Introduction: Urolithiasis is the formation of biomineral stones in the urinary tract, kidneys, and bladder. The formation of stones (uroliths) is still a multifactorial and complex phenomenon that has not been clearly understood; this cannot be attributed to a multifactorial leading to increased excretion of stone-forming components. Renal stones' etiology is still not well understood. Some studies stated that demographics in the population have a strong correlation as a risk factor for urolithiasis. This study was aimed to know the correlation between demographic factors in society and urolithiasis composition in the Aceh population between the year 2018 to 2020.Methods: This study included 52 patients diagnosed clinically and radiographically with their first episode of urolithiasis at Dr. Zainoel Abidin General Hospital, Aceh, Indonesia, from 2018 to 2020. All samples were first characterized using Fourier Transform Infrared spectroscopy (FTIR) to obtain the mineralogical compositions.Results: Obtained 52 patients diagnosed with urolithiasis were aged 3-67 years, with most patients (27 patients; 51,92%) were aged 45-64 years old. The mean age of the subjects of this study is 45,52 + 13,90. Of the 52 patients included in this study, 37 patients (71,15%) were male, and 15 patients (28,85%) were female. Of 52 patients, 22 (42,31%) presented with one stone only. Of 52 patients, most of the uroliths consisted of Calcium oxalate monohydrate (Whewellite), which is presented in 27 (51,92%) patients, followed by uric acid (Uricite) in 19 (36,54%) patients.Conclusion: most of the urolithiasis patients were aged 45-64 years. The ratio of male to female patients was found to be 2:1. Most of the patients presented with one stone only. Most of the uroliths consisted of Calcium oxalate monohydrate (Whewellite) as the main composition, followed by uric acid (Uricite).
