Purpose: To investigate the detection and predictors of prostate cancer (PCA) and clinically significant prostate cancer (csPCA) in patients with positive multiparametric MRI (mpMRI) followed by a negative MRI - guided target biopsy (TB) and systematic biopsy (SB).

Materials And Methods: This retrospective multicenter study included 694 patients from 10 tertiary referral centers with an initial positive mpMRI (PI-RADS ≥ 3) and negative results on both MRI-TB and SB. Patients were classified into three groups based on follow-up: Group 1 (prostate re-biopsy without new mpMRI), Group 2 (standardized second prostate mpMRI and subsequent re-biopsy), and Group 3 (follow-up with mpMRIs and biopsy based on clinical and radiological triggers).

Background And Objective: The depth of the prostate-specific antigen (PSA) decline after androgen receptor pathway inhibitor (ARPI) treatment combined with androgen deprivation therapy for patients with metastatic hormone-sensitive prostate cancer (mHSPC) may affect prognosis. The primary objective in our study was the correlation between the PSA response at 3 mo and radiologic progression-free survival (rPFS) at 24 mo. Three groups were defined according to the PSA decline: complete response (PSA ≤0.

Article Synopsis
  • The study looks at how the size of the prostate affects patients’ recovery and symptoms after a surgery called RASP, which helps treat an enlarged prostate (BPH).
  • They reviewed 25 articles and found that patients with smaller prostates had worse symptoms before surgery but improved more after, while those with larger prostates still had some moderate symptoms.
  • The researchers concluded that RASP is a safe and effective surgery for treating BPH, but more studies are needed to understand how prostate size influences the results.

Article Synopsis
  • * In healthcare, it can help with things like training surgeons using virtual worlds, planning surgeries with 3D models, and guiding surgeons during operations.
  • * There are exciting possibilities ahead, like better patient care through monitoring and education, but we need to solve issues with data security before diving in fully.

Objective: To investigate the impact of ageing on survival outcomes in Bacillus Calmette-Guérin (BCG) treated non-muscle invasive bladder cancer (NMIBC) patients and its synergy with adequate BCG treatment.

Method: Patients with NMIBC who received BCG treatment from 2001 to 2020 were divided into group 1 (< = 70 years) and group 2 (> 70 years). Overall Survival (OS), Cancer-Specific Survival (CSS), Recurrence-Free Survival (RFS), and Progression-Free Survival (PFS) were analyzed using the Kaplan-Meier method.

Article Synopsis
  • European laparoscopic urological skills (LUSs2) curriculum is being developed to fill the gap in intermediate and advanced training for laparoscopic surgical procedures in urology, promoting uniformity and proficiency among practitioners.
  • A Delphi survey with international experts helped create this curriculum; it achieved consensus on 85% of the evaluated statements regarding crucial laparoscopic procedures.
  • The new curriculum aims to enhance surgical education standards, improve surgical skills, and ultimately provide better patient care, although some limitations and potential biases in the process were noted.

Introduction: The aim of this study is to compare outcomes of SRP (salvage radical prostatectomy) with SCAP (salvage cryoablation of the prostate) in local radio-recurrent PCa (prostate cancer) patients.

Materials And Methods: A retrospective analysis of a multicentric European Society of Uro-technology (ESUT) database was performed. Data on patients with local recurrent PCa after radiotherapy who underwent salvage treatment were collected.

Objective: To investigate the influence of statins on the survival outcomes of patients with non-muscle-invasive bladder cancer (NMIBC) treated with adjuvant intravesical bacille Calmette-Guérin (BCG) immunotherapy.

Patients And Methods: A retrospective cohort of consecutive patients with NMIBC who received intravesical BCG therapy from 2001 to 2020 and statins prescription were identified. Overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and progression-free survival (PFS) were analysed between the Statins Group vs No-Statins Group using Kaplan-Meier method and multivariable Cox regression.

Article Synopsis
  • - PIONEER is a European initiative that combines the efforts of 34 organizations across 9 countries to enhance prostate cancer screening, diagnosis, and treatment using big data analytics.
  • - The project has created a comprehensive platform that integrates various data sources, helping to respond to critical research questions and improve understanding of prostate cancer management at different stages.
  • - Despite successes, challenges with real-world data persist, necessitating ongoing collaboration and knowledge sharing, which PIONEER aims to support as part of the UroEvidenceHub initiative by the European Association of Urology.

Background And Objective: The purpose-built SHURUI single-port (SP) robotic platform has recently been introduced for several procedures in urology, general surgery, and gynecology. However, comparative evidence on its performance in relation to earlier models such as the da Vinci SP is lacking. Our aim was to compare the step-by-step techniques and 1-yr outcomes for radical prostatectomy (RP) between the SHURUI SP and da Vinci SP robots.

Unlabelled: In 2022, the European Commission updated its recommendation on cancer screening, inviting the Member States (MSs) to explore the feasibility of stepwise implementation of population-based screening for prostate cancer (PCa). In line with this recommendation, the PRAISE-U (Prostate Cancer Awareness and Initiative for Screening in the European Union (EU)) project was initiated. As part of the PRAISE-U, we aim to understand the current practice towards early detection in the EU MSs, the barriers to implementing or planning population-based screening programmes, and potential solutions to overcome these barriers.

Background/aim: Management of asymptomatic kidney stones is an ongoing debate with follow-up and treatment guidelines based on low-level evidence. Our aim was to evaluate current management of asymptomatic urinary stones.

Materials And Methods: A 70-question survey was designed in collaboration with European Association of Urology, Young Academic Urologists, Section of Uro-Technology and Section of Urolithiasis groups and distributed.

Background And Objective: In Europe, prostate cancer (PCa) is the most common cancer in men. Screening may therefore be crucial to lower health care costs, morbidity, and mortality. This systematic review aimed to provide a contemporary overview of the costs and benefits of PCa screening programmes.

Background: Pretreatment assessment of patients diagnosed with localized prostate cancer (PCa) is essential for therapeutic decision-making. Currently available staging systems based on prostate-specific antigen (PSA), Gleason score, and clinical stage allow for determining the prognostic characteristics of these patients. Several studies have evaluated the preoperative use of prostate-specific antigen density (PSAD) as a prognostic factor for further risk stratification.

With the new policy recommendation in 2022 to explore the possibilities of screening for prostate cancer by the European Commission, the landscape for prostate cancer early detection is evolving. In line with this recommendation, the PRAISE-U project aims to evaluate the early detection and diagnosis of prostate cancer through customised and risk-based screening programmes, with the goal to align protocols across European Union member states. This systematic review is part of the PRAISE-U project, with the goal to review the policy, medical guideline recommendations, and the current level of opportunistic screening presented in the scientific literature on prostate cancer early detection from 2016 to 2023 in European Union member states.

Background And Objective: The impact of prostate cancer of unconventional histology (UH) on oncological and functional outcomes after robot-assisted radical prostatectomy (RARP) and adjuvant radiotherapy (aRT) receipt is unclear. We compared the impact of cribriform pattern (CP), ductal adenocarcinoma (DAC), and intraductal carcinoma (IDC) in comparison to pure adenocarcinoma (AC) on short- to mid-term oncological and functional results and receipt of aRT after RARP.

Methods: We retrospectively collected data for a large international cohort of men with localized prostate cancer treated with RARP between 2016 and 2020.
