Dear Editor,I have two comments on the interesting case report by Pichandi and Raamya on an 8-year-old female child with silicateurolithiasis.[1]First, the authors mentioned that there were no associated risk factors for silicate stone in any form in the studied child.[1] I presume that the following risk factor ought to be seriously considered. In India, ground water is being used as raw water for 85% public water supply.[2] It was found that all parameters of permissible limit of drinking water, including silicate were not set for all by different agencies, that is, the American Public Health Association, World Health Organization, Indian Standard Institution, Central Pollution Control Board, and Indian Council of Medical Research.[2] Importantly, a significant association was found between the silicate levels in drinking water and the high prevalence of various renal diseases, including stones among residents in certain localities in India.[3] I presume that precise estimate of silicate in the drinking water in the locality of the studied child is indicated and appropriate preventive measure would be needed to hamper the evolution of new cases.Second, the case report sent an important message to the practicing pediatricians to consider infrared spectrophotometry during evaluating urolithiasis in children, including young infants as using silicate-rich water to dilute milk could result in silicateurolithiasis in this particular age group.[4]
