Patients were randomized into two groups: group A (90 patients) underwent RIRS with a reusable flexible ureteroscope and group B (90 patients) were treated with a disposable one.Results: The patients’ demographics, stone features and pre-operative urine cultures were comparable between the groups. The Stone Free Rates (SFRs) were not significantly different (86.6% and 90.0% for group A and group B, respectively, p=0.11) and the mean cost for each procedure was comparable (2321 € in group A vs 2543 € in group B, p=0.09). However, the days of hospitalization and of antibiotic therapy were higher in group A (p ≤ 0.05). The overall complication rate in group A was 8.8% whilst in group B it was 3.3% (p ≤ 0.05); in particular, group A exhibited a greater number of major complications (Clavien score IIIa-V). The overall postoperative infection rate was 16.6% in group A and 3.3% in group B (p ≤ 0.05). Furthermore, none of the patients in group B developed urosepsis or had a positive blood culture, while 3 patients in group A did (p< 0.05).Conclusion: The use of disposable ureteroscopes is characterized by significantly lower post-operative complications and infection rates, while having comparable costs and SFRs vis à vis reusable ureteroscopes. Clinical Trial Registration Number: ISRCTN92289221.Keywords: RIRS, disposable ureteroscope, reusable ureteroscope, infection

Background: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations., Methods: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan)., Results: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis., Conclusions: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

Robotic surgery with Da Vinci has revolutionized the treatment of several diseases, including prostate cancer; nevertheless, costs remain the major drawback. Recently, new robotic platforms entered the market aiming to reduce costs and improve the access to robotic surgery. The aim of the study is to compare direct cost for initial hospital stay of radical prostatectomy performed with two different robotic systems, the Da Vinci and the new Hugo RAS system. This is a projection study that applies cost of robotic surgery, derived from a local tender, to the clinical course of robotic radical prostatectomy (RALP) performed with Da Vinci and Hugo RAS. The study was performed in a public referral center for robotic surgery equipped with both systems. The cost of robotic surgery from a local tender were considered and included rent, annual maintenance, and a per-procedure fee covering the setup of four robotic instruments. Those costs were applied to patients who underwent RALP with both systems since November 2022. The primary endpoint is to evaluate direct costs of initial hospital stay for Da Vinci and Hugo RAS, by considering equipment costs (as derived from the tender), and costs of theater and of hospitalization. The direct per-procedure cost is €2,246.31 for a Da Vinci procedure and €1995 for a Hugo RALP. In the local setting, Hugo RAS provides 11% of cost saving for RALP. By applying this per-procedure cost to our clinical data, the expenditure for the entire index hospitalization is € 6.7755,1 for Da Vinci and € 6.637,15 for Hugo RALP. The new Hugo RAS system is willing to reduce direct expenditures of robotic surgery for RALP; furthermore, it provides similar peri-operative outcomes compared to the Da Vinci. However, other drivers of costs should be taken into account, such as the duration of OR use-that is more than just console time and may depend on the facility's background and organization. Further variations in direct costs of robotic systems are related to caseload, local agreements and negotiations. Thus, cost comparison of new robotic platform still remains an ongoing issue., (© 2024. The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.)

Remote surgery provides opportunity for enhanced surgical capabilities, wider healthcare reach, and potentially improved patient outcomes. The network reliability is the foundation of successful implementation of telesurgery. It relies on a robust, high-speed communication network, with ultra-low latency. Significant lag has been shown to endanger precision and safety. Furthermore, the full-fledged adoption of telerobotics demands careful consideration of ethical challenges too. A deep insight into these issues has been investigated during the first Telesurgery Consensus Conference that took place in Orlando, Florida, USA, on the 3rd and 4th of February, 2024. During the Conference, the state of the art of remote surgery has been reported from robotic systems displaying telesurgery potential. The Hinotori, a robotic-assisted surgery platform developed by Medicaroid, experienced remote surgery as pre-clinical testing only; the Edge Medical Company, Shenzen, China, reported more than one hundred animal and 30 live human surgeries; the KanGuo reported human telesurgical cases performed with distances more than 3000 km; the Microport, China, collected more than 100 human operations at a distance up to 5000 km. Though, several issues-cybersecurity, data privacy, technical malfunctions - are yet to be addressed before a successful telesurgery implementation. Expanding the discussion to encompass ethical, financial, regulatory, and legal considerations is essential too. The Telesurgery collaborative community is working together to address and establish the best practices in the field., (© 2024. The Author(s).)

To evaluate the performance of a mathematical model to drive preoperative planning between RIRS and MiniPerc (MP) for the treatment of renal stones between 10 and 20 mm. Patients with a renal stone between 10 and 20 mm were enrolled. A mathematical model named Stone Management According to Size-Hardness (SMASH) score was calculated: hounsfield units (HU) χ stone maximum size (cm)/100. Patients were divided into 4 groups: RIRS with score < 15 (Group A), RIRS with score ≥ 15 (Group B), MP with score < 15 (Group C), MP with score ≥ 15 (Group D). Cyber Ho device was always used. Stone free rate (SFR) was assessed after 3 months. Complication rate and need for auxiliary procedures were evaluated. Between January 2019 and December 2021, 350 patients were enrolled (87, 88, 82 and 93 in Groups A, B, C and D). Mean stone size was 13.1 vs 13.3 mm in Group A vs B (p = 0.18) and 16.2 vs 18.1 mm in Group C vs D (p = 0.12). SFR was 82%, 61%, 75% and 85% for Groups A, B, C and D. SFR was comparable between Groups C and D (p = 0.32) and Groups A and C (p = 0.22). SFR was significantly higher in Group A over B (p = 0.03) and in Group D over B (p = 0.02). Complication rate was 2.2%, 3.4%, 12.1%, 12.9% for Groups A, B, C, D. RIRS and MP are both safe and effective. The mathematical model with the proposed cut-off allowed a proper allocation of patients between endoscopic and percutaneous approaches.Registration number of the study ISRCTN55546280., (© 2024.

