RELATIONSHIP BETWEEN THE PREVALENCE OF UROLITHIASIS AND WATER QUALITY

Abstract

Background: Quality of drinking water affects the general metabolism, and especially in the occurrence of urological
diseases. Kidney stones mainly contain minerals, which usually depend on the water state.
Aim: to study the relationship between the epidemiology of urolithiasis and the state of drinking water in the Turkestan
oblast.
Methods: For the evaluation of the water quality physical, chemical and microbiological tests of water were performed in
two regions of Turkestan oblast: Saryagash region and Turkestan city. Secondary educational and higher educational
institutions, residential buildings, municipal public spheres, medical institutions and water supply sources were among the
objects of research. Protocols for the study of drinking water samples from centralized and non-centralized water supply No.
2020/00/00 were used. Statistical analyses were conducted using R Studio software (Integrated Development Environment,
Boston, USA).
Results: The main comparative differences were noted in pH, oxidizability and total hardness of the water, as well as in
the content of such minerals as residual, free and combined chlorine, ammonia nitrogen, nitrite and nitrate, chloride and
copper. In all these parameters, the content of indicators is higher in the drinking water of Turkestan city, which may indicate
a potential threat to the growth of urolithiasis in the regional centre. Microbiological data of both the city of Turkestan and the
Saryagash region comply with state standards.
Conclusion: The study results confirm the combined effect of differences in water physical and chemical parameters on
the prevalence of urolithiasis in the regions of the Turkestan oblast.
