RESUMEN

PURPOSE: Coronavirus disease (COVID-19) has profoundly impacted residency training and education. To date, there has not been any broad assessment of urological surgery residency changes and concerns during the COVID-19 pandemic. MATERIALS AND METHODS: The Society of Academic Urologists distributed a questionnaire to urology residency program directors on March 30, 2020 exploring residency program changes related to the COVID-19 pandemic. Descriptive statistics are presented. A qualitative analysis of free response questions was undertaken. A post hoc analysis of differences related to local COVID-19 incidence is described. RESULTS: The survey was distributed to 144 residency programs with 65 responses for a 45% response rate. Reserve staffing had started in 80% of programs. Patient contact time had decreased significantly from 4.7 to 2.1 days per week (p <0.001). Redeployment was reported by 26% of programs. Sixty percent of programs reported concern that residents will not meet case minimums due to COVID-19. Wellness activities centered on increased communication. All programs had begun to use videoconferencing and the majority planned to continue. Programs in states with a higher incidence of COVID-19 were more likely to report resident redeployment (48% vs 11%, p=0.002) and exposure to COVID-19 positive patients (70% vs 40%, p=0.03), and were less likely to report concerns regarding exposure (78% vs 97%, p=0.02) and personal protective equipment availability (62% vs 89%, p=0.02). CONCLUSIONS: As of April 1, 2020 the COVID-19 pandemic had resulted in significant changes in urology residency programs. These findings inform a rapidly changing landscape and aid in the development of best practices.

RESUMEN

PURPOSE: The RAZOR (Randomized Open versus Robotic Cystectomy) trial revealed noninferior 2-year progression-free survival for robotic radical cystectomy. This update was performed with extended followup for 3 years to determine potential differences between the approaches. We also report 3-year overall survival and sought to identify factors predicting recurrence, and progression-free and overall survival. MATERIALS AND METHODS: We analyzed the per protocol population of 302 patients from the RAZOR study. Cumulative recurrence was estimated using nonbladder cancer death as the competing risk event and the Gray test was applied to assess significance in differences. Progression-free survival and overall survival were estimated by the Kaplan-Meier method and compared with the log rank test. Predictors of outcomes were determined by Cox proportional hazard analysis. RESULTS: Estimated progression-free survival at 36 months was 68.4% (95% CI 60.1-75.3) and 65.4% (95% CI 56.8-72.7) in the robotic and open groups, respectively (p=0.600). At 36 months overall survival was 73.9% (95% CI 65.5-80.5) and 68.5% (95% CI 59.8-75.7) in the robotic and open groups, respectively (p=0.334). There was no significant difference in the cumulative incidence rates of recurrence (p=0.802). Patient age greater than 70 years, poor performance status and major complications were significant predictors of 36-month progression-free survival. Stage and positive margins were significant predictors of recurrence, and progression-free and overall survival. Surgical approach was not a significant predictor of any outcome. CONCLUSIONS: This analysis showed no difference in recurrence, 3-year progression-free survival or 3-year overall survival for robotic vs open radical cystectomy. It provides important prospective data on the oncologic efficacy of robotic radical cystectomy and high level data for patient counseling.

RESUMEN

BACKGROUND: The emergence of the coronavirus disease (COVID-19) pandemic in March 2020 created unprecedented challenges in the provision of scheduled ambulatory cancer care. As a result, there has been a renewed focus on video-based telehealth consultations as a means to continue ambulatory care. OBJECTIVE: The aim of this study is to analyze the change in video visit volume at the University of California, San Francisco (UCSF) Comprehensive Cancer Center in response to COVID-19 and compare patient demographics and appointment data from January 1, 2020, and in the 11 weeks after the transition to video visits. METHODS: Patient demographics and appointment data (dates, visit types, and departments) were extracted from the electronic health record reporting database. Video visits were performed using a HIPAA (Health Insurance Portability and Accountability Act)-compliant video conferencing platform with a pre-existing workflow. RESULTS: In 17 departments and divisions at the UCSF Cancer Center, 2284 video visits were performed in the 11 weeks before COVID-19 changes were implemented (mean 208, SD 75 per week) and 12,946 video visits were performed in the 11-week post-COVID-19 period (mean 1177, SD 120 per week). The proportion of video visits increased from 7%-18% to 54%-72%, between the pre- and post-COVID-19 periods without any disparity based on race/ethnicity, primary language, or payor. CONCLUSIONS: In a remarkably brief period of time, we rapidly scaled the utilization of telehealth in response to COVID-19 and maintained access to complex oncologic care at a time of social distancing.

