It's complicated: The relationship of non-narcotic medications and postoperative opioid use in radical cystectomy patients.

INTRODUCTION: The effect of individual non-narcotic analgesics in cystectomy enhanced recovery after surgery (ERAS) is unknown. Additionally, many non-narcotic medications are associated with side effects pertinent to the cystectomy population. To better understand the actual use and utility of these medications, we sought to characterize the association between non-narcotic medications and milligram morphine equivalent (MME) narcotic score during the postoperative inpatient stay. METHODS: We reviewed 260 consecutive ERAS cystectomy patients. The MME impact of non-narcotic compliance and cumulative dose of medication received was evaluated separately with general linear models. We also assessed relationship of non-narcotic compliance to patient reported pain score, length of stay (LOS), and time to return of bowel function (ROBF) and performed manual review of postoperative documentation to identify reasons for medication noncompliance. RESULTS: Compliance with postoperative acetaminophen, gabapentin, and ketorolac was low. There was an inverse relationship between ketorolac dose and MME on postoperative day 1 (-0.026 MME/mg; P = 0.004) and postoperative day 2 (-0.33 MME/mg; P < 0.001). Compliance with ketorolac was associated with lower MME on postoperative day 1 (26.1 MME v. 33.6 MME; P = 0.023). There were no such associations identified with gabapentin or acetaminophen. Gabapentin compliance was associated with earlier ROBF (3.7 days v. 4.3 days; P = 0.006). Ketorolac compliance was associated with lower pain score on POD1 (3.25 VAS v. 4.07 VAS; P = 0.019) and POD2 (3.05 VAS v. 3.85 VAS; P = 0.040) There was no association between medication compliance and LOS. The most common reasons identified for non-compliance with gabapentin and ketorolac were renal function concerns (38% and 40% respectively), bleeding concerns with ketorolac (20%) and concerns for neurologic adverse effect with gabapentin (16%). CONCLUSION: Compliance with non-narcotic medications in our ERAS cystectomy protocol was poor. There was a modest association with ketorolac and postoperative MME but no association with gabapentin or acetaminophen. Further study will clarify the role of these medications for cystectomy patients. Component specific analysis of protocolized care is valuable and may alter care pathways.

Interruptions in bladder cancer care during the COVID-19 public health emergency.

BACKGROUND: Academic and community urology centers participating in a pragmatic clinical trial in non-muscle-invasive bladder cancer completed monthly surveys assessing restrictions in aspects of bladder cancer care due to the COVID-19 Public Health Emergency. Our objective was to describe pandemic-related restrictions on bladder cancer care. METHODS: We invited 32 sites participating in a multicenter pragmatic bladder cancer trial to complete monthly surveys distributed through REDCap beginning in May 2020. These surveys queried sites on whether they were experiencing restrictions in the use of elective surgery, transurethral resection of bladder tumors (TURBT), radical cystectomy, office cystoscopy, and intravesical bacillus Calmette-Guerin (BCG) availability. Responses were collated with descriptive statistics. RESULTS: Of 32 eligible sites, 21 sites had at least a 50% monthly response rate over the study period and were included in the analysis. Elective surgery was paused at 76% of sites in May 2020, 48% of sites in January 2021, and 52% of sites in January 2022. Over those same periods, coinciding with COVID-19 incidence waves, TURBT was restricted at 10%, 14%, and 14% of sites, respectively, radical cystectomy was restricted at 10%, 14%, and 19% of sites, respectively, and cystoscopy was restricted at 33%, 0%, and 10% of sites, respectively. CONCLUSIONS: Bladder cancer care was minimally restricted compared with more pronounced restrictions seen in general elective surgeries during the COVID-19 pandemic.

Persistent opioid and benzodiazepine use after radical cystectomy in enhanced recovery after surgery (ERAS) patients.

