  • Recent evidence for anatomic endoscopic enucleation of the prostate (AEEP)
           in patients with benign prostatic obstruction on antiplatelet or
           anticoagulant therapy
    • Abstract: Introduction Due to demographic changes in today's society, the number of patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) is increasing. Similarly, the proportion of patients with cardiovascular risk factors undergoing antiplatelet (AP) or anticoagulation (AC) therapy is growing as well. Methods This review discusses the current literature on various techniques used for anatomic endoscopic enucleation of the prostate (AEEP) in patients on AC/AP therapy. Results The large number of energy sources used for AEEP makes it difficult to compare them. Overall, fewer bleeding-associated complications arise in patients under AP compared to AC or bridging therapy with low molecular weight heparin. However, perioperatively both AP and AC therapy lead to a higher risk of bleeding complications compared to patients not taking anticoagulants. Conclusions The literature shows that AEEP is possible and efficacious in patients under AC/AP therapy, with only slight differences compared to patients not taking AC/AP drugs, on a short and long-term basis. Nevertheless, the sparse data, the retrospective nature of many studies and the inclusion of prostate sizes between 50 and 110 ml only, make it difficult to come to strong conclusions.

  • Association of patients’ sex with treatment outcomes after intravesical
           bacillus Calmette–Guérin immunotherapy for T1G3/HG bladder cancer
    • Abstract: Purpose To investigate the association of patients’ sex with recurrence and disease progression in patients treated with intravesical bacillus Calmette–Guérin (BCG) for T1G3/HG urinary bladder cancer (UBC). Materials and methods We analyzed the data of 2635 patients treated with adjuvant intravesical BCG for T1 UBC between 1984 and 2019. We accounted for missing data using multiple imputations and adjusted for covariate imbalance between males and females using inverse probability weighting (IPW). Crude and IPW-adjusted Cox regression analyses were used to estimate the hazard ratios (HR) with their 95% confidence intervals (CI) for the association of patients’ sex with HG-recurrence and disease progression. Results A total of 2170 (82%) males and 465 (18%) females were available for analysis. Overall, 1090 (50%) males and 244 (52%) females experienced recurrence, and 391 (18%) males and 104 (22%) females experienced disease progression. On IPW-adjusted Cox regression analyses, female sex was associated with disease progression (HR 1.25, 95%CI 1.01–1.56, p = 0.04) but not with recurrence (HR 1.06, 95%CI 0.92–1.22, p = 0.41). A total of 1056 patients were treated with adequate BCG. In these patients, on IPW-adjusted Cox regression analyses, patients’ sex was not associated with recurrence (HR 0.99, 95%CI 0.80–1.24, p = 0.96), HG-recurrence (HR 1.00, 95%CI 0.78–1.29, p = 0.99) or disease progression (HR 1.12, 95%CI 0.78–1.60, p = 0.55). Conclusion Our analysis generates the hypothesis of a differential response to BCG between males and females if not adequately treated. Further studies should focus on sex-based differences in innate and adaptive immune system and their association with BCG response.

