We conducted a retrospective analysis of preoperative planning, intraoperative records, and postoperative imaging data from patients who underwent RATHA. We predicted prosthesis sizes using both traditional 2D methods and robotic systems, comparing their accuracy. The cases were categorized into four groups based on the consistency between the robotic planned and applied femoral sizes: matched group, reduced group, enlarged group, and deviated group. The postoperative measurements of stem position were compared across these groups. The prediction accuracy of the robotic system for the acetabular cup (90.3% vs. 69.7%, P < 0.01) and femoral stem (75.7% vs. 59.5%, P < 0.01) was significantly higher than that of the traditional 2-D method. The absolute values of coronal plane angulation (CA) varied significantly among the three groups: 0.55° (0.15°-1.08°) in the enlarged group, 1.25° (0.40°-2.40°) in the matched group, and 2.55° (1.45°-3.13°) in the reduced group (P < 0.001). The safe zone ratio was higher in the enlarged (100%, P < 0.01) and matched groups (83.6%, P < 0.01) compared to the reduced group (60.7%). A larger stem was associated with a higher canal fill ratio (CFR) in planes C (P = 0.02) and D (P < 0.01). All data from the deviated group differed significantly from those of the other three groups. The robotic system provides a more accurate prediction of prosthesis size compared to traditional methods. The use of a smaller stem than planned was linked to a larger absolute CA and a smaller CFR. Conversely, applying a larger stem facilitates a more neutral stem position and improved press fitting. If the applied size is reduced by two or more compared to the postoperative plan, poor positioning of the femoral prosthesis should be suspected.</p>","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"409"},"PeriodicalIF":2.2,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144676163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While robot-assisted surgery (RAS) offers potential advantages through 3D high-definition imaging and tremor filtering capabilities, comprehensive safety data for obese patients remains limited. This study aimed to evaluate the safety profile and complication spectrum of robotic surgery in obese patients. A retrospective observational study was conducted at the First Affiliated Hospital of Anhui Medical University from January 2019 to March 2025. Inclusion criteria were age ≥ 18 years, BMI ≥ 28 kg/m², and da Vinci robotic system-assisted surgery. Clinical data including patient characteristics, surgical outcomes, and complications were analyzed. Patients were stratified by obesity severity: mild (28 ≤ BMI < 32.5 kg/m²), moderate (32.5 ≤ BMI < 37.5 kg/m²), and severe (37.5 ≤ BMI < 50 kg/m²). A total of 299 obese patients were included: 109 underwent radical prostatectomy, 150 partial nephrectomy, and 40 ureteral reconstruction. No robotic malfunctions or conversions to open surgery occurred. Overall complication rates were low, with incisional pain (5.7%) and fever (2.3%) being most common. Complications were predominantly Clavien-Dindo grades I and II. Serious complications including pulmonary embolism (0.3%), delayed bleeding (0.3%), and critical myoglobin value (0.3%) occurred rarely. BMI subgroup analysis revealed complication rates of 11.3% in mild obesity, 5.3% in moderate obesity, and 0% in severe obesity, suggesting higher BMI did not increase complication rates. Robot-assisted surgery demonstrates a high safety profile in obese patients with low overall complication rates. While most complications were minor and manageable, attention should be paid to postoperative pain management, infection prevention, and thromboembolic risk assessment. These findings support the safety and feasibility of robotic surgery in the obese population.</p>","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"407"},"PeriodicalIF":2.2,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144676164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We distributed a Qualtrics survey to U.S. urology residency program directors to assess the presence and structure of robotic simulation curricula. If a program director did not respond, an email was sent to the program coordinator to survey them on the presence and structure of a curriculum. We surveyed only program directors' views of simulation training and assessed their responses using a 5-point Likert scale. Surveys were sent to 150 programs, with 33 (22%) responding; 17 program directors (51.5%) and 16 coordinators (48.5%). Of the responding programs, 31/33 (93.9%) reported access to and utilization of robotic simulation training. Simulation training was mandatory for residents in 21/31 (67.7%) of these programs. Structured curricula with objectives were reported by 16/31 programs (51.6%), while 15/31 (48.4%) relied on informal or self-directed methods. Supervised simulation training was reported by 24/31 programs (77.4%). Program directors viewed simulation training as beneficial, with an average agreement rating of 4.18/5 for its educational role and impact on performance.

This study evaluates three robotic techniques-robotic transabdominal preperitoneal (rTAPP), robotic Rives (rRives), and robotic transabdominal retromuscular umbilical prosthetic (rTARUP)-for treating primary ventral and incisional hernias. Following PRISMA guidelines, a systematic review and meta-analysis were conducted. Databases such as PubMed, Embase, Cochrane Library, and Web of Science were searched for studies comparing rTAPP, rRives, and rTARUP. Key outcomes included recurrence rates, surgical duration, and postoperative complications, with secondary outcomes assessing hospital stay and cost-effectiveness. Statistical analyses were performed using RevMan 5.4 and STATA 16, calculating pooled odds ratios (OR) and mean differences (MD). Heterogeneity was measured via I² statistics, and publication bias was evaluated using the Egger test. The analysis included 18 studies encompassing 1,500 patients. rTAPP showed shorter operative times (MD: - 25.3 min, 95% CI: - 30.1 to - 20.5, *p* < 0.05) and reduced recurrence rates (OR: 0.45, 95% CI: 0.30-0.68, *p* < 0.01) compared to rRives and rTARUP. However, rTARUP was linked to fewer postoperative complications (OR: 0.65, 95% CI: 0.50-0.85, *p* < 0.05). No significant publication bias was detected (Egger test, *p* = 0.12).

A kidney-shaped urethane resin model with surface markers was created to measure deformation. Three-dimensional scanning assessed deformation before and after suturing. Strain values were calculated using finite-element shape functions on a triangular mesh. Distance from the centerline of the suture was also measured. The standard suturing method was defined as continuous stitches using self-retaining barbed sutures. Based on this standard, variations were introduced in suture material, suturing technique (continuous or interrupted), number of stitches, and the distance from the defect edge. Seven suture patterns were tested. Deformation values were higher when sutures were placed farther from the defect margin and lower when placed closer. Interrupted, tight, sparse, and multifilament suture patterns produced strain values similar to those of the standard technique. Narrow suture pattern tended to have longer distances from the centerline than the wide suture pattern. Interrupted and multifilament suture patterns also showed slightly longer distances than the standard pattern. This is the first study to visualize and quantify strain distribution during renorrhaphy using deformation values. The findings suggest that the distance of suture placement from the limbus may impact parenchymal strain.
