International consensus panel for transurethral resection of bladder tumours metrics: assessment of face and content validity.

OBJECTIVE: To develop performance metrics that objectively define a reference approach to a transurethral resection of bladder tumours (TURBT) procedure, seek consensus on the performance metrics from a group of international experts. METHODS: The characterisation of a reference approach to a TURBT procedure was performed by identifying phases and explicitly defined procedure events (i.e., steps, errors, and critical errors). An international panel of experienced urologists (i.e., Delphi panel) was then assembled to scrutinise the metrics using a modified Delphi process. Based on the panel's feedback, the proposed metrics could be edited, supplemented, or deleted. A voting process was conducted to establish the consensus level on the metrics. Consensus was defined as the panel majority (i.e., >80%) agreeing that the metric definitions were accurate and acceptable. The number of metric units before and after the Delphi meeting were presented. RESULTS: A core metrics group (i.e., characterisation group) deconstructed the TURBT procedure. The reference case was identified as an elective TURBT on a male patient, diagnosed after full diagnostic evaluation with three or fewer bladder tumours of ≤3 cm. The characterisation group identified six procedure phases, 60 procedure steps, 43 errors, and 40 critical errors. The metrics were presented to the Delphi panel which included 15 experts from six countries. After the Delphi, six procedure phases, 63 procedure steps, 47 errors, and 41 critical errors were identified. The Delphi panel achieved a 100% consensus. CONCLUSION: Performance metrics to characterise a reference approach to TURBT were developed and an international panel of experts reached 100% consensus on them. This consensus supports their face and content validity. The metrics can now be used for a proficiency-based progression training curriculum for TURBT.

Risk factors of early infectious complications after ureterorenoscopy for stone disease: a prospective study.

PURPOSE: To prospectively evaluate the rate and associated risk factors of early infectious complications after ureterorenoscopy for urolithiasis. METHODS: After ethical committee approval, 400 therapeutic retrograde ureterorenoscopy procedures between August 3, 2020 and November 24, 2021 were included for analysis in a single-center study. Postoperative infection was defined as an afebrile urinary tract infection, fever (≥ 38 °C) with pyuria (≥ 300 WBC/µL) or proven urinary pathogen, and urosepsis. The primary outcome was the rate of infectious complications after ureterorenoscopy. Secondary outcomes were the perioperative factors that increased the risk of infectious complications within 30 days of surgery using univariate and multivariate logistic regression analysis. RESULTS: Twenty-nine of four hundred (7.3%) patients developed an infectious complication within 30 days after ureterorenoscopy. Ten (2.5%) patients developed an afebrile urinary tract infection, eight (2.0%) developed fever with pyuria, five (1.3%) febrile urinary tract infection, and six (1.5%) urosepsis. On univariate analysis, preoperative stent-type JFil® pigtail suture stent was significantly associated with the dependent variable (p < 0.001). On multivariate logistic regression analysis, older age (OR 1.035; 95% CI 1.006-1.070; p = 0.02) was found to be significantly associated with developing a postoperative infectious complication. CONCLUSIONS: A 7.3% rate of postoperative infectious complications and 1.5% urosepsis rate were observed after therapeutic ureterorenoscopy, without the need of intensive care admission. The only significant risk factors were preoperative stent type (JFil® pigtail suture stent) on univariate analysis, and older age on multivariate logistic regression analysis. Further multicentric prospective observational data are needed in this field.

Proficiency-based progression training for robotic surgery skills training: a randomized clinical trial.