  • Testicular ultrasound underestimates the size of small testicular masses:
           a radiologic–pathologic correlation study
    • Abstract: Purpose Increasing use and resolution of testicular ultrasound imaging has resulted in a greater diagnosis of non-palpable small testicular masses and subsequent over-treatment with orchiectomy. Our aim was to determine the diagnostic accuracy of testicular ultrasound to accurately determine the pathologic size of small testicular masses (SMTMs) and to evaluate the association of various measurements with benign pathology. Methods Retrospectively, an institutional testicular cancer database was reviewed to evaluate the patients who underwent an orchiectomy for a testicular mass seen on ultrasound from 2003 to 2017. Three-dimensional measurements were compared from the ultrasound and pathology specimens, including other measures such as tumor volume and percentage of testicular volume. Finally, the predictive accuracy of maximum diameter and tumor volume to predict benign pathology was evaluated using receiver-operating curve analysis. Results We identified 208 patients and showed that ultrasound significantly underestimated sub-centimeter testicular masses (mean difference 0.56 cm, 95%CI 0.89–0.14, p = 0.004) and testicular masses between 1 and < 2 cm (mean difference 0.50 cm, 95%CI 0.97–0.15, p = 0.009). Tumor volume measured on ultrasound was consistently similar to pathologic tumor volume across all sizes and was significantly correlated (Spearman’s Rho = 0.81). Mass volume had a greater predictive accuracy for benign pathology than maximum diameter using a 1 cm cut-off (AUC 0.65 vs 0.60). Conclusion Using the maximal diameter, testicular ultrasound significantly miscalculated the pathologic dimensions of masses less than 2 cm compared to orchiectomy specimens. Volumetric measurements may better represent actual tumor sizes for SMTMs and may be a more useful measure for identifying those a higher risk for benign pathology, however, further studies are required.

  • Exploring the intersection of functional recurrence, patient-reported
           sexual function, and treatment satisfaction after anterior buccal mucosal
           graft urethroplasty
    • Abstract: Purpose To evaluate the interplay of stricture recurrence, sexual function, and treatment satisfaction after substitution urethroplasty. Methods Observational study of men undergoing 1-stage buccal mucosal graft urethroplasty for anterior urethral stricture between 2009 and 2016. Patients were dichotomized by self-reported treatment satisfaction. Sexual function was assessed by validated and non-validated patient-reported outcome measures. Functional recurrence was defined as symptomatic need of re-intervention. Bivariate analyses, Kaplan–Meier estimates, qualitative and quantitative analyses by uni- and multivariable regression were employed to evaluate the interplay of sexual function, functional recurrence, and treatment satisfaction. Results Of 534 men with bulbar (82%), penobulbar (11%), and penile strictures (7.3%), 451 (84%) were satisfied with the surgery. There were no differences in stricture location, previous treatment, graft length, or surgical technique between satisfied and unsatisfied patients (all p  ≥  0.2). Recurrence-free survival was 85% at a median follow-up of 33 mo and decreased significantly with each Likert item towards increasing dissatisfaction (p  <  0.001). Dissatisfied patients more often reported postoperative loss of rigidity, tumescence, reduced ejaculatory volume, ejaculatory pain, and reduced penile length (all p  ≤  0.042). In 83 dissatisfied men, functional recurrence (28%) and oral morbidity (20%) were the main drivers of dissatisfaction in qualitative analysis. Multivariable analyses revealed functional recurrence and impaired postoperative ejaculatory function as independent predictors of treatment dissatisfaction (all p  ≤  0.029) after adjusting for confounders. Conclusion We found an association of both functional success and sexual function with patient-reported treatment satisfaction after substitution urethroplasty. Such findings validate the clinical significance of defining the symptomatic need for re-intervention as an endpoint and underline the importance of further research evaluating sexual function before and after open urethral reconstruction.

  • Silicone-hydrocoated ureteral stents encrustation and biofilm formation
           after 3-week dwell time: results of a prospective randomized multicenter
           clinical study
    • Abstract: Objective To explore the risk of encrustation and biofilm formation for silicone ureteral stents compared to percuflex polymer stents, through a randomized multicenter study. Patients and methods Design, setting and participants: A Multicenter, prospective, randomized, single blind, comparative study of hydrocoated silicone stent (Coloplast Imajin® hydro) versus Percuflex™ Plus stent (Boston Scientific), in 141 patients treated by flexible URS for a kidney stone. The study had ethical committee approval in the respective hospitals. Outcome measurements and statistical analysis: Endpoints related to encrustation were biofilm formation and mineral encrustation after a period of 3-week indwelling time. They were evaluated at removal through a scoring scale of ureteral stents encrustation, infrared spectroscopy and optical microscopy of inner and outer surfaces of tips, angles and along the stent’s body. Comparison was performed using ANOVA. Results 119 stents were available after removal for analysis, 56 in the silicone and 63 in the Percuflex TM Plus group. Mean dwelling duration was 21.8 days for silicone, 22.1 days for PercuflexTM Plus. There was significantly more biofilm on Percuflex™ Plus compared to silicone (1.24 ± 0.08 vs 0.93 ± 0.09, p = 0.0021), and more mineral encrustation (1.22 ± 0.10 vs 0.78 ± 0.11, p = 0.0048), respectively. Conclusions This multicenter randomized study shows that silicone-hydrocoated stents are less prone to encrustation than PercuflexTM Plus after a 3-week dwelling period and confirms the low encrustation potential of silicone.

