Calcium oxalate renal stones are more common in affluent countries.

Their aim was to establish whether the occurrence of renal stones varied between towns in Britain according to social and economic conditions. The influence of diet, physical activity, water hardness, temperature and ultra violet light upon the occurrence of renal stones was also examined. The annual incidence rate of renal stone patients referred to hospital (both as in-patients and out-patients) was measured in 18 towns in England and Wales. For men aged 15-64 there was a marked variation in annual incidence, ranging from 145 per 100,000 in Canterbury to 31 in Burton-upon-Trent. The incidence of renal stones was associated with the proportion of the town population in social classes I and II (p<0.01) and an overall index of social and economic conditions - there being a higher rate in towns with `better
