背景资料：据报道，结石病具有明显的地理变异性，部分原因是年平均温度（MAT）以及气候条件的季节性波动。因此，肾绞痛的急诊（艾德）就诊高峰在夏季是常见的。材料和方法：本研究的目的是评估日复一日的气候变化对艾德（帕尔马市，北方意大利，温带大陆性气候）肾绞痛就诊次数的影响。在3286天（2002年1月至2010年12月）期间，从数据库中检索到共计10，802例绞痛发作。结果如下：对数据的分析证实，肾绞痛病例在夏季达到高峰，特别是在7月（每天最多4.1例肾绞痛病例），冬季最低点（2月每天最少2.7例肾绞痛病例）。线性回归分析显示，每日肾绞痛的平均病例数与每日平均温度（正相关，R = 0.93; p < 0.0001）和每日平均湿度（负相关，R =-0.82; p < 0.0001）之间存在高度显著的相关性。温度和湿度对肾绞痛病例发生率的影响在不同年龄组之间差异很大，30 - 40岁患者的发病率最高，70岁患者的发病率最低<20 and >。结论：综合数据表明，炎热和干燥的气候有利于加速结石形成的过程，这在老年人中似乎更为明显。
Background: A marked geographic variability has been reported in stone disease, partially attributed to the Mean Annual Temperature (MAT), as well as to the seasonal fluctuations of climatic conditions. Accordingly, peaks in Emergency Department (ED) visits for renal colic are commonplace during the summer. Materials and methods: The aim of this study was to assess the influence of day-by-day climate changes on the number of visits as a result of renal colic in the ED (City of Parma, northern Italy, temperate continental climate). A total of 10,802 colic episodes were retrieved from the database during a period of 3286 days (January 2002 to December 2010). Results: The analysis of the data confirms a peak of renal colic cases during the summer, especially in July (maximum number of 4.1 cases of renal colic per day), and a winter nadir (minimum number of 2.7 cases of renal colic per day, in February). The linear regression analysis shows a high and significant correlation between the mean number of cases of renal colic per day and both the mean daily temperature (positive association, R = 0.93; p < 0.0001) and the mean daily humidity (negative association, R = −0.82; p < 0.0001). The influence of temperature and humidity on the incidence of renal colic cases varied widely among age groups, the highest incidence seen in patients aged between 30 and 40 years, and the lowest seen for those aged <20 and >70 years of age. Conclusion: The combined data suggest that the hot and dry climate would favor an acceleration of the process of stone formation, which seems more pronounced in the older population.
