For a formal diagnosis, bladder diary should be kept for at least how many days?

• A. 1 day
• B. 3 days
• C. 7 days
• D. 14 days

Answer: (B)

Collecting a bladder diary over multiple days is needed because urinary patterns vary from day to day. Keeping it for at least three days gives enough data to reliably chart how often a person voids, the typical voided volumes, and how often leakage occurs, including episodes at night. One day is too variable to draw a solid diagnosis, while longer diaries (like seven or fourteen days) add detail but also burden; three days strikes a practical balance, capturing weekday and weekend patterns and providing a representative snapshot for formal assessment.
