Introduction: Mortality after radical cystectomy (RC) varies widely in the literature. In cohort studies, mortality rates can vary from as low as 0.5% in large-volume academic centers (2) to as high as 25% in developing countries series. This study aims to perform a systematic review of population-based studies reporting mortality after RC. Methods: A Systematic search was performed in Medline (PubMed®), Embase, and Cochrane for epidemiologic studies reporting mortality after RC. Institutional cohorts and those reporting mortality for specific groups within populations were excluded. Case series and non-epidemiologic series were also excluded. The aim of this review is to evaluate in-hospital mortality (IHM), 30-day mortality (30M), and 90-day mortality (90M). Results: Systematic search resulted in 42 papers comprising 449,661 patients who underwent RC from 1984 to 2017. Mean age was 66.1. Overall IHM, 30M, and 90M were 2.6%, 2.7%, and 4.9%, respectively, with 90M being 2.6 times higher than IHM on average. Lowest IHM was found in Canada and Australia (0.2% and 0.6%, respectively), while the highest IHM was 7.8% (Brazil). Canada and Spain showed the highest 90M (6.5%). 159,584 urinary diversions were analyzed, being mostly ileal conduits (76.8%). Conclusions: The majority of the studies available are from major developed economies with paucity of data in the developing world. 90M after RC tends to be at least twice as high as IHM. The knowledge of such epidemiologic data is vital to guide public policies, such as centralization, in order to reduce mortality.

Aim This review article summarizes the current clinical practice guidelines around disease definitions and risk stratifications, and the treatment of non-muscle-invasive bladder cancer (NMIBC). Recently completed and ongoing clinical trials of novel and investigational therapies in Bacillus Calmette-Guerin (BCG)-naive, BCG-recurrent, and BCG-unresponsive patient populations are also described, e.g., those involving immune checkpoint inhibitors, targeted therapies, other chemotherapy regimens, vaccines, and viral- or bacterial-based treatments. Finally, a brief overview of enhanced cystoscopy and drug delivery systems for the diagnosis and treatment of NMIBC is provided. Background A global shortage of access to BCG is affecting the management of BCG-naive and BCG-recurrent/unresponsive NMIBC; hence, there is an urgent need to assist patients and urologists to enhance the treatment of this disease. Methods Searches of ClinicalTrials.gov, PubMed, and Google Scholar were conducted. Published guidance and conference proceedings from major congresses were reviewed. Conclusion Treatment strategies for NMIBC are generally consistent across guidelines. Several novel therapies have demonstrated promising antitumor activity in clinical trials, including in high-risk or BCG-unresponsive disease. The detection, diagnosis, surveillance, and treatment of NMIBC have also been improved through enhanced disease detection.

Objectives: The aim of this study was to assess the natural history of prostate cancer (PCa) in renal transplant recipients (RTRs) and to clarify the controversy over whether RTRs have a higher risk of PCa and poorer outcomes than non-RTRs, due to factors such as immunosuppression. Patients and Methods: We performed a retrospective multicenter study of RTRs diagnosed with cM0 PCa between 2001 and 2019. Primary outcomes were overall (OS) and cancer-specific survival (CSS). Secondary outcomes included biochemical recurrence and/or progression after active surveillance (AS) and evaluation of variables possibly influencing PCa aggressiveness and outcomes. Management modalities included surgery, radiation, cryotherapy, HIFU, AS, and watchful waiting. Results: We included 166 men from nine institutions. Median age and eGFR at diagnosis were 67 (IQR 60–73) and 45.9 mL/min (IQR 31.5–63.4). ASA score was >2 in 58.4% of cases. Median time from transplant to PCa diagnosis was 117 months (IQR 48–191.5), and median PSA at diagnosis was 6.5 ng/mL (IQR 5.02–10). The biopsy Gleason score was ≥8 in 12.8%; 11.6% and 6.1% patients had suspicion of ≥cT3 > cT2 and cN+ disease. The most frequent management method was radical prostatectomy (65.6%), followed by radiation therapy (16.9%) and AS (10.2%). At a median follow-up of 60.5 months (IQR 31–106) 22.9% of men (n = 38) died, with only n = 4 (2.4%) deaths due to PCa. Local and systemic progression rates were 4.2% and 3.0%. On univariable analysis, no major influence of immunosuppression type was noted, with the exception of a protective effect of antiproliferative agents (HR 0.39, 95% CI 0.16–0.97, p = 0.04) associated with a decreased risk of biochemical recurrence (BCR) or progression after AS. Conclusion: PCa diagnosed in RTRs is mainly of low to intermediate risk and organ-confined at diagnosis, with good cancer control and low PCa death at intermediate follow-up. RTRs have a non-negligible risk of death from causes other than PCa. Aggressive upfront management of the majority of RTRs with PCa may, therefore, be avoided.

Introduction The treatment of choice for high-risk non-muscle invasive bladder cancer (NMIBC) is bacillus Calmette-Guerin (BCG). However, when this fails, the indicated treatment is radical cystectomy. In recent years, trials are being developed with various drugs to avoid this surgery in patients with BCG failure. The aim of this article is to update the treatments under study for bladder preservation in this patient population. Material and Methods Non-systematic review, searching PubMed with the terms "Bladder cancer", "Non-muscle invasive bladder cancer", "NMIBC", "BCG", "BCG-refractory", "Mitomycin C", "MMC", "Hyperthermia", "Electromotive Drug Administration", "EMDA" We used the search engines clinicaltrials.gov and clinicaltrialsregister.eu to find clinical trials. Results The only intravesical drug approved by the Food and Drug Administration (FDA) for carcinoma in situ (CIS) after failure to BCG is valrubicin. Recently, the FDA has approved intravenous pembrolizumab, following the publication of preliminary data from the KEYNOTE-057 study. Atezolizumab has demonstrated similar preliminary efficacy results. Only microwave-induced chemohyperthermia and EMDA-MMC (electromotive drug administration) are recognized as alternatives in European guidelines. Other options under investigation are taxanes and gemcitabine, alone or in combination, recombinant viruses and device-assisted intravesical chemohyperthermia. Conclusions The results of new drugs are promising, with a large number of trials underway. Knowing the mechanisms of resistance to BCG is essential to explore new therapeutic options.

