The impact of ambient temperature on the incidence of urolithiasis: a systematic review and meta-analysis

Objective This review aimed to confirm the association between ambient temperature and incidence of urolithiasis and evaluate the impact thereof. Methods A systematic literature review was performed up to September 2019 using multiple databases. The effect of temperature on urolithiasis risk was assessed using risk ratio (RR). Pearson correlation coefficient (Pearson’s r) was used to evaluate the linear association between ambient tempe rature and urolithiasis incidence. The non-linear association between climatic temperature and the urolithiasis incidence was also evaluated. Results Twenty-four studies related to the temperature and urolithiasis risk in 14 different countries or regions of five continent involving over 2.5 mill ion cases were included in the meta-analysis. High climatic or workplace temperature was a significant risk factor of urolithiasis. The weighted correlation coefficient (Pearson’s r) of monthly temperature and urolithiasis risk was 0.49 [95% confidence interval (CI) 0.40–0.57], a moderate correl ation (0.4
