Abstract
BACKGROUND As a relatively new surgical technique, the learning curve of en bloc resection of bladder tumor (ERBT) in ex vivo models remains unaddressed. This study aimed to explore the learning curve of ERBT in an ex vivo porcine model. METHODS In this prospective study, eight endoscopists without prior experience in ERBT were divided into two groups: junior endoscopists, with less than 100 transurethral resection of bladder tumor (TURBT) procedure experience, and senior endoscopists, with at least 100 TURBT procedure experience. Each endoscopist performed 30 ERBT procedures on artificial lesions in an ex vivo porcine bladder model. The procedure time, perforation, en bloc resection status, and absence of detrusor muscle (DM) were recorded. The inflection points were identified using cumulative sum (CUSUM) analysis. Procedure results were compared between the two phases and two groups. RESULTS In all, 240 artificial lesions were successfully resected using ERBT. The CUSUM regression line indicated the inflection point at the 16th procedure for the junior endoscopists and at the 13th procedure for the senior endoscopists. In both groups, the procedure time, perforation, piecemeal resection, and DM absence rates were significantly lower in the consolidation phase than in the initial phase. The procedure time for the senior endoscopists was lower than for the junior endoscopists in both phases. CONCLUSIONS ERBT performance improved significantly after reaching the inflection point of the learning curve in the ex vivo model. We recommend a minimum of 16 ERBT procedures in ex vivo models for urologists with less than 100 TURBT experience and a minimum of 13 procedures for those with at least 100 TURBT experience before advancing to live animal training or supervised clinical practice.

Transurethral resection of bladder tumor: A systematic review of simulator-based training courses and curricula. Asian J Urol 2024; 11:1-9. [PMID: 38312823 PMCID: PMC10837651 DOI: 10.1016/j.ajur.2022.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 08/08/2022] [Indexed: 01/13/2023] Open
Abstract
Objective Transurethral resection of bladder tumor is one of the most common everyday urological procedures. This kind of surgery demands a set of skills that need training and experience. In this review, we aimed to investigate the current literature to find out if simulators, phantoms, and other training models could be used as a tool for teaching urologists. Methods A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement and the recommendations of the European Association of Urology guidelines for conducting systematic reviews. Fifteen out of 932 studies met our inclusion criteria and are presented in the current review. Results The UroTrainer (Karl Storz GmbH, Tuttlingen, Germany), a virtual reality training simulator, achieved positive feedback and an excellent face and construct validity by the participants. The inspection of bladder mucosa, blood loss, tumor resection, and procedural time was improved after the training, especially for inexperienced urologists and medical students. The construct validity of UroSim® (VirtaMed, Zurich, Switzerland) was established. SIMBLA simulator (Samed GmbH, Dresden, Germany) was found to be a realistic and useful tool by experts and urologists with intermediate experience. The test objective competency model based on SIMBLA simulator could be used for evaluating urologists. The porcine model of the Asian Urological Surgery Training and Education Group also received positive feedback by the participants that tried it. The Simulation and Technology Enhanced Learning Initiative Project had an extraordinary face and content validity, and 60% of participants would like to use the simulators in the future. The 5-day multimodal training curriculum "Boot Camp" in the United Kingdom achieved an increase of the level of confidence of the participants that lasted months after the project. Conclusion Simulators and courses or curricula based on a simulator training could be a valuable learning tool for any surgeon, and there is no doubt that they should be a part of every urologist's technical education.

Abstract
OBJECTIVES To assess the resection quality of transurethral bladder tumour resection (TURBT) and the association to surgeon experience depending on the presence of detrusor muscle. METHODS A retrospective study on 640 TURBT procedures performed at Zealand University Hospital, Denmark, from 1 January 2015 - 31 December 2016. Data included patient characteristics, procedure type, surgeon category, supervisor presence, surgical report data, pathological data, complications data and recurrence data. Analysis was performed using simple and multiple logistic regression on the association between surgeon experience and the presence of detrusor muscle in resected tissue from TURBT. RESULTS Supervised junior residents had significant lower detrusor muscle presence (73%) compared with consultants (83%) (OR = 0.4, 95% CI = 0.21-0.83). Limitations were the retrospective design and the diversity of included TURBT. CONCLUSIONS It was found that surgical experience predicts detrusor muscle presence and supervised junior residents performing TURBT on patients resulted in less detrusor muscle than consultants.

