Background And Objective: Artificial urinary sphincter (AUS) is commonly used in France in female patients with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD). However, it has never been assessed using patient-reported outcomes. This study aimed to evaluate the functional outcomes of robotic AUS implantation using validated questionnaires.

Purpose: While pump manipulation is rarely problematic in male patients with artificial urinary sphincters (AUSs), the situation may differ in female patients due to anatomical or cultural factors. This study aimed to evaluate the prevalence of difficulties in pump manipulation among female AUS patients, identify associated risk factors, and explore management strategies for this challenging issue.

Methods: Data were collected from all female patients who underwent a robotic AUS implantation at a single academic center between 2014 and 2022.

Article Synopsis
  • - The article focuses on Posterior Urethral Stenosis (PUS), discussing the surgical challenges and summarizing current management practices based on a review of literature and recommendations from key urological associations.
  • - The review highlights different types of PUS, such as those resulting from pelvic fractures, benign prostatic hyperplasia (BPH), prostatectomy, and radiotherapy, each presenting unique treatment challenges and risks.
  • - Treatment strategies for PUS are varied and should be tailored to the specific location and cause of the stenosis, balancing surgical options with the patient’s overall health and the potential impacts on urinary and sexual functions.

Introduction: Distal anterior urethral strictures (DAUS) affect the meatus, navicular fossa (NF) and penile urethra (PU). The main causes are inflammatory (lichen sclerosous [LS]), traumatic iatrogenic, or idiopathic. Post-hypospadias stenosis is common and constitutes a separate entity, dealt with in a separate article.

Background: A significant proportion of trans women is demanding for a genital gender-affirming surgery, with vulvo-vaginoplasty being the most frequently requested procedure. The gold standard for primary vaginoplasty in trans women is the penile skin inversion technique with scrotal skin graft, which allows for increased depth of the vaginal cavity.

Aims: The assessment of vulvo-vaginoplasty outcomes utilizing penile skin inversion and scrotal skin graft in individuals assigned male at birth in the surgeon's learning curve involves evaluating aesthetics, functionality, and sexual aspects.

Introduction: Peyronie's and Dupuytren's diseases are benign but are source of significant functional impairment leading to considerable suffering. In this study, the aim is to investigate the association between Peyronie's and Dupuytren's diseases as well as their common and specific risk factors.

Material And Methods: From July 2022 to March 2024, we conducted a multicentric observational study on 450 patients.

Purpose: Previous studies suggested better functional outcomes and longer device survival for female artificial urinary sphincter (AUS) implantation compared to male AUS implantation. We hypothesized that the adoption of robotic approaches for female implantation might have influenced these comparisons. This study aimed to compare the outcomes of robotic female AUS and male AUS implantation for non-neurogenic stress urinary incontinence (SUI).

Introduction: The Operated Male-to-Female Sexual Function Index (oMtFSFI) questionnaire is the first scoring system developed to assess sexual function after gender-affirming vulvo-vaginoplasty, and was initially developed and validated in Italian. The aim of this study was to provide linguistic validation of the questionnaire in French through several steps including use of the questionnaires across a series of patients who had undergone gender-affirming vulvo-vaginoplasty between 2020 and 2022 at two French academic centers.

Method: The French version of the oMtFSFI questionnaire was obtained through a double translation (Italian to French) and a back-translation (French to Italian), validated by a scientific committee, and cognitively assessed by a panel of expert patients.

Purpose: To compare the outcomes of patients undergoing robotic YV plasty for bladder neck contracture (BNC) vs. vesico-urethral anastomotic stricture (VUAS).

Methods: A retrospective study included male patients who underwent robotic YV plasty for BNC after endoscopic treatment of BPH or VUAS between August 2019 and March 2023 at a single academic center.

Purpose: Cut-off time to avoid orchiectomy relies on small series of patients. The objective was to determine the cut-off time to avoid orchiectomy in torsion of the spermatic cord in a large cohort.

Methods: We performed a retrospective multicenter study (TORSAFUF cohort) of patients with suspected spermatic cord torsion between 2005 and 2019.

Introduction: Most of the time, female-to-male (FtoM) chest surgery involves mastectomy techniques and free transplantation of the nipple-areola complex. With the increasing prevalence of gender dysphoria and the demand for female-to-male gender reassignment surgery, the need for FtM top surgery is also rising. To meet this demand, we present a new approach: the PIPe technique, based on a fasciocutaneous flap with a posteroinferior pedicle.

Genetic factors are responsible for 15% of male infertility conditions. Numerical and structural chromosomal anomalies are validated genetic factors leading to spermatogenic quantitative defects, with a frequency depending on the severity of the phenotype. Among the structural chromosomal rearrangements, dicentric chromosomes are generally observed in robertsonian translocations or in cases of Y chromosome isodicentrics.

Article Synopsis
  • - The study aimed to analyze the 30-day mortality rate after renal trauma and determine factors that contribute to mortality, using data from 1,799 patients across 17 hospitals in France from 2005 to 2015.
  • - The findings revealed a 30-day mortality rate of 3.27%, with only a small percentage of deaths directly attributable to renal trauma; significant risk factors included age over 40, hemodynamic instability, anemia, bilateral renal trauma, arterial contrast extravasation, and concurrent visceral and bone injuries.
  • - The study highlights that mortality rates after renal trauma are primarily linked to multiple associated injuries rather than solely from the trauma itself, providing insights that could assist healthcare professionals in identifying patients at higher risk

Acute scrotal pain (ASP) requiring surgical exploration is common in the pediatric population, but little has been reported on this subject with regard to the adult population. The aim of this study was to investigate the demographic and clinical characteristics and outcomes of scrotal explorations performed on adult patients. Patients over 21 years of age who underwent surgical exploration for ASP with suspected testicular torsion (TT) at 14 French hospitals between January 2005 and December 2019 were included in this study.
