RESUMO
OBJECTIVE: To provide the first clinical validation of the European Association of Urology Robotic Urology Section (ERUS) curriculum for training in robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC). PATIENTS AND METHODS: The ERUS proposed a structured curriculum, divided into 11 steps, to train novice surgeons and help overcome the steep learning curve associated with iRARC. In this study, one trainee completed the curriculum under the mentorship of an expert. Twenty-one patients were operated on by the trainee following the proposed iRARC curriculum [(t)iRARC group] and were compared with 42 patients treated with the standard of care by the mentor [(m)iRARC group]. To evaluate curriculum safety, peri-operative outcomes, surgical margins and complications were assessed. Propensity-score matching (1:2) was used to identify comparable (t)iRARC and (m)iRARC cases. Matched variables included age, body mass index, neoadjuvant therapy, American Society of Anesthesiologists score and cT stage. Mann-Whitney and chi-squared tests were used to compare peri- and postoperative outcomes between the two cohorts. To evaluate curriculum efficacy, steps attempted and completed by the trainee were assessed and studied as a function of growing surgical experience of the trainee. RESULTS: The trainee progressed in proficiency-based training through steps of increasing difficulty. No differences in estimated blood loss, positive soft tissue margins, number of resected lymph nodes, overall and high-grade complications, or 90-day readmissions between the (t)iRARC and (m)iRARC groups were observed (all P > 0.05). However, operating time was significantly longer in the (t)iRARC group (P = 0.01). Of the 209 available steps, the trainee attempted 168 (80%) and successfully performed 125 (60%). Increasing experience was associated with more steps being successfully performed (P < 0.001). CONCLUSIONS: The proposed ERUS curriculum assists naïve surgeons during the learning curve for iRARC and should be encouraged in order to guarantee optimal outcomes during the learning phase of this procedure.

PURPOSE: In the emerging field of robotics, only few studies investigated the transition between different robotic platforms in terms of surgical outcomes. We aimed at assessing surgical outcomes of patients receiving robot-assisted radical prostatectomy (RARP) and robot-assisted partial nephrectomy (RAPN) at a high-volume robotic center during the transition from Si to Xi Da Vinci surgical systems. METHODS: We analyzed data of 1884 patients undergoing RARP (n = 1437, 76%) and RAPN (n = 447, 24%) at OLV hospital (Aalst, Belgium) between 2011 and 2021. For both procedures, we assessed operative time, estimated blood loss, length of stay, and positive surgical margins. For RARP, we investigated length of catheterization and PSA persistence after surgery, whereas warm ischemia time, clampless surgery, and acute kidney injury (AKI) were assessed for RAPN. Multivariable analyses (MVA) investigated the association between robotic platform (Si vs. Xi) and surgical outcomes after adjustment for patient- and tumor-related factors. RESULTS: A total of 975 (68%) and 462 (32%) patients underwent RARP performed with the Si vs. Xi surgical system, respectively. Baseline characteristics did not differ between the groups. On MVA, we did not find evidence of a difference between the groups with respect to operative time (estimate: 1.07) or estimated blood loss (estimate: 32.39; both p > 0.05). Median (interquartile range [IQR]) length of stay was 6 (3, 6) and 4 (3, 5) days in the Si vs. Xi group, respectively (p < 0.0001). On MVA, men treated with the Xi vs. Si robot had lower odds of PSM (Odds ratio [OR]: 0.58; p = 0.014). A total of 184 (41%) and 263 (59%) patients received RAPN with the Si and Xi robotic system, respectively. Baseline characteristics, including demographics, functional data, and tumor-related features did not differ between the groups. On MVA, operative time was longer in the Xi vs. Si group (estimate: 30.54; p = 0.006). Patients treated with the Xi vs. Si system had higher probability of undergoing a clampless procedure (OR: 2.56; p = 0.001), whereas the risk of AKI did not differ between the groups (OR: 1.25; p = 0.4). On MVA, patients operated with the Xi robot had shorter length of stay as compared to the Si group (estimate: - 0.86; p = 0.003), whereas we did not find evidence of an association between robotic system and PSM (OR: 1.55; p = 0.3). CONCLUSION: We found that the Xi robot allowed for improvements in peri-operative outcomes as compared to the Si platform, with lower rate of positive margins for RARP and higher rate of off-clamp procedures for RAPN. Hospital stay was also shorter for patients operated with the Xi vs. Si robot, especially after robot-assisted partial nephrectomy. Awaiting future investigations-in particular, cost analyses-these results have important implications for patients, surgeons, and healthcare policymakers.

