RESUMO
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.

BACKGROUND: The evidence of prognostic factors and individualized surveillance strategies for upper tract urothelial carcinoma are still weak. OBJECTIVES: To evaluate whether the history of previous malignancy (HPM) affects the oncological outcomes of upper tract urothelial carcinoma (UTUC). METHODS: The CROES-UTUC registry is an international, observational, multicenter cohort study on patients diagnosed with UTUC. Patient and disease characteristics from 2380 patients with UTUC were collected. The primary outcome of this study was recurrence-free survival. Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to their HPM. RESULTS: A total of 996 patients were included in this study. With a median recurrence-free survival time of 7.2 months and a median follow-up time of 9.2 months, 19.5% of patients had disease recurrence. The recurrence-free survival rate in the HPM group was 75.7%, which was significantly lower than non-HPM group (82.7%, P = 0.012). Kaplan-Meier analyses also showed that HPM could increase the risk of upper tract recurrence (P = 0.048). Furthermore, patients with a history of non-urothelial cancers had a higher risk of intravesical recurrence (P = 0.003), and patients with a history of urothelial cancers had a higher risk of upper tract recurrence (P = 0.015). Upon multivariate Cox regression analysis, the history of non-urothelial cancer was a risk factor for intravesical recurrence (P = 0.004), and the history of urothelial cancer was a risk factor for upper tract recurrence (P = 0.006). CONCLUSION: Both previous non-urothelial and urothelial malignancy could increase the risk of tumor recurrence. But different cancer types may increase different sites' risk of tumor recurrence for patients with UTUC. According to present study, more personalized follow-up plans and active treatment strategies should be considered for UTUC patients.

OBJECTIVE: To externally validate Yonsei nomogram. METHODS: From 2000 through 2018, 3526 consecutive patients underwent on-clamp PN for cT1 renal masses at 23 centers were included. All patients had two kidneys, preoperative eGFR ≥60 ml/min/1.73 m2, and a minimum follow-up of 12 months. New-onset CKD was defined as upgrading from CKD stage I or II into CKD stage ≥III. We obtained the CKD-free progression probabilities at 1, 3, 5, and 10 years for all patients by applying the nomogram found at https://eservices.ksmc.med.sa/ckd/. Thereafter, external validation of Yonsei nomogram for estimating new-onset CKD stage ≥III was assessed by calibration and discrimination analysis. RESULTS AND LIMITATION: Median values of patients' age, tumor size, eGFR and follow-up period were 47 years (IQR: 47-62), 3.3 cm (IQR: 2.5-4.2), 90.5 ml/min/1.73 m2 (IQR: 82.8-98), and 47 months (IQR: 27-65), respectively. A total of 683 patients (19.4%) developed new-onset CKD. The 5-year CKD-free progression rate was 77.9%. Yonsei nomogram demonstrated an AUC of 0.69, 0.72, 0.77, and 0.78 for the prediction of CKD stage ≥III at 1, 3, 5, and 10 years, respectively. The calibration plots at 1, 3, 5, and 10 years showed that the model was well calibrated with calibration slope values of 0.77, 0.83, 0.76, and 0.75, respectively. Retrospective database collection is a limitation of our study. CONCLUSIONS: The largest external validation of Yonsei nomogram showed good calibration properties. The nomogram can provide an accurate estimate of the individual risk of CKD-free progression on long-term follow-up.

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.

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.

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.

OBJECTIVE: To determine the impact of imperative or elective indications on the perioperative, functional and oncological outcomes of patients undergoing robot-assisted partial nephrectomy. METHODS: Between June 2006 and September 2016, data of patients who underwent robot-assisted partial nephrectomy at the Onze-Lieve-Vrouwziekenhuis Hospital in Aalst, Belgium, were retrospectively reviewed from a prospectively collected database. Only patients with non-metastatic, clinical T1-T2 graded tumors were included. Perioperative, functional and oncological outcomes were recollected. A comparative analysis was carried out after dividing patients into two groups: those who underwent robot-assisted partial nephrectomy for an elective indication (group 1, n = 194), and for an imperative indication (group 2, n = 57) caused by a solitary kidney (n = 20), impaired renal function (n = 2) or both (n = 35). RESULTS: Patients in group 2 were older (74 vs 71 years, P < 0.001), and had a higher Charlson Comorbidity Index (P < 0.001) and American Society of Anesthesiologists score (P < 0.001). No differences were observed concerning laterality, sex, preoperative aspects and dimensions used for an anatomical score or clinical stage. Surgical outcomes considering estimated blood loss, surgical time, ischemia time and transfusion rate showed no significant difference between groups. The complication rate according to Clavien-Dindo showed no difference between groups (P = 0.6). No difference was found between groups with regard to percentage decrease of estimated glomerular filtration rate (7.4 vs 4.8%, P < 0.15). CONCLUSIONS: Robot-assisted partial nephrectomy can be safely and effectively carried out by experienced surgeons in a high-volume center with similar perioperative, functional and oncological outcomes for both elective or imperative indications.

