Seasonal variations of urine volume and urinary excretion of calcium, oxalate, magnesium and phosphate were studied in 118 men with urolithiasis on a standard mineral diet and on free diet. The 24-hour urine volume did not vary by season. There was no significant seasonal variation in the excretion of urinary calcium, oxalate, magnesium or phosphate on a standard mineral diet. While on a free diet the patients' urinary excretion of calcium showed statistically significant seasonal differences between age groups. The seasonal variations in the excretion of urinary oxalate and phosphate were statistically significant on free diet, but did not differ by age. The urinary excretion of magnesium was not affected by season nor age. Dietary intake probably best explains seasonal changes in the urinary excretion of calcium, oxalate and phosphate.
对118名患有尿路结石的男性进行了研究，观察他们在标准矿物质饮食和自由饮食情况下，尿量以及钙、草酸盐、镁和磷酸盐的尿排泄量的季节性变化。24小时尿量没有季节性变化。在标准矿物质饮食情况下，尿钙、草酸盐、镁或磷酸盐的排泄量没有显著的季节性变化。在自由饮食情况下，患者尿钙排泄量在不同年龄组之间存在统计学上的显著季节性差异。在自由饮食情况下，草酸和磷酸盐排泄量的季节性变化具有统计学意义，但不受年龄影响。镁的尿排泄量不受季节和年龄的影响。饮食摄入可能是解释钙、草酸盐和磷酸盐尿排泄量季节性变化的最佳原因。