De Novo nephrolithiasis in renal transplant can have severe consequences since renal transplantation involves a single functioning kidney with medical and anatomical specificities (heterotopic transplantation on iliac vessels, immunosuppressive treatments, and comorbidities).To systematically review all available evidence on the prevalence of de novo nephrolithiasis in renal transplant, presentation, and stone characteristics, and to report in a meta-analysis the efficacy of stone treatments (extracorporeal shock wave lithotripsy [ESWL], medical treatment, percutaneous nephrolithotomy [PCNL], open surgery, and ureteroscopy).Medline, Embase, and the Cochrane Library were searched up to November 2021 for all relevant publications reporting the management of de novo nephrolithiasis in renal allografts. The primary outcome was stone-free rate (SFR) at 3 mo. Secondary outcomes included prevalence, stone characteristics (size, density, and composition), symptoms on presentation, need for drainage, complications, and recurrence. Data were narratively synthesized in light of methodological and clinical heterogeneity, and a meta-analysis was performed for SFR. The risk of bias of each included study was assessed.We included 37 retrospective studies with 553 patients and 612 procedures; of the 612 procedures 20 were antegrade ureteroscopy, 154 retrograde ureteroscopy, 118 PCNL, 25 open surgery, 155 ESWL, and 140 surveillance/medical treatment. The prevalence of nephrolithiasis in renal transplant was 1.0%. The mean stone size on diagnosis was 11 mm (2-50). The overall SFR at 3 mo was 82%: 96% with open surgery, 95% with antegrade ureteroscopy, 86% with PCNL, 81% with retrograde ureteroscopy, and 75% with ESWL.De novo nephrolithiasis in renal transplant is an infrequent condition. A high SFR were obtained with an antegrade approach (ureteroscopy, PCNL, and open approach) that should be considered in renal transplant patients owing to the heterotopic position of the renal graft. The choice of technique was correlated with stone size: generally ureteroscopy and ESWL for stones 11-12 mm (mean stone size) versus PCNL and open surgery for 17-25 mm stones.De novo nephrolithiasis in renal transplants is an infrequent situation that can have severe consequences on the function of the renal graft. We evaluated the efficacy of each treatment and noted that antegrade approaches (open surgery, percutaneous nephrolithotomy, and antegrade ureteroscopy) were associated with the highest stone-free rate. As opposed to the management of nephrolithiasis in native kidney, an antegrade approach should be considered more in renal transplant patients.

Context Carcinoma in situ (CIS) of the bladder is defined as a high-grade flat lesion confined to the mucosa. Intravesical treatment with bacillus Calmette–Guerin (BCG) is commonly used to reduce the risk of recurrence and progression; however, CIS of the bladder exhibits a heterogeneous clinical behavior and a significant proportion of patients do not show a primary response. Objective To evaluate the available evidence concerning diagnosis, treatment strategies, follow-up, prognosis, and oncological outcomes in patients with CIS of the bladder. Evidence acquisition A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted using the databases PubMed/MEDLINE and Embase. We included randomized controlled trials, systematic reviews, meta-analyses, and observational studies. Outcomes of interest were: (1) diagnostic strategies, (2) first- and second-line treatments, (3) follow-up strategies, and (4) prognosis and oncological outcomes. Evidence synthesis Overall 62 articles met the inclusion criteria. Most articles concerned retrospective studies and presented mixed data with other non–muscle-invasive bladder cancer categories. The evidence shows that new optical imaging modalities significantly increase the detection rate of CIS. BCG immunotherapy remains the first-line therapy in patients with CIS of the bladder; however, after treatment, adequate follow-up is necessary. Clinicopathological factors remain the main indicators of response to BCG, recurrence, and progression. Conclusions New optical imaging modalities are superior to white light cystoscopy in the detection of CIS of the bladder. There are no robust data that justify consideration of other agents as an alternative to BCG immunotherapy. Despite efforts to identify relevant biomarkers, clinicopathological factors remain the most important prognostic factors. Patient summary New optical techniques have improved the detection of carcinoma in situ (CIS) of the bladder. Bladder preservation using bacillus Calmette-Guerin immunotherapy remains the cornerstone of the treatment of CIS of the bladder.

Objective: Some attempts have previously been made to stratify patients with CIS for the purpose of risk-adapted clinical management and clinical trial design. In particular, two classification systems have been proposed: clinical classification, comprising primary (P-CIS), concomitant (C-CIS), and secondary (S-CIS) disease, and pathological classification, comprising P-CIS, cTa-CIS, and cT1-CIS. The aim of the present study was to assess the impact of both classifications on BCG response, recurrence-free survival (RFS), progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS). Patients and Methods: We performed a retrospective analysis of 386 patients with bladder CIS, with or without associated cTa/cT1 disease, treated with BCG instillations between 2008 and 2015. Patients were stratified according to the two classification systems. Cox multivariate regression models were used to assess the impact of these subtypes on BCG response, RFS, PFS, OS, and CSS. We also performed a cumulative meta-analysis according to PRISMA guidelines. Results: The median follow-up was 70.5 months. According to the clinical classification, 34 (8.8%) patients had P-CIS, 81 (21%) S-CIS, and 271 (70.2%) C-CIS. The pathological classification showed 34 (8.8%) patients to have P-CIS, 190 (49.2%) cTa-CIS, and 162 (42%) cT1-CIS. In the overall cohort, BCG response was reported in 296 (76.7%); 159 (41.2%) had recurrence, 55 (14.2%) had progression, and 67 (17.4%) underwent radical cystectomy. Death from any cause was recorded in 135 (35%) and death from urothelial carcinoma in 38 (9.9%). Cox multivariate regression analysis showed that neither clinical classification nor pathological classification is an independent predictive factor for BCG response, RFS, PFS, OS, or CSS after adjusting for confounders. In the pooled meta-analysis, two studies and the present series were included for evidence synthesis, recruiting a total of 941 patients. We found no statistically significant difference across the groups for both classifications with respect to BCG response, RFS, PFS, and CSS. Conclusions: Currently, the supporting evidence for an impact of clinical classification and pathological classification on oncological outcomes of CIS of the bladder is insufficient to justify their use to guide clinical management or follow-up.

