The detection rate for prostate cancer in systematic and targeted prostate biopsy in biopsy-naive patients, according to the localization of the lesion at the mpMRI: A single-center retrospective observational study.

OBJECTIVE: Evaluate the detection rates of systematic, targeted and combined cores at biopsy according to tumor positions in biopsy-naïve patients. MATERIAL AND METHODS: A retrospective analysis of a single-center patient cohort (n = 501) that underwent transrectal prostate biopsy between January 2017 and December 2019 was performed. Multi-parametric MRI was executed as a prebiopsy investigation. Biopsy protocol included, for each patient, 12 systematic cores plus 3 to 5 targeted cores per lesion identified at the mpMRI. Pearson and McNemar chi-squared tests were used for statistical analysis to compare tumor location-related detection rates of systematic, targeted and combined (systematic + targeted) cores at biopsy. RESULTS: Median age of patients was 70 years (IQR 62-72), with a median PSA of 8.5 ng/ml (IQR 5.7-15.6). Positive biopsies were obtained in 67.7% of cases. Overall, targeted cores obtained higher detection rates compared to systematic cores (54.3% vs. 43.1%, p < 0.0001). Differences in detection rates were, however, higher for tumors located at the apex (61.1% vs. 26.3%, p < 0.05) and anteriorly (44.4% vs. 19.3%, p < 0.05). Targeted cores similarly obtained higher detection rates in the posterior zone of the prostate gland for clinically significant prostate cancer. A poor agreement was reported between targeted and systematic cores for the apex and anterior zone of the prostate with, respectively κ = 0.028 and κ = -0.018. CONCLUSION: A combined approach of targeted and systematic biopsy delivers the highest detection rate in prostate cancer (PCa). The location of the tumor could however greatly influence overall detection rates, indicating the possibility to omit (as for the base or posterior zone of the gland) or add (as for the apex or anterior zone of the gland) further targeted cores.

Unlocking Precision Medicine: Liquid Biopsy Advancements in Renal Cancer Detection and Monitoring.

Renal cell carcinoma (RCC) remains a formidable diagnostic challenge, especially in the context of small renal masses. The quest for non-invasive screening tools and biomarkers has steered research towards liquid biopsy, focusing on microRNAs (miRNAs), exosomes, and circulating tumor cells (CTCs). MiRNAs, small non-coding RNAs, exhibit notable dysregulation in RCC, offering promising avenues for diagnosis and prognosis. Studies underscore their potential across various biofluids, including plasma, serum, and urine, for RCC detection and subtype characterization. Encouraging miRNA signatures show correlations with overall survival, indicative of their future relevance in RCC management. Exosomes, with their diverse molecular cargo, including miRNAs, emerge as enticing biomarkers, while CTCs, emanating from primary tumors into the bloodstream, provide valuable insights into cancer progression. Despite these advancements, clinical translation necessitates further validation and standardization, encompassing larger-scale studies and robust evidence generation. Currently lacking approved diagnostic assays for renal cancer, the potential future applications of liquid biopsy in follow-up care, treatment selection, and outcome prediction in RCC patients are profound. This review aims to discuss and highlight recent advancements in liquid biopsy for RCC, exploring their strengths and weaknesses in the comprehensive management of this disease.

Long-term functional outcomes and surgical retreatment after thulium laser enucleation of the prostate: A 10-year follow-up study.