PURPOSE: We report a comparative analysis of robotic assisted simple prostatectomy vs holmium laser enucleation of the prostate in patients who had benign prostatic hyperplasia with a large volume prostate (greater than 100 ml). MATERIALS AND METHODS: A total of 81 patients underwent robotic assisted simple prostatectomy and 45 underwent holmium laser enucleation of the prostate in a 7-year period. Patients were preoperatively assessed with transrectal ultrasound and uroflowmetry. Functional parameters were assessed postoperatively during followup. Perioperative outcomes included operative time, postoperative hemoglobin, catheterization time and hospitalization. Complications were reported according to the Clavien-Dindo classification. RESULTS: Compared to the holmium laser enucleation group, patients treated with prostatectomy were significantly younger (median age 69 vs 74 years, p = 0.032) and less healthy (Charlson comorbidity index 2 or greater in 62% vs 29%, p = 0.0003), and had a lower rate of suprapubic catheterization (23% vs 42%, p = 0.028) and a higher preoperative I-PSS (International Prostate Symptom Score) (25 vs 21, p = 0.049). Both groups showed an improvement in the maximum flow rate (15 vs 11 ml per second, p = 0.7), and a significant reduction in post-void residual urine (-73 vs -100 ml, p = 0.4) and I-PSS (-20 vs -18, p = 0.8). Median operative time (105 vs 105 minutes, p = 0.9) and postoperative hemoglobin (13.2 vs 13.8 gm/dl, p = 0.08) were similar for robotic assisted prostatectomy and holmium laser enucleation, respectively. Median catheterization time (3 vs 2 days, p = 0.005) and median hospitalization (4 vs 2 days, p = 0.0001) were slightly shorter in the holmium laser group. Complication rates were similar with no Clavien grade greater than 3 in either group. CONCLUSIONS: Our results from a single center suggest comparable outcomes for robotic assisted simple prostatectomy and holmium laser enucleation of the prostate in patients with a large volume prostate. These findings require external validation at other high volume centers.

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.

OBJECTIVE: To evaluate the perioperative, postoperative and functional outcomes of robot-assisted partial nephrectomy (RAPN) for renal tumours with high surgical complexity at a large volume centre. PATIENTS AND METHODS: Perioperative and functional outcomes of RAPNs for renal tumours with a Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score of ≥10 performed at our institution between September 2006 and December 2012 were collected in a prospectively maintained database and analysed. Surgical complications were graded according to the Clavien-Dindo classification. Serum creatinine and estimated glomerular filtration rate (eGFR) were assessed at the third postoperative day and 3-6 months after RAPN. RESULTS: In all, 44 RAPNs for renal tumours with PADUA scores of ≥10 were included in the analysis; 23 tumours (52.3%) were cT1b. The median (interquartile range; range) operative time, estimated blood loss and warm ischaemia time (WIT) were 120 (94, 132; 60-230) min, 150 (80, 200; 25-1200) mL and 16 (13.8, 18; 5-35) min, respectively. Two intraoperative complications occurred (4.5%): one inferior vena caval injury and one bleed from the renal bed, which were both managed robotically. There were postoperative complications in 10 patients (22.7%), of whom four (9.1%) were high Clavien grade, including two bleeds that required percutaneous embolisation, one urinoma that resolved with ureteric stenting and one bowel occlusion managed with laparoscopic adhesiolysis. Two patients (4.5%) had positive surgical margins (PSMs) and were followed expectantly with no radiological recurrence at a mean follow-up of 23 months. The mean serum creatinine levels were significantly increased after surgery (121.1 vs 89.3 µmol/L; P = 0.001), but decreased over time, with no significant differences from the preoperative values at the 6-month follow-up (96.4 vs 89.3 µmol/L; P = 0.09). The same trend was seen for eGFR. CONCLUSION: In experienced hands RAPN for renal tumours with a PADUA score of ≥10 is feasible with short WIT, acceptable major complication rate and good long-term renal functional outcomes. A slightly higher risk of PSMs can be expected due to the high surgical complexity of these lesions. The robotic technology allows a safe expansion of the indications of minimally invasive PN to anatomically very challenging renal lesions in referral centres.