RESUMEN

BACKGROUND: Preventable complications and readmissions after cystectomy may be detectable via postoperative monitoring of patient-reported outcomes (PROs). However, no study has defined meaningful PROs or the use of mobile communication devices (mobile health [mHealth]) to capture them. The objectives of this study were to determine which high-priority PROs influence patients' perioperative experience, what processes influence these outcomes, how patients and caregivers differ in their experiences, and how mHealth might be used to improve outcomes. METHODS: Forty-five semistructured, in-depth interviews were conducted with readmitted cystectomy patients, caregivers, and providers with an interview guide that addressed perioperative education, symptoms, function, and the potential for mHealth interventions. Among 15 patients, 10 had an interviewed partner. A thematic analysis of interviews conducted with readmitted patients, caregivers, and providers was performed to examine processes that affected perioperative care and readmission and to determine how mHealth interventions might be implemented. RESULTS: Readmitted patients and caregivers ranged in age from 33 to 78 years and were diverse in race and stage. The providers included a diverse representation of physicians, nurses, and other specialists. Cystectomy preoperative education was overwhelming and lacked personalization, and this contributed to a fundamental lack of knowledge regarding normal and abnormal symptoms after surgery. Three connecting themes were identified: 1) cystectomy education overload, 2) a need to define normal symptoms, and 3) education with incremental learning through mHealth. CONCLUSIONS: A personalized mHealth intervention addressing themes of education overload, the definition of normality, and incremental learning could be realized through mHealth technology and provide the right information for the right patient at the right time.

RESUMEN

BACKGROUND: Radical cystectomy is the surgical standard for invasive bladder cancer. Robot-assisted cystectomy has been proposed to provide similar oncological outcomes with lower morbidity. We aimed to compare progression-free survival in patients with bladder cancer treated with open cystectomy and robot-assisted cystectomy. METHODS: The RAZOR study is a randomised, open-label, non-inferiority, phase 3 trial done in 15 medical centres in the USA. Eligible participants (aged ≥18 years) had biopsy-proven clinical stage T1-T4, N0-N1, M0 bladder cancer or refractory carcinoma in situ. Individuals who had previously had open abdominal or pelvic surgery, or who had any pre-existing health conditions that would preclude safe initiation or maintenance of pneumoperitoneum were excluded. Patients were centrally assigned (1:1) via a web-based system, with block randomisation by institution, stratified by type of urinary diversion, clinical T stage, and Eastern Cooperative Oncology Group performance status, to receive robot-assisted radical cystectomy or open radical cystectomy with extracorporeal urinary diversion. Treatment allocation was only masked from pathologists. The primary endpoint was 2-year progression-free survival, with non-inferiority established if the lower bound of the one-sided 97·5% CI for the treatment difference (robotic cystectomy minus open cystectomy) was greater than -15 percentage points. The primary analysis was done in the per-protocol population. Safety was assessed in the same population. This trial is registered with ClinicalTrials.gov, number NCT01157676. FINDINGS: Between July 1, 2011, and Nov 18, 2014, 350 participants were randomly assigned to treatment. The intended treatment was robotic cystectomy in 176 patients and open cystectomy in 174 patients. 17 (10%) of 176 patients in the robotic cystectomy group did not have surgery and nine (5%) patients had a different surgery to that they were assigned. 21 (12%) of 174 patients in the open cystectomy group did not have surgery and one (1%) patient had robotic cystectomy instead of open cystectomy. Thus, 302 patients (150 in the robotic cystectomy group and 152 in the open cystectomy group) were included in the per-protocol analysis set. 2-year progression-free survival was 72·3% (95% CI 64·3 to 78·8) in the robotic cystectomy group and 71·6% (95% CI 63·6 to 78·2) in the open cystectomy group (difference 0·7%, 95% CI -9·6% to 10·9%; pnon-inferiority=0·001), indicating non-inferiority of robotic cystectomy. Adverse events occurred in 101 (67%) of 150 patients in the robotic cystectomy group and 105 (69%) of 152 patients in the open cystectomy group. The most common adverse events were urinary tract infection (53 [35%] in the robotic cystectomy group vs 39 [26%] in the open cystectomy group) and postoperative ileus (33 [22%] in the robotic cystectomy group vs 31 [20%] in the open cystectomy group). INTERPRETATION: In patients with bladder cancer, robotic cystectomy was non-inferior to open cystectomy for 2-year progression-free survival. Increased adoption of robotic surgery in clinical practice should lead to future randomised trials to assess the true value of this surgical approach in patients with other cancer types. FUNDING: National Institutes of Health National Cancer Institute.

