Introduction

The prevalence of kidney stones has been increasing in the US and Europe, with stone-related emergency attendances and procedures consequently increasing, producing a significant economic impact on hospital emergency and elective services. There is sparse available literature regarding recent incidence trends of urolithiasis in the UK. As implications for workforce planning, centralisation of stone services and the potential for identifying the highest ‘risk’ become increasingly relevant and we hypothesized there may be ‘hot spots’ of stone occurrence which could prompt further epidemiological research and help plan local stone services.

Methods

Hospital Episode Statistics (HES) datasets and Office for National Statistics Mid-year population estimates and census data were used to calculate the occurrence of Urolithiasis England from 2003-2014. Information regarding age, gender, ethnicity, Index of Multiple Deprivation (IMD) decile and local authority district of residence were obtained. Tableau software was used to visually graph our data analysis.

Results

The prevalence of urolithiasis in England grew by 33.7% over the study period. The LA with the greatest increase was South Cambridgeshire which showed a compound annual growth rate of 14.06% and absolute growth of 272.7%. In contrast, the prevalence of urolithiasis decreased in 46 of 326 local authorities, with Mid Suffolk showing a compound annual growth rate of -6.07% and an absolute decrease of 46.5%. Regional grouping of LA’s was also geographically mapped._x000D_ _x000D_ An increase in the absolute growth occurred in all age categories except 0-4 years. The age group 85+ shows the greatest growth throughout the study period, with absolute growth of 106.6% and an annual compound rate of growth of 7.35%. As seen in figure [1] the 75-84 age group continued to trend upwards over the study period while the 15-44 age group stabilised from 2010 between 14.23 and 15.30 per 10,000. _x000D_ Prevalence in men and women has increased from 16.6 & 7.06 per 10,000 to 20.84 & 10.74 respectively. Men showed an absolute growth of 25.1%, and women an absolute growth of 52.1%_x000D_

Conclusions

Our work confirms the increasing prevalence of kidney stones in England, and demonstrates this prevalence is varied depending on area of residence and age. 'Hot spots' of stone activity exist, and scope for further epidemiological analysis exists.