INTRODUCTION: Bladder neck dissection is one of the most delicate surgical steps of robotic-assisted radical prostatectomy (RARP) [1, 2], and it may affect surgical margins rate and functional outcomes [3, 4]. Given the relationship between outcomes and surgical experience [5-7], it is crucial to implement a step-by-step approach for each surgical step of the procedure, especially in the most challenging part of the intervention. In this video compilation, we described the techniques for bladder neck dissection utilized at OLV Hospital (Aalst, Belgium). SURGICAL TECHNIQUE: We illustrated five different techniques for bladder neck dissection during RARP. The anterior technique tackles the bladder neck from above until the urethral catheter is visualized, and then the dissection is completed posteriorly. The lateral and postero-lateral approaches involve the identification of a weakness point at the prostate-vesical junction and aim to develop the posterior plane - virtually until the seminal vesicles - prior to the opening of the urethra anteriorly. Finally, we described our techniques for bladder neck dissection in more challenging cases such as in patients with bulky middle lobes and prior surgery for benign prostatic hyperplasia. All approaches follow anatomic landmarks to minimize positive surgical margins and aim to preserve the bladder neck in order to promote optimal functional recovery. All procedures were performed with DaVinci robotic platforms using a 3-instruments configuration (scissors, fenestrated bipolar, and needle driver). As standard protocol at our Institution, urinary catheter was removed on postoperative day two [8]. CONCLUSIONS: Five different approaches for bladder neck dissection during RARP were described in this video compilation. We believe that the technical details provided here might be of help for clinicians who are starting their practice with this surgical intervention.

INTRODUCTION: The optimal management of the urethra in patients planned for radical cystectomy (RC) remains unclear. We sought to evaluate the impact of urethrectomy on perioperative and oncological outcomes in patients treated with RC for non-metastatic urothelial carcinoma of the bladder (UCB). MATERIALS AND METHODS: We assessed the retrospective data from patients treated with RC for UCB of five European University Hospitals. Associations of urethrectomy with progression-free (PFS), cancer-free (CSS), and overall (OS) survivals were assessed in univariable and multivariable Cox regression models. We performed a subgroup analysis in patients at high risk for urethral recurrence (UR) (urethral invasion and/or bladder neck invasion and/or multifocality and/or prostatic urethra involvement). RESULTS: A total of 887 non-metastatic UCB patients were included. Among them, 146 patients underwent urethrectomy at the time of RC. Urethrectomy was performed more often in patients with urethral invasion, T3/4 tumor stage, CIS, positive frozen section analysis of the urethra, and those who received neoadjuvant chemotherapy, underwent robotic RC, and/or received an ileal conduit urinary diversion (all p < 0.001). Estimated blood loss and the postoperative complication rate were comparable between patients who received an urethrectomy and those who did not. Urethrectomy during RC was not associated with PFS (HR 0.83, p = 0.17), CSS (HR 0.93, p = 0.67), or OS (HR 1.08, p = 0.58). In the subgroup of 276 patients at high risk for UR, urethrectomy at the time of RC decreased the risk of progression (HR 0.58, p = 0.04). CONCLUSION: In our study, urethrectomy at the time of RC seems to benefit only patients at high risk for UR. Adequate risk assessment of UCB patients' history may allow for better clinical decision-making and patient counseling.