BACKGROUND: To evaluate the 10-year functional outcomes (primary) and frequency and predictors of BPH surgical retreatment (secondary) after ThuLEP. MATERIALS AND METHODS: A single-center retrospective analysis of consecutive patients undergoing ThuLEP between 2010 and 2013 was performed. Inclusion criteria were: age ≥ 40 years, prostate volume (PV) ≥ 80 mL, International Prostate Symptom Score (IPSS)-Total score ≥ 8 points. IPSS-Total score was the primary outcome, and BPH surgical retreatment rate was the secondary outcome. Paired t-test, McNemar test, and Wilcoxon signed-rank test were used to compare variables. Logistic regression analysis was performed to evaluate predictors of surgical retreatment. RESULTS: A total of 410 patients with a mean ±SD age of 63.9 ± 9.7 years and a PV of 115.6 ± 28.6 mL were included. Mean ±SD follow-up was 108.2 ± 29.6 months. IPSS-Total score was significantly improved at 1 year compared to baseline (23.3 ± 4.7 vs. 10.3 ± 3.8; p<0.001). It was similar after 5 years (10.5 ± 3.6 vs. 10.7 ± 5.0; p=0.161), with a significant worsening at 10 years (10.3 ±4.8 vs. 13.8 ±4.5; p=0.042) but remaining statistically and clinically better than baseline (13.8 ±4.5 vs. 22.1 ±4.3; p<0.001). After 10 years, 21 (5.9%) patients had undergone BPH reoperation. Baseline PV (adjusted OR 1.27, 95% CI 1.09-1.41; p<0.001) and time from BPH surgery (adjusted OR 1.32, 95% CI 1.15-1.43; p<0.001) were predictors of BPH surgical retreatment. CONCLUSIONS: ThuLEP is associated with optimal functional outcomes and a low frequency of BPH surgical retreatment in the long-term. Baseline PV and time from surgery were predictors of BPH reoperation.

YouTubeTM as a source of information on bladder pain syndrome: A contemporary analysis.

AIM: To evaluate the quality of YouTube™ videos on bladder pain syndrome (BPS) and to investigate whether they can be used as a reliable source of information. METHODS: The search term "bladder pain syndrome" was used on YouTubeTM platform. The first 100 videos were selected. Patient Education Materials Assessment Tool for audio-visual content (PEMAT A/V), Global Quality Score (GQS), Misinformation tool, and DISCERN score were used to assess videos' quality content. Pearson's test was used to assess potential correlations between variables. RESULTS: Seventy-nine videos were suitable for the analyses. The median PEMAT A/V Understandability score and PEMAT A/V Actionability score were 66.7% (interquartile range [IQR]: 46.2-100.0) and 75.0% (IQR: 37.5-100.0), respectively. According to GQS, 26 (32.9%), 32 (40.5%), 3 (3.8%), 15 (19.0%), and 3 (3.8%) videos were excellent, good, moderate, generally poor, and poor, respectively. According to Misinformation tool, of all videos, 81% (n = 64), 6.3% (n = 5), 5.1% (n = 4), 5.1% (n = 4), 2.5% (n = 2) had respectively no, very little, moderate, high, and extreme misinformation. The overall median DISCERN score ranged from 5.0 (IQR: 2.0-5.0) to 5.0 (IQR: 5.0-5.0). A positive statistically significant correlation was found between video length and PEMAT A/V Understandability (r = 0.27, p = 0.01), video length and PEMAT A/V Actionability (r = .26, p = 0.02), and video length and DISCERN Question 16 (r = 0.28, p = 0.01). CONCLUSIONS: Nowaday, the overall quality of YouTubeTM videos on BPS have been evaluated good according to PEMAT A/V, GQS, Misinformation tool, and DISCERN score. It is possible to assume that YouTubeTM may be considered as a reliable source of information on BPS.

Translabial ultrasound: a non-invasive technique for assessing "technical errors" after TOT failure.

INTRODUCTION AND HYPOTHESIS: The aims of this study were to evaluate by transperineal ultrasound if there were ultrasound-detectable changes over time in the dynamic behavior of the sling in patients who underwent transobturator tape (TOT), and to evaluate if dynamic translabial ultrasonography recognized factors that may be associated with failed surgery. METHODS: This was a single-center prospective study. We included women who underwent "out-in" TOT for stress urinary incontinence (SUI). A dynamic translabial ultrasound was performed 6 months post-surgery and again at the last visit. The objective cure for SUI was defined as the absence of urine leakage during the stress test. We evaluated the bladder neck mobility at rest and during Valsalva; the position of the mesh along the urethra; the concordance of urethral movement with the sling during Valsalva; the symmetry of the lateral arms of the sling during straining; and the presence or absence of bladder neck funneling. RESULTS: From December 2012 to February 2016, 80 consecutive patients were included. Six months after surgery, incontinent women compared with continent women had the sling in a proximal or distal position, that moved discordantly with the urethra (p < 0.0001), with asymmetry arm and bladder neck funneling (p < 0.0001). Continent patients had a significant improvement of urethrocele grade both at rest (p = 0.036) and during Valsalva (p = 0.045). CONCLUSIONS: Technical and positioning errors can lead to the failure of anti-incontinence surgical treatment. Translabial ultrasound allows the correct positioning of the sling to be evaluated and any errors that need to be analyzed in order to then solve the failure.

