One-hundred and thirty cases of hymenosis of female urethral orifice with anomalies from May, 1985 through October, 1990 were studied. The patients all received plastic reconstruction of the urethral orifice, and have been followed up for 3 months to 6 years with a cure and improvement rate of 92.1 percent. This anomaly is one of the important causes causing infection of the lower urinary tract. The mechanism of the pathology and the principles of treatment were discussed.

ObjectiveTo investigate the species and resistance phenotypes of the pathogens causing catheter-associated urinary tract infection (CAUTI) in critically ill patients in West China Hospital of Sichuan University, and to provide the basis for the prevention and treatment of this kind of infection. MethodsThe clinical data and findings of the laboratory examination of the patients, who were admitted to intensive care units and suffered from CAUTI in our hospital during January 2012 to December 2014, were retrospectively analyzed. The pathogens isolates from the urine specimens of the patients with CAUTI and their resistance phenotypes were analyzed. ResultsThree hundred and seventy patients suffering from CAUTI were included in this study. Five hundred and seventeen strains of pathogens were isolated from the urine specimens of these patients, including 222 isolates (42.9%) of fungus, 181 isolates (35.0%) of gram negative bacteria, and 114 isolates (22.0%) of gram positive bacteria. In terms of species distribution, Candida albicans (105 isolates, 20.3%), C.glabrata (78 isolates, 15.1%) and C.glabrata (30 isolates, 5.8%) were the predominant fungus. Among the gram negative bacteria, Escherichia coli (81 isolates, 15.7%), Klebsiella pneumoniae (37 isolates, 7.2%), and Acinetobacter calcoaceticus-baumannii complex (23 isolates, 4.4%) were the main species. Enterococcus faecium (79 isolates, 15.3%) and E.faecalis (13 isolates, 2.5%) were the frequently isolated gram positive bacteria. Analysis of the resistance phenotype showed that the resistance rates to itraconazole, voriconazole and fluconazole of Candida spp. were above 10%. Thirty percent of the isolates of E.coli and K.pneumoniae, and 60% of the isolates of A.calcoaceticus-Baumannii complex were resistant to many of the regular antibiotics. Imipenem resistance rate of A.calcoaceticus-Baumannii complex was 60.8%. Sixty percent of the isolates of E.faecium and E.faecalis were resistant to many of the regular antibiotics. The vancomycin-resistant isolates accounted for 16.5% of E.faecium and 31.0% of E.faecalis. ConclusionCandida species are the major pathogens for CAUTI in critically ill patients in our hospital and show the resistance to azoles. We should focus on the drug resistance of gram negative bacteria and gram positive bacteria. The rational use of antibiotics and application of effective infection control measures are important to decrease the CAUTI.
ObjectiveTo explore the risk factors of community-acquired urinary tract infections caused by extended-spectrum β-lactamase-producing Escherichia coli (ESBLs-producing Escherichia coli). MethodsProspective and retrospective investigation methods were combined, to investigate the hospitalized patients diagnosed with community-acquired urinary tract infections caused by ESBLs-producing Escherichia coli in the Second Affiliated Hospital of Fujian Medical University during July 2012 to December 2014. Statistical analysis was performed using SPSS 19.0 software. The potential risk factors were analyzed by chi-square test or Fisher exact probability method, then, factors with statistical significance identified by single factor analysis were further analyzed by non-conditional logistic regression. ResultsA total of 106 patients were included and divided into a ESBLs group (68 cases) and a control group (38 cases) according to the drug sensitivity test results. The results of single factor analysis indicated: there were significant differences between the ESBLs group and the control group in the use of antibiotics within three months before admission (χ2=11.292, P=0.001), the use of third generation cephalosporin (χ2=11.033, P=0.001), more than three kinds of diseases that could cause urinary tract obstruction (χ2=16.464, P=0.000), anemia (χ2=5.956, P=0.015), indwelling catheter (χ2=6.695, P=0.010), urinary system operations (χ2=9.730, P=0.002). The results of further non-conditional logistic regression analysis showed that more than three kinds of diseases that could cause urinary tract obstruction (OR=14.675, 95%CI 2.699 to 79.796, P=0.002), anemia (OR=7.976, 95%CI 1.785 to 35.632, P=0.007), the use of antibiotics within three months before admission (OR=7.057, 95%CI 1.597 to 31.175, P=0.010), the use of third generation cephalosporin (OR=6.344, 95%CI 1.145 to 35.146, P=0.034) and indwelling catheter (OR=3.844, 95%CI 1.058 to 13.967, P=0.041) were independent risk factors of community-acquired urinary tract infections caused by ESBLs-producing Escherichia coli. ConclusionThe risk factors of community-acquired urinary tract infections caused by ESBLs-producing Escherichia coli include more than three kinds of diseases that could cause urinary tract obstruction, anemia, the use of antibiotics within three months before admission, the use of third generation cephalosporin, and indwelling catheter. The use of antibiotics, especially the third generation cephalosporin, should be strictly controlled, the time of indwelling catheter should be reduced, and the anemia should be corrected, in order to reduce the incidence of community-acquired urinary tract infections caused by ESBLsproducing Escherichia coli.

ObjectiveTo explore the influence of evidence-based nursing care of catheterization on the incidence of urinary tract injury and urinary tract infection in patients with spinal cord injury and long-term indwelling catheters.MethodsFrom July 1st, 2017 to November 30th, 2018, 100 patients with spinal cord injury indwelling catheters in Department of Spinal Surgery were prospectively selected as the research objects. According to the admission time, patients admitted between July 2017 and February 2018 were assigned into the control group (n=50), and patients admitted between March 2018 and November 2018 were assigned into the observation group (n=50). Traditional catheter placement was used in the control group, while evidence-based catheter placement was used in the observation group. The incidences of catheter-related urethral injury and urinary tract infection after the catheterization were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, diagnosis, or length of hospital stay between the two groups (P>0.05). Catheter placement was performed 57 times in the control group and 59 times in the observation group during hospitalization. After catheterization, the incidences of urethral hemorrhage and gross hematuria in the control group [22.80% (13/57) and 15.78% (9/57), respectively] were higher than those in the observation group [both were 1.69% (1/59)], with statistical differences between the two groups (P<0.05). The incidence of urinary tract infection in the control group differed from that in the observation group [42.0% (21/50) vs. 18.0% (9/50), P=0.009].ConclusionThe evidence-based urinary catheterization method for patients with spinal cord injury and long-term indwelling catheter can effectively prevent catheter-related urinary tract injury, reduce the incidence of catheter-related urinary tract infection during hospitalization, and improve the quality of clinical care.

ObjectiveTo analyze the related risk factors for catheter-associated urinary tract infection in the Intensive Care Unit (ICU), and make corresponding nursing countermeasures. MethodsBy target monitoring of catheter-associated urinary tract infection in 184 patients in the ICU from 2011 to 2012, infection risk factors were analyzed. The measures of nursing interventions had been taken since January 2012, and the effects before and after the intervention were contrasted and evaluated. ResultsBefore the intervention, 951 out of 1 229 patients in 2011 had indwelling catheter, and catheter-associated urinary tract infection occurred in 127 patients with an infection rate of 13.35%. After the intervention, 841 out of 1 437 in 2012 had indwelling catheter, and catheter-associated urinary tract infection occurred in 57 patients with an infection rate of 6.78%. ConclusionTaking effective intervention measures can effectively reduce the ICU catheter-associated urinary tract infection and it also ensures the safety of medical care.
