Abstract :
Objective: To evaluate the spectrum of urinary tract stone compositions in patients managed at one center. Methods: A total of 710 urinary calculi, passed spontaneously or after extracorporeal shock-wave lithotripsy as well as collected by endoscopic or open surgical procedures were analyzed by applying chemical and physicochemical methods primarily used for detecting minerals in our laboratory. Results: The distribution of stone compositions were noted as 454 (64.9%) calcium oxalate; 104 (14.6%) calcium phosphate; 99 (13.9%) struvite; 24 (3.3%) uric acid; 21 (2.9%) mixed; 5 (0.7%) cystine; and 3 (0.4%) xantine stones. Conclusion: Calcium stones, calcium oxalate in particular predominate among other types of urinary calculi in our center. Infection stones still have a considerable incidence that stays near to calcium phosphate calculi. This data can be helpful for dietary recommendations and treatment plans in cases without stone type assessment.