RESUMEN

PURPOSE: Costly surveillance and treatment of bladder cancer can lead to financial toxicity, a treatment related financial burden. Our objective was to define the prevalence of financial toxicity among patients with bladder cancer and identify delays in care and its effect on health related quality of life. MATERIALS AND METHODS: We identified patients with bladder cancer in the University of North Carolina Health Registry/Cancer Survivorship Cohort. Financial toxicity was defined as agreement with having "to pay more for medical care than you can afford." Health related quality of life was measured using general and cancer specific validated questionnaires. Statistical analyses were performed using the Fisher exact test and the Student t-test. RESULTS: A total of 138 patients with bladder cancer were evaluated. Median age was 66.9 years, 75% of the patients were male and 89% were white. Of the participants 33 (24%) endorsed financial toxicity. Participants who were younger (p = 0.02), black (p = 0.01), reported less than a college degree (p = 0.01) and had noninvasive disease (p = 0.04) were more likely to report financial toxicity. On multivariable analysis only age was a significant predictor of financial toxicity. Patients who endorsed financial toxicity were more likely to report delaying care (39% vs 23%, p = 0.07) due to the inability to take time off work or afford general expenses. On general health related quality of life questionnaires patients with financial toxicity reported worse physical and mental health (p = 0.03 and <0.01, respectively), and lower cancer specific health related quality of life (p = 0.01), physical well-being (p = 0.01) and functional well-being (p = 0.05). CONCLUSIONS: Financial toxicity is a major concern among patients with bladder cancer. Younger patients were more likely to experience financial toxicity. Those who endorsed financial toxicity experienced delays in care and poorer health related quality of life, suggesting that treatment costs should have an important role in medical decision making.

RESUMEN

PURPOSE: Pressure on physicians to increase productivity is rising in parallel with administrative tasks, regulations, and the use of electronic health records (EHRs). Physician extenders and clinical pathways are already in use to increase productivity and reduce costs and burnout, but other strategies are required. We evaluated whether implementation of medical scribes in an academic urology clinic would affect productivity, revenue, and patient/provider satisfaction. METHODS: Six academic urologists were assigned scribes for 1 clinic day per week for 3 months. Likert-type patient and provider surveys were developed to evaluate satisfaction with and without scribes. Matched clinic days in the year prior were used to evaluate changes in productivity and physician/hospital charges and revenue. RESULTS: After using scribes for 3 months, providers reported increased efficiency (p value = 0.03) and work satisfaction (p value = 0.03), while seeing a mean 2.15 more patients per session (+ 0.96 return visits, + 0.99 new patients, and + 0.22 procedures), contributing to an additional 2.6 wRVUs, $542 in physician charges, and $861 in hospital charges per clinic session. At a gross collection rate of 36%, actual combined revenue was + $506/session, representing a 26% increase in overall revenue. At a cost of $77/session, the net financial impact was + $429 per clinic session, resulting in a return-to-investment ratio greater than 6:1, while having no effect on patient satisfaction scores. Additionally, with scribes, clinic encounters were closed a mean 8.9 days earlier. CONCLUSIONS: Implementing medical scribes in academic urology practices may be useful in increasing productivity, revenue, and provider satisfaction, while maintaining high patient satisfaction.

