[Genetic and environmental factors implicated in recurrent calcium lithiasis].

In this prospective study, we compared the frequency of some genetic and environmental factors possibly implicated in the occurrence of calcium stone disease. A group of 439 patients (258 males and 181 females) with one episode of calcium stone was compared to a group of 191 patients (131 males and 60 females) with recurrent calcium stone disease. Population with stones was also compared to control population (n = 78, 40 males and 38 females) matched to age.