Background: In February 2021 Medtronic® (Minneapolis, MN) launched the HUGO™ Robot-Assisted Surgery (RAS) System in the global market. The aim of the current study is to describe the first case series and the optimal setup of robot-assisted pyeloplasty procedure, performed with HUGO RAS system in a tertiary referral robotic center. Methods: Data from consecutive patients who underwent robot-assisted pyeloplasty at Onze-Lieve-Vrouwziekenhuis Hospital (Aalst, Belgium) were recorded. Baseline characteristics, and perioperative and surgical outcomes were collected. Results: Overall, 10 robot-assisted pyeloplasties were performed (October 2022-September 2023). Based on our expertise, the following minor setting changes have been made, relative to the official setup guide: the endoscope port and, subsequently, the left and right-hand ports were positioned more laterally. Additionally, the reserve/4th port was placed more laterally and cranially, and adjusted the arm cart's tilt angle, reducing it from -30° to -15°. The median docking time was 8 (interquartile range [IQR]: 7.2-9.8) minutes, and the median active console time was 89.5 (80.0-95.8) minutes. No conversion to open/laparoscopic surgery or perioperative complications was encountered. A single technical problem was recorded in 1 (10%) procedure. Specifically, one arm was blocked, and the procedure was accomplished with three arms without compromising the procedure success. Conclusions: This study represents the first worldwide series of robot-assisted pyeloplasty performed with the HUGO RAS system and shows promising results. The procedure might be safely performed with this robotic platform achieving optimal perioperative outcomes.

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.

OBJECTIVE: To report combined oncological and functional outcome in a series of patients who underwent robot-assisted radical prostatectomy (RARP) for clinically localised prostate cancer in a single European centre after 5-year minimum follow-up according to survival, continence and potency (SCP) outcomes. PATIENTS AND METHODS: We extracted from our prostate cancer database all consecutive patients with a minimum follow-up of 5 years after RARP. Biochemical failure was defined as a confirmed PSA concentration of >0.2 ng/mL. All patients alive at the last follow-up were evaluated for functional outcomes using the Expanded Prostate Cancer Index Composite (EPIC) and Sexual Health Inventory for Men (SHIM) questionnaires. Oncological and functional outcomes were reported according to the SCP system. Specifically, patients were classified as using no pad (C0), using one pad for security (C1), and using ≥1 pad (C2) (not including the prior definition). Patients potent (SHIM score of >17) without any aids were classified as P0 category; patients potent (SHIM score of >17) with use of phosphodiesterase type 5 inhibitorsas P1; and patients with erectile dysfunction (SHIM score of <17) as P2 category. Patients who did not undergo a nerve-sparing technique, who were not potent preoperatively, who were not interested in erections, or who did not have sexual partners were classified as Px category. RESULTS: The 3-, 5- and 7-year biochemical recurrence-free survival rates were 96.3%; 89.6% and 88.3%, respectively. At follow-up, 146 (79.8%) were fully continent (C0), 20 (10.9%) still used a safety pad (C1) and 17 (9.3%) were incontinent using ≥1 pad (C2). Excluding Px patients, 52 patients (47.3%) were classified as P0; 41 patients (37.3%) were classified as P1 and 17 patients (15.5%) were P2. In patients preoperatively continent and potent, who received a nerve-sparing technique and did not require any adjuvant therapy, oncological and functional success was attained by 77 (80.2%) patients. In the subgroup of 67 patients not evaluable for potency recovery (Px), oncological and continence outcomes were attained in 46 patients (68.7%). CONCLUSIONS: Oncological and functional success was attained in a high percentage of patients who underwent RARP at ≥5 years follow-up. Interestingly, this study confirmed that excellent oncological and functional outcomes can be obtained in the 'best' category of patients, i.e. those preoperatively continent and potent and with tumour characteristics suitable for a nerve-sparing technique.

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.

Robot-assisted simple prostatectomy (RASP) has demonstrated better peri-operative outcomes as compared to open simple prostatectomy. However, RASP is still limited by platform availability and cost-effectiveness issues. The new surgical robots increasing competition may spread the robotic approach also in non-oncological fields. We reported the first RASP executed in Europe at OLV Hospital (Aalst, Belgium) performed with the novel HUGO™ Robot-Assisted Surgery (RAS) System. The platform consists of four independent carts, an open console, and a system tower equipped for both laparoscopic and robotic surgery. Our main goal was to demonstrate the technical feasibility of RASP with the novel HUGO™ RAS along with its safety in terms of perioperative outcomes and complications. We also aimed to describe our surgical setup. We collected patient's baseline characteristics, intraoperative and perioperative complications, postoperative outcomes, docking time, operative time, clashing of the instruments, or technical errors of the system. The procedure was performed in a 72-year-old male with a prostate volume of 155 g at preoperative imaging. No need for conversion to open/laparoscopic surgery and/or for additional port placement was required. No intraoperative complications, instrument clashes, or failure of the system that compromised the completion of the surgery were recorded. Docking, operative, and console times were 9, 150, and 120 minutes, respectively. The catheter was removed on the second postoperative day. No postoperative complications occurred. The postoperative uroflowmetry revealed a maximum flow of 26.2 mL/s, without postvoid residual volume. Robot-assisted simple prostatectomy with the HUGO™ RAS System is a feasible and safe procedure in terms of perioperative outcomes and complications. Our setup allowed for a rapid docking procedure and a smoothly completion of the surgery.
