Introduction: The prevalence of urinary stones in different parts of the world is estimated to be in the range of 1-15% and Iran has identified as one of the "stone belt" countries with a prevalence of 2-3%. This study aimed to determine the epidemiology of urinary stones in patients referred to Ganjavian hospital at Dezful-Iran from 2010 to 2015. Materials and Methods: The study population included 519 adult patients over 15 years old with a diagnosis of urinary stone who were retrospectively assigned to the study. Data collection tools included a demographic checklist and patient biochemical tests. Results: The frequency of male and female patients was 69.6 and 30.4%, respectively. The mean age was 47.1 years. The patients’ medical history included urinary stone (43%), diabetes (18%), hypertension (29.7%), cardiac chronic disease (0.6%), hyperlipidemia (0.8%), chronic kidney disease (1%), prostatic hypertrophy (0.6%), urethral stricture (0.6%), urinary tract infection (0.6%), cyst (1.2%) and others were without underlying disease. Conclusion: Various epidemiological factors such as age, sex, hypertension, high blood sugar and history of medications are effective in getting urinary stone. So, by identifying the susceptible patients and teaching them, the burden of the disease on society and the individual can be reduced.