RESUMEN

PURPOSE: Men with clinically localized prostate cancer face an archetypal "preference sensitive" treatment decision. A shared decision making process incorporating patient values and preferences is paramount. We evaluated the benefit of a novel decision making application, and investigated associations between patient preferences and treatment choice. MATERIALS AND METHODS: We used a novel, web based application that provides education, preference measurement and personalized decision analysis for patients with newly diagnosed prostate cancer. Preferences are measured using conjoint analysis. The application ranks treatment options according to their "fit" (expected value) based on clinical factors and personal preferences, and serves as the basis for shared decision making during the consultation. We administered the decisional conflict scale before and after completion of the application. Additionally, we compared post-visit perceptions of shared decision making between a baseline "usual care" cohort and a cohort seen after the application was integrated into clinical practice. RESULTS: A total of 109 men completed the application before their consultation, and had decisional conflict measured before and after use. Overall decisional conflict decreased by 37% (p <0.0001). Analysis of the decisional conflict subscales revealed statistically significant improvements in all 5 domains. Patients completing the decision making application (33) felt more included in (88% vs 57%, p=0.01) and jointly responsible for (94% vs 52%, p <0.0001) the decision about further treatment compared to those receiving usual care (24). More patients who completed the application strongly agreed that different treatment options were discussed (94% vs 74%, p=0.02). CONCLUSIONS: Implementation of this web based intervention was associated with decreased decisional conflict and enhanced elements of shared decision making.

RESUMEN

PURPOSE: Although associated with an overall favorable survival rate, the heterogeneity of non-muscle invasive bladder cancer (NMIBC) affects patients' rates of recurrence and progression. Risk stratification should influence evaluation, treatment and surveillance. This guideline attempts to provide a clinical framework for the management of NMIBC. MATERIALS AND METHODS: A systematic review utilized research from the Agency for Healthcare Research and Quality (AHRQ) and additional supplementation by the authors and consultant methodologists. Evidence-based statements were based on body of evidence strength Grade A, B, or C and were designated as Strong, Moderate, and Conditional Recommendations with additional statements presented in the form of Clinical Principles or Expert Opinions.(1) RESULTS: A risk-stratified approach categorizes patients into broad groups of low-, intermediate-, and high-risk. Importantly, the evaluation and treatment algorithm takes into account tumor characteristics and uniquely considers a patient's response to therapy. The 38 statements vary in level of evidence, but none include Grade A evidence, and many were Grade C. CONCLUSION: The intensity and scope of care for NMIBC should focus on patient, disease, and treatment response characteristics. This guideline attempts to improve a clinician's ability to evaluate and treat each patient, but higher quality evidence in future trials will be essential to improve level of care for these patients.

RESUMEN

PURPOSE: The proportion of women in urology has increased from less than 0.5% in 1981 to 10% today. Furthermore, 33% of students matching in urology are now female. In this analysis we characterize the female workforce in urology compared to that of men with regard to income, workload and job satisfaction. MATERIALS AND METHODS: We collaborated with the American Urological Association to survey its domestic membership of practicing urologists regarding socioeconomic, workforce and quality of life issues. A total of 6,511 survey invitations were sent via e-mail. The survey consisted of 26 questions and took approximately 13 minutes to complete. Linear regression models were used to evaluate bivariable and multivariable associations with job satisfaction and compensation. RESULTS: A total of 848 responses (660 or 90% male, 73 or 10% female) were collected for a total response rate of 13%. On bivariable analysis female urologists were younger (p <0.0001), more likely to be fellowship trained (p=0.002), worked in academics (p=0.008), were less likely to be self-employed and worked fewer hours (p=0.03) compared to male urologists. On multivariable analysis female gender was a significant predictor of lower compensation (p=0.001) when controlling for work hours, call frequency, age, practice setting and type, fellowship training and advance practice provider employment. Adjusted salaries among female urologists were $76,321 less than those of men. Gender was not a predictor of job satisfaction. CONCLUSIONS: Female urologists are significantly less compensated compared to male urologists after adjusting for several factors likely contributing to compensation. There is no difference in job satisfaction between male and female urologists.

