RESUMO
PURPOSE: The effect of overactive bladder (OAB) on sexual health has been evaluated extensively for women but much less for men. Therefore, the aim of this study was to evaluate the relationship between OAB and men's sexual activity and the effect of OAB on erectile dysfunction (ED) and premature ejaculation (PE) in a large representative cohort of men at the population level. METHODS: This study was based on computer-assisted web interviews that used validated questionnaires. The most recent census and the sample size estimation calculations were employed to produce a population-representative pool. RESULTS: The study included 3001 men, representative of the population in terms of age and place of residence. The frequency of sexual intercourse was higher for respondents without OAB symptoms compared with persons who had OAB (p = 0.001), but there was no association between OAB symptoms and number of sexual partners (p = 0.754). Regression models did not confirm the effect of OAB on sexual activity (odds ratio 0.993, CI 0.974-1.013, p = 0.511). Both ED and PE were more prevalent in respondents with OAB symptoms compared with persons who lacked those symptoms (p < 0.001). Importantly, the effect of OAB on ED or PE was independent of age, comorbidities, and lifestyle habits (regression coefficients of 0.13 and 0.158 for ED and PE, respectively). CONCLUSION: Overactive bladder did not significantly affect men's sexual activity, but it significantly correlated with ED and PE. Our results suggest a need in daily clinical practice to screen for OAB symptoms for persons who report ED or PE.

INTRODUCTION: Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long-term outcomes. This systematic review will assess outcomes of SNM for treating CPP. METHODS: A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022. Studies using original data investigating SNM in an adult population with CPP which recorded pre and posttreatment pain scores were selected. Primary outcome was numerical change in pain score. Secondary outcomes were quality of life assessment and change in medication use and all-time complications of SNM. Risk of bias was assessed using the Newcastle Ottawa Tool for cohort studies. RESULTS: Twenty-six of 1026 identified articles were selected evaluating 853 patients with CPP. The implantation rate after test-phase success was 64.3%. Significant improvement of pain scores was reported in 13 studies; three studies reported no significant change. WMD in pain scores on a 10-point scale was -4.64 (95% confidence interval [CI] = -5.32 to -3.95, p < 0.00001) across 20 studies which were quantitatively synthesized: effects were maintained at long-term follow-up. Mean follow-up was 42.5 months (0-59). Quality of life was measured by RAND SF-36 and EQ-5D questionnaires and all studies reported improvement in quality of life. One hundred and eighty-nine complications were reported in 1555 patients (Clavien-Dindo Grade I-IIIb). Risk of bias ranged from low to high risk. Studies were case series and bias stemmed from selection bias and loss to follow-up. CONCLUSION: Sacral Neuromodulation is a reasonably effective treatment of Chronic Pelvic Pain and significantly reduces pain and increases patients' quality of life with immediate to long-term effects.

PURPOSE: The right gastric artery (RGA) supplies the lesser curvature of the stomach. The prevalence of variations in RGA origins can be of interests to students, surgeons, and radiologists who wish to increase their understanding of this vessel. The aim of this study was to perform a systematic review and meta-analysis on the origin of the RGA. METHODS: The PRISMA 2020 checklist was followed. Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched. There were no constraints based on language or publication status. Database search, data extraction and risk of bias assessment were performed independently by two authors. A random-effects meta-analysis of the prevalence of different RGA origins was conducted. RESULTS: A total of 9084 records were screened in the initial search. Fifteen studies were included, assessing 1971 right gastric arteries. The RGA arose most frequently from the Proper Hepatic Artery (PHA), with a pooled prevalence of 53.6% (95% CI 44.5-60.8%), followed by the Left Hepatic Artery (LHA) with a pooled prevalence of 25.9% (95% CI 18.6-32.8%), and the Gastroduodenal Artery (GDA) with a pooled prevalence of 8.89% (95% CI 4.62-13.9%). Less common origins were the Common Hepatic Artery (CHA) (6.86%, 95% CI 3.15-11.5%), the Right Hepatic Artery (RHA) (3.43%, 95% CI 0.93-7.04%), and Middle Hepatic Artery (MHA) (1.31%, 95% CI 0-3.44%). CONCLUSIONS: This meta-analysis provides an accurate estimate of the prevalence of different RGA origins. Anatomical knowledge combined with pre-operative planning and imaging can prevent iatrogenic injury during surgery.

