Which urinary symptom is most suggestive of a lower urinary tract infection?

• A. Hematuria Alone
• B. Dysuria, Urgency, and Frequency
• C. Itching at the Urethra
• D. Severe Flank Pain

Answer: (B)

Lower urinary tract infections produce irritation of the bladder and urethra, leading to irritative voiding symptoms. The most characteristic signs are dysuria (painful or burning during urination), urgency (a sudden need to urinate), and frequency (urinating more often). When these three together are present, they strongly point to inflammation of the lower tract rather than elsewhere.

Hematuria can occur with infections but isn’t as specific for a lower tract issue. Itching at the urethra suggests irritation or another condition like dermatitis or a yeast infection. Severe flank pain points to involvement of the upper urinary tract (kidneys) or stones, not the lower tract. So the combination of dysuria, urgency, and frequency best indicates a lower urinary tract infection.