We compared the perioperative outcomes of open (ORC) vs. robot-assisted (RARC) radical cystectomy in the treatment of pT4a MIBC. In total, 212 patients underwent ORC (102 patients, Group A) vs. RARC (110 patients, Group B) for pT4a bladder cancer. Patients were prospectively followed and retrospectively reviewed. We assessed operative time, estimated blood loss (EBL), intraoperative and postoperative complications, length of stay, transfusion rate, and oncological outcomes. Preoperative features were comparable. The mean operative time was 232.8 vs. 189.2 min ( p = 0.04), and mean EBL was 832.8 vs. 523.7 mL in Group A vs. B ( p = 0.04). An intraoperative transfusion was performed in 32 (31.4%) vs. 11 (10.0%) cases during ORC vs. RARC ( p = 0.03). The intraoperative complications rate was comparable. The mean length of stay was shorter after RARC (12.6 vs. 7.2 days, p = 0.02). Postoperative transfusions were performed in 36 (35.3%) vs. 13 (11.8%) cases ( p = 0.03), and postoperative complications occurred in 37 (36.3%) vs. 29 (26.4%) patients in Groups A vs. B ( p = 0.05). The positive surgical margin (PSM) rate was lower after RARC. No differences were recorded according to the oncological outcomes. ORC and RARC are feasible treatments for the management of pT4a bladder tumors. Minimally invasive surgery provides shorter operative time, bleeding, transfusion rate, postoperative complications, length of stay, and PSM rate.

Partial nephrectomy (PN) represents a procedure where the use of a robot has further enabled successful completion of this complex surgery. The results of this procedure using Versius Robotic Surgical System (VRSS) still need to be evaluated. Our working group described the technique and reported the initial results of a series of PN using VRSS. We presented our setting, surgical technique and outcomes for PN, using VRSS. Between 2022 and 2023, 15 patients underwent PN performed by two surgeons in two different centers. Fifteen patients underwent PN. The median lesion size identified on preoperative imaging was 4 (IQR 2.3-5) cm. Median PADUA score was 8 (IQR 7-9). Two procedures were converted to radical nephrectomy for enhanced oncological disease control. Of the 13 nephrectomies that were completed as partial, 7 were performed clampless and 6 with warm ischemia clamping. Median clamping time was 10 (IQR 9-11) minutes. No procedure was converted to open. Median blood loss was 200 (IQR 100-250) mL. Median total operative time was 105 (IQR 100-110) minutes. Median console time was 75 (IQR 66-80) minutes. Median set-up time was 13 (IQR 12-14) minutes. No intraoperative complications were reported. The median hospitalization time was 4 (IQR 3.5-4) days. None of the patients were transfused and none of the patients required readmission. In a pathology report, one patient had a positive surgical margin. Our initial experience suggests that performing PN using VRSS is feasible with good short-term outcomes., (© 2024.

Introduction: Versius CMR is a novel robotic system characterized by an open surgical console and independent bedside units. The system has potentials of flexibility and versatility, and has been used in urological, gynecological, and general surgical procedure. The aim is to depict a comprehensive analysis of the Versius system for pelvic surgery., Methods: This is a study involving two Institutions, ASST Santi Paolo and Carlo, Milan, and Apuane Hospital, Massa, Italy. All interventions performed in the pelvic area with the Versius were included. Data about indications, intra-, and post-operative course were prospectively collected and analyzed., Results: A total of 171 interventions were performed with the Versius. Forty-two of them involved pelvic procedures. Twenty-two had an oncological indication (localized prostate cancer), the remaining had a non-oncological or functional purpose. The mostly performed pelvic procedure was radical prostatectomy (22) followed by annexectomy (9). No intra-operative complication nor conversion to other approaches occurred. A Clavien II complication and one Clavien IIIb were reported. Malfunctioning/alarms requiring a power cycle of the system occurred in 2 different cases. An adjustment in trocar placement according to patients' height was required in 2 patients undergoing prostatectomy, in which the trocar was moved caudally. In two cases, a pelvic prolapse was repaired concomitant with other gynecological procedures., Conclusions: Pelvic surgery with the Versius is feasible without major complications; either dissection and reconstructive steps could be accomplished, provided a proper OR setup and trocar placement are pursued. Versius can be easily adopted by surgeons of different disciplines and backgrounds; a further multi-specialty implementation is presumed and long-term oncological and functional outcomes are awaited., (© 2024.

