Purpose To assess the impact of scanner manufacturer and scan protocol on the performance of deep learning models to classify prostate cancer (PCa) aggressiveness on biparametric MRI (bpMRI). Materials and Methods In this retrospective study, 5,478 cases from ProstateNet, a PCa bpMRI dataset with examinations from 13 centers, were used to develop five deep learning (DL) models to predict PCa aggressiveness with minimal lesion information and test how using data from different subgroups-scanner manufacturers and endorectal coil (ERC) use (Siemens, Philips, GE with and without ERC and the full dataset)-impacts model performance. Performance was assessed using the area under the receiver operating characteristic curve (AUC).

Rationale And Objectives: Accurate preoperative mpMRI-based detection of extraprostatic extension (EPE) in prostate cancer (PCa) is critical for surgical planning and patient outcomes. This study aims to evaluate the impact of endorectal coil (ERC) use on the diagnostic performance of mpMRI in detecting EPE.
Materials And Methods: This retrospective study with prospectively collected data included participants who underwent mpMRI and subsequent radical prostatectomy for PCa between 2007 and 2024.
Pre-therapeutical assessment of lower urinary tract symptoms in adult men: Systematic review and clinical practice guidelines.

Introduction: The aim was to propose initial and pre-therapeutical assessment of lower urinary tract symptoms in adult men through a systematic review and clinical practice guidelines.
Methods: These guidelines were based on a systematic review performed between January 2011 and November 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. The protocol was registered in the International Prospective Register of Systematic Reviews database (CRD42022336418).

Background: Sodium (Na) MRI of prostate cancer (PCa) is a novel but underdocumented technique conventionally acquired using an endorectal coil. These endorectal coils are associated with challenges (e.g.

We report a case of mucinous prostate cancer recurrence in the rectal wall due to biopsy needle seeding, discovered after robot-assisted radical prostatectomy.
Case Presentation: A 67-year-old man underwent robot-assisted radical prostatectomy for mucinous prostate cancer (clinical stage T2cN0M0, Gleason score of 4 + 4, and initial prostate-specific antigen level of 8.