OBJECTIVE: To describe step-by-step surgical techniques and report outcomes of the largest single-centre series of patients with distal ureteric disease exclusively treated with robot-assisted ureteric reimplantation with Boari flap (RABFUR) and psoas hitch (RAPHUR), with a minimum follow-up of 1 year and complete postoperative data. PATIENTS AND METHODS: A total of 37 patients with distal ureteric disease were treated between 2010 and 2018. Of these, 81% and 19% underwent RAPHUR and RABFUR, respectively. Intra-, peri- and postoperative outcomes were assessed. The 90-day postoperative complications were reported according to the standardised methodology proposed by the European Association of Urology Ad Hoc Panel. Functional outcomes (creatinine, estimated glomerular filtration rate [eGFR]) and postoperative symptoms (visual analogue pain scale) were assessed. RESULTS: The median operating time and blood loss were 180 min and 100 mL, respectively. There were no conversions to open surgery and no intraoperative transfusions. The median length of stay, bladder catheter indwelling time and stent removal were 4, 7 and 30 days, respectively. The median follow-up was 24 months. Overall, 10 patients (27%) had postoperative complications and of these, eight (22%) and two (5.4%) were Clavien-Dindo Grade I-II and III, respectively. At the last follow-up, the median postoperative creatinine level and eGFR were 0.9 mg/dL and 73.5 mL/min/1.73 m2 , respectively. At the last follow-up, five (13.5%) and three (8%) patients had Grade 1 hydronephrosis and mild urinary symptoms, respectively. The study limitations include its retrospective nature. CONCLUSION: In the present study, we present our RABFUR and RAPHUR techniques. We confirm the feasibility and safety profile of both approaches in patients with distal ureteric disease relying on the largest single-centre series with ≥1 year of follow-up.

OBJECTIVES: To evaluate the postoperative complication and mortality rate following laparoscopic radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) in octogenarians. PATIENTS AND METHODS: We conducted a retrospective analysis comparing postoperative complication and mortality rates depending on age in a consecutive series of 1890 patients who underwent RARC with ICUD for bladder cancer between 2004 and 2018 in 10 European centres. Outcomes of patients aged <80 years and those aged ≥80 years were compared with regard to postoperative complications (Clavien-Dindo grading) and mortality rate. Cancer-specific mortality (CSM) and other-cause mortality (OCM) after surgery were calculated using the non-parametric Aalen-Johansen estimator. RESULTS: A total of 1726 patients aged <80 years and 164 aged ≥80 years were included in the analysis. The 30- and 90-day rate for high-grade (Clavien-Dindo grades III-V) complications were 15% and 21% for patients aged <80 years compared to 11% and 13% for patients aged ≥80 years (P = 0.2 and P = 0.03), respectively. In a multivariable logistic regression analysis adjusting for pre- and postoperative variables, age ≥80 years was not an independent predictor of high-grade complications (odds ratio 0.6, 95% confidence interval 0.3-1.1; P = 0.12). The non-cancer-related 90-day mortality was 2.3% for patients aged ≥80 years and 1.8% for those aged <80 years, respectively (P = 0.7). The estimated 12-month CSM and OCM rates for those aged <80 years were 8% and 3%, and for those aged ≥80 years, 15% and 8%, respectively (P = 0.009 and P < 0.001). CONCLUSIONS: The minimally invasive approach to RARC with ICUD for bladder cancer in well-selected elderly patients (aged ≥80 years) achieved a tolerable high-grade complication rate; the 90-day postoperative mortality rate was driven by cancer progression and the non-cancer-related rate was equivalent to that of patients aged <80 years. However, an increased OCM rate in this elderly group after the first year should be taken into account. These results will support clinicians and patients when balancing cancer-related vs treatment-related risks and benefits.

