ObjectiveTo establish the risk assessment scoring system for urinary tract infection(UTI)  in patients in urology department,  and provide reference for the prevention of UTI. Methods470 patients admitted to the urology department of a hospital from May 2011 to May 2014 were enrolled in the study, logistic regression model was constructed to analyze influencing factors, risk assessment scoring system was established, effect of model prediction was assessed with ROC curve. Results31 cases of UTI occurred among 470 patients (6.60%). Logistic regression analysis showed that age, combined underlying diseases, length of hospital stay, duration of indwelling catheter, and combination use of antimicrobial agents were independent risk factors for UTI. The risk assessment scoring system was as follows: aged≥60 scored 2 points,  with complications 1 point, length of hospital stay≥10 days 3 points, duration of indwelling catheter≥5 days 6 points, used ≥2 kinds of antimicrobial agents 2 points. Patients with the risk assessment score ≥11 points were the population at high risk of UTI. The area under ROC curve(AUC) of the scoring system in model group was 0.89， sensitivity and specificity were 84.9% and 81.6% respectively; AUC in validation group was 0.69， sensitivity and specificity were 77.2% and 62.4% respectively.  ConclusionRisk assessment scoring system of UTI in patients of urology department has been established and validated，it is helpful for monitoring high risk patients, and reducing the occurrence of infection.
