INTRODUCTION: We sought to assess the impact of surgical wait time (SWT) to robot-assisted radical prostatectomy (RARP) on final pathological outcome. METHODS: A retrospective review of RARP patient records operated between 2006 and 2015 was conducted. SWT was defined as period from prostate biopsy to surgery. Primary outcome was the impact on postoperative Cancer of the Prostate Risk Assessment (CAPRA-S) score. Patients were stratified according to D'Amico risk categories...

PURPOSE: The updated Winter nomogram is the only nomogram predicting lymph node invasion (LNI) in prostate cancer (PCa) patients based on sentinel node (SN) dissection (sLND). The aim of the study was to externally validate the Winter nomogram and examine its performance in patients undergoing extended pelvic lymph node dissection (ePLND), ePLND combined with SN biopsy (SNB) and sLND only. The results were compared with the Memorial Sloan Kettering Cancer Center (MSKCC) and updated Briganti nomograms...

PURPOSE: We explore and validate objective surgeon performance metrics using a novel recorder ("dVLogger") to directly capture surgeon manipulations on the da Vinci robot. We present the initial construct and concurrent validation study of objective metrics during pre-selected steps of robot-assisted radical prostatectomy (RARP). METHODS: Kinematic and events data were recorded for expert (≥100 cases) and novice (<100 cases) surgeons performing bladder mobilization (BM), seminal-vesicle dissection (SVD), anterior vesicourethral anastomosis (AA) and right pelvic lymphadenectomy (RLD)...

BACKGROUND: The literature is lacking randomised controlled trials comparing robot-assisted (RARP) and laparoscopic (LRP) radical prostatectomy, especially for follow-up >1 yr. OBJECTIVE: To report 5-yr outcomes for our previously published prospective randomised study comparing RARP and LRP. DESIGN, SETTING, AND PARTICIPANTS: From January 2010 to January 2011, 120 patients with organ-confined prostate cancer were enrolled and randomly assigned to RARP or LRP...

BACKGROUND: Robot-assisted radical prostatectomy (RARP) for prostate cancer (PCa) treatment has been widely adopted with limited evidence for long-term (>5 yr) oncologic efficacy. OBJECTIVE: To evaluate long-term oncologic outcomes following RARP. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of 885 patients who underwent RARP as monotherapy for PCa between 2002 and 2006 in a single European centre and followed up until 2016...

Robot-assisted radical prostatectomy (RARP) has enabled steady and stable surgical procedures due to both meticulous maneuvers and magnified, clear, 3-dimensional vision. Therefore, better surgical outcomes have been expected with RARP than with other surgical modalities. However, even in the RARP era, post-prostatectomy incontinence has a relatively high incidence as a bothersome complication. To overcome post-prostatectomy incontinence, it goes without saying that meticulous surgical procedures and creative surgical procedures, i...

The benefit of adding sentinel node biopsy (SNB) to extended pelvic lymph node dissection (ePLND), remains controversial. Aim of our study was to evaluate biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) and ePLND in prostate cancer (PCa) patients, stratified by the application of SNB. The results were compared with the predictions of the updated Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Methods: Between January 2006 and November 2016, 920 patients underwent RARP with ePLND combined with or without SNB (184 and 736 patients, respectively)...

INTRODUCTION AND OBJECTIVE: With the peritoneum acting as a natural surface for lymphatic reabsorption, transperitoneal robot-assisted radical prostatectomy (tRARP) is thought to be associated with a lower incidence of symptomatic lymphocele (SL) compared to its extraperitoneal counterpart (eRARP) when bilateral pelvic lymph node dissection (BPLND) is performed. Herein, we aim to determine if there is a difference in SL formation and characteristics between the two approaches. METHODS: We reviewed the records of patients who underwent eRARP or tRARP and BPLND at a tertiary care academic center from July 1, 2003 to May 31, 2016...

OBJECTIVE: To study the combination of thermal MRI imaging and novel hypothermic cooling, via an Endorectal Cooling Balloon (ECB) to assess the effective dispersion and temperature drop in pelvic tissue to potentially reduce inflammatory cascade in surgical applications. METHODS: Three male subjects, prior to undergoing robot-assisted radical prostatectomy (RARP), were cooled via an ECB, rendered MRI compatible by for patient safety Prior to ECB hypothermia. MRI studies were performed using a 3T scanner and included T2w anatomical scan for the pelvic structures, followed by a temperature mapping scan...

PURPOSE: To test the impact of surgeon experience on urinary continence (UC) recovery after robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: The study included 1477 consecutive patients treated with RARP by four surgeons between 2006 and 2014. UC recovery was defined as being completely dry over a 24-hour period at follow-up. Surgeon experience was coded as the total number of RARP performed by the surgeon before the patient's operation. Multivariable analysis tested the association between surgeon experience and UC recovery...

PURPOSE: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. MATERIALS AND METHODS: We prospectively collected data from consecutive patients that underwent RARP...

To determine causative factors for de novo inguinal hernia (IH), after robot-assisted radical prostatectomy (RARP). This was a retrospective, single-center study, which included patients undergoing RARP for prostate cancer at our institution, from February 2012 to January 2015. Cox proportional hazards models were used to determine the relationships between de novo IH and various factors. A total of 284 patients were included in the analysis. Forty-two (14.7%) patients developed IH at a median period of 8 months after RARP...

PURPOSE OF REVIEW: A variety of different surgical techniques are thought to impact on urinary continence (UC) recovery in patients undergoing robot assisted radical prostatectomy (RARP) for prostate cancer. Herein, we review current evidence and propose a composite evidence-based technique to optimize UC recovery after RARP. RECENT FINDINGS: A literature search on studies reporting on surgical techniques to improve early continence recovery post robotic prostatectomy was conducted on PubMed and EMBASE...

OBJECTIVE: Our objective was to investigate predictors of early continence outcome after robot-assisted radical prostatectomy (RARP). METHODS: Clinical records were prospectively collected in 272 patients who underwent RARP. Clinical parameters, continence rates, and time to achieve continence were investigated and analyzed. Recovery of continence was defined as achieving complete continence (pad-free). RESULTS: In the univariate analysis, young age (≤67 years) and low pT stage (≤pT2) were significantly associated with continence achieved within 2 weeks after RARP (P = 0...

PURPOSE: The completion of the vescico-urethral anastomosis (VUA) represents the most critical step of laparoscopic radical prostatectomy (LRP), and it can often discourage the use of minimally invasive surgery in less experienced laparoscopic surgeons. The aim of this paper is to evaluate the usefulness of a new robotic needle driver named Dextérité in performing the VUA after LRP. MATERIALS AND METHODS: This prospective randomized clinical study enrolled 40 consecutive patients eligible for LRP, which were randomized into four groups: group A, patients undergoing LRP done by an expert surgeon; group B, patients undergoing robotic-assisted radical prostatectomy (RARP) performed by the same expert surgeon; group C, patients undergoing LRP performed by a young surgeon at the beginning of the learning curve; group D, patients undergoing LRP performed by another young surgeon at the beginning of the learning curve with the aid of Dextérité needle driver for completion of the VUA...
