老年男性勃起功能及迟发性性腺功能减退症状与下尿路症状严重性的关系

本文旨在研究土耳其爱琴海地区的老年男性下尿路症状（LUTSs）、勃起功能障碍（ED）和有症状的迟发性性腺功能减退症（SLOH）三者间的关系。符合以下标准的500名男性患者被纳入该研究：40周岁以上;过去6个月内有稳定的性关系;在六个泌尿外科诊所之一进行过就诊登记。每位患者均行血清PSA、睾酮水平及尿流率的检测,并填写国际前列腺症状评分和生活质量评分（IPSS-QoL）量表、国际勃起功能指数（IIEF）问卷和老年男性症状（AMS）量表。在所有的研究对象中,23．9％的患者有轻度LUTSs,53．3％有中度LUTSS,22．8％有重度LUTSS。每组间总睾酮水平无明显差异。除此之外,69．6％的病人患有ED,且ED的发生率与LUTS严重性呈正相关。71．2％的患者出现SLOH（AMS〉27）,且IPSS评分越高,严重的性腺功能减退症状的发生率也越高。相关性分析显示以上三种问卷分数之间有显著关联。总之,LUTS严重性是ED和SLOH的非年龄依赖性危险因素,LUTS严重性和SLOH症状之间似乎有显著的相关性,但还需要从病因学和生物学角度进行深入阐明。

Erectile function and late-onset hypogonadism symptoms related to lower urinary tract symptom severity in elderly men

The aim of this study was to evaluate the relationship between lower urinary tract symptoms （LUTSs）, erectile dysfunction （ED） and symptomatic late-onset hypogonadism （SLOH） in ageing men in the Aegean region of Turkey. Five hundred consecutive patients 〉40 years old who had been in a steady sexual relationship for the past 6 months and were admitted to one of six urology clinics were included in the study. Serum prostate-specific antigen and testosterone levels and urinary flow rates were measured. All patients filled out the International Prostate Symptom Score and Quality of Life （IPSS-QoL）, International Index of Erectile Function （IIEF） and Aging Males＇ Symptoms （AMS） scale forms. Of the patients, 23.9% had mild LUTSs, 53.3% had moderate LUTSs and 22.8% had severe LUTSs. The total testosterone level did not differ between groups. Additionally, 69.6% had ED. The presence of impotence increased with increasing LUTS severity. Symptomatic late-onset hypogonadism （AMS 〉27） was observed in 71.2% of the patients. The prevalence of severe hypogonadism symptoms increased with the IPSS scores. A correlation analysis revealed that all three questionnaire scores were significantly correlated. In conclusion, LUTS severity is an age-independent risk factor for ED and SLOH. LUTS severity and SLOH symptoms appear to have a strong link that requires etiological and biological clarification in future studies.