  • Five-alpha reductase inhibitors in men undergoing active surveillance for
           prostate cancer: impact on treatment and reclassification after 6 years
    • Abstract: Objectives To evaluate the impact of 5-alpha reductase inhibitors (5-ARIs) on definitive treatment (DT) and pathological progression (PP) in patients on active surveillance (AS) for prostate cancer. Methods We identified 361 consecutive patients, from an IRB-approved database, on AS for prostate cancer with minimum 2 years follow-up. Patients were grouped into two cohorts, those using 5-ARIs (5-ARI; n = 119) or not using 5-ARIs (no 5-ARI; n = 242). Primary and secondary endpoints were treatment-free survival (TFS) and PP-free survival (PPFS), which were evaluated by Kaplan–Meier analysis. Univariate and multivariable cox regression analysis were used to identify predictors for PP and DT. A p value < 0.05 was considered statistically significant. Results Baseline characteristics and the prostate biopsy rate were similar between the two groups. Median (range) follow-up was 5.7 (2.0–17.2) years. Five-year and 10-year TFS was 92% and 59% for the 5-ARI group versus 80% and 51% for the no 5-ARI group (p = 0.005), respectively. Five-year and 10-year PPFS was 77% and 41% for the 5-ARI group versus 70% and 32% for the no 5-ARI group (p = 0.04), respectively. Independent predictors for treatment and PP were not taking 5-ARIs (p = 0.005; p = 0.02), entry PSA > 2.5 ng/mL (p = 0.03; p = 0.01) and Gleason pattern 4 on initial biopsy (p < 0.001; p < 0.001), respectively. The main limitation is the retrospective study design. Conclusions 5-ARIs reduces reclassification and cross-over to treatment in men on active surveillance for prostate cancer. Further, taking 5-ARIs was an independent predictor for prostate cancer progression and definitive treatment.

  • The prognostic significance of lactate dehydrogenase levels in seminoma
           patients with advanced disease: an analysis by the Global Germ Cell Tumor
           Collaborative Group (G3)
    • Abstract: Purpose The prognostic significance of lactate dehydrogenase (LDH) in patients with metastatic seminoma is not defined. We investigated the prognostic impact of LDH levels prior to first-line systemic treatment and other clinical characteristics in this subset of patients. Methods Files from two registry studies and one single-institution database were analyzed retrospectively. Uni- and multivariate analyses were conducted to identify patient characteristics associated with recurrence free survival (RFS), overall survival (OS), and complete response rate (CRR). Results The dataset included 351 metastatic seminoma patients with a median follow-up of 5.36 years. Five-year RFS, OS and CRR were 82%, 89% and 52%, respectively. Explorative analysis revealed a cut-off LDH level of < 2.5 upper limit of normal (ULN) (n = 228) vs. ≥ 2.5 ULN (n = 123) to be associated with a significant difference concerning OS associated with 5-years OS rates of 93% vs. 83% (p = 0.001) which was confirmed in multivariate analysis (HR 2.87; p = 0.004). Furthermore, the cut-off LDH < 2.5 ULN vs. ≥ 2.5 ULN correlated with RFS and CRR associated with a 5-years RFS rate and CRR of 76% vs. 86% (p = 0.012) and 32% vs. 59% (p  ≤  0.001), respectively. Conclusions LDH levels correlate with treatment response and survival in metastatic seminoma patients and should be considered for their prognostic stratification.

