We use direct $N$-body simulations to explore some possible scenarios for the future evolution of two massive clusters observed toward the center of NGC\,4654, a spiral galaxy with mass similar to that of the Milky Way. Using archival HST data, we obtain the photometric masses of the two clusters, $M=3\times 10^5$ M$_\odot$ and $M=1.7\times 10^6$ M$_\odot$, their half-light radii, $R_{\rm eff}\sim4$ pc and $R_{\rm eff} \sim 6$ pc, and their projected distances from the photometric center of the galaxy (both $, 10 Pages, 11 Figures, 2 Tables.

Our Galaxy and the nearby Andromeda Galaxy (M31) form a bound system, even though the relative velocity vector of M31 is currently not well constrained. Their orbital motion is highly dependent on the initial conditions, but all the reliable scenarios imply a first close approach in the next 3-5 Gyrs. In our study, we simulate this interaction via direct N-body integration, using the HiGPUs code. Our aim is to investigate the dependence of the time of the merger on the physical and dynamical properties of the system. Finally, we study the dynamical evolution of the two Supermassive Black Holes placed in the two galactic centers, with the future aim to achieve a proper resolution to follow their motion until they form a tight binary system., Proceedings of IAU Symposium No. 351, 2019A, (MODEST-19), "Star Clusters: From the Milky Way to the Early Universe".

Our Galaxy and the nearby Andromeda galaxy (M31) are the most massive members of the Local Group, and they seem to be a bound pair, despite the uncertainties on the relative motion of the two galaxies. A number of studies have shown that the two galaxies will likely undergo a close approach in the next 4$-$5 Gyr. We used direct $N$-body simulations to model this interaction to shed light on the future of the Milky Way - Andromeda system and for the first time explore the fate of the two supermassive black holes (SMBHs) that are located at their centers. We investigated how the uncertainties on the relative motion of the two galaxies, linked with the initial velocities and the density of the diffuse environment in which they move, affect the estimate of the time they need to merge and form ``Milkomeda''. After the galaxy merger, we follow the evolution of their two SMBHs up to their close pairing and fusion. Upon the fiducial set of parameters, we find that Milky Way and Andromeda will have their closest approach in the next 4.3 Gyr and merge over a span of 10 Gyr. Although the time of the first encounter is consistent with other predictions, we find that the merger occurs later than previously estimated. We also show that the two SMBHs will spiral in the inner region of Milkomeda and coalesce in less than 16.6 Myr after the merger of the two galaxies. Finally, we evaluate the gravitational-wave emission caused by the inspiral of the SMBHs, and we discuss the detectability of similar SMBH mergers in the nearby Universe ($z\leq 2$) through next-generation gravitational-wave detectors., Comment: 8 Pages, 11 Figures, 1 Table.

IntroductionProstate-specific membrane antigen (PSMA) is a transmembrane protein expressed by normal prostatic tissue. Therefore, molecular imaging targeting PSMA (PSMA-PET) has gained particular interest and diffusion for PCa staging and restaging. Several factors may affect PSMA-PET results, and many tools have been proposed to improve patient selection. Furthermore, PSMA expression is not homogeneous among different tissues and within the prostate itself. The aims of this study were to evaluate immunohistochemistry (IHC) features of prostate biopsy samples and to assess their correlation with whole-mount specimens and PSMA-PET parameters.MethodsWe included consecutive high-risk PCa patients who underwent PSMA-PET for staging proposal at our institution from January 2022 to December 2022. The PET parameters selected were SUVmax, total volume (TV), and total lesion activity (TL). Each patient underwent multiparametric MRI (mpMRI) and fusion-targeted prostate biopsy prior to surgery. IHC analyses were performed on the index lesion cores. IHC visual score (VS) (1, 2, 3) and visual pattern (VP) (membranous, cytoplasmic, and combined) and the percentage of PSMA-negative tumor areas (PSMA%neg) within biopsy cores were evaluated.ResultsForty-three patients who underwent robotic radical prostatectomy after PSMA-PET were available for analyses. Concordance between VS and VP at biopsy and final pathology showed a Cohen’s kappa coefficient of 0.39 and 0.38, respectively. Patients with PSMA%neg 20% on biopsy cores in terms of SUVmax, PSMA-TL, and PSMA-TV (p = 0.5, p = 0.5, and p = 0.9 respectively).ConclusionsWe found a correlation between IHC VS and VP on targeted biopsy cores and SUVmax at PSMA-PET. However, the correlation between the IHC parameters of biopsy cores and final pathology was not as high as expected. Nevertheless, the presence of PSMA%neg

BackgroundThe objective of this study was to assess the impact of age and other patient and treatment characteristics on toxicity in prostate cancer patients receiving adjuvant radiotherapy (RT).Materials and methodsThis observational study (ICAROS-1) evaluated both acute (RTOG) and late (RTOG/EORTC) toxicity. Patient- (age; Charlson’s comorbidity index) and treatment-related characteristics (nodal irradiation; previous TURP; use, type, and duration of ADT, RT fractionation and technique, image-guidance systems, EQD2 delivered to the prostate bed and pelvic nodes) were recorded and analyzed.ResultsA total of 381 patients were enrolled. The median EQD2 to the prostate bed (α/β=1.5) was 71.4 Gy. The majority of patients (75.4%) were treated with intensity-modulated radiation therapy (IMRT) or volumetric-modulated arc therapy (VMAT). Acute G3 gastrointestinal (GI) and genitourinary (GU) toxicity rates were 0.5% and 1.3%, respectively. No patients experienced >G3 acute toxicity. The multivariable analysis of acute toxicity (binomial logistic regression) showed a statistically significant association between older age (> 65) and decreased odds of G≥2 GI acute toxicity (OR: 0.569; 95%CI: 0.329-0.973; p: 0.040) and decreased odds of G≥2 GU acute toxicity (OR: 0.956; 95%CI: 0.918-0.996; p: 0.031). The 5-year late toxicity-free survival rates for G≥3 GI and GU toxicity were 98.1% and 94.5%, respectively. The only significant correlation found (Cox’s regression model) was a reduced risk of late GI toxicity in patients undergoing hypofractionation (HR: 0.38; 95% CI: 0.18-0.78; p: 0.008).ConclusionsThe unexpected results of this analysis could be explained by a “response shift bias” concerning the protective effect of older age and by treatment in later periods (using IMRT/VMAT) concerning the favorable effect of hypofractionation. However, overall, the study suggests that age should not be a reason to avoid adjuvant RT and that the latter is well-tolerated even with moderately hypofractionated regimens.