OBJECTIVES: Opioid use, misuse, and diversion is of paramount concern in the United States. Radical cystectomy is typically managed with some component of opioid pain control. We evaluated persistent opioid and benzodiazepine use after radical cystectomy and assessed the impact of their preoperative use on this outcome. We also explored associations between preoperative use and perioperative outcomes. METHODS AND MATERIALS: We used prospectively maintained data from our enhanced recovery after surgery (ERAS) cystectomy database and the Prescription Reporting with Immediate Medication Utilization Mapping (PRIMUM) database to identify controlled substance prescriptions for radical cystectomy patients. We separated patients by frequency of preoperative opioid and/or benzodiazepine prescriptions (0, 1, 2+) and used these cohorts to explore persistent use (prescription 3-12 months after surgery) alongside perioperative outcomes. RESULTS: Our cohort included 257 patients undergoing cystectomy at a single institution from 2017 to 2021. Preoperative opioid and benzodiazepine prescriptions were documented for 120 (46.7%) and 26 (10.1%) patients, respectively. Persistent opioid use was observed in 20 (14.6%) of opioid-naive patients (no prescriptions in 9 months prior to surgery) while 13 (19.7%) patients with 1 preoperative prescription and 28 (51.9%) patients with 2 or more preoperative prescriptions demonstrated persistent use. New persistent benzodiazepine use occurred in 6 (2.6%) patients. Overall persistent benzodiazepine use was present in 11 (4.3%) patients. In a multivariable model, preoperative opioid and benzodiazepine prescriptions were associated with persistent opioid use (P < 0.001; P = 0.027 respectively). No association was identified between preoperative opioid or benzodiazepine usage and perioperative outcomes including length of stay, return of bowel function, inpatient opioid usage, inpatient or discharge complications, readmissions, or emergency department visits. Inpatient pain scores were noted to be higher in patients with ≥ 2 preoperative opioid prescriptions (P = 0.037). CONCLUSIONS: Persistent opioid use was present in 23.7% of patients, with a new persistent use rate of 14.6%. Benzodiazepine use was less frequent than opioids, with a small number demonstrating new persistent use. Preoperative opioid and benzodiazepine use is associated with persistent opioid use postoperatively. Preoperative opioid and benzodiazepine use did not affect perioperative outcomes in our cohort.

Impact of dedicated renal enhanced recovery after surgery (RERAS) program on postoperative opioid consumption and evaluation of surgeon-specific compliance to the program.

INTRODUCTION AND OBJECTIVE: Enhanced Recovery After Surgery (ERAS) protocols have been increasingly applied to urologic surgeries such as cystectomy and prostatectomy, though research defining protocols and outcomes for renal ERAS programs (RERAS) for nephrectomy remains limited. We aim to assess perioperative outcomes following implementation of our RERAS protocol modified from ERAS society cystectomy guidelines, as well as describe compliance with protocol guidelines. METHODS: We performed a retrospective cohort analysis of 400 patients who underwent partial or radical nephrectomy between October 2017 and August 2020. RERAS protocol was initiated September 30, 2018, and patients were categorized into pre- and post-RERAS implementation cohorts based on surgery date. Perioperative outcomes including complications, 30-day readmissions, length of stay, and opioid consumption were compared across pre- and post-RERAS cohorts. Protocol compliance was reported based on adherence to program recommendations. RESULTS: Among 400 patients included in analysis, the pre-RERAS cohort included 133 patients and the post-RERAS cohort included 267 patients. There were no differences in overall complications (P = 0.354) and 30-day readmissions (P = 0.078). Length of stay (P < 0.001) and postoperative opioid consumption (P < 0.001) were significantly reduced post-RERAS. We observed an increase in compliance with RERAS recommendations over time (P< 0.001). CONCLUSION: RERAS implementation was associated with decreased length of stay and opioid usage, underscoring the benefits of program adoption in an era of opioid dependence and strained hospital capacity. Successful initiation of a RERAS protocol requires intentional organization and buy in from all providers involved.

Testis Cancer Care in North Carolina: Implications for Real-World Evidence and Cancer Surveillance.

