Background: The European Association of Urology (EAU) recommends discussing upfront radical cystectomy for all patients with very high risk (VHR) non-muscle-invasive bladder carcinoma (NMIBC), but the role of bacillus Calmette-Guérin (BCG) treatment remains controversial.

Objective: To analyze oncological outcomes in VHR NMIBC patients (EAU risk groups) treated with adequate BCG.

Clinical Usefulness of Prostate-specific Membrane Antigen-ligand Positron Emission Tomography/Computed Tomography for the Detection of Prostate Cancer Biochemical Recurrence after Primary Radiation Therapy in Patients with Prostate-specific Antigen Below the Phoenix Threshold: Systematic Review and Meta-analysis.

Aims: After primary radiotherapy, biochemical recurrence is defined according to the Phoenix criteria as a prostate-specific antigen (PSA) value >2 ng/ml relative to the nadir. Several studies have shown that prostate-specific membrane antigen (PSMA)-ligand positron emission tomography/computed tomography (PET/CT) can help in detecting recurrence in patients with low PSA values. This study aimed to assess the detection rate and patterns of PSMA-ligand PET/CT uptake in patients with suspected biochemical recurrence after primary radiotherapy and with PSA levels below the Phoenix threshold.

Primary testicular lymphoma: Clinical characteristics and oncological outcomes.

Background: Primary testicular lymphoma (PTL) is a rare testicular malignancy, despite being considered the most common testicular tumor in patients older than 60 years. Primary testicular lymphoma represents only 1%-9% of testicular neoplasms. Few studies have been published regarding its clinical features and management.

Is extracorporeal lithotripsy a first-line treatment for urinary stones today?

Objective: To evaluate the efficacy and complications of extracorporeal lithotripsy (SWL) as a first-line treatment for renal and ureteral stones METHODS: Retrospective and observational study of all the patients treated with lithotripsy in a third level center between January 2014 and January 2021; characteristics of the patients, the stones, complications and results of SWL is recollected. Multivariate logistic regression of the factors associated with stone size reduction was performed. A statistical analysis of the factors associated with additional treatment after SWL and factors associated with complications is also executed.

Schwannoma of the seminal vesicle: Case report and review of the literature.

Seminal vesicles can be affected by tumours originating in other locations. However, primary tumours of the seminal vesicle are extremely rare, with less than 100 cases reported in literature. Seminal vesicle adenocarcinoma is the most common type, but there are also other malign lesions.

Extracorporeal shock wave lithotripsy for lower calyx stones: predicting treatment success.

Introduction: The use of extracorporeal shock wave lithotripsy (ESWL) for lower calyx stones is associated with a high rate of residual fragments. Our aim is to analyse the effectiveness and complications of ESWL for lower calyx stones.

Methods: Retrospective review of patients with lower renal calyx stones treated with ESWL between January-2014 and December-2020.

Vascular closure devices in living-donor nephrectomy: a much-needed systematic review and meta-analysis focusing on safety.

Objective: To assess the safety of vascular closure devices in living-donor nephrectomy (LDN), as staplers and non-transfixion techniques (polymer locking and metal clips) are the methods employed to secure the renal vessels during laparoscopic and robotic LDN, but the use of clips has come into question since the United States Food and Drug Administration and manufacturers issued a contraindication.

Methods: A systematic review and meta-analysis were conducted to assess the safety of vascular closure devices (International Prospective Register of Systematic Reviews [PROSPERO] registration: CRD42022364349). The PubMed, Scopus, the Excerpta Medica dataBASE (EMBASE), and the Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) databases were searched in September 2022.

How has the COVID-19 pandemic influenced prostate cancer?-a tertiary single-centre analysis of oncological results, diagnosis and treatment times.

Background: The coronavirus disease 2019 (COVID-19) pandemic has affected care for diseases like cancer. The aim was to evaluate the impact of COVID-19 on waiting times for diagnosis and treatment of prostate cancer (PC), as well as the possible effect on the treatment results in PC patients undergoing radical prostatectomy.

Methods: We compared the results of 497 patients who underwent biopsy prior to the COVID-19 pandemic (1 January-31 December 2019) with those of 290 patients biopsied during the COVID-19 pandemic (1 January-31 December 2020).

Lessons learned after the disruption caused by COVID-19 in the management of urolithiasis: An example of adaptation in a high-volume center.

Background: The aim was to determine the impact of COVID-19 pandemic on urolithiasis presentation and management.

Methods: In this retrospective study, we comparatively evaluated urgent and elective procedures due to urolithiasis during the early eight months of the COVID-19 pandemic (March 1, 2020, to October 31, 2020) compared to the same period a year before, and between waves. The student's t-test, chi-square test, Mann-Whitney U test and Fisher's exact test were used to compare the patients' characteristics and outcomes between the two periods and waves.

Medicines in exceptional circumstances for solid tumours: focusing on evidence, effectiveness, and toxicity profiles.

Objective: To analyse the applications for drugs in special situations (compassionate use, off-label use and foreign drugs) for solid  tumours, and to assess the level of evidence supporting these applications, as  well as the effectiveness and safety of most frequent drugs.

Kidney Autotransplantation and Orthotopic Kidney Transplantation: Two Different Approaches for Complex Cases.

Introduction: Transplantation surgery teams often have to face complex cases. In certain circumstances, such as occlusion of the iliac vessels or prior pelvic surgery, heterotopic kidney transplantation may not be feasible and orthotopic kidney transplantation (OKT) could be a good alternative. Kidney autotransplantation (KAT) has been described as a potential treatment for complex renovascular, ureteral, or neoplastic conditions.

Kidney Autotransplantation in the Management of Residual Retroperitoneal Mass in a Germ Cell Tumor.

The main indication for kidney autotransplantation is ureteric disease, although it is also performed to treat renovascular diseases or neoplasms, such as complex intrasinusal kidney tumors or in patients with a solitary kidney. Only a few cases of kidney autotransplantation in the context of resection of complex retroperitoneal masses have been reported in the literature. CASE PRESENTATION: We report the case of a 26-year-old man with history of nonseminomatous germ cell tumor who had undergone a left radical orchiectomy 3 months earlier.