PURPOSE: Urinary incontinence remains common in men after prostatectomy. Current guidance suggests early corrective surgery to those that are still incontinent after trying Pelvic Floor Muscle Therapy, however, other treatments are now available. This review aims to evaluate all currently available treatment options for men with post-prostatectomy incontinence (PPI). METHODS: A search of MEDLINE and CENTRAL databases on 2/2/2021 produced 879 articles. Any study evaluating incontinence before and after a treatment protocol was eligible for inclusion. After screening, 17 randomized control trials were included, and pre-defined data points were collected. Due to heterogeneity, pooled analysis was not possible, and a descriptive synthesis was produced in accordance with PRISMA guidelines. Cochrane Risk of Bias (RoB) tool was used to evaluate all studies. The search protocol and methods for this study was registered on the PROSPERO database before the search began, ID:(CRD42021229749). RESULTS: 3/17(18%) of studies focussed on pharmacotherapy, 2/17(12%) on vibration therapies, 8/17(47%) on pelvic floor muscle therapy (PFMT), 3/17(18%) on electrical stimulation (ES), and 1/17 (6%) on extracorporeal magnetic innervation (ExMI) as their main intervention. The use of Duloxetine, Solifenacin, PFMT, ES, and ExMI all show effective reduction in incontinence in men suffering from PPI. No study in this review evaluated surgical managements for PPI. CONCLUSION: A large number of treatments are available for PPI using an array of different methods. For this reason, a variety of treatments could be considered before early invasive procedures, to prevent unnecessary surgery and its associated negative complications.

OBJECTIVE: In the last decade non-technical skills (NTS) have emerged as a vital area for improvement within surgery. This study aims to develop and evaluate a Non-technical Skills for Urological Surgeons (NoTSUS) training curriculum and assessment scale. METHODS: This international, longitudinal and observational study began with a 3-round Delphi methodology to refine curriculum contents and rating scale. Sessions with up to four participants were delivered where each candidate undertook an independent scenario within the validated full immersion simulation environment. Candidates were assessed using both the NoTSS (Non-technical Skills for Surgeons) and NoTSUS rating scales by NTS-trained and non-trained experts. A post-training evaluation survey was distributed. RESULTS: 62 participants comprising trainees (n = 43) and specialists (n = 19) undertook the NoTSUS course. The NoTSS and NoTSUS scales correlated well, with a mean difference of 3.3 in the overall total (p = 0.10, r = 0.53). However, there was significant differences in scores between the NoTSS-trained and non-trained raters (n = 28, p = 0.03). A one-way ANOVA test revealed significant improvement throughout the four simulation scenarios in each session (p = 0.02). The NoTSUS curriculum received positive feedback from participants and demonstrated educational value and acceptability. CONCLUSIONS: The NoTSUS curriculum has demonstrated high educational value for NTS training aimed at urologists, with marked improvement throughout sessions. Correlation of NoTSUS and NoTSS scales proves its suitability for evaluating NTS in future training. Demonstration of inter-rater reliability indicates that the scale is reliable for use in assessment by expert faculty members. Furthermore, qualitative feedback from participants suggests gain of transferrable skills over the course.

OBJECTIVE: Different simulation modalities may be utilised in a curricular fashion to benefit from the strengths of each training model. The aim of this study is to evaluate a novel multi-modality ureterorenoscopy (URS) simulation curriculum in terms of educational value, content validity, transfer of skills and inter-rater reliability. METHODS: This international prospective study recruited urology residents (n = 46) with ≤ 10 URS experience and no prior simulation training. Participants were guided through each phase of the expert-developed SIMULATE URS curriculum by trainers and followed-up in the operating room (OR). Video recordings were obtained during training. A post-training evaluation survey was distributed to evaluate content validity and educational value, using descriptive statistics. Performance was evaluated using the objective structured assessment of technical skills (OSATS) scale to measure improvement in scores throughout the curriculum. Pearson's correlation coefficient and Cohen's kappa tests were utilised to investigate correlation and agreement between raters. RESULTS: Participants reported gaining OR-transferrable skills (Mean: 4.33 ± 0.67) and demonstrated marked improvement in throughout the curriculum, transferred to the OR for both semi-rigid URS (p = 0.004) and flexible URS (p = 0.007). 70% of participants were successfully followed-up in the OR (n = 32). No differences were identified with the additional use of fresh frozen cadavers (p = 0.85, p = 0.90) and the URO Mentor VR simulator (p = 0.13, p = 0.22). A moderate level of correlation was noted on the video OSATS assessments, between two expert assessors (r = 0.70), but a poor agreement with the live rating. CONCLUSION: The SIMULATE URS training curriculum received high educational value from participants, who demonstrated statistically significant improvement with consecutive cases throughout the curriculum and transferability of skills to the OR in both semi-rigid and flexible URS.

