Effect of Preoperative Double-J Ureteral Stenting before Flexible Ureterorenoscopy on Stone-free Rates and Complications.

The effect of preoperative Double-J (DJ) ureteral stenting before flexible ureterorenoscopy (FURS) in the treatment for urinary stones was evaluated. We retrospectively enrolled 306 consecutive patients who underwent FURS from Jan. 2014 to Dec. 2017. All the patients were classified into two groups according to whether they had DJ ureteral stenting before FURS. Baseline characteristics (age, sex, stone location, stone size, surgical success rate, operation time, stone-free rate of the first day after surgery, stone-free rate of the first month after surgery, total complication rate) were compared using Chi-square test for categorical variables and Kruskal-Wallis test for continuous variables. In total, 306 patients were included in this study. The group of DJ stenting before FURS included 203 (66.3%) patients, and non-DJ stenting before FURS was observed in 103 (33.7%) patients. The group of DJ stenting before FURS was significantly associated with a shorter operation time (53.8 vs. 59.3 min, P<0.001), a higher stone-free rate of the first day after surgery (69.0% vs. 51.5%, P=0.003). However, statistical significant differences were not found in the age, sex, stone location, stone size, surgical success rate, stone-free rate of the first month after surgery (89.2% vs. 81.6%, P=0.065) and total complication rate (5.4% vs. 9.7%, P=0.161) between the two groups. Preoperative DJ ureteral stenting before FURS could reduce the operation time and increase stone-free rate of the first day after surgery. However, it might not benefit the stone-free rate of the first month after surgery and reduce the complication rate. Preoperative DJ stenting should be not routinely performed.

Impact of an evidence-based intervention on urinary catheter utilization, associated process indicators, and infectious and non-infectious outcomes.

BACKGROUND: Multi-centre intervention studies tackling urinary catheterization and its infectious and non-infectious complications are lacking. AIM: To decrease urinary catheterization and, consequently, catheter-associated urinary tract infections (CAUTIs) and non-infectious complications. METHODS: Before/after non-randomized multi-centre intervention study in seven hospitals in Switzerland. Intervention bundle consisting of: (1) a concise list of indications for urinary catheterization; (2) daily evaluation of the need for ongoing catheterization; and (3) education on proper insertion and maintenance of urinary catheters. The primary outcome was urinary catheter utilization. Secondary outcomes were CAUTIs, non-infectious complications and process indicators (proportion of indicated catheters and frequency of catheter evaluation). FINDINGS: In total, 25,880 patients were included in this study [13,171 at baseline (August-October 2016) and 12,709 post intervention (August-October 2017)]. Catheter utilization decreased from 23.7% to 21.0% (P=0.001), and catheter-days per 100 patient-days decreased from 17.4 to 13.5 (P=0.167). CAUTIs remained stable at a low level with 0.02 infections per 100 patient-days (baseline) and 0.02 infections (post intervention) (P=0.98). Measuring infections per 1000 catheter-days, the rate was 1.02 (baseline) and 1.33 (post intervention) (P=0.60). Non-infectious complications decreased significantly, from 0.79 to 0.56 events per 100 patient-days (P<0.001), and from 39.4 to 35.4 events per 1000 catheter-days (P=0.23). Indicated catheters increased from 74.5% to 90.0% (P<0.001). Re-evaluations increased from 168 to 624 per 1000 catheter-days (P<0.001). CONCLUSION: A straightforward bundle of three evidence-based measures reduced catheter utilization and non-infectious complications, whereas the proportion of indicated urinary catheters and daily evaluations increased. The CAUTI rate remained unchanged, albeit at a very low level.

Effectiveness of silver alloy-coated silicone urinary catheters in patients with acute traumatic cervical spinal cord injury: Results of a quality improvement initiative.

