552 Introduction. Urolithiasis is a widespread disease with high the frequency of recurrence. An important preventive measure is an increase in daily urine output. Patients with urolithiasis need to take into account the mineral the composition of the fluid consumed, since it can affect the formation of stones. It is especially important to pay attention to the composition of bottled water purchased in retail chains due to its significant differences.
Purpose. Analyze the composition of bottled water sold in retail chains of the Northwestern federal district (NWFD). Conduct a comparative analysis of the compositions carbonated and still water, as well as compare the composition of domestic and European bottled still water. Materials and methods. An independent laboratory determined the mineral composition of 36 samples of bottled water purchased in 2 retail chains of the NWFD. Done сomparison of the compositions of 19 samples of still and 16 samples of carbonated water. Comparison of the compositions of domestic and European non-carbonated bottled water.
Results. The data obtained by us on the mineral composition of the purchased water samples corresponded to the indicators declared by the manufacturers. Comparison of carbonated and still water showed no statistically significant differences in the content of calcium, sodium, magnesium, potassium, sulfates, hydrocarbons. Comparison of the mineral composition of domestic still and European still bottled water showed the presence of statistically significant differences in the content of calcium and hydrocarbonates, which were higher in the water of European manufacturers.
Conclusions. The mineral composition of bottled water can vary significantly. It is important for patients with urolithiasis to take into account the mineral composition of the water, which they consume, so it can influence the development of relapse.