Item does not contain fulltext INTRODUCTION: We aimed to compare the outcomes of open vs robotic partial nephrectomy (PN), focusing on predictors of Trifecta failure in patients with highly complex renal masses. PATIENTS AND METHODS: We queried the prospectively collected database from the SIB International Consortium, including 507 consecutive patients with cT1-2N0M0 renal masses treated at 16 high-volume referral centres, to select those with highly complex (PADUA score ≥10) tumors undergoing PN. RT was classified as enucleation, enucleoresection or resection according to the SIB score. Trifecta was defined as achievement of negative surgical margins, no acute kidney injury and no Clavien-Dindo grade ≥2 postoperative surgical complications. Multivariable logistic regression analysis was used to assess independent predictors of Trifecta failure. RESULTS: 113 patients were included. Patients undergoing open PN (n = 47, 41.6%) and robotic PN (n = 66, 58.4%) were comparable in baseline characteristics. RT was classified as enucleation, enucleoresection and resection in 46.9%, 34.0% and 19.1% of open PN, and in 50.0%, 40.9% and 9.1% of robotic PN (p = 0.28). Trifecta was achieved in significantly more patients after robotic PN (69.7% vs. 42.6%, p = 0.004). On multivariable analysis, surgical approach (open vs robotic, OR: 2.62; 95%CI: 1.11-6.15, p = 0.027) and tumor complexity (OR for each additional unit of the PADUA score: 2.27; 95%CI: 1.27-4.06, p = 0.006) were significant predictors of Trifecta failure, while RT was not. The study is limited by lack of randomization; as such, selection bias and confounding cannot be entirely ruled out. CONCLUSIONS: Tumor complexity and surgical approach were independent predictors of Trifecta failure after PN for highly complex renal masses.

Background: To explore predictors of positive surgical margins (PSM) after robotic partial nephrectomy (PN) in a large multicenter international observational project, harnessing the Surface-Intermediate-Base (SIB) margin score to report the resection technique after PN in a standardized way. Methods: Data from consecutive patients with cT1-2N0M0 renal masses treated with PN from September 2014 to March 2015 at 16 tertiary referral centers and included in the SIB margin score International Consortium were prospectively collected. For the present study, only patients treated with robotic PN were included. Uni- and multivariable analysis were fitted to explore clinical and surgical predictors of PSMs after PN. Results: Overall, 289 patients were enrolled. Median (IQR) preoperative tumor size was 3.0 (2.3–4.2) cm and median (IQR) PADUA score was 8 (7–9). SIB scores of 0–2 (enucleation), 3–4 (enucleoresection) and 5 (resection) were reported in 53.3%, 27.3% and 19.4% of cases, respectively. A PSM was recorded in 18 (6.2%) patients. PSM rate was 4.5%, 11.4% and 3.6% in case of enucleation, enucleoresection and resection, respectively. Patients with PSMs had tumors with a higher rate of contact with the urinary collecting system (55.6% vs. 27.3%; p < 0.001) and a longer median warm ischemia time (22 vs. 16 min; p = 0.02) compared with patients with negative surgical margins, while no differences emerged between the two groups in terms of other tumor features (i.e., pathological diameter, PADUA score). In multivariable analysis, only enucleoresection (SIB score 3–4) versus enucleation (SIB score 0–2) was found to be an independent predictor of PSM at final pathology (HR: 2.68; 95% CI: 1.25–7.63; p = 0.04), while resection (SIB score 5) was not. Conclusions: In our experience, enucleoresection led to a higher risk of PSMs as compared to enucleation. Further studies are needed to assess the differential impacts of resection technique and surgeon’s experience on margin status after robotic PN.

TPS583 Background: Treatment options are limited for pts with NMIBC and MIBC who experience disease recurrence or who are ineligible for or refuse standard of care. Erda, an oral selective pan-FGFR tyrosine kinase inhibitor, is approved in adults with locally advanced or metastatic urothelial cancer with select FGFR3/2 alterations ( alt) who have progressed during or after ≥1 line of platinum-containing chemotherapy. FGFRalt are among the most common oncogenic drivers detected in NMIBC and MIBC, and are more prevalent in NMIBC. TAR-210 is an intravesical drug delivery system designed to provide local, continuous release of erda within the bladder, thus limiting systemic toxicity. This study evaluates the safety, pharmacokinetics (PK), and efficacy of TAR-210 in pts with NMIBC or MIBC with select FGFRalt. Methods: Open-label, multicenter phase 1 study of TAR-210 in pts with recurrent NMIBC or MIBC (NCT05316155). Eligible pts are aged ≥18 yrs with adequate organ function and tumors with select FGFRalt. A flexible molecular eligibility strategy is used to allow for local or central fresh/archival tissue-based FGFR testing by next-generation sequencing (NGS) or PCR, or urine cell-free DNA NGS testing. Four cohorts will be enrolled: pts with recurrent, bacillus Calmette-Guerin (BCG)-experienced papillary-only high-risk (HR) NMIBC (high-grade Ta/T1) refusing or ineligible for radical cystectomy (RC) (Cohort 1) or scheduled for RC (Cohort 2); pts with recurrent, intermediate-risk NMIBC (Ta/T1) with a history of low-grade disease (Cohort 3); pts with cT2-T3a MIBC scheduled for RC refusing or ineligible for neoadjuvant cisplatin (Cohort 4). Pts in Cohorts 1 and 2 will have TURBT with resection of all visible disease prior to dosing, whereas pts in Cohort 3 must have visible disease prior to dosing. The primary end point is safety (adverse events, including dose-limiting toxicity). Secondary end points include PK, recurrence-free survival (Cohorts 1 and 2), complete response (CR) rate and duration of CR (Cohort 3), and pathologic CR rate, pT0 rate, and rate of downstaging to

