Learning From Those who Learned: A Survey of Fellowship Trained HoLEP Surgeons and Their Current Practice Patterns.

OBJECTIVE: To gain insight from the experience of learning Holmium laser enucleation of the prostate (HoLEP), teaching HoLEP, and the current HoLEP practice patterns of fellowship-trained endourologists. METHODS: Surveys were electronically distributed to United States (U.S.) practicing urologists who completed American Endourology fellowships (that included HoLEP) within the past 6 years. Questions focused on HoLEP training and current practice patterns. RESULTS: As of September 2019, 12% (6/49) of U.S. endourology fellowships reported including HoLEP as a component of training. With a 73% response rate (16 of 22), 81% participated in over 20 cases during training, while 50% participated in over 50. A total of 25% independently completed over 50 cases from start to finish. At training completion, most (80%) felt comfortable/somewhat comfortable completing an entire HoLEP independently and managing post-op complications. Seventy-five percent practice HoLEP currently, and 25% teach to trainees. When asked "What is most challenging about HoLEP in current practice?" common responses were: efficiency/profitability concerns, poor reimbursement, educating OR/hospital staff, establishing case volume, minimizing sphincter trauma, and large glands (>200gm). CONCLUSION: With diverse exposure in fellowship, most incorporate HoLEP into their practice after training. Aspects of the procedure remain challenging after several years of experience. Profitability/reimbursement concerns should be further explored to increase HoLEP adoption.

Objective assessment of intraoperative skills for robot-assisted radical prostatectomy (RARP): results from the ERUS Scientific and Educational Working Groups Metrics Initiative.

OBJECTIVE: To develop and seek consensus from procedure experts on the metrics that best characterise a reference robot-assisted radical prostatectomy (RARP) and determine if the metrics distinguished between the objectively assessed RARP performance of experienced and novice urologists, as identifying objective performance metrics for surgical training in robotic surgery is imperative for patient safety. MATERIALS AND METHODS: In Study 1, the metrics, i.e. 12 phases of the procedure, 81 steps, 245 errors and 110 critical errors for a reference RARP were developed and then presented to an international Delphi panel of 19 experienced urologists. In Study 2, 12 very experienced surgeons (VES) who had performed >500 RARPs and 12 novice urology surgeons performed a RARP, which was video recorded and assessed by two experienced urologists blinded as to subject and group. Percentage agreement between experienced urologists for the Delphi meeting and Mann-Whitney U- and Kruskal-Wallis tests were used for construct validation of the newly identified RARP metrics. RESULTS: At the Delphi panel, consensus was reached on the appropriateness of the metrics for a reference RARP. In Study 2, the results showed that the VES performed ~4% more procedure steps and made 72% fewer procedure errors than the novices (P = 0.027). Phases VIIa and VIIb (i.e. neurovascular bundle dissection) best discriminated between the VES and novices. LIMITATIONS: VES whose performance was in the bottom half of their group demonstrated considerable error variability and made five-times as many errors as the other half of the group (P = 0.006). CONCLUSIONS: The international Delphi panel reached high-level consensus on the RARP metrics that reliably distinguished between the objectively scored procedure performance of VES and novices. Reliable and valid performance metrics of RARP are imperative for effective and quality assured surgical training.

Quantifying the "Assistant Effect" in Robotic-Assisted Radical Prostatectomy (RARP): Measures of Technical Performance.

