Objective: This study aimed to establish the epidemiology of urinary stone disease in a tertiary government hospital setting. Methodology: The data of patients diagnosed with urolithiasis from July 1, 2003 to December 31, 2005 were retrieved from an electronic surgical database. Parameters such as age, sex, diagnosis, type of consult, anatomic location of the stone, composition and mode of management were determined. Results: A total of 985 patients and 1,109 stones were profiled. Urolithiasis was most common among males in their late adulthood. Urinary stones were most commonly found in the urinary bladder. Majority of the stones were of the mixed type, containing calcium oxalate. Prostatic enlargement was the most common anatomic abnormality associated with urolithiasis. Most of the patients consulted on an elective basis. Open stone surgery still ranked as the most common mode of management. Conclusion: This study shows that urolithiasis is a common condition in inhospital Filipino urologic practice. The clinical presentation of urinary stone disease in Filipinos is similar in some aspects to the reports from other Asian countries and in other aspects to data from Western literature.