INTRODUCTION: The available studies comparing robot-assisted radical cystectomy (RARC) with intracorporeal (ICUD) vs. extracorporeal (ECUD) urinary diversion have not relied on a standardized methodology to report complications and did not assess the effect of different approaches on postoperative outcomes. MATERIALS: Two hundred and sixty seven patients treated with RARC at a single center were assessed. A retrospective analysis of data prospectively collected according to a standardized methodology was performed. Multivariable logistic regression models (MVA) assessed the impact of ICUD vs. ECUD on intraoperative complications, prolonged length of stay (LOS), 30-day Clavien Dindo (CD) ≥ 2 complications and readmission rate. Interaction terms tested the impact of the approach on different patient subgroups. Lowess graphically depicted the probability of CD ≥ 2 after ICUD or ECUD according to patient baseline characteristics. RESULTS: Overall, 162 ICUD vs 105 ECUD (61 vs. 39%) were performed. Intraoperative complications were recorded in 24 patients. The median LOS and readmission rate were 11 vs. 13 (p = 0.02) and 24 vs. 22% (p = 0.7) in ICUD vs. ECUD, respectively. Overall, 227 postoperative complications were recorded. The overall rate of CD ≥ 2 was 35 and 43% in patients with ICUD vs. ECUD, respectively (p = 0.2). At MVA, the approach type was not an independent predictor of any postoperative outcomes (all p ≥ 0.4). Age-adjusted Charlson Comorbidity Index (ACCI) was associated with an increased risk of CD ≥ 2 (OR: 1.2, p = 0.006). We identified a significant interaction term between ACCI and approach type (p = 0.04), where patients with ICUD had lower risk of CD ≥ 2 relative to those with ECUD with increasing ACCI. CONCLUSIONS: Relying on a standardized methodology to report complications, we observed that highly comorbid patients who undergo ICUD have lower risk of postoperative complications relative to those patients who received ECUD.

PURPOSE: To assess the available literature evidence that discusses the effect of surgical experience on patient outcomes in robotic setting. This information is used to help understand how we can develop a learning process that allows surgeons to maximally accommodate patient safety. METHODS: A literature search of the MEDLINE/PubMed and Scopus database was performed. Original and review articles published in the English language were included after an interactive peer-review process of the panel. RESULTS: Robotic surgical procedures require high level of experience to guarantee patient safety. This means that, for some procedures, the learning process might be longer than originally expected. In this context, structured training programs that assist surgeons to improve outcomes during their learning processes were extensively discussed. We identified few structured robotic curricula and demonstrated that for some procedures, curriculum trained surgeons can achieve outcomes rates during their initial learning phases that are at least comparable to those of experienced surgeons from high-volume centres. Finally, the importance of non-technical skills on patient safety and of their inclusion in robotic training programs was also assessed. CONCLUSION: To guarantee safe robotic surgery and to optimize patient outcomes during the learning process, standardized and validated training programs are instrumental. To date, only few structured validated curricula exist for standardized training and further efforts are needed in this direction.

PURPOSE: The aim of the current narrative review was to summarize the available evidence in the literature on artificial intelligence (AI) methods that have been applied during robotic surgery. METHODS: A narrative review of the literature was performed on MEDLINE/Pubmed and Scopus database on the topics of artificial intelligence, autonomous surgery, machine learning, robotic surgery, and surgical navigation, focusing on articles published between January 2015 and June 2019. All available evidences were analyzed and summarized herein after an interactive peer-review process of the panel. LITERATURE REVIEW: The preliminary results of the implementation of AI in clinical setting are encouraging. By providing a readout of the full telemetry and a sophisticated viewing console, robot-assisted surgery can be used to study and refine the application of AI in surgical practice. Machine learning approaches strengthen the feedback regarding surgical skills acquisition, efficiency of the surgical process, surgical guidance and prediction of postoperative outcomes. Tension-sensors on the robotic arms and the integration of augmented reality methods can help enhance the surgical experience and monitor organ movements. CONCLUSIONS: The use of AI in robotic surgery is expected to have a significant impact on future surgical training as well as enhance the surgical experience during a procedure. Both aim to realize precision surgery and thus to increase the quality of the surgical care. Implementation of AI in master-slave robotic surgery may allow for the careful, step-by-step consideration of autonomous robotic surgery.

