Background/Objectives: Recently, the European Association of Urology (EAU) guidelines presented the EAU guidelines bot to assist urologists in the reading of the guidelines; however, to date, no external validation is available. The aim of our study is to assess the accuracy, completeness, and clarity of the guidelines bot in reading renal transplantation guidelines and clinical cases. Methods: A total of 103 questions derived from the recommendations included in the EAU guidelines on renal transplantation, together with 10 distinct clinical scenarios, were created. Each question and clinical case was submitted to the EAU guidelines bot, and the corresponding responses were independently evaluated by two expert urologists in terms of accuracy, completeness, and clarity. Each domain was scored using a 5-point Likert scale. In cases of disagreement between the two reviewers, a third urologist was consulted. Accuracy, completeness, and clarity were analyzed for the clinical cases and per chapter and grade of recommendation for the questions. Results: Overall, 103 questions were generated. Regarding accuracy, 101/103 responses (98%) were classified as accurate, corresponding to scores of 4–5, whereas 2/103 responses (2%) showed fair accuracy, corresponding to a score of 3. No responses were considered inaccurate, defined as a score of 1–2. In terms of completeness, 101/103 responses (98%) were judged to be complete, with scores of 4–5, while 2/103 responses (2%) were rated as fairly complete, with a score of 3. No responses were classified as incomplete. With regard to clarity, 102/103 responses (99%) were considered clear, corresponding to scores of 4–5, whereas 1/103 response (1%) was rated as fairly clear, with a score of 3. No responses were deemed unclear. No significant differences were observed when comparing responses related to strong versus weak recommendations. For the clinical scenarios, 8/10 responses (80%) were rated as accurate, with scores of 4–5, while 2/10 responses (20%) showed fair accuracy, with a score of 3. Regarding completeness, all 10 responses (100%) were classified as fairly complete, corresponding to a score of 3. Finally, in terms of clarity, 8/10 responses (80%) were judged to be clear, with scores of 4–5, whereas 2/10 responses (20%) were rated as fairly clear, with a score of 3. Conclusions: The EAU guidelines bot represents an accurate tool for renal transplantation. Besides some occasional inaccuracies the bot is an excellent tool for urologists, especially to clarify doubt about the EAU guidelines. At the same time, it can give good support when facing a clinical case.

Background/Objectives: Recently the European Association of Urology (EAU) guidelines presented the EAU Guidelines bot to assist urologists in the reading of the guidelines; however, there is a lack of up-to-date external validation. The aim of our study is to assess the accuracy, completeness, and clarity of the guidelines bot in urethral strictures. Methods: A total of 117 questions based on the EAU urethral strictures guidelines recommendations were developed. Each question was input to the EAU guidelines bot and the response was assessed by two expert urologists to assess the accuracy, completeness, and clarity. Moreover, 10 simple clinical cases were input. A 5-point Likert scale was used as a score and, in case of discrepancies, a third urologist was queried. Accuracy, completeness and clarity were assessed per chapter and per grade of recommendation. All questions and answers were recorded in an Excel file. Results: Overall 117 questions were developed. In terms of accuracy, 111/117 (95%) were defined as accurate (scores 4–5), 4/117 (3%) presented a fair accuracy (score 3), and 2/117 (2%) were deemed not accurate. In terms of completeness, 93/117 (80%) were defined as complete (scores 4–5), 22/117 (19%) presented a fair completeness (score 3), and 2/117 (2%) were deemed not complete. Finally, in terms of clarity, 104/117 (89%) were defined as clear (scores 4–5), 13/117 (11%) presented a fair clarity (score 3), and 0/109 (0%) were deemed not clear. When comparing strong and weak recommendations, no differences were recorded. Overall the answers to simple clinical cases were in line with the guidelines with good accuracy, completeness and clarity scores. Conclusions: The EAU guidelines bot represents an accurate tool for urethral stenosis guidelines. Some fine-tuning is needed to improve readability and clarity.

