Abstract

Objective:

Post-micturition dribble (PMD) is one of the post-micturition lower urinary tract symptoms (LUTS). Although there have been many studies of LUTS in Japanese men, PMD is not completely understood in the Japanese population. In the present study, we investigated the prevalence and bother of PMD in Japanese men.

Methods:

From 2007 to 2008, a cross-sectional community-based study on LUTS was conducted in Japanese men aged 40–79 years in Shimamaki-mura, Hokkaido, Japan. The prevalence and bother of PMD were investigated using a validated questionnaire, and prostate volume (PV) and the peak flow rate (Qmax) were measured.

Results:

The prevalence of PMD in men aged their 40s, 50s, 60s, and 70s was 13.6%, 39.0%, 44.2%, and 41.2%, respectively. PMD was not rare compared with other LUTS. The degree and bother of PMD were statistically correlated (r = 0.558, P < .001), suggesting that the presence of PMD impairs quality of life. There was no significant relationship between the prevalence of PMD and PV or Qmax.

Conclusions:

PMD is not rare compared with other LUTS. The presence of PMD impairs quality of life.
