Abstract Introduction Multicenter retrospective analysis of robotic partial nephrectomy for completely endophytic renal tumors (i.e. 3 points for the ‘E’ domain of the R.E.N.A.L. nephrometry score) was performed. Materials and methods Patients’ demographics, tumor characteristics, perioperative, functional, pathological and oncological data were analyzed and compared with those of patients with exophytic and mesophytic masses (i.e. 1 and 2 points for the ‘E’ domain, respectively). Multivariable logistic regression analysis was used to assess variables for trifecta achievement (negative margin, no postoperative complications, and 90% estimated glomerular filtration rate [eGFR] recovery). Results Overall, 147 patients were included in the study group. Patients with a completely endophytic mass had bigger tumors (mean 4.2 vs. 4.1 vs. 3.2 cm; p Conclusions Our findings confirm that RAPN in case of completely endophytic renal masses can be performed with acceptable outcomes in centers with significant robotic expertise.
Abstract Background Despite technical improvements introduced with robotic surgery, management of complex tumours (PADUA score ≥10) is still a matter of debate within the field of transperitoneal robot-assisted partial nephrectomy (RAPN). Objective To evaluate the accuracy of our three-dimensional (3D) static and elastic augmented reality (AR) systems based on hyperaccuracy models (HA3D) in identifying tumours and intrarenal structures during transperitoneal RAPN (AR-RAPN), compared with standar...
BACKGROUND: To develop a clinical nomogram aimed to predict the achievement of trifecta in patients treated with open, laparoscopic and robotic partial nephrectomy (PN) for localized renal masses ( < cT2). METHODS: We retrospectively evaluated 482 consecutive patients who underwent PN with open (OPN: 243), laparoscopic (LPN: 156) and robotic (RAPN: 83) approach for T1 renal mass at single tertiary center. Trifecta was defined as follows: warm ischemia time (WIT) <20 min and no positive surgical ...
Abstract Context The use of near-infrared fluorescence (NIRF) imaging was described to facilitate selective clamping during robot-assisted partial nephrectomy (RAPN). Objective To perform a systematic review and cumulative analysis of available studies comparing the outcomes of RAPN with or without use of this technology (NIRF). Evidence acquisition A systematic review of the literature was performed to identify relevant studies up to December 2018 through PubMed and EMBASE databases. A meta-ana...
INTRODUCTION: Robotic surgery for the management of localized renal cell carcinoma (RCC) has gained increasing popularity during the last decade. An endophytic renal tumour represents a surgical technical challenge in terms of identification and resection related to the lack of external visual cues on the kidney surface. MATERIALS AND METHODS: There is little evidence of functional outcomes of robotic surgery on treating endophytic masses. For this reason, we wanted to review the contemporary li...
Abstract Background Complexity of robot-assisted partial nephrectomy (RAPN) mostly depends on tumor size and location. Totally endophytic renal masses represent a surgical challenge in terms of both intraoperative identification and anatomical dissection. Objective To detail a novel technique for marking preoperatively endophytic renal tumors with transarterial superselective intrarenal mass delivery of indocyanine green (ICG)-lipiodol mixture, in order to enhance surgical margins control during...
Abstract Background No validated training program for robot-assisted partial nephrectomy (RAPN) exists. Objective To define the structure and provide a pilot clinical validation of a curriculum for robot-assisted partial nephrectomy (RAPN). Design, setting, and participants A modified Delphi consensus methodology involving 27 experts defined curriculum structure. One trainee completed the curriculum under the mentorship of an expert. A total of 40 patients treated with curriculum RAPN (cRAPN) we...
INTRODUCTION: Robot-assisted partial nephrectomy (RAPN) is increasingly used for the surgical management of renal masses. Aim of this study was to analyze the available literature regarding the outcomes of RAPN compared to those of open partial nephrectomy (OPN). EVIDENCE ACQUISITION: A literature search was performed up to October 2018 using PubMed, MEDLINE and Embase. Article selection followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) principles and Popul...

Investigators submitting clinical research to European Urology are encouraged to follow guidelines for the reporting of statistics. Adoption of the guidelines will not only increase the quality of published papers, but also improve statistical knowledge in urology in general.
CONTEXT As robot-assisted surgery is increasingly used in surgical care, the engineering research effort towards surgical automation has also increased significantly. Automation promises to enhance surgical outcomes, offload mundane or repetitive tasks, and improve workflow. However, we must ask an important question: should autonomous surgery be our long-term goal? OBJECTIVE To provide an overview of the engineering requirements for automating control systems, summarize technical challenges in ...
PURPOSE To assess the outcomes of retroperitoneal robot-assisted partial nephrectomy (r-RAPN) in a large cohort of patients with postero-lateral renal masses comparing to those of transperitoneal RAPN (t-RAPN). METHODS Patients with posterior (R.E.N.A.L. score grading P) or lateral (grading X) renal mass who underwent RAPN in six high-volume US and European centers were identified and stratified into two groups according to surgical approach: r-RAPN ("study group") and t-RAPN ("control group"). ...
BACKGROUND Patient with "very small" (<2 cm) renal mass can be offered active surveillance, thermal ablation, or partial nephrectomy. The management strategy will consider patient preferences and prioritize potential harms associated with each of these options. To date, outcomes of robot-assisted partial nephrectomy (RAPN) in patients with "very small" renal masses have not been reported. OBJECTIVE To assess the outcomes of RAPN among patients with "very small" renal masses. DESIGN, SETTING, AND...