OBJECTIVE: To determine whether proficiency-based progression (PBP) training leads to better robotic surgical performance compared to traditional training (TT), given that the value of PBP training for learning robotic surgical skills is unclear. MATERIALS AND METHODS: The PROVESA trial is a multicentric, prospective, randomized and blinded clinical study comparing PBP training with TT for robotic suturing and knot-tying anastomosis skills. A total of 36 robotic surgery-naïve junior residents were recruited from 16 training sites and 12 residency training programmes. Participants were randomly allocated to metric-based PBP training or the current standard of care TT, and compared at the end of training. The primary outcome was percentage of participants reaching the predefined proficiency benchmark. Secondary outcomes were the numbers of procedure steps and errors made. RESULTS: Of the group that received TT, 3/18 reached the proficiency benchmark versus 12/18 of the PBP group (i.e. the PBP group were ~10 times as likely to demonstrate proficiency [P = 0.006]). The PBP group demonstrated a 51% reduction in number of performance errors from baseline to the final assessment (18.3 vs 8.9). The TT group demonstrated a marginal improvement (15.94 vs 15.44) in errors made. CONCLUSIONS: The PROVESA trial is the first prospective randomized controlled trial on basic skills training in robotic surgery. Implementation of a PBP training methodology resulted in superior surgical performance for robotic suturing and knot-tying anastomosis performance. Compared to TT, better surgical quality could be obtained by implementing PBP training for basic skills in robotic surgery.

A novel tool to predict functional outcomes after robot-assisted radical prostatectomy and the value of additional surgery for incontinence.

OBJECTIVES: To develop and validate a model to predict 12-month continence status after robot-assisted radical prostatectomy (RARP) from preoperative and 3-month postoperative data; this model could help in informing patients on their individualised risk of urinary incontinence (UI) after RP in order to choose the best treatment option. PATIENTS AND METHODS: Data on 9421 patients in 25 Belgian centres were prospectively collected (2009-2016) in a compulsory regional database. The primary outcome was the prediction of continence status, using the International Consultation on Incontinence Urinary Incontinence Short Form (ICIQ-UI-SF) at 12-months after RARP. Linear regression shrinkage was used to assess the association between preoperative 3-month postoperative characteristics and 12-month continence status. This association was visualised using nomograms and an online tool. RESULTS: At 12 months, the mean (sd) score of the ICIQ-UI-SF questionnaire was 4.3 (4.7), threefold higher than the mean preoperative score of 1.4. For the preoperative model, high European Association of Urology risk classification for biochemical recurrence (estimate [Est.] 0.606, se 0.165), postoperative radiotherapy (Est. 1.563, se 0.641), lower preoperative European Organisation for Research and Treatment of Cancer quality of life questionnaire 30-item core (EORCT QLQ-C30)/quality of life (QoL) score (Est. -0.011, se 0.003), higher preoperative ICIQ-UI-SF score (Est 0.214, se 0.018), and older age (Est. 0.058, se 0.009), were associated with a higher 12-month ICIQ-UI-SF score. For the 3-month model, higher preoperative ICIQ-UI-SF score (Est. 0.083, se 0.014), older age (Est. 0.024, se 0.007), lower 3-month EORCT QLQ-C30/QoL score (Est. -0.010, se 0.002) and higher 3-month ICIQ-UI-SF score (Est. 0.562, se 0.009) were associated with a higher 12-month ICIQ-UI-SF score. CONCLUSIONS: Our models set the stage for a more accurate counselling of patients. In particular, our preoperative model assesses the risk of UI according to preoperative and early postoperative variables. Our postoperative model can identify patients who most likely would not benefit from conservative treatment and should be counselled on continence surgery.

Evaluation of the "Teaching Guide for Basic Laparoscopic Skills" as a stand-alone educational tool for hands-on training sessions: a pilot study.