BACKGROUND: Virtual reality (VR) training is widely used for surgical training, supported by comprehensive, high-quality validation. Technological advances have enabled the development of procedural-based VR training. This study assesses the effectiveness of procedural VR compared to basic skills VR in minimally invasive surgery. METHODS: 26 novice participants were randomised to either procedural VR (n = 13) or basic VR simulation (n = 13). Both cohorts completed a structured training programme. Simulator metric data were used to plot learning curves. All participants then performed parts of a robotic radical prostatectomy (RARP) on a fresh frozen cadaver. Performances were compared against a cohort of 9 control participants without any training experience. Performances were video recorded and assessed blindly using GEARS post hoc. RESULTS: Learning curve analysis demonstrated improvements in technical skill for both training modalities although procedural training was associated with greater training effects. Any VR training resulted in significantly higher GEARS scores than no training (GEARS score 11.3 ± 0.58 vs. 8.8 ± 2.9, p = 0.002). Procedural VR training was found to be more effective than both basic VR training and no training (GEARS 11.9 ± 2.9 vs. 10.7 ± 2.8 vs. 8.8 ± 1.4, respectively, p = 0.03). CONCLUSIONS: This trial has shown that a structured programme of procedural VR simulation is effective for robotic training with technical skills successfully transferred to a clinical task in cadavers. Further work to evaluate the role of procedural-based VR for more advanced surgical skills training is required.

Objective. Motor imagery (MI) is widely used to improve technical skills in sports and has been proven to be effective in neurorehabilitation and surgical education. This review aims to identify the key characteristics of MI protocols for implementation into surgical curricula. Design. This study is a systematic review and meta-analysis. PubMed, MEDLINE, Embase and PsycINFO databases were systematically searched. The primary outcome was the impact of MI training on measured outcomes, and secondary outcomes were study population, MI intervention characteristics, study primary outcome measure and subject rating of MI ability (systematic review registration: PROSPERO CRD42019121895). Results. 456 records were screened, 60 full texts randomising 2251 participants were reviewed and 39 studies were included in meta-analysis. MI was associated with improved outcome in 35/60 studies, and pooled analysis also showed improved outcome on all studies with a standardised mean difference of .39 (95% CI: .12, .67, P = .005). In studies where MI groups showed improved outcomes, the median duration of training was 24 days (mode 42 days), and the median duration of each individual MI session was 30 minutes (range <1 minute-120 minutes). Conclusions. MI training protocols for use in surgical education could have the following characteristics: MI training delivered in parallel to existing surgical training, in a flexible format; inclusion of a brief period of relaxation, followed by several sets of repetitions of MI and a refocusing period. This is a step towards the development of a surgical MI training programme, as a low-cost, low-risk tool to enhance practical skills.

PURPOSE: With non-technical skills (NTS) deficits being recognised as a major cause for error in surgery, there is an increasing interest in their training and evaluation. A growing number of training courses are emerging and some NTS curricula have also been created. Many different training methods are described in the literature but there is still uncertainty with regards to their optimum combination within a curriculum. METHODS: A literature review of the electronic database Medline was performed. All articles published before December 2018 were screened by abstract and included if deemed relevant by the author. The included articles' reference lists were also screened for further relevant studies. RESULTS: Simulation training is accepted as the most effective way to train NTS. Within simulation training, it is shown that the 'igloo' full immersion/distributed simulation environment is appropriate for teaching NTS in urological scenarios where a designated operating room or space is not available. The use of multiple settings, for example wards and clinics as well as the operating room, is advantageous, as is training in an interprofessional team. Classroom teaching also plays a role in NTS training as an adjunct to simulation, with evidence that it improves some parameters of NTS. All levels, including qualified surgeons, benefit from NTS training; however, adaptation to both trainee level and specialty is important. Although less time consuming, training juniors and seniors together mainly benefits juniors, and training NTS at the same time as technical skills detracts from the quality of teaching. Debriefing is an important part of training and should be well structured; there are many debriefing models in existence, allowing for choice of method based on examiner preference and participant demographic. Furthermore, examiners should be well briefed in their task and trained in NTS assessment. CONCLUSION: To move forward, studies should combine tried and tested learning techniques into a curriculum covering all training levels, which should then be validated and followed up long term to ensure a positive impact on patient safety.

