Abstract
This article is an English translation of the Clinical Practice Guidelines for Upper Tract Urothelial Carcinoma (2nd edition) published in June 2023. The Japanese Urological Association's (JUA) Guidelines Committee on Upper Tract Urothelial Carcinoma (UTUC) created a 2023 update guideline to support clinicians' current evidence-based management of UTUC and to incorporate its recommendations into clinical practice. The new guideline adhered as closely as possible to the Minds Manual for Guideline Development 2020 ver. 3.0. Findings related to epidemiological, pathological, diagnosis, treatment, and follow-up were reviewed. In addition, seven clinical questions (CQs) were set to determine the grade of recommendation and level of evidence. Preconceptions and biases were removed from the preparation process, the overall evidence was evaluated appropriately, and recommendations were made after fully considering the balance between benefits and harms. Although the evidence is still insufficient to be taken up as a CQ, the latest important information is described in seven columns, and clinical issues that should be resolved in the future related to the CQ are described as recommendations for tomorrow. We hope that these guidelines will help medical professionals, patients, and their families involved in the treatment of UTUC in their decision-making, and hope that a critical review of these guidelines will lead to further refinements in the next edition.

Abstract
PURPOSE OF REVIEW This narrative review aims to evaluate the role of lymph node dissection (LND) in upper tract urothelial carcinoma (UTUC) and its implications for staging and management outcomes, as well as future perspectives. RECENT FINDINGS Multiple studies have demonstrated the limitations of conventional imaging techniques in accurately localizing lymph node metastasis (LNM) in UTUC. While 18F-fluorodeoxyglucose positron emission tomography with computed tomography (18FDG-PET/CT) shows promise for preoperative LNM detection, its specificity is low. Alternative methods such as choline PET/CT and sentinel lymph node detection are under consideration but require further investigation. Additionally, various preoperative factors associated with LNM hold potential for predicting nodal involvement, thereby improving nodal staging and oncologic outcomes of LND. Several surgical approaches, including segmental ureterectomy and robot-assisted nephroureterectomy, provide a possibility for LND, while minimizing morbidity. LND remains the primary nodal staging tool for UTUC, but its therapeutic benefit is still uncertain. Advances in imaging techniques and preoperative risk assessment show promise in improving LNM detection. Further research and multi-center studies are needed to comprehensively assess the advantages and limitations of LND in UTUC, as well as the long-term outcomes of alternative staging and treatment strategies.

Oncological Efficacy of Robotic Nephroureterectomy vs. Open and Laparoscopic Nephroureterectomy for Suspected Non-Metastatic UTUC-A Systematic Review and Meta-Analysis. Cancers (Basel) 2023; 15:4926. [PMID: 37894293 PMCID: PMC10605607 DOI: 10.3390/cancers15204926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 09/28/2023] [Accepted: 10/02/2023] [Indexed: 10/29/2023] Open
Abstract
INTRODUCTION AND AIMS The optimal approach for nephroureterectomy in patients with suspected UTUC remains a point of debate. In this review, we compare the oncological outcomes of robotic nephroureterectomy (RNU) with open (ONU) or laparoscopic nephroureterectomy (LNU). METHODS All randomized trials and observational studies comparing RNU with ONU and/or LNU for suspected non-metastatic UTUC are included in this review. The systematic review was performed in accordance with the Cochrane Guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The primary outcome measures were overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), and intravesical recurrence-free survival (IV-RFS). The secondary outcome measures were the lymph node dissection (LND) rates, positive margin rates, and the proportion of patients receiving bladder intravesical chemotherapy. RESULTS We identified 8172 references through our electronic searches and 8 studies through manual searching. A total of 15 studies met the inclusion criteria. The total number of patients in the review was 18,964. RNU had superior OS compared to LNU (HR: 0.81 (95% CI: 0.71, 0.93), p-0.002 (very low certainty)). RNU and ONU had similar OS (HR: 0.83 (95% CI: 0.52, 1.34), p-0.44 (very low certainty)). One study reported an independent association of RNU as a worse predictor of IV-RFS when compared to ONU (HR-1.73 (95% CI: 1.22, 2.45)). The LND rates were higher in the RNU cohort when compared to the LNU cohort (RR 1.24 (95% CI: 1.03, 1.51), p-0.03 (low certainty)). The positive margin rate was lower in the RNU cohort when compared to the ONU cohort (RR 0.29 (95% CI: 0.08, 0.86), p-0.03 (low certainty)). CONCLUSION RNU offers comparable oncological efficacy to ONU, except for intravesical recurrence-free survival (IV-RFS). RNU has fewer positive surgical margin rates compared to ONU in well-balanced studies. RNU appears to outperform LNU for certain oncological parameters, such as OS and the proportion of patients who receive lymph node dissections. The quality of evidence comparing surgical techniques for UTUC has remained poor in the last decade.

