Introduction: The available studies comparing robot-assisted radical cystectomy (RARC) with intracorporeal (ICUD) vs. extracorporeal (ECUD) urinary diversion have not relied on a standardized methodology to report complications and did not assess the effect of different approaches on postoperative outcomes., Materials: Two hundred and sixty seven patients treated with RARC at a single center were assessed. A retrospective analysis of data prospectively collected according to a standardized methodology was performed. Multivariable logistic regression models (MVA) assessed the impact of ICUD vs. ECUD on intraoperative complications, prolonged length of stay (LOS), 30-day Clavien Dindo (CD) ≥ 2 complications and readmission rate. Interaction terms tested the impact of the approach on different patient subgroups. Lowess graphically depicted the probability of CD ≥ 2 after ICUD or ECUD according to patient baseline characteristics., Results: Overall, 162 ICUD vs 105 ECUD (61 vs. 39%) were performed. Intraoperative complications were recorded in 24 patients. The median LOS and readmission rate were 11 vs. 13 (p = 0.02) and 24 vs. 22% (p = 0.7) in ICUD vs. ECUD, respectively. Overall, 227 postoperative complications were recorded. The overall rate of CD ≥ 2 was 35 and 43% in patients with ICUD vs. ECUD, respectively (p = 0.2). At MVA, the approach type was not an independent predictor of any postoperative outcomes (all p ≥ 0.4). Age-adjusted Charlson Comorbidity Index (ACCI) was associated with an increased risk of CD ≥ 2 (OR: 1.2, p = 0.006). We identified a significant interaction term between ACCI and approach type (p = 0.04), where patients with ICUD had lower risk of CD ≥ 2 relative to those with ECUD with increasing ACCI., Conclusions: Relying on a standardized methodology to report complications, we observed that highly comorbid patients who undergo ICUD have lower risk of postoperative complications relative to those patients who received ECUD.

Introduction: Robotic surgical technology has evolved to include a new platform specifically designed for the single-port (SP) approach. Benefits of the da Vinci SP are still under investigation. This study aimed to review the urological literature since the first report of the use of the platform., Evidence Acquisition: We performed a systematic literature review of PubMed, Medline, and Web of Science databases on June 15, 2020 searching for all available articles of da Vinci SP use from December 2014 (date of the first clinical report of da Vinci SP in the urology) until June 1, 2020 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines., Evidence Synthesis: A total of 43 articles were eligible for inclusion. Ten studies reported different surgeries and techniques on cadavers while the rest described the clinical experience of different groups. We divided our article and tables into preclinical experience with surgery on cadavers, radical prostatectomy (RP) approach, and multiple types of procedures described in the same study., Conclusions: The application of da Vinci SP in urologic procedures after five years of the first clinical investigation is feasible and safe. Radical prostatectomy is the most common intervention performed with this robot. Some groups described benefits in terms of less postoperative pain and early discharge, especially with the extraperitoneal approach. However, further studies with larger sample sizes and longer follow-up are awaited.

