We searched PubMed/MEDLINE, Embase, Web of Science Core Collection and the Cochrane Library from inception to 31 July 2026, and included English-language studies that compared ureteral rest with immediate reconstruction. Studies without a no-rest comparator or without the key outcomes were excluded. Random-effects meta-analyses were performed in Review Manager 5.3 and R, using odds ratios (OR) or risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes. The review was registered with PROSPERO (registration number CRD420261504719). Five retrospective comparative studies including 707 patients (478 managed with preoperative ureteral rest and 229 managed without) were analysed. Preoperative ureteral rest was associated with a higher pooled surgical success rate (OR 2.82, 95% CI 1.57 to 5.07, P = 0.0005; 447/478 [93.5%] versus 198/229 [86.5%]; absolute risk difference + 7.6%, 95% CI 2.9% to 12.4%) and with a small reduction in estimated intraoperative blood loss (MD -23.91 mL, 95% CI -35.79 to -12.03, P < 0.0001; three studies). No statistically significant differences were detected for operative time (MD 7.00 min, 95% CI -2.05 to 16.05, P = 0.13), length of hospital stay (MD -0.26 days, 95% CI -1.00 to 0.48, P = 0.49; I2 = 95%) or postoperative complications (OR 0.81, 95% CI 0.51 to 1.31, P = 0.40). Subgroup analyses by indication showed no significant interaction for any outcome (P for subgroup difference: surgical success 0.97, operative time 0.59, complications 0.98); the confidence interval for the ureteropelvic junction obstruction subgroup was wide because only two studies contributed data. Available retrospective comparative evidence suggests that preoperative ureteral rest is associated with higher surgical success after robot-assisted upper urinary tract reconstruction and with a small reduction in estimated blood loss. No clear association was observed with operative time, length of stay or postoperative complications. Because the available evidence is limited to a small number of retrospective studies with heterogeneous indications, definitions and reconstructive techniques, these findings should be considered hypothesis-generating. Current data are insufficient to establish whether the effect differs between acquired ureteral strictures and ureteropelvic junction obstruction.</p>","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208105","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}

This review followed PRISMA guidelines and was registered in PROSPERO (CRD42025643211). A systematic search of PubMed, Embase, and Scopus was conducted through October 2025.

Patient willingness may limit adoption, and to our knowledge no study has measured willingness across defined levels of autonomy while holding performance constant. To estimate the willingness of Jordanian medical students to undergo high-autonomy robotic surgery with immediate surgeon oversight and to quantify how willingness changes as autonomy increases. We conducted a national, multicenter, cross-sectional online survey of a convenience sample of undergraduate medical students at eight Jordanian medical schools between 31 August and 17 September 2026. After a standardized vignette, students rated their willingness to undergo their own operation on a five-point scale under five arrangements, from surgeon-controlled robotic surgery (stage 1) to artificial intelligence (AI) operating with no surgeon in the room and none immediately available (stage 5), with regulatory approval and outcome equivalence held constant. The prespecified primary endpoint was willingness at stage 4 (the AI performs the whole operation while a surgeon in the room can take over); the gradient across stages was a prespecified secondary analysis. Cumulative link mixed models accounted for repeated ratings. Among five hundred seventy-four students (59.6% female), 39.7% (95% CI 35.8 to 43.8) reported willingness at stage 4. The proportion willing fell from 76.0% at stage 1 and 77.7% at stage 2 to 47.2% at stage 3 and 18.6% at stage 5 (odds ratio per stage 0.40, 95% CI 0.37 to 0.42). The largest declines followed AI performance of surgical steps (-30.5% points, 95% CI -35.0 to -25.8) and loss of immediate surgeon presence and rescue capability (-21.1 points, 95% CI -25.0 to -17.0). Trust in autonomous systems showed an association with willingness (adjusted odds ratio per SD 2.75, 95% CI 2.14 to 3.54), whereas surgical career intention showed none. The direction of each decline persisted across analyses of university representation and response quality, although the gradient was steeper among higher-quality respondents; stage 4 willingness ranged from 34.9% to 41.7%. Among these Jordanian medical students, willingness declined in steps rather than along a smooth curve, falling most when the machine began to act and when a surgeon was no longer immediately present or able to intervene. A supervised, stepwise introduction of surgical autonomy, with a surgeon able to intervene, would match their stated preferences; the views of patients remain untested.</p>","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149197130","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 describe our ten-year experience with dHAM as a nerve wrap.

Deep learning tracked the right-hand instrument across 300,000 frames. In four operative phases (bowel mobilization to tumor resection), we computed working-tip kinematics (speed, path length, direction reversals), the tip's position in the surgeon's view, and the camera-instrument distance, reconstructed using the 8-mm shaft as a size reference. Distance stability was expressed as the standard deviation (SD) of the four phase medians (phase-to-phase distance SD). Console-time associations in novices were assessed by Spearman correlation and logistic regression adjusted for R.E.N.A.L. score and body mass index. The expert moved the working tip faster, with fewer direction reversals, more consistent tip placement in the view, and a more stable camera-instrument distance across phases (phase-to-phase SD 5.5 vs. 7.8 mm, P < 0.001).