Objective: In the following years after the United States Preventive Service Task Force (USPSTF) recommendation against prostate cancer screening with PSA in 2012, several authors worldwide described an increase in higher grades and aggressive prostate tumors. In this scenario, we aim to evaluate the potential impacts of USPSTF recommendations on the functional and oncological outcomes in patients undergoing robotic-assisted radical prostatectomy (RARP) in a referral center., Material and Methods: We included 11396 patients who underwent RARP between 2008 and 2021. Each patient had at least a 12-month follow-up. The cohort was divided into two groups based on an inflection point in the outcomes at the end of 2012 and the beginning of 2013. The inflection point period was detected by Bayesian regression with multiple change points and regression with unknown breakpoints. We reported continuous variables as median and interquartile range (IQR) and categorical variables as absolute and relative percent frequencies., Results: Group 1 had 4760 patients, and Group 2 had 6636 patients, with a median follow-up of 109 and 38 months, respectively. In the final pathology, Group 2 had 9.5% increase in tumor volume, 24% increase on Gleason ≥ 4+3 (ISUP 3) , and 18% increase on ≥ pT3. This translated to a 6% increase in positive surgical margins and 24% reduction in full nerve sparing in response to the worsening pathology. There was a significant decline in post-operative outcomes in Group 2, including a 12-month continence reduction of 9%, reduction in potency by 27%, and reduction of trifecta by 22%., Conclusions: The increasing number of high-risk patients has led to worse functional and oncologic outcomes. The initial rapid rise in PSM was leveled by the move towards more partial nerve sparing. Among some historical changes in prostate cancer diagnosis and management in the period of our study, the USPSTF recommendation coincided with worse outcomes of prostate cancer treatment in a population who could benefit from PSA screening at the appropriate time., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Introduction: The optical trocar access (OTA) is a modified closed technique that aims to minimize the risk of vascular or bowel injuries while reducing the likelihood of gas leakage. A learning curve (LC) effect for OTA has been invoked with n = 30 procedures being considered as a threshold to define expertise. We aim to evaluate the impact of the LC within the first thirty cases of OTA performed by a trainee., Methods: This is a prospective randomized study on 60 patients elected to laparoscopic gynecological surgery. Patients were randomized to have OTA insertion by a junior surgeon or by an expert. LC was evaluated by: 1) insertion time; number of: 2) corrections by the senior; 3) times the tip of the trocar stopped in the preperitoneal layer; 4) mistakes of skin incision; 5) times the tip of the trocar ends under the omentum; 6) complications. To analyze the LC within the first 30 cases, procedures were stratified in 3 groups (cases 1-10; 11-20; 21-30) for both trainee and expert and LC variables were compared., Results: Overall, mean OTA insertion time was 56 s. No major intra- and post-operative complications were recorded. Mean insertion time was statistically significantly longer for the trainee compared to the expert within the first 10 cases (91 vs 33 s respectively, P = .01). For cases 11-20 and 21-30, time advantage of the senior surgeon is less evident (P = .05). The number of times the tip of the trocar stopped in the preperitoneal layer was similar between groups, as well as times the tip of the trocar ends under the omentum., Conclusions: OTA is a fast and simple way to achieve the pneumoperitoneum and first trocar insertion as a single step. The current series confirms the effectiveness of the technique since the beginning of the LC., (Copyright © 2023. Published by Elsevier España, S.L.U.)

The Hugo RAS and Versius are new robotic systems with a multimodular configuration, requiring a dedicated positioning of units, arms and trocars. While promising flexibility and multiquadrant opportunities-with an enhanced range of motion-the presence of multiple units around the patient should be effectively managed by the assistant and requires a new background of tasks. The article represents a practical guide while providing an overview on assistants' perspectives., (© 2023.

Robotic assisted radical cystectomy (RARC) is a standard option for the treatment of bladder cancer. Currently, novel platforms are entering the market and the Hugo RAS (Medtronic, Minneapolis, MN, USA) is a new system consisting of an open console with 3D-HD screen and a multi-modular fashion. Even if several series are already available for radical prostatectomy, to now a full description of RARC performed with Hugo RAS is still lacking. We report the first case of RARC with intracorporeal neobladder performed with the Hugo RAS-and another case of RARC with ureterostomy. Both patients were affected by MIBC. Case 1 was a 61-year-old patient without comorbidities (CCI 4), in which a Bordeaux ileal neobladder was scheduled after previous NAC. The second was the case of a 70-year-old one with CCI 7 and BMI 35; in this case, a ureterostomy was planned. Details of the robotic system: one 11 mm endoscope port was placed on the midline 2 cm above the umbilicus. Another two 8 mm robotic ports were symmetrically placed under vision on a transversal line-located 1 cm below the umbilicus. A third robotic port was positioned on the left side in a W configuration. All ports were located at least 9 cm between each other. Finally, two assistant ports were positioned in the right abdominal site. All arm-carts were parked 45-60 cm from the operative bed, before the docking process begins. Three arm-carts were parked on the left side, the assistant and the scrub nurse worked on the right side, while the energy tower stayed at the foot of the bed, according to the previous description of Hugo RAS robotic radical prostatectomy. The endoscope arm-cart is docked first, then the adjacent left carts are docked; finally, the surgeon's right-hand cart is docked from the right side of the bed. The docking angles and tilt we applied were: endoscope: 175°; minus 45°; surgeon left hand 140°; minus 30°; surgeon right hand 225°; minus 30°; fourth arm 125°; plus 15°. The instruments we used were those fitting our conventional four-instrument setup for RARC: monopolar shears, Maryland forceps, needle driver and Cadiere as the fourth arm. The procedures were completed without technical errors or technological failures-requiring a change in surgical strategy. Docking time was approximately 35 min; console time up to urethral dissection was 150 and 140 min in Case 1 and 2. The time for pelvic nodal dissection was approximately 37 min for both. The multi-modularity fashion of the Hugo RAS allowed an easy management of the bowel in Case 1; the absence of robotic staplers required the use of the laparoscopic ones, managed by an adjunctive assistant with room within the cart. In conclusion, RARC with the Hugo RAS is a feasible procedure able to reproduce all surgical steps without critical errors or complications requiring a change in surgical planning. Urinary diversion with intracorporeal reconstruction is feasible as well, with adequate preliminary outcomes., (© 2023.

