Standard management for recurrent low-grade non-muscle-invasive bladder cancer (LG-NMIBC) often involves a substantial treatment burden, which is not justified by the relatively indolent course of the disease, prompting a need for de-intensification strategies. Active surveillance (AS) is an alternative approach aimed at reducing overtreatment in selected patients. However, the broader adoption of AS is hindered by a lack of standardized protocols for patient selection, monitoring and intervention. To address this gap, we conducted an international, two-round Delphi consensus among 51 bladder cancer experts to establish foundational statements for the use of AS. Consensus was achieved on 20 statements, providing clear recommendations for terminology; inclusion and exclusion criteria; follow-up monitoring; and exit criteria. This Delphi consensus provides the first expert-driven framework to standardize the clinical application of AS for LG-NMIBC. These statements could guide current clinical practice and unify the design of future trials.

Background: Chronic pelvic pain (CPP) associated with pudendal neuralgia (PN) significantly impacts quality of life (QoL). Pudendal nerve infiltration is a recognized treatment, but the optimal timing of intervention remains unclear. Methods: This prospective study included 81 patients diagnosed with PN and treated with pudendal nerve infiltrations. Outcomes were assessed using the Visual Analog Scale (VAS), Spanish Pain Questionnaire (CDE–McGill), and the SF-12 health survey. Significant improvement was defined as a VAS reduction > 4 points and a QoL increase > 15 points. An ROC curve analysis identified a 13-month time-to-treatment threshold (sensitivity 78%, specificity 72%), categorizing patients into early (n = 27) and delayed treatment groups (n = 54). Results: The early treatment group showed significantly greater reductions in VAS scores (5.4 vs. 3.4 points, p < 0.01) and QoL improvements (18 vs. 8 points, p < 0.01) compared to the delayed group. Early intervention reduced reinfiltration rates (10% vs. 35%, p < 0.05) and decreased medication use, with 81% discontinuing gabapentin compared to 41% in the delayed group. Similar trends were observed for tryptizol (44% vs. 35%) and tramadol (74% vs. 30%). Multivariate analysis confirmed time to treatment as the strongest predictor of outcomes, with each additional month delaying treatment associated with a 0.18-point increase in final VAS scores (p < 0.001). Delayed treatment was linked to higher final doses of gabapentin (p = 0.01), dexketoprofen (p < 0.001), and tramadol (p = 0.012). Minimal complications were reported (15%, Clavien I). Conclusions: Early intervention in PN significantly improves pain, QoL, and reduces reinfiltration and medication reliance, supporting timely treatment for optimal outcomes.

Background and objective There is no standardized regimen for follow-up after radical cystectomy (RC) for bladder cancer (BC). To address this gap, we conducted a multicenter study involving urologist members from the European Association of Urology (EAU) bladder cancer guideline panels. Our objective was to identify consistent post-RC follow-up strategies and develop a practice-based framework based on expert opinion. Methods We surveyed 27 urologist members of the EAU guideline panels for non–muscle-invasive bladder cancer and muscle-invasive and metastatic bladder cancer using a pre-tested questionnaire with dichotomous responses. The survey inquired about follow-up strategies after RC and the use of risk-adapted strategies. Consistency was defined as >75% affirmative responses for follow-up practices commencing 3 mo after RC. Descriptive statistics were used for analysis. Key findings and limitations We received responses from 96% of the panel members, who provided data from 21 European hospitals. Risk-adapted follow-up is used in 53% of hospitals, with uniform criteria for high-risk (at least ≥pT3 or pN+) and low-risk ([y]pT0/a/1N0) cases. In the absence of agreement for risk-based follow up, a non-risk-adapted framework for follow-up was developed. Higher conformity was observed within the initial 3 yr, followed by a decline in subsequent follow-up. Follow-up was most frequent during the first year, including patient assessments, physical examinations, and laboratory tests. Computed tomography of the chest and abdomen/pelvis was the most common imaging modality, initially at least biannually, and then annually from years 2 to 5. There was a lack of consistency for continuing follow-up beyond 10 yr after RC. Conclusions and clinical implications This practice-based post-RC follow-up framework developed by EAU bladder cancer experts may serve as a valuable guide for urologists in the absence of prospective randomized studies. Patient summary We asked urologists from the EAU bladder cancer guideline panels about their patient follow-up after surgical removal of the bladder for bladder cancer. We found that although urologists have varying approaches, there are also common follow-up practices across the panel. We created a practical follow-up framework that could be useful for urologists in their day-to-day practice.

