Introduction: The concept of thermal safety distance upon laser activation has been recently introduced. We aimed to compare the thermal safety distance of Ho: YAG and thulium fiber laser (TFL) activation at different setups using an in vitro model.
Methods: The experimental setup used a glass pipette with an open roof bulb in a 37 °C water bath to simulate a renal calyx.
Introduction: Informative censoring (IC) is a statistical bias that occurs when there is an imbalance in the dropout rate among study arms and this imbalance is not random, but can be ascribed to information that is not accounted for. Studies on trimodal therapy (TMT) versus radical cystectomy (RC) yielded conflicting results. We conducted a meta-analysis to assess the potential impact of informative censoring in influencing study outcomes.

Cellular senescence is a state of stable cell-cycle arrest induced by various intrinsic and extrinsic stressors, serving as a protective mechanism to prevent the proliferation of damaged cells. While this process is crucial for tissue homeostasis and tumor suppression, the progressive accumulation of senescent cells (SnCs) over time is implicated in age-related pathologies, including immune dysfunction and cancer. In oncology, senescence plays a paradoxical role: it can inhibit tumor development by halting the growth of potentially malignant cells, yet it may also facilitate tumor progression through the senescence-associated secretory phenotype (SASP).

The concept of thermal dose, which accounts for both temperature and exposure duration, provides a more nuanced understanding of tissue tolerance than fixed temperature thresholds, considering both the magnitude of the temperature increase and the length of exposure to each specific temperature. The concept of a thermal safety distance defines the spatial extent of potential damage, supporting safe power limits of 10 W in the ureter and 20 W in the kidney.

Background And Objective: Extended pelvic lymph node dissection (ePLND) is recommended in selected radical prostatectomy (RP) prostate cancer (PCa) patients for staging purposes. We aim to externally validate available tools to predict lymph node invasion (LNI) in men with negative preoperative prostate-specific membrane antigen positron emission tomography (miN0).
Methods: Overall, 282 intermediate- to high-risk PCa patients with miN0 disease undergoing RP and ePLND at ten centers between 2016 and 2023 were identified.
Objectives: Survival outcomes of patients with metastatic urothelial carcinoma (mUC) are still suboptimal and strategies to enhance response to immune-oncology (IO) compounds are under scrutiny. In preclinical studies, it has been demonstrated that antihistamines may reverse macrophage immunosuppression, reactivate T cell cytotoxicity, and enhance the immunotherapy response. We aimed to evaluate the role of concomitant antihistamines administration on oncological outcomes among patients with mUC.

Purpose: The utility of a pelvic drain (PD) after robot-assisted radical prostatectomy (RARP) has been recently questioned. We investigated the impact of discontinuing PD placement after RARP on complications, pain, environmental benefits, and cost savings.
Methods: We identified 1,199 patients who underwent RARP with or without extended pelvic lymph node dissection from 2016 to 2023 at a referral center.
Purpose: To examine temporal-spatial distribution of heat generated upon laser activation in a bench model of renal calyx. To establish reference values for a safety distance between the laser fiber and healthy tissue during laser lithotripsy.
Methods: We developed an in-vitro experimental setup employing a glass pipette and laser activation under various intra-operative parameters, such as power and presence of irrigation.
Background: Assessing urinary symptoms poses a complex challenge for primary care practitioners. In evaluating urological function, authors' approach involves constructing an urological age through the analysis of laboratory parameters and indicators of the urinary system.
Methods: Based on the National Health and Nutrition Examination Survey (NHANES), urological laboratory tests and age-related symptoms were included in the development of urological age (UA) and urological age acceleration (UAA) through the Klemera Doubal method.
Background: Acute kidney disease (AKD) is a recently described syndrome consisting of kidney function abnormalities lasting less than 3 months. Little is known regarding AKD following ureteroscopy (URS) and laser lithotripsy.
Objective: To evaluate the occurrence and evolution of AKD in stone patients treated with URS.
Purpose: We assessed the impact of the one-year endourological society fellowship program (ESFP) on the achievement of optimal surgical outcomes (OSO) in stone patients treated with ureteroscopy (URS).
Materials And Methods: We identified 303 stone patients treated with URS from January 2018 to June 2022 by five experienced surgeons (ES). Of those, two attended ESFP.
Background And Objective: Pathological features in non-muscle-invasive bladder cancer specimens are pivotal in determining correct patients' therapeutic management.