Despite the arising interest in three-dimensional (3D) reconstruction models from 2D imaging, their diffusion and perception among urologists have been scarcely explored. The aim of the study is to report the results of an international survey investigating the use of such tools among urologists of different backgrounds and origins. Beyond demographics, the survey explored the degree to which 3D models are perceived to improve surgical outcomes, the procedures mostly making use of them, the settings in which those tools are mostly applied, the surgical steps benefiting from 3D reconstructions and future perspectives of improvement. One hundred responders fully completed the survey. All levels of expertise were allowed; more than half (53%) were first surgeons, and 59% had already completed their training. Their main application was partial nephrectomy (85%), followed by radical nephrectomy and radical prostatectomy. Three-dimensional models are mostly used for preoperative planning (75%), intraoperative consultation and tailoring. More than half recognized that 3D models may highly improve surgical outcomes. Despite their recognized usefulness, 77% of responders use 3D models in less than 25% of their major operations due to costs or the extra time taken to perform the reconstruction. Technical improvements and a higher availability of the 3D models will further increase their role in surgical and clinical daily practice.

The scenario of robotic surgery is rapidly evolving with the introduction of new robotic systems. A structured learning program in robotic surgery during academic education is often lacking, especially for undergraduates; as a result, many students may be unaware of indications to robotic surgery and technological progress. The aim of the study is to evaluate the knowledge and interest toward robotic surgery of medical and nurse students, and to analyze how the attractiveness may change after a hand-on training course with new simulators of Hugo RAS and Versius System. We performed a cross-sectional study involving medical and nurse students recruited on a voluntary basis at ASST Santi Paolo and Carlo, Milan; participants were invited to join a hands-on practice simulation with the Hugo RAS and/or Versius Trainer Simulator. Before the hand-on exercise, students were asked to fulfill an online anonymous questionnaire addressing knowledge and interest toward robotic surgery. After a 2-h hands-on exercises at the Hugo RAS and/or at the Versius Trainer simulator (preceded by a brief lecture on robotic surgery and new systems), participants were asked to complete a second-round questionnaire to evaluate changes in attractiveness toward robotic surgery. Data were recorded in a database; after a descriptive analysis of the variables, median values were compared with the Mann-Whitney U test, frequencies with the Fisher's exact test and in the case of paired observations (before and after the simulation), the Mc Nemar test was used. Forty-one undergraduates agreed to participate. Twenty-three nursing students and 18 medical students were recruited. Some of them had a basic knowledge in robotic surgery and were able to figure out some surgical indications, given the presence of a robotic program already settled up at the institution. Before the hands-on course, 44.0% nurse students and 36.6% of medical students were interested in surgical disciplines and robotic surgery. After the simulation, all students (100%) reported a high level of interest in robotic surgery and some of them required for a dedicated internship (p < 0.001). The students provided also feedback on the perceived ease-of-use of the robotic simulators (on a scale 0-10); overall, the median score was 8, IQR [7-8], with no differences between nursing and medical students (p = 0.482). In conclusion, the study demonstrates a great interest toward robotic surgery as a part of medical and nurse education. A hands-on simulation further improved the interest of undergraduates from both backgrounds. The technological progress with the availability of new surgical systems will be the future challenge of training programs and should be considered at all levels of education., (© 2023.

Objective: To compare intra and early postoperative outcomes between pulsed-wave and continuous-wave Thulium Fiber Laser Enucleation of the Prostate (PW-ThuFLEP vs CW-ThuFLEP) for the treatment of benign prostatic hyperplasia., Methods: 238 patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent PW-ThuFLEP (118 patients) vs CW-ThuFLEP (120 patients). Preoperative prostate volume, adenoma volume, prostate-specific antigen (PSA), and hemoglobin values were recorded. International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual volume, and International Index of Erectile Function-5 score (IIEF-5) were assessed. Operative time, enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin drop, and postoperative complications were recorded. Micturition improvements and sexual outcomes were evaluated 3months after surgery., Results: CW-ThuFLEP showed shorter operative time (61.5 vs 67.4 minutes, P = .04). Enucleation time (50.2 vs 53.3 minutes, P = .12), enucleation efficiency (0.8 vs 0.7 g/min, P = .38), catheterization time (2.2 vs 2.1days, P = .29), irrigation volume (32.9 vs 32.8L, P = .71), hospital stay (2.8 vs 2.6days, P = .29) and hemoglobin drop (0.38 vs 0.39 g/dL, P = .53) were comparable. No significant difference in complication rate was observed. At 3-month follow-up, the procedures did not show any significant difference in IPSS, Qmax, post-void residual volume, IIEF-5, and PSA value., Conclusion: PW-ThuFLEP and CW-ThuFLEP both relieve lower urinary tract symptoms equally, with high efficacy and safety. Operative time was significantly shorter with CW-ThuFLEP, but with a small difference with low clinical impact. Enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin and PSA drop, complication rate, and sexual outcomes showed no differences., Competing Interests: DECLARATION OF COMPETING INTEREST None., (Copyright © 2023 Elsevier Inc.