INTRODUCTION: Contemporary testis cancer management requires fastidious adherence to clinical guidelines and care principles, especially for those pursuing active surveillance (AS). However, real-world testis cancer care remains largely undescribed. Accordingly, we sought to assess the rigor of evaluation and monitoring among men with testis cancer. PATIENTS AND METHODS: Using North Carolina Central Cancer Registry data linked to insurance claims, we selected adult males diagnosed with primary testis cancer from 2003 to 2013. After identifying demographics, care setting, histology, stage, and index management, we evaluated the receipt of tumor markers, imaging, and clinic visits during initial evaluation and subsequent monitoring with respect to contemporaneous clinical guidelines. Care patterns were compared using chi-squared testing and multivariable logistic regression. RESULTS: Of 2526 men with primary testis cancer, we assembled a cohort of 487 with seminoma (59.3%) or nonseminoma (40.7%), losing most to a lack of insurance or continuous coverage. The cohort was predominantly white (92.4%) and had stage I disease (87.9%). Overall, 18.9% had complete tumor markers, staging imaging, and visits with 2 relevant specialists as recommended during their initial evaluation. For subsequent monitoring, 17.5% of patients with seminoma on active surveillance met minimal thresholds for recommended testing and follow-up during the first year vs. 21.9% and 34.9% of patients with seminoma treated with adjuvant radiation and chemotherapy, respectively. For nonseminoma, 10.1% of men on active surveillance met the minimal thresholds for recommended monitoring compared with 60.4% and 62.0% of those treated with surgery and chemotherapy, respectively. Recommended monitoring also differed by academic vs. community setting and receipt of recommended evaluation (P < .05). CONCLUSIONS: From real-world data, the evaluation and monitoring of patients with testis cancer appears substandard. Ongoing data and quality gaps highlight potential challenges with generating real-world evidence and ensuring adequate surveillance in this population.

Racial and Socioeconomic Disparities in MRI-Fusion Biopsy Utilization to Assess for Prostate Cancer.

OBJECTIVE: To evaluate whether racial disparities in MRI-Bx usage persisted after correction for socioeconomic, demographic, and clinical factors. METHODS: This is a retrospective cohort study of patients who received either MRI-Bx or systematic biopsy (SB) within a single academic medical center between January 2018 - June 2020. For each patient, socioeconomic variables including household income, education, percent below poverty, and unemployment were estimated using 2015 American Community Survey census-tract level data. Chi-square analysis was used to examine differences in clinical and demographic characteristics between the two groups. The Benjamini-Hochberg procedure was used to control false discovery rate (FDR) for multiple testing. RESULTS: Eighteen percent of Black men (53/295) received MRI-Bx while 41% (228/561) of white men received MRI-Bx. Patients coming from highly impoverished areas were less likely to receive MRI-Bx, 25% vs 75%, respectively. In multivariate analysis, race remained significantly different across MRI-Bx and SB groups. Clinical factors including family history, DRE, BMI, and prostate volume were not significantly different between patients receiving MRI-Bx and SB. CONCLUSION: Black men are less likely to receive MRI-Bx than white men, even after adjusting for clinical and socioeconomic characteristics. Further work is necessary to identify and study methods to increase equity in PCa diagnostic testing.

Surgeon-administered Transversus Abdominis Plane (TAP) Block is Associated With Decreased Opioid Usage and Length of Stay Following Radical Cystectomy.

OBJECTIVE: To study the effect of surgeon-administered Transversus Abdominis Plane block (sTAP) on opioid usage and length of stay (LOS). METHODS: Starting in April 2018, two surgeons at our institution gradually introduced sTAP for radical cystectomy (RC) patients. We performed a retrospective observational cohort analysis of RC patients catalogued in a prospectively maintained database using the Enhanced Recovery After Surgery Interactive Auditing System. Two surgeons adopted the sTAP block technique in April 2018. We included patients undergoing RC for bladder malignancy under Enhanced Recovery After Surgery protocol between January 2017 and August 2020. Primary outcomes included LOS, and postoperative day (POD) 0-3 total opioids consumption measured by morphine milligram equivalents (MME). Multivariable linear or logistic models evaluated the association of TAP with outcomes while controlling for potential confounders. RESULTS: Among 178 patients included in analysis, 84 patients underwent sTAP block and 94 did not. Multivariable analysis demonstrated significantly lower POD 0-3 total opioid usage (106.4 vs 192.2 MME, P = .004), and mean LOS (5.6 vs 7.7 days, P <.001) among the sTAP group. CONCLUSION: sTAP appears to be an effective adjunct to RC care associated with improved LOS, and POD 0-3 opioid consumption. Further studies are needed to optimize TAP block technique and anesthetic composition.

