title: Correlation between lower urinary tract symptoms and premature ejaculation in Korean men older than 40 years old [corrected].
abstract: OBJECTIVE
  To evaluate the correlation between lower urinary tract symptoms (LUTS) and premature ejaculation (PE) in Korean men older than 40 years.
  
  
  METHODS
  In total, 258 men older than 40 years completed the International Prostate Symptom Score (IPSS; total score, storage symptoms [ST], and voiding symptoms [VD]), a 5-item version of the International Index of Erectile Function (IIEF-5), and the Premature Ejaculation Diagnostic Tool (PEDT). The study examined the relationship between LUTS and PE. In the PEDT, PE is defined as a score ≥11.
  
  
  RESULTS
  The prevalence of PE was 29.1% with the PEDT versus a self-reported value of 49.5%. The prevalence of PE was 30.9% in 40 to 59-year-old men (21.3%) and 28.1% in 60 to 79 year-old men (78.7%). In men 40 to 59 and 60 to 79 years old, the mean PEDT, IPSS, and IIEF-5 scores were 8.65 and 7.88, 13.5 and 12.38, and 15.83 and 13.69, respectively. No significant correlations were observed between the total and subscale scores of the IPSS (p=0.204) and the PEDT (p=0.309) with increasing age, whereas a significant negative correlation was detected between the IIEF-5 and age (p=0.002). The PEDT score was significantly correlated with the IPSS-ST (r=0.326, p<0.001), IPSS-VD (r=0.183, p=0.005), IPSS-total (r=0.310, p<0.001), and IIEF-5 total (r=-0.248, p<0.001).
  
  
  CONCLUSIONS
  LUTS, especially storage symptoms, were related to PE. In elderly men, control of both erectile dysfunction and LUTS may play an important role in managing PE.