RESUMEN

BACKGROUND: Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. METHODS: The records of 413 patients collected by the International Renal Cell Carcinoma-Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan-Meier estimate and Cox regression analyses investigated the impact of TC on CSS in addition to established clinicopathological predictors. RESULTS: VTT was solid in 225 patients and friable in 188 patients. Median CSS was 50 months in solid and 45 months in friable VTT. TC showed no significant association with metastatic spread, pT stage, perinephric fat invasion, and higher Fuhrman grade. Survival analysis and Cox regression rejected TC as prognostic marker for CSS. CONCLUSIONS: In the largest cohort published so far, TC seems not to be independently associated with survival in RCC patients and should therefore not be included in risk stratification models. J.

RESUMEN

Robot-assisted surgery has become a widely used surgical approach in the management of urologic malignancies. With its initial experience in the treatment of prostate cancer, the technology rapidly expanded to other urologic malignancies including bladder cancer. Since its introduction in 2003, robot-assisted radical cystectomy has seen refinement and increased penetration over the last decade. Furthermore, urologic surgeons have expanded its use to perform urinary diversions. The concept of intracorporeal urinary diversion is still in development but continues to see increased refinement among high volume academic centers.

RESUMEN

PURPOSE: A significant proportion of renal masses removed for suspected malignancy are histologically benign with the probability inversely proportional to lesion size. To our knowledge the number of preoperatively misclassified benign renal masses treated with nephrectomy is currently unknown. Given the increasing incidence and decreasing average size of renal cell carcinoma, this burden is likely increasing. We estimated the population level burden of surgically removed, preoperatively misclassified benign renal masses in the United States. MATERIALS AND METHODS: We systematically reviewed the literature for studies of pathological findings of renal masses removed for suspected renal cell carcinoma based on preoperative imaging through July 1, 2014. We excluded studies that did not describe benign pathology and with masses not stratified by size, and in which pathology results were based on biopsy. SEER data were queried for the incidence of surgically removed renal cell carcinomas in 2000 to 2009. RESULTS: A total of 19 studies of tumor pathology based on size met criteria for review. Pooled estimates of the proportion of benign histology in our primary analysis (American studies only and 1 cm increments) were 40.4%, 20.9%, 19.6%, 17.2%, 9.2% and 6.4% for tumors less than 1, 1 to less than 2, 2 to less than 3, 3 to less than 4, 4 to 7 and greater than 7, respectively. The estimated number of surgically resected benign renal masses in the United States from 2000 to 2009 increased by 82% from 3,098 to 5,624. CONCLUSIONS: These estimates suggest that the population level burden of preoperatively misclassified benign renal masses is substantial and increasing rapidly, paralleling increases in surgically resected small renal cell carcinoma. This study illustrates an important and to our knowledge previously unstudied dimension of overtreatment that is not directly quantified in contemporary surveillance data.

RESUMEN

PURPOSE: Metastatic renal cell carcinoma can be clinically diverse in terms of the pattern of metastatic disease and response to treatment. We studied the impact of metastasis and location on cancer specific survival. MATERIALS AND METHODS: The records of 2,017 patients with renal cell cancer and tumor thrombus who underwent radical nephrectomy and tumor thrombectomy from 1971 to 2012 at 22 centers in the United States and Europe were analyzed. Number and location of synchronous metastases were compared with respect to patient cancer specific survival. Multivariable Cox regression models were used to quantify the impact of covariates. RESULTS: Lymph node metastasis (155) or distant metastasis (725) was present in 880 (44%) patients. Of the patients with distant disease 385 (53%) had an isolated metastasis. The 5-year cancer specific survival was 51.3% (95% CI 48.6-53.9) for the entire group. On univariable analysis patients with isolated lymph node metastasis had a significantly worse cancer specific survival than those with a solitary distant metastasis. The location of distant metastasis did not have any significant effect on cancer specific survival. On multivariable analysis the presence of lymph node metastasis, isolated distant metastasis and multiple distant metastases were independently associated with cancer specific survival. Moreover higher tumor thrombus level, papillary histology and the use of postoperative systemic therapy were independently associated with worse cancer specific survival. CONCLUSIONS: In our multi-institutional series of patients with renal cell cancer who underwent radical nephrectomy and tumor thrombectomy, almost half of the patients had synchronous lymph node or distant organ metastasis. Survival was superior in patients with solitary distant metastasis compared to isolated lymph node disease.