PURPOSE: Surgeons are reliant on the bedside assistant during robotic surgeries. Using a modified global rating scale (GRS), we aim to assess the association between an assistant's technical skill on surgeon performance in Robotic-Assisted Radical Prostatectomy (RARP). METHODS: Prospective, intraoperative video from RARP cases at three centers were collected. Baseline demographic and RARP-experience data were collected from participating surgeons and trainees. The dissection of the prostatic pedicle and neurovascular bundle step (NVB) was analyzed. Expert analysts scored the console surgeon performance using the Global Evaluative Assessment of Robotic Skills (GEARS), and the bedside assistant performance using a modified Objective Structured Assessment of Technical Skills (aOSATS). The primary outcome is the association between console surgeon performance, as measured by GEARS, and assistant skill, as measured by aOSATS. Spearman's rho correlations were used to test the relationship between assistant and surgeon technical performance, and a multivariable linear regression model was created to test this association while controlling for patient factors. RESULTS: 92 RARP cases were available for the analysis, comprising 14 console surgeons and 22 different bedside assistants. In only 5 (5.4%) cases, the neurovascular bundle step was completed by a trainee, and in 13 (14.1%) of cases, a staff-level surgeon acted as the bedside assistant. aOSATS score was significantly associated with robotic console experience (P = 0.011), and prior laparoscopic experience (P < 0.001). Assistant aOSATS score showed a weak but significant correlation with surgeon GEARS score during the neurovascular bundle step (spearman's rho = 0.248, P = 0.028). On linear regression, aOSATS remained a significant predictor of console surgeon performance (P = 0.016), after controlling for patient age and BMI, prostate volume, tumor stage, and presence of nerve-sparing. CONCLUSIONS: This is the first study to assess the association between assistant technical skill and surgeon performance in RARP. Additionally, we have provided validity evidence for a modified OSATS global rating scale for training and assessing bedside assistant performance.

Real-time assessment of learning curve for robot-assisted laparoscopic prostatectomy.

INTRODUCTION: The learning curves analysed to date for robot-assisted laparoscopic prostatectomy are based on arbitrary cut-offs of the total cases. METHODS: We analysed a large dataset of robot-assisted laparoscopic prostatectomies from a single centre between 2008 and 2019 for assessment of the learning curve for perioperative outcomes with respect to time and individual cases. RESULTS: A total of 1,406 patients were evaluated, with mean operative time 198.08 minutes and mean console time 161.05 minutes. A plot of operative time and console time showed an initial decline followed by a near-constant phase. The inflection points were detected at 1,398 days (308th case) for operative time and 1,470 days (324th case) for console time, with a declining trend of 8.83 minutes and 7.07 minutes, respectively, per quarter-year (p<0.001). Mean estimated blood loss showed a 70.04% reduction between the start (214.76ml) and end (64.35ml) (p<0.001). The complication rate did not vary with respect to time (p=0.188) or the number of procedures (p=0.354). There was insufficient evidence to claim that the number of operations (p=0.326), D'Amico classification (p=0.114 for intermediate versus low; p=0.158 for high versus low) or time (p=0.114) was associated with the odds of positive surgical margins. CONCLUSIONS: It takes about 300 cases and nearly 4 years to standardise operative and console times, with a requirement of around 80 cases per annum for a single surgical team in the initial years to optimise the outcomes of robot-assisted laparoscopic prostatectomy.

Design and Validation of a Low-Cost, High-Fidelity Model for Urethrovesical Anastomosis in Radical Prostatectomy.

OBJECTIVE: We sought to develop and validate a low-cost, high-fidelity robotic surgical model for the urethrovesical anastomosis component of the robot-assisted laparoscopic radical prostatectomy. MATERIALS AND METHODS: A novel simulation model was constructed using a 3D-printed model of the male bony pelvis from CT scan data and silicone molds to recreate the soft tissue aspects. Using a da Vinci Si surgical robot, urology faculty and trainees performed simulated urethrovesical anastomosis. Each participant was given 12 minutes to complete the simulation. A survey established face validity, content validity, and acceptability. Simulation runs were evaluated by three blinded reviewers. The anastomosis was graded by two reviewers for suture placement accuracy and anastomosis quality. These factors were compared with robotic experience to establish construct validity. RESULTS: Twenty participants took part in the initial validation of this model. Groups were defined as experts (surgical faculty), intermediate (fellows and chief residents), and novices (junior residents). Likert scores (1-5 scale, top score 5) examining face validity, content validity, and acceptability were 3.49 ± 0.43, 4.15 ± 0.23, and 4.02 ± 0.19, respectively. Construct validity was excellent based on the model's ability to stratify groups. All evaluated metrics were statistically different between the three levels of training. Total material cost was $2.50 per model. CONCLUSIONS: We developed a novel low-cost robotic simulation of the urethrovesical anastomosis for robot-assisted radical prostatectomy. The model discerns robotic skill level across all levels of training and was found favorable by participants showing excellent face, content, and construct validities.