First Comparison of Retroperitoneal Versus Transperitoneal Robot-Assisted Nephroureterectomy with Bladder Cuff: A Single Center Study. Ann Surg Oncol 2023:10.1245/s10434-023-13363-0. [PMID: 37099087 DOI: 10.1245/s10434-023-13363-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 02/27/2023] [Indexed: 04/27/2023]
Abstract
INTRODUCTION After recent presentation of the first complete robot-assisted retroperitoneal nephroureterectomy with bladder cuff (RRNU) for patients with upper tract urothelial cancer (UTUC), we aimed to compare this new surgical technique with robot-assisted transperitoneal nephroureterectomy (TRNU) representing the current standard of care. METHODS Robot-assisted nephroureterectomies (NUs) were retrospectively analyzed and compared based on two groups: transperitoneal versus retroperitoneal approach. Baseline data were collected for patient demographics, tumor characteristics, intra- (EAUiaiC) and postoperative (Clavien-Dindo) complications, and perioperative variables. Tumor characteristics included grade of malignancy, clinical stage, and surgical margin status. Short-term follow-up data including 30-day readmission rates were collected. Statistical analyses were performed assuming a significant p-value of < 0.05. RESULTS The analysis includes perioperative patient data after proven UTUC of 24 TRNU versus 12 RRNU (mean age: 70 versus 71 years; BMI: 25.9 versus 26.1 kg/m2; CCI score ≥ 4: 83% versus 75%; ASA score ≥ 3: 37% vs 33%). Intraoperative (16.4% vs 0%, p = 0.35) and postoperative (25% vs 12.5%, p = 0.64) complications demonstrated no significant discrepancy. Notably, RRNU demonstrated significantly shorter surgery time (p < 0.05) and length of stay (p < 0.05). There was no significant difference in histopathological tumor characteristics, whereas significantly more lymph nodes were removed through RRNU (11.0±3.3 vs. 6.4±5.1, p < 0.05). Finally, no statistical difference was shown in short-term follow-up. CONCLUSION We report the first head-to-head comparison between RRNU and TRNU. RRNU proves to be a safe and feasible approach which appears to be non-inferior to TRNU. RRNU expands the spectrum of minimally invasive treatment options, particularly for patients with major previous abdominal surgery.

Abstract
BACKGROUND For medical institutions without robotic equipment, it remains uncertain whether laparoscopic radical nephroureterectomy (LNU) can achieve results similar to those of robotic surgery for the treatment of upper tract urothelial carcinoma (UTUC). This meta-analysis aimed to compare the efficacy and safety of robot-assisted radical nephroureterectomy (RANU) with that of LNU using a large sample size of patients. METHODS A systematic meta-analysis was performed using data (available to May 2022) acquired from multiple scientific databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines, according to the protocols registered with PROSPERO (CRD42021264046), were followed to perform this cumulative analysis. RESULTS Nine high-quality studies were included in this analysis, considering factors such as operative time (OT), estimated blood loss (EBL), length of hospital stay (LOS), positive surgical margins (PSM), and complications. Statistical indicators revealed no significant differences between the RANU and LNU groups in terms of OT (weighted mean difference [WMD] 29.41, 95% confidence interval [CI] -1.10 to 59.92; p = 0.22), EBL (WMD -55.30, 95% CI -171.14 to 60.54; p = 0.13), LOS (WMD -0.39, 95% CI -1.03 to 0.25; p = 0.12), PSM (odds ratio [OR] 1.22, 95% CI 0.44-3.36; p = 0.17], or complications (OR 0.91, 95% CI 0.49-1.69; p = 0.13). CONCLUSION The meta-analysis showed that the perioperative and safety indicators of both RANU and LNU were similar and both showed favorable outcomes in UTUC treatment. However, some uncertainties remain in the implementation and selection of lymph nodes for dissection.