RESUMEN

PURPOSE: The impact of cardiopulmonary bypass in level III-IV tumor thrombectomy on surgical and oncologic outcomes is unknown. We determine the impact of cardiopulmonary bypass on overall and cancer specific survival, as well as surgical complication rates and immediate outcomes in patients undergoing nephrectomy and level III-IV tumor thrombectomy with or without cardiopulmonary bypass. MATERIALS AND METHODS: We retrospectively analyzed 362 patients with renal cell cancer and with level III or IV tumor thrombus from 1992 to 2012 at 22 U.S. and European centers. Cox proportional hazards models were used to compare overall and cancer specific survival between patients with and without cardiopulmonary bypass. Perioperative mortality and complication rates were assessed using logistic regression analyses. RESULTS: Median overall survival was 24.6 months in noncardiopulmonary bypass cases and 26.6 months in cardiopulmonary bypass cases. Overall survival and cancer specific survival did not differ significantly in both groups on univariate analysis or when adjusting for known risk factors. On multivariate analysis no significant differences were seen in hospital length of stay, Clavien 1-4 complication rate, intraoperative or 30-day mortality and cancer specific survival. Limitations include the retrospective nature of the study. CONCLUSIONS: In our multi-institutional analysis the use of cardiopulmonary bypass did not significantly impact cancer specific survival or overall survival in patients undergoing nephrectomy and level III or IV tumor thrombectomy. Neither approach was independently associated with increased mortality on multivariate analysis. Greater surgical complications were not independently associated with the use of cardiopulmonary bypass.

RESUMEN

The purpose of the RAZOR (randomized open vs robotic cystectomy) study is to compare open radical cystectomy (ORC) vs robot-assisted RC (RARC), pelvic lymph node dissection (PLND) and urinary diversion for oncological outcomes, complications and health-related quality of life (HRQL) measures with a primary endpoint of 2-year progression-free survival (PFS). RAZOR is a multi-institutional, randomized, non-inferior, phase III trial that will enrol at least 320 patients with T1-T4, N0-N1, M0 bladder cancer with ≈160 patients in both the RARC and ORC arms at 15 participating institutions. Data will be collected prospectively at each institution for cancer outcomes, complications of surgery and HRQL measures, and then submitted to trial data management services Cancer Research and Biostatistics (CRAB) for final analyses. To date, 306 patients have been randomized and accrual to the RAZOR trial is expected to conclude in 2014. In this study, we report the RAZOR trial experimental design, objectives, data safety, and monitoring, and accrual update. The RAZOR trial is a landmark study in urological oncology, randomizing T1-T4, N0-N1, M0 patients with bladder cancer to ORC vs RARC, PLND and urinary diversion. RAZOR is a multi-institutional, non-inferiority trial evaluating cancer outcomes, surgical complications and HRQL measures of ORC vs RARC with a primary endpoint of 2-year PFS. Full data from the RAZOR trial are not expected until 2016-2017.

RESUMEN

PURPOSE: To determine the impact of preoperative nutritional status on the development of surgical complications following cystectomy using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). METHODS: We performed a retrospective review of the NSQIP 2005-2012 Participant Use Data Files. ACS-NSQIP collects data on 135 variables, including pre- and intraoperative data and 30-day postoperative complications and mortality on all major surgical procedures at participating institutions. Preoperative albumin (<3.5 or >3.5 g/dl), weight loss 6 months before surgery (>10 %), and body mass index (BMI) were identified as nutritional variables within the database. The overall complication rate was calculated, and predictors of complications were identified using multivariable logistic regression models. RESULTS: A total of 1,213 patients underwent cystectomy for bladder cancer between 2005 and 2012. The overall 30-day complication rate was 55.1 % (n = 668). While 14.7 % (n = 102) had a preoperative albumin <3.5 g/dL, 3.4 % had >10 % weight loss in the 6 months prior to surgery and the mean BMI was 28 kg/m(2). After controlling for age, sex, medical comorbidities, medical resident involvement, operation year, operative time, and prior operation, only albumin <3.5 g/dl was a significant predictor of experiencing a postoperative complication (p = 0.03). This remained significant when albumin was evaluated as a continuous variable (p = 0.02). CONCLUSIONS: Poor nutritional status measured by serum albumin is predictive of an increased rate of surgical complications following radical cystectomy. This finding supports the importance of preoperative nutritional status in this population and highlights the need for the development of effective nutritional interventions in the preoperative setting.