The Australian laparoscopic radical prostatectomy learning curve.

BACKGROUND: International estimates of the laparoscopic radical prostatectomy (LRP) learning curve extend to as many as 1000 cases, but is unknown for Fellowship-trained Australian surgeons. METHODS: Prospectively collected data from nine Australian surgeons who performed 2943 consecutive LRP cases was retrospectively reviewed. Their combined initial 100 cases (F100, n = 900) were compared to their second 100 cases (S100, n = 782) with two of nine surgeons completing fewer than 200 cases. RESULTS: The mean age (61.1 versus 61.1 years) and prostate specific antigen (7.4 versus 7.8 ng/mL) were similar between F100 and S100. D'Amico's high-, intermediate- and low-risk cases were 15, 59 and 26% for the F100 versus 20, 59 and 21% for the S100, respectively. Blood transfusions (2.4 versus 0.8%), mean blood loss (413 versus 378 mL), mean operating time (193 versus 163 min) and length of stay (2.7 versus 2.4 days) were all lower in the S100. Histopathology was organ confined (pT2) in 76% of F100 and 71% of S100. Positive surgical margin (PSM) rate was 18.4% in F100 versus 17.5% in the S100 (P = 0.62). F100 and S100 PSM rates by pathological stage were similar with pT2 PSM 12.2 versus 9.5% (P = 0.13), pT3a PSM 34.8 versus 40.5% (P = 0.29) and pT3b PSM 52.9 versus 36.4% (P = 0.14). CONCLUSION: There was no significant improvement in PSM rate between F100 and S100 cases. Perioperative outcomes were acceptable in F100 and further improved with experience in S100. Mentoring can minimize the LRP learning curve, and it remains a valid minimally invasive surgical treatment for prostate cancer in Australia even in early practice.

Towards development and validation of an intraoperative assessment tool for robot-assisted radical prostatectomy training: results of a Delphi study

ABSTRACT Introduction As urology training shifts toward competency-based frameworks, the need for tools for high stakes assessment of trainees is crucial. Validated assessment metrics are lacking for many robot-assisted radical prostatectomy (RARP). As it is quickly becoming the gold standard for treatment of localized prostate cancer, the development and validation of a RARP assessment tool for training is timely. Materials and methods We recruited 13 expert RARP surgeons from the United States and Canada to serve as our Delphi panel. Using an initial inventory developed via a modified Delphi process with urology residents, fellows, and staff at our institution, panelists iteratively rated each step and sub-step on a 5-point Likert scale of agreement for inclusion in the final assessment tool. Qualitative feedback was elicited for each item to determine proper step placement, wording, and suggestions. Results Panelist's responses were compiled and the inventory was edited through three iterations, after which 100% consensus was achieved. The initial inventory steps were decreased by 13% and a skip pattern was incorporated. The final RARP stepwise inventory was comprised of 13 critical steps with 52 sub-steps. There was no attrition throughout the Delphi process. Conclusions Our Delphi study resulted in a comprehensive inventory of intraoperative RARP steps with excellent consensus. This final inventory will be used to develop a valid and psychometrically sound intraoperative assessment tool for use during RARP training and evaluation, with the aim of increasing competency of all trainees.

Modular Training for Robot-Assisted Radical Prostatectomy: Where to Begin?