The introduction of laparoscopy and robotic surgery revolutionized the surgical management of urologic patients. Nonetheless, we live in an era of rapid changes, and we are probably still in the infancy of technology applied to surgery. When considering currently available technologies, there are several unmet needs to be addressed. These include the application of augmented reality, haptic feedback, tissue recognition, distant remote control, miniaturization of surgical instruments, the learning curve typical of the introduction of novel techniques, and excessive costs. In the next few years, evolution in imaging modalities in pre- and intraoperative surgical planning, as well as the introduction of novel minimally invasive platforms, would in part address these issues, substantially improving surgical outcomes. In addition, validated training programs would allow for the safe implementation of novel techniques in the clinical practice. Finally, a reduction in costs would be necessary to make technology affordable and to optimize healthcare resources.

INTRODUCTION: Idiopathic partial thrombosis (IPT) of the corpus cavernosum is a rare condition. The etiology is not fully understood; however, the presence of an either or not congenital web in these patients may contribute to the development of IPT. AIM: The aim of this study was to describe 18 new IPT cases and compare these with 38 cases found in the literature. METHODS: A multicenter retrospective analysis was performed. Descriptive statistics are given. MAIN OUTCOME MEASURES: The main outcome measures used were clinical presentation, clinical and radiographical diagnostics, treatment and resolution of symptoms. RESULTS: Patients most frequently presented with perineal swelling (10/18; 56%) and pain (13/18; 72%), unilateral (12/18; 67%) or bilateral (4/18; 22%), and pain during erection (10/18; 72%). Penile curvature, dysuria or fever (each 1/18; 6%) were uncommon presenting symptoms. In our series, magnetic resonance imaging demonstrated a fibrous web in the corpus cavernosum in 100% of cases and was more bilaterally (11/18; 61%) than unilaterally (7/18; 39%) diagnosed. Cycling was found to be a provocative factor for IPT occurrence in patients at risk as 61% (11/18) of patients reported being a frequent cyclist with the episode of IPT occurring immediately after or during cycling activity in 8 out of 18 patients (8/18; 44%). In five centers, 15 patients were treated conservatively, the majority being treated with therapeutic doses of low molecular weight heparin and simultaneous anti-aggregant therapy. In one center, all three patients were treated with a surgical approach. Complete resolution of symptoms was noted in only 50% of cases. CONCLUSION: IPT is a condition that presents typically with perineal pain and swelling. Cycling is often seen as a provocative factor, while the presence of a fibrous web at the level of the crurocavernosal junction is the underlying disorder allowing for entrapment of blood in the crura. Conservative treatment provides a reasonably good outcome in most cases. For therapy resistant cases, surgery can be considered.

BACKGROUND: In the field of robotic surgery, there is a lack of comparative evidence on surgical and functional outcomes of different robotic platforms. OBJECTIVE: To assess the outcomes of patients receiving robot-assisted radical prostatectomy (RARP) at a high-volume robotic center with daVinci and HUGO robot-assisted surgery (RAS) surgical systems. DESIGN, SETTING, AND PARTICIPANTS: We analyzed the data of 542 patients undergoing RARP ± extended pelvic lymph node dissection at OLV hospital (Aalst, Belgium) between 2021 and 2023. All procedures were performed by six surgeons using daVinci or HUGO RAS robots; the use of one platform rather than the other did not follow any specific preference and/or indication. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable analyses investigated the association between robotic system (daVinci vs HUGO RAS) and surgical outcomes after adjustment for patient- and tumor-related factors. Urinary continence recovery was defined as the use of no/one safety pad. RESULTS AND LIMITATIONS: A total of 378 (70%) and 164 (30%) patients underwent RARP with daVinci and HUGO RAS surgical systems, respectively. Despite a higher rate of palpable disease in the HUGO RAS group (34% vs 25%), baseline characteristics did not differ between the groups (all p > 0.05). After adjusting for confounders, we did not find evidence of a difference between the groups with respect to operative time (estimate: 16.71; 95% confidence interval [CI]: -6.35, 39.78; p = 0.12), estimated blood loss (estimate: 3.12; 95% CI: -67.03, 73.27; p = 0.9), and postoperative Clavien-Dindo ≥2 complications (odds ratio [OR]: 1.66; 95% CI: 0.34, 8.15; p = 0.5). On final pathology, 55 (15%) and 20 (12%) men in, respectively, the daVinci and the HUGO RAS group had positive surgical margins (PSMs; p = 0.5). On multivariable analyses, we did not find evidence of an association between a robotic system and PSMs (OR: 1.08; 95% CI: 0.56, 2.07; p = 0.8). Similarly, the odds of recovering continence did not differ between daVinci and HUGO RAS cases after both 1 mo (OR: 0.78; 95% CI: 0.45, 1.38; p = 0.4) and 3 mo (OR: 1.17; 95% CI: 0.49, 2.79; p = 0.7). CONCLUSIONS: Among patients receiving RARP with daVinci or HUGO RAS surgical platforms, we did not find differences in surgical and functional outcomes between the robots. This may be a result of a standardized surgical technique that allowed surgeons to transfer their skills between robotic systems. Awaiting future investigations with longer follow-up, these results have important implications for patients, surgeons, and health care policymakers. PATIENT SUMMARY: We compared surgical and functional outcomes of patients receiving robot-assisted radical prostatectomy with daVinci versus HUGO robot-assisted surgery (RAS) robots. The two platforms were able to achieve similar outcomes, suggesting that the introduction of HUGO RAS is safe and allows for optimal outcomes after radical prostatectomy.