INTRODUCTION AND OBJECTIVES: Standardization of hands-on training (HoT) has profoundly impacted the educational field in the last decade. To provide quality training sessions on a global scale, the European School of Urology Training group developed a teaching guide for tutors in 2015. Our study aims to understand whether this guide alone can provide information enough to match the performance improvement guaranteed by an expert tutor. MATERIAL AND METHODS: 4 randomized groups of participants underwent HoT sessions with different teaching modalities: an expert surgeon (group 1), an expert E-BLUS tutor (group 2), E-BLUS guide alone (group 3), no tutor (group 4). Groups 1 and 2 were respectively provided with two different tutors to avoid biases related to personal tutor ability. Along the training session, each participant could perform five trials on two E-BLUS tasks: Peg transfer and Knot tying. During trials 1 and 5, completion time and number of errors were recorded for analysis with Pi-score algorithm. The average per-group Pi-scores were then compared to measure different performance improvement results. RESULTS: 60 participants from Italy were enrolled and randomized into four groups of 15. Pi-scores recorded on Peg transfer task were 24,6 (group 1), 26,4 (group 2), 42,2 (group 3), 11,7 (group 4). Pi-scores recorded on Knot tying task were 33,2 (group 1), 31,3 (group 2), 37,5 (group 3), 18,6 (group 4). CONCLUSION: Compared to a human tutor, standardized teaching with the EBLUS guide may produce similar performance improvement. This evidence opens doors to automated teaching and to several novelties in hands-on training.

Evaluation of a remote-controlled laparoscopic camera holder for basic laparoscopic skills acquisition: a randomized controlled trial.

BACKGROUND: Unsteady camera movement and poor visualization contribute to a difficult learning curve for laparoscopic surgery. Remote-controlled camera holders (RCHs) aim to mitigate these factors and may be used to overcome barriers to learning. Our aim was to evaluate performance benefits to laparoscopic skill acquisition in novices using a RCH. METHODS: Novices were randomized into groups using a human camera assistant (HCA) or the FreeHand v1.0 RCH and trained in the (E-BLUS) curriculum. After completing training, a surgical workload questionnaire (SURG-TLX) was issued to participants. RESULTS: Forty volunteers naïve in laparoscopic skill were randomized into control and intervention groups (n = 20) with intention-to-treat analysis. Each participant received up to 10 training sessions using the E-BLUS curriculum. Competency was reached in the peg transfer task in 5.5 and 7.6 sessions for the ACH and HCA groups, respectively (P = 0.015), and 3.6 and 6.8 sessions for the laparoscopic suturing task (P = 0.0004). No significance differences were achieved in the circle cutting (P = 0.18) or needle guidance tasks (P = 0.32). The RCH group experienced significantly lower workload (P = 0.014) due to lower levels of distraction (P = 0.047). CONCLUSIONS: Remote-controlled camera holders have demonstrated the potential to significantly benefit intra-operative performance and surgical experience where camera movement is minimal. Future high-quality studies are needed to evaluate RCHs in clinical practice. TRIAL REGISTRATION: ISRCTN 83733979.

Validation of the endoscopic stone treatment step 1 (EST-s1): a novel EAU training and assessment tool for basic endoscopic stone treatment skills-a collaborative work by ESU, ESUT and EULIS.

INTRODUCTION: The endoscopic stone treatment step 1 (EST s1) protocol has been developed after 2 years of collaborative work between different European Association of Urology (EAU) sections. OBJECTIVES: In this study, we added construct validity evidence to the EST s1 curriculum. MATERIALS AND METHODS: The EST-s1 curriculum includes four standardized tasks: flexible cystoscopy, rigid cystoscopy, semi-rigid URS and flexible URS. Validation was performed during the annual 2016 EUREP meeting in Prague. 124 participants provided information on their endoscopic logbook and carried out these 4 tasks during a DVD recorded session. Recordings were anonymized and blindly assessed independently by five proctors. Inter-rater reliability was checked on a sample of five videos by the calculation of intra-class correlation coefficient. Task-specific clinical background of participants was correlated with their personal performance on the simulator. Breakpoint analysis was used to define the minimum number of performed cases, to be considered "proficient". "Proficient" and "Non-proficient" groups were compared for construct validity assessment. Likert scale-based questionnaires were used to test content and to comment on when the EST-s1 exams should be undertaken within the residency program. RESULTS: 124 participants (105 final-year residents and 19 faculty members) took part in this study. The breakpoint analysis showed a significant change in performance curve at 36, 41, 67 and 206 s, respectively, corresponding to 30, 60, 25 and 120 clinical cases for each of the 4 tasks. EST-s1 was scored as a valid training tool, correctly representing the procedures performed in each task. Experts felt that this curriculum is best used during the third year of residency training. CONCLUSION: Our validation study successfully demonstrated correlation between clinical expertise and EST-s1 tasks, adding construct validity evidence to it. Our work also demonstrates the successful collaboration established within various EAU sections.