The best predictors of response to intravesical immunotherapy are tumor grade and stage, tumor recurrence pattern, nomograms, panels of urinary cytokines, and fluorescent in situ hybridization patterns of urine cytology examinations. Future investigations on predictors of Bacillus Calmette-Guerin efficacy are needed to better select those patients who will really benefit from a conservative treatment. Hardly any of the proposed nomograms were designed to precisely predict the outcome of Bacillus Calmette-Guerin immunotherapy. A new nomogram for NMIBC recurrence and progression based on all non-muscle-invasive bladder cancer subgroups would include factors already proven in cancer prognosis and prediction.

Resumen Introduccion y objetivos Existen varios estudios con el objetivo de validar las tablas del Club Urologico Espanol de Tratamiento Oncologico (CUETO). Sin embargo, ninguno de estos estudios se ha centrado en el cancer de vejiga de alto y muy alto riesgo. El objetivo del presente estudio fue validar externamente el modelo CUETO para predecir la recidiva y la progresion de la enfermedad en el grupo de tumores T1G3 tratados con bacilo Calmette-Guerin (BCG). Pacientes o materiales y metodos Se analizaron los datos de 414 pacientes con cancer de vejiga T1G3 primario. Para evaluar la discriminacion del modelo se usaron modelos de riesgos proporcionales de Cox y se calcularon los indices de concordancia. Resultados La mediana de seguimiento fue de 68 meses. Se observo recidiva en 212 (51,2%) y 64 pacientes (15,5%) experimentaron mas de un episodio de recurrencia durante el periodo de seguimiento. La progresion del cancer se observo en 106 pacientes (25,6%), 115 pacientes (27,8%) fueron tratados con cistectomia radical, y hubo 64 (15,5%) muertes por tumor. Para la probabilidad de recidiva y progresion, el indice de concordancia de los modelos CUETO fue de 0,633 y 0,697, respectivamente. Las tablas de CUETO subestimaron significativamente el riesgo de recidiva y marginalmente el riesgo de progresion en el primer ano de observacion. Durante los 5 anos de observacion, la tendencia de la recidiva fue mucho menos clara. Por el contrario, hubo una ligera sobreestimacion en el riesgo de progresion. El estudio esta limitado por su naturaleza retrospectiva. Conclusiones Se demostro que las tablas de riesgo del grupo CUETO logran una discriminacion correcta, tanto para la recidiva de la enfermedad como para la progresion, en pacientes con T1G3 tratados con BCG. El modelo de puntuacion (CUETO) subestima el riesgo de recidiva del tumor, pero acierta al predecir el riesgo de progresion.

OBJECTIVE To assess whether bacillus Calmette-Guerin (BCG) responsiveness after initiation of an adequate BCG treatment (at least five of six instillations of induction and at least two of three instillations of maintenance) impacts oncological outcomes in patients with carcinoma in situ (CIS) of the bladder treated with BCG immunotherapy. PATIENTS AND METHODS Data were available for 193 patients with bladder CIS with or without associated cTa/cT1 disease who received an adequate BCG treatment between 2008 and 2015. Bladder biopsies were taken at 6 months and patients were then stratified as either BCG responsive (negative biopsies) or BCG unresponsive (positive biopsies). Inverse probability weighting (IPW)-adjusted Kaplan-Meier and IPW-adjusted Cox regression were performed to compare progression-free survival (PFS), radical cystectomy-free survival (RCFS), overall survival OS, and cancer-specific survival (CSS) in the two groups. RESULTS AND LIMITATIONS Comparing the BCG-responsive and BCG-unresponsive groups, IPW-adjusted Kaplan-Meier analysis revealed, respectively, a median (interquartile range) of PFS of 9 (5-15) vs 48.5 (28-77) months (P = 0.001), a RCFS of 11 (9-15) vs 49 (24-76) months (P