BACKGROUND: Multiple and heterogeneous techniques have been described for orthotopic neobladder (ONB) reconstruction after robot-assisted radical cystectomy. Nonetheless, a systematic assessment of all the available options is lacking. OBJECTIVE: To provide the first comprehensive step-by-step description of all the available techniques for robotic intracorporeal ONB together with individual intraoperative, perioperative and functional outcomes based on a systematic review of the literature. DESIGN, SETTING, AND PARTICIPANTS: We performed a systematic review of the literature, and MEDLINE/PubMed, Embase, Scopus, and Web of Science databases were searched to identify original articles describing different robotic intracorporeal ONB techniques and reporting intra- and perioperative outcomes. Studies were categorized according to ONB type, providing a synthesis of the current evidence. Video material was provided by experts in the field to illustrate the surgical technique of each intracorporeal ONB. SURGICAL PROCEDURE: Nine different ONB types were identified: Studer, Hautmann, Y shape, U shape, Bordeaux, Pyramid, Shell, Florence Robotic Intracorporeal Neobladder, and Padua Ileal Neobladder. MEASUREMENTS: Continuous and categorical variables are presented as mean ± standard deviation and as frequencies and proportions, respectively. RESULTS AND LIMITATIONS: Of 2587 studies identified, 19 met our inclusion criteria. No cohort studies or randomized control trials comparing different neobladder types are available. Available techniques for intracorporeal robotic ONB reconstruction have similar operative time, estimated blood loss, intraoperative complications, and length of stay. Major variability exists concerning postoperative complications and functional outcomes, likely related to reporting bias. CONCLUSIONS: Several techniques are described for intracorporeal ONB during robot-assisted radical cystectomy with comparable perioperative outcomes. We provide the first step-by-step surgical atlas for robot-assisted ONB reconstruction. Further comparative studies are needed to assess any advantage of one technique over others. PATIENT SUMMARY: Patients elected for radical cystectomy should be aware that multiple techniques for robotic orthotopic neobladder are available, but that current evidence does not favor one type over the others.