Performance Improvement (Pi) score: an algorithm to score Pi objectively during E-BLUS hands-on training sessions. A European Association of Urology, Section of Uro-Technology (ESUT) project.

OBJECTIVE: To evaluate the variability of subjective tutor performance improvement (Pi) assessment and to compare it with a novel measurement algorithm: the Pi score. MATERIALS AND METHODS: The Pi-score algorithm considers time measurement and number of errors from two different repetitions (first and fifth) of the same training task and compares them to the relative task goals, to produce an objective score. We collected data during eight courses on the four European Association of Urology training in Basic Laparoscopic Urological Skills (E-BLUS) tasks. The same tutor instructed on all courses. Collected data were independently analysed by 14 hands-on training experts for Pi assessment. Their subjective Pi assessments were compared for inter-rater reliability. The average per-participant subjective scores from all 14 proctors were then compared with the objective Pi-score algorithm results. Cohen's κ statistic was used for comparison analysis. RESULTS: A total of 50 participants were enrolled. Concordance found between the 14 proctors' scores was the following: Task 1, κ = 0.42 (moderate); Task 2, κ = 0.27 (fair); Task 3, κ = 0.32 (fair); and Task 4, κ = 0.55 (moderate). Concordance between Pi-score results and proctor average scores per participant was the following: Task 1, κ = 0.85 (almost perfect); Task 2, κ = 0.46 (moderate); Task 3, κ = 0.92 (almost perfect); Task 4 = 0.65 (substantial). CONCLUSION: The present study shows that evaluation of Pi is highly variable, even when formulated by a cohort of experts. Our algorithm successfully provided an objective score that was equal to the average Pi assessment of a cohort of experts, in relation to a small amount of training attempts.

Impact of neoadjuvant chemotherapy on short-term complications and survival following radical cystectomy.

OBJECTIVES: To compare perioperative and short-term postoperative complication rates between patients receiving radical cystectomy (RC) after neoadjuvant chemotherapy (NAC) and patients undergoing RC alone. Secondary objectives were to compare overall survival (OS) and cancer-specific survival (CSS). MATERIALS AND METHODS: Clinico-pathological data of all patients who received RC between 1996 and 2015 were retrospectively collected. Only patients with RC for muscle-invasive bladder cancer were included in the final analysis. Short-term (30-day) postoperative complications were assessed by registering the Clavien-Dindo classification (CDC) and dividing into sub-groups: low-grade (LGC) CDC 1-2 and high-grade (HGC) CDC 3-5. To compare populations with similar age, comorbidities and preoperative creatinine, we used a propensity score-adjusted statistical model. Pre- and perioperative predictors of short-term complications were identified using uni- and multivariable models. Survival was assessed using Kaplan-Meier analysis. RESULTS: A total of 491 patients undergoing RC were included, of whom 102 (20.8%) received NAC. After propensity score covariate adjustment, there was no significant difference in postoperative complications between patients undergoing NAC plus RC and RC alone with an overall complication rate of 69% and 66%, respectively. No significant differences in the 30-day HGC rates (11.76% and 11.83%, respectively) were observed. NAC plus RC patients had worse prognostic factors at baseline; nevertheless, after correction for group differences OS and CSS did not differ from RC only group (5-year OS 61.3% vs. 50.2%, and 5-year CSS 61.8% vs. 57.9% respectively, p > 0.05 for all). CONCLUSION: In appropriately selected patients, exposure to NAC is not associated with increased short-term complications.

Current trends in patient enrollment for robotic-assisted laparoscopic prostatectomy in Belgium.