OBJECTIVE: Effective training is paramount for patient safety. Modular training entails advancing through surgical steps of increasing difficulty. This study aimed to construct a modular training pathway for use in robot-assisted radical prostatectomy (RARP). It aims to identify the sequence of procedural steps that are learnt before surgeons are able to perform a full procedure without an intervention from mentor. DESIGN: This is a multi-institutional, prospective, observational, longitudinal study. We used a validated training tool (RARP Score). Data regarding surgeons' stage of training and progress were collected for analysis. A modular training pathway was constructed with consensus on the level of difficulty and evaluation of individual steps. We identified and recorded the sequence of steps performed by fellows during their learning curves. SETTING AND PARTICIPANTS: We included 15 urology fellows from UK, Europe, and Australia. RESULTS: A total of 15 surgeons were assessed by mentors in 425 RARP cases over 8 months (range: 7-79) across 15 international centers. There were substantial differences in the sequence of RARP steps according to the chronology of the procedure, difficulty level, and the order in which surgeons actually learned steps. Steps were not attempted in chronological order. The greater the difficulty, the later the cohort first undertook the step (p = 0.021). The cohort undertook steps of difficulty level I at median case number 1. Steps of difficulty levels II, III, and IV showed more variation in median case number of the first attempt. We recommend that, in the operating theater, steps be learned in order of increasing difficulty. A new modular training route has been designed. This incorporates the steps of RARP with the following order of priority: difficulty level > median case number of first attempt > most frequently undertaken in surgical training. CONCLUSIONS: An evidence-based modular training pathway has been developed that facilitates a safe introduction to RARP for novice surgeons.

Prospective Assessment of Learning Curve of Holmium Laser Enucleation of the Prostate for Treatment of Benign Prostatic Hyperplasia Using a Multidimensional Approach.

PURPOSE: Despite being endorsed in most guidelines, wide adoption of holmium laser enucleation of the prostate is hindered by learning difficulties. We prospectively assessed the learning curve using a multidimensional approach. MATERIALS AND METHODS: We prospectively report all perioperative safety and efficacy outcome measures as well as the need for reoperation and continence status. Case difficulty and learning curve characterization variables were considered, looking for predictors of different outcome measures. Our analysis included the first 313 procedures done by a total of 3 surgeons. RESULTS: Prostate volume and the number of previously performed cases independently predicted operative and enucleation efficiency (mean ± SD 0.76 ± 0.36 and 1.2 ± 0.6 gm per minute, respectively). Both measures plateaued only after the first 40 procedures. The mean percent reduction in postoperative prostate specific antigen was 80% ± 19%. A significantly lower decrease was independently predicted by the transrectal ultrasound depiction of a grossly multinodular prostate (p = 0.000, R2 = 0.59). Perioperative safety measures showed significant improvement after the first and second 20 procedures apart from hospital stay and catheter time. Urinary incontinence was reported in 89 (28.5%), 26 (8.3%) and 7 cases (2.2%) at 1, 4 and 12 months, respectively. Only the number of previously performed cases predicted urinary incontinence at 1 month, which was significantly reduced following the first 20 procedures (plateau) (OR 0.99, 95% CI 0.98-0.999, p = 0.03). The I-PSS (International Prostate Symptom Score) preoperative storage subdomain (OR 0.7, 95% CI 0.4-0.9, p = 0.04), case density (OR 0.3, 95% CI 0.2-0.6, p = 0.01) and number of previously performed cases (OR 0.97, 95% CI 0.98-0.999, p = 0.02) predicted urinary incontinence at 4 months, which was significantly reduced after the first and second 20 procedures. Persistent urinary incontinence at 12 months was significantly associated with fewer previously performed cases (median 60, range 0 to 211 vs 20, range 0 to 99, p = 0.04) with no plateauing through the curve. CONCLUSIONS: Plateauing through the learning curve of holmium laser enucleation of the prostate is a moving target. Looking at different outcome measures, different levels of experience are needed to reach the plateau. Preoperative prostate volume, the number of previously performed cases and case density are the main influential factors in the curve. Urinary incontinence is the most relevant clinical outcome that was significantly affected by learning, although its transient nature is assuring.

