Predictive factors for pentafecta achievement in robot-assisted partial nephrectomy for intermediate highly complex RENAL tumors (RENAL score ≥ 7).

OBJECTIVES: To investigate the predictive factors for pentafecta achievement of robot-assisted partial nephrectomy (RAPN) for intermediate highly complex renal tumors (RENAL score ≥ 7). METHODS: We retrospectively analyzed the data of 247 patients with renal tumors with a RENAL score ≥ 7 who underwent RAPN. Baseline characteristics and perioperative outcomes were compared between the pentafecta achieved group and the unachieved group. A multivariable logistic regression model was used to identify the predictive factors for pentafecta achievement for cT1 renal tumors with a RENAL score ≥ 7. RESULTS: Of the 247 patients, 75 (30.3%) patients were in the achieved group and 172 (69.7%) patients were in the unachieved group. The median warm ischemia time and total operation time were 18 min versus 23 min (p < 0.001) and 179 min versus 201 min (p < 0.001) in the achieved and unachieved groups, respectively. In the unachieved group, six patients (3.4%) had major perioperative complications (Clavien-Dindo classification system ≥3). The median preservation rates of estimated GFR at the 1-year postoperative period were 96.5% versus 83.0% (p < 0.001) in the achieved and unachieved groups. Multivariable logistic regression models revealed that age and tumor size were independent predictive factors for pentafecta achievement for cT1 renal tumors with a RENAL score ≥ 7. There were no significant differences in cancer-free survival between the two groups (p = 0.456). CONCLUSION: Age and tumor size were independent predictive factors for pentafecta achievement, although there was no difference in oncological outcomes between the pentafecta achieved group and the unachieved group in RAPN for cT1 renal tumors with a RENAL score ≥ 7.

External validation of Pentafecta in patients undergoing laparoscopic radical cystectomy: results from a high-volume center.

BACKGROUND: To investigate whether Pentafecta is suitable for bladder cancer patients receiving laparoscopic radical cystectomy (LRC). METHODS: From November 2013 to December 2020, muscle invasive Bladder Cancer (MIBC) and non-muscle invasive Bladder Cancer (NMIBC) patients who received LRC and urinary diversion were retrospectively analyzed. Pentafecta was defined as meeting five criteria: negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year. Analyze the achievement of five criteria and compare the overall survival (OS) of Pentafecta group with non-attainment group. Multivariable Cox's regression was performed to evaluate the impact of Pentafecta on OS. Multivariable logistic regression was performed to explore the effect of surgical experience on Pentafecta attainment. RESULTS: A total of 340 patients were included, negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year were observed in 95.3%, 30.3%, 83.8%, 75.0% and 85.6% of patients, respectively. Pentafecta group had a significantly longer OS than the non-attainment group (P = 0.027). The group with 10-15 LNs removed and meeting the other four criteria had a similar OS to group with ≥ 16 LNs removed (Pentafecta group) (5-year OS: 67.3% vs 72.7%, P = 0.861). Pentafecta (HR = 0.33, P = 0.011), positive lymph nodes (HR = 2.08, P = 0.028) and MIBC (HR = 3.70, P < 0.001) were all significant predictors of OS in multivariable Cox's regression. Surgical experience (OR = 1.05, P < 0.001), conduit (OR = 2.09, P = 0.047) and neobladder (OR = 2.47, P = 0.048) were all independent predictors of Pentafecta attainment in multivariable logistic regression. CONCLUSIONS: Pentafecta is suitable for bladder cancer patients receiving LRC and has the potential to be a valuable tool for evaluating the quality of LRC. Based on Pentafecta analysis, removing 10 LNs instead of 16 LNs as the one of the five criteria may be more appropriate for bladder cancer patients.

Trends in risk-group distribution and Pentafecta outcomes in patients treated with nerve-sparing, robot-assisted radical prostatectomy: a 10-year low-intermediate volume single-center experience.

