ABSTRACT
Objective: To compare the prevalence of Renal Colic [RC] in Ramadan [the month of fasting for Moslems] with other months of the lunar year
Material and Methods: Records of 574 subjects, who were admitted in the two medical centers of Varamin [a city in a hot region of Iran], were reviewed in order to estimate the time trend of RC
Results: This study included 398 males [69.3%] and 176 females [30.7%]. Twenty-seven males [62.8%] and 16 females [37.2%] were admitted in Ramadan; and 371 males [69.9%] and 160 females [30.1%] in other months [p<0.4] of the year. RCs were more common in June [68 patients, 11.8%], July [65 patients, 11.3%] and November [60 patients, 10.5%]. Forty-three subjects [7.5%] admitted in Ramadan; the frequency was not significantly different from mean admission of the year [48.3 +/- 17 patients]. There was also no significant difference between frequency of admissions in Ramadan and mean admission during cold half of the year [36.8 +/- 18.34 patients, p = 0.3]. Mean admission [64.4 +/- 3.3 patients] in warm seasons were significantly higher than Ramadan [p < 0.001]
Conclusion: Lack of difference in the two groups indicates that higher temperature rather than fasting as a cause for RCs