Micro-Ultrasound in the Diagnosis and Staging of Prostate and Bladder Cancer: A Comprehensive Review.

Background and Objectives: Multiparametric magnetic resonance imaging (mpMRI) of the prostate and prostate-specific membrane antigen positron emission tomography (PSMA PET) are some examples of how the advancement of imaging techniques have revolutionized the diagnosis, staging, and consequently management of patients with prostate cancer (PCa). Although with less striking results, novel radiological modalities have also been proposed for bladder cancer (BCa) in recent years. Micro-ultrasound (MUS) is an imaging examination characterized by high real-time spatial resolution, recently introduced in the urological field. This article aimed to describe the current evidence regarding the application of MUS for the diagnosis and staging of PCa and BCa. Materials and Methods: We designed a narrative review. A comprehensive search in the MEDLINE, Scopus, and Cochrane Library databases was performed. Articles in English-language and published until July 2022 were deemed eligible. Retrospective and prospective primary clinical studies, as well as meta-analyses, were included. Results: MUS-guided prostate biopsy showed high sensitivity (0.91, 95% CI, 0.79-0.97) in the diagnosis of clinically significant PCa (csPCa). It was associated with a higher detection rate of csPCa than a systematic biopsy (1.18, 95% CI 0.83-1.68). No significant difference was found between MUS and mpMRI-guided biopsy in the total detection of PCa (p = 0.89) and in the detection of Grade Groups ≥ 2 (p = 0.92). The use of MUS to distinguish between non-muscle-invasive and muscle-invasive BCa was described, highlighting an up-staging with MUS only in a minority of cases (28.6%). Conclusions: Promising findings have emerged regarding the feasibility and accuracy of MUS in the diagnosis and staging of PCa and BCa. However, the available evidence is limited and should be considered preliminary.

Prolapse Surgery: What Kind of Antibiotic Prophylaxis Is Necessary?

INTRODUCTION: The aim of this study was to assess whether antibiotic prophylaxis or therapy is sufficient for laparoscopic or vaginal prolapse surgery with mesh. METHODS: This is a single-center prospective study. The study was divided into 3 groups. Protocol A: metronidazole (15 mg/kg) and piperacillin-tazobactam (2 g) 1 h before surgery and, for postoperative treatment, gentamycin (160 mg) 1 h before surgery in a single dose. Metronidazole and piperacillin-tazobactam were administered until hospital discharge. Protocol B: gentamycin and piperacillin-tazobactam in the same manner as group A. Protocol C: clindamycin (600 mg) and gentamicin (160 mg) 1 h before surgery in a single dose. RESULTS: We included 87 consecutive patients who underwent prolapse surgery involving mesh prostheses: 57 by the laparoscopic approach and 30 by the vaginal route. Of these, 30 patients were included in protocol A, 30 in protocol B, and 27 in protocol C. There were no statistically significant differences among the 3 protocols regarding any postoperative complications, except for urinary tract infections that were more in the vaginal approach than in the laparoscopic route, in protocol A (p = 0.002). CONCLUSIONS: One-shot prophylaxis can be successfully used in prolapse surgery regardless of the surgical approach.

Could COVID-19 have an impact on male fertility?

The pandemic caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to several hypotheses of functional alteration of different organs. The direct influence of this virus on the male urogenital organs is still to be evaluated. However some hypotheses can already be made, especially in the andrological field, for the biological similarity of the SARS-CoV and SARS-CoV2. As well as SARS-CoV, SARS CoV-2 uses the 'Angiotensin Converting Enzyme-2' (ACE2) as a receptor to enter human cells. It was found that ACE2, Angiotensin (1-7) and its MAS receptors are present, over in the lung, also in the testicles, in particular in Leydig and Sertoli cells. A first hypothesis is that the virus could enter the testicle and lead to alterations in testicular functionality. A second hypothesis is that the binding of the virus to the ACE2 receptor, could cause an excess of ACE2 and give rise to a typical inflammatory response. The inflammatory cells could interfere with the function of Leydig and Sertoli cells. Both hypotheses should be evaluated and confirmed, in order to possibly monitor fertility in patients COVID-19+.

Voice Assistants as Consultants for Male Patients with Sexual Dysfunction: A Reliable Option?