BACKGROUND: During the last decade, an inverse stage migration has been observed in radical prostatectomy series at tertiary centers. However, it remains unclear whether similar trends can also be observed in solely robotic practices, including nonreferral centers. The aim of this study was to investigate the clinical and pathological trends in robotic-assisted laparoscopic prostatectomy (RALP) enrollment in Belgium over a period of 6 years through an analysis of a prospective registry. METHODS: A prospective, multicenter database was constructed: consecutive patients undergoing RALP in Belgium from 2010 to 2015 were enrolled, and 7366 men were analyzed. Variations in clinical and pathological variables were explored as a function of the enrollment year with proportional odds for categorical variables and with linear regressions for continuous variables. RESULTS: Net increases were observed in the prostate-specific antigen levels, cT stage, and biopsy Gleason scores across the study years (P < .001). The rate of low-risk prostate cancer (PCa) decreased from 36% in 2010 to 21% in 2015, whereas the rate of intermediate-risk PCa rose from 47% to 58%, and the rate of high-risk PCa rose from 17% to 21%. In parallel, the pT2 stage rate decreased from 76% to 64%, and the rate of Gleason 6 (3 + 3) cases was reduced from 45% to 23% (P < .001). Conversely, the pT3a stage rate rose from 16% to 24%, the pT3b stage rate rose from 7% to 11%, and the rate of Gleason 7 (4 + 3) cases rose from 7% to 21% (P < .0001). Finally, more patients underwent node dissection, and positive lymph nodes were increasingly diagnosed (from 3% in 2010 to 7% in 2015). CONCLUSIONS: During the last 6 years of RALP implementation in Belgium, there was a significant increase in the enrollment of intermediate- and high-risk PCa patients. This yielded a significant increase in adverse pathological characteristics. These results suggest a paradigm shift in PCa treatment, with radical robotic surgery increasing for intermediate- and high-risk patients. Cancer 2017;123:4139-4146. © 2017 American Cancer Society.

The value of simulation-based training in the path to laparoscopic urological proficiency.

PURPOSE OF REVIEW: Numerous factors have reduced the training opportunities of surgical residents in the operating room. There is also the question of patient's safety. This gives a need for increased training opportunities outside the operating room. We look if there is an added value in simulation-based training (SBT) in the acquisition of laparoscopic skills. RECENT FINDINGS: Incorporating SBT into the medical students curriculum reduces surgical complication rates in the operating room. SUMMARY: Reduction in opportunities to train surgical skills in the operating room, increased complexity of surgical procedures, and justified concerns for patients' safety require training opportunities outside the operating room. Data proves that skills, acquired in the lab during SBT, are transferable to the operating room. Moreover, incorporating an evidence-based laparoscopic simulation curriculum shortens the clinical learning curve and reduces surgical adverse events.

Training in minimally invasive surgery in urology: European Association of Urology/International Consultation of Urological Diseases consultation.

OBJECTIVES: To describe the progress being made in training for minimally invasive surgery (MIS) in urology. METHODS: A group of experts in the field provided input to agree on recommendations for MIS training. A literature search was carried out to identify studies on MIS training, both in general and specifically for urological procedures. RESULTS: The literature search showed the rapidly developing options for e-learning, box and virtual training, and suggested that box training is a relatively cheap and effective means of improving laparoscopic skills. Development of non-technical skills is an integral part of surgical skills training and should be included in training curricula. The application of modular training in surgical procedures showed more rapid skills acquisition. Training curricula for MIS in urology are being developed in both the USA and Europe. CONCLUSION: Training in MIS has shifted from 'see-one-do-one-teach-one' to a structured learning, from e-learning to skills laboratory and modular training settings.

Construct, content and face validity of the camera handling trainer (CHT): a new E-BLUS training task for 30° laparoscope navigation skills.

