Abstract
BackgroundPost-micturition dribbling (PMD) is one of the most bothersome lower urinary tract symptoms (LUTS) in men. Researches on the PMD are very limited because no proper tool to evaluate PMD. This study was to assess the correlation between PMD and erectile dysfunction (ED) in middle-aged men with LUTS.Methods658 middle-aged men with LUTS were enrolled. Patients filled in international prostate symptom score (IPSS) and Hayllm PMD questionnaire (HPMDQ) that was made by authors. Prostate size, prostate specific antigen, uroflowmetry including Qmax & post voided residual urine, IPSS, and international index for erectile function-5 (IIEF-5) were also assessed.ResultsMen were classified as ED (388 patients) and non-ED (270 patients) groups. HPMDQ was inversely well correlated with IIEF-5 (r=-0.384, p<0.001). Prevalence of ED was related to PMD severity (p=0.001). Predictive accuracy of HPMDQ for ED was not superior to that of other LUTS (each p>0.05). However, incorporation of HPMDQ into IPSS increased predictive accuracy of LUTS for ED (60.3% ⋄73.1%).ConclusionsIn middle-aged men with LUTS, PMD was inversely well correlated with erectile function, and its severity was related with prevalence of ED.AppendixHallym Post-Micturition Dribbling Questionnaire (HPMDQ). “In the past month, how often have you experienced the involuntary loss of urine immediately after you finished passing urine?” 0: none, 1: one in 3 times, 2: two in 3 times, 3: always.