Lessons Learned: Social Determinants of Health Screening Pilot in 2 Urology Clinics.

INTRODUCTION: Unmet social needs lead to adverse health outcomes and contribute to health inequities. Efforts to screen for social determinants of health (SDOH) have occurred primarily within primary care. Here, we describe the feasibility of implementing a workflow for SDOH screening within 2 urology clinics in Charlotte, North Carolina. METHODS: Our pilot was adapted from the WE CARE Model, which integrates a referral to community resources for patients identified with social needs and an optional followup with a navigator for additional assistance. Patients were screened with the validated Healthy Opportunities SDOH tool to assess food, housing, utilities, transportation and physical safety needs; 40 patients were screened at 2 urology clinics, totaling 80 patients. Surveys were sent to 16 clinicians and staff who participated in the pilot to assess feasibility of implementation. RESULTS: In all, 24/80 patients (30%) were screened for 1 or more social needs, with food and housing being the most frequent; 20/24 patients with social need (83%) successfully received a community resource guide, and 13 of those patients also requested a referral. All survey respondents either agreed or strongly agreed that screening was valuable and allowed them to better understand the needs of their patients. They also felt that understanding SDOH aligns with departmental goals and mission. CONCLUSIONS: Our results suggest that SDOH screening within a urological setting is feasible, and dedicated support staff should be available to ensure adequate followup for patients with unmet needs. Future work is needed to expand resources for patients and optimize workflow for clinicians.

Genomic analysis of response to bacillus Calmette-Guérin (BCG) treatment in high-grade stage 1 bladder cancer patients.

BACKGROUND: Intravesical bacillus Calmette-Guérin (BCG) therapy is standard treatment for high-risk non-muscle invasive bladder cancer (NMIBC) but overall efficacy is low, and no reliable predictive biomarkers currently exist to refine patient selection. We performed genomic analysis on high-grade (HG) T1 NMIBCs to determine if response to therapy is predicted by certain mutational and/or expressional changes. METHODS: Patients with HG T1 NMIBC treated with induction BCG were stratified by response into durable and non-durable responders. Baseline tumor samples were subjected to targeted DNA sequencing and whole-exome RNAseq. Genomic variants differing significantly between response groups were analyzed using Ingenuity Pathway Analysis (IPA) software. Variant selection was refined to target potential biomarker candidates for responsiveness to BCG. RESULTS: Among 42 patients, the median follow-up was 51.7 months and 40.5% (n=17) were durable BCG responders. Deleterious mutations in the RNA sequence of JCHAIN, S100A7, CLEC2B, and ANXA10 were more common in non-durable responders. Mutations in MCL1 and MSH6 detected on targeted sequencing were more commonly found in durable responders. Of all deleterious DNA and RNA mutations identified, only MCL1 was significantly associated with longer recurrence free survival (RFS) (P=0.031). CONCLUSIONS: Differences in the genomic profiles of HG T1 NMIBC tumors exist between those who show durable response to BCG and those who do not. Using pathway analysis, those differences imply upregulation of several interconnected inflammatory pathways among responders. Specific variants identified here, namely MCL1, are candidates for further study and, if clinically validated, may serve as useful biomarkers in the future.

Racial Disparities in Prostate Specific Antigen Screening and Referral to Urology in a Large, Integrated Health Care System: A Retrospective Cohort Study.

