Introduction: The artificial urethral sphincter (AUS) is the gold standard treatment in cases of moderate-to-severe stress urinary incontinence in males. Cuff erosions are one of the most important distant complications of AUS implantation. The optimal urethral management has still not been established.

Material and methods: Search terms related to 'urethral stricture', 'artificial urinary sphincter', and 'cuff erosion' were used in the PubMed database to identify relevant articles.

Results: In this mini review we identified 6 original articles that assessed the urethral management after AUS explantation due to cuff erosion and included urinary diversion by transurethral and/or suprapubic catheterization, urethrorrhaphy, and in situ urethroplasty. We summarized the results of different management methods and their efficacy in terms of preventing urethral stricture formation. We highlight the need for better-quality evidence on this topic.

Conclusions: The available data do not provide a clear answer to the question of optimal urethral management during AUS explantation. There is a great need to provide higher-quality evidence on this topic.

Ureteral stents are useful devices in urological surgery. The main objective of a ureteric stent is to allow passage of urine and reduce early or late complications related to obstruction in the urinary tract. Despite their widespread use, there is a general lack of knowledge and awareness in stent composition and indication of application. We represented a synthesis of our extensive research over materials, coatings and shapes available on the market and then analyzed the main characteristics and peculiarities of ureteral stents. We have also focused our attention over the side effects and complication that must be considered when placing a ureteral stent. Encrustation, microbial colonization, stent-related symptoms and patient's history must always be evaluated when there is the need for a ureteral stent. The perfect stent should have many characteristics including easy insertion and removal, easy manipulation, resistance to encrustation and migration, lack of complications, biocompatibility, radio-opacity, biodurability, affordability (cost-effectiveness), tolerability and optimal flow characteristics. Nevertheless, further research and studies need to be done to provide more information about stent composition and efficacy in vivo. In this narrative review, we covered the basic information and main characteristics of ureteral stents, in order to help clinicians choose the appropriate device needed for a given situation.

Introduction: Recurrent miscarriage is defined as 2 or more failed clinical pregnancies, typically known as repeated pregnancy loss, occurring before 20 gestational weeks, and further categorized into primary and secondary types. It represents a common and distressing condition to deal with in the field of reproductive medicine, usually affecting <5% of couples, with up to 50% of cases lacking a clearly defined aetiology. The epidemiology also varies depending on maternal age. Remarkably, the situation significantly afflicts expecting parents, whereas maternal factors, such as age and previous pregnancy loss rate, are commonly reported as risk factors. Although previously underestimated, existing evidence suggests the male factor is a possible cause of recurrent pregnancy loss.

Material and methods: A non-systematic literature review was conducted in the PubMed and Scopus databases for articles written in English investigating the possible association of the male factor in recurrent pregnancy loss. The eligible studies were synthesized in a narrative review format upon discussion and consensus among the authors after being previously independently assessed and selected.

Results: Lifestyle, obesity, genetic predisposition, chromosomal anomalies, endocrine dysfunction, anatomical abnormalities, immunological factors, infections, and oxidative stress can result in poor embryo development and recurrent miscarriage. Although professional organizations currently recognize male gender as a possible risk factor, specific recommendations on the diagnostic and therapeutic field are still lacking, and the condition necessitates a high level of suspicion and case-by-case management.

Conclusions: In this review, we delve deeper into the contribution of the male factor in the concept of recurrent miscarriage.

Introduction: This study aimed to determine whether sarcopenia is a predictor of overall survival (OS) and cancer-specific survival (CSS) in patients with bladder cancer (BC) undergoing radical cystectomy (RC).

Material and methods: Patients who underwent radical cystectomy for BC between September 2016 and June 2022 were retrospectively reviewed. Patients underwent digital computed tomography (CT) scans of the abdomen and pelvis. The skeletal muscle index (SMI) was used to assess sarcopenia using CT images. OS and CSS were estimated using Kaplan-Meier curves. Predictors of CSS and OS were analysed using univariate and multivariate Cox regression models.

Results: Of the 84 reviewed patients, 45 (53.6%) had sarcopenia. The median follow-up period for survivors was 70 months. Patients with sarcopenia were older and had a lower BMI, but other preoperative clinical and laboratory parameters were similar to those of patients without sarcopenia. During follow-up, 57 (67.9%) patients died, 39 (46.4%) due to BC. In addition, patients with sarcopenia had worse 5-year OS (24.4% vs 41.0%, p = 0.036) and CSS (35.6% vs 61.5%, p = 0.012) than non-sarcopenic patients. The findings indicate that sarcopenia is an independent predictor of increased CSS (HR, 2.841; p = 0.003) and overall mortality (HR, 2.465; p = 0.004) in multivariate analysis.

Conclusions: The results of this study support the view that sarcopenia is an important risk factor for predicting CSS and OS in BC patients undergoing RC.

