Introduction: The aim of this article was to evaluate the accuracy of European Randomized study of Screening for Prostate Cancer (ERSPC 4) and Prostate Cancer Prevention Trial (PCPT 2.0) risk calculator on predicting high-grade prostate cancer (HGPCa) and accuracy of Partin and Briganti nomograms on organ confined (OC) or extraprostatic cancer (EXP), seminal vesicles invasion (SVI) and risk of lymph nodes metastasis.

Material and methods: A cohort of 269 men aged between 44-84 years, who underwent radical prostatectomy was retrospectively analysed. Based on estimated calculator risk, patients were divided into risk groups: low (LR), medium (MR) and high (HR). Results obtained with calculators were compared to post-surgical final pathology outcome.

Results: In ERPSC4, the average risk for HGPC was LR = 5%, MR = 21%, and HR = 64%. In PCPT 2.0, the average risk for HG was: LR - 8%, MR - 14%, and HR - 30%. In the final results, HGPC was observed in: LR = 29%, MR = 67%, and HR = 81%. In Partin, LNI was estimated to occur in: LR = 1%, MR = 2%, and HR = 7.5% and in Briganti: LR = 1.8%, MR = 11.4%, and HR = 44.2% while finally it was found in: LR = 1.3%, MR = 0%, and HR = 11.6%.

Conclusions: ERPSC 4 and PCPT 2.0 corresponded well with each other as well as Partin and Briganti. ERPSC 4 was more accurate in predicting HGPC than PCPT 2.0. Partin was more accurate as for LNI than Briganti. In this study group a large underestimation was observed in reference to Gleason grade.

Introduction: The Acute Cystitis Symptom Score (ACSS) is a self-reporting questionnaire to evaluate the symptoms and quality of life in women with uncomplicated acute cystitis (AC). The aim of the current study was the additional cognitive and clinical validation of the Polish version.

Material and methods: Professional forward and backward translations from original Russian to Polish were performed by Mapi SAS. For cognitive assessment, women with different ages and educational levels were asked to comment on each item of the Polish ACSS to establish the final study version. The clinical validation was performed as a prospective, non-interventional cohort study. Women with AC (Patients) and those without (Controls) filled in the Polish ACSS during their visits to a physician's office and at a follow-up visit. Statistical analysis included ordinary descriptive values, calculation of reliability, validity, discriminative ability, responsiveness (sensitivity, specificity), and comparative analysis.

Results: The cognitive assessment was performed in 60 women with a median (range) age of 44.5 (21-88) years and different educational levels: grade school (n = 8), high school (n = 25), college (n = 22), and postgraduate education (n = 5). Forty-three patients were recruited for the clinical validation study along with 34 controls. Statistical analyses resulted in excellent values of internal consistency, discriminative ability, and validity for diagnosis of AC. At a summary score of 6 and higher in the ´Typical´ domain, positive and negative predictive values were 97% and 79%, and sensitivity and specificity were 79% and 97%, respectively.

Conclusions: The Polish version of the ACSS has demonstrated benefits for diagnosis and patient-reported outcome assessment. It is objective, fast, and cost-effective, and it may help to easily confirm the accurate diagnosis of AC. The Polish ASCSS can now be recommended for use in clinical and epidemiological studies, in clinical practice, or for self-diagnosis and patient-reported outcome in women with symptoms of AC.

Introduction: The aim of this study was to assess the association between the type and number of D'Amico high-risk criteria (DHRCs) with rates of pathologically non-organ-confined (NOC) prostate cancer in patients treated with radical prostatectomy (RP) and pelvic lymphadenectomy (PLND).

Material and methods: In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 12961 RP and PLDN patients with at least one DHRC. We relied on descriptive statistics and multivariable logistic regression models.

Results: Of 12 961 patients, 6135 (47%) exclusively harboured biopsy Gleason score (GS) 8-10, 3526 (27%) had clinical stage ≥T2c, and 1234 (9.5%) had prostate-specific antigen (PSA) >20 ng/mL. Only 1886 (15%) harboured any combination of 2 DHRCs. Finally, all 3 DHRCs were present in 180 (1.4%) patients. NOC rates increased from 32% for clinical T stage ≥T2c to 49% for either GS 8-10 only or PSA >20 ng/mL only and to 66-68% for any combination of 2 DHRCs, and to 84% for respectively all 3 DHRCs, which resulted in a multivariable logistic regression OR of 1.00, 2.01 (95% CI 1.85-2.19; p <0.001), 4.16 (95% CI 3.69-4.68; p <0.001), and 10.83 (95% CI 7.35-16.52; p <0.001), respectively.

Conclusions: Our study indicates a stimulus-response effect according to the type and number of DHRCs. Hence, a formal risk-stratification within high-risk prostate cancer patients should be considered in clinical decision-making.

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.