Background: Robot-assisted surgery ensures minimal invasiveness; since the expiry of the Da Vinci patent, new robotic systems have entered the market. Recently, the Hugo RAS received CE approval for several surgical procedures. However, more is needed to know about skill acquisition at the new simulator., Objective: This study aims to analyse the factors impacting basic surgical skills at the Hugo RAS simulator., Design Setting and Participants: We present a cross-sectional study involving 71 participants of different backgrounds invited to a hands-on session with the Hugo RAS simulator voluntarily. All of them had no prior expertise with the system. Participants were recruited among medical/nurse students, residents, and laparoscopic and robotic surgeons., Intervention: All participants underwent a hands-on "pick and place" exercise at the Hugo RAS simulator; the metrics of a second-round pick and place exercise were recorded., Outcome Measurements and Statistical Analysis: Metrics were analysed with regard to the following variables: demographics, videogame use, and prior surgical experience (no surgical expertise, experience with laparoscopy, and experience with robotic console)., Results and Limitations: All participants completed the test. Of them, 77.5% were naïve to surgery, 8.5% had prior laparoscopic expertise, and 14.1% had prior robotic console experience. The time to complete the pick and place exercise was significantly lower ( p  < 0.001) among prior robotic surgeons (38 s, interquartile range [IQR] 34-45) compared with both naïve participants (61 s, IQR 53-71) and laparoscopists (93 s, IQR 53-162). The overall score of the exercise decreased with age ( p  = 0.046); however, the overall scores were significantly and steadily higher among surgeons experienced in robotic consoles across all age groups ( p  = 0.006). Neither gender ( p  = 0.7) nor videogame use ( p  = 0.9) correlated significantly with the metrics., Conclusions: This is the first study analysing factors impacting basic skill acquisition at a new robotic simulator. Experience with robotic consoles may represent a major factor, raising the hypothesis of the transferability of basic robotic skills across different robotic systems. Further studies are required to explore this issue., Patient Summary: In the present study, we analysed which characteristics may affect the basic surgical skills at a novel robotic platform., (© 2023 The Authors.)

(1) Background: While females start their gynecological examinations during puberty, only few men decide to be visited by urologists in their youth. Given the participation in the EcoFoodFertility research project, our department had the opportunity to screen young males that were supposedly healthy. (2) Results: from January 2019 to July 2020, we evaluated 157 patients with sperm, blood analysis, and uroandrological examinations. The inclusion criteria were age 18-40 and absence of previous urological disease (urology-naïve). The primary endpoint of the study was to record uroandrological diseases that are occasionally discovered during examination in asymptomatic young men. The average age was 26.9 years (range 18-40); average testicular volume was 15.7 mL (range 12-22 mL); and 45.2% reported abnormal semen analysis: 62 cases of teratozoospermia, 27 asthenozoospermia, 18 oligozoospermia, and 2 azoospermia were discovered respectively; 4/157 patients were diagnosed with hypogonadism; 2 cases with suspicious testicular mass resulted in testicular cancer; and 31 suspected varicoceles and 8 patients with mild sexual dysfunctions were managed. (3) Conclusions: an uroandrological evaluation of young asymptomatic males allowed for the prompt diagnosis of different urological conditions, including cancerous ones, in our series. Despite being debatable, combining urological counselling with physical examination, semen analysis, and a laboratory profile could be useful and cost-effective in order to ameliorate male health.

Background: Vapor Tunnel (VT) technology is the result of a pulse modulation during holmium laser emission which reduces stone retropulsion. We present the outcomes of this tool in the treatment of ureteral stones., Methods: Two hundred ten patients with a ureteral stone were randomly assigned to holmium laser lithotripsy with (group A) or without (group B) the VT technology. The 35 W LithoEVO laser generator (Quanta System, Samarate, Varese, Italy) was used. We compared operative time, dusting time, delivered energy, retreatment rate due to stone push-up, ureteral lesions, and stone-free rate (SFR) and postoperative strictures at 1 month. We also compared outcomes according to stone position., Results: VT technology was associated with significantly lower mean operative time (25.7 vs. 37.2 min), dusting time (9.7 vs. 15.3 min), delivered energy (7.7 vs. 19.9 KJ). In group B 9 patients (8.5%) were retreated due to stone push-up (P=0.01) for a proximal or middle stone, 6 (5.7%) postoperative strictures occurred (P=0.03) and a higher ureteral lesion rate was observed (7.6% vs 35.2%, P=0.04). 1-month SFR was comparable (93.4% vs. 88.6%, P=0.11). Postoperative complication rate was higher in group B (P=0.05). Without VT technology, ureteral lesions and strictures rates were significantly higher independently from stone position., Conclusions: The VT technology is associated with significantly lower operative and dusting time independently from stone position, due to a reduced retropulsion, which makes treatment quicker and easier. It also avoids stone push-up especially for proximal and middle stones and reduces ureteral lesions, postoperative complications, and ureteral strictures.

Background: Neuromodulation (NM) is a family of therapies based on electrical stimulation to target specific nerves that control LUTS (Lower Urinary Tract Symptoms) and pain. The aim is to modulate what is happening within the nervous system to achieve therapeutic effects. A particular type of neuromodulation, called TENS (Transcutaneous Electrical Nerve Stimulation), has proven effective for treating pelvic pain. The available evidence provides indications regarding the many aspects of TENS that influence therapeutic effects, but a comprehensive review has yet to be conducted., Methods: Scoping review on Pubmed, CINAHL, Embase, Scopus, and Web of Science, including clinical trials, reviews, case studies or series, and other descriptive studies, according to the Joanna Briggs and PRISMA methodology., Results: The 31 papers retrieved allowed the formulation of precise indications about the DOs and DON'Ts of electrode placement, waveform, pulse duration, pulse frequency, amplitude, session duration, and frequency of sessions. This paper also discusses the biochemical and neuro urological mechanisms of TENS., Conclusion: TENS effectiveness is influenced by many factors, some self-evident, others subtle, which this paper elucidates. Pelvic pain requires a multimodal approach, of which TENS is just a part. TENS should therefore be viewed as one of the components of the rehabilitation program in the frame of thorough and continuous patient assessment., (© 2023 The Authors.

