Abstract:

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.
