The last three questions ask about storage symptoms: "During the past month or so, how often have you found it difficult to postpone urination?"; "During the past month or so, how often have you had to urinate again less than two hours after you finished urinating?"; and "Over the past month, how many times per night did you most typically get up to urinate from the time you went to bed at night until the time you got up in the morning?".