OBJECTIVES: An increasing number of urologists is switching from transrectal (TR) to transperineal (TP) biopsy procedures for the diagnosis of prostate cancer. Local anesthesia (LA) might be advantageous in terms of patient management, risks and costs. We aimed to evaluate the tolerability and complication rates of TP prostate biopsy performed under LA. METHODS: This is a monocentric, prospective, comparative, observational cohort study. Between July 2020 and July 2021 we included 128 consecutive patients (TR, nâ¯=â¯61; TP, nâ¯=â¯67), with a suspicion of prostate cancer. Transrectal vs. transperineal prostate biopsies were both performed under LA. To evaluate the tolerability we administered a validated visual analog pain score (VAS) during the different steps of the biopsy procedure as well as at 12-, 24- and 48-hours post procedure. The International Prostate Symptom Score (IPSS) questionnaire was administered before the procedure and at the same time intervals. The presence of hematuria, hematospermia, rectal blood loss, acute retention and febrile urinary tract infection (UTI) were also monitored. RESULTS: There were no significant differences in pain or IPSS between groups, except for a significantly higher pain score during the LA of the prostate in the TP group. In general, complication rates were similar, only the prevalence of hematuria at 24 hours was significantly higher in the TP group, as was rectal blood loss at 12 hours postprocedure in the TR group. CONCLUSIONS: In conclusion, our study showed that transperineal prostate biopsy under local anesthesia could be performed with similar pain scores and complication rates, compared to the transrectal procedure.

Clinical data on robot-assisted radical prostatectomy (RARP) performed with the new Hugo robot-assisted surgery (RAS) system are scarce. We described surgical outcomes of 112 consecutive patients who underwent RARP ± extended pelvic lymph-node dissection (ePLND) at OLV Hospital (Aalst, Belgium) between February and November 2022. The median age was 65 yr (interquartile range [IQR] 60-70) and median preoperative prostate-specific antigen (PSA) was 7.9 ng/ml (5.8-10.7). Thirty-eight patients (34%) had International Society of Urological Pathology grade group ≥3 tumor on prostate biopsy. On preoperative magnetic resonance imaging, 26 (23%) patients had a suspicion of extraprostatic disease. The median operative time was 180 min (IQR 145-200) and 27 men (24%) underwent ePLND. On final pathology, 34 patients (31%) had extraprostatic disease and ten (9%) had positive surgical margins. The median number of nodes removed was 15 (IQR 9-19). Among men with data available on the first PSA after surgery, 88% (60/68) had undetectable PSA (<0.1 ng/ml). The probability of urinary continence (UC) recovery was 36% (95% confidence interval [CI] 28-47%) at 1 mo and 81% (95% CI 72-89%) at 3 mo. The median time to UC recovery was 36 d (95% CI 34-44). This is the first report of data on UC recovery and surgical pathology for patients undergoing RARP for prostate cancer performed with the Hugo RAS robotic system. Future investigations with longer follow-up are awaited. PATIENT SUMMARY: We describe surgical outcomes of patients undergoing robot-assisted surgical removal of the prostate for cancer performed with the Hugo RAS robotic system at our institution. In our experience this platform provided adequate results in terms of surgical results and early recovery of urinary continence. Studies with longer follow-up are awaited.

Background: Robot-assisted repair of benign ureteroenteric anastomotic strictures (UAS) provides an alternative to the open approach. We aimed to report short-, medium-, and long-term outcomes for robotic repair of benign UAS, and to provide a detailed video demonstration of critical operative techniques in performing this procedure robotically. Materials and Methods: Between January 2013 and September 2022, 31 patients from seven institutions who previously underwent radical cystectomy and subsequently developed UAS underwent robotic repair of UAS. Perioperative variables were prospectively collected, and postoperative outcomes were assessed. The surgery starts with a lysis of adhesions after previous surgery. Ureters are dissected, and the level of the stricture is identified. The ureter is then divided, and the stricture is resected. Finally, the ureter is spatulated and reimplanted with Nesbit technique after stenting with Double-J stents. In cases where both ureters show strictures, Wallace technique for reimplantation can be applied. Results: After robotic or open cystectomy, 31 patients had a total of 43 UAS at a median (interquartile range) follow-up of 21 (9-43) months. Median stricture length was 2.0 (1.0-3.25) cm, operative duration was 141 (121-232) minutes, estimated blood loss was 100 (50-150) mL, and length of hospital stay was 5 (3-9) days. One (3.2%) case was converted to open and one (3.2%) intraoperative complication occurred. Seven (22.6%) patients experienced postoperative complications, including four (12.9%) Clavien-Dindo grade 3 complications. No Clavien-Dindo grade 4 or 5 complications occurred. Stricture recurrence occurred in 2 (6.5%) patients. Conclusions: These results demonstrate that robotic repair of UAS is feasible and effective approach with outcomes in line with prior open series. Patient Consent Statement: Authors have received and archived patient consent for video recording and publication in advance of video recording of procedure.