  • Prognostic significance of total plasma cell-free DNA level and androgen
           receptor amplification in castration-resistant prostate cancer
    • Abstract: Purpose To investigate the prognostic significance of total cell-free DNA (cfDNA) level and androgen receptor amplification (AR-amp) in patients with castration-resistant prostate cancer (CRPC). Methods We retrospectively compared the total cfDNA level and AR-amp in 42 individuals without prostate cancer, 57 patients with localized prostate cancer without androgen-deprivation therapy (ADT), 97 patients with castration-sensitive prostate cancer (CSPC) with ADT, and 97 patients with CRPC. The association of these cfDNA biomarkers on disease status and overall survival was evaluated using Kaplan–Meier analysis and multivariable Cox regression analysis. Finally, a simple risk model was developed including total cfDNA and AR-amp to predict poor prognosis. Results The median total cfDNA level and AR-amp in patients with CRPC was 387 pg/μL and 1.07 copies, respectively. The total cfDNA levels and AR-amp were significantly higher in the patients with CRPC than in individuals without prostate cancer, patients with localized prostate cancer without ADT, and patients with CSPC with ADT. Total cfDNA-high (> 600 pg/μL) and AR-amp-high (> 1.26 copies) were significantly associated with poor overall survival. Multivariable Cox regression analysis showed cfDNA-high and AR-amp-high were significantly associated with poor overall survival in patients with CRPC. We developed a risk model using cfDNA-high (score 1) and AR-amp-high (score 1). The risk score 1–2 was significantly associated with worse overall survival than score 0. Conclusion Total cfDNA level and AR-amp are potential biomarkers for poor prognosis in patients with CRPC.

  • Evolving trends in peri-operative management of pediatric ureteropelvic
           junction obstruction: working towards quicker recovery and day surgery
    • Abstract: Objective To describe the evolution of practice patterns for pediatric pyeloplasty and determine how these changes have impacted length of stay (LOS), reoperation rates and return emergency department (ER) visits. Methods We reviewed our pyeloplasty database from 2008 to 2020 at a quaternary pediatric referral center and we included children 0–18 years undergoing pyeloplasty. Variables captured included: age, sex, baseline and follow-up anteroposterior diameter (APD) and differential renal function (DRF). We also collected data on the use of drains, catheters and/or stents, nausea and vomiting prophylaxis, opioids, regional anesthesia, and non-opioid analgesia. Outcomes were LOS, reoperation rates and ER visits. Results A total of 554 patients (565 kidneys) were included. Reoperation rate was 7%, redo rate 4% and ER visits 17%. There was a trend towards less opioids, indwelling catheters and internal stents and increasing non-opioid analgesia, externalized stents, and regional anesthesia during the study period. Same-day discharge (SDD) was possible for 88 (16%) children with no differences in reoperation or readmission rates between SDD and admitted (ADM). There was a difference in ER visits (21 [24%] vs. 26 [6%]; p = 0.04) for SDD vs. ADM, respectively. On multivariate analysis, the only predictor of ER visits was younger age. Patients < 7 months were more likely to present to ER (15/41; 37% vs. 6/47, 13%; p = 0.009). Multivariate analysis determined indwelling catheters and opioids were associated with ADM while dexamethasone and ketorolac with SDD. Conclusion Progressive changes in care have contributed to a shorter LOS and increasing rates of SDD for pyeloplasty patients. SDD appears to be feasible and does not result in higher complication rates. These data support the development of a pediatric pyeloplasty ERAS protocol to maximize quicker recovery and foster SDD as a goal.