The aim of this study was to evaluate the ability of Google Assistant, Alexa, and Siri to recognize and answer questions about male sexual health. Each VA was tested on a smart speaker: Alexa on Amazon Echo Dot 4th Gen., Google Assistant on Google Home Mini, and Siri on Apple HomePod. A pool of patients' frequently asked questions regarding erectile dysfunction (ED), premature ejaculation (PE), Peyronie's disease (PD), male infertility, and other aspects of male sexual health were identified by authors. The recognition of question was evaluated ("yes" or "not"). For each recognized question, the response characteristics (domains) were rated on a scale from 0 to 10 (according to the quality). We chose the recognition rate of the questions as the primary outcome and the quality of the answers as the secondary outcome. Overall, the best VA in recognizing questions was Siri, with a total of 83.3% questions compared with 64.0% for Alexa (p = 0.024) and 74.0% for Google Assistant (p = 0.061). Siri was associated with a significantly higher recognition rate than Alexa for PE (80% vs. 40%; p = 0.002) and PD (66.7% vs. 33.3%; p = 0.010). The quality of the responses was classified as low in 57 out of 105 cases (54.3%), intermediate in 46 cases (43.8%), and high in only 2 cases (1.9%), highlighting an overall intermediate-low quality of the answers. Male infertility was the condition associated with the highest mean scores in "Targeted response to the problem" (7.32 ± 2.57), "Scientific correctness of the answer", (5.9 ± 2.76) "Completeness of the answer" (5.14 ± 2.56), and "Understandability of the response for a patient" (5.3 ± 2.51) domains. Siri was associated with significantly higher scores than Alexa (p < 0.05) in several domains of all conditions evaluated. The question recognition rate of VAs is quite high; however, the quality of the answers is still intermediate-low. Siri seems superior to Alexa in both question recognition and response quality. Male infertility appears to be the sexual dysfunction best addressed by VAs.

A Novel Low-Cost Uroflowmetry for Patient Telemonitoring.

Uroflowmetry (UF) is a crucial guideline-recommended tool for men with benign prostatic obstruction (BPO). Moreover, UF is a helpful decision-making tool for the management of patients with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH). In the last few years, telemedicine and telehealth have increased exponentially as cost-effective treatment options for both patients and physicians. Telemedicine and telehealth have been well positioned during the COVID-19 pandemic to prevent healthcare system overload and to ensure adequate management of patients through screening, diagnosis, and follow-up at home. In the present manuscript, the main characteristics and performance of a novel and low-cost device for home-based UF have been analyzed. The simple weight-transducer method has been applied to perform UF. An inexpensive load cell connected to a 24 bit analogic digital converter (ADC) sends data to a cloud server via SIM card or home Wi-Fi. Data are processed and shown in graphics with both volume and flow rate as a function of time, allowing for measurement of average flow rate, maximum flow rate, voided volume, and voiding time. A numerical algorithm allows for filtering of the dynamic effect due to the urine gravity acceleration and for removing the funnel to simplify the home measurement procedure. Through an online platform, the physician can see and compare each UF data. The device's reliability has been validated in a first laboratory setting and showed excellent performance. This approach based on domiciliary tests and an online platform can revolutionize the urologic clinic landscape by offering a constant patient cost-effective follow-up, eliminating the time wasted waiting in the office setting.

The Efficacy of Flogofilm® in the Treatment of Chronic Bacterial Prostatitis as an Adjuvant to Antibiotic Therapy: A Randomized Prospective Trial.