PURPOSE: Contemporary trends and racial disparities in prostate cancer screening and referral to urology for prostate cancer risk are not well characterized, despite consensus that Black men are at higher risk for poor prostate cancer outcomes. The objective of this study was to characterize current racial disparities in prostate cancer screening and referral from primary care to urology for prostate cancer concern within our large, integrated health care system. MATERIALS AND METHODS: This retrospective cohort study used data from Atrium Health's enterprise data warehouse, which includes patient information from more than 900 care locations across North Carolina, South Carolina and Georgia. We included all men seen in the ambulatory or outpatient setting between 2014 and 2019 who were ≥40 years old. Clinical and demographic data were collected for all men, including age and race. Racial outcomes were reported for all groups with >2% representation in the population. Between-group comparisons were determined using chi-squared analysis, Wilcoxon rank sum testing and multivariable logistic regression, with significance defined as p <0.05. RESULTS: We observed a significant decrease in prostate specific antigen testing across all age and racial groups in a cohort of 606,985 men at Atrium Health, including 87,189 Black men, with an overall relative decline of 56%. As compared to White men, Black men were more likely to undergo prostate specific antigen testing (adjusted OR 1.24, 95% CI 1.22-1.26) and be referred to urology for prostate cancer (adjusted OR 1.94, 95% CI 1.75-2.16). CONCLUSIONS: There was a continued significant decline in prostate cancer screening between 2014 and 2019. Despite having modestly elevated odds of being screened for prostate cancer compared to White men, Black men are relatively underscreened when considering that those who undergo prostate specific antigen screening are more likely to be referred by primary care to urology for additional prostate cancer diagnostic evaluation.

Clinical Utility of Postneoadjuvant Chemotherapy Computerized Tomography for Muscle Invasive Urothelial Bladder Cancer.

INTRODUCTION: For muscle invasive bladder cancer, computerized tomography scans are often used before cystectomy to optimize surgical decision planning. The aim of this study is to evaluate the clinical value of postneoadjuvant chemotherapy computerized tomography in patients with localized bladder cancer before cystectomy. METHODS: All T2-3N0 patients with urothelial bladder cancer who completed cisplatin based neoadjuvant chemotherapy were retrospectively analyzed. On postneoadjuvant chemotherapy computerized tomography patients with tumor progression, nodal involvement, metastatic disease and noncancer findings were determined, and subsequent surgical decision making was evaluated. RESULTS: Of 79 cases 21.5% had a new finding on postneoadjuvant chemotherapy scan of which false-positive rates for nodal and metastatic disease were 100%. The frequency of novel findings on postneoadjuvant computerized tomography were 4 (5.1%) with tumor progression, 6 (7.6%) newly discovered enlarged nodes, 8 (10.1%) suspicious for distant metastases and 3 (3.8%) noncancer related conditions. Only 3.8% (3) had alterations in original cystectomy plans exclusively due to tumor progression and 100% of the cohort underwent cystectomy. Overall survival was not associated with new findings (3-year OS 77.4% vs 74%, p=0.473). Median time from postneoadjuvant chemotherapy scan to cystectomy was statistically delayed for patients with new radiographic findings vs those with consistent preneoadjuvant chemotherapy scans (29.5 vs 51 days; p=0.014). CONCLUSIONS: Compared to the preneoadjuvant chemotherapy scans, our data suggests that postneoadjuvant chemotherapy computerized tomography scans discover new findings in approximately 21.5% of cases, but this rarely changes preoperative plans, is not associated with overall survival and is frequently associated with false-positive results.

Association of 5-Alpha Reductase Inhibitor Use with Prostate Specific Antigen Level at the Time of Urology Referral in a Retrospective Cohort at a Large, Integrated Health Care System.

INTRODUCTION: 5-Alpha reductase inhibitor (5-ARI) use leads to a 50% decline in serum prostate specific antigen (PSA) without a concomitant decrease in prostate cancer (PCa) risk. We hypothesize that failure to account for the effect of 5-ARI use on serum PSA leads to increased PCa risk at urology referral among 5-ARI users. METHODS: This is a retrospective cohort study for the years 2018-2019. Atrium Health is a large, vertically integrated health system with over 900 care locations in North Carolina and South Carolina. Men ≥40 years old during 2018-2019 who had a PSA test performed were included. We determined differences in corrected serum PSA level at the time of referral to urology. 5-ARI users and nonusers were compared using the chi-square test, Student's t-test and gamma regression. RESULTS: From 2018-2019, there were 91,368 men who underwent PSA testing, including 2,939 5-ARI users. At referral, 5-ARI users had similar uncorrected median PSA (5.8 vs 5.6 ng/ml, p=0.05). After correcting for the effect of 5-ARIs on PSA, 5-ARI users had a median PSA of 11.6 ng/ml at urology referral, compared to 5.6 ng/ml in nonusers. CONCLUSIONS: Men taking 5-ARIs have higher corrected serum PSA at time of referral to urology. As the unadjusted PSA at referral to urology for PCa risk was similar between 5-ARI users and nonusers, this indicates that the effect of 5-ARI use on serum PSA levels is not routinely accounted for when assessing PCa risk.