BACKGROUND: Tools for assessment of technical skills are a crucial part of surgical education. They provide trainees with quantitative feedback highlighting both proficiency and areas for improvement. For this to be relevant to day-to-day practice, the tools used have to be validated and relevant to each surgical situation. This study aims to evaluate the validity of assessment tools used within surgery. MATERIALS AND METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, a systematic review was conducted searching the MEDLINE and Embase databases (International Prospective Register of Systematic Reviews: CRD42018104674). Studies utilizing any assessment tool in any surgical specialty were included. Messick's criteria were used for literature evaluation, and the Modified Educational Oxford Centre for Evidence-Based Medicine was used to assess levels of recommendation. RESULTS: A total of 303 studies and 76 tools were included. The most commonly used tool was Objective Structured Assessment Tool Skills (OSATS; n = 137, 45.2%). OSATS was used in conjunction with another tool or tools in an additional 55 studies (18.2%). Seven further tools were used in at least 3 studies. A total of five studies evaluated contained all five aspects of Messick's validity. CONCLUSIONS: There are several widely validated tools for assessing technical skills, the most common of which is OSATS. There is an emerging trend for crowdsourcing as a quick, cheap method for assessment of technical skills. This technique has been validated using both GEARS and GOALS. Numerous tools were found to be used only once and demonstrate a tendency for units to create their own tools for a specific task or specialty.

OBJECTIVES: To develop a wet laboratory training model for learning core laparoscopic surgical skills and evaluating learners' competency level outside the operating room. METHODS: Participants completed three tasks (task 1: tissue dissection around the aorta; task 2: tissue dissection and division of the renal artery; task 3: renal parenchymal closure). Each performance was video recorded and subsequently evaluated by two experts, according to the Global Operative Assessment of Laparoscopic Skills and task-specific metrics that we developed (Assessment Sheet of Laparoscopic Skills in Wet Lab score). Mean scores were used for analyses. The subjective mental workload was also assessed (NASA Task Load Index). RESULTS: The 54 participants included 32 urologists, eight young trainees and 14 medical students. A total of 13 participants were categorized as experts (≥50 laparoscopic surgeries), eight as intermediates (10-49) and 33 as novices (0-9). There were significant differences in the Global Operative Assessment of Laparoscopic Skills and Assessment Sheet of Laparoscopic Skills in Wet Lab scores among the three groups in all three tasks. Higher NASA Task Load Index scores were observed in novices, and there were significant differences in tasks 1 (Kruskal-Wallis test, P = 0.0004) and 2 (P = 0.0002), and marginal differences in task 3 (P = 0.0745) among the three groups. CONCLUSIONS: Our training model has good construct validity, and differences in the NASA Task Load Index score reflect previous laparoscopic surgical experiences. Our findings show the ability to assess both laparoscopic surgical skills and mental workloads, which could help educators comprehend trainees' level outside the operating room. Given the decreasing opportunity to carry out pure laparoscopic surgeries because of the dissemination of robotic surgery, especially in urology, our model can offer practical training opportunities.

BACKGROUND: Difficult surgical procedures may result in a higher mental workload, leading to increased fatigue and subsequent errors. This study was aimed to investigate the effect of repeated simulation training in ureterorenoscopy in a high-fidelity setting on the performance and mental workload of novice operators. METHODS: Medical students voluntarily participated in the present simulation study. After a didactic and video-based lecture, they underwent simulation training involving a renal stone case, including a rigid cystoscope component (task 1, performing a WHO checklist, assembling a scope, and insertion of a guide-wire and an access sheath after examining the bladder) and a flexible ureterorenoscope component (task 2, retrieving a stone located in the upper calyx using a basket after inspecting the upper, middle, and lower calyx). Training was performed in a mock operating theater. Technical skills were assessed by one author (an experienced urologist) onsite using an Objective Structured Assessment of Technical Skills (OSATS) score at each training session. The mental workload was subjectively evaluated by the National Aeronautics and Space Administration Task Load Index (NASA-TLX) questionnaire after each training session. RESULTS: Seventeen students completed a minimum of 6 training sessions (male: female = 10: 7, median age of 22) over a median of 21 days (range, 10-32). In both tasks 1 and 2, the OSATS score improved over the 6 sessions with evidence of plateauing (MANOVA model, task 1: p < 0.0001, task 2: p < 0.0001). In contrast, the NASA-TLX score persistently decreased without plateauing (task 1: p = 0.0005, task 2: p = 0.0028). CONCLUSIONS: Under repeated simulation training in ureterorenoscopy in a high-fidelity setting, participants showed a continual decrease of the mental workload, while the improvement of technical skills reached a plateau over the 6 sessions. Our study showed the important benefit of simulation training to reduce the mental workload by repeated scenario training before actual clinical practice.