RESUMEN

PURPOSE: Most urologic training programs use robotic prostatectomy (RP) as an introduction to teach residents appropriate robotic technique. However, concerns may exist regarding differences in RP outcomes with resident involvement. Our objective was therefore to evaluate whether resident involvement affects complications, operative time, or length of stay (LOS) following RP. METHODS: Using the National Surgical Quality Improvement Program database (2005-2011), we identified patients who underwent RP, stratified them by resident presence or absence during surgery, and compared hospital LOS, operative time, and postoperative complications using bivariable and multivariable analyses. A secondary analysis comparing outcomes of interest across postgraduate year (PGY) levels was also performed. RESULTS: A total of 5,087 patients who underwent RPs were identified, in which residents participated in 56%, during the study period. After controlling for potential confounders, resident present and absent groups were similar in 30-day mortality (0.0 vs. 0.2%, p = 0.08), serious morbidity (1.8 vs. 2.1%, p = 0.33), and overall morbidity (5.1 vs. 5.4%, p = 0.70). While resident involvement did not affect LOS, operative time was longer when residents were present (median 208 vs. 183 min, p < 0.001). Similar findings were noted when assessing individual PGY levels. CONCLUSIONS: Regardless of PGY level, resident involvement in RPs appears safe and does not appear to affect postoperative complications or LOS. While resident involvement in RPs does result in longer operative times, this is necessary for the learning process.

RESUMEN

Robotic-assisted radical cystectomy (RARC) is a challenging procedure that potentially offers the patient decreased perioperative morbidity. With careful patient selection and attention to surgical detail, one can learn to efficiently and safely perform RARC with extracorporeal diversion. As one develops further expertise with RARC, patient selection criteria can be liberalized and intracorporeal diversion can be performed. The accumulated experience of our institution and other high-volume institutions are reviewed with attention to the technical details that yield a safe and efficient robotic cystectomy.

RESUMEN

BACKGROUND: Bladder cancer is notable for a striking heterogeneity of disease-specific risks. Among the approximately 75% of incident cases found to be superficial to the muscularis propria at the time of presentation (non-muscle-invasive bladder cancer), the risk of progression to the lethal phenotype of muscle-invasive disease is strongly associated with stage and grade of disease. Given the suggestion of an increasing percentage of low-risk cases in hospital-based registry data in recent years, the authors hypothesized that population-based data may reveal changes in the stage distribution of early-stage cases. METHODS: Surveillance, Epidemiology, and End Results (SEER) data were used to examine trends for the stage-specific incidence of bladder cancer between 1988 and 2006, adjusted for age, race, and sex, using Joinpoint and nonparametric tests. RESULTS: The adjusted incidence rate of papillary noninvasive (Ta) predominantly low grade (77%) disease was found to increase from 5.52 to 9.09 per 100,000 population (P < .0001), with an average annual percentage change of +3.3. Over the same period, concomitant, albeit smaller, decreases were observed for flat in situ (Tis) and lamina propria-invasive (T1) disease (2.57 to 1.19 and 6.65 to 4.61 per 100,000 population [both P < .0001]; average annual percent change of -5.0 and -1.6, respectively). The trend was most dramatic among patients in the oldest age strata, suggesting a previously unappreciated cohort phenomenon. CONCLUSIONS: The findings of the current study should motivate further epidemiological investigations of differential associations of genetic and environmental factors with different bladder cancer phenotypes as well as further scrutiny of clinical practice guideline recommendations for the growing subgroup of predominantly older patients with lower-risk disease.