Background: Kidney transplantation (KT) is the best renal replacement treatment. The rewarming time is associated with ischemia/reperfusion damage. In both the open (open KT [OKT]) and the robotic (robotic-assisted KT [RAKT]) approaches, ice slush is used to maintain graft temperature (T degrees) below 20 degrees C. This may result in nonhomogeneous graft T degrees maintenance and, particularly during RAKT where the graft is completely inside the abdominal cavity, rises concerns regarding systemic hypothermia. Objective: To design a cold ischemia device (CID) to maintain a constant and homogeneous low graft T degrees during surgery. Design, setting, and participants: In IDEAL phase 0, a CID was developed and tested to determine its cooling effect on the kidney inside a closed system at 37.5 degrees C, by comparing it with kidney alone versus a gauze-jacket filled with ice slush. The CID was evaluated in pigs undergoing OKT and RAKT, assessing feasibility and adverse reactions. In IDEAL phase 1, the CID was tested in human OKT and RAKT. Surgical procedure: OKT and RAKT. Measurements: In all phases, T degrees was evaluated at scheduled time points. Results and limitations: In the preliminary tests of IDEAL phase 0, the CID was able to maintain a low graft T degrees and superiority to other groups (p = 0.002). In the in vivo animal model, the CID maintained a low and constant graft T degrees in OKT (n = 3) and RAKT (n = 3), with a mean T degrees at 50 min of 10.8 degrees C and 14.9 degrees C, respectively. IDEAL phase 1 demonstrated feasibility of both approaches (OKT, n = 2 and RAKT, n = 3) using the CID, and graft T degrees never exceeded 20 degrees C (mean T degrees: OKT 15.7 degrees C vs RAKT 18.3 degrees C). No complications were recorded. The main limitation consists in the low number of participants. Conclusions: The CID assured a constant low graft T degrees during rewarming time, in both OKT and RAKT. Patient summary: A cold ischemia device (CID) is the first step toward a feasible, safe, and reproducible method to maintain a low graft temperature during surgery. The employment of a CID may optimize the functional outcomes. (c) 2021 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Urinary diversion (UD) is a technically demanding surgery even after decades of its implementation. Although multiple UD techniques have been described, ileal conduit remains the most frequent, probably due to its easy and quick construction. The individual selection of UD should be based on the balance between the oncological control and quality of life, taking into account the technical feasibility, health status performance, and life expectancy. In this chapter, we describe step by step the specific technical aspects for incontinent urinary diversions construction with special emphasis on the ileal conduit. Despite the surgical experience accumulated in specialized centers, the ileal conduit is associated with significant morbidity, the incidence of complications for ileal is about 66%, and there have been classified in early ( 90 days), which, they will be discussed in this chapter. For these reasons, current efforts are focused on the implementation of the enhanced recovery after surgery protocol, which has shown to be useful in the postoperative recovery of the patients. In this chapter, we cover the indications, surgical aspects, complications, and follow-up of patients undergoing incontinent UD.

Purpose: To describe the technique as well as the oncological and functional outcomes of partial salvage prostatic cryoablation (SCAP) in the treatment of local recurrent prostate cancer after primary radiotherapy. Materials and methods: The indications for partial SCAP were: PSA10 years and PSA doubling time >12 months. Cryoablation was performed with the Precise© device (Galil MedicalⓇ, Arden Hills, Minnesota, USA). Results: Fourteen patients underwent partial SCAP from 09/2010 to 09/2018. Primary treatment consisted of: 29% brachytherapy and 71% EBRT with concomitant androgen deprivation therapy (ADT) in 50%. Median time to recurrence was 8.5 years [3.2–19.3]. At the time of cryotherapy, median age was 72 years [58–84], Charlson was 3 [1–6] and serum PSA was 4.2 [2.2–9.0]. Mean procedure time was 90 min [60–120]. Median hospital stay and catheter duration were respectively 2 days [2–6] and 8 days [3–14]. Median biochemical disease-free survival was 4.4 years and 71% of the patients were free of third-line treatment at the time of evaluation. No patient developed metastasis, and all were alive at the time of the last evaluation. De novo urinary incontinence was reported in one patient and de novo erectile dysfunction in one patient. Conclusions: Partial SCAP was an alternative to salvage prostatectomy and whole gland ablation for highly selected patients with locally recurrent PCa after radiotherapy. It significantly avoided or at least delayed the need for ADT.

Background To evaluate demographic, clinical and pathological characteristics of small renal masses (SRM) (≤ 4 cm) in a Latin-American population provided by LARCG (Latin-American Renal Cancer Group) and analyze predictors of survival, recurrence and metastasis. Methods A multi-institutional retrospective cohort study of 1523 patients submitted to surgical treatment for non-metastatic SRM from 1979 to 2016. Comparisons between radical (RN) or partial nephrectomy (PN) and young or elderly patients were performed. Kaplan-Meier curves and log-rank tests estimated 10-year overall survival. Predictors of local recurrence or metastasis were analyzed by a multivariable logistic regression model. Results PN and RN were performed in 897 (66%) and 461 (34%) patients. A proportional increase of PN cases from 48.5% (1979–2009) to 75% (after 2009) was evidenced. Stratifying by age, elderly patients (≥ 65 years) had better 10-year OS rates when submitted to PN (83.5%), than RN (54.5%), p = 0.044. This disparity was not evidenced in younger patients. On multivariable model, bilaterality, extracapsular extension and ASA (American Society of Anesthesiologists) classification ≥3 were predictors of local recurrence. We did not identify significant predictors for distant metastasis in our series. Conclusions PN is performed in Latin-America in a similar proportion to developed areas and it has been increasing in the last years. Even in elderly individuals, if good functional status, sufficiently fit to surgery, and favorable tumor characteristics, they should be encouraged to perform PN. Intending to an earlier diagnosis of recurrence or distant metastasis, SRM cases with unfavorable characteristics should have a more rigorous follow-up routine.

Purpose of review The standard diagnosis of carcinoma in situ (CIS) of the bladder, based on white light cystoscopy and urine cytology, is limited because CIS can vary from normal-appearing mucosa to a lesion indistinguishable from an inflammatory process. Intravesical instillation of Bacillus Calmette-Guerin (BCG) remains first-line therapy; however, a significant proportion of cases persist or recur after BCG treatment. This review summarizes recent improvements in the detection and treatment of CIS. Recent findings The new optical technologies improve CIS detection, with a potential positive impact on oncological outcomes. The usefulness of MRI-photodynamic diagnosis fusion transurethral resection in CIS detection is unclear and further studies are needed. BCG instillation remains the first-line therapy in CIS patients and seems to improve recurrence and progression rates, especially with the use of maintenance. Intravesical device-assisted therapies could be effective in both BCG-naive and BCG-unresponsive CIS patients, but further studies are ongoing to clarify their clinical benefit. A phase II clinical trial with pembrolizumab has shown the potential effectiveness of immune checkpoint inhibitors in BCG-unresponsive CIS patients and further trials are ongoing. Summary New optical techniques increase the CIS detection rate. BCG instillation remains the first-line treatment. Immune checkpoint inhibitors could be a future alternative in BCG-naive and BCG-unresponsive CIS patients.

