RESUMEN
PURPOSE: The purpose of this study was to investigate the effect of a nurse practitioner-led simulation-based education program on nursing knowledge and confidence in the care of patients with a cutaneous continent urinary diversion (Indiana pouch) or orthotopic neobladder. DESIGN: Single-group, before-after study. SUBJECTS AND SETTING: The sample comprised 11 RNs practicing at New York Presbyterian Hospital in New York City. Subjects were predominantly female, ethnically diverse, and held a bachelor's degree. About half of the subjects had less than 3 years of experience, and more than half reported prior experience caring for patients with a urinary diversion. METHODS: Participants completed a demographic survey, and a continent urinary diversion confidence survey and pretest measuring knowledge of nursing care of patients with a urinary diversion. Following baseline data collection, an educational session focused on the irrigation of a continent urinary diversion was made available for participants to review. An onsite simulation experience was scheduled several weeks later. Investigators provided education on proper irrigation of a continent urinary diversion and observed participants' skills when irrigating a continent urinary diversion on a high-fidelity simulated patient mannequin. The simulation intervention was followed by video replay and debrief providing feedback on each participant's performance. At the conclusion of the onsite simulation intervention, participants completed a postintervention confidence survey and a knowledge posttest related to the care of a continent urinary diversion. The Wilcoxon signed rank test was used to analyze baseline and postintervention changes in nursing knowledge and confidence. RESULTS: Participants achieved significant improvements in knowledge (P = .005) and confidence (P = .009) following the simulation-based educational intervention. CONCLUSIONS: A nurse practitioner-led simulation-based educational program for RNs caring for patients with continent urinary diversions demonstrates enhanced nursing knowledge and confidence caring for patients with continent urinary diversions. We anticipate this experience will enhance care we provided to patients undergoing cystectomy and continent cutaneous urinary diversion or orthotopic neobladder construction.

The aim of the study is to report surgical and early functional outcomes of first 100 patients undergoing robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (ICUD) in a single center. The main surgeon (A.P.) attended a modular training program at a referring center mentored by a worldwide-recognized robotic surgeon (P.W.). The program consisted of: (a) 10 h of theoretical lessons; (b) video session (c) step-by-step in vivo modular training. Each procedure was performed as taught, without any technique variation. Demographics, intra-operative data and post-operative complications, along with early functional outcomes, were recorded for each patient. We retrospectively evaluated the first consecutive 100 patients submitted to RARC with totally ICUD from July 2015 to December 2018. Median age at surgery was 69 years (IQR 60-74). 52 (52%), 32 (32%), and 17 (17%) patients received orthotopic neobladder, ileal conduit and uretero-cutaneostomy, respectively. Median operative time was 410 min. A median number of lymph nodes retrieved were 27 and median estimated blood loss was 240 mL with median hospitalization time of 7 days. All procedures were completed successfully without open conversion. A statistically significant improvement was found in the late (30-90 post-operative days) post-operative complications (p = 0.02) and operative time for urinary derivation. At multivariate logistic regression model ASA score ≥ 3 (OR = 4.2, p = 0.002) and number of lymph nodes retrieved (OR = 1.16, p = 0.02) were found to be predictors of 90-day complications. An adequate modular training is paramount to obtain successful results and reduce the learning curve of RARC, as demonstrated by our experience.