The aim of this study was to assess whether transversus abdominis plane (TAP) blocks can be utilized to decrease patient pain scores and narcotic use during the first 24 h following robot-assisted laparoscopic prostatectomy (RALP). 100 patients received a TAP block with a mixture of 1.3% liposomal bupivacaine, 0.5% Marcaine and 0.9% NaCl prior to RALP. This was in addition to an already established pain management regiment, which included preoperative PO acetaminophen (650 mg), celecoxib (200 mg), and tolterodine ER (4 mg). These patients were prospectively followed and then retrospectively compared to a 1:1 propensity matched group of 100 patients that did not receive a TAP but did receive the preoperative PO medications. Pain scores were assessed on a scale from 1-10 in the PACU, as well as the surgical floor at 8, 16, and 24-h post-surgery. Intra-/post-operative narcotic use and time to ambulation following arrival to the surgical floor were also analyzed. Patient receiving TAP blocks had immediate post-op pain scores of 2.23 vs 4.26 for those not receiving TAP blocks (p = 0.000). The pain scores at 8, 16, and 24 h for TAP patients were 2.68, 2.62, and 2.62 as compared to 2.89, 2.87, and 3.36 for non-TAP patients. The difference was statistically significant for immediate and 24-h pain scores (p = 0.000, 0.001, respectively). On average, TAP block patients ambulated faster than non-TAP patients, 2.68 vs 4.91 h (p = 0.000). Intra-operative narcotic use was decreased in the TAP group for each of the opioids that were used: fentanyl 177.5 vs 205mcg (p = 0.001), morphine 5.5 vs 10 mg (p = 0.000), and hydromorphone 0.75 vs 1.75 mg (p = 0.001). Narcotic usage in the PACU was limited to hydromorphone and TAP patients used 0.7 mg compared to 1.36 mg (p = 0.003) for non-TAP patients. Oral oxycodone/acetaminophen (5 mg/325 mg) was used for pain control on the surgical floor and on average TAP patients received less, 2.4 vs 5 tabs (p = 0.000). Average time to perform the TAP block was 3.5 min and total OR time for TAP vs non-TAP patients was 107.41 vs 106.58 min (p = 0.386). TAP blocks as part of a perioperative pain management protocol can be utilized during RALPs to decrease patient pain scores at two different time intervals, immediately post-operative and 24 h after surgery. Patients also ambulate sooner following surgery and require a decreased amount of narcotics during the intra-operative and post-operative periods. TAP blocks are quick, effective, and do not add a significant amount of OR time to RALPs.

Objective: To describe the crucial factors related to the implementation of the da Vinci single-port (SP) system (Intuitive Surgical Inc., Sunnyvale, CA, USA), and the early outcomes after the introduction of this robot for robot-assisted radical prostatectomy (RARP)., Patients and Methods: We prospectively collected data from 50 consecutive patients with prostate adenocarcinoma who underwent RARP using this robot. The median follow-up was 53 days. We performed a transperitoneal technique. The robotic (multiport) trocar was placed on the supra-umbilical midline 20 cm from the pubis and an assistant trocar placed in the right lower quadrant. We report our initial experience describing the intra- and postoperative outcomes associated with this new robot. Also, we report the early functional and oncological outcomes in the follow-up period considered. Continuous variables were described as medians and interquartile ranges, while categorical variables as frequencies and proportions., Results: The median total operative time was 118 min, median console time was 80 min, and median estimated blood loss was 50 mL. There were no intraoperative complications or blood transfusions. The final pathology reported 18% Grade Group (GrGp)1, 58% GrGp2, 18% GrGp3, 2% GrGp4, and 4% GrGp5. In all, 40 patients (80%) were pT2 and 20% were ≥pT3a. The overall positive surgical margin rate was 14%. In all, 39 patients (78%) achieved full continence at median of 21 days after RARP. The median pain scale (0-10) score at 8, 12 and 16 h after RARP was 2, 2, and 0, respectively., Conclusion: The use of the da Vinci SP robot with an additional assistant port for RARP is technically safe and feasible, with acceptable short-term functional and oncological outcomes. However, there is a technical learning curve for this new platform due to the smaller scope of the operative field and the decreased flexibility and strength of the surgical instruments., (© 2020 The Authors BJU International © 2020 BJU International Published by John Wiley & Sons Ltd.)

The global meat industry is constantly evolving due to changes in consumer preferences, concerns and lifestyles, as well as monetary, geographical, political, cultural and religious factors. Part of this evolution is the introduction of synthetic antioxidants to increase meat and meat products' shelf-life, and reduce meat spoilage due to lipid and protein oxidation. The public perception that natural compounds are safer and healthier per se has motivated the meat industry to replace synthetic antioxidants with plant-derived ones in meat systems. Despite several promising results from in vitro and in situ studies, the effectiveness of plant-derived antioxidants against lipid and protein oxidation has not been fully documented. Moreover, the utility, usability, marketability and potential health benefits of natural antioxidants are not yet fully proven. The present review aims to (i) describe the major chemical groups of plant-derived antioxidants and their courses of action; (ii) present the application of spices, herbs and fruits as antioxidants in meat systems; and (iii) discuss the legislative framework, future trends, challenges and limitations that are expected to shape their acceptance and mass exploitation by the meat industry.

