Background: The objective of this study was to evaluate our experience with robot-assisted partial nephrectomy (RAPN) in comparison with conventional open partial nephrectomy (OPN). Patients and Methods: This study included 37 and 50 patients undergoing OPN and RAPN for small renal masses, respectively. A single surgeon performed RAPN for all 50 cases using the da Vinci Xi. Trifecta was defined as satisfying all of the following 3 criteria: ischemic time of ≤ 25 minutes, negative surgical margin and no major postoperative complications. Results: After adjusting patient variables by 1:1 propensity-score matching, 37 patients were included in each group, and no significant differences in major clinicopathological characteristics were noted between these 2 groups. RAPN was significantly superior to OPN with respect to operative time, estimated blood loss and postoperative length of hospital stay. The rate of trifecta achievement was significantly higher in the RAPN group than in the OPN group (91.9 vs. 62.2%). Furthermore, the operative procedure and R.E.N.A.L. nephrometry score were found to be independently associated with trifecta outcome by multivariate analysis of the entire cohort. Conclusions: Although this is our early experience with 50 initial cases, RAPN using the da Vinci Xi resulted in more favorable perioperative outcomes than OPN.

Purpose.The surgical expertise to perform robotic partial nephrectomy is heavily dependent on technology. The Da Vinci Xi (XI) is the latest robotic surgical platform with significant advancements compared to its predecessor. We describe our operative technique and experience with the XI system for robotic partial nephrectomy (RPN).Materials and Methods.Patients with clinical T1 renal masses were offered RPN with the XI. We used laser targeting, autopositioning, and a novel “in-line” port placement to perform RPN.Results.15 patients underwent RPN with the XI. There were no intraoperative complications and no operative conversions. Mean console time was 101.3 minutes (range 44–176 minutes). Mean ischemia time was 17.5 minutes and estimated blood loss was 120 mLs. 12 of 15 patients had renal cell carcinoma. Two patients had oncocytoma and one had benign cystic disease. All patients had negative surgical margins and pathologic T1 disease. Two postoperative complications were encountered, including one patient who developed a pseudoaneurysm and one readmitted for presumed urinary tract infection.Conclusions.RPN with the XI system can be safely performed. Combining our surgical technique with the technological advancements on the XI offers patients acceptable pathologic and perioperative outcomes.

Introduction: We investigate the clinical significance of the R.E.N.A.L. nephrometry score for renal neoplasm following open partial nephrectomy (PN) under cold ischemia.Methods: A retrospective analysis was conducted using clinical data of 98 consecutive patients with clear cell renal cell carcinoma who underwent open PN by a single surgeon from December 2000 to September 2012. Tumour complexity was stratified into 3 categories: low (4-6), moderate (7-9) and high (10-12) complexity. Perioperative outcomes, such as complications, cold ischemic time, estimated blood loss and renal function, were analyzed according to the complexity by NS. Complications were stratified using the Clavien-Dindo classification system.Results: Tumour complexity according to nephrometry score was assessed as low in 16 (16.3%), moderate in 48 (49.0%) and high in 34 (34.7%). The median cold ischemic time did not differ significantly among the 3 groups (36.0 minutes in low-, 40 minutes in moderate- and 43 minutes in the high-complexity group, p = 0.421). Total complications did not differ significantly (2 (2.0%) in low, 4 (4.1%) in moderate and 4 (4.1%) in high, p = 0.984). Each Grade 3 complication occurred in the moderate (urine leakage) and high groups (lymphocele). Postoperative renal functional outcomes were similar among the groups (p = 0.729). Only mean estimated blood loss was significantly different with nephrometry score (p = 0.049).Conclusions: The nephrometry score, as used in an open PN series under cold ischemia, was not significantly associated with perioperative outcomes (i.e., ischemia time, complications, renal functional preservation).

