Kidney stone formation is a multifactorial process that is associated with other disease processes. Insulin resistance plays a key role in type 2 diabetes mellitus (DM), and it has been linked to uric acid stone formation.1,2 Insulin resistance might result in a deficit in ammonium production in the kidney, which lowers urinary pH, thus generating a favorable milieu for uric acid stone formation.

Taylor and colleagues searched for a prospective association between DM and kidney stone formation by conducting a cross-sectional study of 3 large cohorts: Nurses’ Health Study I (older women), Nurses’ Health Study II (younger women), and the Health Professional Follow-up Study (men). At baseline, the multivariate relative risk of stone prevalence in those with DM was significant for all 3 cohorts. The prospective development of an incident kidney stone event was significantly greater in both female cohorts with DM but not in the male group. In addition, the multivariate risk of incident DM was significant in subjects with a history of kidney stones for all 3 cohorts.
These findings again demonstrate that stone formation might be linked to common systemic diseases. Similar associations have been previously demonstrated with hypertension.3,4