Abstract
Background Upper tract urothelial carcinoma (UTUC) is the malignant transformation of urothelial cells, from the renal calyces to the ureteral orifices. While the benefits of minimally invasive nephroureterectomy over their open counterpart have been established, the optimal technique remains a debate. We aimed to assess current evidence in the literature and compare outcomes between robotic-assisted (RANU) and laparoscopic nephroureterectomy (LNU). Methods A systematic review of the literature was performed for studies comparing RANU and LNU for bladder cancer. Outcome measurements were recurrence rates (local and distal), positive margins, positive lymph node yield and perioperative outcomes. Meta-analysis was performed using Review Manager 5. Results Our results demonstrate a significantly higher mortality rate in patients undergoing laparoscopic nephroureterectomy when compared with the robotic-assisted approach for the treatment of UTUC (1.8% vs. 1.1%, p = 0.008); however, these results were inconsistent on sensitivity analysis and should therefore be interpreted with caution. No significant difference was observed for other outcomes. Conclusion The ideal approach to minimally invasive radical nephroureterectomy remains undetermined. Future research, ideally prospective randomised studies, should focus on long-term outcomes, in particular recurrence, recurrence-free survival, overall survival and the correlation between surgical technique and survival.

Abstract
Background Robot-assisted nephroureterectomy (RANU) and laparoscopic nephroureterectomy (LNU) are two minimally invasive surgical management for upper urinary tract urothelial carcinomas (UTUC). Though more high-tech, it remains largely unclear whether RANU provides additional benefits over LNU. We aimed to quantitatively compare the perioperative and oncologic outcomes between RANU and LNU. Methods The systematic review was performed based on a registered protocol (registration number CRD42022319086). We searched through PubMed, EMBASE and Cochrane databases, as well as conference proceedings and references of review articles (May 2022) for comparative studies reporting perioperative and oncologic outcomes independently in RANU and LNU groups. Selection of studies and data extraction were performed independently by two researchers. Risk of bias was assessed using the modified Newcastle-Ottawa Scale. Results of random-effects meta-analyses were presented as mean differences (MD) or Odds ratio (OR), as appropriate. Subgroup and univariate meta-regression analyses were performed to identify interstudy heterogeneities. Results The review included 8470 patients undergoing RANU and 19872 patients undergoing LNU from 12 comparative original studies. RANU was associated with fewer overall complications (OR=0.71, 95%CI: 0.62 to 0.81), longer operative time (MD=27.70, 95%CI: 0.83 to 54.60) and shorter length of stay (MD=-0.53, 95%CI: -0.98 to -0.07) compared to LNU. In addition, patients receiving RANU were more likely to have lymph node dissected (OR=2.61, 95%CI: 1.86 to 3.65). Recurrence and survival outcomes did not differ between two surgical procedures. Sample size, types of LNU and world region were major sources of heterogeneity. Conclusion For UTUC patients, RANU offers fewer complications and shorter hospitalization. However, RANU requires longer operative time and shares similar oncologic outcomes compared to LNU. Further randomized designed studies are warranted.