Abstract BackgroundTo compare the perioperative outcomes of Robotic partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN). MethodsWe searched PubMed, EMBASE and the Cochrane Central Register for studies from 2000 to 2020 to evaluate the perioperative outcomes RPN and LPN in patients with a RENALnephrometry score≥7. We used RevMan 5.2 to pool the data. ResultsSeven studies were acquired in our study. No significant differences were found in the estimated blood loss (WMD: WMD: 34.49, 95% CI -75.16-144.14, p=0.54), hospital stay (WMD: -0.59 95% CI -1.24–0.06, p=0.07), operating time (WMD: -22.45, 95%CI: -35.06 to-9.85, ), postive surgical margin (OR: 0.85, 95% CI 0.65–1.11, p =0.23) and transfusion (OR: 0.72, 95% CI 0.48–1.08, p =0.11).between the two groups. RPN get better outcomes in postoperative renal function (WMD: 3.32, 95% CI 0.73–5.91, p=0.01), warm ischenia time (WMD: -6.96, 95% CI -7.30–-6.62, p <0.0001), conversion( OR: 0.34, 95%CI: 0.17 to 0.66, p=0.002) and intraoperative complication (OR: 0.52, 95% CI 0.28–0.97, p=0.04).ConclusionRPN could get better perioerative clinical outcomes than LPN for treatment of Complex Renal Tumors( with a RENALnephrometry score≥7).

Purpose. Robotic surgery for colorectal cancer is an emerging technique. Potential benefits as compared with the conventional laparoscopic surgery have been demonstrated. However, experience with the previous da Vinci Si robotic system revealed several unsolved problems. The novel features of the new da Vinci Xi increase operational flexibility and maneuverability and are expected to facilitate the performance of multiquadrant surgery. Methods. Between December 2011 and May 2015, 120 patients with colon or rectal cancer were operated on using the Si robotic system (the Si group). Between May 2015 and October 2017, 60 more patients with colon or rectal cancer were operated on using the Xi robotic system (the Xi group). The clinicopathological characteristics and perioperative outcomes of these 2 groups of patients were compared. Results. The 2 groups of patients were comparable with regard to baseline clinical characteristics, types of resection performed, and the proportion of patients undergoing neoadjuvant chemoradiation therapy. The statuses of resection margin, the numbers of lymph nodes harvested, and the rates of postoperative complications were also similar between the 2 groups. Nevertheless, a lower rate of diverting ileostomy, a shorter operation time, less estimated blood loss, and a faster postoperative recovery was observed in the Xi group. Conclusions. Colorectal cancer surgery using the Xi robotic system was associated with improved perioperative outcomes. These benefits may be attributed to its improved, more user-friendly design.

<p><strong>Introduction: </strong>We sought to evaluate the association of obesity with surgical outcomes of robotic partial nephrectomy (RPN) using a large, multicentre database.<strong> </strong></p><p><strong>Methods: </strong>We identified 1836 patients who underwent RPN from five academic centres from 2006-2014.  A total of 806 patients were obese (body mass index [BMI] ≥30 kg/m<sup>2</sup>). Patient characteristics and outcomes were compared between obese and non-obese patients. Multivariable analysis was used to assess the association of obesity on RPN outcomes.</p><p><strong>Results: </strong>A total of 806 (44%) patients were obese with median BMI of 33.8kg/m<sup>2</sup>. Compared to non-obese patients, obese patients had greater median tumour size (2.9 vs. 2.5 cm, p&lt;0.001), mean RENAL nephrometry score (7.3 vs. 7.1, p = 0.04), median operating time (176 vs. 165 min, p=0.002), and median estimated blood loss (EBL, 150 vs. 100 ml, p=0.002), but no difference in complications. Obesity was not an independent predictor of operative time or EBL on regression analysis. Among obese patients, males had a greater EBL (150 vs. 100 ml, p&lt;0.001), operative time (180 vs. 166 min, p&lt;0.001) and warm ischemia time (WIT, 20 vs. 18, p=0.001) and male sex was an independent predictor of these outcomes on regression analysis.</p><p><strong>Conclusion: </strong>In this large, multicentre study on RPN, obesity was not associated with increased complications and was not an independent predictor of operating time or blood loss.  However, in obese patients, male gender was an independent predictor of greater EBL, operative time, and WIT.  Our results indicate that obesity alone should not preclude consideration for RPN.<strong></strong></p>