PURPOSE: To evaluate the trends in risk-group distribution and Pentafecta outcomes in patients treated with nerve-sparing (NS), robot-assisted radical prostatectomy (RARP) in a single low-intermediate volume prostate cancer (PCa) center over a 10-year period. MATERIALS AND METHODS: We queried a prospectively maintained database for patients who underwent NS RARP between 2009 and 2018 in a low-intermediate volume PCa center. Risk-groups were defined according to the D'Amico classification. Pentafecta outcomes referred to the postsurgical presence of potency and continence, and the absence of biochemical recurrence (BCR), positive surgical margins (PSM), and perioperative complications. The Kruskall-Wallis test, the t test and the Mann-Whitney tests were used when appropriate. RESULTS: 603 patients underwent NS RARP and 484 patients were evaluated for Pentafecta outcomes. Median postsurgical follow-up was 28 months. Overall, 137 (22.7%), 376 (62.3%), and 90 (15%) patients were diagnosed in the low-, intermediate-, and high-risk groups, respectively. Patients undergoing NS RARP shifted from 33 to 20% in the low-risk group, from 52 to 62% in the intermediate-risk group, and from 10 to 13% in the high-risk group. Patients reaching Pentafecta increased from 38 to 44%. No postoperative potency was the main reason for non-achieving Pentafecta (71%). BCR strongly limited Pentafecta achievement in the high-risk group (61%), but not in intermediate (24%) and low-risk (30%) groups. CONCLUSIONS: Low-intermediate volume PCa centers show similar trends to high-volume centers regarding risk group distributions over time in PCa patients undergoing NS RARP. We reported an increase in Pentafecta outcomes achievement over time even for experienced surgeons. Pentafecta outcomes achievement is risk-group dependent.

Radical cystectomy pentafecta: a proposal for standardisation of outcomes reporting following robot-assisted radical cystectomy.

OBJECTIVE: To propose a standardisable composite method for reporting outcomes of radical cystectomy (RC) that incorporates both perioperative morbidity and oncological adequacy. PATIENTS AND METHODS: From July 2010 to December 2017, 277 consecutive patients who underwent robot-assisted RC with intracorporeal urinary diversion (UD) for bladder cancer at our Institution were prospectively analysed. Patients who simultaneously demonstrated negative soft tissue surgical margins (STSMs), ≥16 lymph node (LN) yield, absence of major (grade III-IV) complications at 90 days, absence of UD-related long-term sequelae and absence of clinical recurrence at ≤12 months, were considered as having achieved the RC-pentafecta. A multivariable logistic regression model was assessed to measure predictors for achieving RC-pentafecta. RESULTS AND LIMITATIONS: Since 2010, 270 of 277 patients that had completed at least 12 months of follow-up were included. Over a mean follow-up of 22.3 months, ≥16 LN yield, negative STSMs, absence of major complications at 90 days, and absence of UD-related surgical sequelae and clinical recurrence at ≤12 months were observed in 93.0%, 98.9%, 76.7%, 81.5% and 92.2%, patients, respectively, resulting in a RC-pentafecta rate of 53.3%. Multivariable logistic regression analysis revealed age (odds ratio [OR] 0.95; P = 0.002), type of UD (OR 2.19; P = 0.01) and pN stage (OR 0.48; P = 0.03) as independent predictors for achieving RC-pentafecta. CONCLUSIONS: We present a RC-pentafecta as a standardisable composite endpoint that incorporates perioperative morbidity and oncological adequacy as a potential tool to assess quality of RC. This tool may be useful for assessing the learning curve and calculating cost-effectiveness amongst others but needs to be externally validated in future studies.

External validation of the Simplified PADUA REnal (SPARE) nephrometry system in predicting surgical outcomes after partial nephrectomy.

