Involuntary leakage of urine. Types include: stress, urge, overflow, and functional.

• A. Urinary incontinence
• B. Urinary frequency
• C. Polyuria
• D. Perineum

Answer: (A)

Involuntary leakage of urine is called urinary incontinence. The four listed subtypes—stress, urge, overflow, and functional incontinence—are the common ways this condition presents, reflecting different underlying mechanisms that all result in leakage. Recognizing the umbrella term helps distinguish this from related but different ideas: urinary frequency describes needing to urinate often; polyuria is producing abnormally large amounts of urine; and the perineum is simply the anatomical region, not a condition.
