Which scenario most strongly suggests overflow incontinence?

• A. Leakage that occurs with coughing or sneezing
• B. Frequent leakage with weak, intermittent stream and high residuals
• C. Leakage only when bladder is full after long periods
• D. Leakage after caffeine intake

Answer: (B)

Overflow incontinence happens when the bladder can’t empty properly, so urine keeps accumulating and eventually leaks as pressure builds. It’s usually due to a weak detrusor muscle or an obstruction at the outlet, which leads to a high post-void residual volume. The hallmark signs are a weak, intermittent urinary stream and the sense that the bladder isn’t emptying well, along with frequent urination and sometimes nocturia, with leakage or dribbling from the bladder that’s overfilled. This scenario—frequent leakage together with a weak, intermittent stream and high residuals—maps directly to that pattern, indicating the bladder is not empting fully and is overflowing. In contrast, leakage with coughing or sneezing points to stress incontinence from pelvic floor weakness, leakage only when the bladder is full after long periods suggests a different pattern (often overdistention or urge-related issues), and leakage after caffeine is typically due to bladder overactivity causing urge incontinence.
