Clinical analysis of urinary tract infections in department of urology

OBJECTIVE To explore the clinical characteristics and risk factors for urinary tract infections in the department of urology so as to provide basis for the clinical prevention and control.METHODS The clinical data of 720 hospitalized patients with urinary tract infections who enrolled the hospital from Feb 2008 to Feb 2011 were analyzed retrospectively.The patients with urinary tract infections and the patients without urinary tract infections were compared in aspects of the general data,indwelling catheterization,prophylactic use of antibiotics,and the length of hospital stay.RESULTS The urinary tract infections occurred in 73 patients of the department of urology with the incidence rate of 10.14%.There were 38 patients with urinary frequency,urgency,and dysuria,12 patients with fever,abdominal pain,and gastrointestinal dysfunction,and 23 patients with the asymptomatic.There were 92 case-times of urine bacterial culture,totally 68 strains of bacteria were isolated,Escherichia coli was the most predominant species,followed by Enterococcus,Staphylococcus aureus,and fungi.The median age of the patients with urinary tract infections was greater than that of the patients without urinary tract infections,with higher proportion in the female patients,longer duration of indwelling catheterization and hospital stay,and more cases of prophylactic antibiotics,the differences were statistically significant as compared with the patients without urinary tract infections.The mortality was 4.11% in the urinary tract infections group,and 0.93% in the non-urinary tract infection group,the difference was statistically significant(χ2=3.78,P0.05).CONCLUSION The incidence rate of urinary tract infections is relatively high in the department of urology.To prevent the infections according to the related infections,reasonably use antibiotics,and shorten the duration of the indwelling catheterization can minimize the incidence of urinary tract infections.