Radical cystectomy represents one of the most challenging surgical procedures, exhibiting a high morbidity rate. The transition to minimally invasive surgery in the field has been steep, due to either the technical complexity and prior concerns of atypical recurrences and/or peritoneal spread. More recently, a larger series of RCTs has proven the oncological safety of robot-assisted radical cystectomy (RARC). Beyond survival outcomes, the comparison between RARC and open surgery in terms of peri-operative morbidity is still ongoing. We present a single-center experience of RARC with intracorporeal urinary diversion. Overall, 50% of patients had an intracorporeal neobladder reconstruction. The series confirms a low rate of complications (Clavien Dindo ≥ IIIa 7.5%) and wound infections (2.5%) and the absence of thromboembolic events. No atypical recurrences were found. To discuss these outcomes, we reviewed the literature related to RARC including level-1 evidence. PubMed and Web of Science searches were performed using the medical subject terms "robotic radical cystectomy" and "randomized controlled trial (RCT)". Six unique RCTs comparing robot and open surgery were found. Two clinical trials dealt with RARC with an intracorporeal reconstruction of UD. Pertinent clinical outcomes are summarized and discussed. In conclusion, RARC is a complex but feasible procedure. The transition from extracorporeal urinary diversion (UD) to a complete intracorporeal reconstruction could be the key to improving peri-operative outcomes and reducing the whole morbidity of the procedure.

Introduction: Ex-vivo FCM is a novel digital optical technique that provides images of fresh tissues in a real-time fashion with magnification to subcellular details of a flattened unprocessed sample. Digital images are hematoxylin-eosin-like and can be shared and interpreted remotely. In urology, FCM has been successfully applied for prostate tissue interpretation, either during biopsy and radical prostatectomy. Possible applications of FCM may reflect those of frozen section analysis and can be extended to all fields in which the intra-operative microscopical control is advisable., Materials and Methods: This is an investigative prospective case series that aims to explore FCM feasibility in novel surgical settings and provide a depiction of FCM digital images in those fields. The definite purpose is to check the accuracy of surgical specimen during the following interventions: (a) trans-urethral resection of bladder tumors, to confirm the presence of muscular layer; (b) biopsy of a retroperitoneal mass, to check for the location and quality of cores; (c) training in robotic radical prostatectomy, to control surgical margins after a nerve sparing performed by a trainee. To this aim, we collected FCM images during seven surgical procedures. FCM findings were compared to those from the final histopathological analysis and the agreement was assessed., Results: In all cases, FCM digital images were obtained in the OR. FCM was able to confirm the presence of muscular layer in TURB specimen, the presence of lymphomatous tissue, surgical margins at prostate specimen. FCM intra-operative interpretation was consistent with final histopathology in all cases., Conclusions: Ex vivo FCM may represent a novel approach to control the quality of specimens, likely to tailor surgical strategy in a real-time fashion. Moreover, digitalization represents a step toward the implementation of telepathology in clinical practice.

Introduction: The PRECE is a model predicting the risk of extracapsular extension (ECE) of prostate cancer: it has been developed on more than 6000 patients who underwent robotic radical prostatectomy (RARP) at the Global Robotic Institute, FL, USA. Up to now, it is the single tool predicting either the side and the amount of ECE. The model has a free user-friendly interface and is made up from simple and available covariates, namely age, PSA, cT, GS and percent of positive core, the latter topographically distributed within the prostate gland. Despite the successful performance at internal validation, the model is still lacking an external validation (EV). The aim of the paper is to externally validate the PRECE model on an Italian cohort of patients elected to RARP., Methods: 269 prostatic lobes from 141 patients represented the validation dataset. The EV was performed with the receiver operating characteristics (ROC) curves and calibration, to address the ability of PRECE to discriminate between patients with or without ECE., Results: Overall, an ECE was found in 91 out of the 269 prostatic lobes (34%). Twenty-five patients out of pT3 had a bilateral ECE. The ROC curve showed an AUC of 0.80 (95% CI 0.74-0.85). Sensitivity and specificity were 77% and 69%, respectively. The model showed an acceptable calibration with tendency towards overestimation., Conclusions: From the current EV, the PRECE displays a good predictive performance to discriminate between cases with and without ECE; despite preliminary, outcomes may support the generalizability of the model in dataset other than the development one., (© 2022.

