Objective: To provide the first clinical validation of the European Association of Urology Robotic Urology Section (ERUS) curriculum for training in robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC).

Patients And Methods: The ERUS proposed a structured curriculum, divided into 11 steps, to train novice surgeons and help overcome the steep learning curve associated with iRARC. In this study, one trainee completed the curriculum under the mentorship of an expert.

Do perioperative blood transfusions impact oncological outcomes of robot-assisted radical cystectomy with intracorporeal urinary diversion? Results from a large multi-institutional registry.

Background: Blood transfusions (BT) have been associated with adverse oncologic outcomes in multiple malignancies including open radical cystectomy (ORC) for urothelial carcinoma of the bladder (UCB). Robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) delivers similar oncologic outcomes compared to ORC, yet with lower blood loss and reduced transfusions. However, the impact of BT after robotic cystectomy is still unknown.

Multiple trials are currently studying the additional effect of immunotherapy on neoadjuvant chemotherapy (NAC) in nonmetastatic muscle-invasive bladder cancer. We performed a systematic review of the literature that summarizes all ongoing trials, with their results when available. From an initial 269 trials identified, 17 were included.

Cost-analysis of robot-assisted radical cystectomy in Europe: A cross-country comparison.

Background: Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is surging worldwide. Aim of the study was to perform a multicentric cost-analysis of RARC by comparing the gross cost of the intervention across hospitals in four different European countries.

Methods: Patients who underwent RARC + ICUD were recruited from eleven European centers in four European countries (Belgium, France, Netherlands, and UK) between 2015 and 2020.

Clinical experience with F-JK-PSMA-7 when using a digital PET/CT.

Background: Digital PET/CT systems make use of a new technology with higher sensitivity and other better technological features than the analog ones. They require adaptation of the trade-off between performance, tracer dose and acquisition time. The aim of the study was to explore the performance of F-JK-PSMA-7 imaging when performed on a digital PET/CT with an adapted protocol, in a population of patients with prostate cancer patients (PCa).

Defining the Morbidity of Robot-Assisted Radical Cystectomy with Intracorporeal Urinary Diversion: Adoption of the Comprehensive Complication Index.

The Clavien-Dindo Classification (CDC) only reports the postoperative complication of highest grade. It is thus of limited value for radical cystectomy, after which patients usually experience multiple complications. The Comprehensive Complication Index (CCI) is a novel scoring system, which incorporates all postoperative events in one single value.

Continuing acetylsalicylic acid during Robotic-Assisted Radical Cystectomy with intracorporeal urinary diversion does not increase hemorrhagic complications: results from a large multicentric cohort.

Objectives: To evaluate whether continuing the antiplatelet drug acetylsalicylic acid≤100mg (ASA) during Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) increases the risk of peri-and postoperative hemorrhagic complications and overall morbidity. Indeed, guidelines recommend interrupting antiplatelet therapy before radical cystectomy; however, RARC with ICUD is associated to reduced estimated blood loss and blood transfusions compared to its open counterpart.

Methods: Data from a multicentric European database were analyzed.

External Validation of a Multiparametric Magnetic Resonance Imaging-based Nomogram for the Prediction of Extracapsular Extension and Seminal Vesicle Invasion in Prostate Cancer Patients Undergoing Radical Prostatectomy.

The nomogram reported by Gandaglia et al (The key combined value of multiparametric magnetic resonance imaging, and magnetic resonance imaging-targeted and concomitant systematic biopsies for the prediction of adverse pathological features in prostate cancer patients undergoing radical prostatectomy. Eur Urol 2020;77:733-41) predicting extracapsular extension (ECE) or seminal vesicle invasion (SVI) has been developed using multiparametric magnetic resonance imaging (MRI) parameters and MRI-targeted biopsy. We aimed to validate this nomogram externally by analyzing 566 patients harboring prostate cancer diagnosed on MRI-targeted biopsy followed by radical prostatectomy.

Timing and delay of radical prostatectomy do not lead to adverse oncologic outcomes: results from a large European cohort at the times of COVID-19 pandemic.

Purpose: The current COVID-19 pandemic is transforming our urologic practice and most urologic societies recommend to defer any surgical treatment for prostate cancer (PCa) patients. It is unclear whether a delay between diagnosis and surgical management (i.e.

Concordance Between Biopsy and Radical Prostatectomy Gleason Scores: Evaluation of Determinants in a Large-Scale Study of Patients Undergoing RARP in Belgium.