Background: A non-negligible proportion of individuals diagnosed with cT1 renal cell carcinoma (RCC) are upstaged to pT3a at final pathology. Few data on oncological outcomes for these patients are available to determine whether partial nephrectomy (PN) might jeopardise cancer control. Objective: To assess, within an international multi-institutional collaboration, whether PN might undermine cancer control relative to radical nephrectomy (RN) in RCC patients with unexpected pT3a disease. Design, setting, and participants: International multi-institutional collaboration including patients with cT1abN0M0-pT3a RCC. Intervention: PN or RN. Outcome measurements and statistical analysis: We used Kaplan-Meier analyses, before and after propensity-score matching, to evaluate differences in metastatic progression (MP) and cancer-specific mortality (CSM) rates during follow-up. Univariable and multivariable Cox regression analyses were used to assess predictors of MP and CSM. Results and limitations: Overall, 309 patients with cT1abN0M0 RCC (cT1aN0M0, n = 107, 34.6%; cT1bN0M0, n = 202, 65.4%) had pT3a disease according to final pathology. Patients were treated with either PN (n = 71, 23%) or RN (n = 238, 77%). MP at 1, 2, and 5 yr was detected in 9.1%, 13.3%, and 24.1% of patients, respectively. CSM was 3.5%, 10.7%, and 18.4% at 1, 2, and 5 yr, respectively. After matching, no difference in terms of MP or CSM was observed between the PN and RN cohorts (both p>0.3). On multivariable analysis, type of surgery (PN vs RN) was not an independent predictor of either MP (p = 0.3) or CSM (p = 0.4). Limitations include the retrospective design. Conclusions: In patients with unexpected pT3a RCC at final pathology, PN does not appear to jeopardise cancer control with regard to MP and CSM. Patient summary: Cancer control is similar between patients treated with removal of the entire kidney and those with only partial removal, even if the final histology examination demonstrates a tumour that is unexpectedly not confined within the kidney. Partial nephrectomy does not undermine cancer control when unexpected pT3a renal cancer is identified at final pathology.

Context The European Association of Urology (EAU) panel on renal transplantation (RT) has released an updated version of the RT guidelines. Objective To present the 2018 EAU guidelines on RT. Evidence acquisition A broad and comprehensive scoping exercise was performed, encompassing all areas of RT guidelines published between January 1, 2007, and May 31, 2016. Databases covered by the search included Medline, Embase, and the Cochrane Libraries. Previous guidelines were updated, and levels of evidence and grades of recommendation were assigned. Evidence synthesis It is strongly recommended to offer pure or hand-assisted laparoscopic/retroperitoneoscopic surgery as the preferential technique for living donor nephrectomy. Decisions on the acceptance of a donor organ should not be based on histological findings alone since this might lead to an unnecessarily high rate of discarded grafts. For ureterovesical anastomosis, a Lich-Gregoir-like extravesical technique protected by a ureteral stent is the preferred technique for minimisation of urinary tract complications. It is also strongly recommended to perform initial rejection prophylaxis with a combination therapy comprising a calcineurin inhibitor (preferably tacrolimus), mycophenolate, steroids, and an induction agent (either basiliximab or anti-thymocyte globulin). The long version of the guidelines is available at the EAU website ( http://uroweb.org/guidelines ). Conclusions These abridged EAU guidelines present updated information on the clinical and surgical management of RT for incorporation into clinical practice. Patient summary The European Association of Urology has released the renal transplantation guidelines. The implementation of minimally invasive surgery for organ retrieval and the latest evidence on transplant surgery as well as on immunosuppressive regimens are key factors for minimisation of rejection and achievement of long-term graft survival.

Background: Ureteroarterial fistula (UAF) represents an uncommon complication after urological surgery; however, this is a well-documented condition in patients with predisposing risk factors. The aim of the present study is to report and analyze the endovascular management of a series of patients with UAF, treated in authors’ hospital, and to report and analyze the same data concerning patients retrieved from a systematic literature review. Methods: Authors conducted a retrospective analysis of prospectively collected data and a systematic literature review. The research was carried out through PubMed database searching the following keywords: “uretero arterial fistula” and “uretero iliac fistula.” It includes only articles reporting the endovascular management. Results: Forty-six articles were included in the present study for a total of 94 patients. Risk factors were as follows: chronic indwelling ureteral stents, pelvic surgery, radiotherapy, iliac artery pseudo-aneurysm, and chemotherapy. All patients had gross hematuria at presentation. Stent graft placement was performed in 89 patients, embolization in 5 patients, and iliac internal artery embolization combined with stent graft placement was performed in 24 patients. Four postprocedural complications were observed (4.2%). During a median follow-up of 8 months, 10 complications related to UAF were observed (10.6%): rebleeding (7 cases) and stent thrombosis (3 cases). Two patients died for causes related to UAF (2.1%): rebleeding (1) and retroperitoneal abscess (1). Conclusion: Based on the present data, endovascular treatment is feasible and safe with low postprocedural complications and mortality rate. Considering the increase in surgery and radiotherapy performed, UAF should be always debated in patients with massive hematuria.