INTRODUCTION: Bacterial prostatitis (BP) is a common prostatic infection characterized by a bimodal distribution in young and older men, with a prevalence between 5-10% among all cases of prostatitis and a high impact on quality of life. Although the management of bacterial prostatitis involves the use of appropriate spectrum antibiotics, which represent the first choice of treatment, a multimodal approach encompassing antibiotics and nutraceutical products in order to improve the efficacy of chosen antimicrobial regimen is often required. OBJECTIVE: To evaluate the efficacy of Flogofilm® in association with fluoroquinolones in patients with chronic bacterial prostatitis (CBP). METHODS: Patients diagnosed with prostatitis (positivity to Meares-Stamey Test and symptoms duration > 3 months) at the University of Naples "Federico II", Italy, from July 2021 to December 2021, were included in this study. All patients underwent bacterial cultures and trans-rectal ultrasounds. Patients were randomized into two groups (A and B) receiving antibiotic alone or an association of antibiotics plus Flogofilm® tablets containing Flogomicina® for one month, respectively. The NIH-CPSI and IPSS questionnaires were administered at baseline, four weeks, twelve and twenty-four weeks. RESULTS: A total of 96 (Group A = 47, Group B = 49) patients concluded the study protocol. The mean age was comparable, with a mean age of 34.62 ± 9.04 years for Group A and 35.29 ± 10.32 years for Group B (p = 0.755), and IPSS at the baseline was 8.28 ± 6.33 and 9.88 ± 6.89 (p = 0.256), respectively, while NIH-CPSI at baseline was 21.70 ± 4.38 and 21.67 ± 6.06 (p = 0.959), respectively. At 1, 3 and 6 months, the IPSS score was 6.45 ± 4.8 versus 4.31 ± 4.35 (p = 0.020), 5.32 ± 4.63 versus 3.20 ± 3.05 (p = 0.042) and 4.91 ± 4.47 versus 2.63 ± 3.28 (p = 0.005) for Groups A and B, respectively. Similarly, the NIH-CPSI total score at 1, 3 and 6 months was 16.15 ± 3.31 versus 13.10 ± 5.03 (p < 0.0001), 13.47 ± 3.07 versus 9.65 ± 4.23 (p < 0.0001) and 9.83 ± 2.53 versus 5.51 ± 2.84 (p < 0.0001), respectively. CONCLUSIONS: Flogofilm®, associated with fluoroquinolones, demonstrate a significant improvement in pain, urinary symptoms and quality of life in patients affected by chronic bacterial prostatitis in both IPSS and NIH-CPSI scores compared with fluoroquinolones alone.

A misdiagnosis of mesh extrusion treated as a psychiatric female pelvic pain.

INTRODUCTION: Complications due to prosthetic surgery with mesh implantation may be misunderstood due to the insidious clinical presentation and inexperience of many surgeons if not adequately trained for the purpose. CASE REPORT: A 45-year-old female underwent a trans obturator tape procedure to correct severe stress urinary incontinence 3 months after surgery she developed urethral pain. The sling was partially removed, but the pain persisted. No residue sling was visualized by cystoscopies after surgery, and the pain was attributed to a psychiatric problem. She was treated with opioids, pregabalin without improvement of pain, until an extrusion of the sling into the urethra has been diagnosed by a careful urethrocystoscopy. CONCLUSION: It has been treated in our department by the removal of the residual sling, plus urethroplasty. The patient was followed up at 6 months with resolution of the painful symptoms.

Could the vaginal wall sling still have a role after FDA's warning? the functional outcomes at 20 years.

Introduction: Aims of this study were to evaluate the functional outcomes of a vaginal wall sling technique in patients with stress urinary incontinence at 20 years after surgery and to evaluate the patient's satisfaction after the surgical procedure. Material and Methods: This was a prospective single-center study on patients with stress urinary incontinence who underwent in situ vaginal sling surgery. Presurgery evaluation included history, pelvic examination, and urodynamic test. All patients completed Urogenital Distress Inventory-6 (UDI-6) questionnaire. They underwent checkups at 1, 3, 6, and 12 months postoperatively and then annually. The sling was created by making a rectangle (15-20 × 25 mm) on the anterior vaginal wall and it was reinforced by one roll of Marlex mesh on each side of the sling. The sutures were passed through the vagina at the suprapubic level after suprapubic incision, above the rectus fascia and tied without excessive tension. Results: From May 1996 to May 2002, 40 women underwent vaginal wall sling surgery for stress urinary incontinence. Last visit was performed on 20 women between March 2020 and April 2020. Median follow-up was 251.3 months (20.9 years) (range = 204.3-285.4 months). The success rate after 5 years of surgical procedure was 80%; over 5 years, the objective cure rate was 45%. Considering only the group of 13 patients with pure stress urinary incontinence, the objective cure rate decreased to 38%, in particular 7 years after surgery. Women who did not resolve their urinary incontinence needed to undergo a new treatment. At over 5 years after surgery, there was an increase in urgency (p = 0.001) and voiding symptoms (p = 0.008) and urgency urinary incontinence (UUI) (p = 0.04). Ninety-five percent were very much worse or much worse according to the Patient Global Impression of Improvement (PGI-I) scale. Conclusion: The in situ vaginal wall sling does not guarantee good long-term functional outcomes in women with stress urinary incontinence.

