Comparison of robotic-assisted and three-dimensional retro-laparoscopic partial nephrectomy in treatment of kidney tumor / 肿瘤研究与临床

ABSTRACT

Objective To compare the safety, efficacy, intraoperative and postoperative outcomes between retro-laparoscopic partial nephrectomy with robotic-assisted laparoscopic (RA-RLPN) and three-dimensional laparoscopic systems(3D-RLPN).Methods Between May 2017 and November 2017,53 patients with cT1-staged renal mass underwent RLPN with two different systems in the First Hospital of Shanxi Medical University. Twenty-eight patients underwent RA-RLPN and twenty-five patients underwent 3D-RLPN. The safety, efficacy, intraoperative and postoperative outcomes were retrospectively analyzed between the two groups. Results All the operations were technically successful. Mean operating room time [(82±18) min vs. (105±5)min,t=4.958,P <0.001)],mean renal artery clamping time[(14.6±2.9)min vs. (18.4±3.5) min,t =5.616, P < 0.001] and postoperative hospitalization [(6.6±1.4) d vs. (7.2±1.5) d, t=2.647, P = 0.021] in RA-RLPN group were shorter than those in 3D-RLPN group. The estimated blood loss was reduced in RA-RLPN group compared with 3D-RLPN group [(60±20) ml vs. (76±24) ml, t= 2.958, P = 0.012]. The postoperative hospital stay in RA-RLPN group was shorter than that in 3D-RLPN group[(6.6±1.4) d vs. (7.2± 1.5) d, t= 2.647, P = 0.021)]. There were no significant differences in the postoperative complications and positive pathological margin incidence between the two groups(both P >0.05).Conclusions RA-RLPN, as a promising surgical technique, is a feasible and safe procedure associated with better intraoperative parameters and short-term effect.It is worthy of clinical application.