BACKGROUND AND OBJECTIVE:Ureteral stents are used to protect the ureteroenteric anastomosis during radical cystectomy and urinary diversion (RCUD); however, complications can occur from its use. The objective of this study was to perform a systematic review of perioperative stenting strategies and postoperative outcomes in patients undergoing RCUD for bladder cancer. METHODS:This review was published via PROSPERO (CRD42024558468) and conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Medline, Medline In-Process, Embase, and the Cochrane Central Register of Controlled Trials were searched. Prospective comparative (randomised and nonrandomised) studies published until June 2024 were included. All outcomes were included in the analysis. Risk of bias assessments were undertaken. KEY FINDINGS AND LIMITATIONS:The search yielded 1516 abstracts. Six prospective comparative studies (740 patients) were included. Although there was some evidence of reduced postoperative complications (urinary leak, ureteroileal stricture, postoperative obstruction, length of stay, and readmission within 30 d) with the omission of stents during RCUD, this did not reach statistical significance (n = 3). No differences in postoperative complications were identified between internal and external stenting (n = 2). Early stent removal (5 d) was associated with reduced urinary tract infections and hospital readmission (n = 1). There was a high/serious risk of bias with all studies. CONCLUSIONS AND CLINICAL IMPLICATIONS:The role of perioperative stenting during RCUD in preventing ureteroenteric complications remains equivocal and does not favour one approach over another. Until further results from on-going randomised controlled trials become available, urologists should carefully consider the indications to place a ureteric stent and its retention time after RCUD.

Bladder cancer is the ninth most common cancer globally, with most cases classified as non-muscle-invasive bladder cancer (NMIBC). While transurethral resection of the bladder tumor (TURBT) remains the gold-standard treatment, its complications, high recurrence rates, and economic burden have prompted interest in alternative strategies like active surveillance (AS) for low-grade and low-grade NMBIC recurrences. AS minimizes surgical interventions and patient burden, but lacks standardized protocols for inclusion criteria and follow-up schedules. Most studies suggest intensive monitoring during the first year, with criteria often based on tumor size, number, and grade. Acquisition of evidence: A comprehensive literature search was conducted in December 2024 using Pubmed, Cochrane, and Trip databases to identify studies on AS for low-grade NMBIC recurrences. Only English studies were included, with Boolean operators used to refine the search. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Population, Intervention, Comparison and Outcomes (PICO) selection criteria were followed. The Newcastle–Ottawa quality assessment scale was used to analyze the quality of the included studies. Evidence synthesis: This systematic review included 11 studies evaluating AS for NMIBC. Early studies, such demonstrated AS as a feasible alternative to TURBT, with low progression rates. Subsequent research confirmed its safety in selected patients, with tumor growth and positive cytology being the main reasons for intervention. More recent investigations, further supported AS as a viable strategy, highlighting the low risk of stage and grade progression and its potential to reduce surgical interventions. Conclusions: AS may be considered an alternative approach for low-risk NMIBC recurrences. However, there is need for prospective studies and personalized approaches to optimize AS, addressing follow-up strategies, inclusion criteria and progression thresholds.

