  • Purpose : Suprapubic aspiration(SPA) has been considered the "gold standard" for obtaining urine in non-toilet trained infants. Ultrasound(US)-guided SPA improves the success rate of the procedure and reduces the complications. However, many physicians perceive SPA as invasive and prefer the use of urethral catheterization (Ucat). We compared the success rate, complications and accuracy of US-guided SPA and Ucat. Methods : 121 infants who visited Ewha Womans University Mokdong Hospital with suspected urinary tract infection(UTI) were investigated. For the first study, the study infants were randomly assigned to either the US-guided SPA(n=32) or Ucat(n=32) groups. The success rate and complications of both procedures were compared. For the second study, US-guided SPA and Ucat were performed simultaneously(n=57). The accuracy of urethral catheterization was subsequently analyzed. The criteria for success was defined as the collection of more than 0.5 mL of urine. UTI was diagnosed by the presence of uropathogens over 105 colony-forming units (CFU)/mL. Results : The overall success rate of the US-guided SPA was 96.9%(71.9% in first attempts, 25.0% in second attempts) which was not significantly different compared to 96.9%(90.6% in first attempts, 6.3% in second attempts) in the Ucat(P>0.05) group. The aspirated urine volume was $7.4{\pm}3.7mL$ in the US-guided SPA group, which was not significantly different to $4.5{\pm}2.6mL$ in the Ucat(P>0.05) group. The accuracy of Ucat in comparison to the US guided SPA was low with sensitivity 59.5%, specificity 86.6%, false-positive rate 13.3% and false-negative rate 40.5%. Conclusion : US-guided SPA should be encouraged as the best method to collect the urine in non-toilet trained infants with UTI.

  • The purpose of this study was to analyze reflected status of evidence-based guideline on nursing textbook for prevention of catheter-associated urinary tract infections (CAUTIs). The subjects were 14 fundamental nursing textbooks consisting of 7 theoretical and 7 practical books published from March 2012 to March 2017. The evidence-based guideline was consisted of ninety-one recommendations for prevention of CAUTIs which were comprehensively collected from five guidelines. Collected data were analyzed using descriptive statistics. Reflected rate on theoretical and practical fundamental nursing textbooks were 23.0% and 15.2% respectively. The most reflected domains in theoretical and practical textbooks was catheter management and catheter insertion respectively. Sixteen out of 91 individual recommendations with more than 50% consistency rate were identified, and eight (50.0%) recommendations on the catheter maintenance area were identified. Lastly nine inconsistent recommendations were identified. And the most frequent discrepancies were indwelling catheterization for management of urinary incontinence, followed by regular changing indwelling catheter, clamping prior to removal and perineal care. In conclusion, we found that recommendations for the CAUTIs guidelines were poorly reflected on text books. Further revising fundamental nursing textbook should correct the discrepancies between textbooks and the guidelines.

  • Purpose: This study was carried out to investigate the effect of a decrease in indwelling catheter size and preoperative education on bladder discomfort and nursing needs. The study was conducted on patients in the recovery room after their surgery. Methods: This study is a randomized control trial. Data were collected from September 2011 to February 2012 at a university hospital in Bundang, Korea. The sample consisted of 75 patients, excluding one patient from the experimental group 2. From among the patients that were sent to the ICU, 24 were in experimental group 1, 24 were in experimental group 2, and 27 were in the control group. Data were collected and analyzed using a chi-square test, t-test, and one-way ANOVA. Results: There were significant differences between the bladder discomfort experienced by patients in experimental group 1 and the control group, and experimental group 2 and the control group. Then nursing needs of the control group were higher than those of the experimental groups 1 and 2. Conclusion: The decrease in indwelling catheter size and preoperative nursing education is an effective nursing intervention in perioperative care.