Abstract
Upper-tract urothelial carcinoma is a relatively rare malignancy. Current guidelines strongly recommend radical nephroureterectomy with bladder cuff excision and template-based lymph node dissection for all high-risk upper-tract urothelial carcinomas. Although the open approach is still considered the standard of care, evolution of minimally invasive approaches especially the robotic-assisted approach, has been found to be oncologically equivalent. Since its initial description in 2006, the surgical technique as well as the robotic surgical system has gone through a major evolution. With well-established advantages of the minimally invasive approach, robotic radical nephroureterectomy also has the ability to address both upper and lower urinary tract simultaneously without the need of patient repositioning, standardized single docking technique, ease of performing crucial steps like excision of ureterovesical junction and bladder cuff with watertight cystotomy closure, allowing perioperative instillation of intra-vesical chemotherapy. Robot-assisted radical nephro-ureterectomy and template-based lymph node dissection is gradually emerging as the current standard of care to achieve the best possible oncologic and functional outcomes. In this review article we are focusing on the evolution of this approach in the management of upper-tract urothelial carcinoma along with a review of oncologic outcomes.

Initial Experience of Robot-Assisted Laparoscopic Nephroureterectomy in Japan: A Useful Technique Using a Vessel Sealing Device for Securing a Good Surgical Field and Efficient Sealing. Asian J Endosc Surg 2022; 15:458-462. [PMID: 34877806 DOI: 10.1111/ases.13017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 10/27/2021] [Accepted: 11/23/2021] [Indexed: 01/23/2023]
Abstract
INTRODUCTION Although robot-assisted nephroureterectomy (RANU) has been increasingly used worldwide, the history of RANU remains short, and the optimal surgical method for performing RANU has yet to be established. Here we introduce the ideal approach for RANU using the Vessel Sealer Extend (VSE). MATERIALS AND SURGICAL TECHNIQUE RANU was performed by using a da Vinci Xi surgical system with fenestrated bipolar forceps (by the left arm), and monopolar scissors or needle drivers (by the right arm), and the VSE (by the third arm). First, nephrectomy and lymphadenectomy were performed at the kidney direction stage, followed by the removal of the distal ureter and suturing of the bladder at the bladder direction stage. The key point of our technique is that the console surgeon can continue to obtain the optimal surgical field by traction using the third arm, and thus cut the tissue by smoothly switching between the right hand and the third arm without the need to exchange instruments, especially in the kidney direction stage. In this study we performed RANU in nine patients and lymphadenectomy in seven patients. The median console time was 195 (range: 165-265) min, the median blood loss was 55 (range: 5-179) ml. In eight cases of RANU using the VSE, no lymphatic leakage was observed and all procedures could be performed safely. DISCUSSION The use of VSE provides sufficient coagulation and optimal surgical field development, thus allowing console surgeons to perform RANU more safely.

Pentafecta for Radical Nephroureterectomy in Patients with High-Risk Upper Tract Urothelial Carcinoma: A Proposal for Standardization of Quality Care Metrics. Cancers (Basel) 2022; 14:cancers14071781. [PMID: 35406553 PMCID: PMC8997024 DOI: 10.3390/cancers14071781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 03/21/2022] [Accepted: 03/22/2022] [Indexed: 12/04/2022] Open
Abstract
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.

Abstract
Introduction and importance Case presentation Clinical discussion Conclusion Symptomatic patients presenting upper urinary tract urothelial carcinoma benefit from surgery, a minimal invasive approach being preferable. Nephroureterectomy with lymphnode metastasis poses surgical challenges in order to achieve negative resection margins and optimal lymphadenectomy. A combined 3D laparoscopic and Da Vinci X robotic surgical approach offered improved operatory time and better management of intra-pelvic disease. An optimal surgical strategy respects the surgical experience of the main surgeon combined with access to minimal invasive technology. The gentle and precise movements of the Da Vinci robot allowed an accurate dissection with en bloc specimen excision and optimal lymphadenectomy, presenting possible implications in staging and oncologic outcomes.