BACKGROUND AND OBJECTIVE:This publication represents a summary of the updated 2025 European Association of Urology (EAU) guidelines for muscle-invasive and metastatic bladder cancer (MMIBC). The aim is to provide practical recommendations on the clinical management of MMIBC with a focus on diagnosis, treatment, and follow-up. METHODS:For the 2025 guidelines, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences. KEY FINDINGS AND LIMITATIONS:The key recommendations emphasise the importance of thorough diagnosis, treatment, and follow-up for patients with MMIBC. The guidelines stress the importance of a multidisciplinary approach to the treatment of MMIBC patients and the importance of shared decision-making with patients. The key changes in the 2025 muscle-invasive bladder cancer (MIBC) guidelines include the following: a new recommendation for the use of susceptible FGFR3 alterations to select patients with unresectable or metastatic urothelial carcinoma for treatment with erdafitinib; significant adaption and update of the recommendations for pre- and postoperative radiotherapy and sexual organ-preserving techniques in women; new recommendation related to radical cystectomy and extent of lymph node dissection based on the results of the SWOG trial; recommendation related to hospital volume; new recommendations for salvage cystectomy after trimodality therapy and for the management of all patients who are candidates for trimodality bladder-preserving treatment in a multidisciplinary team setting using a shared decision-making process; significant adaption and update to the recommendation for adjuvant nivolumab in selected patients with pT3/4 and/or pN+ disease not eligible for, or who declined, adjuvant cisplatin-based chemotherapy; and addition of a new recommendation for metastatic disease regarding the antibody-drug conjugate trastuzumab deruxtecan in case of HER2 overexpression; in addition, removal of the recommendations on sacituzumab govitecan as the manufacturer has withdrawn the US Food and Drug Administration approval for this product; update of the follow-up of MIBC; and full update of the management algorithms of MIBC. CONCLUSIONS AND CLINICAL IMPLICATIONS:This overview of the 2025 EAU guidelines offers valuable insights into risk factors, diagnosis, classification, treatment, and follow-up of MIBC patients and is designed for effective integration into clinical practice.

Open ureteroenteric reimplantation (OUER) of ureteroenteric strictures (UESs) is related to important morbidity. Robot-assisted ureteroenteric reimplantation (RUER) has been proposed to provide similar outcomes with lower morbidity. We aimed to compare perioperative and functional outcomes between RUER and OUER. A retrospective multicenter study of 80 patients, who underwent 82 ureteroenteric reimplantations (17 OUER vs 65 RUER) at 8 institutions between 2009–2021 for benign UESs after radical cystectomy. All the open procedures were performed by the same center in order to compare the robotic approach with a standardized technique. Data were reviewed for demographics, stricture characteristics, and perioperative outcomes. Complication and stricture recurrence rates were compared between both groups. Among 82 reimplantations, 44 were left sided (54

Currently, there are no reliable prognostic factors to determine which upper tract urothelial carcinoma (UTUC) patients will progress after radical nephroureterectomy (RNU). We aim to evaluate whether liquid-biopsy-based biomarkers (circulating tumor cells (CTCs), cell-free DNA (cfDNA), and circulating tumor DNA (ctDNA)) were able to predict clinical outcomes in localized UTUC patients undergoing RNU. Twenty patients were prospectively enrolled between 2021 and 2023. Two blood samples were collected before RNU and three months later. CTCs and cfDNA were isolated and evaluated using the IsoFlux system and Quant-iT PicoGreen dsDNA kit, respectively. Droplet digital PCR was performed to determine ctDNA status. Cox regression analysis was performed on CTCs, cfDNA, and ctDNA at two different follow-up time points to examine their influence on tumor progression and cancer-specific survival (CSS). During a median follow-up of 18 months, seven (35%) patients progressed and three (15%) died. Multivariate analysis demonstrated that cfDNA levels three months after RNU are a significant predictor of tumor progression (HR = 1.085; p = 0.006) and CSS (HR = 1.168; p = 0.029). No associations were found between CTC enumeration and ctDNA status with any of the clinical outcomes evaluated. The evaluation of cfDNA levels in clinical practice could improve the disease management of UTUC patients.

