RESUMO
OBJECTIVE: We present a novel technique to perform single-port (SP) robot-assisted partial cystectomy with excision of the urachal remnant and bilateral pelvic lymph node dissection for urachal adenocarcinoma (1-7). MATERIALS AND METHODS: A 41-year-old male presented to the clinic for multiple episodes of hematuria and mucousuria. Office cystoscopy revealed a small solitary tumor at the dome of the bladder, with a diagnostic bladder biopsy revealing a tubule-villous bladder adenoma. Cross-sectional imaging of the chest/abdomen/pelvis revealed a 4.5 cm cystic mass arising from the urachus without evidence of local invasion and metastatic spread. He underwent SP robotic-assisted partial cystectomy with excision of the urachal remnant and bilateral pelvic lymph node dissection. Surgical steps include: 1) peritoneal incision to release the urachus and drop bladder 2) identification of urachal tumor 3) intraoperative live cystoscopic identification of bladder mass and scoring of tumor margins using Toggle Pro feature 4) tumor excision with partial cystectomy 5) cystorrhaphy 6) bilateral pelvic lymph node dissection 7) peritoneal interposition flap to mitigate lymphocele formation. RESULTS: Surgery was successful, with no intraoperative complications, an operative time of 100 minutes, and estimated blood loss of 20 mL. The patient was discharged on post-op day one, and the Foley catheter removed one week after surgery. Final pathology revealed a 7.5 cm infiltrating urachal muscle-invasive adenocarcinoma of the bladder (pT2b). Negative surgical margins were achieved. CONCLUSIONS: Single-port robot-assisted partial cystectomy for urachal adenocarcinoma is safe and can achieve equivalent oncologic outcomes to the standard of care with minimally invasive and open techniques.

Robotic surgery is a rapidly expanding field, given the wide variety of new robotic platforms emerging. Looking at the training of surgeons in robotic surgery is of extreme necessity and urgency, considering the ongoing technological advancements. In this research, the performance during the virtual reality simulation phase of training for robotic surgery was analyzed. It was observed that, in addition to the lack of consensus among societies regarding the required simulation hours, there is no guidance on the best curriculum to be adopted. From the data in this study, it can be inferred that the more advanced skills have fewer proficient individuals, meaning that fewer surgeons in training have reached proficiency in all skill exercises. Even with differences in the number of exercises performed proficiently between groups that underwent varying amounts of simulation time, there is no statistically significant difference in the proportion between them.

PURPOSE: Minimally invasive radical nephrectomy is often preferred for larger renal tumours not suitable for partial nephrectomy (1). When performed with a multiport robot, the procedure is routinely performed with a transperitoneal approach, with recent studies highlighting important factors for surgical outcomes, including predictive factors (2), segmental artery unclamping techniques (3), and comparisons of robotic techniques (4). This video shows that SP Robot-Assisted Radical Nephrectomy (RARN) via a lower anterior approach is valuable in challenging cases. MATERIALS AND METHODS: We performed SP-RARN on two complex patients using a retroperitoneal lower anterior approach. The first patient, a 54-year-old female with a BMI of 36.8 kg/m², had a ventral hernia and bowel obstruction history, with a 9 cm right middle kidney mass. The second patient, a 58-year-old male with a BMI of 31.19 kg/m², had ESRD and was on peritoneal dialysis for 8 years, with a 3.4x3.7 cm mass in the right superior pole, suspected to be RCC. The surgical technique is detailed in the video. RESULTS: Both procedures were successful, with operative times of 173 and 203 minutes and blood loss of 150 mL. No complications occurred. Patients were discharged after 31 and 38 hours, respectively. Histopathology confirmed RCC. At the 3-month follow-up, no complications or readmissions were reported. Second patient continued peritoneal dialysis without issues. CONCLUSION: Retroperitoneal SP-RARN via the lower anterior approach avoids the peritoneal cavity, making it suitable for certain patients. In these patients, more so than in others, this procedure is feasible, safe, and less morbid than the standard multiport approach.

INTRODUCTION: We aim to compare the safety and effectiveness of the KangDuo (KD)-Surgical Robot-01 (KD-SR-01) system and the da Vinci (DV) system for robot-assisted radical nephroureterectomy (RARNU). MATERIALS AND METHODS: This multicenter prospective randomized controlled trial was conducted between March 2022 and September 2023. Group 1 included 29 patients undergoing KD-RARNU. Group 2 included 29 patients undergoing DV-RARNU. Patient demographic and clinical characteristics, perioperative data, and follow-up outcomes were collected prospectively and compared between the two groups. RESULTS: There were no significant differences in patient baseline demographic and preoperative characteristics between the two groups. The success rates in both groups were 100% without conversion to open or laparoscopic surgery or positive surgical margins. No significant difference was observed in docking time [242 (120-951) s vs 253 (62-498) s, P = 0.780], console time [137 (55-290) min vs 105 (62-220) min, P = 0.114], operative time [207 (121-460) min vs 185 (96-305) min, P = 0.091], EBL [50 (10-600) mL vs 50 (10-700) mL, P = 0.507], National Aeronautics and Space Administration Task Load Index scores, and postoperative serum creatinine levels between the two groups. None of the patients showed evidence of distant metastasis, local recurrence, or equipment-related adverse events during the four-week follow-up. One (3.4%) patient in Group 2 experienced postoperative enterovaginal and enterovesical fistulas (Clavien-Dindo grade III). CONCLUSIONS: The KD-SR-01 system is safe and effective for RARNU compared to the DV Si or Xi system. Further randomized controlled studies with larger sample sizes and longer durations are required.

