ABSTRACT

Objective A retrospective study was conducted to investigate the clinical epidemiology of ufinary calculus in Hubei province to provide the population characteristics,stone distribution characteristics,treatment methods,surgical costs and other clinical epidemiological data of patients with trinary calculus,and to provide clinical evidence for the development of prevention and treatment measures for urinary calculi.Methods According to the geographical position,local tertiary hospitals were selected as survey objects and medical records such as age,sex,occupation,stone position,type of operation,and cost of surgical treatment of urinary stone disease were retrospectively investigated between January,2015 and December,2017.Result A total of 193 784 patients were enrolled in this study from 27 hospitals in Hubei province.In which,76 209 were admitted to the hospital for urinary calculus,accounting for 39.33％.Among them,49 460 patients were males (64.90％) and 26 749 were females(35.10％),which the ratio was 1.85∶ 1.All age groups can suffer from urinary calculus,with the peak age range from 41 to 70 years old with 58 985 cases,accounting for 77.40％.The main proportion of patients with urinary calculus were farmers with 21 818 cases (28.63％),comparing with workers (9.74％),busioess man (5.58％),government employees (5.14％),retirees (11.25％) and unemployed (12.58％).A total of 71 439 patients with upper urinary calculus and 4 770 patients with lower urinary calculus and the ratio of upper and lower urinary calculus was 14.98∶ 1.From 2015 to 2017,23 567 patients with urinary calculi underwent ureteroscopic]ithotripsy,and 14 681 patients underwent percutaneous nephrolithotomy.The average operation cost of patients with urolithiasis was 18 395.52 RMB,18 566.31 RMB,19 080.91 RMB in 2015,2016,2017 respectively.Conclusion Hubei province is an area with high incidence of urinary calculus,accounting for 39.33％.The high incidence age is 41-70 years.The occupation composition is mainly farmers.In the past three years,the cost of surgery gradually increased.
