limit caffeine and alcohol bladder irritants, and consider cranberry extract supplements.