Background: The aim of this study was to evaluate treatment satisfaction and decision regret in patients undergoing minimally invasive surgical therapies (MISTs) for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Materials and Methods: We analyzed prospectively collected data from consecutive patients undergoing MISTs across five Italian primary care urology centers. All patients underwent a comprehensive clinical assessment, including detailed medical history and physical examination. Preoperative, perioperative, and postoperative variables were recorded. Decision regret was assessed using validated questionnaires, with significant regret defined as a score >25%. Results: A total of 155 patients were included, with a median age of 64 years (IQR 58–66) and a median IPSS of 23 (IQR 18–26). Among them, 90 patients (51%) underwent Aquablation, 21 (12%) received a temporary implantable nitinol device (iTIND), 26 (15%) underwent water vapor thermal therapy (WVTT), and 37 (21%) were treated with prostatic urethral lift (PUL). The overall median decision regret score was 0 (IQR 0–15), with 23 patients (15%) reporting significant regret (>25%). Higher regret rates were observed in patients treated with PUL and WVTT compared to those undergoing iTIND and Aquablation. None of the evaluated variables—including age, BMI, prostate volume, preoperative Qmax, or preoperative IPSS—were significantly associated with treatment regret. However, although not reaching statistical significance, a prostate volume >60 cc was associated with higher regret in patients undergoing WVTT (OR = 3.33) and PUL (OR = 4.2). Conclusions: Among patients undergoing MISTs, treatment regret is not negligible and appears higher when patient selection is suboptimal. Larger studies are warranted to better identify predictors of decision regret and optimize patient selection for these procedures.

Objective: To provide an updated national overview of the clinical management of congenital and acquired penile curvature (PC) in Italy, evaluating current diagnostic and therapeutic practices among Italian urologists.Materials and methods: A 23-item anonymous digital survey was distributed by the Italian Society of Urology (SIU) to 2034 affiliated urologists between 2024 and 2025. The survey includes demographic data, diagnostic approaches, and treatment strategies for PC, including Peyronie’s disease (PD). Participants were categorized by practice setting and geographic region. SPSS software was used to conduct descriptive and comparative analyses.Results: Overall, 442 urologists had completed the survey (response rate: 21.7%). Most participants were affiliated either with university hospitals (34.6%) or public non-university hospitals (32.8%). The major incidence of PD cases, as reported by 310 (70.1%) respondents, were in patients between 45-60 years old and the most frequent presentation was a dorsal curvature (223 responses, 50.5%). The routine clinical practice, as reported by respondents, includes anamnestic data with photographs collection and penile ultrasound (in 261 (59%) and 188 (42.5%) of respondents, respectively), while penile dynamic CCDU was mainly used in patients with erectile dysfunction. In regard to therapeutic strategies, 142 (32.8%) of urologists used Clostridium Collagenase Histolyticum (CCH) for intralesional therapy; a similar proportion used verapamil/nicardipine, despite limited supporting evidence. Interestingly, surgical approaches varied widely: tunica plication was preferred in non-complex cases by 169 (38.2%), while penile prosthesis was offered in complex cases by 129 (29.2%) urologists. Finally, penile prosthesis implantation was offered in patients with severe ED unresponsive to pharmacological therapy, regardless of penile curvature only by 176 respondents (39.8%), meanwhile, 177 respondents considered penile prothesis only for severe PC over >60 degrees associated with ED.Conclusions: This nationwide survey reveals a significative heterogeneity in PC and PD management in Italy, with frequent reliance on off-label treatments and variable adherence to international guidelines. Economic limitations and regional differences appear to be a primary factor influencing clinical decisions and clinical practice. These findings underline the need for a major dissemination of evidence-based guidelines associated with national healthcare strategies aimed at standardized care and improving patient outcomes.

Background and Objectives: Totally endophytic renal tumors are a unique subset that pose significant technical challenges during partial nephrectomy (PN). The aim of this study was to evaluate the perioperative, oncologic, and functional outcomes of PN in this particular setting. Materials and Methods: We retrospectively evaluated 4151 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORD 2 project). Only patients treated with PN for entirely endophytic renal tumor were considered for final analyses. Results: A total of 211 patients were included, with a median PADUA score of 10 (IQR 9-11). Open, laparoscopic, and robotic approaches were used in 94 (44.5%), 52 (24.6%), and 65 (30.8%) cases, respectively. While surgical approach did not impact complication rates, robotic PN had significantly lower median blood loss (100 vs. 185 vs. 175 cc, p = 0.04) and shorter operative time (126 vs. 140 vs. 160 min, p = 0.01) compared to open and laparoscopic PN. At a median follow-up of 36.3 months (IQR 21.9–49.2), recurrence-free survival was 93.8%. Median %eGFR drop at 24 months was 12.1 (IQR 5.1–21.9), with significant eGFR loss (≥25%) in 36 (17.1%) patients. The robotic approach was associated with a lower %eGFR drop at 1-month and 1-year evaluations, but the benefit diminished at 24 months. Multivariate analysis showed age and open surgery as independent predictors of renal function loss at 1 month and Trifecta failure. Conclusions: The conservative management of entirely endophytic renal tumors is associated with favorable functional and oncologic outcomes. Whenever technically feasible, conservative surgery should be prioritized to optimize early renal function recovery.