Patients with acute traumatic cervical spinal cord injury (ATCSCI) have an increased risk of catheter-associated urinary tract infection (CAUTI). The effectiveness of silver alloy-coated silicone urinary catheters (SACC) in preventing CAUTI in ATCSCI is unknown and was the objective of this study. We performed a quality improvement initiative in an attempt to reduce CAUTI in patients undergoing spine surgery at a single quaternary center. Prior to July 2015, all patients received a latex indwelling catheter (LIC). All patients with ATCSCI with limited hand function (AIS A,B, or C) received a SACC. Incidence of CAUTI, microbiology, duration of infection, antibiotic susceptibility, and catheter-associated adverse events were recorded prospectively. We studied 3081 consecutive patients over the three years, of whom 302 (9.8%) had ATCSCI; 63% of ATCSCI patients were ASIA Impairment Scale (AIS) A or B. The overall rate of CAUTI was 19% (585/3081), and was 38% (116/302) in patients with ATCSCI. Of 178 ATCSCI patients with LIC, 100 (56%) developed a CAUTI compared with 28 of 124 (23%) patients with SACC (p < 0.05). Poly-microbial and gram-positive infection was more common in LIC than in SACC (p < 0.05). Median duration of infection was 9 days in SACC group and 12 days in LIC group (p = 0.08). Resistance to trimethoprim (p < 0.001) and ciprofloxacin (p < 0.05) were more common in LIC group. There was no difference in catheter-associated adverse events or length of stay between the groups. This quality improvement initiative illustrates the effectiveness of antiseptic silver alloy-coated silicone urinary catheters in patients with ATCSCI. In our population, the use of SACC reduces the incidence and the complexity of CAUTI.

A Randomized Controlled Trial of Enhanced Recovery After Surgery Versus Standard of Care Recovery for Emergency Cesarean Deliveries at Mbarara Hospital, Uganda.

BACKGROUND: Enhanced recovery after surgery (ERAS) expedites return to patient baseline and functional status by reducing surgical trauma, stress, and organ dysfunction. Despite the potential benefits of enhanced recovery protocols, limited research has been done in low-resource settings, where 95% of cesarean deliveries are emergent and could possibly benefit from the application of ERAS protocols. METHODS: In a prospective, randomized, single-blind, controlled trial, mothers delivering by emergency cesarean delivery were randomly assigned to either an ERAS or a standard of care (SOC) recovery arm. Patients in the ERAS arm were treated with a modified ERAS protocol that included modified counseling and education, prophylactic antibiotics, antiemetics, normothermia, restrictive fluid administration, and multimodal analgesia. They also received early initiation of mobilization, feeding, and urethral catheter removal. The primary end point was length of hospital stay. The secondary end points were complications and readmission rates. Mean length of stay in the intervention and control arms were compared using t tests. Statistical analyses were performed using STATA version 13 (College Station, TX). RESULTS: A total of 160 patients were enrolled in the study, with 80 randomized to each arm. There was a statistically significant shorter length of stay for the ERAS arm compared to SOC, with a difference of -18.5 hours (P < .001, 95% confidence interval [CI], -23.67, -13.34). The incidence of complications of severe pain and headache was lower in the ERAS arm compared to SOC (P = .001 for both complications). However, pruritus was more common in the ERAS arm compared to SOC (P = .023). CONCLUSIONS: Use of an ERAS protocol for women undergoing emergency cesarean delivery in a low-income setting is feasible and reduces length of hospital stay without generally increasing the complication rate.

Ins and outs of urinary catheters

BACKGROUND: Inserting an indwelling catheter (IDC) is a common medical procedure that is often performed poorly and inappropriately, and can lead to significant morbidity. Although most catheterisations are performed by nursing staff, medical personnel need to be aware of the procedure, products and common IDC complications. OBJECTIVE: Current guidelines and literature were reviewed to outline catheterisation indications, catheter types and provide a general understanding of complications associated with IDCs for the general practitioner (GP). DISCUSSION: There is evidence that IDCs are often used when not indicated and improperly managed when inserted. IDCs can cause significant morbidity, prolong hospital stay and increase healthcare costs. Infection and traumatic insertion are common complications; advances in catheter design have helped to limit these complications. Most complications are avoidable, do not require specialist input and can be managed by community nurses or GPs. Reviewing indications, adopting proper technique for insertion and defining management strategies can limit complications.

Applying preventive measures leading to significant reduction of catheter-associated urinary tract infections in adult intensive care unit.

OBJECTIVES: To determine the impact of applying the best available clinical evidence on the preventive measures to reduce the rate of catheter-associated urinary tract infections (CAUTI) in adult intensive care units (ICU).     Methods:  Data were collected from adult ICUs (28 beds) from 2008 to 2016. The proper use of silicon catheter, aseptic insertion technique, emptying bag three-fourth via close circuit, the use of appropriate size catheter, securing the draining tube on the thigh to keep catheter bag below patient's bladder level and removal of the catheter as early as possible were ensured in all patients.   Results: Rate of UTI and urinary catheter utilization ratios were reviewed during the study period. There was a mean of 6,175 catheter days/year for ICU. Despite the overall rise in the urinary catheterization ratio over these years; we observed a significant reduction in the UTI rate per 1000 Urinary catheter days; from 2.3 in 2010 to 0.3 in 2011 and it was sustained through 2016.  Conclusion: The monthly rates of CAUTI significantly declined after the enforcement of agreed strategies and interventions to prevent CAUTI rates in adult ICU.