XBM was prospectively assessed in spontaneous urine collected just before flexible cystoscopy and washing cytology carried out within the first 2 years follow-up of 337 patients with NMIBC. Recurrences were pathologically confirmed in 49 patients (14.5%), 22 of them being high-risk (6.5%). The XBM sensitivity for detecting any type of recurrence was 69.4% and 63.6% in the cases of high-risk NMIBC. Negative predictive value (NPV) for XBM was 93% for all recurrences and 96.2% for high-risk recurrences. XBM could have avoided 213 invasive controls but missed the detection of 15 recurrences (30.6%)-8 of them of high-risk (36.4%). XBM false positive elevations were detected in 90 patients (26.7%), whereas 10 patients with the invasive method had a false positive result (3%), p <0.001. However, early detection of recurrences during the first year's follow-up after an XBM false positive result was observed in 18 patients (20%). On the other hand, 19 recurrences were detected during this period among the rest of the patients (7.7%)-p = 0.003, and odds ratio (OR) 3.0 (95% CI 1.5-6.0). Regarding one-year follow-up recurrences, 10% were high-risk recurrences in the XBM false positive group and 3.2% in the rest of the patients-p = 0.021, and OR 3.3 (95% CI 1.2-8.9). Additionally, 11.3% of the patients without false positive results developed a recurrence, p = 0.897, for any recurrence, being 10% and 5.2%, respectively, and high-risk and low-risk recurrences, p = 0.506. After searching for the best XBM cutoff for detecting the 38 high-risk initial recurrences and the early high-risk recurrences after a one-year follow-up, a linear discriminant analysis (LDA) of 0.13 could have avoided 11.3% of cystoscopies and bladder wash cytologies, as this cutoff missed only 1 high-risk recurrence (2.6%). More extensive and well-designed studies will confirm if XBM can improve the surveillance of NMIBC.

Introduction: Robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is a technically difficult procedure. Our aim was to evaluate the potential impact of the learning curve (LC) on perioperative and pathological outcomes of RARC with ICUD. Material and methods: Retrospective study of 62 consecutive patients who underwent RARC with ICUD for bladder cancer between 2015-2020. We compared 3 consecutive groups of 20 (G1), 20 (G2), and 22 (G3) patients to analyze the impact of the LC. G1 cases were performed by a senior surgeon experienced in robotic surgery, while G2-G3 were performed by 2 junior surgeons without experience under the mentorship of the senior surgeon. Results: The 3 groups had similar clinical and pathological characteristics. A total of 15 patients (24%) received a neobtadder and 47 (75%) an ileal conduit. The mean operative time decreased 60 minutes between G1-G3 (P= 0.001). No conversions to open approach or intraoperative complications were reported. There were no differences between groups regarding positive margin rates (P=0.6) or the number of lymph nodes removed (P=0.061). The postoperative complication rate was 77% and did not change during the LC (P= 0.49). Uretero-enteric stricture rate decreased from 25% in G1 to 9% in G3 (P=0.217). Conclusions: The inclusion of junior surgeons to a RARC with ICUD program after the initial 20 cases does not have an impact on the perioperative and pathological outcomes of the procedure. The operative time and the uretero-enteric stricture rate could be reduced during the LC. (C) 2021 AEU. Published by Elsevier Espana, S.L.U. All rights reserved.

Background & Objectives: We aimed to evaluate the risk of progression in high-grade T1 (HGT1) tumors using tumor budding (TB) and other standard clinical and histological features. TB is defined as an isolated cancer cell or a cluster composed of fewer than 5 cells scattered in the stroma and is usually used as a strong predictor of lymph node metastasis in T1 colorectal cancer. Methods: This is an observational longitudinal cohort study involving 168 consecutive patients with HGT1 between 2013 and 2016. Cox regression was performed to analyze the relationship between the clinical and histological features and progression. All slides were blindly assessed by 2 genitourinary pathologists. Budding was determined to be positive when the number of buds was equal to or greater than 6. Results: The median age was 75 years; 152 (90.5%) patients were men, and 49 (29.2%) were positive for TB. At a median follow-up time of 35 months, 33 patients (19.6%) showed progression. Progression was observed in 32.7% of the patients positive for TB and in only 14.3% of those who were negative (p = 0.006). TB was significantly associated with the endoscopic tumor pattern (TP) (papillary/solid) and lymphovascular invasion (LVI). Univariate analysis showed that TB, carcinoma in situ (CIS), TP, LVI, sub-staging, and BCG induction predict progression. The multivariate analysis showed that TB (p = 0.032, hazard ratio 2.1), CIS, TP, and lack of BCG induction were significant for progression. Conclusions: TB is a new and significant pathological variable for predicting progression in HGT1 tumors and can be easily introduced in clinical practice. Its inclusion in the TNM system should be carefully considered, as it may aid early cystectomy decisions.