Novel Antimicrobial Strategies to Prevent Biofilm Infections in Catheters after Radical Cystectomy: A Pilot Study.

Catheter-associated infections in bladder cancer patients, following radical cystectomy or ureterocutaneostomy, are very frequent, and the development of antibiotic resistance poses great challenges for treating biofilm-based infections. Here, we characterized bacterial communities from catheters of patients who had undergone radical cystectomy for muscle-invasive bladder cancer. We evaluated the efficacy of conventional antibiotics, alone or combined with the human ApoB-derived antimicrobial peptide r(P)ApoBLAla, to treat ureteral catheter-colonizing bacterial communities on clinically isolated bacteria. Microbial communities adhering to indwelling catheters were collected during the patients' regular catheter change schedules (28 days) and extracted within 48 h. Living bacteria were characterized using selective media and biochemical assays. Biofilm growth and novel antimicrobial strategies were analyzed using confocal laser scanning microscopy. Statistical analyses confirmed the relevance of the biofilm reduction induced by conventional antibiotics (fosfomycin, ceftriaxone, ciprofloxacin, gentamicin, and tetracycline) and a well-characterized human antimicrobial peptide r(P)ApoBLAla (1:20 ratio, respectively). Catheters showed polymicrobial communities, with Enterobactericiae and Proteus isolates predominating. In all samples, we recorded a meaningful reduction in biofilms, in both biomass and thickness, upon treatment with the antimicrobial peptide r(P)ApoBLAla in combination with low concentrations of conventional antibiotics. The results suggest that combinations of conventional antibiotics and human antimicrobial peptides might synergistically counteract biofilm growth on ureteral catheters, suggesting novel avenues for preventing catheter-associated infections in patients who have undergone radical cystectomy and ureterocutaneostomy.

Psychological impact of abnormally invasive placenta: an underestimated and hidden morbidity.

OBJECTIVES: To evaluate anxiety and psychological impact of abnormally invasive placenta (AIP) diagnosis during pregnancy. METHODS: A cross-sectional survey study was performed to assess the psychological response of pregnant women with an antenatally AIP diagnosis. The psychological impact was measured through a visual analogue scale (VAS) for anxiety, which ranged from 0 (not at all anxious) to 100 (extremely anxious) and was referred to three questions: (1) How anxious were you the first time they counselled you about AIP?; (2) How anxious were you the day of the planned cesarean delivery in terms of morbidity/mortality?; (3) How anxious were you in terms of future sexual activities? RESULTS: 48 singleton pregnancies that underwent planned cesarean hysterectomy for AIP, met the inclusion criteria and were surveyed for the study. Mean VAS was 41.6 ± 25.6, with 47.9% of women with VAS >50 for question 1 (p=0.015). Mean VAS was 52.9 ± 19.1, with 75.0% of women with VAS >50 for question 2 (p=0.02). Mean VAS was 49.6 ± 20.4, with 83.3% of women with VAS >50 for question 3 (p=0.006). CONCLUSIONS: More than half of pregnant women with an antenatally AIP diagnosis reported a high VAS score regarding anxiety, in particular when morbidity/mortality and long-term consequences on sexual activities were analyzed. Our findings could be used to formulate timely psychological interventions to improve mental health and psychological resilience in women with AIP.

Use of penile shear wave elastosonography for the diagnosis of Peyronie's Disease: a prospective case-control study.

