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.

602 Background: To compare and analyze surgical, oncological and functional outcomes of transperitoneal (TRPN) and retroperitoneal robotic partial nephrectomy (RRPN). Methods: Out of 566 consecutive patients who underwent RAPN by a single surgeon from December 2008 to July 2017, this study included 523 patients (TRPN 310, RRPN 213) who evaluated preoperative and 1-year postoperative estimated glomerular filtration rate (eGFR). Our primary endpoint was to compare the perioperative and postoperative outcomes of both approaches by the measure of Pentafecta (negative surgical margin, no 30-day complication, warm ischemic time (WIT) ≤25 minutes, return of estimated glomerular filtration rate (eGFR) to > 90% from baseline and no upstaging of chronic kidney disease). Secondary endpoint was to find the factors associated with Pentafecta by multivariate regression analysis. Results: No significant difference was found in terms of age, BMI, laterality, history of hypertension or diabetes, ASA grade, tumor size and RENAL nephrometry score. These outcomes were lower in the RRPN group: operative time [median (IQR) 244 (202-295) vs. 273 (230-314); p < 0.001], WIT [median (IQR) 19 (15-25) vs. 21 (16-27); p < 0.008] and estimated blood loss (EBL) [median (IQR) 100 (60-200) vs. 150 (100-200); p < 0.003]. Hospital stay, baseline eGFR, 1-year postoperative eGFR, the rate of Pentafecta achievement, recurrence and complications were not different. The rate of WIT ≤ 25 minutes was solely significantly different (TRPN 69.7% vs. RRPN 77.9%, p = 0.045) in the Pentafecta criteria. Multivariate analysis revealed tumor size [OR (95% CI) 0.641 (0.536-0.767), p < 0.001) and hospital stays (OR 0.639, p < 0.001) as predictive for lack of Pentafecta. Conclusions: RRPN demonstrated less operative time, WIT and EBL than TPRN. Pentafecta achievements were equivalent in both approaches. Tumor size and hospital stays were found as predictive factors of Pentafecta.

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 The ability of nephrometry scoring systems, including the radius, exophytic/endophytic, nearness to collecting system or sinus, anterior/posterior, and location relative to polar lines (R.E.N.A.L.), to predict loss of renal function after robotic partial nephrectomy (RPN) is still controversial. Therefore, we verified which combination of factors from nephrometry scoring systems, including tumor volume, was the most significant predictor of postoperative renal function. Patients who underwent RPN for cT1 renal tumors in our hospital were reviewed retrospectively (n=163). The preoperative clinical data (estimated glomerular filtration rate [eGFR], comorbidities, and nephrometry scoring systems including R.E.N.A.L.) and perioperative outcomes were evaluated. We also calculated the tumor volume using the equation applied to an ellipsoid by three-dimensional computed tomography. The primary outcome was reduced eGFR, which was defined as an eGFR reduction of ≥20% from baseline to 6 months after RPN. Multivariate logistic regression analyses were used to evaluate the relationships between preoperative variables and reduced eGFR. Of 163 patients, 24 (14.7%) had reduced eGFR. Multivariate analyses indicated that tumor volume (cutoff value≥14.11 cm3, indicating a sphere with a diameter≥approximately 3 cm) and tumor crossing of the axial renal midline were independent factors for reduced eGFR (odds ratio [OR], 4.57; P=0.003 and OR, 3.21; P=0.034, respectively). Our classification system using these two factors showed a higher area under the receiver operating characteristic curve (AUC) than previous nephrometry scoring systems (AUC=0.786 vs. 0.653–0.719), and it may provide preoperative information for counseling patients about renal function after RPN.

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.

Background and objectives: Microwave thermal ablation (MWT) is one of the treatment options for kidney cancer. However, for patients over 70 years old the safety and oncological efficacy of this treatment is still controversial. The goal of this study was to compare MWT with open partial nephrectomy (OPN) and to find out whether MWT is preferable in maintaining patient renal function and reducing the risk of postoperative complications. Materials and Methods: Depending on the treatment choice, all patients were divided into two groups: an MWT group and an open kidney resection (OPN) group. Data have been retrospectively collected for 7 years, starting with January 2012 up to January 2019. A total number of 33 patients with exophytic, single small renal masses were treated with either OPN (n = 18) or MWT (n = 15). All patients had histologically proven T1 kidney cancer. MWT was performed for patients who refused to have OPN or in those cases where the collecting system, renal calyx, and great vessels were free from tumor margins of more than 1 cm. Results: In the MWT group a median (IQR) patients’ age was 75 years (71–79) years, in the OPN group—71.5 (70–75) years, p = 0.005. A median (IQR) Charleston comorbidity index in the MWT group was 7.5 (5–10) and in the same way in the OPN group it was 5.22 (5–6), p = 0.005. A median (IQR) estimated glomerular filtration rate (eGFR) before surgery was higher in the MWT group 59.9 (49.5–73.8) mL/min/1.73 m2 vs. 46.2 (42.7–65.8) mL/min/1.73 m2 in the OPN group, p = 0.12. Three days following the surgery a median (IQR) eGFR was 56.45 (46.6–71.9) in MWT group mL/min/1.73 m2 vs. 43.45 (38.3–65) mL/min/1.73 m2) in the OPN group, p = 0.30. A median (IQR) of primary hemoglobin level was lower in the MWT group compared with the OPN group (134.5 (124–140) g/L vs. 125 (108–138) g/L), p = 0.41. However, after the surgery a median (IQR) lower hemoglobin level was detected in the OPN group (123.5 (111–134) g/L vs. 126 (112–135)), p = 0.53. The median (IQR) duration of the procedure in MWT group was shorter compared with the OPN group (26 (25–30) min vs. 67.5 (55–90) min), p < 0.0001. A median (IQR) hospitalization time was shorter in MWT group (3 (2–3) days vs. 89 (7–11.5) days), p < 0.0001. Pain by the visual analogue scale (VAS) scale the first day after surgery was significantly lower—median (IQR) in the MWT group was 2 (1–3) vs. 4 (3–6)), p = 0.008. Treatment failure rate was numerically higher in MWT (1/15 vs. 0/18, p = 0.56). Conclusions: Pain level on the next day after surgery, mean number of hospitalization and operation time were significantly lower in the MWT group than in the OPN group. The blood loss estimated glomerular filtration rate and oncologic data between the two groups was not statistically significant.