Purpose: To compare endoscopic enucleation of the prostate using a thulium: yttrium-aluminum-garnet (Tm:YAG) laser and a super-pulsed thulium fiber laser set in continuous-wave (CW) mode, and to evaluate whether theoretical advantages of thulium fiber lasers, related to their shorter wavelength, translate into relevant clinical differences., Methods: In total, 110 patients suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia were randomized to undergo either thulium:YAG laser enucleation of the prostate (ThuLEP) or CW thulium fiber laser enucleation of the prostate (CW-ThuFLEP). Intraoperative and postoperative variables and complications were compared. Micturition improvement was assessed at 3-month follow-up using the International Prostate Symptom Score (IPSS), post-void residual urine (PVR) and maximum flow rate (Qmax). Erectile function was evaluated using the International Index of Erectile Function-5 (IIEF-5)., Results: No significant differences between the ThuLEP and CW-ThuFLEP groups were found in terms of operative time (70.69 vs 72.41 min), enucleation time (50.23 vs 53.33 min), enucleated tissue weight (40.2 vs 41.9 g), enucleation efficiency (0.80 vs 0.79 g/min), catheterization time (2.45 vs 2.57 days), hospital stay (2.82 vs 2.95 days) and hemoglobin drop (1.05 vs 1.27 g/dl). At 3-month follow-up, no significant differences were found in IPSS (5.09 vs 5.81), Qmax (26.51 vs 27.13 ml/s), PVR (25.22 vs 23.81 ml) and IIEF-5 (14.01 vs 14.54)., Conclusion: ThuLEP and CW-ThuFLEP were equivalent in relieving patients from LUTS and improving micturition. Theoretical advantages of the TFL, such as shallower penetration depth and improved vaporization capacity, did not translate into relevant perioperative outcomes or clinical differences., (© 2022.

The occurrence of asymptomatic bacteriuria concomitant to urolithiasis is an issue for patients undergoing renal stone treatment. Disposing of a preoperative urine culture is essential to reduce the risk of septic events. The endpoint of the study is to report which characteristics of candidates for renal stone treatment are frequently associated with positive urine culture. 2605 patients were retrospectively enrolled from 14 centers; inclusion criteria were age > 18 and presence of a single renal stone 1-2 cm in size. The variables collected included age, gender, previous renal surgery, comorbidities, skin-to-stone distance, stone size, location, density, presence of hydronephrosis. After a descriptive analysis, the association between continuous and categorical variables and the presence of positive urine culture was assessed using a logistic regression model. Overall, 240/2605 patients (9%) had preoperative bacteriuria. Positive urine culture was more frequent in females, patients with previous renal interventions, chronic kidney disease, congenital anomalies, larger stones, increased density. Multivariate analysis demonstrated that previous renal interventions (OR 2.6; 95% CI 1.9-3.4; p < 0.001), renal-related comorbidities (OR 1.31; 95% CI 1.19-1.4; p < 0.001), higher stone size (OR 1.06; 95% CI 1.02-1.1; p = 0.01) and density (OR 1.00; 95% CI 1.0-1.00; p = 0.02) were associated with bacteriuria; male gender and lower caliceal location were inversely related to it. Beyond expected risk factors, such as female gender, other parameters are seemingly favoring the presence of positive urine culture. The awareness of variables associated with bacteriuria allows to assess which individuals are at increased risk of presenting bacteriuria and reduce the rate of septic complications., (© 2022.

Prostate cancer and bladder cancer accounts for approximately 13.5% and 3% of all male cancers and all newly diagnosed cancers (regardless sex), respectively. Thus, these cancers represent a major health and economic burden globally. The knowledge of lymph node status is an integral part of the management of any solid tumor. In the urological field, pelvic lymph node dissection (PLND) is of paramount importance in the diagnosis, management, and prognosis of prostate and bladder cancers. However, PLND may be associated with several comorbidities. In this narrative review, the most recent updates concerning the patterns and incidence of lymph node metastasis, the role of different imaging studies and nomograms in determining patients' eligibility for PLND, and the anatomical templates of PLND in urologic patients with bladder or prostate cancer will be discussed.

Purpose: We performed a prospective randomized comparison among Retrograde IntraRenal Surgery (RIRS) and MiniPerc (MP) for stones between 10 and 20 mm to evaluate outcomes with the same laser device: Fiber Dust., Methods: Patients with a single renal stone between 10 and 20 mm were randomized to RIRS (Group A) versus MP (Group B). Exclusion criteria were age < 18 or > 75, presence of acute infection, coagulation impairments, cardiovascular or pulmonary comorbidities. In both groups, the Fiber Dust laser was used. A CT scan after 3 months was performed. A negative CT scan or asymptomatic patients with stone fragments < 3 mm and a negative urinary culture were the criteria to assess the stone-free status. A statistical analysis was carried out to assess success, complication and retreatment rates and need for auxiliary treatments., Results: Between January 2021 and January 2022, 186 patients were enrolled (90 in Group A and 96 in Group B). Mean stone size was 15.8 mm and 14.9 mm in Group A and B, respectively (p = 0.23). The overall stone-free rate (SFR) was 73.3% for Group A and 84.4% for Group B. A higher SFR was reached for upper calyceal stones in Group A (90.4%) lower calyceal stones in Group B (91.6%). Retreatment rate (p = 0.31) and auxiliary procedure rate (p = 0.18) were comparable. Complication rate was 5.5% and 5.2% for Groups A and B, respectively., Conclusions: RIRS and MP are both effective to obtain a postoperative SFR with Fiber Dust. According to the stone position one treatment is superior to the other one., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Introduction: Active surveillance (AS) is a treatment strategy for low-risk prostate cancer (PCa) patients, with extended indication to some intermediate-risk PCa. However, active treatment is necessary in case of disease progression and robotic radical prostatectomy (RALP) is one of the treatment modalities. The aim of the study is to compare outcomes of a delayed RALP after an initial heterogeneous surveillance strategy with those of immediate RALP in a single referral center. Methods: Data from patients who underwent RALP after initial assumed "active surveillance" (referred from different institutions and backgrounds) were compared to those of patients who underwent an immediate RALP after propensity score (PS) matching. The PS analysis was performed matching ISUP score at the time of entering surveillance with ISUP at RALP for the control group; other matching covariates at the time of surgery were considered (including age, prostate-specific antigen, body mass index, prostate size, cT, pre-op Sexual Health Inventory for Men, etc.). Perioperative, functional, and oncological outcomes were compared between groups. Results: Three hundred sixty-two RALP patients were included (181 after surveillance and 181 immediate RALP). Patients after surveillance had a worse pT and ISUP score ( p  < 0.001); LVI and EPE were higher in the surveilled group (13% vs. 5%, p  = 0.001; 38% vs. 22%, p  = 0.001), without significant difference in positive surgical margin. At a median follow-up of 24 months, the risk of biochemical recurrence (BCR) was significantly higher for delayed RALP (hazard ratio: 4.0; 95% confidence interval: 1.4-12; p  = 0.013), whereas potency and continence rate did not differ significantly. Conclusions: At a referral center receiving patients from diverse backgrounds, outcomes of RALP after heterogeneous surveillance strategies are variable and less predictable, maybe attributable to different protocols and surgical planning. The higher BCR rate in a high-risk surveilled cohort may suggest an increased burden of cancer-related care for RALP patients after surveillance.