INTRODUCTION Bladder cancer is thefifth most common tumor in the world. Moreover, it isone of the most expensive due to its high recurrencerate. Urinary biomarkers for surveillance of non muscleinvasive bladder cancer is a promising and growingfield due to the invasiveness of the actual methods, basedon cystoscopy and cytology. Although current EuropeanGuidelines only consider the use of biomarkersin the low risk scenario as an alternative to cystoscopywhen the patient declines invasive methods for the follow-up after surgery, there is increasing evidence oftheir safety in high risk tumors. MATERIAL AND METHODS We have performeda review of the main urinary biomarkers, includingFDA-approved ones, protein-based and genetic biomarkers.We have also described the different options to incorporatethe biomarkers in the clinical practice. RESULTS There are not randomized control trialscomparing any biomarker with the gold standard follow-up. Most of the papers published so far are cohortstudies, limitating the evidence of the results. Biomarkerscan be used as an alternative of cystoscopy, in a noninvasive follow-up, or alternating both tests. There arefew economical studies comparing both options, but theevidence supports the efficiency of the main biomarkers. CONCLUSIONS Cystoscopy and cytology are the goldstandard for non muscle invasive bladder cancer surveillance.2021 European Guidelines suggest, for the firsttime, an alternative use of biomarkers in a concrete lowgrade scenario to avoid invasive explorations to patientswith low risk of progression. Paradoxically, biomarkers(mainly genetic ones) have a very good profile of sensitivityand negative predictive value in the high risk scenario.Although there is increasing evidence to supporttheir implementation, the lack of fase IV trials hinderstheir daily use.

Background: Open revision of ureteroenteric strictures (UESs) is associated with considerable morbidity. There is a lack of data evaluating the feasibility of robotic revisions.Objective: To analyze the perioperative and functional outcomes of robot-assisted ureteroenteric reimplantation (RUER) for the management of UESs after radical cystectomy (RC).Design, setting, and participants: A retrospective multicenter study of 61 patients, who underwent 63 RUERs at seven high-volume institutions between 2009 and 2020 for benign UESs after RC, was conducted.Outcome measurements and statistical analysis: Data were reviewed for demographics, stricture characteristics, and perioperative outcomes. Variables associated with being stricture free after an RUER were evaluated using a multivariate Cox regression analysis.Results and limitations: Among 63 RUERs, 22 were right sided (35%), 34 left sided (54%), and seven bilateral (11%). Twenty-seven (44%) had prior abdominal/pelvic surgery and five (8%) radiotherapy (RT). Thirty-two patients had American Society of Anesthesiologists (ASA) scores I-II (52%) and 29 ASA III (48%). Fortytwo (68%) RUERs were in ileal conduits, 18 (29%) in neobladders, and two (3%) in Indiana pouch. The median time to diagnosis of a UES from cystectomy was 5 (3-11) mo. Of the UESs, 28 (44%) failed an endourological attempt (balloon dilata-tion/endoureterotomy). The median RUER operative time was 195 (175-269) min. No intraoperative complications or conversions to open approach were reported. Twenty-three (37%) patients had postoperative complications (20 [32%] were minor and three [5%] major). The median length of hospital stay was 3 (1-6) d and readmissions were 5%. After a median follow-up of 19 (8-43) mo, 84% of cases were stricture free. Lack of prior RT was the only variable associated with better stricture-free survival after RUER (hazard ratio 6.8, 95% confidence interval 1.10- 42.00, p = 0.037). The study limitations include its retrospective nature and the small number of patients.Conclusions: RUER is a feasible procedure for the management of UESs. Prospective and larger studies are warranted to prove the safety and efficacy of this technique.Patient summary: In this study, we investigate the feasibility of a novel minimally invasive technique for the management of ureteroenteric strictures. We conclude that robotic reimplantation is a feasible and effective procedure. (c) 2021 The Author(s). Published by Elsevier B.V. on behalf of European Association of Urology.
