List common signs of acute urinary retention in a male patient with BPH.

• A. Inability to void, weak urine stream, hesitancy
• B. Urinary urgency with urge incontinence
• C. Inability to void, weak urine stream, hesitancy, suprapubic fullness/distention
• D. No symptoms

Answer: (C)

Acute urinary retention from BPH shows a bladder that cannot empty despite the urge to void, producing several telltale signs: inability to void, a weak urine stream, and hesitancy when trying to urinate, along with bladder distention felt as suprapubic fullness. The obstruction from enlarged prostate prevents normal outflow, causing the bladder to become acutely distended and painful or uncomfortable. This combination is what distinguishes acute retention from other urinary symptoms. Urgency with urge incontinence describes leakage with a sudden urge, which is a different issue and not the pattern seen with acute retention. No symptoms would be incorrect because retention typically presents with noticeable difficulty urinating and a distended bladder.