We aimed to assess male circumcision for the prevention of human immunodeficiency virus (HIV) acquisition in heterosexual and homosexual men using all available data. A systematic literature review was conducted searching for studies that assessed male circumcision as a method to prevent HIV acquisition in homosexual and/or heterosexual men. PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL) and ClinicalTrials.gov were searched in March 2017. A random effects model was used to calculate a pooled risk ratio (RR) and its associated 95% confidence interval (CI). In total, 49 studies were included in this meta-analysis. The overall pooled RR for both homosexual and heterosexual men was 0.58 (95% CI 0.48-0.70), suggesting that circumcision was associated with a reduction in HIV risk. Circumcision was found to be protective for both homosexual and heterosexual men (RR: 0.80, 95% CI 0.69-0.92 and 0.28, 95% CI 0.14-0.59, respectively). Heterosexual men had a greater RR reduction (72% compared with 20% for homosexual men). There was significant heterogeneity among the studies (χ2 = 1378.34, df = 48; I2 = 97%). This meta-analysis shows that male circumcision was effective in reducing HIV risk for both heterosexual and homosexual men.

OBJECTIVE: To investigate the effectiveness of motor imagery (MI) for technical skill and non-technical skill (NTS) training in minimally invasive surgery (MIS). SUBJECTS AND METHODS: A single-blind, parallel-group randomised controlled trial was conducted at the Vattikuti Institute of Robotic Surgery, King's College London. Novice surgeons were recruited by open invitation in 2015. After basic robotic skills training, participants underwent simple randomisation to either MI training or standard training. All participants completed a robotic urethrovesical anastomosis task within a simulated operating room. In addition to the technical task, participants were required to manage three scripted NTS scenarios. Assessment was performed by five blinded expert surgeons and a NTS expert using validated tools for evaluating technical skills [Global Evaluative Assessment of Robotic Skills (GEARS)] and NTS [Non-Technical Skills for Surgeons (NOTSS)]. Quality of MI was assessed using a revised Movement Imagery Questionnaire (MIQ). RESULTS: In all, 33 participants underwent MI training and 29 underwent standard training. Interrater reliability was high, Krippendorff's α = 0.85. After MI training, the mean (sd) GEARS score was significantly higher than after standard training, at 13.1 (3.25) vs 11.4 (2.97) (P = 0.03). There was no difference in mean NOTSS scores, at 25.8 vs 26.4 (P = 0.77). MI training was successful with significantly higher imagery scores than standard training (mean MIQ score 5.1 vs 4.5, P = 0.04). CONCLUSIONS: Motor imagery is an effective training tool for improving technical skill in MIS even in novice participants. No beneficial effect for NTS was found.

BACKGROUND: With the increased use of simulation for surgical training, there is a need for objective forms of assessment to evaluate trainees. The Global Evaluative Assessment of Robotic Skills (GEARS) is widely used for assessing skills in robotic surgery, but there are no recognised checklist scoring systems. This study aimed to develop a checklist for suturing in robotic surgery. METHODS: A suturing checklist for needle driving and knot tying was constructed following evaluation of participants performing urethrovesical anastomoses. Key procedural steps were identified from expert videos, while assessing novice videos allowed identification of common technical errors. 22 novice and 13 expert videos were marked on needle driving, while 18 novices and 10 experts were assessed on knot tying. Validation of the finalised checklist was performed with the assessment of 39 separate novices by an expert surgeon and compared to GEARS scoring. RESULTS: The internal consistency of the preliminary checklist was high (Cronbach's alpha = 0.870 for needle driving items; 0.736 for knot tying items), and after removal of poorly correlating items, the final checklist contained 23 steps. Both the needle driving and knot tying categories discriminated between novices and experts, p < 0.005. While the GEARS score demonstrated construct validity for needle driving, it could not significantly differentiate between novices and experts for knot tying, p = 0.286. The needle driving category significantly correlated with the corresponding GEARS scores (rs = 0.613, p < 0.005), but the correlation for knot tying was insignificant (rs = 0.296, p = 0.127). The pilot data indicates the checklist significantly correlated with the GEARS score (p < 0.005). CONCLUSION: This study reports the development of a valid assessment tool for suturing in robotic surgery. Given that checklists are simple to use, there is significant scope for this checklist to be used in surgical training.

