Prevalence and Risk Factors of Postmicturition Dribble in Men

Purpose: We investigated postmicturition dribble (PMD) prevalence rates and risk factors in men. Materials and Methods: This cross-sectional study included 1037 men aged 31–86 years who participated in a male health survey. PMD was defined by involuntary urine loss immediately after urine was passed and was scaled from 0 to 5, depending on symptom severity. A score of ≥3 was considered significant PMD. PMD prevalence was also determined by age group, and logistic regression analyses were performed to identify risk factors. Results: The mean age of participants was 55.3 ± 8.9 years. Overall, 232 (22.4%) reported significant PMD. PMD prevalence significantly increased with age (P = 0.013): it was 18.2%, 17.2%, 20.8%, 28.7%, and 30.1% in men aged 30–39, 40–49, 50–59, 60–69, and ≥70 years old, respectively. Univariate analyses revealed that age, peak flow rate (Qmax), and prostate specific antigen levels were associated with significant PMD, while in multivariate analyses, only decreased Qmax was an independent risk factor. Conclusion: PMD was identified as a common condition in men across all age groups, and its prevalence significantly increased with age. The condition correlated more with voiding symptoms when compared with storage symptoms, and was associated with decreased Qmax.