Impact of Multidisciplinary Audit of Enhanced Recovery After Surgery (ERAS)® Programs at a Single Institution.

BACKGROUND: As Enhanced Recovery After Surgery (ERAS®) programs expand across numerous subspecialties, growth and sustainability on a system level becomes increasingly important and may benefit from reporting multidisciplinary and financial data. However, the literature on multidisciplinary outcome analysis in ERAS is sparse. This study aims to demonstrate the impact of multidisciplinary ERAS auditing in a hospital system. Additionally, we describe developing a financial metric for use in gaining support for system-wide ERAS adoption and sustainability. METHODS: Data from HPB, colorectal and urology ERAS programs at a single institution were analyzed from a prospective ERAS Interactive Audit System (EIAS) database from September 2015 to June 2019. Clinical 30-day outcomes for the ERAS cohort (n = 1374) were compared to the EIAS pre-ERAS control (n = 311). Association between improved ERAS compliance and improved outcomes were also assessed for the ERAS cohort. The potential multidisciplinary financial impact was estimated from hospital bed charges. RESULTS: Multidisciplinary auditing demonstrated a significant reduction in postoperative length of stay (LOS) (1.5 days, p < 0.001) for ERAS patients in aggregate and improved ERAS compliance was associated with reduced LOS (coefficient - 0.04, p = 0.004). Improved ERAS compliance in aggregate also significantly associated with improved 30-day survival (odds ratio 1.04, p = 0.001). Multidisciplinary analysis also demonstrated a potential financial impact of 44% savings (p < 0.001) by reducing hospital bed charges across all specialties. CONCLUSIONS: Multidisciplinary auditing of ERAS programs may improve ERAS program support and expansion. Analysis across subspecialties demonstrated associations between improved ERAS compliance and postoperative LOS as well as 30-day survival, and further suggested a substantial combined financial impact.

Epidemiology and survival outcome of adult kidney, bladder, and prostate rhabdomyosarcoma: A SEER database analysis.

Rhabdomyosarcoma (RMS) is rare in adulthood, accounting for 2%-5% of adult soft tissue tumors, and less than 20% occur in genitourinary organs. Given its rarity, survival data on adult kidney, bladder, and prostate RMSs is limited. In this population-based analysis, we performed an analysis of all adult RMS cases reported in Surveillance, Epidemiology, and End Results (SEER) database to understand prognostic factors among kidney, bladder, and prostate RMS. A query of the SEER database was performed from 1973 to 2016 for patients >18 of age with RMS. The final cohort consisted of 14 kidney, 35 bladder, and 21 prostate RMS cases in the adult population. Demographic, treatment, and survival data were obtained. Analysis was performed using Fisher's exact test, survival analysis, and model. The median (range) age of diagnosis for adult bladder RMS was 65 years old (19-84) compared to 52.5 (28-68) and 42 (19-87) for kidney and prostate (p = 0.007). About 78.6% of patients underwent surgical intervention. Five-year overall survival (OS) for adult kidney, bladder, and prostate RMS are 17.1% (2.9-41.6%), 22.2% (9.4-38.4%), and 33.0 (12.8-55.0%), respectively. OS was not statistically associated with primary site (p = 0.209). On multivariable analysis, compared to adult bladder RMS, kidney RMS had a higher incidence of mortality (HR: 2.16, 95% CI 1.03-4.53, p = 0.041). Incidence of mortality from prostate RMS was not significantly different from bladder RMS (HR: 0.70, 95% CI 0.30-1.65, p = 0.411). Extent of disease (HR: 5.17, 95% CI 2.09-12.79, p < 0.001) and older age (HR 1.03, 95% CI 1.01-1.04, p = 0.002) were adverse prognostic factors for OS. Overall survival at 5 years for adult kidney, bladder, and prostate RMS is poor. Localized disease and younger age are prognostic factors for improved outcomes in adult RMS. Hence, early diagnosis and intervention appear paramount to improved survival for this rare malignancy in adulthood.

