Between July 1, 1980 and August 1984, 222 patients (112 men and 112 women) were referred to the Nephrology out-patient clinic of a hospital serving a population of about 250,000. Urolithiasis was revealed by renal colics in 71% of the cases; 64 patients (29%) had been suffering from one or several attacks of renal colic before the study period. The first clinical symptoms appeared between the ages of 20 and 59 years in over 80% of the cases, with a peak of incidence between 30 and 39 years. Calcium stone lithiasis was as frequent in women as in men; the sex ratio was around 1 whatever the patient's age at the onset of the disease; 65% of patients had hypercalciuria on an unrestricted diet. The annual incidence of urolithiasis (hospital cases) was 15.6 for 100,000 inhabitants, and the theoretical prevalence (distribution of new patients aged about 50) 0.8 for 100 inhabitants. These epidemiological data compared with those in the literature, show a relatively low incidence of urolithiasis, notably among men, in that particular region of France.
1980年7月1日至1984年8月期间，222名患者（112名男性和112名女性）被转诊至一家服务人口约25万的医院的肾脏病门诊。71%的病例通过肾绞痛发现患有尿石症；64名患者（29%）在研究期之前曾遭受过一次或几次肾绞痛发作。超过80%的病例首次临床症状出现在20至59岁之间，发病高峰在30至39岁之间。钙结石性尿石症在女性和男性中发病率相同；无论发病时患者年龄如何，性别比均约为1；65%的患者在非限制饮食情况下有高钙尿症。尿石症（住院病例）的年发病率为每10万居民15.6例，理论患病率（约50岁新患者的分布）为每100居民0.8例。这些流行病学数据与文献中的数据相比，表明在法国那个特定地区，尿石症的发病率相对较低，尤其是在男性中。