In writing his wonderful poem, the Divine Comedy, Dante Alighieri described very precisely the structure of the three worlds visited in his journey. It is sure that the Poet saw, in his mind, concrete shapes and dimensions, and he tried, through his verses, to explain to us that the Hell, the Purgatory and the Heaven are real. Starting from several quantitative information included in the Comedy, it is possible to obtain physical features of the worlds imagined by Dante, such as the depth of the Hell, or the width of the circles, the height of the Purgatory and also the strange shape of the Heaven, impossible to describe with a three-dimensional geometry. Using elementary mathematical relations, I will show that the structure of the three kingdoms is consistent and, finally, I will point out Alighieri’s genius not only in term of poetical ability, but also on a scientific basis.

Background: Current literature does not provide large-scale data regarding clinical outcomes of robot-assisted (RAPN) versus open (OPN) partial nephrectomy. Moreover, data assessing predictors of long-term oncologic outcomes after RAPN are scarce. Objective: To compare perioperative, functional, and oncologic outcomes of RAPN versus OPN, and to investigate the predictors of oncologic outcomes after RAPN. Design, setting, and participants: This study included 3467 patients treated with OPN (n = 1063) or RAPN (n = 2404) for a single cT1–2N0M0 renal mass from 2004 to 2018 at nine high-volume European, North American, and Asian institutions. Outcome measurements and statistical analysis: The study outcomes were short-term postoperative, functional, and oncologic outcomes. Regression models investigated the effect of surgical approach (open vs Robot assisted) on study outcomes, and interaction tests were used for subgroup analyses. Propensity score matching for demographic and tumor characteristics was used in sensitivity analyses. Multivariable Cox-regression analyses identified predictors of oncologic outcomes after RAPN. Results and limitations: Baseline characteristics were similar between patients receiving RAPN and OPN, with only few differences. After adjusting for confounding, RAPN was associated with lower odds of intraoperative (odds ratio [OR]: 0.39, 95% confidence interval [CI]: 0.22, 0.68) and Clavien-Dindo ≥2 postoperative (OR: 0.29, 95% CI: 0.16, 0.50) complications (both p 0.05 on interaction tests). On multivariable analyses, we found no differences between the two techniques with respect to functional and oncologic outcomes (all p > 0.05). Overall, there were 63 and 92 local recurrences and systemic progressions, respectively, with a median follow-up after surgery of 32 mo (interquartile range: 18, 60). Among patients receiving RAPN, we assessed predictors of local recurrence and systemic progression with discrimination accuracy (ie, C-index) that ranged from 0.73 to 0.81. Conclusions: While cancer control and long-term renal function did not differ between RAPN and OPN, we found that the intra- and postoperative morbidity—especially in terms of complications—was lower after RAPN than after OPN. Our predictive models allow surgeons to estimate the risk of adverse oncologic outcomes after RAPN, with relevant implications for preoperative counseling and follow-up after surgery. Patient summary: In this comparative study on robotic versus open partial nephrectomy, functional and oncologic outcomes were similar between the two techniques, with lower morbidity—especially in terms of complications—for robot-assisted surgery. The assessment of prognosticators for patients receiving robot-assisted partial nephrectomy may help in preoperative counseling and provides relevant data to tailor postoperative follow-up.

This study aimed to assess the efficacy of a novel prophylactic scheme of fosfomycin trometamol in patients undergoing elective HoLEP (holmium laser enucleation of the prostate) or TURP (transurethral resection of the prostate) procedures for treating benign prostatic hyperplasia. Patients affected by benign prostatic hyperplasia and undergoing elective HoLEP or TURP procedures during the period February 2022–June 2023 were prospectively enrolled. Two 3 g oral fosfomycin trometamol doses 12 h apart were administered at 8.00 p.m. on day −1 (i.e., the day before HoLEP or TURP procedure) and at 8.00 a.m. on day 0 (i.e., the day of the surgical procedure). The following outcomes were assessed: prevalence of fever occurring in the first 48 h after surgical procedure; prevalence of urological complications occurring after the surgical procedure; prevalence of proven urinary tract infections (UTIs) and/or bloodstream infections (BSIs) at 14 days post-procedure; and prevalence of emergency department admission for UTI-related sepsis at 14 days post-procedure. Univariate analysis comparing patients with and without proven UTI, BSI, or emergency department admission at 14 days post-procedure was carried out. Overall, 96 patients (median age 70 years) undergoing HoLEP (82.3%) or TURP (17.7%) were prospectively included. Median (IQR) time of surgical procedure after the morning fosfomycin dose was 226.5 min (range 88.5–393.75 min). Fever in the post-surgical 48 h occurred in 3/96 patients (3.1%). Prevalence of proven UTI at 14 days was as low as 1.0% (1/96), whereas no patient had proven BSI or UTI-related sepsis requiring emergency department admission at 14 days. Our findings support the contention that a prophylactic scheme based on two doses of fosfomycin trometamol 12 h apart before surgical intervention may represent a valuable strategy for preventing infectious complications in urologic patients undergoing HoLEP or TURP. Larger definitive confirmatory studies are warranted.

The paper describes the components of an envisioned open source framework that supports several stages in the model-based development of two- and three-wheelers software controls. The proposed solution supports the runtime execution on an OSEK-compatible [8] real-time operating system for multicore platforms. The framework consists of a modeling and simulation tool (including hierarchical state machines) and a code generator for the development of the functional model of controls and the definition of their task implementation; an OSEK/AUT OSAR operating system and device driver stack; OS and I/O configuration tools. The platform has been released open-source under an industryfriendly license. Our framework is currently in use for the development of innovative two-three wheelers control systems at Piaggio. In this paper we describe the experience matured in the application development, the benefits and current limitations of the approach. In particular, the result of this study has been a demonstrator platform which includes a BLDC motor control written using the proposed framework.