  • Active surveillance for prostate cancer: selection criteria, guidelines,
           and outcomes
    • Abstract: Introduction Active surveillance (AS) has been widely adopted for the management of men with low-risk prostate cancer. However, there is still a lack of consensus surrounding the optimal approach for monitoring men in AS protocols. While conservative management aims to reduce the burden of invasive testing without compromising oncological safety, inadequate assessment can result in misclassification and unintended over- or undertreatment, leading to increased patient morbidity, cost, and undue risk. No universally accepted AS protocol exists, although numerous strategies have been developed in an attempt to optimize the management of clinically localized disease. Variability in selection criteria, reclassification, triggers for definitive treatment, and follow-up exists between guidelines and institutions for AS. In this review, we summarize the landscape of AS by providing an overview of the existing AS protocols, guidelines, and their published outcomes. Methods A comprehensive electronic search was performed to identify representative studies and guidelines pertaining to AS selection criteria and outcomes. Conclusion While AS is a safe and increasingly utilized treatment modality for lower-risk forms of PCa, ongoing research is needed to optimize patient selection as well as surveillance protocols along with improved implementation across practices. Further, assessment of companion risk assessment tools, such as mpMRI and tissue-based biomarkers, is also needed and will require rigorous prospective study.

  • A novel prediction model for the completion of six cycles of radium-223
           treatment and survival in patients with metastatic castration-resistant
           prostate cancer
    • Abstract: Purpose We evaluated the predictive factors for completion of all six cycles of radium-223 (Ra-223) treatment in patients with metastatic castration-resistant prostate cancer (mCRPC). We also developed a novel prediction model for Ra-223 treatment completion using these predictors. Methods We retrospectively reviewed data from 122 patients with mCRPC who were treated with Ra-223. The predictive factors for the completion of six cycles of Ra-223 treatment were evaluated. Statistically significant predictive factors were then used to develop a prediction model for treatment completion. Finally, using this prediction model, we classified the overall survival (OS) of the entire cohort into three groups. Results We identified three significant variables as the predictive factors for treatment completion: baseline alkaline phosphatase (ALP) level, baseline hemoglobin (Hb) level, and baseline pain. The three groups generated using the prediction model were: group 1 (patients with three predictive factors, i.e., ALP < median, Hb ≥ median, and no pain), group 2 (patients with one to two predictive factors), and group 3 (patients without any predictive factors). The treatment completion rates differed between the three groups significantly. Furthermore, the OS also differed among the groups significantly. Conclusion Our study suggested that the baseline ALP level, baseline Hb level, and baseline pain were the predictive factors of completion of all six cycles of Ra-223 treatment in patients with mCRPC. Our prediction model consisting of these factors could predict not only the completion of Ra-223 treatment, but also the post-treatment survival. This model can thus be useful for selection of patients for Ra-223 treatment.

  • Predictive value of De Ritis ratio in metastatic renal cell carcinoma
           treated with tyrosine-kinase inhibitors
    • Abstract: Background Predictive markers can help tailor treatment to the individual in metastatic renal cell carcinoma (mRCC). De Ritis ratio (DRR) is associated with oncologic outcomes in various solid tumors. Objective To assess the value of DRR in prognosticating survival in mRCC patients treated with tyrosine-kinase inhibitors (TKI). Methods Overall, 220 mRCC patients treated with TKI first-line therapy were analyzed. An optimal cut-off point for DRR was determined with Youden’s J. We used multiple strata for DRR, performed descriptive, Kaplan–Meier and multivariable Cox-regression analyses to assess associations of DRR with progression-free (PFS) and overall survival (OS). Results Patients above the optimal cut-off point for DRR of ≥ 1.58 had fewer liver metastases (p = 0.01). There was no difference in PFS (p > 0.05) between DRR groups. DRR above the median of 1.08 (HR 1.42; p = 0.03), DRR ≥ 1.1(HR 1.44; p = 0.02), ≥ 1.8 (HR 1.56; p = 0.03), ≥ 1.9 (HR 1.59; p = 0.02) and ≥ 2.0 (HR 1.63; p = 0.047) were associated with worse OS. These associations did not remain after multivariable adjustment. In the intermediate MSKCC group, DRR was associated with inferior OS at cut-offs ≥ 1.0 (HR 1.78; p = 0.02), ≥ 1.1 (HR 1.81; p = 0.01) and above median (HR 1.88; p = 0.007) in multivariable analyses. In patients with clear-cell histology, DRR above median (HR 1.54; p = 0.029) and DRR ≥ 1.1 (HR 1.53; p = 0.029) were associated with OS in multivariable analyses. Conclusion There was no independent association between DRR and survival of mRCC patients treated with TKI in the entire cohort. However, OS of patients with intermediate risk and clear-cell histology were affected by DRR. DRR could be used for tailored decision-making in these subgroups.

