The global rise of end-stage renal disease is leading to an increase in kidney transplants. Graft survival is dependent on the occurrence of inflammation which can lead to cases of rejection. Traditional laboratory analyses often lack accuracy, and graft biopsies - the current gold standard - are considered invasive and risky.
View Article and Find Full Text PDFBackground And Objective: A renal mass biopsy (RMB) is not systematically recommended before surgical excision of a renal mass, although it has demonstrated elevated accuracy in determining renal masses with low morbidity. Our aim was to determine the diagnostic accuracy of an RMB, the clinical and tumoral factors associated with RMB practice, and the impact of an RMB on renal cell carcinoma management in a contemporary prospective national registry-UroCCR (2010-2021).
Methods: We identified all patients with a single renal mass (pT1-4 N0-2 M0 or benign) who were treated surgically and stratified them according to the performance of a prior RMB.
Introduction: The boom in surgery for benign prostatic hyperplasia using Holmium laser enucleation (HoLEP) has reduced length of hospitalization, catheterization duration and the risk of bleeding, with comparable results to the old gold standard. The aim of this study is to evaluate the evolution of medium-term functional results after HoLEP.
Method: Retrospective monocentric observational study in patients who underwent HoLEP surgery from 2014 to 2019.
Introduction: Cystoscopy is the most commonly performed urological examination during consultation. Various guidelines outline the benefits of performing urine culture before cystoscopy. The main objective of this study was to evaluate the impact of untreated positive urine cultures before cystoscopy on post-interventional urinary tract infection (UTI) rate.

Purpose: The objective of this scoping review was to identify the topics of research and the types of studies published by the French Association of Urologists in Training (AFUF) since it was created, 35 years ago and to perform a bibliometric analysis.
Methods: A scoping review on PubMed, Google scholar, Excerpta Medica database (EMBASE) was conducted from 1989 until the 31st of December 2023. The PRISMA extended guidelines for scoping reviews were followed.
Introduction: Sexuality is an integral part of well-being. Urologists are a population faced with a significant workload and stress that can affect their sexuality. The purpose of this study was to investigate sexuality in this population and assess factors that may impact it.
View Article and Find Full Text PDFPurpose: To evaluate biopsy-related complications and detection rates of any PCa and clinically significant PCa (csPCa, intended as grade group ≥ 2) between MRI-targeted TP fusion biopsies (TPBx) and TR ones (TRBx).
Methods: We performed a multicentric study on 4841 patients who underwent fusion biopsy between 2016 and 2023. A case-control matching was performed to find comparable cohorts of 646 TPBx and 646 TRBx.
Introduction: MRI-targeted biopsy improves detection of significant prostate cancer (csPCa) and grade prediction. The aim of this study was to identify factors improving the diagnostic performance of targeted biopsies (TB) in detecting csPCa.
Methods: Retrospective monocenter study of patients who underwent a radical prostatectomy (RP) for prostate cancer (PCa) and diagnosed by transrectal combined biopsies (CB) with elastic MRI/ultrasound fusion.
Background And Objective: A hilar location for a renal tumour is sometimes viewed as a limiting factor for safe partial nephrectomy. Our aim was to evaluate perioperative, oncological, and functional outcomes of robot-assisted partial nephrectomy (RAPN) for hilar tumours (RAPN-H) in comparison to RAPN for nonhilar tumours (RAPN-NH).
Methods: We conducted an observational, multicentre cohort study using prospectively collected data from the French Research Network on Kidney Cancer (UroCCR).
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).
View Article and Find Full Text PDFPurpose: Utility of prostate-specific antigen density (PSAd) for risk-stratification to avoid unnecessary biopsy remains unclear due to the lack of standardization of prostate volume estimation. We evaluated the impact of ellipsoidal formula using multiparametric magnetic resonance (MRI) and semi-automated segmentation using tridimensional ultrasound (3D-US) on prostate volume and PSAd estimations as well as the distribution of patients in a risk-adapted table of clinically significant prostate cancer (csPCa).
Methods: In a prospectively maintained database of 4841 patients who underwent MRI-targeted and systematic biopsies, 971 met inclusions criteria.
Background And Objective: Data regarding open conversion (OC) during minimally invasive surgery (MIS) for renal tumors are reported from big databases, without precise description of the reason and management of OC. The objective of this study was to describe the rate, reasons, and perioperative outcomes of OC in a cohort of patients who underwent MIS for renal tumor initially. The secondary objective was to find the factors associated with OC.
View Article and Find Full Text PDFBackground 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.

Young urologists and residents are involved in this activity mostly performed in emergency. How do they feel about KT training? Is KT an attractive part of the urologist activity?
Methods: This survey has been designed in the form of a questionnaire by the French Committee of Kidney Transplantation (CTAFU) and the French Association of Urologists in training (AFUF).
Objective: To assess the current knowledge of French urology residents and fellows about neurogenic lower urinary tract dysfunction and their management in patients with spina bifida.
Material And Method: A 7-question questionnaire, covering the responder's experience and the various stages in the neuro-urological management of spina bifida, was drafted by an expert urologist. Responses were collected within 5days of being e-mailed to members of the Association française des urologues en formation (AFUF), and a descriptive analysis was carried out.
Introduction: In the era of targeted prostate biopsies, the necessity of performing randomized biopsies systematically is under question. Our objective is to evaluate the rate of clinically significant prostate cancer (csPCa), defined by presence of ISUP≥2 prostate cancer, diagnosed only on randomized cores in case of a PIRADS≥4 target lesion on MRI. The secondary objective is to evaluate whether specific variables can predict the presence of undetected csPCa in targeted biopsies.
View Article and Find Full Text PDFBackground: Systematic biopsy (SB) combined with magnetic resonance imaging (MRI)-targeted biopsy is still recommended considering the risk of missing clinically significant prostate cancer (csPCa).
Objective: To evaluate the added value in csPCa detection on side-specific SB relative to MRI lesion and to externally validate the Noujeim risk stratification model that predicts the risk of csPCa on distant SB cores relative to the index MRI lesion.
Design, Setting, And Participants: Overall, 4841 consecutive patients diagnosed by MRI-targeted biopsy and SB for Prostate Imaging Reporting and Data System score ≥3 lesions were identified from a prospectively maintained database between January 2016 and April 2023 at 15 European referral centers.
Objective: To determine (i) whether urologist seniority and experience are associated with prostate cancer (CaP) and clinically significant CaP (csCaP) detection rates using magnetic resonance imaging/ultrasound (MRI/US) fusion-guided targeted biopsies, taking multiparametric magnetic resonance imaging (mpMRI) as the reference standard, and (ii) if cancer detection rates (CDR) differ across regions of the prostate using Dickinson's 27-sector map, regardless of seniority.
Methods: We retrospectively reviewed a consecutive series of patients with suspicion of prostate cancer who underwent targeted and systematic biopsies at 1 center by 1 of 7 urologists (2 seniors and 5 juniors) between January 1, 2016 and December 31, 2021, following positive mpMRI.
Results: The cohort comprised 403 patients (454 lesions) aged 67.

Urine is a very interesting and attractive biofluid for biomarker discovery and medical diagnosis research due to its non-invasiveness collection and richness of potential biomarkers. Fourier-Transform Infrared (FTIR) spectroscopy applied on urine samples is a promising tool that could be used as a screening method for various diseases. However, during method development, frozen urine is more accessible, especially for inter-laboratory studies, whereas in routine application fresh urine is more convenient.