To determine whether Gleason scores were concordant between prostate biopsies (bGS) and the definitive resection specimen (pGS) excised with robot-assisted radical prostatectomy (RARP); to identify clinical and pathological factors that might predict upgrading; and to evaluate how upgrading affected outcome. Between 2009 and 2016, 25 Belgian centers participated in collecting prospective data for patients that underwent RARP. We analyzed the concordance rate between the bGS and the pGS in 8021 patients with kappa statistics, and we compared concordance rates from different centers.

Development and external validation of a nomogram to predict lymph node invasion after robot assisted radical prostatectomy.

Background: Prediction of lymph node invasion (LNI) after radical prostatectomy has been rarely assessed in robotically assisted laparoscopic radical prostatectomy (RALP) series. We aimed to develop and externally validate a pretreatment nomogram for the prediction of LNI following RALP in patients with high- and intermediate-risk prostate cancer.

Methods: 1654 RALP patients were prospectively collected between 2009 and 2016 from academic and community hospitals.

The impact of neutrophil-to-lymphocyte, platelet-to-lymphocyte and haemoglobin-to-platelet ratio on localised renal cell carcinoma oncologic outcomes.

Introduction: The neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) are established markers of systemic inflammation. Moreover, anemia is a known adverse prognostic factor and reduced haemoglobin to platelet ratio (HPR) seems associate to poor outcomes in urothelial cancer. Aim of the current study was to explore the prognostic value of NLR, HPR and PLR in patients harboring localized RCC.

Validated Prospective Assessment of Quality of Life After Robot-Assisted Laparoscopic Prostatectomy: Beyond Continence and Erections.

Continence and erectile function represent major concerns after robot-assisted laparoscopic prostatectomy (RALP), although the analysis of only these results may underestimate the impact of surgery on quality of life (QoL). The aim of the study is to prospectively analyze QoL after RALP according to the validated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire prostate cancer-specific module (EORTC-QLQ-PR25) and C30 and explore risk factors for the deterioration of QoL after surgery. A total of 584 patients undergoing RALP were prospectively enrolled.

Development and External Validation of Nomograms To Predict Adverse Pathological Characteristics After Robotic Prostatectomy: Results of a Prospective, Multi-institutional, Nationwide series.

Background: The possibility of predicting pathologic features before surgery can support clinicians in selecting the best treatment strategy for their patients. We sought to develop and externally validate pretreatment nomograms for the prediction of pathological features from a prospective multicentre series of robotic-assisted laparoscopic prostatectomy (RALP) procedures.

Design, Setting, And Participants: Between 2009 and 2016, data from 6823 patients undergoing RALP in 25 academic and community hospitals were prospectively collected by the Belgian Cancer Registry.

The impact of postoperative inflammatory biomarkers on oncologic outcomes of bladder cancer.

Introduction: The clinical impact of inflammatory biomarkers has been evaluated in urothelial bladder cancer. However, data are limited to preoperative values and there is paucity of evidence of the role of postoperative measurement of those biomarkers. The aim of the current study was to determine the association of inflammatory biomarkers as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), hemoglobin to platelet ratio (HPR) and C-reactive protein (CRP), before and after radical cystectomy, with recurrence and survival of bladder cancer.

Current Management of pT3b Prostate Cancer After Robot-assisted Laparoscopic Prostatectomy.

Background: Robot-assisted radical prostatectomy (RALP) in high-risk and locally advanced prostate cancer (PCa) is gaining increasing traction. The optimal use of additional treatments for PCa with seminal vesicle invasion (pT3b) after RALP remains ill explored.

Objective: To evaluate the management of pT3b PCa after RALP in current clinical practice.

Exploring positive surgical margins after minimally invasive radical prostatectomy: Does body habitus really make a difference ?

Background: Positive surgical margins (PSMs) at radical prostatectomy (RP) are generally recognized as a surrogate of poor or difficult dissection of the prostatic gland. In open RP cohorts, obesity seems to be associated to an increased risk of PSMs, probably due to the technical challenge that obese men pose to surgical access. Minimally invasive RP has been claimed to possibly reduce PSM rate.

Practical impact of a decision support for goal-directed fluid therapy on protocol adherence: a clinical implementation study in patients undergoing major abdominal surgery.

The purpose of this study was to assess the effects of using a real time clinical decision-support system, "Assisted Fluid Management" (AFM), to guide goal-directed fluid therapy (GDFT) during major abdominal surgery. We compared a group of patients managed using the AFM system with a historical cohort of patients (control group) who had been managed using a manual GDFT strategy. Adherence to the protocol was defined as the relative intraoperative time spent with a stroke volume variation (SVV) < 13%.
