目的确定日本下尿路结石年发病率和流行病学方面的变化和趋势。方法收集日本泌尿外科委员会批准的301家医院2015年泌尿科医生诊断为首次和复发性下尿路结石的患者数据。根据性别、年龄和结石成分估计的年发病率与1965年至2005年期间的全国调查进行了比较。结果日本下尿路结石的发病率从1965年的4.7/10万稳步上升至2015年的12.0/10万。然而，下尿路结石的年龄标准化年发病率在同一时期保持相对稳定，1965年和2015年分别为5.5/10万和6.0/10万。发病率的增加在≥ 80岁的人中最为明显。草酸钙结石的发病率在男性和女性中稳步上升，而在过去50年中，男性中感染相关结石的发病率从26.2%显著下降至14.3%。结论：在日本，全国范围的调查表明，下尿路结石的发病率在50年内稳步上升。这一趋势可能反映了人口老龄化的变化和日本医疗水平的提高。
Objectives To determine changes and trends in the annual incidence and epidemiological aspects of lower urinary tract stones in Japan. Methods Data about patients who had been diagnosed by urologists in 2015 with first and recurrent lower urinary tract stones were collected from 301 hospitals approved by the Japanese Board of Urology. The estimated annual incidence according to sex, age and stone composition was compared with previous nationwide surveys between 1965 and 2005. Results The incidence of lower urinary tract stones in Japan has steadily increased from 4.7 per 100 000 in 1965 to 12.0 per 100 000 in 2015. However, the age standardized annual incidence of lower urinary tract stones has remained relatively stable over the same period at 5.5 per 100 000 and 6.0 per 100 000 in 1965 and 2015, respectively. The increase in incidence was most evident among individuals aged >= 80 years. The incidence of calcium oxalate stones has steadily increased among males and females, whereas that of infection-related stones has significantly decreased from 26.2% to 14.3% among men over the past 50 years. Conclusions Nationwide surveys suggest a steady increase in the incidence of lower urinary tract stones over a 50-year period in Japan. This trend might reflect changes in the aging population and improved Japanese medical standards.
