All clinical variables including tumor nephrometry (PADUA score) and laboratory analyses were recorded. Surgical results and complications, stratified with Clavien system, and pathological data were registered. All significant differences  in OPN versus RAPN group were assessed. Independent predictors of surgical complications were evaluated with multivariate analysis.RESULTS: 198 and 104 patients were enrolled in the OPN and RAPN group, respectively.  As summarized in the table, Charlson comorbility index was significantly higher in RAPN group while clinical tumor diameter and imperative surgical indication were higher in OPN group.Pedicle clamping was used in 48% and 62,5% of OPN and RAPN group, respectively. In RAPN group 1 procedure was converted to open due to vascular lesion. At univariate analysis, there was no significant difference in warm ischemia time, intraoperative complications, postoperative medical complications, delta of serum creatinine, positive surgical margin and benign tumor rates. The operative time resulted significantly higher in RAPN group, while the estimated blood loss, the delta of serum Hemoglobin and the postoperative surgical complications were significantly higher in OPN group. 9,6% of Clavien grade 3-4 surgical complications occurred in OPN group, while 1 in RAPN group (p=0,001). Ureteral stenting for urinary fistula was needed in 4% and 0% in the OPN and RAPN group, respectively (p=0,008). Revision of postoperative bleeding was needed in 2,5% and 1% (p=0,07). At multivariate analysis, the imperative indication and the surgical approach (Open vs Robotic) resulted independently correlated with postoperative surgical complications (RR=3,8; p=0,05 and RR=4,2; p=0,01,respectively).259 Robotic-assisted versus open partial nephrectomy: A prospective multicenter comparison study of perioperative outcomes (AGILE project)Eur Urol Suppl 2013;12;e259Partial nephrectomy OPN RAPN PN patients 198 104 NsMale gender 62% 65.4% NsAge   (years) 63,8  ± 12,4 63 ± 11 NsBMI 27,2 ± 4,9 26,1 ± 4 NsASA score 3 14,6% 14% NsCharlson Index ≥ 2 5,6% 26% 0,04Imperative indications 5,05% 1% 0,07CONCLUSIONS: In our analysis the robotic approach clearly improved the incidence of postoperative complication and the reintervention rate.