INTRODUCTION: Robotic cystectomy with intracorporeal urinary diversion (RCID) is a technically challenging procedure. It is understood that this approach has a learning curve; however, limited studies have characterized this learning curve. The cumulative sum (CUSUM) method plots the learning curve. The aim of this study was to use the CUSUM approach to investigate the number of cases required to reach a consistent, desired performance level for RCID. MATERIALS AND METHODS: Retrospective study of the first 27 and 28 RCID cases performed by two new fellowship trained faculty at two separate institutions from November 2014 to January 2018. Total operating time was calculated and the CUSUM method was used to describe the learning curve, the number of cases needed for a consistent performance level. RESULTS: Twenty-seven and 28 patients were reviewed from two institutions (A and B), with 8 and 7 females, 19 and 21 males and an average age of 66.7 and 67.6 years, respectively. Twelve and ten cases, respectively, had final pathology of stage T3 bladder cancer or higher. The CUSUM curve demonstrated a learning curve of 10 and 11 cases, respectively, when the curve transitioned from steady improvement in OR times (upward slope of curve) to a relative steady state of OR times (plateau of curve). The average lymph node yield, rate of ureteral stricture, and positive margins were also examined with no learning curve noted. CONCLUSION: In RCID, approximately 10 cases were required by robotically trained new faculty to reach a steady-state level of performance.

PURPOSE OF REVIEW: We review historical aspects and current status of the emerging approach of robotic urinary diversion (rUD). Established surgical principles of constructing a low-pressure, large-capacity reservoir are described and the open surgical literature succinctly reviewed to establish the gold standard. Incontinent and continent rUD types [ileal conduit, orthotopic neobladder (all varieties), continent cutaneous diversion, cutaneous ureterostomy] and techniques (extra-corporeal, intra-corporeal) are discussed. Outcomes data (intra-operative, perioperative, intermediate-term, long-term), functional outcomes, complications and learning curve are presented. Outcomes data of open versus robotic urinary diversion are examined. Critiques, improvements, and pros-cons of rUD are discussed. RECENT FINDINGS: Although the majority of centers performing rUD use the extracorporeal technique, use of intra-corporeal rUD is increasing. Although data are yet limited, intra-corporeal rUD may provide some benefits. For rUD, operative times are higher and complication rates comparable with open urinary diversion. SUMMARY: The entire range of urinary diversion surgery has now been replicated robotically. At this writing, extracorporeal urinary diversion techniques still predominate following robotic cystectomy. However, all rUD options can now be performed intra-corporeally with success. As experience increases, the field of robotic urinary diversion is poised to grow.

OBJECTIVE: To assess the potential exposure to complex urologic procedures, specifically urinary diversion, during a gynecologic oncology fellowship. METHODS: We queried the University HealthSystem Consortium (UHC) database to determine the total number of urinary diversions performed from October 2008 to August 2012. This data was used to estimate the mean number of urinary diversions performed each year. Gender, primary diagnosis, type of diversion, gynecologic oncologist involvement, and medical center were explored. RESULTS: Of the nearly 21,000 urinary diversions performed in UHC participating hospitals during the study period, 6180 (29.5%) were performed in women. On average, 1648 urinary diversions are performed in women each year, with gynecologic malignancies accounting for 6.8% of cases. We estimate that a gynecologic oncologist was involved with 87 cases per year at nonprofit academic medical centers in the US. With approximately 112 clinically active fellows per year during the study period, this equates to less than one diversion per clinical fellow per year if cases are equally distributed among centers. However, the majority of urinary diversions with gynecologic oncologist involvement were performed at just a fraction of centers. Thus, only a small contingent of fellows may be getting the greatest exposure to urinary diversions. CONCLUSIONS: The majority of urinary diversions in women in the US are performed for bladder carcinoma by urologists. The estimated number of cases per clinical gynecologic oncology fellow per year is less than one. Strategies to improve fellow exposure to urinary diversion and consideration of alternative surgical training modalities should be explored.

INTRODUCTION: Radical cystectomy is considered the standard treatment for muscle-invasive bladder cancer. Minimally invasive techniques - especially robot-assisted techniques (RARC) - are being increasingly employed for this indication. Herein, we evaluate the current status of RARC and its acceptance in the urological community. RESULTS: The field of RARC is steadily increasing particularly due to an extremely short learning curve for surgeons with previous experience in robot-assisted radical prostatectomy. Lymph node yield has been shown to be adequate in several independent studies, being comparable to that of the open approach. Urinary diversion is most frequently done extracorporeally while several groups have commited themselves to intracorporeal techniques and have already shown excellent results. The perioperative outcome data compare favourably to those of open cystectomy. Short-term and interim oncological data are promising while a final long-term assessment is still lacking. CONCLUSIONS: RARC completed by appropriate urinary diversion is gaining relevance in academic institutions worldwide. The relatively wide availability of the robotic system will further add to this development. Secondary to the final assessment of its oncological efficacy RARC has the potential to become a standard treatment of muscle-invasive bladder cancer since its perioperative efficacy is excellent.

