To evaluate renal colic frequency in different seasons and around full moon.
A total of 1481 patients with renal colic were studied retrospectively addressing days of a month both in solar and lunar calendar.
The mean age of the patients was 57 ± 13 years. Total admissions in summer was 613; of which 288 (41%), 199 (39%), and 126 (43%) were in years 2002, 2003, and 2004, respectively. The highest frequencies in solar calendar were on days 2 (56), 20 (63), and 27 (59) and the lowest were on days 6 (36), 22 (38), 26 (34), and 31 (31). We did not find any statistically significant association according to solar calendar (P = .3). In lunar calendar, most of the admissions were on day 15 (69) and the lowest rates were on days 1 (25) and 30 (26), which was statistically significant (P = .04).
Renal colic frequency is not correlated with solar calendar, but its highest frequency in lunar calendar is in the middle of the month period. Although we found a correlation between full moon effect and renal tide, but this is a new window for further studies.
评估不同季节及满月前后肾绞痛的发生频率。
对1481例肾绞痛患者进行回顾性研究，涉及阳历和阴历每月的日期。
患者的平均年龄为57±13岁。夏季总入院人数为613例；其中2002年、2003年和2004年分别为288例（41%）、199例（39%）和126例（43%）。阳历中发生频率最高的日期为第2天（56例）、第20天（63例）和第27天（59例），最低的日期为第6天（36例）、第22天（38例）、第26天（34例）和第31天（31例）。根据阳历我们未发现任何具有统计学意义的关联（P = 0.3）。在阴历中，大多数入院病例发生在第15天（69例），发生率最低的日期为第1天（25例）和第30天（26例），具有统计学意义（P = 0.04）。
肾绞痛发生频率与阳历无关，但其在阴历中的最高频率出现在月中。尽管我们发现满月效应与肾潮之间存在关联，但这是一个有待进一步研究的心领域。
