The Mayo Adhesive Probability (MAP) score is a radiographic scoring system that predicts the presence of adherent perinephric fat (APF) during partial nephrectomies (PNs). The purpose of this systematic review is to summarize the current literature on the application of the MAP score for predicting intraoperative difficulties related to APF and complications in laparoscopic PNs. Three databases, PubMed, Scopus and Cochrane, were screened, from inception to 29 October 2023, taking into consideration the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines.

Article Synopsis
  • The study aims to gather laser lithotripsy settings from experts for different clinical situations and to identify ways to minimize complications.
  • A survey was conducted among laser specialists, revealing that the majority use Holmium-YAG lasers, with variations in settings for specific scenarios like middle-ureteral, pelvic, and lower pole stones.
  • Experts reported a general consensus on preferred techniques, with preventive measures like power limits and intermittent activation commonly employed to reduce thermal injury risks during procedures.

Objectives: The objective of this study is to evaluate the prevalence and the importance of preperitoneal vas deferens (VD) infiltration in high-risk prostate cancer (PCa).

Patients And Methods: In this prospectively designed study, we included 332 high-risk PCa patients with a Briganti score >5%, who were treated by robot-assisted radical prostatectomy between July 2017 and February 2022 at the Urology Department, SLK Kliniken Heilbronn. In addition to the standard histological analysis of the distal VD, which was attached to the prostate specimen, we analysed the infiltration status of preperitoneal VD in this cohort.

On February 6, 2018, the European Atomic Energy Community reduced the annual equivalent dose limit for the lens from 150 to 20 mSv/year, because of its association with cataracts at low radiation doses. Our aim was to estimate the radiation doses received by the lens during endourologic procedures that require fluoroscopy. Multicenter study including prospective data of annual eye dosimeters between 2017 and 2020.

Background: Vapor Tunnel (VT) technology is the result of a pulse modulation during holmium laser emission which reduces stone retropulsion. We present the outcomes of this tool in the treatment of ureteral stones.

Methods: Two hundred ten patients with a ureteral stone were randomly assigned to holmium laser lithotripsy with (group A) or without (group B) the VT technology.

Introduction: Renal colic due to ureteral stones represents the primary acute condition in urology. Although guideline recommendations are available the institution, urologist, and patient preferences in diagnosis and treatment may differ. We aimed to evaluate the adherence of different European countries to the European Association of Urology (EAU) guidelines of urolithiasis and demonstrate trends in diagnostic and treatment approaches.

Purpose: We aimed to examine how different endoscopic bladder tumor resection techniques affect pathologists' clinical practice patterns.

Methods: An online survey including 28 questions clustered in four main sections was prepared by the ESUT ERBT Working Group and released to the pathologists working in the institutions of experts of the ESUT Board and the working groups and experts in the uropathology working group. A descriptive analysis was performed using the collected data.

The introduction of endoscopic anatomical enucleation of the prostate created a new educational field. We investigated the current literature for simulators, phantoms, and other training models that could be used as a tool for teaching urologists alone or within the boundaries of a course or a curriculum. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement and the European Association of Urology Guidelines office's recommendations for conducting systematic reviews.

Purpose: Transurethral resection (TURP) and photoselective vaporization of the prostate (PVP) constitute established surgical options to treat benign prostate hyperplasia. We investigated the current literature for simulators that could be used as a tool for teaching urologists alone or within the boundaries of a course or a curriculum.

Methods: A literature search was performed using PubMed, Scopus, EMBASE, and Cochrane Central Register of Controlled Trials-CENTRAL.