This study aimed to examine the physical and mental Quality of Life (QoL) trajectories in prostate cancer (PCa) patients participating in the Pros-IT CNR study. QoL was assessed using the Physical (PCS) and Mental Component Score (MCS) of Short-Form Health Survey upon diagnosis and two years later. Growth mixture models were applied on 1158 patients and 3 trajectories over time were identified for MCS: 75% of patients had constantly high scores, 13% had permanently low scores and 12% starting with low scores had a recovery; the predictors that differentiated the trajectories were age, comorbidities, a family history of PCa, and the bowel, urinary and sexual functional scores at diagnosis. In the physical domain, 2 trajectories were defined: 85% of patients had constantly high scores, while 15% started with low scores and had a further slight decrease. Two years after diagnosis, the psychological and physical status was moderately compromised in more than 10% of PCa patients. For mental health, the trajectory analysis suggested that following the compromised patients at diagnosis until treatment could allow identification of those more vulnerable, for which a level 2 intervention with support from a non-oncology team supervised by a clinical psychologist could be of help.

Multiparametric magnetic resonance imaging (mpMRI) is currently the most effective diagnostic tool for detecting prostate cancer (PCa) and evaluating adenocarcinoma-mimicking lesions of the prostate gland, among which granulomatous prostatitis (GP) represents the most interesting diagnostic challenge. GP consists of a heterogeneous group of chronic inflammatory lesions that can be differentiated into four types: idiopathic, infective, iatrogenic, and associated with systemic granulomatous disease. The incidence of GP is growing due to the increase in endourological surgical interventions and the adoption of intravesical instillation of Bacillus Calmette-Guerin in patients with non-muscle invasive bladder cancer; therefore, the difficulty lies in identifying specific features of GP on mpMRI to avoid the use of transrectal prostate biopsy as much as possible.

Objectiveto evaluate the impact of 3D model for a comprehensive assessment of surgical planning and quality of partial nephrectomy (PN).Materials and methods195 patients with cT1-T2 renal mass scheduled for PN were enrolled in two groups: Study Group (n= 100), including patients referred to PN with revision of both 2D computed tomography (CT) imaging and 3D model; Control group (n= 95), including patients referred to PN with revision of 2D CT imaging. Overall, 20 individuals were switched to radical nephrectomy (RN). The primary outcome was the impact of 3D models-based surgical planning on Trifecta achievement (defined as the contemporary absence of positive surgical margin, major complications and ≤30% postoperative eGFR reduction). The secondary outcome was the impact of 3D models on surgical planning of PN. Multivariate logistic regressions were used to identify predictors of selective clamping and Trifecta’s achievement in patients treated with PN (n=175).ResultsOverall, 73 (80.2%) patients in Study group and 53 (63.1%) patients in Control group achieved the Trifecta (p=0.01). The preoperative plan of arterial clamping was recorded as clampless, main artery and selective in 22 (24.2%), 22 (24.2%) and 47 (51.6%) cases in Study group vs. 31 (36.9%), 46 (54.8%) and 7 (8.3%) cases in Control group, respectively (p

Abstract Background Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24 months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence. Methods We describe a protocol for an observational, prospective, multicenter, cohort study to assess patients affected by bladder neoplasms undergoing radical cystectomy and urinary diversion. The Italian Radical Cystectomy Registry is an electronic registry to prospectively collect the data of patients undergoing radical cystectomy conducted with any technique (open, laparoscopic, robotic-assisted). Twenty-eight urology departments across Italy will provide data for the study, with the recruitment phase between 1st January 2017-31st October 2020. Information is collected from the patients at the moment of surgical intervention and during follow-up (3, 6, 12, and 24 months after radical cystectomy). Peri-operative variables include surgery time, type of urinary diversion, conversion to open surgery, bleeding, nerve sparing and lymphadenectomy. Follow-up data collection includes histological information (e.g., post-op staging, grading, and tumor histology), short- and long-term outcomes (e.g., mortality, post-op complications, hospital readmission, sexual potency, continence etc). Discussion The current protocol aims to contribute additional data to the field concerning the short- and long-term outcomes of three different radical cystectomy surgical techniques for patients with bladder cancer, including open, laparoscopic, and robot-assisted. This is a comparative-effectiveness trial that takes into account a complex range of factors and decision making by both physicians and patients that affect their choice of surgical technique. Trial registration ClinicalTrials.gov , NCT04228198 . Registered 14th January 2020- Retrospectively registered.

Objective: The aim of the study was to evaluate the accuracy of multiparametric Magnetic Resonance Imaging (mpMRI) in the detection of local recurrence of prostate cancer (PCa) with the evaluation of the added value of signal Intensity/Time (I/T) curves. Materials and methods: A retrospective analysis of 22 patients undergoing mpMRI from 2015 to 2020 was carried out, with the following inclusion criteria: performing transrectal ultrasound guided biopsy within 3 months in the case of positive or doubtful findings and undergoing biopsy and/or clinical follow-up for 24 months in the case of negative results. The images were reviewed, and the lesions were catalogued according to morphological, diffusion-weighted imaging (DWI) and dynamic contrast- enhanced (DCE) features. Results: The presence of local recurrence was detected in 11/22 patients (50%). Greater diameter, hyperintensity on DWI, positive contrast enhancement and type 2/3 signal I/T curves were more frequently observed in patients with local recurrence (all p < 0.05). Of all the sequences, DCE was the most accurate; however, the combination of DCE and DWI showed the best results, with a sensitivity of 100%, a specificity of 82%, a negative predictive value of 100% and a positive predictive value of 85%. Conclusions: The utility of MRI in the detection of local recurrence is tied to the multiparametric approach, with all sequences providing useful information. A combination of DCE and DWI is particularly effective. Moreover, specificity could be additionally improved using analysis of the signal I/T curves.

