    Abstract Introduction and aims: The optimal approach for nephroureterectomy in patients with suspected UTUC remains a point of debate. In this review, we compare the oncological outcomes of robotic nephroureterectomy (RNU) with open (ONU) or laparoscopic nephroureterectomy (LNU).
    Methods: All randomized trials and observational studies comparing RNU with ONU and/or LNU for suspected non-metastatic UTUC are included in this review. The systematic review was performed in accordance with the Cochrane Guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The primary outcome measures were overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), and intravesical recurrence-free survival (IV-RFS). The secondary outcome measures were the lymph node dissection (LND) rates, positive margin rates, and the proportion of patients receiving bladder intravesical chemotherapy.
    Results: We identified 8172 references through our electronic searches and 8 studies through manual searching. A total of 15 studies met the inclusion criteria. The total number of patients in the review was 18,964. RNU had superior OS compared to LNU (HR: 0.81 (95% CI: 0.71, 0.93),
    Conclusion: RNU offers comparable oncological efficacy to ONU, except for intravesical recurrence-free survival (IV-RFS). RNU has fewer positive surgical margin rates compared to ONU in well-balanced studies. RNU appears to outperform LNU for certain oncological parameters, such as OS and the proportion of patients who receive lymph node dissections. The quality of evidence comparing surgical techniques for UTUC has remained poor in the last decade.

    Abstract Prostate cancer remains the most common malignancy diagnosed in men andis the third leading cause of cancer death among men in the United States and Europe.On this basis, it is anticipated by many that the rates of prostate cancer mortality may rise in the years to come. As a result, a number of new challenges have emerged in prostate cancer, forcing urologists to consider new paradigms in the disease management: both to improve methods of detection and to be more effective in managing the likely increasing numbers of men with advanced disease.

    Abstract Introduction: Kidney perfusion on CT is an encouraging surrogate for renal scintigraphy in assessing renal function. However, data on dynamic volumetric CT in patients with kidney obstruction is lacking. Thus, the aim of this study is to determine the feasibility of CT-based renal perfusion using a dynamic volume to assess renal hemodynamics at different degrees and durations of obstruction.
    Materials and methods: We included patients with unilateral kidney obstruction in our single-center, prospective study. The patients were divided into three groups. Patients without dilatation of the pelvicalyceal system (PCS) and normal parenchyma thickness were included into Group 1; patients with PCS dilatation and parenchyma thickness 1.8-2.4 cm-into Group 2; and patients with ureteropyelocalicoectasia and parenchyma thickness less than 1.8 cm-into Group 3.
    Results: Total of 56 patients were enrolled. In Group 1 mean values of cortical and medullar arterial blood flow, blood volume, and extraction fraction were within the normal range. Changes in contralateral kidney were not determined. Patients from Group 2 showed significant differences in blood flow parameters in the cortical and medulla of the obstructed kidney. No changes in perfusion values in the contralateral kidney was observed. In patients from Group 3 there was a marked decrease in perfusion on the side of obstruction compared to Group 2, indicating that the degree of expansion of the PCS directly correlates with the change in blood flow. However, in the contralateral kidney, these indicators exceeded the normal values of perfusion.
    Conclusion: CT perfusion allows to objectively assess changes in blood flow in the setting of renal obstruction. The degree of obstruction directly affects the measured rate of blood flow.

    Title translation Analysis of renal tumor size as a predictive factor of oncological aggressiveness.
    Abstract Introduction: The increased incidenceof diagnosis of kidney tumours has driveninvestigation in the area. It is known that the risk ofmalignancy is correlated with tumour size, but thereare still no specific and objective parameters to characterizethe degree of aggressiveness and to be ableto guide a treatment reliably. OBJECTIVE: To identify the relationship betweenrenal tumour size and the incidence of tumour aggressivecharacteristics.
    Patients and methods: A retrospective analysisof our series of renal cancers operated between 1998and 2018 was performed. The specific and cumulativeincidence of aggressive characteristics was studied.The following where considered as aggressive characteristics:Presence of sarcomatoid or epidermoiddifferentiation, tumour necrosis, stage pT3-4, histologicalhigh grade (3-4) and the presence of histologicalaggressive variants.
    Results: A total of 651 patients that had undergonerenal mass surgery were analysed. In tumours below2 cm the appearance of aggressive characteristicsoccurred in less than 5%. For renal masses greaterthan 2 cm, each centimetre increase correlated with arise in cumulative incidence of 2-3% for each characteristicstudied.
    Conclusions: In tumours below 2cm and patientswith significant comorbidities active surveillance maybe a reliable alternative to surgery.
