Which finding would most strongly indicate stress incontinence rather than urge?

• A. Leakage with coughing or physical activity
• B. Leakage preceded by urgent need to void
• C. Leakage of large amounts with urgent need to void
• D. Leakage only when bladder is full

Answer: (A)

Leakage with coughing or physical activity signals stress incontinence because this type occurs when activities that raise intra-abdominal pressure overwhelm the pelvic floor and urethral sphincter, causing urine to leak even if the bladder isn’t full. The key idea is leakage triggered by pressure from coughing, sneezing, laughing, or exercise, which points to a support/sphincter weakness rather than a sudden bladder contraction. In contrast, leakage that happens after an urgent need to void or with a strong, immediate urge indicates urge incontinence, where involuntary detrusor contraction leads to leakage. Leakage only when the bladder is full suggests other processes such as overflow or bladder outlet issues, not stress from abdominal pressure.
