Background: Quadriceps muscle layer thickness (QMLT), which is measured using ultrasound, is an emerging strategy to identify sarcopenia. Purpose: The purpose of the study was to assess whether pre-operative QMLT values are associated with a prolonged length of stay (LOS; defined as >14 days) following a renal transplant. Methods: Between March 2019 and January 2020, we performed a prospective study among patients undergoing renal transplantation. Physical Frailty scores and QMLT measurements were performed pre-operatively. The primary outcome was a greater LOS following transplant. Secondary outcomes included complications and renal function. Statistical analysis: Percentiles divided patients into two categories of QMLT (low and high). Continuous outcomes were compared using a two-sided t-test or Mann–Whitney U test, and Chi-square analysis and Fisher exact testing were used for nominal variables. Results: Of 79 patients, the frailty prevalence was 16%. Among patients with low and higher QMLTs, LOS of >14 days were 21% vs. 3% [p = 0.04], respectively. Demographically, there was a higher percentage of patients with living donors in the high- vs. low-QMLT groups (40 vs. 7%). However, in a subgroup analysis excluding living-donor recipients, the difference between groups was preserved (23% vs. 0%, p = 0.01). No differences in secondary outcomes were seen between groups. Conclusions: Low quadriceps muscle layer thickness may be associated with a prolonged length of stay for renal recipients. Further research is needed to confirm our findings. [ABSTRACT FROM AUTHOR]

Background: Mannitol and furosemide have been used as diuretics intraoperatively to facilitate early renal allograft function and reduce delayed graft function. As the evidence of any efficacy of these agents is limited, we sought to characterize the use of diuretics among transplant surgeons.Methods: An anonymous online survey was sent to all Canadian transplant programs where kidney transplants are routinely performed. Questions were related to the use and indications for mannitol and furosemide. Responses were collected and analyzed as counts and percentages of respondents. We used χ2 analysis to assess the relationship between demographic factors and survey responses.Results: Thirty-five surgeons completed the survey (response rate 50%). Seventy per cent of respondents reported performing 26 or more transplants per year, 88% had formal transplant fellowship training and 67% indicated that they currently train fellows. Only 24% and 12% reported believing that delayed graft function is reduced by mannitol and furosemide use, respectively. However, 73% routinely gave mannitol to patients and 53% routinely gave furosemide. The most common justification given for mannitol use was to induce diuresis (54%); 37% of respondents reported using mannitol because of training dogma. Likewise, 57% used furosemide for diuresis, with 23% reporting that their use of this agent was based on dogma. No relationship emerged between fellowship training, case volume or training program status and the use of any agent. Interestingly, 71% of respondents indicated that a randomized controlled trial evaluating the utility of intraoperative diuretics is needed and that they were interested in participating in such a trial.Conclusion: Use of intraoperative diuretics and the rationale for their use vary among surgeons. A substantial proportion of surgeons use these medications on the basis of dogma alone. A randomized controlled trial is needed to clarify the role of intraoperative diuretics in kidney transplant surgery. [ABSTRACT FROM AUTHOR]

Summary: The Canadian Association of Chairs of Surgical Research was created in 2014, with representation from every departmental surgical research committee across Canada, to establish Canadian surgical research as a beacon for health care innovation and to propose solutions for the daily challenges facing surgeon-researchers. Our key mandate has been to identify challenges for surgeons and scientists performing research to prevent further erosion of this vital area of activity that benefits patients, health care service providers and Canadian society. This article outlines the findings of a nationwide survey sent to all members of departments of surgery across Canada, seeking input on current threats and potential solutions. The results suggest that surgical research in Canada is experiencing a decline in funding and an increase in challenges affecting research productivity of academic surgeons, such as pressures to be clinically active, unpredictable surgical schedules, growing administrative demands, and increasing complexity of patient populations. Although surgeons are productive in their research endeavours, institutional changes and sharing of best practices are needed to ensure sustainable growth of research programs.

