However, little is known about the effect of SES on nephrolithiasis. We seek to investigate the relationship between poverty level and income on stone composition and 24-hour urine composition. METHODS: A retrospective review was performed on patients presenting to a single tertiary-level urology center with a history of nephrolithiasis over a one-year period. Patient demographics, medical characteristics, 24-hour urine characteristics and stone analysis were included in our analysis. Poverty level (percentage of individuals below poverty level) and median household income for each postal address was obtained from the U.S. Census Bureau data. Wilcoxon Rank sum, Kruskal-Wallis test and Pearson correlation coefficients were used to compare outcomes. RESULTS: A total of 439 patients were included in the analysis. Median poverty level was 6% (IQR = 3.8%) and median household income was $97,583 (IQR = $28,811). There is a significant association between type of stone and household income. Patients with uric acid stone have a significantly lower median income when compared to those with calcium oxalate stone ($85913 compared to $97682, p-value = 0.0140). There is a significant positive correlation between 24-hour urine volume and median income (r = 0.097, p = 0.042), and a significant negative correlation between 24-hour urine volume and poverty level (r = -0.098, p = 0.038). CONCLUSIONS: Increasing poverty level and decreasing household income were associated with decreased urinary volume. Decreased urinary volume is a risk factor for kidney impairment and kidney stone formation. Physicians should be aware of this potential disparity when counseling patients.
