No sensation of bladder fullness is a symptom of urinary retention.

• A. No sensation of bladder fullness
• B. Increased urgency to urinate
• C. Burning lower abdominal pain
• D. Sleep-related issues

Answer: (A)

The concept here is how urinary retention can involve altered perception of bladder fullness. When the bladder fills but the normal sensory signals are blunted or long-standing distension has occurred, a person may not feel the usual sensation of fullness. That lack of awareness can be a feature of urinary retention, especially in cases of neurogenic bladder or chronic retention, where the urge to void isn’t felt even though the bladder is full.

This makes no sensation of bladder fullness the best choice because it directly reflects how sensation can be diminished in retention. Increased urgency to urinate is more about a strong need to void, which isn’t the defining sign of retention once the urge is overpowering or the bladder is under pressure. Burning lower abdominal pain points toward infection or inflammation rather than the retention pattern. Sleep-related issues are nonspecific and not a primary indicator of retention.