  • Percutaneous nephrolithotomy with ultrasound-assisted puncture: does the
           technique reduce dependence on fluoroscopic ionizing radiation'
    • Abstract: Purpose The ultrasound-guided (US) puncture in percutaneous nephrolithotomy (PCNL) has demonstrated advantages over traditional fluoroscopy access. The aim of this study was to demonstrate the reduction of fluoroscopy time using this technique during PCNL as the surgeon gained experience. Methods Transversal study performed on 30 consecutive patients undergoing PCNL from March to November 2019. All punctures were performed with US guidance. The patients were divided into 2 groups of 15 each according to the chronological order of the intervention. Demographic data, preoperative parameters, puncture time, fluoroscopy time, stone-free rate and complications were analyzed. Results The time of fluoroscopy was considerably reduced as the experience in the number of cases increased, reducing from 83.09 ± 47.8 s in group 1 to 22.8 ± 10.3 s in group 2 (p < 0.01), the time required to perform the puncture was reduced of 108.1 ± 68.9 s in group 1, to 92.6 ± 94.7 s in group 2 (p < 0.67). Stone free rate of 83.3% was obtained globally. Conclusion US percutaneous renal access is safe and reproducible technique; the main advantage is to reduce exposure to radiation without compromising clinical results and has a short learning curve for urologists with prior experience in PCNL.

  • The prognostic value of fat invasion and tumor expansion in the hilar
           veins in pT3a renal cell carcinoma
    • Abstract: Purpose The 7th TNM classification summarizes renal cell carcinoma (RCC) with perirenal (PFI) and/or sinus fat invasion (SFI) as well as hilar vein involvement (RVI) as pT3a tumors. In this study, we aimed to determine the prognostic value of fat invasion (FI) in the different compartments and RVI for medium-term cancer-specific-survival (CSS) in pT3a RCC. Materials and methods Patients with pT3a RCC were identified using an institutional database. All original pathological reports were reclassified according to the 7th TNM edition. The prognostic value of FI as well as divided into PFI, SFI, combined PFI + SFI, and RVI for CSS was assessed using univariate and multivariate Cox-regression analysis. Survival was estimated using the Kaplan–Meier method. Results Median follow-up in 184 pT3a tumors was 38 months. FI was detectable in 153 patients (32.7% PFI, 45.1% SFI, 22.2% PFI + SFI), 31 patients showed RVI alone. Combined PFI + SFI increased the risk of cancer-related death compared to PFI (HR 3.11, p < 0.01), SFI (HR 1.84, p = 0.023) or sole RVI (HR 2.12, p = 0.025). In multivariate analysis, a combined PFI + SFI vs. PFI or SFI as the only compartment involved was confirmed as independent prognostic factor (HR 1.83, p = 0.029). Patients with FI and simultaneous RVI had significantly shorter CSS (HR 2.63, p < 0.01). In an unweighted model, the difference between patients with combined PFI + SFI and RVI and those with PFI alone was highest (HR 4.01, p = 0.029). Conclusions These results underline the subdivision of pT3a RCC depending on the location of FI and RVI for patient stratification.

