Urolithiasis is a prevalent condition in urology, with extracorporeal shock wave lithotripsy (ESWL) serving as a common treatment for kidney stones under 2 cm. The Mayo Adhesion Probability (MAP) score, calculated from perinephric fat characteristics, is traditionally used to assess surgical outcomes but has not been explored in the context of ESWL. This study aims to evaluate the effect of MAP score on the success rate of ESWL.

Introduction: The use of multiparametric magnetic resonance imaging (MRI) to guide prostate biopsies has improved cancer detection rates, particularly for high-grade tumors. However, despite guidelines recommending biopsies for lesions with a Prostate Imaging-Reporting and Data System (PI-RADS) score ≥ 3, the clinical significance of PI-RADS 3 lesions remains uncertain. This uncertainty, coupled with the cost and potential complications of biopsies, underscores the need for more accurate risk stratification strategies to avoid unnecessary procedures.

Article Synopsis
  • The study investigates the effectiveness of various nephrolitometric scoring systems (NSSs) in assessing success and complications for patients undergoing supine mini-percutaneous nephrolithotomy (m-PNL).
  • Out of the four NSSs analyzed (CROES, Guy's scoring system, S.T.O.N.E., and S-ReSC), only CROES, S.T.O.N.E., and S-ReSC showed significant correlations with the stone-free (SF) status after the procedure, while the Guy's scoring system did not.
  • Despite these findings, none of the NSSs were able to predict complication rates in patients, indicating their limitations in that area.

Robotic-assisted magnetic resonance imaging (MRI)/transrectal ultrasound (TRUS) fusion transperineal biopsy systems are one of the most debated and interesting subjects both in practice and in current urology literature. The comprehensive literature research was carried out in the PubMed/MEDLINE, Google Scholar, and Scopus databases using the terms "robotic transperineal prostate biopsy," "robot-assisted MRI/US fusion biopsy," "robot-assisted MRI/TRUS fusion biopsy," or "robotic targeted prostate biopsies." All article types were included in the study (n=343).

Purpose: To evaluate the performance of the European Organization for Research and Treatment of Cancer (EORTC) and the Spanish Urological Club for Oncological Treatment (CUETO) risk scoring models in non-muscle-invasive bladder cancer (NMIBC) patients defined as high risk according to European Association of Urology guidelines and managed based on current recommendations.

Material And Methods: Data from 187 high-risk NMIBC patients treated at a tertiary center between July 2010 and November 2021 were analyzed retrospectively. One- and five-year recurrence- and progression-free survival were assessed for each patient using the EORTC and CUETO risk scores.

Introduction: For the first time, the accuracy and proficiency of ChatGPT answers on urogenital tract infection (UTIs) were evaluated.

Methods: The study aimed to create two lists of questions: frequently asked questions (FAQs, public-based inquiries) on relevant topics, and questions based on guideline information (guideline-based inquiries). ChatGPT responses to FAQs and scientific questions were scored by two urologists and an infectious disease specialist.

Introduction: Prostate cancer (PCa) ranks second among prevalent cancers in men, necessitating effective screening tools such as multiparametric magnetic resonance imaging (mpMRI) with the prostate imaging reporting and data system (PI-RADS) classification. This study explores the impact of lesion volume on clinically significant prostate cancer (csPCa) detection rates in PI-RADS 3-5 lesions, aiming to contribute insights into the underexplored relationship between lesion size and csPCa detection.

Materials And Methods: A retrospective analysis was conducted on data from 754 patients undergoing mpMRI-guided transrectal ultrasound (TRUS) prostate biopsy between January 2016 and 2023.

Tranexamic acid, once a randomly used antifibrinolytic agent, has been in standard protocols for many specific surgeries. Studies are still needed to standardize the dose and route of tranexamic acid administration, examine its possible contributions in urological surgery, and establish a protocol for its use. To contribute to this goal, we designed a prospective, randomized, double-blind study on 75 patients with 1 control and 2 study groups (n = 25) who underwent percutaneous nephrolithotomy.

Background: The aim of this study was to evaluate the accuracy and reproducibility of ChatGPT's answers to frequently asked questions about benign prostate hyperplasia (BPH) and prostate cancer.

Methods: Frequently asked questions on the websites of urology associations, hospitals, and social media about prostate cancer and BPH were evaluated. Also, strong recommendation-level data were noted in the recommendations tables of the European Urology Association (EAU) 2022 Guidelines on Prostate Cancer and Management of Non-neurogenic Male Lower Urinary Tract Symptoms sections.
