Knowledge and experience of medical students with male urethral catheterization

Background: Urethral catheterization is a commonly performed procedure. Therefore medical students should receive adequate training in this technique to avoid devastating consequences of performing it poorly. This study was aimed at finding out the knowledge and experience of final year medical students with the technique of male urethral catheterization.Methods: Well-structured questionnaire was administered to each of the final year medical students of Ladoke Akintola University of Technology (LAUTECH) one week to their final examinations.Results: All the 215 students received the questionnaire one week before their final examinations with 128 (60%) completing it. The male to female ratio was 1:1 with a mean age of 28 years. One hundred and twenty-five (98.4%) of the students had been throught male urethral catheterization. Thirty-five (27.6%) of the students have never performed male urethral catheterization. One hundred and fifteen students (90.6%) agreed that urethral catheterization is a sterile procedure. Sixty-nine (54.3%) students said xylocaine jelly should be used as lubricant.. Ninety four (74%) students said that they will inflate the balloon of the catheter when the Y junction gets to the tip of the penis. Forty-nine (38.6%) students said they are very confident about male urethral catheterization, 61 (48.0%) said reasonably confident while 5 (3.9%) are not confident at all.Conclusions: Urethral catheterization is a common procedure. Students should receive adequate instruction in this technique to avoid devastating consequences of performing it poorly

Clean intermittent self-catheterization as a treatment modality for urinary retention : perceptions of urologists

Purpose: Clean intermittent self-catheterization (CISC) is now considered the gold standard for the management of urinary retention. In the literature, several articles on patients' perspectives on CISC and adherence to this technique have been published. No studies have yet explored the points of view of professional caregivers, such as nurses and doctors. The aim of this study was to explore the opinions of urologists about CISC and to evaluate the need for dedicated nurses specialized in CISC through a self-administered questionnaire. Methods: A questionnaire was developed to explore the opinions of professional caregivers about self-catheterization and to evaluate the need to provide nurses with specialized education in CISC. Questionnaires were sent to 244 urologists through email. We received 101 completed questionnaires. The response rate was 41.4%. Results: Hand function, the presence or absence of tremor, and visual acuity were rated as the most important determinants for proposing CISC to a patient. Twenty-five percent of the urologists reported that financial remuneration would give them a greater incentive to propose CISC. The lack of dedicated nurses was reported by half of the urologists as a factor preventing them from proposing CISC. A meaningful number of urologists thought that patients perceive CISC as invasive and unpleasant. Although most urologists would choose CISC as a treatment option for themselves, almost 1 urologist out of 5 would prefer a permanent catheter. Conclusions: This questionnaire gave valuable insights into urologists' perceptions of CISC, and could serve as the basis for a subsequent broader international study. Further research should also focus on the opinions of nurses and other caregivers involved in incontinence management. Apart from financial remuneration, it is also clear that ensuring sufficient expertise and time for high-quality CISC care is important. This could be a potential role for dedicated nurses

Influence of Obesity, Race and Gender on Cardiac Catheterization after Stress Testing

Female gender and black race have been associated with lower use of cardiac resources however; these patients also have a higher prevalence of obesity. Therefore we determined their relation to cardiac catheterization after stress testing. Clinical characteristics were determined for all patients stress tested over one year at a safety-net, urban, teaching hospital. Subsequent cardiac catheterizations were identified. Univariate and multivariate analyses were performed to determine the factors associated with catheterization. 3644 patients underwent stress testing and 484 (13%) underwent cardiac catheterization. The population was 58% female, 33% black, 53% were obese and 32% lacked insurance. Obese patients were mostly female, disproportionately black and had more CAD risk factors. An ischemic stress test result was similar across all BMI categories. Obesity was not associated with receipt of catheterization. Although univariate analysis showed fewer catheterizations for female and black patients, multivariate analysis adjusting for stress data and clinical risk factors no longer showed this. Neither race, gender, nor obesity was associated with catheterization utilization when stress testing and clinical factors were considered in a center where financial obstacles to testing were minimized

