下尿路症状男性人群勃起功能调查

Erectile dysfunction in men with lower urinary tract symptoms

目的：了解下尿路症状（LUTS）男性人群的勃起功能障碍（ED）患病情况，探讨LUTS与ED之间的相关性。方法：2011年11月～2012年8月，抽取1000例40～80岁、有固定性伴侣的男性人群，采用国际前列腺症状评分（IPSS）及国际勃起功能指数（IIEF-5）评估LUTS和ED的严重程度，单因素Logistic回归分析LUTS与ED的相关性。结果：40～80岁男性人群的LUTS患病率为42．81％（426／995），ED患病率为76．18％（758／995）。其中426例有LUTS症状患者的ED患病率为82．16％（350／426），569例无LUTS症状的ED患病率为71．70％（408／569）。随着LUTS严重程度的增高，ED的患病率明显升高。Logistic回归分析显示，年龄、LUTS严重程度与ED的关联存在统计学显著意义（P〈0．01）。结论：LUTS患者存在很高的ED发生率。年龄越大，LUTS症状愈严重者患ED的风险更高。

Objective： To investigate the incidence of erectile dysfunction （ED） in men with lower urinary tract symptoms （LUTS） and the correlation between LUTS and ED. Methods ： We enrolled 1 000 men aged 40 - 80 years with regular sex partners, evaluated their erectile function using IIEF-5, and investigated LUTS among them by International PrOstate Symptom Score （IPSS）. We studied the relationship between ED and LUTS by univariate conditional Logistic regression analysis. Results： LUTS were found in 42.81% of the men investigated （426/995）, and ED in 76. 18% of the subjects （758/995） and 82.16% of those with LUTS （350/426）. Logistic regression analysis revealed a significant relation of ED with aging and LUTS （ P 〈 0.01 ）. Conclusion ： The incidence of ED is high in men with LUTS and increases with aging and the severity of LUTS.
