[Endoscopic management of upper urinary tract stones].

The treatment of upper urinary tract stones is one of the main urological activities. Endoscopic surgical techniques, namely semirigid or flexible ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL), represent a major therapeutic modality, alternatively to chemolysis, extracorporeal shock wave lithotripsy and open, laparoscopic or robotic-assisted surgery. In this article, the specificities of these endoscopic techniques, their clinical performances, as well as their development following recent technological advances are discussed.

External validation and comparison of magnetic resonance imaging-based risk prediction models for prostate biopsy stratification.

Purpose: Magnetic resonance imaging (MRI) is a promising tool for risk assessment, potentially reducing the burden of unnecessary prostate biopsies. Risk prediction models that incorporate MRI data have gained attention, but their external validation and comparison are essential for guiding clinical practice. The aim is to externally validate and compare risk prediction models for the diagnosis of clinically significant prostate cancer (csPCa).

Transperineal or Transrectal Magnetic Resonance Imaging-targeted Biopsy for Prostate Cancer Detection.

Background And Objective: A notable paradigm shift has emerged in the choice of prostate biopsy approach, with a transition from transrectal biopsy (TRBx) to transperineal biopsy (TPBx) driven by the lower risk of severe urinary tract infections. The impact of this change on detection of clinically significant prostate cancer (csPCa) remains a subject of debate. Our aim was to compare the csPCa detection rate of TRBx and TPBx.
