Which type of urinary incontinence results from an inability to completely empty the bladder?

• A. Urge Incontinence
• B. Functional Incontinence
• C. Overflow Incontinence
• D. Mixed Incontinence

Answer: (C)

The main idea is recognizing that this type of leakage comes from the bladder not emptying fully. When the detrusor muscle can’t contract adequately or there’s an obstruction at the outlet, the bladder becomes overdistended and urine leaks as pressure builds. This is overflow incontinence. In this pattern, you often see signs like a weak stream, hesitancy, frequency, and sometimes continuous dribbling, with a high residual amount of urine remaining after voiding. Older adults commonly develop it from conditions like benign prostatic hypertrophy or neurogenic problems, medications that reduce bladder contractility, or other causes that block complete emptying. The key feature is the coexistence of retention (incomplete emptying) with leakage. By contrast, urge incontinence involves leakage due to a sudden, overactive bladder detrusor that contracts inappropriately; functional incontinence results from nonbladder factors like mobility or cognitive issues preventing bathroom access; mixed involves more than one type. The essence here is the failure to empty the bladder completely leading to overflow.
