Risk of bleeding after retrograde intrarenal surgery vs miniaturised percutaneous nephrolithotomy for 10-20 mm renal stones: a not so different safety profile.

Objective: To assess differences in bleeding risk between retrograde intrarenal surgery (RIRS) and minimally invasive miniaturised percutaneous nephrolithotomy (mini-PCNL) for 10-20 mm renal stones.

Patients And Methods: A total of 176 patients with a renal stone between 10 and 20 mm were treated. For all patients the Stone Management According to Size-Hardness (SMASH) score was calculated: Hounsfield units × stone maximum size (cm)/100.

Chiral Symmetry Breaking in Colloidal Metal Nanoparticle Solutions by Circularly Polarized Light.

Shape symmetry breaking in the formation of inorganic nanostructures is of significant current interest. It was typically achieved through the growth of colloidal nanoparticles with adsorbed chiral molecules. Photochemical processes induced through asymmetric plasmon excitation by circularly polarized light in surface immobilized nanostructures also led to symmetry breaking.

Surveillance after Focal Therapy - a Comprehensive Review.

Background: to date, no standardized, evidence-based follow-up schemes exist for the monitoring of patients who underwent focal therapy (FT) and expert centers rely mainly on their own experience and/or institutional protocols. We aimed to perform a comprehensive review of the most advantageous follow-up strategies and their rationale after FT for prostate cancer (PCa).

Methods: a narrative review of the literature was conducted to investigate different follow-up protocols of FT for PCa.

Cryotherapy versus radical prostatectomy as a salvage treatment for radio-recurrent prostate cancer.

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.

Electromagnetic Enantiomer: Chiral Nanophotonic Cavities for Inducing Chemical Asymmetry.

Chiral molecules, a cornerstone of chemical sciences with applications ranging from pharmaceuticals to molecular electronics, come in mirror-image pairs called enantiomers. However, their synthesis often requires complex control of their molecular geometry. We propose a strategy called "electromagnetic enantiomers" for inducing chirality in molecules located within engineered nanocavities using light, eliminating the need for intricate molecular design.
