Abstract

Purpose: Lower urinary tract symptoms (LUTS) are correlated with erectile dysfunction (ED), but research on whether postmicturition 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.