PURPOSE: Assessing construct, face and content validity of the camera handling trainer (CHT), a novel low-fidelity training device for 30° laparoscope navigation skills. METHODS: We developed a custom-designed box trainer with clinically based graphic targets. A total of 117 participants, stratified according to their previous experience (novice, competent, expert), took part to a CHT session and subsequently were asked to fill out a survey to assess the impact of the CHT on their 30° laparoscope navigation skills. Sixty of them were also studied for task performance during a 1-h session, with multiple time measurements. RESULTS: All participants, regardless of the previous experience, significantly improved their performance after the CHT session. Regarding construct validity, the mean task performance on the last measurement for novice group was found to be comparable to the mean first attempt of both competent (p = 0.12) and expert (p = 0.24) participants. All participants agreed that "the CHT is a valid training tool" and that "the CHT should be part of the regular dry laboratory training sessions", assessing both face and content validity. Limitations include the need for assessment of predictive validity. CONCLUSIONS: The CHT is a valid training tool for 30° laparoscope navigation and thus should be considered as one of the fundamental exercises during basic laparoscopic hands-on training sessions for urologists.

Hypofractionated palliative radiotherapy for bladder cancer.

PURPOSE: The aim of this study was to evaluate hematuria-free survival as well as acute and late toxicity after hypofractionated palliative radiotherapy for bladder cancer. METHODS AND MATERIALS: Between September 2004 and January 2013, 44 patients with biopsy-proven urothelial carcinoma of the bladder were irradiated according to a palliative schedule to a total dose of 34.5 Gy in six fractions of 5.75 Gy given once a week. RESULTS: After a mean follow-up of 10 months, 91% of patients were still hematuria free, with a mean hematuria-free survival of 13 months. Severe (≥ grade 3) acute and late urinary toxicity was observed in 9 and 19% of patients, respectively. CONCLUSION: This hypofractionated radiotherapy schedule appears to result in acceptable toxicity and manages successful and long-term palliation of hematuria in most patients.

Biodistribution of Evans blue in an orthotopic AY-27 rat bladder urothelial cell carcinoma model: implication for the improved diagnosis of non-muscle-invasive bladder cancer (NMIBC) using dye-guided white-light cystoscopy.

OBJECTIVES: To investigate the possibility of using Evans blue (EB) as a novel diagnostic tool to detect bladder tumours with white-light (WL) cystoscopy, in this preclinical study we examine the biodistribution of EB in the different layers (urothelium, submucosa, muscle) of a normal rat bladder and a rat bladder bearing a malignant urothelium composed of syngeneic AY-27 tumour cells. MATERIALS AND METHODS: EB was instilled into both normal as well as tumour-bearing rat bladders. After instillation, bladders were removed and snap frozen in liquid nitrogen. The distribution of EB in the different layers was quantified using fluorescence microscopy. To gain more insight into the mechanism underlying the selective accumulation of EB in tumour tissue, bladder sections were prepared for ultrastructural investigations by means of transmission electron microscopy (TEM). In addition, we also examined the expression of E-cadherin, claudin-1 and desmoglein-1 by immunohistochemistry to study the integrity of the bladder wall, as these molecules are key constituents of adherens junctions, tight junctions and desmosomes, respectively. RESULTS: In most cases, the accumulation of EB in malignant bladders was substantially higher than in healthy bladders, at least when 1 mm EB instillations were used. In case of a 1 mm EB instillation for 2 h, the EB-associated fluorescence in malignant urothelial tissue was 55-times higher than the fluorescence found in normal urothelium. Ultrastructurally, malignant tissue displayed wider intercellular spaces and a decreased number of cell junction components compared with normal tissue, pointing to defects in the urothelial barrier. There were no differences in the expression of E-cadherin, whereas desmoglein-1 staining was stronger in the membranes of healthy bladder urothelium compared with tumour tissue. Claudin-1 expression was negative in all samples tested. CONCLUSION: EB is selectively taken up by tumour tissue after intravesical instillations in rats bearing bladder tumours. The lower expression of desmoglein-1 in tumour samples, together with the reduced presence of desmosomes seen with TEM, likely imply that desmosomes play an important role in the ultrastructural differences between healthy rat urothelium and tumour tissue, and secondary to that, to the differential uptake of EB in both tissues. We consider that our findings could be useful for future clinical developments in the field of diagnostics for bladder cancer.

Current status and effectiveness of mentorship programmes in urology: a systematic review.

