“…The sample size was estimated based on the comparison of the proportion of CaOx between males and females. A previous study [ 8 ] of the Norwegian population in 2018 revealed that CaOx was more common in males (75.7%) than females (63.1%). With the expected similar difference of 13%, two-sided type I error of 0.05 and 85% power, the required number of males and females would be 240:240.…”

“…Compared to the past, the prevalence of urolithiasis has increased in most countries over recent decades because of changes in the living standards and dietary habits, as well as improvements in clinical diagnosis procedures [ 3 , 4 , 5 , 6 , 7 ]. Furthermore, the composition of stones has varied across gender, age, and country due to different risk factors [ 6 , 8 , 9 , 10 , 11 , 12 ]. The most frequently found minerals have been calcium oxalate (CaOx), calcium phosphate (CaP), and uric acid (UA), but these also vary among countries [ 6 , 8 , 9 , 10 , 11 , 12 ].…”

Objective To identify the correlation between demographic factors and upper urinary tract stone composition in the Thai population. Method A retrospective observational study of first-time upper urinary tract stone former patients aged over 18 years who underwent stone surgery was performed in a tertiary referral university hospital from January 2013 to May 2018. Collected data included demographic information and stone composition information, which were analysed by the Fourier Transform-Infrared Spectroscopy (FTIR) method. The correlation between the demographic factors and major upper urinary tract stone composition was analysed using Fisher's exact test. Results A total of 480 patients were included in this study. The stones were 319 (66.5%) renal calculi and 161 (33.5%) ureteric calculi. There were 248 (51.7%) single composition stones and 232 (48.3%) mixed composition stones. The major stone compositions were 288 (60.0%) calcium oxalate (CaOx), 125 (26.0%) calcium phosphate (CaP), 40 (8.3%) uric acid (UA), 19 (4.0%) magnesium ammonium phosphate (MAP), five (1.0%) cystine, and three (0.6%) ammonium hydrogen urate (AHU). Gender was correlated with the major stone composition. In females, a correlation was found between the major stone composition and age, diabetes mellitus (DM), and glomerular filtration rate (GFR). The study showed no significant correlation between the major stone composition and dyslipidemia (DLP), hypertension (HT), gout, and body mass index (BMI) in both genders. Conclusion Gender, age, DM, and GFR were the factors affecting the stone composition.

“…Wu et al (23) reported similar results with our study as they reported the results of 12,846 patients and the most common stone type was CO in China (23). Although the overall incidence rate was lower in the general population, a recent 3-year retrospective study from Norway also showed that CO stones were the most commonly seen stones also in this country (17). Similarly, Jindal et al (24) reported the results of 90 patients and the most common stone type was Chi-square test CO in eastern India (24).…”

Aims: To evaluate the stone composition and the distribution of the stone types in the geographical regions of Turkey according to where patients were born and where patients live. Methods: The patients who were treated for urinary system stone disease in our hospital between January 2011 and March 2019 were included in the study. Stone samples were collected by endoscopic stone surgery methods or shock wave lithotripsy. Stone analyses were made with manual chemical analysis methods. Stone types and distribution were recorded according to geographical regions of Turkey. Results: A total of 706 patients who were treated for urolithiasis were included in the study. Calcium oxalate (CO) stones were at the highest rates for both genders [127 (68.6%) and 359 (68.9%), for females and males, respectively]. There were no statistically significant differences in terms of stone types between genders (p=0.323). There were statistically significant more CO (297), uric acid (17), mixed stones (78) in the Anatolian (central) region than the other regions according to the geographical region where patients were born (p<0.001, for each). Additionally, there were significantly more calcium phosphate stone formers (25) in the Anatolian region according to the geographical region where patients lived (p<0.001). Conclusions: CO is the most common stone type in Turkey independently of where patients were born or where patients live. Higher prevalence rates of stone disease and CO stones were seen in Central Anatolia. Both geographic origin and dietary habits affect the incidence of urinary system stone disease.