Background and Objectives: The aim of this article is to present a single-surgeon, open retroperitoneal lymph node dissection (RPLND) series for testicular cancer in a high-volume center. Materials and Methods: We reviewed data from patients who underwent RPLND performed by an experienced surgeon at our institution between 2000 and 2019. We evaluated surgical and perioperative outcomes, complications, Recurrence-Free Survival (RFS), Overall Survival (OS), and Cancer-Specific Survival (CSS). Results: RPLND was performed in primary and secondary settings in 21 (32%) and 44 (68%) patients, respectively. Median operative time was 180 min. Median hospital stay was 6 days. Complications occurred in 23 (35%) patients, with 9 (14%) events reported as Clavien grade ≥ 3. Patients in the primary RPLND group were significantly younger, more likely to have NSGCT, had higher clinical N0 and M0, and had higher nerve-sparing RPLND (all p ≤ 0.04) compared to those in the secondary RPLND group. In the median follow-up of 120 (56–180) months, 10 (15%) patients experienced recurrence. Finally, 20-year OS, CSS, and RFS were 89%, 92%, and 85%, respectively, with no significant difference in survival rates between primary vs. secondary RPLND subgroups (p = 0.64, p = 0.7, and p = 0.31, respectively). Conclusions: Open RPLND performed by an experienced high-volume surgeon achieves excellent oncological and functional outcomes supporting the centralization of these complex procedures.

Introduction and Objective: ExactVuTM is a real-time micro-ultrasound system which provides, according to the Prostate Risk Identification Using Micro-Ultrasound protocol (PRI-MUS), a 300% higher resolution compared to conventional transrectal ultrasound. To evaluate the performance of ExactVuTM in the detection of Clinically significant Prostate Cancer (CsPCa). Materials and methods: Patients with Prostate Cancer diagnosed at fusion biopsy were imaged with ExactVuTM. CsPCa was defined as any Gleason Score ≥ 3+4. ExactVuTM examination was considered as positive when PRI-MUS score was ≥ 3. PRI-MUS scoring system was considered as correct when the fusion biopsy was positive for CsPCa. A transrectal fusion biopsy- proven CsPCa was considered as a gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the receiver operator characteristic (ROC) curve (AUC) were calculated. Results: 57 patients out of 68 (84%) had a csPCa. PRI-MUS score was correctly assessed in 68% of cases. Regarding the detection of CsPCa, ExactVuTM ’s sensitivity, specificity, PPV, and NPV was 68%, 73%, 93%, and 31%, respectively and the AUC was 0.7 (95% CI 0.5-0-8). For detecting CsPCa in the transition/ anterior zone the sensitivity, specificity, PPV, and NPV was 45%, 66%, 83% and 25% respectively ant the AUC was 0.5 (95% CI 0.2-0.9). Accounting only the CsPCa located in the peripheral zone, sensitivity, specificity, PPV, and NPV raised up to 74%, 75%, 94%, 33%, respectively with AUC 0.75 (95% CI 0.5-0-9). Conclusions: ExactVuTM provides high resolution of the prostatic peripheral zone and could represent a step forward in the detection of CsPCa as a triage tool. Further studies are needed to confirm these promising results.

The COVID-19 outbreak, in a few weeks, overloaded Italian hospitals, and the majority of medical procedures were postponed. During the pandemic, with hospital reorganization, clinical and learning activities performed by residents suffered a forced remodulation. The objective of this study is to investigate how urology training in Italy has been affected during the COVID-19 era. In this multi-academic study, we compared residents' training during the highest outbreak level with their previous activity. Overall 387 (67.1%) of the 577 Italian Urology residents participated in a 72-h anonymous online survey with 36 items sent via email. The main outcomes were clinical/surgical activities, social distancing, distance learning, and telemedicine. Clinical and learning activity was significantly reduced for the overall group, and after categorizing residents as those working only in COVID hospitals, both “junior” and “senior” residents, and those working in any of three geographical areas created (Italian regions were clustered in three major zones according to the prevalence of COVID-19). A significant decrease in outpatient activity, invasive diagnostic procedures, and endoscopic and major surgeries was reported. Through multivariate analysis, the specific year of residency has been found to be an independent predictor for all response modification. Being in zone 3 and zone 2 and having “senior” resident status were independent predictors associated with a lower reduction of the clinical and learning activity. Working in a COVID hospital and having “senior” resident status were independent predictors associated with higher reduction of the outpatient activity. Working in zone 3 and having “senior” resident status were independent predictors of lower and higher outpatient surgical activity, respectively. Working in a COVID hospital was an independent predictor associated with robotic surgical activity. The majority of residents reported that distance teaching and multidisciplinary virtual meetings are still not used, and 44.8% reported that their relationships with colleagues decreased. The COVID-19 pandemic presents an unprecedented challenge, including changes in the training and education of urology residents. The COVID era can offer an opportunity to balance and implement innovative solutions that can bridge the educational gap and can be part of future urology training.

Objective: To assess the economic impact of Holmium laser enucleation of prostate (HoLEP) in comparison with transurethral resection of prostate (TURP) and open prostatectomy (OP). Methods: Between January 2017 and January 2018, we prospectively enrolled 151 men who underwent HoLEP, TURP or OP at tertiary Italian center, due to bladder outflow obstruction symptoms. Patients with prostate volume ≤ 70 cc and those with prostate volume > 70 cc were scheduled for TURP or HoLEP and OP or HoLEP, respectively. Intraoperative and early post-operative functional outcomes were recorded up to 6 months follow up. Cost analysis was carried out considering direct costs (operating room [OR] utilization costs, nurse, surgeons and anesthesiologists’ costs, OR disposable products costs and OR products sterilization costs), indirect costs (hospital stay costs and diagnostics costs) and global costs as sum of both direct and indirect plus general costs related to hospitalization. Cost analysis was performed comparing patients referred to TURP and HoLEP with prostate volume ≤ 70 cc and men underwent OP and HoLEP with prostate volume > 70 cc respectively. Results: Overall, 53 (35.1%), 51 (33.7%) and 47 (31.1%) were scheduled to HoLEP, TURP and OP, respectively. Both TURP, HoLEP and OP proved to effectively improve urinary symptoms related to BPE. Considering patients with prostate volume ≤ 70 cc, median global cost of HoLEP was similar to median global cost of TURP (2151.69 € vs. 2185.61 €, respectively; p = 0.61). Considering patients with prostate volume > 70 cc, median global cost of HoLEP was found to be significantly lower than median global cost of OP (2174.15 € vs. 4064.97 €, respectively; p ≤ 0.001). Conclusions: Global costs of HoLEP are comparable to those of TURP, offering a cost saving of only 11.4 € in favor of HoLEP. Conversely, HoLEP proved to be a strong competitor of OP because of significant global cost sparing amounting to 1890.82 € in favor of HoLEP.