BACKGROUND: Pentafecta is a major goal in the era of partial nephrectomy (PN). Simplified PADUA REnal (SPARE) nephrometry system was developed to evaluate the complexity of tumor. However, the predictive ability in pentafecta of SPARE system is yet to be determined. The aim of this study was to externally validate the applicability of SPARE nephrometry system in predicting pentafecta achievement after partial nephrectomy, and to examine inter-observer concordance. METHODS: We retrospectively reviewed data of 207 consecutive patients who underwent PN between January 2012 and August 2018 at a tertiary referral center. We obtained SPARE, R.E.N.A.L., and PADUA scores and evaluated correlations among the nephrometries and surgical outcomes including pentafecta by Spearman test. Logistic regression analysis was used to identify independent predictors of pentafecta outcomes. We compared the nephrometries to determine the predictive ability of achieving pentafecta using receiver operating characteristic curve analysis. Fleiss' generalized kappa was used to assessed interobserver variation in the SPARE system. RESULTS: Based on the SPARE system, 120, 74, and 13 patients were stratified into low-risk, intermediate-risk, and high-risk groups, respectively. Regarding the individual components of pentafecta, there were significant differences in the complication rate (p = 0.03), ischemia time (p < 0.001), and percent change of eGFR (p < 0.001) among the three risk groups. In addition, higher tumor complexity was significantly associated with a lower achievement rate of pentafecta (p = 0.01). In Spearman correlation tests, SPARE nephrometry was correlated with ischemia time (ρ:0.37, p < 0.001), operative time (ρ:0.28, p < 0.001), complication rate (ρ:0.34, p < 0.001), percent change of eGFR (ρ:0.34, p < 0.001), and progression of chronic kidney disease stage (ρ:0.17, p = 0.02). Multivariate analysis revealed that SPARE significantly affected pentafecta (OR: 0.67, p < 0.001). In ROC curve analysis, SPARE showed fair predictive ability in the achievement pentafecta (AUC: 0.71). The predictive ability of pentafecta was similar between nephrometries (SPARE vs. R.E.N.A.L., p = 0.78; SPARE vs. PADUA, p = 0.66). The interobserver concordance of SPARE was excellent (Kappa: 0.82, p = 0.03). CONCLUSIONS: SPARE system was a predictive factor of surgical outcomes after PN. This refined nephrometry had similar predictive abilities for pentafecta achievement compared with R.E.N.A.L. and PADUA.

Comparison of retroperitoneal and transperitoneal robotic partial nephrectomy for Pentafecta perioperative and renal functional outcomes.

BACKGROUND: We compared quality outcomes between transperitoneal (TRPN) and retroperitoneal robotic partial nephrectomy (RRPN). METHODS: Two-center retrospective analysis of TRPN and RRPN from 10/2009 to 10/2015. Perioperative/renal function outcomes were analyzed. Primary endpoint was Pentafecta, a composite measure of quality [negative margin, no 30-day complication, ischemia time ≤25 min, return of glomerular filtration rate (eGFR) to >90% from baseline at last follow-up, and no chronic kidney disease upstaging]. Multivariable analysis (MVA) for factors associated with lack of optimal outcome was performed. RESULTS: 404 patients (TRPN 263, RRPN 141) were analyzed. Comparing TRPN vs. RRPN, mean tumor size (3.1 vs. 2.9 cm, p = 0.122) and RENAL score (7.4 vs. 7.2, p = 0.503) were similar. Most TRPN were anterior (65.0%) and most RRPN posterior (65.3%, p < 0.001). Operative time (p = 0.001) was less for RRPN. No significant differences between TRPN vs. RRPN were noted for ischemia time (23.1 vs. 22.8 min, p = 0.313), blood loss (p = 0.772), positive margins (p = 0.590), complications (p = 0.537), length of stay (p = 0.296), ΔeGFR (p = 0.246), eGFR recovery to >90% (55.9 vs. 57.4%, p = 0.833), and lack of CKD upstaging (84.0 vs. 87.2%, p = 0.464). Pentafecta rates were not significantly different (TRPN 33.9 vs. RRPN 43.3%, p = 0.526). MVA revealed increasing RENAL score (OR 1.5, p < 0.001) and decreasing baseline eGFR (OR 2.4, p = 0.017) as predictive for lack of Pentafecta. CONCLUSIONS: TRPN and RRPN have similar quality outcomes, though RRPN may offer modest benefit for operative time and have utility in posterior tumors. Association of increasing RENAL score and decreased baseline eGFR with lack of Pentafecta suggests dominant role of non-modifiable factors.

Optimizing outcome reporting after radical cystectomy for organ-confined urothelial carcinoma of the bladder using oncological trifecta and pentafecta.