PURPOSE: To describe a single-center experience with robotic-assisted endovascular treatment for transplant renal artery stenosis. MATERIALS AND METHODS: This is a single-center, retrospective, feasibility study of 4 consecutive cases of robotic-assisted endovascular surgery for transplant renal artery stenosis from October 2021 to August 2022. RESULTS: All lesions were identified, and stenting was performed with no complications. Conversion to manual control was not necessary. The mean fluoroscopy time was 25.25 min (range 12-60.9). A control Doppler ultrasound was routinely performed, demonstrating no residual lesions in all cases. There was no reintervention during the follow-up period. The operator learning curve was felt to be acceptable. CONCLUSION: Robotic-assisted endovascular treatment is a feasible technique for transplant renal artery stenosis.

Laparoscopic cholecystectomy (LC) is the established gold standard treatment for benign gallbladder diseases. However, robotic cholecystectomy is still controversial. Therefore, we aimed to compare intraoperative and postoperative outcomes in LC and robotic-assisted cholecystectomy (RAC) in patients with nonmalignant gallbladder conditions. PubMed, Scopus, Cochrane Library, and Web of Science were systematically searched for studies comparing RAC to LC in patients with benign gallbladder disease. Only randomized trials and non-randomized studies with propensity score matching were included. Mean differences (MDs) were computed for continuous outcomes and odds ratios (ORs) for binary endpoints, with 95% confidence intervals (CIs). Heterogeneity was assessed with I2 statistics. Statistical analysis was performed using Software R, version 4.2.3. A total of 13 studies comprising 22,440 patients were included, of whom 10,758 patients (47.94%) underwent RAC. The mean age was 48.5 years and 65.2% were female. Compared with LC, RAC significantly increased operative time (MD 12.59 min; 95% CI 5.62-19.55; p < 0.01; I2 = 79%). However, there were no significant differences between the groups in hospitalization time (MD -0.18 days; 95% CI - 0.43-0.07; p = 0.07; I2 = 89%), occurrence of intraoperative complications (OR 0.66; 95% CI 0.38-1.15; p = 0.14; I2 = 35%) and bile duct injury (OR 0.99; 95% CI 0.64, 1.55; p = 0.97; I2 = 0%). RAC was associated with an increase in operative time compared with LC without increasing hospitalization time or the incidence of intraoperative complications. These findings suggest that RAC is a safe approach to benign gallbladder disease.

Long-term postoperative complications of metabolic and bariatric surgery (MBS) are more frequent than those of primary surgery. Robotic-assisted procedures offer several advantages over traditional laparoscopy, but there are limited data. A retrospective study of 29 patients who underwent a revisional robotic-assisted Roux-en-Y gastric bypass (RRYGB) in a Tertiary Level Hospital. Variables included were demographics, causes for revision, operative details, complications, and weight loss outcomes up to 54 month post-RRYGB. Causes for conversion were weight loss failure (WLF), weight regain (WR), Gastroesophageal Reflux Disease (GERD), or Joint Pain (JP). We assessed 29 patients. Causes for conversion included WLF (34%), WR (15%), WR with GERD (20%), GERD (24%), and JP (3%). Initial BMI was 53.43 kg/m2 ± 8.75. Mean length of hospital stay (LOS) was 2 days. Total operative time was 126 min. ± 43.45. Excess weight loss at 1 year post-surgery was 82.66% (p < 0.0001), with mean BMI of 30.93 kg/m2 (p < 0.001). At 3 years, mean %EWL was 71.26% and a mean BMI 33.81 kg/m2 (p < 0.0001). At 4.5 years, mean %EWL was 59.29% and mean BMI 37.27 kg/m2 (p < 0.0001). One complication (8%) was found (jejunojejunal stenosis). There was no mortality. The initial experience with RRYGB shows acceptable outcomes, including low morbidity, no mortality, excellent weight loss after the revisional surgery, and promising reduction in operative times, with important implications on reduction of the total cost of the procedure.

PURPOSE: Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized setting. MATERIALS AND METHODS: In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1). The primary outcome was 90-day complication rates. Functional outcomes and quality of life were assessed over 18 months, and oncological outcomes, biochemical recurrence-free survival, and additional treatment over 36 months. RESULTS: From 2014 to 18, 327 patients underwent surgery (retropubic radical prostatectomy = 156, RALP = 171). Complications occurred in 27 (17.3%) vs 19 (11.1%; P = .107). Patients undergoing RALP experienced lower median bleeding (250.0 vs 719.5 mL; P < .001) and shorter hospitalization time. Urinary EPIC (Expanded Prostate Cancer Index Composite) median scores were better for RALP over 18 months, with higher continence rate at 3 months (80.5% vs 64.7%; P = .002), 6 months (90.1% vs 81.6%; P = .036) and 18 months (95.4% vs 78.8%; P < .001). Sexual EPIC and Sexual Health Inventory for Men median scores were higher with RALP up to 12 months, while the potency rate was superior at 3 months (23.9% vs 5.3%; P = .001) and 6 months (30.6% vs 6.9%; P < .001). Quality of life over the 18 months and oncological outcomes over 36 months were not significantly different between arms. CONCLUSIONS: Complications at 90 days were similar. RALP showed superior sexual outcomes at 1 year, improved urinary outcomes at 18 months, and comparable oncological outcomes at 36 months.