Background: Posterior urethral valves (PUVs) represent the most common cause of male congenital lower urinary tract obstruction, often responsible for renal dysplasia and chronic renal failure. Despite recent improvements in patients’ outcomes thanks to prenatal ultrasound early diagnosis, PUVs can still impact sexual function and fertility. This study aims to review the available evidence on fertility in PUV patients, examining paternity rates and semen parameters. Methods: A review was conducted of the PubMed, Cochrane, Scopus, and Embase databases. Studies focusing on fertility and paternity outcomes in PUV patients were selected, including case reports, case series, and retrospective and prospective studies. Results: A total of 15 studies met the inclusion criteria. The review revealed that PUV patients often exhibit compromised semen parameters, including low sperm count, reduced motility, and abnormal morphology, as well as alterations in seminal plasma. PUV diagnoses are common in adults exhibiting infertility and ejaculation disorders, suggesting PUVs cannot be considered only a pediatric disease. Paternity rates among PUV patients were rarely reported in extenso, hampering the correct assessment of the overall medium paternity rate and its comparison with that of healthy individuals. Lastly, seminal parameters were assessed in a minimal cohort of patients, therefore, they could not be considered representative. Conclusions: Fertility and seminal parameters in PUV patients represent an under-investigated area. PUVs can variably and non-univocally affect fatherhood, and they may be associated with compromised semen quality. Early intervention and long-term follow-up are essential to address potential fertility issues. Future research should focus on developing targeted strategies to preserve and enhance fertility in this patient population.

Background: Nowadays, thanks to the introduction of the VI-RADS scoring system, mpMRI has shown promising results in pre-TURBT assessment of muscular invasiveness of BCa, even if its application in everyday practice is still limited. This might be due to a lack in the literature about the learning curve of radiologists and about the characteristics of the exam. With the aim to reduce scan time and patient discomfort while maintaining diagnostic accuracy, bpMRI has been introduced as a possible alternative to mpMRI in this group of patients. This study reports a single-center experience using mpMRI and the VI-RADS scoring system to differentiate NMIBC from MIBC. The primary aim of the study is to assess diagnostic accuracy of mpMRI using the VI-RADS scoring system. The secondary aim is to evaluate the learning curve of an experienced mpMRI radiologist. Additionally, we perform a retrospective assessment of the same group of patients evaluating only DWIs and T2-weighted images, as they underwent bpMRI, to compare the performance of mpMRI and bpMRI. Materials and Methods: From 11/2021 to 11/2023, patients with suspected newly diagnosed BCa were enrolled in this prospective study. All patients underwent mpMRI prior to TURBT in a highly specialized radiology center for MRI. According to VI-RADS, a cutoff of ≥3 was assumed to define MIBC. Histological TURBT reports were compared with preoperative VI-RADS scores to assess the accuracy of mpMRI in discriminating between NMIBC and MIBC. Furthermore, to assess the learning curve of the reading radiologist we analyzed the rate of patients correctly classified as MIBC at MRI. Finally, we evaluated the performance of a hypothetic biparametric MRI in classifying our cohort according to VI-RADS score and compared it with mpMRI performance by using DeLong’s test. Data analysis was performed using Jamovi software v.2.3 and R software v.4.2.1. Results: A total of 133 patients were enrolled. mpMRI showed sensitivity and specificity of 86% (95% confidence interval [CI]: 64–97) and 95% (95% CI: 89–98), respectively. The learning curve analysis of the reading radiologist showed that the rate of patients correctly classified as MIBC rapidly increases reaching its plateau after 40 cases. The hypothetic bpMRI showed a sensitivity of 76% (95% CI: 53–92) and a specificity of 93% (95% CI: 86–97), with no significant difference with mpMRI performance (p = 0.10). Conclusions: Our study confirms the effectiveness of MRI, particularly with the VI-RADS scoring system, in differentiating NMIBC from MIBC. The learning curve analysis underscores the importance of radiologist training in optimizing diagnostic accuracy. Future research should focus on enhancing the sensitivity of bpMRI and further validating these findings in larger and multicentric studies.
