The occurrence of stress incontinence with symptomatic urinary urgency is called?

• A. Overflow incontinence
• B. Mixed incontinence
• C. Functional incontinence
• D. Total incontinence

Answer: (B)

Mixed urinary incontinence is when leakage results from more than one mechanism, specifically both stress and urge components. Stress incontinence causes leakage with activities that raise intra-abdominal pressure (coughing, sneezing, lifting) due to pelvic floor weakness or urethral sphincter deficiency. Urge incontinence involves leakage accompanied by a sudden, urgent need to void, often from detrusor overactivity. When a patient has leakage with physical effort plus symptomatic urinary urgency, both mechanisms are present, defining mixed incontinence. This differs from overflow incontinence (continuous leakage from chronic retention), functional incontinence (leakage due to inability to reach the toilet), and total incontinence (continuous leakage without dry periods).
