Oncologic surveillance after surgical treatment for clinically localized kidney cancer: UroCCR study n. 129.

Background: In 2021, the EAU Guidelines implemented a novel, expert opinion-based follow-up scheme, with a three-risk-category system for clear cell (cc) and non-cc renal cell carcinoma (non-ccRCC) after surgery with curative intent. We aimed to validate the novel follow-up scheme and provide data-driven recurrence estimates according to risk groups, to confirm or implement the oncologic surveillance strategy.

Methods: We identified 5,320 patients from a prospectively maintained database involving 28 French referral centers.

Effect of Treatment of Residual Disease After Immunotherapy-Based Combinations on Complete Response Rate of Patients With Metastatic Renal Cell Carcinomas.

Introduction: Immune checkpoint inhibitor (ICI)-based combinations have revolutionized the management of first-line metastatic renal cell carcinoma (mRCC) by improving patient survival. Large phase 3 randomized trials assessing ICI-based combinations have reported complete response (CR) rates of 10% to 18% in the first-line setting. However, there is a scarcity of data about the effect of treatment of residual disease regarding CR rates improvement.

Asymptomatic Bacteriuria and Urological Surgery: Risk Factor or Not? Results From the National and Multicenter TOCUS Database.

Purpose: Current guidelines recommend screening and treatment of asymptomatic bacteriuria prior to all urological surgeries breaching the mucosa. But little evidence supports this recommendation. At the least, risk stratification for postoperative UTI to support this strategy is lacking.

[Short-term functional outcomes of laparoscopic robotic-assisted cystectomy (RAC) with ileal conduit urinary diversion (ICUD) for lower urinary tract dysfunction (LUTD): A single-center retrospective study].

Objective: To assess the short-term functional outcomes and morbidity of robotic-assisted cystectomy (RAC) and intracorporeal urinary diversion (ICUD) in patients with lower urinary tract dysfunction (LUTD).

A Prospective Randomized Trial of Neoadjuvant Chemohormonal Therapy vs Hormonal Therapy in Locally Advanced Prostate Cancer Treated by Radical Prostatectomy.

Purpose: Benefits of docetaxel-based neoadjuvant chemohormonal therapy (NCHT) before radical prostatectomy (RP) remain largely unknown. We explored whether docetaxel-based NCHT would bring pathological benefits and improve biochemical progression-free survival (bPFS) over neoadjuvant hormonal therapy (NHT) in locally advanced prostate cancer.

Materials And Methods: A randomized trial was designed recruiting 141 locally advanced, high-risk prostate cancer patients who were randomly assigned at the ratio of 2:1 to the NCHT group (75 mg/m body surface area every 3 weeks plus androgen deprivation therapy for 6 cycles) and the NHT group (androgen deprivation therapy for 24 weeks).

Asymptomatic bacteriuria prior to partial and radical nephrectomy: To screen or not to screen? Results from the national and multicenter TOCUS database.

Introduction: In the era of increased bacterial resistance, the main strategy is to reduce the prescription of antibiotics when possible. Nowadays, it is highly recommended to screen for asymptomatic bacteriuria (ABU), prior to urological surgery with potential mucosal breach or urine exposure. Screening and treating urinary colonization is a strategy widely adopted before radical and partial nephrectomy but without any evidence.

MR-Guided Transurethral Ultrasound Ablation (TULSA)-An Emerging Minimally Invasive Treatment Option for Localised Prostate Cancer.

The optimal treatment strategy for men with localised prostatic cancer of low and intermediate risk is an actively evolving field. It is important to strike a balance between maximal oncological control and minimal treatment-related complications, which helps preserve the patients' quality of life. MR-guided transurethral ultrasound ablation (TULSA) has emerged as a minimally invasive treatment option for this group of patients.

Primary implantation of an artificial urinary sphincter using the perineal and penoscrotal approaches: Functional results and assessment of reoperative procedures.

Introduction: Artificial urinary sphincter (AUS) is the standard treatment for severe stress urinary incontinence in men. While the perineal access is considered the gold standard, some authors have proposed penoscrotal AUS in order to facilitate the procedure. The main objective of our study was to evaluate the duration of survival without revision surgery (SSRC) according to the surgical approach for primary implantation.

Retroperitoneoscopic Clampless, Sutureless Hybrid Therapy in the Management of Renal Hilar Tumors.

Objective: We aimed to investigate the outcomes and feasibility of a retroperitoneoscopic clampless, sutureless hybrid technique in the management of renal hilar tumors.

Methods: A retrospective cohort of consecutive patients with renal hilar tumors who received retroperitoneoscopic clampless, sutureless hybrid therapy between January 2017 and April 2021 was included. The hybrid surgical technique involved microwave ablation (MWA), followed by clampless tumor enucleation and sutureless hemostasis.

Which revision strategy is the best for non-mechanical failure of male artificial urinary sphincter?

Purpose: Persistence or recurrence of stress urinary incontinence (prSUI) after artificial urinary sphincter (AUS) implantation may be secondary to non-mechanical failure (NOMECA). It have for long been assumed to result from urethral atrophy. Its existence is now debated.

Nephrometry scores to predict oncological outcomes following partial nephrectomy (UroCCR Study 70).

Purpose: Partial nephrectomy (PN) for large or complex renal tumors can be difficult and associated with a higher risk of recurrence than radical nephrectomy. We aim to evaluate the clinical useful of nephrometry scores for predicting oncological outcomes in a large cohort of patients who underwent PN for renal cell carcinomas.

Methods: Our analysis included patients who underwent PN for renal cell carcinoma in 21 French academic centers (2010-2020).

Outcomes of holmium laser enucleation of the prostate (HoLEP) for very large-sized benign prostatic hyperplasia (over 150 mL): open simple prostatectomy is dead.

Introduction: Our study aimed to describe the outcomes of transurethral enucleation of the prostate (HoLEP) for large-sized benign prostatic hyperplasia over 150 mL (bBPH).

Methods: We conducted a retrospective, descriptive, and analytical study of patients undergoing HoLEP for bBPH. The primary endpoint was the success of the procedure, defined by a mixed criteria: complete endoscopic enucleation of the prostate, absence of blood transfusion or reoperation for bleeding, post-operative improvement of quality of life (assessed by a ≥ 2 points increase at in the 8th question of the IPSS test) and post-operative continence (no pads use) at 3 months.

Mesenchymal-like Tumor Cells and Myofibroblastic Cancer-Associated Fibroblasts Are Associated with Progression and Immunotherapy Response of Clear Cell Renal Cell Carcinoma.

Unlabelled: Immune checkpoint inhibitors (ICI) represent the cornerstone for the treatment of patients with metastatic clear cell renal cell carcinoma (ccRCC). Despite a favorable response for a subset of patients, others experience primary progressive disease, highlighting the need to precisely understand the plasticity of cancer cells and their cross-talk with the microenvironment to better predict therapeutic response and personalize treatment. Single-cell RNA sequencing of ccRCC at different disease stages and normal adjacent tissue (NAT) from patients identified 46 cell populations, including 5 tumor subpopulations, characterized by distinct transcriptional signatures representing an epithelial-to-mesenchymal transition gradient and a novel inflamed state.