The objectives of this review were to identify and evaluate the efficacy of mentorship programmes for minimally invasive procedures in urology and give recommendations on how to improve mentorship. A systematic literature search of the PubMed/Medline databases was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In all, 21 articles were included in the review and divided into four categories: fellowships, mini-fellowships, mentored skills courses and novel mentorship programmes. Various structures of mentorship programme were identified and in general, mentorship programmes were found to be feasible, having content validity and educational impact. Perioperative data showed equally good outcomes when comparing trainees and specialists. Mentorship programmes are effective and represent one of the best current methods of training in urology. However, participation in such programmes is not widespread. The structure of mentorship programmes is highly variable, with no clearly defined 'best approach' for postgraduate training. This review offers recommendations as to how this 'best approach' can be established.

Development of a standardised training curriculum for robotic surgery: a consensus statement from an international multidisciplinary group of experts.

OBJECTIVES: To explore the views of experts about the development and validation of a robotic surgery training curriculum, and how this should be implemented. MATERIALS AND METHODS: An international expert panel was invited to a structured session for discussion. The study was of a mixed design, including qualitative and quantitative components based on focus group interviews during the European Association of Urology (EAU) Robotic Urology Section (ERUS) (2012), EAU (2013) and ERUS (2013) meetings. After introduction to the aims, principles and current status of the curriculum development, group responses were elicited. After content analysis of recorded interviews generated themes were discussed at the second meeting, where consensus was achieved on each theme. This discussion also underwent content analysis, and was used to draft a curriculum proposal. At the third meeting, a quantitative questionnaire about this curriculum was disseminated to attendees to assess the level of agreement with the key points. RESULTS: In all, 150 min (19 pages) of the focus group discussion was transcribed (21 316 words). Themes were agreed by two raters (median agreement κ 0.89) and they included: need for a training curriculum (inter-rater agreement κ 0.85); identification of learning needs (κ 0.83); development of the curriculum contents (κ 0.81); an overview of available curricula (κ 0.79); settings for robotic surgery training ((κ 0.89); assessment and training of trainers (κ 0.92); requirements for certification and patient safety (κ 0.83); and need for a universally standardised curriculum (κ 0.78). A training curriculum was proposed based on the above discussions. CONCLUSION: This group proposes a multi-step curriculum for robotic training. Studies are in process to validate the effectiveness of the curriculum and to assess transfer of skills to the operating room.

Clinical outcome after radical excision of moderate-severe endometriosis with or without bowel resection and reanastomosis: a prospective cohort study.

OBJECTIVE: To assess the clinical outcome of women requiring laparoscopic excision of moderate-severe endometriosis in women with and without bowel resection and reanastomosis. METHODS: Two hundred three patients with laparoscopically excised moderate (n = 67) or severe (n = 136) endometriosis (rAFS: revised endometriosis classification of the American Fertility Society) were prospectively followed during a median of 20 months (1-45 months) using a CONSORT-inspired checklist. Patients completed the EHP30 Quality-of-Life Questionnaire and visual analogue scales (VAS) for dysmenorrhea, chronic pelvic pain, and deep dyspareunia and answered questions about postoperative complications, reinterventions/recurrences, and fertility outcome 1 month before and 6, 12, 18, and 24 months after surgery. Clinical outcome was compared between women with deeply infiltrative endometriosis undergoing CO2 laser ablative surgery with bowel resection (study group, 76/203; 37%) and without bowel resection (control group, 127/203; 63%). RESULTS: Both groups were similar with respect to population characteristics and clinical outcome, except for mean rAFS score [higher in study group (73 ± 31) than in control group (48 ± 26)] and minor complication rate [higher in study group (11%) than in control group (1%)]. In both groups, mean VAS and EHP30 scores improved significantly and remained stable for 24 months after surgery, with a pregnancy rate of 51%. Within 1, 2, and 3 years follow-up, the cumulative reintervention rate was 1%, 7%, and 10%, respectively, and the cumulative endometriosis recurrence rate was 1%, 6%, and 8%, respectively. CONCLUSIONS: Clinical outcome after CO2 laser laparoscopic excision of moderate-severe endometriosis was comparable in women with or without bowel resection and reanastomosis, except for a higher minor complication rate occurring in women with bowel resection and reanastomosis (NCT00463398).