Abstract
BACKGROUND Competence in transurethral bladder tumour resection (TURB) is critical in bladder cancer management and should be ensured before independent practice. OBJECTIVE Develop an assessment tool for TURB and explore validity evidence in a clinical context. DESIGN, SETTING, AND PARTICIPANTS July 2019-March 2021, a total of 33 volunteer doctors from three hospitals were included. Participants performed two TURB procedures on patients with bladder tumours. A newly developed assessment tool (OSATURBS) was used for direct observation assessment, self-assessment, and blinded video-assessment. Outcome measurements and statistical analysis: Cronbach's alpha and Pearson's r were calculated for across items internal consistency reliability, inter-rater reliability, and test-retest reliability. Correlation between OSATURBS scores and the operative experience was calculated with Pearson's r and a pass/fail score was established. Differences in assessment scores were explored with paired t-test and independent samples t-test. RESULTS AND LIMITATIONS The internal consistency reliability across items Cronbach's alpha was 0.94 (n = 260, p < 0.001). Inter-rater reliability = 0.80 (n = 64, p < 0.001). Test-retest correlation was high, r = 0.71 (n = 32, p < 0.001). Relation to TURB experience was high, r = 0.71 (n = 32, p < 0.001). Pass/fail score = 19 points. Direct observation assessments were strongly correlated with video ratings (r = 0.85, p < 0.001) but with a significant social bias with lower scores for inexperienced and higher scores for experienced participants. Participants tended to overestimate their own performances. CONCLUSIONS OSATURBS assessment tool for TURB can be used for assessment of surgical proficiency in the clinical setting. Direct observation assessment and self-assessment are biased, and blinded video-assessment of TURB performances is advised.

Abstract
OBJECTIVE This systematic review aims to examine the use of standard-setting methods in the context of simulation-based training of surgical procedures. SUMMARY OF BACKGROUND Simulation-based training is increasingly used in surgical education. However, it is important to determine which level of competency trainees must reach during simulation-based training before operating on patients. Therefore, pass/fail standards must be established using systematic, transparent, and valid methods. METHODS Systematic literature search was done in four databases (Ovid MEDLINE, Embase, Web of Science, and Cochrane Library). Original studies investigating simulation-based assessment of surgical procedures with application of a standard setting were included. Quality of evidence was appraised using GRADE. RESULTS Of 24,299 studies identified by searches, 232 studies met the inclusion criteria. Publications using already established standard settings were excluded (N = 70), resulting in 162 original studies included in the final analyses. Most studies described how the standard setting was determined (N = 147, 91%) and most used the mean or median performance score of experienced surgeons (n = 65, 40%) for standard setting. We found considerable differences across most of the studies regarding study design, set-up, and expert level classification. The studies were appraised as having low and moderate evidence. CONCLUSION Surgical education is shifting towards competency-based education, and simulation-based training is increasingly used for acquiring skills and assessment. Most studies consider and describe how standard settings are established using more or less structured methods but for current and future educational programs, a critical approach is needed so that the learners receive a fair, valid and reliable assessment.

Abstract
PURPOSE OF REVIEW Conventional transurethral resection (TURBT) with tumor fragmentation is the primary step in the surgical treatment of nonmuscle invasive bladder cancer. Recently, new surgical techniques and training modalities have emerged with the aim to overcome short-comings of TURBT and improve oncologic outcomes. In this review, we provide a comprehensive update of recent techniques/techniques that aim to improve upon conventional TURBT and beyond. RECENT FINDINGS A systemic approach during conventional TURBT that features the use of a surgical checklist has been shown to improve recurrence-free survival. Several simulators have been developed and validated to provide additional training opportunities. However, transfer of improved simulator performance into real world surgery still requires validation. While there is no convincing data that demonstrate superior outcomes with bipolar TURBT, en-bloc resection already promises to offer lower rates of complications as well as potentially lower recurrence probabilities in select patients. SUMMARY TURBT remains the quintessential procedure for the diagnosis and treatment of bladder cancer. Urologists need to be aware of the importance and challenges of this procedure. Aside of embracing new resection techniques and a conceptual-systematic approach, training opportunities should be expanded upon to improve patient outcomes.

Abstract
PURPOSE OF REVIEW This review aims to summarize innovations in urologic surgical training in the past 5 years. RECENT FINDINGS Many assessment tools have been developed to objectively evaluate surgical skills and provide structured feedback to urologic trainees. A variety of simulation modalities (i.e., virtual/augmented reality, dry-lab, animal, and cadaver) have been utilized to facilitate the acquisition of surgical skills outside the high-stakes operating room environment. Three-dimensional printing has been used to create high-fidelity, immersive dry-lab models at a reasonable cost. Non-technical skills such as teamwork and decision-making have gained more attention. Structured surgical video review has been shown to improve surgical skills not only for trainees but also for qualified surgeons. Research and development in urologic surgical training has been active in the past 5 years. Despite these advances, there is still an unfulfilled need for a standardized surgical training program covering both technical and non-technical skills.