Background: Early recovery of continence and potency after robotic-assisted laparoscopic prostatectomy (RALP) still remains a challenge., Objective: To assess the effect of our modified apical dissection and lateral prostatic fascia preservation (mod-RALP) technique on early functional outcomes., Design, Setting, and Participants: Among 2168 patients who underwent RALP between 2017 and 2019, 104 received a mod-RALP, and for the purposes of this study they were propensity score (PS) matched with a control group of conventional RALP cases based on preoperative and histological characteristics., Surgical Procedure: In the mod-RALP technique, significant dissection of the apical complex was avoided with maximized preservation of periurethral tissue around the urethral stump. Nerve sparing was also modified with intrafascial dissection inside of the lateral fascia, leaving the lateral tissue including the neurovascular bundle (NVB) untouched and covered., Measurements: The mod-RALP and conventional RALP groups were compared for continence and potency recovery at 1 and 6 wk postoperatively, as well as at 3, 6, and 12 mo. Kaplan-Meier curves and multivariate Cox regression models were used to identify survival estimations and their predictors., Results and Limitations: The mod-RALP technique resulted in faster continence (mean 46 vs 70 d) and potency (mean 74 vs 118 d, p <  0.05 for both) recovery. Functional recovery rates at postoperative follow-up were significantly higher in the mod-RALP group at all time points within the first 6 mo following surgery. Multivariate analyses revealed age, baseline functional status, surgical technique, and lymph node dissection as independent predictors of early functional recovery. This study is limited by its retrospective design and small size of the study groups., Conclusions: Our results with a modified technique intended to better preserve the apical complex and NVBs suggest earlier recovery of urinary continence and sexual function. These results should be tested with future randomized studies., Patient Summary: We report a modified approach to apical dissection and lateral prostatic fascia preservation in robotic-assisted laparoscopic prostatectomy that resulted in earlier continence and potency recovery as compared with our conventional technique., (Copyright © 2020.

Background: Since the implementation of robotic surgery, the platforms have been updating constantly in terms of arm configuration, tool design, scope settings, and the number of trocars placed. The introduction of new robotic technology is challenging and requires studies followed by technique adaptions., Objective: This study aims to report a logical and technologically safe approach to the learning curve using the da Vinci single-port (SP) console and describes our robotic-assisted radical prostatectomy (RARP) technique step by step., Design, Setting, and Participants: A prospective study from 26 consecutive patients who underwent RARP with the da Vinci SP console from June to August 2019., Surgical Procedure: All surgeries were performed with a transperitoneal technique; one robotic trocar was placed above the umbilicus and one additional 12 mm trocar was placed in the right lower quadrant., Measurements: We described the step-by-step technique and reported the perioperative and pathological data. In addition, we considered the hospital length of stay and pain scale following surgery. Continuous variables were reported as median and interquartile ranges. Categorical variables were reported as frequencies and proportions., Result and Limitations: The total median operative time was 121 min, console time was 85 min, and blood loss was 50 ml. No complications were reported. In the final pathology, four patients had Gleason 6, 20 had Gleason 7, one had Gleason 8, and one had Gleason 9.Of the patients, 70% were ≤pT2 and 30% were ≥pT3a. Only 11% had positive surgical margins. This study is limited by the small number of patients and a short period of follow-up to evaluate functional and oncological outcomes of this new technology., Conclusions: RARP with the da Vinci SP is feasible and safe. Therefore, the step-by-step technique described in this study could be considered an option to perform radical prostatectomies. However, we still need better-designed studies to compare the outcomes with those of the multiport platform., Patient Summary: We reported our step-by-step technique describing a safe approach to robotic-assisted radical prostatectomy during the transition from the Xi to the da Vinci single-port robot., (Copyright © 2020.