Structured and Modular Training Pathway for Robot-assisted Radical Prostatectomy (RARP): Validation of the RARP Assessment Score and Learning Curve Assessment.

BACKGROUND: Use of robot-assisted radical prostatectomy (RARP) for prostate cancer is increasing. Structured surgical training and objective assessment are critical for outcomes. OBJECTIVE: To develop and validate a modular training and assessment pathway via Healthcare Failure Mode and Effect Analysis (HFMEA) for trainees undertaking RARP and evaluate learning curves (LCs) for procedural steps. DESIGN, SETTING, AND PARTICIPANTS: This multi-institutional (Europe, Australia, and United States) observational prospective study used HFMEA to identify the high-risk steps of RARP. A specialist focus group enabled validation. Fifteen trainees who underwent European Association of Urology robotic surgery curriculum training performed RARP and were assessed by mentors using the tool developed. Results produced LCs for each step. A plateau above score 4 indicated competence. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We used a modular training and assessment tool (RARP Assessment Score) to evaluate technical skills. LCs were constructed. Multivariable Kruskal-Wallis, Mann-Whitney U, and κ coefficient analyses were used. RESULTS AND LIMITATIONS: Five surgeons were observed for 42 console hours to map steps of RARP. HFMEA identified 84 failure modes and 46 potential causes with a hazard score ≥8. Content validation created the RARP Assessment Score: 17 stages and 41 steps. The RARP Assessment Score was acceptable (56.67%), feasible (96.67%), and had educational impact (100%). Fifteen robotic surgery trainees were assessed for 8 mo. In 426 RARP cases (range: 4-79), all procedural steps were attempted by trainees. Trainees were assessed with the RARP Assessment Score by their expert mentors, and LCs for individual steps were plotted. LCs demonstrated plateaus for anterior bladder neck transection (16 cases), posterior bladder neck transection (18 cases), posterior dissection (9 cases), dissection of prostatic pedicle and seminal vesicles (15 cases), and anastomosis (17 cases). Other steps did not plateau during data collection. CONCLUSIONS: The RARP Assessment Score based on HFMEA methodology identified critical steps for focused RARP training and assessed surgeons. LCs demonstrate the experience necessary to reach a level of competence in technical skills to protect patients. PATIENT SUMMARY: We developed a safety and assessment tool to gauge the technical skills of surgeons performing robot-assisted radical prostatectomy. Improvement was monitored, and measures of progress can be used in future to guide mentors when training surgeons to operate safely.

Supervisor volume affects oncological outcomes of trainees performing open radical prostatectomy.

BACKGROUND: The relationship between biochemical failure (BF) rate and surgeon experience following open radical prostatectomy (ORP) has been well established, but BF when ORP is performed by urology trainees who are supervised by urologists of differing volume has not. We aimed to compare the oncological outcomes from ORP when a urology trainee as primary operator and is supervised by a high- or low-volume consultant urologist. METHODS: Using a centralized whole of population dataset, created through the Victorian Radical Prostatectomy Registry, patients were classified as either those where a consultant was the primary operator, a urology trainee was the primary operator and supervised by a high-volume consultant or those where a urology trainee was supervised by a low-volume consultant. BF- and prostate cancer (PCa)-specific mortality was compared between these latter two groups and the consultant-only group. RESULTS: We found BF- and PCa-specific mortality rate to be poorer when ORP was performed by a urology trainee supervised by a low-volume consultant compared with consultant-led surgery (hazard ratio (HR) = 1.33, P = 0.022; subhazard ratio (SHR) = 2.31, P = 0.010, respectively). When a urology trainee, as primary operator, was supervised by a high-volume consultant, there was no statistical difference in BF- or PCa-specific mortality rate following ORP compared with consultant-led surgery (HR = 1.19, P = 0.234; SHR = 1.53, P = 0.346, respectively). There was a trend evident with decreasing supervisor volume leading to worse oncological and mortality outcomes for trainee-led cases. CONCLUSION: This study demonstrates the value of high-volume and fellowship-trained urologists in performing and teaching ORP. As outcomes are increasingly scrutinized with audits, the best strategy for clinicians to maintain standards and optimal patient outcomes is to understand these elements and direct trainees to appropriate centres for training and fellowships.

