In the LUTS spectrum for BPH, which of the following is not a storage symptom?

• A. Frequency
• B. Nocturia
• C. Weak stream
• D. Urgency

Answer: (C)

The question tests the distinction between storage symptoms and voiding symptoms in lower urinary tract symptoms (LUTS) from BPH. Storage symptoms are those tied to filling and urge: more frequent urination, waking at night to urinate, and a sudden urge to void. These reflect bladder overactivity or reduced capacity while filling. Voiding symptoms come from trouble during emptying: a weak stream, hesitancy, straining, and sometimes incomplete emptying, all related to outflow obstruction.

A weak stream is a classic voiding symptom—it's about how effectively urine flows during urination, which is impaired by the obstruction from BPH. The other three—frequency, nocturia, and urgency—are storage symptoms because they relate to bladder filling and urgency to void. So weak stream is not a storage symptom.
