Purpose: The aim is to study the diversity in the composition of kidney stones and its association with the basic biochemical metabolic panel in patients with kidney stone disease (KSD). Methods: A cross-sectional prospective study enrolling consecutive patients with KSD attending a tertiary care hospital in Mangalore (India) was undertaken. Mineral compositions of kidney stones were analyzed using attenuated total reflection-Fourier transform infrared spectroscopy. Kidney stones were classified into different groups according to the composition. Metabolic status was assessed to analyze possible association with the kidney stone. Results: A total of 369 patients (male 305 and female 64) in the age group of 43.05 ± 14.3 years were included in the study and showed a high diversity of kidney stone types with >50% with mixed compositions. A significant association was found between pure stone type and gender as well with age group (P < 0.001). Serum calcium levels in the calcium oxalate stone formers were significantly higher (P < 0.001) than others. Similarly, uric acid stone formers showed higher random blood sugar, blood urea, uric acid, and serum creatinine levels (P < 0.001). Urine pH was also found to be a contributing factor for the stone formation (P < 0.001). Stone recurrence did not differ significantly concerning stone composition as well as metabolic status. Conclusion: The study reports a high diversity of the kidney stone types among patients. This finding highlights the increased cases of mixed stones that may be because of various lifestyle factors resulting in altered metabolic status. This finding warrants mechanistic studies to understand the etiology of stone formation. This will enable to develop novel noninvasive interventional strategies and proper preventive strategies to reduce the risk of KSDs.