Pelvic lymph node dissection (pLND) is considered the most reliable method for the detection of lymph node metastases in prostate cancer. Current clinical guidelines recommend performing pLND in intermediate- and high-risk patients that are defined using different clinical nomograms and different cut-off values. Although the detection of lymph node metastatic disease can identify patients who could benefit from adjuvant therapies and potentially improve prostate cancer-related survival outcomes, so far there has been no level 1 evidence to support this survival benefit. Available retrospective data that suggest oncological benefits are subject to various forms of bias. Furthermore, pLND is not feasible or may be risky in some patient-related conditions, such as morbid obesity and previous history of intraabdominal surgery including organ transplants. In this review, we discuss the current controversies surrounding pLND during robotic-assisted prostatectomy in prostate cancer, specifically the pitfalls in interpretation of restricted evidence suggesting its oncological benefits, and examine the potential influence of patient- and surgeon-related factors that may determine the decision to perform pLND.

Pelvic lymph node dissection (PLND) can cause lymphoceles. Lymphocele formation following PLND can reach up to 60% and are symptomatic in 0.4 to 16% of patients. The aim of the study was to identify factors that are significantly associated with lymphocele drainage. We retrospectively analysed all men that underwent RALP between April 2010 and November 2018 from our prospectively collected IRB approved database. All patients who developed lymphoceles were grouped into two groups, the ones who were drained and those not drained. Chi-square test was used to perform univariate analysis for categorical variables and student's t test for continuous variables. Odds ratio was calculated using logistic multiple regression analysis. A P value of less than 0.05 was considered significant. The size of the lymphocele, the number of nodes retrieved, and BMI were significant factors that led to the drainage of lymphocele. The patients with lymphoceles larger than 10 cm had an odds ratio of 47.5 and those between 5 and 10 had an odds ratio of 10.7. The odds ratio of drainage in patients with BMI above 30 was 2.1. The odds of drainage were 8.8 when more than 10 nodes were taken. After PLND ultrasound could be effective in early identification of patients who could potentially need drainage. Early elective drainage should be offered to patients who have more than 10 lymph nodes removed with a lymphocele size more than 10 cm in size and BMI above 30.

Objectives: To compare salvage robot-assisted laparoscopic prostatectomy (RALP) outcomes in patients who underwent radiation and those who underwent focal ablation as primary therapies., Patients and Methods: We evaluated 126 patients who underwent salvage RALPbetween 2008 and 2018. Of these, 94 (74.6%) received radiation and 32 focal ablation (25.4%) as primary therapy. These groups were compared with regard to clinical, oncological and functional outcomes. Kaplan-Meier curves and regression models were used to identify survival estimations and their predictors., Results: Before surgery, more patients were potent in the focal ablation group compared to the radiation group (46.9% vs 22.6%; P = 0.013). Peri-operative characteristics and complication rates were not significantly different between the two groups. Postoperative catheterization duration was shorter in the focal ablation group (mean 10 vs 16 days; P = 0.018). At final pathology, the focal ablation group had higher non-organ-confined disease (71% vs 50%; P = 0.042) and positive surgical margin (PSM) rates (43.8% vs 17%; P = 0.004) as compared to the radiation group; however, 5-year biochemical recurrence (BCR)-free survival rates were similar (59% vs 56%; P = 0.761). Postoperative 1-year full (no pads/day) and social (0-1 pad/day) continence rates were significantly higher in the focal ablation as compared to the radiation group (77.3% vs 39.2%, P = 0.002, and 87.5% vs 51.3%, P = 0.002, respectively). Multivariate analyses showed primary focal ablation and nerve-sparing to be predictors of postoperative continence. Erectile function was preserved in 13% and 27% of preoperatively potent patients in the radiation and focal ablation groups, respectively (P = 0.435). No predictors were identified for postoperative potency., Conclusions: Radiation was associated with inferior functional outcomes after salvage RALP. Focal therapies were associated with higher non-organ-confined disease and PSMrates, with no significant difference in short-term BCR-free survival., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)
