BACKGROUND Minimal access surgery (MAS) is well-established in urological surgery. However, MAS is technically demanding and associated with a prolonged learning curve. Robot-assisted laparoscopy has made progress in overcoming these challenges. OBJECTIVE The aim of this study was to evaluate the feasibility of a new robot-assisted surgical system (the Versius Surgical System; CMR Surgical, Cambridge, UK) for renal and prostate procedures in a preclinical setting, at the IDEAL-D phase 0. DESIGN, SETTING, AND PARTICIPANTS Cadaveric sessions were conducted to evaluate the ability of the system to complete all surgical steps required for a radical nephrectomy, prostatectomy, and pelvic lymph node dissection. A live animal (porcine) model was also used to assess the surgical device in performing radical nephrectomy safely and effectively. Procedures were performed by experienced renal and prostate surgeons, supported by a full operating room team. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Surgical access and of the Versius Surgical System for renal and prostate procedures. The safety and effectiveness of the system have been demonstrated and warrant progressive assessment in a clinical setting utilising the IDEAL-D framework. PATIENT SUMMARY In this report, we looked at the usability of a new robot-assisted surgical device for renal and prostate surgery by testing the system in cadavers and pigs. We found that a number of different surgeons and operating team personnel were able to use the system to successfully complete the procedures under evaluation. We conclude that the system is ready to be tested in live human studies. BACKGROUND Synchronous metastasis (SM) rates in T1 renal cell carcinoma (RCC) patients relied on historical cohorts and may not take into account the favorable stage migration toward lower tumor size (TS) that occurred in more recent years. OBJECTIVE To investigate SM rates in T1 RCC patients according to histological subtype (HS), tumor grade (TG), and TS. INTERVENTION Partial nephrectomy, radical nephrectomy, focal ablation, and non-interventional management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Within the Surveillance, Epidemiology, and End Results database (2004-2015), 60 640 stage T1 patients were identified. SM rates were tabulated and tested in multivariable logistic regression models. RESULTS AND LIMITATIONS According to HS, average SM rates were 0%, 0.5%, 1.1%, 1.4%, 3.7%, 21.5%, and 36.2% for multilocular cystic, chromophobe, papillary, clear cell TG 1-2, clear cell TG 3-4, collecting duct, and sarcomatoid RCC, respectively. In a multivariate logistic regression model, age, TS, HS, and TG were independent predictors of SM. Bone only was the commonest metastatic site (41.0%), followed by lung only (24.5%), liver only (3.6%), and brain only (3.8%). Of all SM patients, 72.8% harbored a single metastatic site. The major limitations of this study are lack of recurrence and metastatic progression data. CONCLUSIONS Within T1 RCC, it was possible to identify five metastatic risk categories according to SM rates (1) multilocular cystic RCC (0%), (2) chromophobe RCC (0-2.0%), (3) clear cell TG 1-2 and papillary RCC, (4) clear cell TG 3-4 RCC (1.2-8.9%), and (5) sarcomatoid and collecting duct RCC (7.0-49.1%). The most frequent metastatic location is bone only, followed by lung only, and virtually all SMs are solitary. PATIENT SUMMARY Metastatic rate varies in T1 stage renal cell carcinoma patients according to tumor size, histology, and tumor grade. V.OBJECTIVE The Risk Analysis Index (RAI) has been used to evaluate preoperative frailty, which is associated with poor short- and long-term outcomes. We assessed this tool’s ability to predict postoperative outcomes after endovascular aortic aneurysm repair. METHODS Institutional Review Board approval was obtained for this retrospective study. All patients who underwent elective endovascular aneurysm repair at a single Veterans Affairs Medical Center from December 2010 to March 2016 were included. Patients’ characteristics and clinical data were retrospectively collected and analyzed. The RAI score was calculated from preoperative data, and a standard cutoff value (RAI ≥30) was used to determine frailty. Outcomes including postoperative complications, delayed discharge, and survival were compared between frail and nonfrail groups. Multivariate analysis was performed to evaluate preoperative factors associated with these outcomes. TPEN RESULTS There were 134 patients who met inclusion criteria. There were 44 frail patients (RAI ≥30) and 90 nonfrail patients (RAI  less then 30). Frail patients had a longer hospital stay (3.9 ± 4.0 days vs 2.3 ± 1.6 days; P = .02), increased operative time (155 ± 30 minutes vs 138 ± 30 minutes; P = .002), and increased postoperative complications (43% vs 21%; P = .02) compared with nonfrail patients. Kaplan-Meier average survival for frail patients and nonfrail patients was 60 ± 4 months and 84 ± 3 months (P  less then .001), respectively. In multivariate analyses, frailty was associated with worse overall survival (hazard ratio, 3.7; 95% confidence interval [CI], 1.8-7.3) and higher odds of complications (odds ratio, 1.1; 95% CI, 1.0-1.14) and delayed discharge (odds ratio, 1.1; 95% CI, 1.05-1.2). CONCLUSIONS Preoperative frailty as evaluated by the RAI is associated with worse short-term postoperative outcomes and long-term mortality. The RAI can be used to inform risk-benefit discussions with patients and their families. Published by Elsevier Inc.OBJECTIVE The role of carotid endarterectomy (CEA) continues to be debated in the age of optimal medical therapy, particularly for patients with limited life expectancy. The Risk Analysis Index (RAI) measures frailty, a syndrome of decreased physiologic reserve, which increases vulnerability to adverse outcomes. The RAI better predicts surgical complications, nonhome discharge, and death than age or comorbidities alone. We sought to measure the association of frailty, as measured by the RAI, with postoperative in-hospital stroke, long-term stroke, and long-term survival after CEA. We also sought to determine how postoperative stroke interacts with frailty to alter survival trajectory after CEA. METHODS We queried the Vascular Quality Initiative CEA procedure and long-term data sets (2003-2017) for elective CEAs with complete RAI case information. For all analyses, the cohort was divided into asymptomatic and symptomatic carotid stenosis. Scoring was defined as not frail (RAI  less then 30), frail (RAI 30-34), and very frail (RAI ≥35).