Summary: Kidney paired donation (KPD) programs are an effort to bridge the disparity between kidney supply and demand. These programs combine several incompatible donor-recipient pairs in a national paired exchange database, thereby increasing the number of compatible matches. But KPD programs face unique challenges, particularly the large distances that often separate donors and recipients. Here we discuss key factors to consider when transitioning from a donor travelling model to a kidney shipment model in the Canadian context. [ABSTRACT FROM AUTHOR]

Summary: Laparoscopic donor nephrectomy (LDN) is the gold standard for kidney donation. Recent literature has led to considerable debate regarding the safest route to provide vascular control during this procedure. The most common devices used for vascular control during LDN are staplers and surgical clips. Opinions regarding the safety of these devices vary, as both are prone to dysfunction. Certain clips have already been contraindicated for use on the donor artery owing to reports of catastrophic complications of falling off. Donor safety is paramount to the continued success of renal transplantation in Canada. A review of existing practice at each institution may be called for to ensure the safest standards possible are in place. An appendix to this commentary is available at canjsurg.ca.

Introduction: Physician burnout is associated with medical error, patient dissatisfaction, and poorer physician health. Urologists have reported high levels of burnout and poor work-life integration compared with other physicians. Burnout rates among Canadian urologists has not been previously investigated. We aimed to establish the prevalence of Canadian urologist burnout and associated factors. Methods: In the 2018 Canadian Urological Association census, the Maslach Burnout Inventory questions were assigned to all respondents. Responses from 105 practicing urologists were weighted by region and age group to represent 609 urologists in Canada. Burnout was defined as scoring high on the scales of emotional exhaustion or depersonalization. Demographic and practice variables were assessed to establish factors associated with burnout. Comparisons were made to the results of the 2016 American Urological Association census. Results: Overall, 31.8% of respondents met the criteria for burnout. There was no effect of subspecialty practice or practice setting on burnout. On univariate analysis, rates of burnout were highest among urologists under financial strain (50.8%), female urologists (45.3%), and early-to-mid-career urologists (37.7-41.8%). Factors associated with demanding practices and poor work-life integration were predictive of burnout. A total of 12.2% of urologists reported seeking burnout resources and 54.0% wished there were better resources available. Conclusions: Urologist burnout in Canada is lower than reported in other countries, but contributing factors are similar. Urologists who report demanding clinical practices (particularly in early-tomid career), poor work-life integration, financial strain, and female gender may benefit from directed intervention for prevention and management of burnout. Burnout resources for Canadian urologists require further development. [ABSTRACT FROM AUTHOR]

Introduction: The Royal College of Physicians and Surgeons of Canada's Competence by Design (CBD) initiative presents curricula challenges to ensure residents gain proficiency while progressing through training. To prepare first-year urology residents (R1s), we developed, implemented, and evaluated a didactic and simulationfocused boot camp to implement the CBD curriculum. We report our experiences and findings of the first three years. Methods: Urology residents from two Canadian universities participated in the two-day boot camp at the beginning of residency. Eleven didactic and six simulation sessions allowed for instruction and deliberate practice with feedback. Pre-and post-course multiple-choice questionnaires (MCQs) and an objective structured clinical exam (OSCE) evaluated knowledge and skills uptake. For initial program evaluation, three R2s served as historical controls in year 1. Results: Nineteen residents completed boot camp. The mean age was 26.4 (±2.8) and 13 were male. Participants markedly improved on the pre- and post-MCQs (year 1: 62% and 91%; year 2: 55% and 89%; year 3: 58% and 86%, respectively). Participants scored marginally higher than the controls on four of the six OSCE stations. OSCE scores remained >88% over the three cohorts. All participants reported higher confidence levels post-boot camp and felt it was excellent preparation for residency. Conclusions: During its first three years, our urology boot camp has demonstrated high feasibility and utility. Knowledge and technical skills uptake were established via MCQ and OSCE results, with participants' scores near or above those of R2 controls. This boot camp will remain in our CBD curriculum and can provide a framework for other urology residency programs. [ABSTRACT FROM AUTHOR]