701 Background: This study was designed to investigate the parameters that predict the short term and long term renal function after opened partial nephrectomy (OPN) and robot-assisted partial nephrectomy (RPN). Methods: Medical records of 896 patients who underwent OPN and RPN between Feb 2004 to Apr 2017 at our institution were retrospectively reviewed. The propensity scores matching between of OPN and RPN group were performed with a ratio of 1:1. Postoperative outcomes were compared and multivariate logistic regression was performed to identify the parameters influencing acute kidney injury (AKI) and chronic kidney disease (CKD) progression. Results: No significant differences of preoperative characteristics were observed between two study groups after propensity score matching. RPN was significantly associated with longer warm ischemic time (WIT) (p < 0.001); yet, estimated blood loss (EBL), positive surgical margin (PSM) rate, major postoperative complication and CKD progression were significantly lower in RPN group (p values were < 0.001; 0.033; < 0.001; < 0.001 and 0.005 respectively). Multivariate analysis exhibited RPN is more favorable than OPN in terms of preserving renal function. Patients with a higher baseline estimated glomerular filtration rate (eGFR) were significantly associated with greater risk of AKI (OR = 1.036; 95% CI of OR 1.021-1.052; p < 0.001), but reduced risk of CKD progression (OR = 0.975; 95% CI of OR 0.955-0.994; p = 0.011). Other independent predictors of CKD progression included WIT (p = 0.025), age (p = 0.035), higher BMI (0.041) and diabetes mellitus history (p = 0.035). Conclusions: Age, BMI, diabetes mellitus history, baseline eGFR and WIT were the independent predictors of CKD progression after PN. RPN is more favorable than OPN for reducing EBL, PSM, major postoperative complication and renal function preservation.

Objective. To report the perioperative outcomes of patients treated with partial nephrectomy by a single surgeon using three surgical modalities—open, laparoscopic, and robotic. Methods. Between August 2006 and February 2012, 106 consecutive patients underwent open partial nephrectomy (OPN) (n=23), laparoscopic partial nephrectomy (LPN) (n=48), and robotic partial nephrectomy (RPN) (n=35) by a single surgeon. Clinical variables, operative parameters, and renal functional outcomes were analyzed. Results. Preoperative patient characteristics were similar except for baseline glomerular filtration rate (GFR), which was highest in the RPN group (P=0.004). Surgery time was longest in the RPN group (244 minutes) and shortest in the OPN group (163 minutes, P<0.0001). Patients who had OPN had the highest incidence of 30-day complications (30%), while the RPN approach had the lowest (14%, P=0.008). Conclusions. When performed by a single surgeon, robotic partial nephrectomy appears to be associated with fewer complications than both open and laparoscopic partial nephrectomy. Kidney function was not affected by surgical approach.

Objective: To evaluate a single surgeon oncological and functional outcomes of laparoscopic partial nephrectomy (LPN) compared to robotic partial nephrectomy (RPN) for pT1a renal tumours. Materials and methods: Between 2006 and 2016, a retrospective review of 42 patients who underwent LPN (n = 20) or RPN (n = 22) by same surgeon was performed. Patients were matched for gender, age, body mass index (BMI), American Society of Anaesthesiologists (ASA) score, tumour side, RENAL and PADUA scores, peri-operative and post-operative outcomes. Results: There was no significant differences between the two groups with respect to patient gender, age, BMI, ASA score, tumours side, RENAL and PADUA scores. Mean operative time for RPN was 176 vs. 227 minutes for LPN (p = 0.001). Warm ischemia time was similar in both groups (p = 0.58). Estimated blood loss (EBL) was higher in the LPN. There was no significant difference with preoperative and postoperative creatinine and percent change in eGFR levels. Only one case in LPN had positive surgical margin. Conclusions: RPN is a developing procedure, and technically feasible and safe for small-size renal tumours. Moreover RPN is a comparable and alternative operation to LPN, providing equivalent oncological and functional outcomes, as well as saving more healthy marginal tissue and easier and faster suturing.