UNLABELLED: Radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) is associated with heterogeneous functional and oncological outcomes. The aim of this study was to generate trifecta and pentafecta criteria to optimize outcome reporting after RC. METHODS: We interviewed 50 experts to consider a virtual group of patients (age ≤ 75 years, ASA score ≤ 3) undergoing RC for a cT2 UCB and a final histology of ≤pT3pN0M0. A ranking was generated for the three and five criteria with the highest sum score. The criteria were applied to the Prospective Multicenter Radical Cystectomy Series 2011. Multivariable binary logistic regression analyses were used to evaluate the impact of clinical and histopathological parameters on meeting the top selected criteria. RESULTS: The criteria with the highest sum score were negative soft tissue surgical margin, lymph node (LN) dissection of at least 16 LNs, no complications according to Clavien-Dindo grade 3-5 within 90 days after RC, treatment-free time between TUR-BT with detection of muscle-invasive UCB and RC <3 months and the absence of local UCB-recurrence in the pelvis ≤12 months. The first three criteria formed trifecta, and all five criteria pentafecta. A total of 334 patients qualified for final analysis, whereas 35.3 and 29 % met trifecta and pentafecta criteria, respectively. Multivariable analyses showed that the relative probability of meeting trifecta and pentafecta decreases with higher age (3.2 %, p = 0.043 and 3.3 %, p = 0.042) per year, respectively. CONCLUSIONS: Trifecta and pentafecta incorporate essential criteria in terms of outcome reporting and might be considered for the improvement of standardized quality assessment after RC for UCB.

Impact of chronic kidney disease stages on surgical and functional outcomes in robot-assisted partial nephrectomy for localized renal tumors.

The influence of chronic kidney disease stage on robot-assisted partial nephrectomy outcomes remains underexplored. This study aimed to assess the impact of chronic kidney disease stage on functional and surgical outcomes of robot-assisted partial nephrectomy and identify preoperative predictors of significant postoperative 1-year renal-function loss (RFL). Clinical data of 408 patients who underwent robot-assisted partial nephrectomy at Yokohama City University Hospital between 2016 and 2023 were retrospectively reviewed. The da Vinci Surgical System was applied in all patients, and outcomes assessed included surgical parameters, postoperative estimated glomerular filtration rate, trifecta and pentafecta achievements, and complications. Significant RFL was defined as estimated glomerular filtration rate reduction ≥ 25% from baseline. Higher chronic kidney disease stages correlated with older age, hypertension, diabetes, and solitary kidneys. Postoperative estimated glomerular filtration rate decline was most pronounced in patients with chronic kidney disease stages 4-5. Although the chronic kidney disease stage did not significantly affect most surgical parameters, pentafecta achievement was higher in patients with chronic kidney disease stage 3 than in those with stages 4-5. Two patients required hemodialysis after robot-assisted partial nephrectomy. Multivariable logistic regression analysis showed that preoperative hemoglobin level and maximum tumor diameter were significant predictive factors for significant RFL. In conclusion, preoperative CKD stage did not influence on surgical outcome except for pentafecta achievement. RAPN may be feasible for patients with CKD stages 4-5 because of no rapid progression to hemodialysis induction and no procedure-related mortality. Preoperative hemoglobin levels and tumor diameter emerged as predictors of significant RFL.

Assessing pentafecta outcomes post radical cystectomy: A tertiary care center study.

INTRODUCTION: Bladder cancer is a common and serious disease globally, often requiring radical cystectomy as the preferred treatment. However, this procedure carries substantial risks and complications. To evaluate its success, pentafecta, a five-component measure, was introduced. This study investigates the attainment of pentafecta following radical cystectomy and examines factors that influence its achievement. METHODOLOGY: This retrospective, single-group study was conducted at AIIMS Jodhpur. The study population included 42 patients who underwent radical cystectomy for bladder cancer. Various data, including demographic characteristics, clinical features, surgical techniques, and postoperative outcomes, were collected from medical records. The primary outcome measure was the rate of achieving pentafecta, which comprises five parameters. RESULTS: Out of 42 patients, 26 (61.9%) achieved pentafecta. Age, gender, comorbidities and surgical approach did not significantly affect the attainment of pentafecta. Negative surgical margins were achieved in 95.2% of cases, and adequate lymph node dissection (>16 lymph nodes) was performed in 85.7% of cases. The absence of Clavien-Dindo grade 3-5 complications and recurrence was observed in 80.9% and 90.47% of cases, respectively. Uretero-enteric stricture was absent in 95.2% of cases. CONCLUSION: The study emphasizes the significance of negative surgical margins, thorough lymph node dissection, absence of complications, recurrence, and uretero-enteric strictures in evaluating the success of radical cystectomy as pentafacta outcomes. Patients with higher drain output and wound infections are less likely to achieve pentafacta outcome and indicates poorer outcome. By considering these factors, clinicians can assess patient outcomes and identify areas for improvement.