While the urologist's involvement in kidney transplantation varies from center to center and country to country, urologists remain integral to many programs across Canada. From the early days of kidney transplant to contemporary times, the leadership, vision, and skillset of Canadian urologists have helped progress the field. In this review of Canadian urologists' role in kidney transplantation, the achievements of this professional group are highlighted and celebrated. Original contributors to the field, as well as notable achievements are highlighted, with a focus on the impact of Canadian urologists. [ABSTRACT FROM AUTHOR]

Introduction: The number of female medical students and physicians entering the workforce is increasing. Despite this trend, some surgical specialties are still considered male-dominant. Urology has a significant male predominance in both residency and independent practice. This male predominance could have an impact on the physician workforce, mentorship opportunities for females pursuing surgery, and on medical student attraction to urology as a specialty. Research conducted in the U.S. has shown that although fewer females enter the field of urology, acceptance rates between the two genders are similar. This study aims to identify if a trend towards gender-specific acceptance into urology residency exists within Canada. We also seek to identify if gender trends in acceptance to urology differ from other surgical specialties in Canada and assess the current workforce trends in Canadian urological practice. Methods: Canadian Residency Matching Services (CaRMS) data from the previous 10 years was analyzed. This data was accessed from the CaRMS website.1 Logistic regression analyses were used to assess if any significant difference exists between the rates of female and male applicant acceptance into urology. These rates were then compared to the rates of female and male acceptance into surgical residency as a whole and to specific surgical specialties, such as general surgery, orthopedics, and otolaryngology. Results: Within urology applicants, there is no evidence that the success rate over time between males and females differs (p=0.47). Within surgical residency applicants, there is no evidence that the success rate over time differs between male and female applicants (p=0.84). In comparing these two rates, there is also no significant difference between rates of acceptance to urology vs. surgery in general for female applicants (p=0.45). General surgery has a higher growth of females entering into the specialty compared to urology (p=0.016). Conversely, otolaryngology (p=0.123) and orthopedics (p=0.163) did not show a significant difference in the rates of female acceptance as compared to males over time. Our small sample size of 451 applicants over the 10-year time span (122 female, 329 male) could represent a limitation, however, we did ensure to analyze a 10-year sample to attempt to get an accurate representation of any trends. Conclusions: Our data identifies that there is no significant trend toward male acceptance into urology over female applicants. There is no significant difference related to female acceptance specifically into urology or any difference between rates of females accepted into urology as compared to all other surgical subspecialties combined.

Introduction: The Royal College of Physicians and Surgeons of Canada has begun implementing Competence by Design (CBD). However, it is unclear how much urology trainees and faculty know about CBD, their attitudes towards this change, and their willingness to embrace and participate in this new model of training. Methods: This cross-sectional study was conducted through an online survey, which was administered to all trainees and faculty at Canadian urology programs prior to the implementation of CBD. The final survey consisted of eight demographic questions, 17 fivepoint Likert items, one visual analog scale question, 11 multiplechoice questions, and two open-ended questions. Results: A total of 74 participants (38 faculty and 36 trainees) across 12 universities responded, with a completion rate of 82.4%. This corresponded to an overall response rate of 20.5%. Overall, there was a lack of resounding enthusiasm towards this shift to CBD in urology. Although both trainees and faculty had overall positive perceptions of CBD on assessment, teaching, and readiness, most agreed that this transition will be costly and associated with increased requirements for time, funding, and administrative support. Furthermore, there were significant concerns regarding the lack of valid assessment tools and evidence for the validity of entrustable professional activities. Conclusions: While this survey has demonstrated an appreciation for the benefits of CBD, challenges are equally anticipated. CBD in urology will be a fertile research area; this study has identified several important educational questions regarding the model's effectiveness and consequences, thus, providing collaborative opportunities among all Canadian programs.

Summary: "Never let a good crisis go to waste." - Sir Winston Churchill., The value of Canada's Kidney Paired Donation program to the population cannot be overstated. Its greatest challenge as a national program, however, is the geographic separation of recipient and matched donor. Representatives from every transplant program in the country have been working toward increased use of kidney shipping in order to diminish the disincentive of donor travel. With transplantation program and travel restrictions in place to minimize the risk of coronavirus disease 2019 (COVID-19), the time to make a full transition from donor travel to the shipment of donor kidneys has clearly arrived.