Assessment of virtual reality robotic simulation performance by urology resident trainees.

OBJECTIVES: To examine resident performance on the Mimic dV-Trainer (MdVT; Mimic Technologies, Inc., Seattle, WA) for correlation with resident trainee level (postgraduate year [PGY]), console experience (CE), and simulator exposure in their training program to assess for internal bias with the simulator. DESIGN: Residents from programs of the Southeastern Section of the American Urologic Association participated. Each resident was scored on 4 simulator tasks (peg board, camera targeting, energy dissection [ED], and needle targeting) with 3 different outcomes (final score, economy of motion score, and time to complete exercise) measured for each task. These scores were evaluated for association with PGY, CE, and simulator exposure. SETTING: Robotic skills training laboratory. PARTICIPANTS: A total of 27 residents from 14 programs of the Southeastern Section of the American Urologic Association participated. RESULTS: Time to complete the ED exercise was significantly shorter for residents who had logged live robotic console compared with those who had not (p = 0.003). There were no other associations with live robotic console time that approached significance (all p ≥ 0.21). The only measure that was significantly associated with PGY was time to complete ED exercise (p = 0.009). No associations with previous utilization of a robotic simulator in the resident's home training program were statistically significant. CONCLUSIONS: The ED exercise on the MdVT is most associated with CE and PGY compared with other exercises. Exposure of trainees to the MdVT in training programs does not appear to alter performance scores compared with trainees who do not have the simulator.

Development and initial assessment of a training program for laparoscopic radical prostatectomy. First module: the urethrovesical anastomosis.

PURPOSE: We present our experience in the design and development of a training program in laparoscopic radical prostatectomy (LRP), and the validation of the first steps of the program by objective measurement of the attendants' skills improvement and subjective evaluation of its contents. MATERIALS AND METHODS: Our training model on LRP has a total duration of 42 hours, divided in two modules of 21 hours each, performed 1 month apart. Data included in the present study were obtained from the first module of our course. It begins with acquisition of basic knowledge in ergonomics and instrument concepts, after which the attendants develop essential laparoscopic dexterities through the performance of hands-on physical simulator tasks. During the second and third day, urologists performed urethrovesical anastomosis also in the physical simulator. Attendants' skills improvement was measured during the first module by registering surgical times and suturing quality of the anastomosis, the latter by means of a leak test. At the end of the training program, a subjective evaluation questionnaire on the different didactic and organizational aspects was handed out to the attendants. RESULTS: By comparing first and last anastomosis, we observed a significant decrease in surgical times (minutes) (T1 40.1±4.6 vs T6 24.01±3.34; P≤0.005) and an increase in intraluminal leak pressure (mm Hg) (T1 8.27±7.33 vs T6 21.09±6.72; P≤0.005). We obtained a highly positive score on all questions concerning the different topics and techniques included in the training program (≥9 points over 10). Regarding the attendants' self-assessment of acquired abilities, 78.3% considered themselves capacitated to perform the trained procedures on patients. CONCLUSIONS: Training obtained during the first module of our training model significantly decreased performance times for ex vivo urethrovesical anastomosis, simultaneously increasing its quality. In addition, validation of the training model was also demonstrated by the highly scored evaluation resulting from the attendants' assessment.

A manpower calculus: the implications of SUO fellowship expansion on oncologic surgeon case volumes.