Introduction: Prostate-specific membrane antigen radioguided surgery (PSMA-RGS) might identify lymph node invasion (LNI) in prostate cancer (PCa) patients undergoing extended pelvic lymph node dissection (ePLND). The optimal target-to-background (TtB) ratio to define RGS positivity is still unknown.
Materials & Methods: Ad interim analyses which focused on 30 patients with available pathological information were conducted.
Purpose Of Review: The implementation of PET with prostate-specific membrane antigen (PSMA) tracer as primary staging tool occurred recently. Since its introduction, a novel category of patients emerged, with negative staging at conventional imaging, and positive molecular imaging. Local treatment in these patients might be associated with improved oncological outcomes when combined with systemic therapy.
View Article and Find Full Text PDFBackground: To assess the variation of multiparametric magnetic resonance imaging (mpMRI) positive predictive value (PPV) according to each patient's risk of clinically significant prostate cancer (csPCa) based exclusively on clinical factors.
Methods: We evaluated 999 patients with positive mpMRI (PI-RADS ≥ 3) receiving targeted (TBx) plus systematic prostate biopsy. We built a multivariable logistic regression analysis (MVA) using clinical risk factors to calculate the individual patients' risk of harboring csPCa at TBx.
Background: A significant proportion of patients with positive multiparametric magnetic resonance imaging (mpMRI; Prostate Imaging-Reporting and Data System [PI-RADS] scores of 3-5) have negative biopsy results.
Objective: To systematically assess all prostate-specific antigen density (PSAD) values and identify an appropriate cutoff for identification of patients with positive mpMRI who could potentially avoid biopsy on the basis of their PI-RADS score.
Design, Setting, And Participants: The study included a cohort of 1341 patients with positive mpMRI who underwent combined targeted and systematic biopsies.
Background: De novo oligometastatic prostate cancer (omPCa) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) is a new disease entity and its optimal management remains unknown.
Objective: To analyze the outcomes of patients treated with cytoreductive radical prostatectomy (cRP) for omPCa on PSMA-PET.
Design, Setting, And Participants: Overall, 116 patients treated with cRP at 13 European centers were identified.
Background: The role of local therapies including radical prostatectomy (RP) in prostate cancer (PCa) patients with clinical lymphadenopathies on prostate-specific membrane antigen (PSMA) positron emission tomography/computerized tomography (PET/CT) has scarcely been explored. Limited data are available to identify men who would benefit from RP; on the contrary, those more likely to benefit already have systemic disease.
Objective: We aimed to assess the predictors of prostate-specific antigen (PSA) persistence in surgically managed PCa patients with lymphadenopathies on a PSMA PET/CT scan by integrating clinical, magnetic resonance imaging (MRI), and PSMA PET/CT parameters.
Introduction: Several preclinical studies about a novel pulsed-thulium:yttrium-aluminum-garnet (p-Tm:YAG) device have been published, demonstrating its possible clinical relevance.
Methods: We systematically reviewed the reality and expectations for this new p-Tm:YAG technology. A PubMed, Scopus and Embase search were performed.
Objective: To investigate the association between immune-related adverse events (irAEs) and oncological outcomes in patients with advanced urothelial cancer receiving immune checkpoint inhibitors (ICIs), and whether the administration of systemic corticosteroids diminishes therapeutic impact.
Patients And Methods: The association between irAEs occurrence and clinical progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS) was tested by means of multivariable Cox or competing-risks regression, when appropriate. Patients experiencing irAEs were further stratified based on systemic corticosteroids administration.

Purpose: To investigate the feasibility, safety, and oncological outcomes of Radical Prostatectomy (RP; either Robot-Assisted [RARP] or Open RP [ORP]) in oligometastatic prostate cancer (omPCa). Additionally, we assessed whether there was an added benefit of metastasis-directed therapy (MDT) in these patients in the adjuvant setting.
Methods: Overall, 68 patients with omPCa (≤ 5 skeletal lesions at conventional imaging) treated with RP and pelvic lymph node dissection between 2006 and 2022 were included.
Background: Although the therapeutic role of extended pelvic lymph node dissection (ePLND) in patients with prostate cancer (PCa) is still under debate, this procedure is recommended for staging purposes in selected cases. Nomograms for predicting lymph node invasion (LNI) do not account for prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging, which is characterized by a high negative predictive value for nodal metastases.
Objective: To externally validate models predicting LNI in patients with miN0M0 PCa at PSMA PET and to develop a novel tool in this setting.
Unlabelled: The PROpel trial assessed the combination of olaparib + abiraterone acetate (AA) plus prednisone and androgen deprivation therapy (ADT) versus AA plus prednisone and ADT alone as first-line treatment for metastatic castration-resistant prostate cancer (mCPRP). To contextualize the progression free survival (PFS) benefit in PROpel, we performed a systematic review and quasi-individual patient data network meta-analysis on randomized controlled trials of first-line hormonal treatments for mCPRC. Meta-analysis was performed for the PROpel control arm and PREVAIL (enzalutamide) and COU-AA-302 (AA) treatment arms.
