Which description best fits stress incontinence in the context of decreased bladder outlet resistance?

• A. Leakage with overflow due to poor detrusor contraction
• B. Leakage with coughing or sneezing due to decreased outlet resistance
• C. Leakage with urge due to detrusor overactivity
• D. Leakage with prolonged bladder retention and urine volume

Answer: (B)

Stress incontinence happens when the outlet that keeps urine in the bladder isn’t strong enough to hold urine during increases in abdominal pressure. When you cough or sneeze, the sudden rise in pressure pushes urine through the weaker urethral outlet, so leakage occurs with these activities. That’s why leakage with coughing or sneezing best describes stress incontinence in the context of decreased bladder outlet resistance. Leakage with overflow due to poor detrusor contraction isn’t driven by pressure changes from the abdomen; it’s related to the bladder not emptying well because the detrusor muscle isn’t contracting effectively, leading to leakage as the bladder overflows. Leakage with urge due to detrusor overactivity is a different pattern where strong, involuntary bladder contractions drive the leakage. Leakage with prolonged bladder retention and urine volume suggests an inability to empty the bladder or a chronically full bladder, not leakage triggered by increased abdominal pressure.