INTRODUCTION: Society of Urologic Oncology (SUO)-accredited fellowship programs have undergone substantial expansion. This study developed a mathematical model to estimate future changes in urologic oncologic surgeon (UOS) manpower and analyzed the effect of those changes on per-UOS case volumes. MATERIALS AND METHODS: SUO fellowship program directors were queried as to the number of positions available on an annual basis. Current US UOS manpower was estimated from the SUO membership list. Future manpower was estimated on an annual basis by linear senescence of existing manpower combined with linear growth of newly trained surgeons. Case-volume estimates for the 4 surgical disease sites (prostate, kidney/renal pelvis, bladder, and testes) were obtained from the literature. The future number of major cases was determined from current volumes based upon the US population growth rates and the historic average annual change in disease incidence. Two models were used to predict future per-UOS major case volumes. Model 1 assumed the current distribution of cases between nononcologic surgeons and UOS would continue. Model 2 assumed a progressive redistribution of cases over time such that in 2043 100% of major urologic cancer cases would be performed by UOSs. RESULTS: Over the 30-year period to "manpower steady-state" SUO-accredited UOSs practicing in the United States have the potential to increase from approximately 600 currently to 1,650 in 2043. During this interval, case volumes are predicted to change 0.97-, 2.4-, 1.1-, and 1.5-fold for prostatectomy, nephrectomy, cystectomy, and retroperitoneal lymph node dissection, respectively. The ratio of future to current total annual case volumes is predicted to be 0.47 and 0.9 for models 1 and 2, respectively. The number of annual US practicing graduates necessary to achieve a future to current case-volume ratio greater than 1 is 25 and 49 in models 1 and 2, respectively. CONCLUSIONS: The current number of SUO fellowship trainees has the potential to decrease future per-UOS case volumes relative to current levels. Redistribution of existing case volume or a decrease in the annual number of trainees or both would be required to insure sufficient surgical volumes for skill maintenance and optimal patient outcomes.

Learning curve assessment of robot-assisted radical prostatectomy compared with open-surgery controls from the premier perspective database.

INTRODUCTION: The primary aims of this study were to assess the learning curve effect of robot-assisted radical prostatectomy (RARP) in a large administrative database consisting of multiple U.S. hospitals and surgeons, and to compare the results of RARP with open radical prostatectomy (ORP) from the same settings. MATERIALS AND METHODS: The patient population of study was from the Premier Perspective Database (Premier, Inc., Charlotte, NC) and consisted of 71,312 radical prostatectomies performed at more than 300 U.S. hospitals by up to 3739 surgeons by open or robotic techniques from 2004 to 2010. The key endpoints were surgery time, inpatient length of stay, and overall complications. We compared open versus robotic, results by year of procedures, results by case volume of specific surgeons, and results of open surgery in hospitals with and without a robotic system. RESULTS: The mean surgery time was longer for RARP (4.4 hours, standard deviation [SD] 1.7) compared with ORP (3.4 hours, SD 1.5) in the same hospitals (p<0.0001). Inpatient stay was shorter for RARP (2.2 days, SD 1.9) compared with ORP (3.2 days, SD 2.7) in the same hospitals (p<0.0001). The overall complications were less for RARP (10.6%) compared with ORP (15.8%) in the same hospitals, as were transfusion rates. ORP results in hospitals without a robot were not better than ORP with a robot, and pretreatment co-morbidity profiles were similar in all cohorts. Trending of results by year of procedure showed no differences in the three cohorts, but trending of RARP results by surgeon experience showed improvements in surgery time, hospital stay, conversion rates, and complication rates. CONCLUSIONS: During the initial 7 years of RARP development, outcomes showed decreased hospital stay, complications, and transfusion rates. Learning curve trends for RARP were evident for these endpoints when grouped by surgeon experience, but not by year of surgery.