Comparison of Trifecta and Pentafecta Outcomes across 3 Surgical Modalities of Partial Nephrectomy (PN) - Open, Lap, and Robotic.

Renal cell carcinoma (RCC) is the most common solid tumor in the kidney (90%), accounting for about 3% of all cancers in adults. Partial nephrectomy (PN) is the surgical procedure primarily used for the treatment of localized kidney tumors. Two commonly used terms to describe the complexity and success of a partial nephrectomy procedure are "trifecta" and "pentafecta." Trifecta is defined as Warm ischemia time (WIT) ≤ 25min or Cold ischemia time (CIT) ≤ 60min, Negative surgical margin (NSM), and no perioperative Clavien-Dindo complications (CDC) of Gr 3 or more [8], whereas pentafecta is defined as trifecta plus >90% preservation of e-Glomerular filtration rate (GFR) and no increase in chronic kidney disease (CKD) stage at 12-months post-operative period. We retrospectively analyzed all patients who underwent partial nephrectomy at a single high-volume tertiary centre, from 2012 to 2020. We included patients who underwent partial nephrectomy by any of the three routes including open (OPN), laparoscopic (LPN), or robotic-assisted (RPN), and in which the follow-up data was available. We compared the trifecta and pentafecta outcomes across the three surgical modalities. We had a total of 183 patients in our study. Twenty-nine percent (53 patients) underwent open surgery, 12.6% (23 patients) underwent laparoscopic surgery and 58.5% (107) underwent robotic assisted surgery. The number of patients who fell under the low risk category in the RENAL scoring system were 70(38.3%), intermediate risk 79 (43.2%) and high risk 34 (18.6%). In the high risk RENAL score group, trifecta was achieved in 5 (50%) patients in OPN, 1(50%) in LPN and 7(31.8%) in RPN with no statistically significant difference (p = 0.581) whereas pentafecta was achieved in 3 (30%) patients in OPN, 1 (50%) in LPN and 7 (31.8%) in RPN with no statistically significant difference (0.855). In the overall cohort, mean WIT, mean hospital stay and mean EBL were higher in OPN as compared to LPN and RPN which was statistically significant (p < 0.001), whereas there was no statistical difference in mean operative time between the three modalities (p = 0.580). Renal tumors can be safely treated by RPN or LPN with lesser morbidity as compared to OPN. Trifecta and Pentafecta outcomes had no significant difference among OPN, LPN, and RPN. RPN and LPN may be considered feasible and safe surgical approaches ensuring good functional outcomes.

Impacts of Complete Endophytic Renal Tumors on Surgical, Functional, and Oncological Outcomes of Robot-Assisted Partial Nephrectomy.

Objective: Complete endophytic renal tumors (CERTs) are the most challenging for robot-assisted partial nephrectomy (RAPN). This study aimed to determine the impact of CERT on outcomes of RAPN. Methods: All RAPN cases for localized renal tumor undertaken at Yokohama City University Hospital between 2016 and 2023 were enrolled. Tumor characteristics and surgical, functional, and oncologic outcomes of RAPN were compared between CERT and non-CERT groups. Results: Consecutive 666 patients were enrolled, and 76 (11.4%) were identified as CERT (3 points of "E" score). CERT showed smaller tumor diameters (p < 0.001), more predominant hilar tumor (p = 0.029), higher "N" scores (p < 0.001) and "L" scores (p = 0.006) than non-CERT. The CERT group showed longer warm ischemia times (p < 0.001), more frequent positive surgical margins (p = 0.028), and relatively lower trifecta achievement rates (p = 0.101) than the non-CERT group. In multivariable analysis, the CERT was an independent predictor for trifecta achievement but not for pentafecta achievement. Conclusions: CERT was associated with longer warm ischemia time, positive surgical margin, and lower trifecta achievement, but not with surgical complication and pentafecta achievement in RAPN. This study suggested that CERT had limited influence on long-term renal functional preservation; however, it had strong impacts on short-term surgical outcome.

The current role of pentafecta in the reporting of radical cystectomy outcomes: a scoping review.