  • Integrating micro-machined sensors and actuators on the conventional devices with the copper power lines was incompatible to fabricate the mass produced micro electromechanical system (MEMS) devices. To achieve the compatibility of the wiring method between MEMS parts and devices, we developed the three-dimensional sputter-evaporation system that coats micropatterned thin copper films on the surface of the MEMS element. The system consists of a process chamber, two branch chambers, the substrate holder, and a linear-rotary motion feedthrough. Thin copper film was sputtered and evaporated on the biocompatible polymer, Pellethane$^{circed{R}}$ and silicone, catheter that is 2 mm in diameter and 700 mm in length. The metal film coating technique with three-dimensional thin film sputter-evaporation system was developed to apply the power and signal lines on the micro active endoscope. In this paper, we developed the three-dimensional metal film sputter-evaporation system operated on the low temperature for the biopolymeric substrates used in the medical MEMS devices.

  • Urinomas can occur after renal trauma or perforation of the collecting system during an endosurgical procedure. However, spontaneous urinomas are very rare. Here we report a case of a spontaneous perinephric urinoma following the removal of a Foley catheter in an 18-year-old girl with acute kidney injury caused by septic shock. The patient had been treated for septic shock, acute kidney injury, and acute respiratory distress syndrome, and had a Foley catheter in place for seven days. After Foley catheter removal, the patient complained of consistent voiding difficulty. An abdominal computed tomography scan showed a large amount of left perinephric fluid, and the aspirated fluid included urothelial cells, confirming the diagnosis of a urinoma. The urinoma was successfully treated by insertion of a double-J stent into the left ureter. This report discusses the available literature on urinomas, and their clinical features, diagnosis, and treatment.

  • Purpose: In this study, we aimed to explore the risk factors for catheter-associated urinary tract infections (CAUTI) in patients receiving home care nursing. Methods: A total of 117 participants registered for home care nursing provided by the University of C hospital in Seoul were included in the study. Data were based on a survey and urine examination results from June to July 2018. Results: Asymptomatic bacteriuria was identified in 96 (82%) patients. Age, sex, activity, diabetes mellitus, mental status, presence of other diseases, catheter material type, catheter size and fixation, hand washing (care giver), gloving (care giver), perineal care, and bladder irrigation were not recognized as risk factors for CAUTI. Age and catheterization duration were associated with CAUTI. Conclusions: Old age was found to be a risk factor for CAUTI (p=0.048). CAUTI incidence decreased as catheter use exceeded 70 months (p=0.028).

  • The objective of this investigation is to examine the influence of the micro catheters, which mimic the intravascular micro active endoscopes, on local pressure changes and flow rate in an arterial branch model similar to the femoral artery of human. The effects of branch to main lumen flow rate ratios and the locations of a catheter tip were found to be significant on the local pressure changes. Relatively large pressure drops and an increase in shear stress due to the obstruction effects may induce an endothelial cell damage and a change in arterial wall permeability, which have been reported to be the primary cause of the initiation of the atherosclerosis and other major vascular diseases.

  • Purpose: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. Methods: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. Results: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. Conclusion: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

  • Purpose: To implement evidence-based nursing, it is important to know where and how to find the best available evidence. This study was conducted to identify the results of a search from Ovid MEDLINE and to compare the results from Ovid MEDLINE with those from PubMed MEDLINE. Methods: Four different approaches via Ovid MEDLINE were used to search for guidelines on preventing catheter-associated urinary tract infections. Outcomes of this study were the number of records and relevant literature, and the sensitivity and precision of the search methods via Ovid MEDLINE. Results: The number of retrieved items ranged 23 to 6,005 and that of relevant studies, 5 to 8 of 8. Simple searches resulted in the highest sensitivity of 100.0%. When using MeSH terms and limits feature, the precision was highest (21.7%) among four approaches for literature searches. Simple searches in Ovid had higher sensitivity and lower precision than those in PubMed. Conclusion: Simple searches in Ovid may be inefficient for busy clinicians compared to PubMed. However, to ensure a comprehensive and systematic literature search, using Ovid MEDLINE in addition to PubMed is recommended.