The COVID-19 outbreak dramatically changed hospital everyday life, impairing the course of previous routine activity, also in urology. In the next months, together with keeping the focus on the prevention of contagion recrudescence, the health care system will face another stringent issue, i.e. to restore all the services not COVID-related. Leonardi et al. in their paper report an equilibrate overview on the incoming “Phase 2”, in order to set up so-called COVID-free hospitals and departments. The authors offer an insight from a practical point of view, detailing protocols for any of the steps of the path of care, from the outpatient visit to surgery

Objective: Holmium laser has demonstrated high efficacy in urethral disobstruction. Venous air embolism (VAE) is a rare complication of prostate surgery. Only two cases of venous air embolism (VAE) in patients submitted to HoLEP, have been described. In this paper we show a third case of not fatal VAE after HoLEP. Materials and methods: A case of VAE occurred in holmium laser enucleation (HoLEP) due to obstructive lower urinary tract symptoms (LUTS) in a 70 years old patient. After the procedure, patient’s end tidal carbon dioxide (ETCO2) levels dramatically decreased at 17 mmHg, with pressure airway (PAW)16 mmHg; oxygen saturation level was at 75%, without any loss in the ventilation circuit and with arterial blood pressure of 94/54 mmHg. Due to the negativity for other suspicions, the suspect of VAE was postulated. Result: The immediate switching from laryngeal mask to Oro Tracheal Intubation increased the oxygen level. A cardiac transthoracic ultrasound was negative for air bubbles inside cardiac cavities, without any alteration in the cardiac kinetics. Arterial blood sample turned negative for any alteration compatible with VAE and catheter continuous vesical irrigation was started to obtain clear washing fluid without blood cloths. The extubated patient showed no neurological defects. Conclusions: An invasive monitoring system is the key to rapidly and correctly identify any embolic episode during this kind of surgery.

Introduction and aim: Radical Cystectomy (RC) with ileal urinary diversion is one of the most complex urological surgical procedure, and many Fast Track (FT) protocols have been described to reduce hospitalization, without increasing postoperatory complications. We present the one-year results of a dedicated protocol developed at a high volume centre. Materials and methods: The FT protocol was designed after a review of the literature and a multidisciplinary collegiate discussion, and it was applied to patients scheduled to open RC with intestinal urinary diversion. To validate its feasibility, we compared its results with data collected from a 1:1 matched population of patients who had undergone the same surgical procedure, without the implementation of the FT protocol. Results: We enrolled in the FT group 11 (55%) patients scheduled to RC with ileal conduit diversion, and 9 patients (45%) scheduled to orthotopic neobladder (Studer) substitution, while a numerically equivalent population was enrolled in the control group, matched according to age at surgery, BMI, gender, ASA score, CCI, preoperative stage and type of urinary diversion. No statistically significant difference was found in terms of pre-operatory and intra-operatory domains. Median overall age was 71 years (Inter Quartile Range - IQR: 63-76) and mean operatory time was 276 ± 57 minutes. Hospitalization time was significantly reduced in the FT group, considering oralization and canalization items we found a significant advantage in the FT group. No statistically significant difference was found in the control of the post-operatory pain. We found no difference, in terms of both early and late complications ratio, among the two populations. Complications graded Clavien ≥ 3 were found in 4 patients of the control group (20%), while in only one patient (5%) in the Fast Track group, though this difference was not statistically significant. Conclusions: The Fast Track protocol developed in this study has proven to be effective in significantly reducing hospitalization time in patients submitted to RC with intestinal urinary diversion, without increasing post-operatory complications ratio.

Introduction: Purpose of our study was to investigate the role of a negative in-bore MRI-guided biopsy (MRI-GB) in comparison to a negative multiparametric prostate MRI (mpMRI) and a contextual negative transrectal ultrasound guided biopsy of the prostate with regard to incidental prostate cancer findings in the surgical specimen of men who underwent to Holmium Laser enucleation of prostate (HoLEP) with a preoperative suspicion of prostate cancer. Materials and methods: Data of 117 of symptomatic patients for bladder outflow obstruction who subsequently underwent to HoLEP was retrospectively analyzed form a multicentric database. All patients had a raised serum PSA and/or an abnormal digital rectal examination (DRE) with a pre-interventional mpMRI. Prostate cancer was excluded either with an en-bore MRI-GB (group "IN-BORE MRI-GB" n = 57) in case of a suspect area at the mpMRI or with a standard biopsy (group "mpMRI + TRUS-GB" n = 60) in case of a negative mpMRI. Preoperative characteristic surgical and histological outcomes were analyzed. Univariate and multivariate logistic regression model was performed to investigate independent predictors of incidental Prostate Cancer (iPCa). Results: Both groups presented moderate to severe lower tract urinary symptoms: median IPSS was 19 (IQR: 17.0-22.0) in the IN-BORE MRI-GB group and 20 (IQR: 17.5-22.0) in the mpMRI + TRUS-GB (p = 0.71). No statistically significant difference was found between the two groups besides total prostate volume with 68 cc (IQR: 58.0-97.0) in the IN-BORE MRI-GB group and 84 cc (IQR: 70.0-115.0) in the mpMRI + TRU-GB group (p = 0.01) No differences were registered in surgical time, removed tissue, catheterization time, hospital stay and complications rate. No different rates (p = 0.50) of iPCa were found in the IN-BORE MRI-GB group (14%) in comparison with mpMRI + TRUS-GB group (10 %); pT stage and ISUP Grade Group in iPCa stratification were comparable between the two groups. In multivariate analysis a statistically significant correlation with age as an independent predictive factor of iPCa was found (OR 1.14; 95% CI: 1.02-1.27; p = 0.02) while no correlations were revealed with PSA (OR 1.12; 95% CI: 0.99-1.28; p = 0.08) and a negative in-bore MRI-GB (OR 1.72; 95% CI: 0.51-5.77; p = 0.37). Conclusions: Including a mpMRI and an eventual in-bore MRIGB represents a novel clinical approach before surgery in patients with symptomatic obstruction with a concomitant suspicion of PCa, leading to low rate of iPCa and avoiding unnecessary standard TRUS-GB biopsies