Background: Pentafecta has recently been validated for reporting radical cystectomy (RC) outcomes in open, laparoscopic and robotic series. We aim in this review to explore the current role of pentafecta in the reporting of RC outcomes. Methods: A comprehensive literature search was performed in the PubMed database to identify relevant articles. The pentafecta achievement (PA) was defined originally as negative soft tissue surgical margin (NSTSM), lymph node (LN) dissection (LND) with removal of ≥16 LNs, absence of 90-days grade ≥3 Clavien-Dindo (CD) complications, a time interval of less than 3 months between the last transurethral resection of bladder tumor (TURBT) with evidence of muscle invasive bladder cancer (MIBC) and RC, and absence of local pelvic recurrence within 1 year. The definition was later modified and the last two criteria were replaced by absence of urinary diversion (UD) related complications and any clinical recurrence at one year. Results: Twelve studies with 4,946 patients were enrolled in the present review. All the studies were retrospective except one recently published randomized study comparing open and robotic-assisted RC. Pentafecta was totally achieved in 34% and main causes of missing pentafecta were the number of resected LNs and 90-days major complications. Type of UD, increasing age, advanced tumor stage, and decreasing surgical experience were the factors most commonly associated with a lower likelihood of PA. A positive correlation was seen between PA and long-term oncological outcome and quality of life. The main limitations in the present studies are their retrospective nature, relatively small sample size, and short median follow-up, most of which was less than 3 years. Conclusions: The new pentafecta definition provides a comprehensive tool for reporting RC outcomes by including measures of postoperative morbidity, functional outcomes and local cancer control. Pentafecta include standards that could be useful for improving surgical quality, surgical education and comparing different techniques. However, pentafecta is not yet suitable for perioperative risk stratification and patient counseling.

Assessment of the Impact of Pentafecta Parameters Affecting the Quality of Life of Patients Undergoing Laparoscopic Radical Prostatectomy.

Prostate cancer is being detected in increasingly younger men. These patients expect to preserve their current quality of life and quickly recover after treatment. Medical technology and surgical techniques are advancing along with the growing expectations of patients. In addition, the universal method of assessing the quality of outcomes after operations is constantly being researched. As of today, biochemical remission alone, after radical prostatectomy, is insufficient for the patient. Therefore, multi-parametric evaluation methods are being developed, such as trifecta, which assesses biochemical remission, continence, and erectile function. The improvement over the trifecta is the pentafecta, which additionally evaluates postoperative complications and infiltration of surgical margins. Our study was conducted within a group of patients who were surgically treated for prostate cancer in 2017 at the Clinic of Urology and Urological Oncology of the Pomeranian Medical University. We recruited 237 men for the study. From that group, 131 men met the criteria to be included in the analysis. Maintaining continence (87.78%) is the easiest pentafecta parameter to obtain and will have the greatest impact on quality of life in the future. Maintaining biochemical remission (82.44%) is the second most important aspect for the patient. Retaining erectile function is the most difficult pentafecta parameter to obtain (29.01%) while having little impact on the quality of life. Negative surgical margins (66.41%) showed a negligible impact on the quality of life. The occurrence of complications (32.07%) has a negative impact on the quality of life of patients, but only during the treatment of complications.

Technologic advances in robot-assisted nephron sparing surgery: a narrative review.

Background and Objective: Nephron sparing surgery (NSS) is the preferred management for clinical stage T1 (cT1) renal masses. In recent years, indications have expanded to larger and more complex renal tumors. In an effort to provide optimal patient outcomes, urologists strive to achieve the pentafecta when performing partial nephrectomy. This has led to the continuous technologic advancement and technique refinement including the use of augmented reality, ultrasound techniques, changes in surgical approach and reconstruction, uses of novel fluorescence marker guided imaging, and implementation of early recovery after surgery (ERAS) protocols. The aim of this narrative review is to provide an overview of the recent advances in pre-, intra-, and post-operative management and approaches to managing patients with renal masses undergoing NSS. Methods: We performed a non-systematic literature search of PubMed and MEDLINE for the most relevant articles pertaining to the outlined topics from 2010 to 2022 without limitation on study design. We included only full-text English articles published in peer-reviewed journals. Key Content and Findings: Partial nephrectomy is currently prioritized for cT1a renal masses; however, indications have been expanding due to a greater understanding of anatomy and technologic advances. Recent studies have demonstrated that improvements in imaging techniques utilizing cross-sectional imaging with three-dimensional (3D) reconstruction, use of color doppler intraoperative ultrasound, and newer studies emerging using contrast enhanced ultrasound play important roles in certain subsets of patients. While indocyanine green administration is commonly used, novel fluorescence-guided imaging including folate receptor-targeting fluorescence molecules are being investigated to better delineate tumor-parenchyma margins. Augmented reality has a developing role in patient and surgical trainee education. While pre-and intra-operative imaging have shown to be promising, near infrared guided segmental and sub-segmental vessel clamping has yet to show significant benefit in patient outcomes. Studies regarding reconstructive techniques and replacement of reconstruction with sealing agents have a promising future. Finally, ERAS protocols have allowed earlier discharge of patients without increasing complications while improving cost burden. Conclusions: Advances in NSS have ranged from pre-operative imaging techniques to ERAS protocols Further prospective investigations are required to determine the impact of novel imaging, in-vivo fluorescence biomarker use, and reconstructive techniques on achieving the pentafecta of NSS.