Rectal perforations during pelvic surgery are rare but serious complications. The occurrence of rectal involvement is generally lower than that of the involvement of other portions of the bowel. The urologic field is responsible for the majority of iatrogenic rectal injuries from pelvic surgery; general and gynecologic surgeries are prone to the occurrence as well, the latter especially in the case of rectal shaving for deep infiltrating endometriosis. Attention should be posed to the prevention of rectal injuries, especially in case of challenging or salvage procedures; some tricks may be recommended to avoid thermal and mechanical damages and to realize a safe dissection. Intraoperative detection of rectal injuries is of paramount importance; once confirmed, immediate management with the closure of the defect is recommended. In general, rectal injuries diagnosed after surgery are liable to significantly worse outcomes than those detected and managed intraoperatively., Patient Summary: Rectal perforation is a rare but possible complication of pelvic surgeries. The more challenging the procedure (ie, surgery for locally advanced tumors or after radiation therapy), the higher the risk of rectal lesion. Intraoperative management of the injury should be attempted, with direct repair of the defect with or without fecal diversion., (© 2022 The Author(s).)

Background: Prostate cancer is the most commonly diagnosed neoplasm in men. From the introduction of PSA testing, an increasing number of men undergoes prostate biopsy (PBX). While the physical side effects of PBx have been well investigated, its psychological impact has been under-evaluated., Aim: The aim of our study is to investigate the presence of psychological distress (anxiety and depression) in patients waiting for histopathological results after prostate biopsy (PBx)., Methods: From February to April 2019, 51 consecutive patients undergoing prostate biopsies at our institution were included. Age, PSA, DRE, familiarity for prostate cancer, number of previous biopsies, type of anesthesia, number of cores were recorded. All patients filled the Hospital Anxiety and Depression Scale (HADS), a psychometric Likert-scale questionnaire, before receiving the histopathological results of their PBx., Results: The prevalence of psychological distress among patients awaiting histopathologic results is 41% (21/51 patients), with anxiety being the main component of their distress. On multivariate analysis, PSA, family history, and repeat biopsy were significantly associated with anxiety and depression., Conclusion: Patients undergoing PBx experience a burden of psychological distress waiting for histopathologic results, especially anxiety. Appropriate counseling should be offered to patients at high risk of developing psychological distress after PBx. Future goals would include technological improvements to shorten the time between biopsy and definitive results.

Context: Erectile dysfunction (ED) following radical prostatectomy is a concern for patients and their partners. Low-intensity extracorporeal shockwave therapy (LI-ESWT) can potentially enhance tissue repair and regeneration. The aim of the current study was to systematically review the literature to assess the role of LI-ESWT in the management of patients with postprostatectomy ED., Evidence Acquisition: Two authors independently performed a systematic search of the PubMed and Web of Science databases to identify all relevant articles. Non-English reports, case reports, reviews, letters, and editorials were excluded. Risk of bias was assessed according to the GRADE guidelines., Evidence Synthesis: Nine articles met the inclusion criteria and were included in the qualitative analysis. All the studies included were published between 2015 and 2022 and the majority of them compared phosphodiesterase type 5 inhibitors (PDE5Is) alone versus a combination of LI-ESWT and PDE5Is. Only three studies were randomized controlled trials (RCTs). In general, there is no standardized protocol for LI-ESWT for postprostatectomy ED. In comparisons of LI-ESWT + PDE5Is versus PDE5Is alone, some authors found a statistically significant improvement in erectile function with LI-ESWT + PDE5Is. The starting time for LI-ESWT differed among the studies, ranging from 3 d to 6 mo after surgery. The main limitations of the review are the scarcity of studies, small sample sizes, high risk of bias, and high heterogeneity among studies., Conclusions: There is currently limited evidence on the use of LI-ESWT either alone or in combination with PDE5Is in penile rehabilitation protocols after prostatectomy. However, small clinical trials with short follow-up show that LI-ESWT could potentially play a role in the management of postprostatectomy ED in the future. Further RCTs with larger sample sizes are needed., Patient Summary: Despite limited reports in the literature, low-intensity shockwave therapy after removal of the prostate is a promising noninvasive treatment for dealing with erectile dysfunction after surgery., (© 2022 The Authors.)