BACKGROUND: To evaluate the stiffness of the tunica albuginea (TA), we used a new noninvasive diagnostic technique called shear wave elastography (SWE). We determined whether SWE values are correlated with the degree of penile curvature, the time of disease onset, and pain severity experienced by patients during erection. This study analyzed the elasticity of the TA of patients with Peyronie's disease compared to that of the control group. We also analyzed any correlations between the stiffness of the cavernous bodies and the degree of curvature, time from diagnosis to curvature onset, and erectile pain severity. This was a prospective case-control study involving 100 men enrolled from September 2020 to August 2021. Participants were divided into group A (case group, n = 50), which included men with PD, with or without pain, and with penile curvature, or group B (control group, n = 50), which included healthy patients older than 18 years who visited the urology clinic for reasons other than PD. The medical history was collected for all patients who also underwent objective examination, B-mode ultrasound evaluation, and SWE. The International Index of Erectile Function (IIEF-15) visual analog scale (VAS) questionnaire was administered to all participants. RESULTS: There were no significant between-group differences regarding age, weight, and height (p > 0.05); however, there was a significant difference in the stiffness values (p < 0.05). An inverse correlation was observed between stiffness and the VAS score (p < 0.0001). A positive correlation was observed between the degree of curvature (p < 0.0001) and the time of curvature onset (p < 0.0001). The IIEF-15 scores were poorer in group A than in group B (p < 0.0001). CONCLUSION: SWE is an inexpensive, noninvasive method that can be used to measure the stiffness of PD patients.

RéSUMé: CONTEXTE: Pour évaluer la rigidité de la tunique albuginée (TA), nous avons utilisé une nouvelle technique de diagnostic non invasive, appelée élastographie par ondes de cisaillement (EOC). Nous avons déterminé si les valeurs de EOC étaient corrélées avec le degré de courbure du pénis, le moment d'apparition de la maladie de Lapeyronie (MP) et la gravité de la douleur ressentie par les patients pendant l'érection. Cette étude a analysé l'élasticité de la TA des patients atteints de MP par rapport à celle d'un groupe témoin. Nous avons également recherché toute corrélation entre la rigidité des corps caverneux et le degré de courbure, le temps écoulé entre le diagnostic et l'apparition de la courbure, et la gravité de la douleur érectile. Il s'agit d'une étude cas-témoins prospective impliquant 100 hommes enrôlés de septembre 2020 à août 2021. Les participants ont été assignés au groupe A (cas, n = 50), qui comprenait des hommes atteints de MP, avec ou sans douleur, et présentant une courbure du pénis, ou au groupe B (témoins, n = 50), qui comprenait des patients en bonne santé âgés de plus de 18 ans qui venaient à la clinique d'urologie pour des raisons autres que la MP. Les antécédents médicaux ont été recueillis pour tous les patients qui ont également subi un examen objectif, une évaluation échographique en mode B et une EOC. Le questionnaire de l'échelle visuelle analogique (EVA) de l'Indice international de la fonction érectile (IIEF-15) a été administré à tous les participants. RéSULTATS: Il n'y avait pas de différences significatives entre les groupes en ce qui concerne l'âge, le poids et la taille ; toutefois, il y avait une différence significative dans les valeurs de rigidité (p<0,05). Une corrélation inverse a été observée entre la rigidité et le score EVA (p<0,0001). Une corrélation positive a été observée entre le degré de courbure (p<0,0001) et le moment de l'apparition de la courbure (p<0,0001). Les scores IIEF-15 étaient plus faibles dans le groupe A que dans le groupe B (p<0,0001). CONCLUSIONS: L'élastographie par ondes de cisaillement (EOC) est une méthode peu coûteuse et non invasive qui peut être utilisée pour mesurer la rigidité des patients atteints de MP.

A Framework of Analysis to Facilitate the Harmonization of Multicenter Radiomic Features in Prostate Cancer.

Pooling radiomic features coming from different centers in a statistical framework is challenging due to the variability in scanner models, acquisition protocols, and reconstruction settings. To remove technical variability, commonly called batch effects, different statistical harmonization strategies have been widely used in genomics but less considered in radiomics. The aim of this work was to develop a framework of analysis to facilitate the harmonization of multicenter radiomic features extracted from prostate T2-weighted magnetic resonance imaging (MRI) and to improve the power of radiomics for prostate cancer (PCa) management in order to develop robust non-invasive biomarkers translating into clinical practice. To remove technical variability and correct for batch effects, we investigated four different statistical methods (ComBat, SVA, Arsynseq, and mixed effect). The proposed approaches were evaluated using a dataset of 210 prostate cancer (PCa) patients from two centers. The impacts of the different statistical approaches were evaluated by principal component analysis and classification methods (LogitBoost, random forest, K-nearest neighbors, and decision tree). The ComBat method outperformed all other methods by achieving 70% accuracy and 78% AUC with the random forest method to automatically classify patients affected by PCa. The proposed statistical framework enabled us to define and develop a standardized pipeline of analysis to harmonize multicenter T2W radiomic features, yielding great promise to support PCa clinical practice.