Abstract
PURPOSE To compare the outcomes of robotic radical nephroureterectomy (RRNU) and laparoscopic radical nephroureterectomy (LRNU) within a large multi-institutional worldwide dataset. MATERIAL AND METHODS The ROBotic surgery for Upper tract Urothelial cancer STudy (ROBUUST) includes data from 17 centers worldwide regarding 877 RRNU and LRNU performed between 2015 and 2019. Baseline features, perioperative and oncological outcomes, were included. A 2:1 nearest-neighbor propensity-score matching with a 0.001 caliper was performed. An univariable and a multivariable logistic regression model were built to evaluate the predictors of a composite "tetrafecta" outcome defined as occurrence of bladder cuff excision + LND + no complications + negative surgical margins. RESULTS After matching, 185 RRNU and 91 LRNU were assessed. Patients in the RRNU group were more likely to undergo bladder cuff excision (81.9% vs 63.7%; p<0.001) compared to the LRNU group. A statistically significant difference was found in terms of overall postoperative complications (p=0.003) and length of stay (p<0.001) in favor of RRNU. Multivariable analysis demonstrated that LRNU was an independent predictor negatively associated with achievement of "tetrafecta" (OR: 0.09; p=0.003). CONCLUSIONS In general, RRNU and LRNU offer comparable outcomes. While the rate of overall complications is higher for LRNU in this study population, this is mostly related to low grade complications, and therefore with more limited clinical relevance. RRNU seems to offer shorter hospital stay but this might also be related to the different geographical location of participating centers. Overall, the implementation of robotics might facilitate achievement of a "tetrafecta" outcome as defined in the present study.

Abstract
Purpose: Discordance between pre-operative biopsy and final pathology for Upper Tract Urothelial Carcinoma (UTUC) is high and optimal management remains controversial. The aim of this study is to evaluate the accuracy of pre-operative biopsy, to identify prognostic factors and to evaluate the effect of adjuvant chemotherapy on survival and oncologic outcome in UTUC. Methods: We analyzed records of patients receiving surgical treatment for UTUC. Pathology of pre-operative biopsy was compared to surgical specimen. We used Kaplan-Meier method to estimate survival probabilities and Cox's proportional hazards models to estimate the association between covariates and event times. Primary endpoint was overall survival (OS). A matched-pair analysis was performed to evaluate the effect of adjuvant chemotherapy. Results: 151 patients underwent surgical treatment (28% open, 36% laparoscopic, 17% robotic radical nephroureterectomy; 14% segmental ureteral resections and 5% palliative nephrectomy) for UTUC and were included in the analysis. Upstaging from <pT1 in endoscopic biopsy to ≥pT1 in final pathology occurred in 61% of patients and upgrading from low-grade to high-grade occurred in 30% of patients. Five-year OS was 59.5%. In the univariate Cox-regression model pathological stage, grade, lymphovascular invasion and positive surgical margins were associated with OS. Matched pair analysis for stage (<pT3; ≥pT3; pN+) and age revealed a significant survival benefit for adjuvant chemotherapy (HR 0.40, 0.14-0.77, p < 0.018) in this cohort. Conclusion: UTUC is often underestimated in pre-operative biopsy, and it is associated with significant mortality. Pathological stage and grade, lymphovascular invasion and lymph node metastases are predictors of oncologic outcome and survival.

Abstract
This case-based discussion describes the management of a 66-yr-old man who presented to the emergency department with gross hematuria. His urine cytology was benign, and computed tomography (CT) with nephrographic phase revealed a 2.5 cm filling defect within the left renal pelvis and luminal narrowing in the right proximal ureter with hydronephrosis. CT showed no lymphadenopathy and no sign of metastatic disease. Cystoscopy was normal. In a progressive case-based discussion fashion, we will discuss the diagnostic and treatment options with two different perspectives: (1) guidelines-based current standard of care and (2) an outlook on future perspectives using the latest scientific advances that may soon become the standard of care. PATIENT SUMMARY: This presentation of a real-life clinical scenario will be useful in describing the current standard of care and future perspectives regarding the diagnosis and treatment of upper urinary tract tumors.
