PE 03. The relationship between lower urinary tract symptoms (LUTS) and premature ejaculation (PE) in Korean men

Objective: To evaluate the correlation between lower urinary tract symptoms (LUTS), erectile dysfunction (ED) and premature ejaculation (PE) in Korean men aged more than 40 years old.

Design and Methods: A total of 258 men aged more than 40 years old were enrolled by questionnaires which were composed of International Prostate Symptom Score (IPSS: storage symptoms [ST], voiding symptoms [VD]), 5-item version of the International Index of Erectile Function (IIEF-5) and Premature Ejaculation Diagnostic Tools (PEDT). Comparative analysis was done to examine the relationship between LUTS and PE.

Results: A total of 258 male ranging in age from 40 to 79 years completed the questionnaires and were included in the assessment. 40-49 years old men were 8, 50-59 years old men were 47, 60-69 years old men were 191, 70-79 years old men were 12. Prevalence of PE by criteria of PEDT was 29.1 percent, and PE to be judged by them was 49.5 percent. There were no significant correlation of the scores of the IPSS and PEDT with age but were significant relationship between IIEF-5 score and age. PEDT score was positive coefficient correlation to IPSSSD (r=0.326, P<0.001), IPSS-VD (r=0.183, P=0.005) and IPSS-Total (r=0.310, P<0.001). PEDT score was correlated to IPSS-SD more than IPSS-VD. In particularly, PEDT score was significantly negative coefficient correlation to IIEF-5 total score (r=–0.248, P=0.004). IIEF-5 total score was not shown significant coefficient correlation to IPPS-SD (r=–0.199, P=0.068), IPSS-VD (r=–0.158, P=0.372) and IPSS-Total (r= -0.221, P=0.149). However, IIFF-5 total score had tendency to be negatively correlated to IPSS-SD more than IPSS-VD.

Conclusions: LUTS, especially storage symptoms may have negative impact on men with PE. In elderly men, control of both ED and LUTS play an important role in management of PE.