RESUMO
BACKGROUND: Ureteropelvic junction obstruction (UPJO) is characterised by an obstruction compromising the passage of urine from the renal pelvis into the ureter, and can be corrected by Robot-Assisted Laparoscopic Pyeloplasty (RALP). We aimed to evaluate the surgical outcomes of RALP, and examine the rates of true pain resolution following the procedure. METHODS: We retrospectively explored the records of all patients who underwent RALP between April 2005 and January 2017. Measures of success were defined as the prevention of deterioration in split renal function and resolution of obstruction, and the resolution or improvement in subjective pain levels. RESULTS: 83 patients were included in this series. Mean patient age was 40.8 years. 38 patients had a left sided RALP, whilst 45 underwent RALP on the right. Crossing vessels were identified in 53.0% of patients. Mean operative time was 148.0 min. 68 patients had pain as their presenting feature. Following RALP, the pain resolved in 69.2% (n = 47), improved in 26.5% (n = 18), and remained the same in 4.4% (n = 3). 11.8% (n = 8) of patients required referral to other specialities for pain management. Success from a radiological perspective of cleared obstruction and arrest of deteriorating renal function was 97.6%. CONCLUSIONS: Our individual outcomes demonstrate a high success rate regarding resolution of obstruction and preventing deterioration in renal function. We also report that a number of patients, who despite meeting the radiological criteria to undergo RALP, had alternate underlying causes for their pain symptoms. For this reason, we propose that the primary measure of success for RALP should be based on renal function and radiological outcomes, rather than the outcomes relating to pain. Both surgeons and patients should be aware that whilst RALP is a highly successful procedure, persistence of pain may be due to overlapping clinical conditions which can be managed by a multidisciplinary approach.

BACKGROUND: To establish objective benchmarks at the level of a competent robotic surgeon across different exercises and metrics for the RobotiX Mentor virtual reality (VR) simulator suitable for use within a robotic surgical training curriculum. METHODS: This retrospective observational study analysed results from multiple data sources, all of which used the RobotiX Mentor VR simulator. 123 participants with varying experience from novice to expert completed the exercises. Competency was established as the 25th centile of the mean advanced intermediate score. Three basic skill exercises and two advanced skill exercises were used. SETTING: King's College London. PARTICIPANTS: 84 Novice, 26 beginner intermediates, 9 advanced intermediates and 4 experts were used in this retrospective observational study. RESULTS: Objective benchmarks derived from the 25th centile of the mean scores of the advanced intermediates provided suitably challenging yet also achievable targets for training surgeons. The disparity in scores was greatest for the advanced exercises. Novice surgeons are able to achieve the benchmarks across all exercises in the majority of metrics. CONCLUSION: We have successfully created this proof-of-concept study, which requires validation in a larger cohort. Objective benchmarks obtained from the 25th centile of the mean scores of advanced intermediates provide clinically relevant benchmarks at the standard of a competent robotic surgeon that are challenging yet also attainable. That can be used within a VR training curriculum allowing participants to track and monitor their progress in a structured and progressional manner through five exercises. Providing clearly defined targets, ensuring that a universal training standard has been achieved across training surgeons.

In the pre-targeted therapy era, palliative cytoreductive nephrectomy combined with cytokine immunotherapy was the standard treatment protocol for the management of metastatic renal cell carcinoma. The introduction of targeted therapies has improved response rates, median survival and overall prognosis when compared to immunotherapy. The role of cytoreductive nephrectomy in providing an independent survival advantage when used alongside immunotherapy has been demonstrated by two randomised controlled trials. However, with the new shift in improved treatment outcomes from cytokine immunotherapy to targeted therapies, the continuing role of cytoreductive nephrectomy as a viable surgical treatment method remains controversial.