Safety and effectiveness of percutaneous renal cryoablation with conscious sedation.

OBJECTIVE: To investigate complications and treatment failure rates of percutaneous renal cryoablation (PRC) for small renal masses under local anaesthesia and conscious sedation (LACS), to assess the safety and effectiveness of this approach, as PRC is typically performed under general anaesthesia (GA). PATIENTS AND METHODS: We retrospectively reviewed PRC under LACS from 2003 to 2017. We analysed perioperative parameters between patients who successfully underwent PRC under LACS and patients with post-procedural complications or treatment failure (renal mass enhancement after successful intraoperative tumour ablation). Two-sided non-parametric and Fisher's exact tests were performed to compare uncomplicated or disease-free PRC with the complication or treatment failure group, respectively. RESULTS: A total of 100 PRCs under LACS were performed during the study period. Of these patients, six patients had at least one postoperative complication (6%), and treatment failure was diagnosed in nine patients (9%) after PRC [mean (SD) follow-up of 42.7 (26.6) months]. The procedural failure rate was 1%. No ablations were converted to GA. The mean tumour size was smaller in patients who had no complications during PRC compared to those who did, at a mean (SD) of 2.2 (0.6) cm vs 3.0 (1.0) cm (P = 0.039). The use of more intraoperative probes during the PRC was also associated with complications, at a mean (SD) 3.0 (1.4) vs 1.8 (0.8) (P = 0.021). CONCLUSIONS: PRC under LACS is an effective and safe procedural approach for managing small renal masses with low complication, treatment failure, and procedural failure rates. Larger renal masses and intraoperative use of multiple probes is associated with an increased risk of PRC complications. ABBREVIATIONS: BMI: body mass index; CCI: Charlson Comorbidity Index; GA: general anaesthesia; LACS: local anaesthesia and conscious sedation; PRC: percutaneous renal cryoablation; R.E.N.A.L.: Radius, Exophytic/Endophytic, Nearness, Anterior/Posterior, Location.

Implementation of a Dedicated Enhanced Recovery after Surgery (ERAS) Program for Radical Cystectomy Patients is Associated With Decreased Postoperative Inpatient Opioid Usage and Pain Scores.

OBJECTIVE: To measure differences in post-operative opioid usage and pain scores between pre- and post-Enhanced Recovery after Surgery (ERAS) radical cystectomy (RC) patients in an effort to optimize outcomes. STUDY DESIGN: We performed a retrospective cohort study from a single institution from January 1, 2015 to July 31, 2018 among 86 and 108 pre- and post-ERAS RC patients. The primary endpoints were total mean opioid usage (morphine equivalent daily dosing or MEDD) and mean pain scores (Visual Analog Scale) on postoperative days (POD) 1-3. Secondary endpoints were number of opioid pills prescribed at discharge and within 30 days of discharge. Multivariable model selection was carried out with forward selection and backward elimination to identify variables associated with key outcomes. RESULTS: Total mean usage of opioids and mean pain scores were significantly lower in post-ERAS vs pre-ERAS patients across POD 1-3, respectively (32.90 MEDD vs 99.86 MEDD, P ≤ .001; 3.51 vs 4.17, P = .003). The median number of opioid pills prescribed at discharge was significantly lower in the post-ERAS group compared to pre-ERAS (30 pills vs 45 pills, P = .046) as well as the median number opioid pills prescribed within 30 days of discharge (40 pills vs 50 pills, P = .001). CONCLUSION: Our study suggests that a dedicated ERAS protocol following RC might be superior to traditional, non-ERAS methods in reducing postoperative opioid use and pain scores.

Nutritional predictors of complications following radical cystectomy.

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.