Background: Combination therapy with 5 alpha-reductase inhibitor (5-ARI) and alpha-blocker can be considered as a gold standard intervention for medical management of lower urinary tract symptoms related to benign prostatic hyperplasia (LUTS/BPH). On the other hand, 5-ARI monotherapy and in particular Finasteride alone is currently getting focus of attention especially due to lack of systematic reviews investigating efficacy outcomes and/or adverse events associated. Objectives: Aim of the present critical review was to analyze current knowledge of clinical efficacy and incidence of adverse events associated with 5-ARI treatment for LUTS/BPH. Materials and methods: A systematic review of clinical trials of the literature of the past 20 years was performed using database from PubMed, Cochrane Collaboration and Embase. A total of 8821 patients were included in this study and inclusion criteria for studies selection were: data from randomized clinical trials (RCTs) focusing their attention on the clinical role of Finasteride monotherapy for symptomatic BPH. Parameters of research included prostate specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPPS), postvoid residual urine (PVR), voiding symptoms of IPSS (voiding IPSS), maximum urinary flow rate (Qmax), and adverse events (AEs). Results: Overall 12 original articles were included and critically evaluated. Sample sizes of patient actively treated with finasteride varied from 13 to 1524 cases analyzed in a single study. Follow-up after treatments ranged from 3 to 54 months. The effect of finasteride in reducing prostate volume (PV) was moderate (standardized mean difference (SMD) effect between 0.5 to 0.8 for all trials evaluable) while the effect on IPSS score and Qmax was considered significant (SMD in the 0.2 to 0.5 variation range). No severe AEs and/or psychiatric disorders were retrieved among the studies. Sexual health dysfunctions were significantly influenced by finasteride therapy when compared with placebo treated patients. Conclusions: Although significant clinical benefits of finasteride monotherapy were demonstrated, the effective size of the available reports included in the analysis is limited. Additional head-to-head studies would be needed to re-evaluate clinical efficacy and safety of 5-ARI in combination or not with alpha blockers.

Purpose: To evaluate the detection rate of Magnetic Resonance Imaging/Transrectal Ultrasound (MRI/TRUS) Fusion Biopsy performed in a series of patients with suspicious prostate cancer in an ambulatory setting. Materials and methods: Between March 2018 and January 2019 a series of 155 patients undergoing MRI/TRUS fusionguided biopsy were prospectively enrolled. All patients presented a suspected diagnosis for prostate cancer because of raised Prostate Specific Antigen (PSA) serum level and/or abnormal physical examination (digital rectal examination), and showed at least one suspicious area at the multiparametric Magnetic Resonance Imaging (mpMRI). Results: Of 155 patients, 58 (37.4%) were biopsy-naïve, 97 (62.6%) had at least 1 previous negative TRUS-guided biopsy. The median age of the patient cohort was 66 years (IQR, 61- 69); the median prebiopsy PSA value was 7.1 ng/ml (IQR, 5- 8.9). Overall, the Fusion-TB findings were positive in 94 of 155 patients with a detection rate (DR) of 60%; a significantly high DR was obtained in terms of clinically significant prostate cancer (csPCa) by Fusion-TB (61 pts; 41.9%). The overall DR in the 121 biopsy-naive patients was 60.6%. In the subgroup of the 34 patients with at least 1 previous set of TRUS-GB, overall DR was 39.3% (35/50). Conclusions: The targeted MRI/TRUS fusion-guided biopsy represents a safe and accurate approach for diagnosis of csPCa, especially in patient with previous TRUS guided biopsy negative and suspicious prostate cancer.

Aim: The success of Robot Assisted Laparoscopic Prostatectomy (RALP) is mainly due to his relatively short learning curve. Twenty cases are needed to reach a “4 hours-proficiency”. However, to achieve optimal functional outcomes such as urinary continence and potency recovery may require more experience. We aim to report the perioperative and early functional outcomes of patients undergoing RALP, after a structured modular training program. Methods: A surgeon with no previous laparoscopic or robotic experience attained a 3 month modular training including: a) e-learning; b) assistance and training to the operating table; c) dry console training; d) step by step in vivo modular training performing 40 surgical steps in increasing difficulty, under the supervision of an experienced mentor. Demographics, intraoperative and postoperative functional outcomes were recorded after his first 120 procedures, considering four groups of 30 cases. Results: All procedures were completed successfully without conversion to open approach. Overall 19 (15%) post operative complications were observed and 84% were graded as minor (Clavien I-II). Overall operative time and console time gradually decreased during the learning curve, with statistical significance in favour of Group 4. The overall continence rate at 1 and 3 months was 74% and 87% respectively with a significant improvement in continence rate throughout the four groups (p = 0.04). Considering those patients submitted to nerve-sparing procedure we found a significant increase in potency recovery over the four groups (p = 0.04) with the higher potency recovery rate up to 80% in the last 30 cases. Conclusions: Optimal perioperative and functional outcomes have been attained since early phase of the learning curve after an intensive structured modular training and less than 100 consecutive procedures seem needed in order to achieve optimal urinary continence and erectile function recovery.

ABSTRACT Introduction and Objectives: We aim to present the use of 3D digital and physical renal model (1–5) to guide the percutaneous access during percutaneous nephrolithotripsy (PNL). Materials and Methods: We present the clinical case of a 30 years old man with left renal stone (25x15 mm). A virtual 3D reconstruction of the anatomical model including the stone, the renal parenchyma, the urinary collecting system (UCS) and the skeletal landmarks (lumbar spine and ribs) was elaborated. Finally, a physical 3D model was created with a 3D printer including the renal parenchyma, UCS and the stone. The surgeon evaluated the 3D virtual reconstruction and manipulated the printed model before surgery to improve the anatomical knowledge and to facilitate the percutaneous access. In prone position, combining ultrasound and fluoroscopy implemented by the preoperative anatomical planning based on the 3D virtual and printed model, an easy and safe access of the inferior calyx was achieved. Then, the patient underwent PNL using a 30 Fr Amplatz sheet with semi-rigid nephroscope and ultrasound energy to achieve a complete lithotripsy of the pelvic stone. Results: The procedure was safely completed with 1 single percutaneous puncture (time of puncture 2 minutes). Overall surgical time was 90 min. No intra and postoperative complications were reported. The CT scan performed before discharge confirmed a complete stone free state. Conclusion: The 3D-guided approach to PNL facilitates the preoperative planning of the puncture with better knowledge of the renal anatomy and may be helpful to reduce operative time and improve the learning curve.