OBJECTIVE: The purpose of this study was to subjectively evaluate the adequacy of the porcine model for training gynecologic oncology fellows. STUDY DESIGN: Following a defined surgical curriculum, fellow-attending pairs operated on female hogs. A predetermined dataset was collected for each procedure. RESULTS: Twenty pigs were operated on. The porcine model was determined to be a good model for laparoscopic lymphadenectomy (11), ureteroneocystostomy (7), repair of vascular injury (11), bowel anastamoses (21), distal pancreatectomy (5), nephrectomy (6), partial hepatectomy (5), diaphram stripping (5), and diaphragmatic resection (4). Two attendings and 1 fellow judged the porcine model to be fair (remaining 11 good) for ileocolonic urinary diversion, mainly due to significant differences in anatomy. Liver mobilization (5) and splenectomy (11) were determined to be fair or poor models by all participants due to the limited attachments in the pig. CONCLUSION: The porcine model is adequate for teaching some ancillary gynecologic oncology surgical procedures and is inadequate for others.

PURPOSE OF REVIEW: There is an obvious discrepancy between the perceived advantages of the different forms of continent urinary diversion from an expert's point of view and the limited utilization of these techniques outside of academic and tertiary referral centers. RECENT FINDINGS: The vast majority of studies are retrospective with numerous confounding factors and often poorly defined outcomes. The rates of postoperative morbidity and need for reoperation varies widely among studies, even for the same procedure. The utilization of continent diversion depends on demographic, socioeconomic, provider-based, and clinical variables, with low case volume and lack of experience probably being the most obvious reasons for avoidance of more complex techniques. In contrast to the prevailing notion that patients undergoing continent diversion have superior quality of life than those receiving a conduit, existing studies fail to show significant advantages of one technique over the other. SUMMARY: The current body of published literature is insufficient to conclude that there is a superior form of urinary diversion in terms of evidence-based medicine. It is quite clear, however, that not all patients are candidates for one type of diversion. The best results are obtained when a comprehensive concept is tailored to the individual patient.

PURPOSE: Operative experience is important in developing surgical skills and technical competency. There is also emerging evidence directly linking increased surgical volume to patient outcomes. Accordingly, resident training should provide the framework for mastery of complex operations. We evaluated the current urological residency experience in performing adult urinary diversion. MATERIALS AND METHODS: The Accreditation Council for Graduate Medical Education-Residency Review for Urology Operative Log Reports were reviewed from 2000 to 2004 with an emphasis on urinary diversion experience. Resident logs were analyzed specifically for all procedures that included CPT codes for continent and incontinent diversions. The logs were compared by year of training and type of urinary diversion. RESULTS: Overall, the total number of urinary diversions performed by graduating residents from 4-year programs has increased from 2,259 (2000 to 2001) to 4,017 (2003 to 2004). In addition, the mean and median number of urinary diversion cases among residents completing training have remained relatively constant. For graduating urology residents in 2003 to 2004, the mean (median) number of continent urinary diversion and incontinent urinary diversion cases were only 6.7 (3.0) and 9.5 (4), respectively. CONCLUSIONS: Current Accreditation Council for Graduate Medical Education data suggest the average urology resident has limited exposure to urinary diversion in general, and even less experience with more complex continent urinary diversion. These results suggest that many urology residency programs may not have sufficient volume to provide residents with a broad experience in urinary diversion, and alternative strategies to ensure proper training should be explored.
