A survey of Japanese adult women was performed to clarify the status of urinary incontinence treatment, correlation between vaginal pressure and urinary incontinence, and awareness and implementation of pelvic floor muscle training exercises. Anonymous self-administered questionnaires together with vaginal pressure measurement were conducted from March 2010 to July 2012 for the 88 participants recruited from a hospital.Based on the survey results, 13 participants(14.8%)were classified as having urinary incontinence and another 33(37.5%)as having a history of urinary incontinence, and 42(47.7%)reported having no urinary incontinence. Among the 13 women reporting urinary incontinence, one was undergoing treatment, two had a treatment history, and 10 had no treatment history. Among those with no history of treatment for urinary incontinence, 50% had a mean onset period of >7 years, which indicated that many women had neglected urinary incontinence for a long time. Among the enrolled participants, 65.9% were aware of pelvic floor muscle training exercises, but only few were regularly performing or had performed these exercises. To examine the association between vaginal pressure and urinary incontinence, maximum contraction pressure, mean contraction pressure, and duration of contraction of the three groups were compared. The group with no urinary incontinence showed the highest values in all items, however, no significant differences were observed among the groups and vaginal pressure levels in all the groups varied widely.The above results highlight the importance of accurate knowledge of women’s urinary incontinence treatment to avoid negligence that could aggravate the condition. In addition, increasing vaginal pressure is not necessarily required for women’s urinary continence, but conscious contraction of the pelvic floor muscles at the time of increased abdominal pressure or just before having the urge to urinate is considered to be more important.