Transperitoneal pyelolithotomy ,Retroperitoneal pyelolithotomy ,Diseases of the genitourinary system. Urology ,RC870-923 - Abstract
Objective: To compare the retroperitoneal with the transperitoneal approach in a series of patients underwent to robotic-assisted pyelolithotomy (RP). Materials and methods: From January 2015 to December 2018 we evaluated 20 patients subjected to robotic pyelolithotomy; 11 patients were treated with retroperitoneal approach (RRP) and 9 with transperitoneal approach (TRP). For each patient intra and perioperative data were recorded: operative time (OT), blood loss (BL), length of hospital stay (LOS), stone clearance, post-operative complications and time to remove the drain. The presence of stone fragments < 4 mm was considered as stone free rate. Results: The principal stone burden was greater in the TRP group than in the RRP group (48 ± 10 mm vs 32 ± 14 mm, p = 0.12). Preoperative hydronephrosis was present in 7 (64%) patients in RRP group and a mild hydronephrosis in 3 of TRP group (p = 0.04). The average operative time was higher in the RRP group than in the TRP group (203 ± 45 min vs 137 ± 31 min, p = 0.002). The average blood loss was 305 ± 175 ml in the RRP group versus 94 ± 104 ml in the TRP group (p = 0.005). The stone free rate was similar between the two groups, 36% (4 patients) in the RRP group and 44% (4 patients) in the TRP (p = 0.966). Conclusions: RP appears to be a safe and effective minimally invasive treatment for some patients with renal staghorn calculi or urinary tract malformations. The TRP may give lower operative time and better results in terms of blood loss and length of hospital stay.

Objectives: To evaluate the detection rate of prostate cancer (PCa) in patients who underwent to “in bore” Magnetic Resonance Imaging -guided prostate (MRI-GB) biopsy compared to the standard transrectal ultrasound guided prostate biopsy (TRUS-GB). Materials and methods: Between January 2017 and March 2015 a cohort of 39 consecutive patients was prospectively enrolled. All the patients underwent an "in-bore" guided MRI prostatic biopsy and subsequently ultrasound-guided standard prostate biopsy. Results: Median age of patients was 65.5 years (SD ± 6.6), median total PSA serum level was 6.6 ng/ml (SD ± 4.1), median prostate total volume was 51.1 cc (SD ± 26.7). Thirty of 39 (76.9%) were biopsy-naïve patients while 7/39 (17.9%) had at least one previous negative random TRUS-GB; 2/39 (5.1%) patients were already diagnosed as PCa and were on active surveillance. In 18/39 (53.8%) men Pca was diagnosed; as regards the MRI-GB results related to the PI-RADS score, biopsies of PIRADS 3 lesions were positive in 5/18 cases (27.8%), while the number of positive cases of PI-RADS 4 and 5 lesions was 7/11 (63.6%) and 6/10 (60%)respectively. At the histological examination, 4/39 (10.3%) had a PCa ISUP grade group 1, 11/39 (28.2%) had a ISUP 2, 6/39(15.4%) had a ISUP grade group 3 and 2/39 (5.1%) had a ISUP 4-5. Conclusions: MRI-GB represents a promising technique that may offer some of advantages compared to standard systematic TRUSGB. Our preliminary experience in MRI-GB resulted safe and feasible and represents a viable procedure for the diagnosis and characterization of PCa.

Objective: The aim of our study is to describe the use of posterior muscle-fascial reconstruction during urethro-ileal anastomosis in bladder cancer (BC) patients submitted to robot-assisted radical cystectomy (RC) with orthotopic neobladder (ON) and its role in facilitating day- and night-time continence recovery during a 12-month follow up. Materials and methods: We prospectively collected data from 42 consecutive patients who underwent RARC with totally intracorporeal ON and extended pelvic lymph node dissection (PLND) at our Institution from June 2014 to October 2017. Prior to the urethro-neobladder anastomosis we reconstructed the Denonvilliers Fascia (DF) as previously described for radical prostatectomy using a bidirectional barbed suture. Day and night-time recovery rates were reported at 3, 6 and 12 months after surgery, with continent patients being those using either no urinary pads or 1 safety pads. Results: Median age at surgery was 63 yrs, 41 (97.6%) patients were male. 28 (66.7%) patients presented a clinical T2 disease. Median operative time and median ON reconstruction time were 450 minutes and 180 minutes respectively. 13 (31%) individuals had non-organ confined disease, with 11 (26.2%) patients with positive lymph nodes (median 3 positive lymph nodes) and 2 (4.8%) with non-urothelial cancer at final pathologic examination. Median hospital stay and median catheterization time were 7 (IQR 7-8) and 21 (IQR 19-22). During first 30 post-operative days we recorded 7 (16.7%) low-grade Clavien and 2 (4.8%) IIIa Clavien complications, whereas between 30 and 90 postoperative days we recorded 4 (9.5%) low-grade, 4 (9.5) IIIa and 1 (2.4%) IIIb complications. Day-time and night-time continence rates were 61.9% vs 52.4%, 73.8% vs 64.3% and 90.5% vs 73.8% at three, six and twelve months follow up. Day-time continence was significantly superior in the younger group (97% vs 57%, p 0.01); night-time continence rates were also superior among < 70 yrs patients, despite not reaching statistical significance (77% vs 57%, p 0.3). Conclusions: Posterior muscle-fascial reconstruction aids continence recovery in BC patients undergoing RARC with ON, with younger and fitter patients most benefitting from ON reconstruction.

