Which statement best describes the relationship between urge incontinence and overactive bladder?

• A. They are unrelated
• B. Urge incontinence is always caused by detrusor underactivity
• C. They are different names for the same condition
• D. Overactive bladder often coexists with urge incontinence

Answer: (D)

The relationship being tested is that overactive bladder is a broader syndrome that often includes urge incontinence as part of its presentation. Overactive bladder is defined by urinary urgency, typically with increased daytime frequency and sometimes nocturia, and it can involve leakage when the urge is strong. Urge incontinence is specifically the leakage that occurs in response to a sudden, strong urge. Because the underlying issue in overactive bladder is detrusor overactivity or heightened urgency, many patients experience leakage as part of this pattern. So, overactive bladder often coexists with urge incontinence because leakage is a common, but not universal, feature of the urgency and frequency that define the syndrome. The other ideas—that they are unrelated, that urge incontinence is always caused by detrusor underactivity, or that they are simply different names for the same condition—don’t fit the typical clinical relationship.
