Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Subjects were given informed consent before enrolling the study and randomized into two groups. Intravenous (IV) cannula (18-20G) with Ringer Lactate fluid, non-invasive blood pressure monitor, electrocardiogram (ECG), ICON® monitor, hemodynamic monitor and pulse-oxymetry were set on the subjects in the operation room. Epidural catheter was inserted (4 cm depth inside the epidural space) with 2 mg IV midazolam and 1 mcg/kg IV fentanyl as premedication. The catheter insertion was confirmed with vacuum aspiration and negative test-dose. General anesthesia induction was done by fentanyl 4 mcg/kg, propofol 1-2 mg/kg, and rocuronium 0,5 mg/kg. Maintenance was done by sevoflurane 1 minimum alveolar concentration (MAC), fentanyl and rocuronium with bupivacaine bolus 6ml every 90 minutes. Surgery starts with intraoperative epidural regimen. Patient were position lumbotomy laterally, CO2 gas insufflated during the instalment of laparoscopy probe until it reaches 10- 12 mmHg pressure. Laparoscopy targeted the pneumoperitoneum pressure until 8- 10 mmHg or 12- 14 mmHg depends on subject randomization. Surgery duration, blood pressure, heart rate, respiratory rate, oxygen saturation (SpO2) were recorded. During surgery, blood sample for interleukin (IL)-6, Syndecan-, sVGEF-R2, occludin and KIM-1 urine were taken on 1st hour, 2nd hour and 24th hour after baseline. The measurement of renal artery and kidney lobe artery that undergo nephrectomy, will be measured by convex probe 3.5-5 megahertz (MHz) ultrasonography (USG) Logic 7-GE or Sonosite. The measurement of RI was done before CO2 gas insufflated as baseline on 1st hour, 2nd hour on laparoscopy and 24 hour after baseline. Patient were extubated until fully conscious and can follow command verbally. Patient will be transported in recovery room post operation. Data was analyzed using SPSS (Statistical Package for Social Scientist), for parametric unpaired data is using unpaired T-test or One way ANOVA test, ffor unpaired non parametric data using Mann Whitney or Kruskal Wallis. Non Parametric continuous data using Wicoxon's signed rank test or Friedman Test. Categorical data using Chi-square. For numerical data more than 1 measurement will be analysed using Comparative General Linear Model. Data normality was tested by Kolmogorov-Smirnov test. Significant value is p<0.05.