Objectives: To assess whether the use of endoscopic exploration (EE) as a routine diagnostic tool in patients with clinical suspicion of upper tract urothelial carcinoma (UTUC) following radical cystectomy (RC) significantly impacts management decision-making and to describe the oncological outcomes of patients with UTUC after RC. Materials and methods: We performed a retrospective review of medical records of patients with suspicion of UTUC after RC between 2000 and 2019. Patient demographics, clinicopathological features, treatments, and outcomes were analyzed. Results: We identified 60 patients with suspicion of UTUC. After diagnostic work-up, 16 were submitted to radical nephroureterectomy (RNU) and 44 underwent diagnostic EE. After EE, a further 18/44 (40.9%) were submitted to RNU, while no evidence of tumor was found in 12 (27.3%) and the remaining 12 (27.3%) underwent endoscopic treatment (ET). Thus, in 24/44 (54.5%) patients the primary treatment strategy, i.e., RNU, was altered. Twenty-nine (85.3%) of the 34 patients who underwent RNU had high-grade tumors and 16 (47%) had the muscle-invasive disease. In the ET group, 6 (50%) had high-grade tumors and 10 (83.4%) had tumors less than 2 cm. The 5-year estimated recurrence-free survival and cancer-specific survival were, respectively, 58.4% and 45.6% in the RNU group and 25% and 80.8% in the ET group. Conclusion: EE significantly impacts clinical decision-making in patients with suspicion of UTUC after RC, resulting in a change in treatment strategy in approximately half of the patients. UTUC following RC has a poor prognosis and although RNU is the gold standard, ET could be considered in a selected group of patients. (C) 2021 Elsevier Inc. All rights reserved.

Purpose The aim of this study was to analyse the influence of age on the treatment outcome and toxicity in patients with T1HG non-muscle invasive bladder cancers treated with BCG immunotherapy. Methods Data from 637 patients with primary T1HG bladder cancer who were treated between 1986 and 2016 in two academic centres were retrospectively reviewed. Median follow-up was 57 months. Patients were divided into two groups: younger (< 70 years old) and older (>= 70 years old). Additional analyses in subgroups of older (> 75 and > 80) patients were performed. Log-rank test, Cox regression analysis, and propensity score matching were performed to compare the groups. Results There were 389 patients below and 248 patients above or equal 70 years old. Recurrence-free, progression-free, and cancer-specific survival rates did not differ significantly between younger and older patients. Recurrence-free survival for younger and older patients were 55.4% vs 52.9%, progression-free survival 75.9% vs 76.6%, and cancer-specific survival were 87.5% vs 89.9% (all p > 0.05). Differences in the oldest subgroups also did not reach statistical significance. In both regression analysis and propensity score matching, no statistically significant associations of age with any of analysed end-points were found. Finally, there were no statistically significant differences between younger and older group in terms of moderate and severe complications occurrence (47.6% vs. 44.5%; p > 0.05) Conclusions It was shown that increasing age was not associated with BCG immunotherapy oncological outcomes, or with BCG toxicity in T1HG non-muscle invasive bladder cancer.

Purpose: The impact of resection technique on partial nephrectomy outcomes is controversial. The aim of this study was to evaluate the pattern of resection techniques during partial nephrectomy and the impact on perioperative outcomes, acute kidney injury, positive surgical margins and the achievement of the Trifecta (negative surgical margins, no perioperative Clavien-Dindo grade 2 or greater surgical complications and no postoperative acute kidney injury). Materials and Methods: We prospectively collected data on consecutive patients with cT1-2N0M0 renal masses treated with partial nephrectomy at a total of 16 referral centers from September 2014 to March 2015. After partial nephrectomy the resection technique was classified by the surgeon as enucleation, enucleoresection or resection according to the SIB (Surface-Intermediate-Base) margin scores 0 to 2, 3 or 4 and 5, respectively. Multivariable logistic regression analysis was done to evaluate the potential impact of the resection technique on postoperative surgical complications, positive surgical margins, acute kidney injury and Trifecta achievement. Results: Overall 507 patients were included in analysis. The resection technique was classified as enucleation in 266 patients (52%), enucleoresection in 150 (30%) and resection in 91 (18%). The resection technique (enucleoresection vs enucleation and resection) was the only significant predictor of positive surgical margins. Tumor complexity, surgical approach (open and laparoscopic vs robotic) and resection technique (enucleoresection vs enucleation) were significant predictors of Clavien-Dindo grade 2 or greater surgical complications. The surgical approach (open and laparoscopic vs robotic), the resection technique (enucleoresection vs enucleation) and warm ischemia time were significantly associated with postoperative acute kidney injury and Trifecta achievement. Conclusions: Resection techniques significantly impact surgical complications, early functional outcomes and positive surgical margins after partial nephrectomy of localized renal masses.

OBJECTIVE To analyze the outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) in octogenarian patients. METHODS The RESURGE (REnal SUrgery in the Eldely) multi-institutional database was queried to identify patients >= 80 years old who had undergone a PN or RN for a renal tumor. Multivariable binary logistic regression estimated the association between type of surgery and occurrence of complications. Multivariable Cox regression model assessed the association between type of surgery and All-Causes Mortality. RESULTS The study analyzed 585 patients (median age 83 years, IQR 81-84), 364 of whom (62.2%) underwent RN and 221 (37.8%) PN. Patients undergoing RN were older (P = .0084), had larger tumor size (P < .0001) and higher clinical stage (P < .001). At multivariable analysis for complications, the only significant difference was found for lower risk of major postoperative complications for laparoscopic RN compared to open RN (OR: 0.42; P = .04). The rate of significant (>25%) decrease of eGFR in PN and RN was 18% versus 59% at 1 month, and 23% versus 65% at 6 months (P < .0001). After a median follow-up time of 39 months, 161 patients (31%) died, of whom 105 (20%) due to renal cancer. CONCLUSION In this patient population both RN and PN carry a non-negligible risk of complications. When surgical removal is indicated, PN should be preferred, whenever technically feasible, as it can offer better preservation of renal function, without increasing the risk of complications. Moreover, a minimally invasive approach should be pursued, as it can translate into lower surgical morbidity. (C) 2019 Elsevier Inc.

Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy. A prospective pilot study was made at Fundacio Puigvert (Barcelona), evaluating functional and surgical outcomes. In this series, we considered the functional results, surgical outcomes and complications rates. Seventeen patients successfully underwent RAKT, in particular surgical console time was 181 min (150–200) with vascular suture time 42 min (32–48), and estimated blood loss

Background Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. Methods The records of 413 patients collected by the International Renal Cell Carcinoma–Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan–Meier estimate and Cox regression analyses investigated the impact of TC on CSS in addition to established clinicopathological predictors. Results VTT was solid in 225 patients and friable in 188 patients. Median CSS was 50 months in solid and 45 months in friable VTT. TC showed no significant association with metastatic spread, pT stage, perinephric fat invasion, and higher Fuhrman grade. Survival analysis and Cox regression rejected TC as prognostic marker for CSS. Conclusions In the largest cohort published so far, TC seems not to be independently associated with survival in RCC patients and should therefore not be included in risk stratification models. J.

To describe the perioperative and oncology outcomes in a series of laparoscopic or robotic partial nephrectomies (PN) for renal tumors treated in diverse institutions of Hispanic America from the beginning of their minimally invasive (MI) PN experience through December 2014. Seventeen institutions participated in the CAU generated a MI PN database. We estimated proportions, medians, 95 % confidence intervals, Kaplan-Meier curves, multivariate logistic and Cox regression analyses. Clavien-Dindo classification was used. We evaluated 1501 laparoscopic (98 %) or robotic (2 %) PNs. Median age: 58 years. Median surgical time, warm ischemia and intraoperative bleeding were 150, 20 min and 200 cc. 81 % of the lesions were malignant, with clear cell histology being 65 % of the total. Median maximum tumor diameter is 2.7 cm, positive margin is 8.2 %, and median hospitalization is 3 days. One or more postoperative complication was recorded in 19.8 % of the patients: Clavien 1: 5.6 %; Clavien 2: 8.4 %; Clavien 3A: 1.5 %; Clavien 3B: 3.2 %; Clavien 4A: 1 %; Clavien 4B: 0.1 %; Clavien 5: 0 %. Bleeding was the main cause of a reoperation (5.5 %), conversion to radical nephrectomy (3 %) or open partial nephrectomy (6 %). Transfusion rate is 10 %. In multivariate analysis, RENAL nephrometry score was the only variable associated with complications (OR 1.1; 95 % CI 1.02-1.2; p = 0.02). Nineteen patients presented disease progression or died of disease in a median follow-up of 1.37 years. The 5-year progression or kidney cancer mortality-free rate was 94 % (95 % CI 90, 97). Positive margins (HR 4.98; 95 % CI 1.3-19; p = 0.02) and females (HR 5.6; 95 % CI 1.7-19; p = 0.005) were associated with disease progression or kidney cancer mortality after adjusting for maximum tumor diameter. Laparoscopic PN in these centers of Hispanic America seem to have acceptable perioperative complications and short-term oncologic outcomes.

Introduction and objectives: Various studies tried to validate Club Urologico Espanol de Tratamiento Oncologico (CUETO) tables, yet, none of this papers focused on the high and very high risk bladder cancers. The aim of the study was to externally validate the CUETO model for predicting disease recurrence and progression in group of T1G3 tumors treated with BCG immunotherapy. Patients or materials and methods: Data from 414 patients with primary T1G3 bladder cancer were analysed. To evaluate the model discrimination, Cox proportional hazard regression models were created and concordance indexes were calculated. Results: The median follow-up was 68 months. The recurrence was observed in 212 (51.2%) and 64 patients (15.5%) experienced the recurrence more than once during the study follow-up. Progression of the cancer was observed in 106 patients (25.6%). Radical cystectomy was performed in 115 patients (27.8%) and there were 64 (15.5%) cancer specific deaths. For recurrence and progression probability, the concordance index of the CUETO models was 0.633 and 0.697 respectively. CUETO tables underestimated significantly the risk of recurrence and marginally the risk of progression in the first year of observation. For 5 years of observation, the trend for the recurrence was much less clear. On the contrary, there was slight overestimation in the risk of progression. The study is limited by retrospective nature. Conclusions: It was shown that the CUETO risk tables exhibit a fair discrimination for both disease recurrence and progression in T1G3 patients treated with BCG. CUETO scoring model underestimates the risk of tumor recurrence, but predicts well risk of progression. (C) 2019 AEU. Published by Elsevier Espana, S.L.U. All rights reserved.

Introduction and objectives: The aim of this study was to analyse prognostic impact of tumour histological grade on survival differences between primary G2 and G3 WHO1973 stage T1 tumours which were graded as HG according to WHO2004 grading system. Materials and methods: Data from 481 patients with primary T1HG bladder cancer who were treated between 1986 and 2016 in 2 university centres were retrospectively reviewed. Log-rank test and Cox regression analysis was performed to compare the groups. Results: 95 (19,8%) tumours were classified as G2 and 386 (80,2%) were G3. Median follow-up was 68 months. The recurrence was observed in 228 (47,5%), and progression in 109 patients (22,7%). Radical cystectomy was performed in 114 pts (23,7%) and there were 64 (13,3%) cancer specific deaths. Recurrence-free rates at 5-years follow-up for G2, G3 and all patients were 68,7%, 51,2% and 56,3% and progression-free rates were 89,3%, 73,2% and 78,1% respectively. For total observation period patients with G3 tumours presented also worse recurrence-free, and progression-free survival levels than patients with G2 tumours. In multivariate analysis, after adjustment for clinical features, the risk of recurrence and progression for G3 tumours was 1,65 and 2,42 fold higher than for G2 tumours. Conclusions: It was shown that G3 T1 tumours are characterized by worse recurrence free and progression free survivals when compared to G2 cancers. (C) 2019 AEU. Published by Elsevier Espana, S.L.U.