  • Early urinary continence recovery following retzius-sparing
           robotic-assistant radical prostatectomy with suprapubic catheter: a
           short-term follow-up outcome
    • Abstract: Objective To evaluate the recovery of early urinary continence in patients with prostate cancer using a suprapubic catheter during Retzius-sparing robotic-assistant laparoscopic prostatectomy. Patients and methods From January 2018 to January 2019, 223 patients diagnosed with prostate cancer who underwent Retzius-sparing robotic-assistant laparoscopic prostatectomy in Diakonie Klinikum Stuttgart were involved in our study. From January 2018 to June 2018, patients (112 cases) only had an indwelling urinary catheter during Retzius-sparing robotic-assistant laparoscopic prostatectomy, while from July 2018 to January 2019, patients (111 cases) were offered an extra suprapubic catheter during operation. The recovery of early urinary continence of patients was mainly investigated one month later. Results The overall early urinary continence rate was 81.61%. Patients with suprapubic catheter had better urinary control results, compared to patients with only indwelling urinary catheter (87.39% vs 75.89%, p = 0.027). In addition, International Prostate Symptom Score and irritative subscore in patients with good urinary control were significantly lower than that in patients with urinary incontinence. Suprapubic catheter insertion (OR 0.395; 95% CI 0.190–0.821) and advanced pathological tumor stage (T3a–T4) (OR 2.061; 95% CI 1.008–4.217) were two independent influencing factors for early urinary continence recovery in patients who underwent Retzius-sparing robotic-assistant laparoscopic prostatectomy through multivariate logistic regression analysis. Conclusion Suprapubic catheter insertion may be helpful for early urinary continence recovery in patients with Retzius-sparing Robotic-assistant laparoscopic prostatectomy. Advanced pathological tumor stage (T3a–T4) before Retzius-sparing robotic-assistant laparoscopic prostatectomy might be associated with poor urinary control.

  • Outcome after resection of occult and non-occult lymph node metastases at
           the time of nephrectomy
    • Abstract: Purpose There is sparse evidence on outcomes of resected occult LN metastases at the time of nephrectomy (synchronous disease). We sought to analyse a large international cohort of patients and to identify clinico-pathological predictors of long-term survival. Materials and methods We collected data of consecutive patients who underwent nephrectomy and LND for Tany cN0-1pN1 and cM0-1 RCC at 7 referral centres between 1988 and 2019. Patients were stratified into four clinico-pathological groups: (1) cN0cM0-pN1, (2) cN1cM0-pN1(limited, 1–3 positive nodes), (3) cN1cM0-pN1(extensive, > 3 positive nodes), and (4) cM1-pN1. Overall survival (OS) was estimated using the Kaplan–Meier method, and associations with all-cause mortality (ACM) were evaluated using Cox models with multiple imputations. Results Of the 4370 patients with LND, 292 patients with pN1 disease were analysed. Median follow-up was 62 months, during which 171 patients died. Median OS was 21 months (95% CI 17–30 months) and the 5-year OS rate was 24% (95% CI 18–31%). Patients with cN0cM0-pN1 disease had a median OS of 57 months and a 5-year OS rate of 43%. 5-year OS (median OS) decreased to 29% (33 months) in cN1cM0-pN1(limited) and to 23% (23 months) in cN1cM0-pN1(extensive) patients. Those with cM1-pN1 disease had the worst prognosis, with a 5-year OS rate of 13% (9 months). On multivariable analysis, age (p = 0.034), tumour size (p = 0.02), grade (p = 0.02) and clinico-pathological group (p < 0.05) were significant predictors of ACM. Conclusion Depending on clinico-pathological group, grade and tumour size, 5-year survival of patients with LN metastases varies from 13 to 43%. Patients with resected occult lymph node involvement (cN0/pN1 cM0) have the best prognosis with a considerable chance of long-term survival.
