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.

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.

Abstract Background To compare the perioperative outcomes of robotic partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN) for complex renal tumors with a RENAL nephrometry score≥7. Methods We searched PubMed, EMBASE and the Cochrane Central Register for studies from 2000 to 2020 to evaluate the perioperative outcomes of RPN and LPN in patients with a RENAL nephrometry score≥7. We used RevMan 5.2 to pool the data. Results Seven studies were acquired in our study. No significant differences were found in the estimated blood loss (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), positive surgical margin (OR: 0.85; 95% CI: 0.65–1.11; p =0.23), major postoperative complications(OR: 0.90; 95% CI: 0.52–1.54; p=0.69) and transfusion (OR: 0.72; 95% CI: 0.48–1.08; p =0.11) between the groups. RPN showed better outcomes in the operating time (WMD: -22.45; 95% CI: -35.06 to -9.85; p=0.0005), postoperative renal function (WMD: 3.32; 95% CI: 0.73–5.91; p=0.01), warm ischemia time (WMD: -6.96; 95% CI: -7.30–-6.62; p <0.0001), conversion rate to radical nephrectomy (OR: 0.34; 95% CI: 0.17 to 0.66; p=0.002) and intraoperative complications (OR: 0.52; 95% CI: 0.28–0.97; p=0.04).Conclusions RPN showed better perioperative clinical outcomes than LPN for the treatment of complex renal tumors with a RENAL nephrometry 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>

Objectives: To evaluate oncological feasibility and oncological and functional results of retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy (LPN). Patients and methods: Patients with posterior renal masses with low nephrometry score (RENAL ≤ 7) treated who underwent retroperitoneal sutureless zero ischemia.in a single center from January 2016 to November 2017. Clinical, surgical and pathological data were prospectively collected. Complications were reported according to the modified Clavien classification. Results: Retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy was performed on 15 patients. The indication for nephron-sparing surgery was elective in 11 (73%) patients and imperative in 4 (27%). Median RENAL score was 5 (IQR: 5-7), median tumor diameter 25 mm (IQR: 20-35). In 11 cases, the tumor was located polar (85%), and in 2 cases hilar (15%). There were no intraoperative complications. No cases were converted to radical nephrectomy, and in no case parenchyma suture was necessary. Median operative time was 90 min (IQR:40-150), in no case clamping of the renal artery was necessary, median hospital stay was 4 days, median estimated blood loss (EBL) was 310 (180-500) ml. Pathological analysis showed renal cell carcinoma in 11 patients (85%), 9 (60%) staged T1a and 2 (13%) T1b. In 4 (27%) an oncocytoma was found. There were no positive surgical margins. One patient developed a major postoperative complication (postoperative renal bleeding requiring super-selective embolization). Trifecta rate was 93%. Conclusions: Sutureless retroperitoneal zero ischemia LPN for the treatment of low-complexity posterior renal masses showed to be safe and feasible. Longer follow-up and higher numbers of patients are, however, warranted to draw definitive conclusions on functional outcomes.