[Medical quality standards for selected urological aids and devices : Consensus for patients with neurogenic urinary bladder dysfunction]. / Medizinische Qualitätsstandards ausgewählter urologischer Hilfsmittel : Konsens für Patienten mit neurogenen Harnblasenfunktionsstörungen.

BACKGROUND: Using the CE mark of therapeutic appliances is, on its own, not sufficient enough for their appropriate and effective application. In order to treat the patient successfully, not jeopardizing the success of the treatment, medical quality criteria for therapeutic appliances care are necessary to acceptably compensate for a patient's disabilities. OBJECTIVES: Medical quality criteria are formulated for the most frequently used urological aids and devices, considering hygienic requirements, international literature and the practical experience of physicians and nurses with regard to the care of patients with neurogenic urinary bladder dysfunction. METHODS: An expert group of urologists, surgeons, rehabilitation physicians and nurses has developed medical quality criteria via a structured consensus procedure. Developing these criteria, the group has taken into account current jurisprudence, the current resource directory of neurourological relevant aids, data from international literature and hygiene requirements. RESULTS: Medical quality requirements are discussed and defined for selected groups of urological devices (single use catheters, indwelling catheters, external catheters, urine bags, templates and diapers as well as devices for the electrostimulation of nerves). CONCLUSION: The presented quality requirements offer the possibility to stabilize quality of care with neurourological relevant therapeutic appliances. The catalogue of therapeutic appliances must be urgently updated. Urinal catheters for single use must be classified as an individual product group. Devices for anterior root stimulation and neuromodulation must be included in the resource directory. The incontinence severity classification needs to be reviewed.

[Urinary catheter : comply with guidelines to avoid infections]. / Sonde urinaire : respecter les indications pour éviter les infections.

Catheter-associated urinary tract infection (CAUTI) is the most frequent hospital acquired infection, associated with significant morbidity, mortality and health care costs. Up to 50 % of urinary catheter use in hospital are for incontinence or convenience without proper indication. In addition, urinary catheters are not removed when no longer necessary, due to a lack of vigilance of the health care team. The duration of catheterization is the most important risk factor for the development of CAUTI. Simple measures to prevent CAUTI include appropriate use, maintaining awareness of catheters in place and use of different alternatives. These measures can reduce the number of CAUTI over 50 % along with positive impact on the quality of care and costs.

Les infections liées aux sondes urinaires sont les infections nosocomiales les plus fréquentes avec un impact majeur sur la morbi-mortalité et les coûts de la santé. Près de la moitié des patients sondés le sont sans indication formelle. De plus, les sondes urinaires sont laissées en place plus longtemps que nécessaire, souvent en raison d'un manque de vigilance des soignants. Or, le risque de développer une infection est étroitement lié à la durée du sondage. Des mesures simples pour améliorer la sécurité des patients consistent à respecter les indications, penser aux différentes alternatives et réévaluer quotidiennement la nécessité des sondes. Ces mesures permettent de diminuer le nombre d'infections urinaires liées aux sondes de plus de 50 % avec un impact positif sur la qualité de la prise en charge et une diminution des coûts.

Quantification of User and Manufacturer Variabilities in Urinary Catheter Anchoring Balloon Inflation and Mitigation of Variability by Flow Resistance.