Pubic bone osteomyelitis is a rare infectious condition which is characterized by a complex diagnostic and therapeutic workup, due to its various clinical manifestations. Among the many causes of this condition, urinary fistula is the most common in case of previous urological procedures. In order to solve this complication, it is crucial to treat both the fistula and (moreover) the infectious locus arising from it, because treating the fistula alone does not provide any control on the infectious noxa. We present the first case of pubic bone osteomyelitis arising from a urinary fistula after a robotic radical cystectomy with intra corporeal continent neobladder, which has been successfully treated through a multidisciplinary approach.

The occurrence of kidney oncocytic lesions with an admixed papillary component is not unusual in routine pathology practice. These neoplasms with dual morphology are classically recognized as collision tumors with variable malignant potential. Using immunohistochemistry, we investigated fluorescent in situ hybridization and next generation sequencing of the genetic and phenotypic profiles in the two components of 11 kidney tumors with colliding oncocytic and papillary features. The oncocytic component was CD117 positive, CK7 negative, and AMACR negative; the papillary component was CK7 positive, AMACR positive, and CD117 negative in all cases. Fluorescence in situ hybridization (FISH) results were inconsistent. Next generation sequencing (NGS) analysis demonstrated that the mutations identified in the two tumor components were identical and displayed an allelic frequency of approximately 50%, strongly suspicious for genetic polymorphisms. The two oncocytic and papillary tumor counterparts shared the same genetic profile and did not harbor pathogenic mutations. Clinical confirmation of the biological benign features of these tumors is required. The term collision tumor is not suitable for these neoplasms, and we propose the term oncopapillary tumor for this histological entity.

Background: Clear cell tubulo-papillary renal cell carcinoma (cctpRCC) is characterized by clear cell morphology, but differs from conventional clear cell carcinoma (ccRCC) for its indolent clinical behavior and genetic background. The differential diagnosis between the two is based on histology and immunohistochemistry (IHC). Methods: We performed a comparative case-control histological, IHC, and genetic analysis by next generation sequencing (NGS), to point out the differences in 10 cases of cctpRCC, and six controls of ccRCC with low stage and grade. Results: All 16 cases showed the IHC profile with cytokeratin 7, racemase, and carbonic anhydrase IX expected for the histological features of each tumor type. By contrast, the NGS mutation analysis that covered 207 amplicons of 50 oncogenes or tumor suppressor genes provided conflicting results. Among the 10 cctpRCC cases, eight (80%) were wild type for all of the genes in the panel, while two (20%) harbored VHL mutations typical of ccRCC. Three of the six (50%) ccRCC control cases showed expected VHL mutations; two (33%) harbored pathogenic mutations in the p53 or the CKIT genes; and one (16%) was wild type. Conclusion: We can assume that histology and ICH are not sufficient for a definitive diagnosis of cctpRCC or ccRCC. Although with a panel covering 50 genes, we found that 80% of cctpRCC were genetically silent; thus, suggesting an indolent biology of these tumors. The differential diagnosis between ccptRCC and ccRCC for the choice of the best therapeutic strategy likely requires the comprehensive evaluation of histology, IHC, and at least VHL mutations.

In recent years, the development of diagnostic methods based on metabolic imaging has been aimed at improving diagnosis of prostate cancer (PCa) and perhaps at improving therapy. Molecular imaging methods can detect specific biological processes that are different when detected within cancer cells relative to those taking place in surrounding normal tissues. Many methods are sensitive to tissue metabolism, among them Positron Emission Tomography (PET) and Magnetic Resonance Spectroscopic Imaging (MRSI) which are widely used in clinical practice and clinical research. There is a rich literature that establishes the role of these metabolic imaging techniques as valid tools for the diagnosis, staging and monitoring of prostate cancer. Until recently, European guidelines for prostate cancer detection still considered both MRSI/MRI and PET/CT to be under evaluation, even though they had demonstrated their value in the staging of high risk prostate cancer, and in the restaging of patients presenting elevated PSA levels following radical treatment of PCa, respectively. Very recently, advanced methods for metabolic imaging have been proposed in the literature: mpMRI (multiparametric MRI), hyperpolarized MRSI, PET/CT with the use of new tracers and finally PET/MRI. Their detection capabilities are currently under evaluation, as is the feasibility of using such techniques in clinical studies.

Objective: We describe our technique for preservation of the smooth muscular internal (vesical) sphincter and proximal urethra during radical retropubic prostatectomy (RRP) and present our preliminary clinical results. Materials and methods: The first steps of the prostatectomy reflect the standard RRP, while for the final phases the procedure continues in an anterograde manner with incision of the fibers of the detrusor muscle at the insertion of the ventral surface of the base of the prostate. At this level, the inner circular muscle of the bladder neck forms a sphincteric ring of smooth muscle that covers the longitudinally oriented smooth muscle component of the urethral musculature that extends distally to the verumontanum. These two proximal structures represent the internal sphincter that envelops and locks the proximal urethra. A blunt dissection is continued until the ring shaped vesical sphincter is separated from the prostate and the longitudinally oriented smooth muscle component of the urethral musculature is identified. The base of the prostate is then gently separated from the urethra and from the bladder until the maximal length of the urethral musculature is isolated and preserved. Results: After 30 initial set-up procedures, 40 consecutive patients with organ confined prostate cancer were submitted to radical retropubic prostatectomy with the preservation of muscular internal sphincter and the proximal urethra and compared to 40 patients submitted to standard procedure who served as control group. The group of patients submitted to our technical modification had a faster recovery of early continence than control group at 3 and 7 days. Conclusions: The described technique is a feasible and safe method for preservation of the internal urethral sphincter and allows improving the early recovery of urinary continence. The technique does not increase the rate of positive margins and the duration of the procedure.

We report an interesting case of massive haematuria secondary to a rupture of a pseudoa- neurysm of the abdominal aorta below the renal vessels. A 65-year-old woman present- ed at our institution with a painful massive haematuria and anaemia. Two months before, she undergone a pelvic surgery complicated by an accidental injury of the right ureter sutured with a end-to-end anastomosis. An abdominal computed tomography (CT) scan with intravenous contrast showed a right-sided hydronephrosis with clots in the lumen of the right pelvis with a massive retroperitoneal hematoma due to a rupture of a iatrogenic pseudoaneurysm of the abdominal aorta below the origin of the renal arteries.