Laparoscopic radical prostatectomy: introduction of training during our first 50 cases.

BACKGROUND: The study aims to assess the initial experience of laparoscopic radical prostatectomy (LRP) in a regional centre in Australia which includes Fellowship training during our first 50 cases. METHODS: Data were collected prospectively from our first 50 consecutive patients who underwent LRP for localized prostate cancer between September 2009 and October 2010. All cases were performed or supervised by the primary surgeon. Patient details, operative details, complications, early oncological and functional outcomes were analysed. RESULTS: The median age was 65 (45-76) years and median preoperative prostate-specific antigen was 7.5 (2.5-23) ng/mL, with palpable disease present in 48%. Using D'Amico's risk stratification, 14%, 74% and 12% were in low, intermediate and high-risk categories, respectively. Forty percent of cases were training cases with a median of 5 (2-8) of 10 operative steps performed by the Fellow. There was one open conversion and no rectal injuries. Mean operative time was 288 (175-440) min and with blood transfusion rate of 6%. Mean length of stay was 2.5 (1-6) days. Positive surgical margin rates for pT2 and pT3 disease were 14% and 52%, respectively, although for the last 25 cases they were 7% and 30%, respectively. Continence rate was 86% at 6 months, and 45% and 33% of preoperatively potent patients were potent after bilateral and unilateral nerve preservation at 6 months. CONCLUSION: LRP has been safely introduced in a regional centre with establishment of a Fellowship training programme, with early results comparable with other open, laparoscopic and robotic series.

Developing a successful robotics program.

PURPOSE OF REVIEW: Advancements in the robotic surgical technology have revolutionized the standard of care for many surgical procedures. The purpose of this review is to evaluate the important considerations in developing a new robotics program at a given healthcare institution. RECENT FINDINGS: Patients' interest in robotic-assisted surgery has and continues to grow because of improved outcomes and decreased periods of hospitalization. Resulting market forces have created a solid foundation for the implementation of robotic surgery into surgical practice. Given proper surgeon experience and an efficient system, robotic-assisted procedures have been cost comparable to open surgical alternatives. Surgeon training and experience is closely linked to the efficiency of a new robotics program. Formally trained robotic surgeons have better patient outcomes and shorter operative times. Training in robotics has shown no negative impact on patient outcomes or mentor learning curves. SUMMARY: Individual economic factors of local healthcare settings must be evaluated when planning for a new robotics program. The high cost of the robotic surgical platform is best offset with a large surgical volume. A mature, experienced surgeon is integral to the success of a new robotics program.

Impact of fellowship training on one-year outcomes of robotic-assisted prostatectomy.

BACKGROUND AND OBJECTIVES: We examined 1-year functional and oncologic outcomes for robotic-assisted laparoscopic prostatectomy (RALP) from a single surgeon entering practice directly from fellowship training. METHODS: We prospectively analyzed the first 100 RALPs performed by one fellowship-trained robotic surgeon. Data included resident involvement during the procedure, perioperative data, and surgical complications (scored using the Clavien grading system). Health-related quality of life (HRQOL) data were captured using the EPIC questionnaire at baseline (prior to surgery) and at 1-year follow-up. RESULTS: Eighty-two patients (82%) had hospital stays of 2 days or less without any postoperative complications, urethral catheter removal was within 14 days of surgery, and none required readmission to the hospital. The overall positive margin rate was 21% (19% for patients with T2 disease). Clavien grades 1 through 4 complication rates, respectively, were 4%, 10%, 1%, and 1%. There were no deaths, reoperations, or bladder neck contractures. One patient (1%) required a blood transfusion within the 90-day perioperative period. At 1-year follow-up, 78% of patients reported wearing no pads; 41.3% of patients with baseline and 1-year follow-up data reported having intercourse. CONCLUSIONS: We provide baseline data pertaining to the morbidity, oncologic efficacy, continence results, and potency outcomes of new surgeons performing RALP.