OBJECTIVE: To quantify user variability and manufacturer variability in urinary catheter anchoring balloon inflation pressure and to mitigate any significant variance by incorporating flow resistance into the anchoring balloon inflation process. METHODS: Inflation of a urinary catheter anchoring balloon was performed at atmospheric pressure by different users (n = 8) to investigate user variability. A calibrated pressure transducer measured inflation pressures, and a video extensometer measured balloon inflation profiles. Manufacturer variability was investigated by applying constant forces to the plunger of conventional syringes to mimic "heavy-," "intermediate-," and "light"-handed users for 3 brands of catheter. Flow restrictors of variable reduced cross-sectional areas were introduced to the outflow of the inflation syringes to investigate the effect of flow resistance on anchoring balloon inflation profiles. RESULTS: Variations in maximum inflation pressures (range: 75-355 kPa) were observed among the different users. There were no significant differences in maximum inflation pressure between brands at any of the 3 simulated hand forces (P = .97). Increasing the flow resistance significantly reduces the applicable inflation pressure of all hand forces (P < .001). Specifically, the difference in inflation pressure between heavy- and light-handed forces is reduced from over 405 kPa to under 65 kPa. Introducing flow resistance does not result in a significant difference in inflation pressure between brands (P = .254). CONCLUSION: There is significant user variability in urinary catheter balloon inflation pressure. This variation can be significantly reduced by introducing flow resistance to the inflation technique.

Does Size Matter? Measured and Modeled Effects of Suprapubic Catheter Size on Urinary Flow.

OBJECTIVE: To quantify the effects of catheter size and urinary sediment on catheter drainage, and to determine the French size at which catheter upsizing yields a diminished marginal return in flow. MATERIALS AND METHODS: Latex Foley catheters (12-26 French [Fr]) were connected to a simulated bladder. Passive drainage times of 450 mL water were measured over 5 successive trials for each catheter size. The effect of sediment was modeled by adding 2g of infant rice cereal to the water. Measurements were repeated in half-length catheters to assess the effect of catheter length. A computational model of resistance was compared to measured data. Percent differences in catheter resistance based on measured catheter dimensions were determined. RESULTS: Catheter resistance significantly decreased (P < .001) with increasing catheter size. All catheter sizes had significantly faster (P < .001) drainage times after being shortened, except for the 16 Fr catheter. All catheter sizes exhibited significantly prolonged (P < .001) drainage times after the addition of sediment, except for the 16 Fr catheter. Beyond 18 Fr, larger catheter sizes provided diminishing marginal returns in flow; upsizing from 18 Fr to 20 Fr reduced measured resistance by 19%, which was the lowest improvement in resistance between 2 catheter sizes. The coefficient of determination (R2) between measured and modeled resistances was 0.9754, confirming that the model of catheter performance was accurate. CONCLUSION: Marginal improvement in urine flow occurs with catheter upsizing after 18 Fr; however, shortening catheter lengths may serve as another means of improving flow.

Innovation in catheter securement devices: minimising risk of infection, trauma and pain.

Urinary catheters are one of the most common invasive devices used in the NHS. The risks are well-documented and the practice of catheterisation of the bladder has been around for years. Traditionally catheter fixation devices have not been widely used, despite many best practice guidelines advising on their use as a standard within catheter care and maintenance. This article considers some of the evidence around urinary catheterisation and the benefits and limitations of fixation devices. There will be a product focus on the Optimum Medical Ugo Fix Gentle catheter fixation device, with case histories to demonstrate patient satisfaction with the product.

Standards of care for feline urethral catheters in the UK.

OBJECTIVES: This study aimed to determine the standards of care for urethral catheters (UCs) placed in male cats for treatment of urethral obstruction (UO). It also assessed whether these standards were influenced by year of graduation of the veterinary surgeon (VS). METHODS: One hundred veterinary practices were randomly selected, and a telephone survey was conducted with a VS in the practice. Regarding the last urethral catheterisation performed for a male cat with UO, the VS was asked about the use of antibiotics while the catheter was in situ, whether a closed urinary collection system was used, whether aseptic skin preparation of the patient was performed and whether aseptic hand preparation was performed. A χ(2) test was used to determine whether there were significant differences in these percentages when considering year of graduation. RESULTS: Twenty-seven percent of VSs did not use antibiotics while the urethral catheter was in place, 44% used closed urinary collection systems, 41% performed aseptic skin preparation of the patient and 60% aseptically prepared their hands and wore sterile gloves. There was a statistically significant (P <0.01) difference in antibiotic usage, closed collection system usage and aseptic hand preparation across graduation year groups. CONCLUSIONS AND RELEVANCE: Non-sterile urethral catheter placement with open urinary drainage and antibiotic prophylaxis is still a widespread practice among VSs; however, more recent graduates are more likely to perform the procedure aseptically with a closed urinary collection system and withholding of antibiotics. There is a need for further education for postgraduate veterinarians in the prevention of catheter-associated urinary tract infections in cats and further research to provide evidence-based guidelines for feline urethral catheter care.
