Nephrolithiasis is increasing in developed and developing countries at an alarming rate. With the global spike in kidney stone diseases, it is crucial to determine what risk factors are influencing the current global landscape for kidney stones. Our aims for this review are: to identity and analyze the four categories of risk factors in contributing to the global scale of stone formation: lifestyle, genetics, diet, and environment; and discuss preventative measures for kidney stone formation. We also performed data search through the published scientific literature, i.e., PubMed® and found that there is a significant link between lifestyle and obesity with cases of calcium stones. Food and Agriculture Organization of the United Nations and World Health Organization factor indicators for dietary intake and obesity, along with climate data were used to create the projected total risk world map model for nephrolithiasis risk. Complete global analyses of nephrolithiasis deplete of generalizations is nearly insurmountable due to limited sources of medical and demographic information, but we hope this review can provide further elucidation into confounding risk factors and preventative measures for global nephrolithiasis analysis.
Core tip: We analyzed diet, lifestyle, genetics, and environment, four categorical risk factors that play major roles in the contribution of nephrolithiasis. Calcium stones and lifestyle factor obesity had a significant link; dietary factor of high protein and low intake of negative regulators increased the risk; and environmental factor of climate had a relatively high correlation to nephrolithiasis. Together, a model was formed to map a prevalence of nephrolithiasis of the world.