Objective: In the last years, robotic surgery was introduced in several different settings with good perioperative results. However, its role in the management of adrenal masses is still debated. In order to provide a contribution to this field, we described our step-by-step technique for robotic adrenalectomy (RA) and related modifications according to the type of adrenal mass treated. Methods: We retrospectively analyzed 27 consecutive patients who underwent RA at Onze-Lieve-Vrouw hospital (Aalst, Belgium) between January 2009 and October 2022. Demographic, intra- and post-operative, and pathological data were retrieved from our prospectively maintained institutional database. Continuous variables are summarized as median and interquartile range (IQR). Categorical variables are reported as frequencies (percentages). Results: Twenty-seven patients underwent RA were included in the study. Median age, body mass index, and Charlson's comorbidity index were 61 (IQR: 49-71) years, 26 (IQR: 24-29) kg/m2, and 2 (IQR: 0-3), respectively, and 16 (59.3%) patients were male. Median tumor size at computed tomography scan was 6.0 (IQR: 3.5-8.0) cm. Median operative time and blood loss were 105 (IQR: 82-120) min and 175 (IQR: 94-250) mL, respectively. No intraoperative complications were recorded. Overall postoperative complications rate was 11.1%, with a postoperative transfusion rate of 3.7%. A total of 10 (37.0%) patients harbored malignant adrenal masses. Among them, 3 (11.1%) had adrenocortical carcinoma, 6 (22.2%) secondary metastasis, and 1 (3.7%) malignant pheochromocytoma on final pathological exam. Only 1 (10.0%) patient had positive surgical margins. Conclusion: We described our step-by-step technique for RA, which can be safely performed even in case of high challenging settings as malignant tumors, pheochromocytoma, and large masses. The standardization of perioperative protocol should be encouraged to maximize the outcomes of this complex surgical procedure.
RESUMO
Introduction and Objectives: Robot-assisted simple prostatectomy (RASP) and holmium laser enucleation of the prostate (HoLEP) are both well-established, minimally invasive surgical treatment options for lower urinary tract symptoms caused by benign prostatic enlargement. We have reported the first comparative analysis of both techniques in patients with prostates of ≥200 cc. Materials and Methods: Between 2009 and 2020 a total of 53 patients with a prostate volume of ≥200 cc were surgically treated at OLV Hospital Aalst (Belgium): 31 underwent RASP and 22 underwent HoLEP. Preoperative and postoperative assessments included uroflowmetry with maximum urinary flow rate (Qmax) and postvoid residual volume (PVR), as well as the International Prostate Symptom Score (IPSS) and quality of life (IPSS-QoL). The complication rates were evaluated according to the Clavien-Dindo Classification. Results: Patients treated with RASP had significantly larger prostate volumes compared with HoLEP (median 226 cc vs 204.5 cc, p = 0.004). After a median follow-up of 14 months, both groups showed a significant improvement in the maximum flow rate (+10.60 mL/s vs +10.70 mL/s, p = 0.724) and a reduction of the IPSS score (-12.50 vs -9, p = 0.246) as well as improvement of the QoL (-3 vs -3, p = 0.880). Median operative time was similar in both groups (150 minutes vs 132.5 minutes, p = 0.665). The amount of resected tissue was lower in the RASP group (134.5 g vs 180 g, p = 0.029) and there was no significant difference in postoperative prostate-specific antigen (1.2 ng/mL vs 0.8 ng/mL, p = 0.112). Despite a similar median catheterization time (3 days vs 2 days, p = 0.748), the median hospitalization time was shorter in the HoLEP group (4 days vs 3 days, p = 0.052). Complication rates were similar in both groups (32% vs 36%, p = 0.987). Conclusion: Our results suggest similar outcomes for RASP and HoLEP in patients with very large prostates ≥200 cc. These findings will require external validation at other high-volume centers.
