Urinary Tract Infection

Urinary Tract Infections (UTIs) are common bacterial infections that affect any part of the urinary system, including the kidneys, ureters, bladder, and urethra. Most UTIs involve the lower urinary tract, particularly the bladder (cystitis) and urethra (urethritis). They are more prevalent in women due to shorter urethras and proximity to the anus. Common symptoms include dysuria, frequency, urgency, suprapubic pain, and cloudy or strong-smelling urine. Escherichia coli is the most frequent causative organism. Risk factors include sexual activity, menopause, urinary retention, catheter use, and underlying urological abnormalities. Diagnosis is typically based on clinical presentation and urinalysis, with urine culture confirming the diagnosis and guiding antibiotic selection. Treatment involves targeted antibiotics, with short-course regimens often sufficient for uncomplicated cases. Recurrent UTIs may require further evaluation and prophylactic measures. Prompt treatment prevents complications such as pyelonephritis and sepsis.