Introduction: At the end of their residency program, urology trainees should reach the minimum skills required to be able to work by themselves and within a team. To achieve this objective, it is fundamental that the training involves not only surgical activities, but also theoretical, academic, and relational ones. What is the perfect balance between these activities within the ideal urological training? This study aims to evaluate the concordance in different concepts of good urological training between different perspectives (trainees vs professors).

Material and methods: Between January and December 2020 the same survey was distributed via email to 967 urology trainees and urology tutors. The survey investigated 5 educational fields: theoretical, clinical, surgical, relational, and simulation. For each field, specific questions investigated the importance of different activities and the training outcomes considered fundamental to be reached by a resident. The questions were evaluated by responders through a Likert 10-point scale.

Results: The survey was completed by 155 trainees (58.9%, Group A) and 108 tutors (41.1%, Group B) from 26 different countries. Relative to the tutors, residents assigned statistically significantly lower scores to prostate biopsy (median score 9.11 vs 9.24), robotic simulator training (5.66 vs 5.93), on-call duties with consultants (6.85 vs 7.99), as well as all aspects of relational training (e.g., proper dialogue with colleagues: 7.95 vs 8.88). Conversely, residents assigned statistically significantly higher scores, albeit below sufficiency, to the performance of robotic prostatectomy as a first operator (4.45 vs 4.26). Finally, no discrepancies between residents' and tutors' scores were recorded regarding the remaining items of clinical training (e.g., urodynamics, outpatient clinic, ward duties) and surgical training (e.g., major open, laparoscopic and endoscopic surgical training; all p values >0.05).

Conclusions: There was partial concordance between trainees and tutors regarding the activities that should be implemented and the skills that should be achieved during a urological residency. The residents aimed for more surgical involvement, while the tutors and professors, although giving importance to surgical and theoretical training, considered clinical practice as the fundamental basis on which to train future urologists.

Introduction: The pre-treatment neutrophil-to-lymphocyte ratio (NLR) has been associated with adverse pathology or survival in a variety of malignancies, including urothelial carcinoma of the bladder (UCB) treated with radical cystectomy (RC). Whether the prognostic value of NLR is retained, or even increased, when measured postoperatively remains to be studied. In this study, we evaluated the association of preoperative and postoperative NLR with oncological outcomes following RC.

Material and methods: The NLR was recorded in 132 consecutive patients with UCB treated with open RC: before surgery (NLR1), postoperatively within 2 days (NRL2), between 7 and 15 days after RC before discharge (NLR3), and a few days before recurrence or last available follow-up (NLR4).

Results: When assessed by multivariate analysis NLR1 remained independently associated with a significantly increased risk of extravesical disease (pT 3-4) (OR = 1.4, p <0.01) and lymphovascular invasion (LVI) (OR = 1.40, 95% CI 1.09-1.83, p <0.01). NLR4 was independently associated with a significantly increased risk of cancer-specific mortality (CSM) (HR = 1.14, 95%CI 1.03-1.24, p = 0.013). In a postoperative model, NLR3 was found to be an independent predictor of all-cause mortality (ACM) [HR = 1.11, 95% CI 1.02-1.21, p = 0.01]. NLR1 was associated with a significantly increased risk of recurrence in the univariable preoperative model [HR = 1.9, 95%CI 1.00-3.65, p = 0.05], while in the postoperative model NLR4 remained independently associated with a significantly increased risk of recurrence (HR = 1.13, 95%CI 1.04-1.23, p = 0.03).

Conclusions: In patients with UCB treated with RC, the NLR is associated with more advanced tumour stage, LVI, lymph node metastasis, and higher CSM. Furthermore, the variation of the NLR after surgery might play a role in predicting higher ACM and recurrence-free survival.

Introduction: Urolithiasis is a recognised disease of prevalence, and although not common, fatal sequelae can occur. There are few studies with population-based data that provide an overview of the mortality burden associated with this condition. Our aim was to perform an update based on national data from England and Wales.

Material and methods: A search was performed of the database available through the Office of National Statistics (ONS), which collates relevant information from all death certificates in England and Wales. The cause of death is classified according to the conditions listed in the International Classification of Diseases, Tenth Revision (ICD-10). The codes N 20-23 were utilised. Data were collected on gender, location in the upper or lower urinary tract, and age.

Results: Over the 23-year period, 3717 deaths caused by urolithiasis were recorded. The male-to-female ratio was 1:1.4. However, this gender gap steadily closed over time. The mean number of deaths per year was 161 (range: 98-308 year), and this gradually increased over the study period. By 2021, urolithiasis accounted for 0.1% of deaths in England and Wales. Over half of the deaths (64.9%) were in persons aged ≥75 years, while the mortality rate in persons under 50 years old was less than 4%. 0.1% of the deaths occurred in children under 15 years of age, and these were all females.

Conclusions: The number of deaths caused by urolithiasis has increased in England and Wales. Although mortality is higher among females, this gender gap is narrowing.