Pentafecta for Radical Nephroureterectomy in Patients with High-Risk Upper Tract Urothelial Carcinoma: A Proposal for Standardization of Quality Care Metrics.

Background: Measuring quality of care indicators is important for clinicians and decision making in health care to improve patient outcomes. Objective: The primary objective was to identify quality of care indicators for patients with upper tract urothelial carcinoma (UTUC) and to validate these in an international cohort treated with radical nephroureterectomy (RNU). The secondary objective was to assess the factors associated with failure to validate the pentafecta. Design: We performed a retrospective multicenter study of patients treated with RNU for EAU high-risk (HR) UTUC. Outcome measurements and statistical analysis: Five quality indicators were consensually approved, including a negative surgical margin, a complete bladder-cuff resection, the absence of hematological complications, the absence of major complications, and the absence of a 12-month postoperative recurrence. After multiple imputations and propensity-score matching, log-rank tests and a Cox regression were used to assess the survival outcomes. Logistic regression analyses assessed predictors for pentafecta failure. Results: Among the 1718 included patients, 844 (49%) achieved the pentafecta. The median follow-up was 31 months. Patients who achieved the pentafecta had superior 5-year overall- (OS) and cancer-specific survival (CSS) compared to those who did not (68.7 vs. 50.1% and 79.8 vs. 62.7%, respectively, all p < 0.001). On multivariable analyses, achieving the pentafecta was associated with improved recurrence-free survival (RFS), CSS, and OS. No preoperative clinical factors predicted a failure to validate the pentafecta. Conclusions: Establishing quality indicators for UTUC may help define prognosis and improve patient care. We propose a pentafecta quality criteria in RNU patients. Approximately half of the patients evaluated herein reached this endpoint, which in turn was independently associated with survival outcomes. Extended validation is needed.

Reaching Consensus for Comprehensive Outcome Measurement After Urethral Stricture Surgery: Development of Study Protocol for Stricture-Fecta Criteria.

Urethral stricture disease is a very heterogeneous condition where different urethral segments can be involved as a result of diverse etiologies which come with variable prognosis. The surgical management of urethral strictures, and in particular urethroplasties can result in very diverse outcomes on many levels and, currently, there is absolutely no consensus about what should and what should not be considered a "success" after urethral surgery. In the wake of well-established quality criteria in urologic oncology, such as tri- or pentafecta outcomes, and given the lack of agreement on meaningful outcomes after urethral surgery, we aim to introduce our study protocol as the first step of a multistep research endeavor to reach consensus on comprehensive urethroplasty outcomes within a novel conceptual framework: the "stricture-fecta criteria". The development of stricture-fecta will be based on a Delphi consensus involving some of worldwide most influencing reconstructive urologists.

The learning curve for robot-assisted radical cystectomy with total intracorporeal urinary diversion based on radical cystectomy pentafecta.

