To investigate the prevalence and correlates of postmicturition urinary incontinence in Japanese men, and to compare with those of other types of urinary incontinence.Methods:
A total of 3224 male participants in a community-based survey were investigated. Three types of urinary incontinence were assessed; that is, postmicturition urinary incontinence, stress urinary incontinence and urge urinary incontinence. Age, body mass index, alcohol intake, cigarette smoking, and medical history of 18 diseases and conditions were the dependent variables for candidate correlates of the three types of incontinence.Results:
Unlike stress urinary incontinence and urge urinary incontinence, the prevalence of postmicturition urinary incontinence was constant throughout all generations (6.5% for the 30 s, 6.6% for the 40 s, 6.0% for the 50 s, 6.3% for the 60 s and 5.1% for the 70 s). The independent correlates for postmicturition urinary incontinence were asthma (P < 0.001; odds ratio 3.01), prostatic disease (P < 0.001; odds ratio 2.38), rhinosinusitis (P = 0.001; odds ratio 1.92), low back pain (P = 0.003; odds ratio 1.58), sleeplessness (P = 0.013; odds ratio 1.86), depression (P = 0.024; odds ratio 3.41) and body mass index (P = 0.025; odds ratio 0.73).Conclusions:
Postmicturition urinary incontinence has different characteristics from those of stress urinary incontinence and urge urinary incontinence. Unlike stress urinary incontinence and urge urinary incontinence, postmicturition urinary incontinence is not age-dependent. Several diseases related to an allergic status, such as asthma and rhinosinusitis, are correlates for postmicturition urinary incontinence.
