Postmicturition Dribble Is Associated with Erectile Dysfunction in Middle-Aged and Older Men with Lower Urinary Tract Symptoms
Purpose: Lower urinary tract symptoms (LUTS) are correlated with erectile dysfunction (ED), but research on whether post-micturition dribble (PMD) is related to ED is limited. We assessed the correlation between PMD and ED in middle-aged and older Korean men with LUTS. Materials and Methods: In ou...

| Summary: | Purpose: Lower urinary tract symptoms (LUTS) are correlated with erectile dysfunction (ED), but research on whether post-micturition dribble (PMD) is related to ED is limited. We assessed the correlation between PMD and ED in middle-aged and older Korean men with LUTS.
Materials and Methods: In our prospective, cross-sectional, observational, multicenter study, we enrolled 205 men (age >40 years) with LUTS. LUTS and ED were assessed using the International Prostate Symptom Score (IPSS) and International Index of Erectile Function-5 (IIEF-5), respectively. PMD was assessed using the Hallym PostMicturition Dribble Questionnaire, Question 1, and the PMD volume was calculated in a paper test. Age, prostate volume, serum prostate-specific antigen, maximum urinary flow rate, and postvoid residual urine were also evaluated.
Results: There were significant differences in the total and voiding IPSS between men with and without ED (p=0.042 and 0.043, respectively). The Hallym PostMicturition Dribble Questionnaire 1 score was inversely well correlated with the IIEF-5 score (r=-0.388, p<0.001). Also, the PMD volume was inversely correlated with the IIEF-5 score (r=-0.138, p=0.042). ED prevalence increased as the Hallym PostMicturition Dribble Questionnaire 1 score increased (p=0.002). Further, incorporating the Hallym PostMicturition Dribble Questionnaire 1 into the IPSS tended to increase the predictive accuracy of LUTS by 4.2% in ED patients (p=0.082).
Conclusions: PMD was significantly correlated with ED and reinforced the relationship between LUTS and ED in middle-aged and older men. PMD might be an important component of the association between LUTS and ED. |