Objective: To analyze the learning curve for robot- assisted radical cystectomy (RARC) with total intracorporeal urinary diversion (ICUD) in terms of both time efficiency and quality of surgery based on radical cystectomy (RC)-pentafecta. Patients and methods: We identified 203 consecutive patients who underwent RARC with ICUD of the ileal conduit (IC, 85) and orthotopic neobladder (ONB, 118) performed by a single surgeon between 2011 and 2021. We grouped ten consecutive patients into time-associated blocks according to the operation order. Process efficiency and operation quality were measured based on the surgeon's console time and attainment/score sum of RC-pentafecta. The overcoming point of the learning curve was defined graphically and statistically. Results: The mean follow-up period was 44.5 ± 30.7 months. Of the 203 patients, 109 (53.7%) attained the five criteria of RC-pentafecta (ONB vs IC, 50.6% vs. 55.9%, p = 0.35). The attainment rate and sum of the RC-pentafecta score of the third group were not significantly different from those of all patients (40.0% vs. 53.7%, p = 0.369, 4.00 ± 1.05 vs. 4.41 ± 0.75, p = 0.137, respectively), and the proficiency in operation quality was satisfactory in the third group. The console times continually improved and stabilized after the 140th case (IC, 60; ONB, 80), and the attainment rate and sum of the RC-pentafecta were significantly different between before and after the 140th case (p<0.001). Conclusion: A single surgeon's learning curve for RARC with ICUD and pelvic lymph node dissection (PLND) showed an acceptable level of proficiency after 30 consecutive cases in terms of the operation quality. However, for an expert surgeon, 140 cases were required to reach a plateau in time efficiency and second leap with the RC-pentafecta. RARC with ICUD and PLND can be performed safely without compromising functional outcomes and complications through sharing and transmission of standardized techniques.

Oncological and functional results after robot-assisted radical prostatectomy in high-risk prostate cancer patients.

BACKGROUND: Pentafecta is currently the standard in the comprehensive evaluation of patients undergoing radical prostatectomy, the objective of this study is the evaluation of oncological and functional outcomes in patients with prostate cancer of high risk undergoing robot-assisted radical prostatectomy. METHOD: Descriptive, retrospective study of 20 cases with a diagnosis of high-risk prostate cancer. The high-risk group is composed of a prostate-specific antigen equal or greater than 20 ng/mL, Gleason score equal or greater than 8, or clinical stages T2/T3 treated with robotic approach. RESULTS: Biochemical control was achieved from the first six weeks after the surgical event. 75% (n = 15) had negative surgical margins. 100% of the patients (n = 20) presented urinary continence immediately after removal of the urinary catheter. Erectile function was preserved at 3, 6 and 12 months in 100% of the patients who underwent neuropreservation but with use of an PDE inhibitor. (n = 5). Complications were reported in 10% (Clavien-Dindo I-II). CONCLUSIONS: Robot-assisted radical prostatectomy in patients with high-risk prostate cancer is considered an appropriate treatment option in selected patients. A different experimental design is needed to define the advantages or disadvantages of this approach, as well as to determine its role and application in clinical practice.

ANTECEDENTES: Pentafecta es el estándar en la evaluación integral de los pacientes sometidos a prostatectomía radical. El objetivo de este estudio es evaluar y describir los desenlaces oncológicos y funcionales en pacientes con cáncer de próstata de alto riesgo sometidos a prostatectomía radical asistida por robot. MÉTODO: Estudio descriptivo, retrospectivo, de 20 pacientes con diagnóstico de cáncer de próstata de alto riesgo. El grupo de alto riesgo se compone por pacientes con antígeno prostático específico mayo o igual a 20 ng/ml, reporte histopatológico con Gleason mayor o igual a 8 y/o estadios clínicos T2/T3 tratados con abordaje robótico. RESULTADOS: El control bioquímico se alcanzó a partir de las primeras 6 semanas posterior al evento quirúrgico. El 75% (n = 15) presentaron márgenes quirúrgicos negativos. El 100% de los pacientes (n = 20) presentaron continencia urinaria inmediatamente después del retiro de la sonda vesical. La función eréctil se conservó a 3, 6 y 12 meses en el 100% de los pacientes a los que se realizó neuropreservación, pero con uso de inhibidor de la fosfodiesterasa (n = 5). Se reportaron complicaciones en el 10% de los casos (Clavien-Dindo I-II). CONCLUSIONES: La prostatectomía radical asistida por robot en pacientes con cáncer de próstata de alto riesgo se considera una opción de tratamiento adecuada en casos seleccionados. Se necesita un diseño experimental distinto para definir las ventajas o desventajas de este abordaje, así como determinar su papel y aplicación en la práctica clínica.