Prototol for the Prospective Sample Collection for Cancer of Bladder (ProCaB) Trial by the Cancer of the Bladder Leuven (CaBLe) Consortium.

Non-muscle-invasive bladder cancer (NMIBC) is a heterogeneous disease categorized as low, intermediate, high, or very high risk, for which recurrence and progression rates and thus management strategies differ. Current molecular subclassification of bladder cancer (BC) is mainly based on data for muscle-invasive disease, with very few data for NMIBC. A more accurate classification system is needed for better stratification of NMIBC using multiomics and immunohistopathological molecular data alongside clinical data collected in a prospective cohort. ProCaB (Prospective Sample Collection for Cancer of Bladder) is a single-center non-interventional, prospective study recruiting all eligible patients diagnosed with BC in a tertiary center in the Flanders region of Belgium. Clinical data have been collected in a prospective registry since August 2013. Biosamples (blood, urine, and BC tissue) are collected from each patient at diagnosis and are stored at -80°C at BioBank UZ Leuven after appropriate processing according to the protocol. Multiomics (genomics, epigenetics, transcriptomics, proteomics, lipidomics, metabolomics) and immunohistopathology analyses will be performed on appropriate samples. The target is to enroll 300 patients over a 5-yr period, and all patients will be followed for 5 yr. The objective is to create a biobank of samples from patients diagnosed with BC for use in multiomics and immunohistopathological analyses. Results from these analyses, together with long-term clinical data, can be used for comprehensive multilayered molecular characterization of disease recurrence and progression in intermediate- and (very) high-risk NMIBC, identification of multibiomarker panels for better stratification, and identification of a patient subgroup that does not respond to bacillus Calmette-Guérin treatment. This trial is registered on ClinicalTrials.gov as NCT04167332.

Functional Outcomes and Quality of Life in High-risk Prostate Cancer Patients Treated by Robot-assisted Radical Prostatectomy with or Without Adjuvant Treatments.

BACKGROUND: Robot-assisted laparoscopic prostatectomy (RALP) is used frequently to treat prostate cancer; yet, prospective data on the quality of life and functional outcomes are lacking. OBJECTIVE: To assess the quality of life and functional outcomes after radical prostatectomy in different risk groups with or without adjuvant treatments. DESIGN, SETTING, AND PARTICIPANTS: The Be-RALP database is a prospective multicentre database that covers 9235 RALP cases from 2009 until 2016. Of these 9235 patients, 2336 high-risk prostate cancer patients were matched with low/intermediate-risk prostate cancer patients. INTERVENTION: Patients were treated with RALP only or followed by radiotherapy and/or hormone treatment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We used a mixed-model analysis to longitudinally analyse quality of life, urinary function, and erectile function between risk groups with or without additional treatments. RESULTS AND LIMITATIONS: Risk group was not significant in predicting quality of life, erectile function, or urinary function after RALP. Postoperative treatment (hormone and/or radiotherapy treatment) was significant in predicting International Index of Erectile Function (IIEF-5), sexual activity, and sexual functioning. CONCLUSIONS: Risk group was not linked with clinically relevant declines in functional outcomes after RALP. The observed functional outcomes and quality of life are in favour of considering RALP for high-risk prostate cancer. Postoperative treatment resulted in lower erectile function measures without clinically relevant changes in quality of life and urinary functions. Hormone therapy seems to have the most prominent negative effects on these outcomes. PATIENT SUMMARY: This study investigated the quality of life, and urinary and erectile function in patients with aggressive and less aggressive prostate cancer after surgery only or in combination with hormones or radiation. We found that quality of life recovers completely, while erectile and urinary function recovers only partially after surgery. Aggressiveness of the disease had a minimal effect on the outcomes; yet, postoperative treatments lowered erectile function further.