A Comparative Study of the Triglycerides/HDL Ratio and Pseudocholinesterase Levels in Patients with Bladder Cancer.

BACKGROUND: Lipid alterations may serve as potential tumour biomarkers. The ratio of triglycerides to HDL cholesterol (TG/HDL ratio) is associated with various cancers. Pseudocholinesterase (PChE) activity, involved in TG hydrolysis, plays an important role in the metabolism of lipoprotein. There is scarce data assessing the reliability of both the TG/HDL ratio and PChE levels in correctly classifying patients suffering from bladder cancer. METHODS: Three hundred and ninety-six patients undergoing cystoscopy or transurethral resection of the bladder (TURB), broken into two major groups, i.e., patients with histologically confirmed, non-metastatic bladder cancer (n = 208) and without bladder cancer (no bladder cancer, n = 188), formed the study population. The last group was split into two subgroups consisting of a cohort of patients never suffering from bladder cancer but with other bladder diseases (no CaBD, n = 100) and another cohort formed by patients characterised by eradicated bladder cancer after TURB with no recurrence during a three-month follow-up (previous bladder cancer, n = 88). Pieces of information by both metabolic derangement (the presence of type 2 diabetes mellitus), hypertension and lipid profile were retrieved from patient records upon entry to the study. Sensitivity, specificity, areas under the ROC (AUROC) of the TG/HDL ratio, and PChE levels were used in diagnostic decision making. RESULTS: The TG/HDL ratio as well as PChE concentrations of bladder cancer patients were significantly different when compared to those with previous bladder cancer and the no CaBD patients (p = 0.023 and 0.0004, respectively). There was an independent role of both the TG/HDL ratio and PChE levels in predicting the presence of bladder cancer (OR: 1.22 and 0.99, respectively), but the reliability of the TG/HDL ratio (AUROC: 0.587) was superior to that of PChE levels (AUROC: 0.374). The AUROC of a new parameter resulting from the combination of the TG/HDL ratio with PChE levels showed a further increment in the discriminant power of the bladder cancer presence (0.6298), interestingly with a negative predictive value (89%) according to the Bayesian approach. The cut-off of the TG/HDL ratio, the main marker of the present study that better distinguishes bladder cancer from no bladder cancer patients, was 2.147. DISCUSSION AND CONCLUSIONS: The reliability of the TG/HDL ratio is based on the fact that this parameter likely mirrors the insulin resistance (IR) underlying bladder cancer patients. Furthermore, PChE levels evidence both IR and the associated non-alcoholic fatty liver disease. The TG/HDL ratio and PChE levels as well as their combined use could help physicians to assess/confirm the presence of this very common cancer, where early detection is important to ensure the best therapeutical approach.

Daily low-dose tadalafil may reduce the penile curvature progression rate in patients with acute Peyronie's disease: a retrospective comparative analysis.

The aim of this study was to evaluate the clinical outcomes of patients in acute phase of Peyronie's disease (PD) treated with daily low-dose of Tadalafil. An observational retrospective study involving patients in acute phase of PD with erectile dysfunction (ED) was designed. All subjects were offered Tadalafil 5 mg one tablet a day. Men who accepted treatment were compared to patients who refused Tadalafil. Penile curvature progression was chosen as the primary outcome. PD Questionnaire (PDQ) and IIEF-5 scores were selected as secondary outcomes. A total of 191 patients were included in the study (108 intervention vs. 83 control). Penile curvature progression rate was significantly lower in subjects taking Tadalafil at 12 weeks (25.9% vs. 39.7%, p = 0.042). Mean IIEF-5 score improved in the intervention group, becoming significantly higher compared to the observation group at 12 weeks (19.3 vs. 11.2 points, p < 0.001). Mean PDQ-Overall and PDQ-Penile Pain scores only improved in the intervention group and the statistically significant differences at baseline between groups became not statistically significant at 12 weeks (p = 0.001 vs. p = 0.232 and p < 0.001 vs. p = 0.078, respectively). Daily low-dose Tadalafil in patients with acute phase of PD seems to significantly reduce the penile curvature progression rate compared to observation, especially when it is administrated early. It also appears to improve erectile function and PD-related symptoms.