Local DRLs and automated risk estimation in paediatric interventional cardiology

Introduction : Cardiac catheterization procedures result in high radiation doses and often multiple procedures are necessary for congenital heart disease patients. However, diagnostic reference levels (DRL) remain scarce. Our first goal was finding the optimal DRL parameter and determining appropriate DRLs. The second goal was to calculate organ doses (OD), effective doses (ED) and lifetime attributable risks (LAR) per procedure and to provide conversion factors based on dose area product (DAP). Materials and methods : DRLs are calculated for each procedure type, as the 75th percentile of the cumulative value per procedure from the corresponding parameter. All irradiation events in the DICOM Structured Reports were automatically processed and simulated using PCXMC, resulting in OD, ED and LAR. Using a Kruskal Wallis H test and subsequent pairwise comparisons, differences in median values of the DRL parameter between procedure types were assessed. Results : Linear regression showed a strong correlation and narrow confidence interval between DAP and product of body weight and fluoroscopy time (BWxFT), even when all procedures (diagnostic and interventional) are combined. Only 15% of the pairwise comparisons were statistically significant for DAP normalized to BWxFT (DAP(BWxFT)). The latter pairs contained less frequent procedure types with significant outliers. For DAP normalized to BW (DAP(BW)), 38% of the pairwise comparisons showed statistically significant differences. Conversion factors from DAP(BW) to OD and ED were reported for various weight groups, due to the higher correlation between DAP(BW) and both OD and ED than between DAP and both OD and ED. Conclusions : The P75 of DAP(BWxFT) for all procedures combined serves as an appropriate DRL value. This facilitates local DRL determination in smaller paediatric centres, which often have insufficient data to produce appropriate DRLs for different procedure types. Conversion factors are more reliable starting from DAP(BW) instead of DAP and should be used according to the appropriate BW group

Self-catheterization of urinary bladder complicated with extraperitoneal abscess that mimics an infected bladder diverticulum

AbstractFor patients who are suffering from neurogenic lower urinary tract dysfunction, intermittent urinary catheterization is an efficient way to empty the bladder.1 However, the method may result in various complications. Herein we present a rare complication of extraperitoneal abscess owing to intermittent urinary catheterization in a 62-year-old male who had cervical spine injury and was treated with intermittent urethral catheterization for neurogenic lower urinary tract dysfunction. Treatment and a literature review are also described

Transcatheter device closure of atrial septal defect and patent foramen ovale in Malta

Significant atrial septal defects (ASD) are closed, surgically or through a transcatheter device, in order to avoid pulmonary hypertension in late life. A patent foramen ovale (PFO) may need to be closed because of transient shunt reversal resulting in transient ischaemic events or stroke. We report the Maltese experience to date in transcatheter closure of these defects. A total of 46 ASDs and 51 PFOs have been successfully closed at our unit (total 97), with very low complication rates, rates that compare very favourably with results from larger international centres.peer-reviewe

Evaluating comfort measures for commonly performed painful procedures in pediatric patients.

Introduction: Management of pediatric pain from medical procedures is of great importance for improving both patient care and experience. In this study, we investigated methods of managing acute pain in infants and children by studying the correlation between the number of attempts to complete painful procedures, given different comfort measures. Methods: The study is a retrospective review of 74,276 procedures performed at two pediatric hospitals in an integrated academic children\u27s health system between 2013 and 2016. We compared three comfort measures most frequently offered: positions of comfort (POC), distraction (DIST), and pharmacological (PHARM). These methods were compared in the setting of four procedures: peripheral intravenous (PIV) catheter insertion, gastrointestinal tube placement, incision procedures, and bladder catheterization. We used the number of attempts needed to complete a procedure as a measure of efficacy minimizing distressing experience in an acutely painful setting (single attempt vs repeat attempts). Results: Among younger children, DIST appears superior to the other two methods; it performs significantly better for three of the four procedures (PIV catheterization, incision wound, and urinary catheterization) among infants agedchildren, POC tends to perform slightly better than the other two methods, although it is significantly better only for PIV catheterization among adolescents aged 13-21 years and urinary catheterization among children aged 9-12 years. Conclusion: Results from this study may be used to determine appropriate comfort measures for painful procedures in pediatric setting
