Abstract: Laparoscopic partial nephrectomy (LPN) has matured in the treatment of early localized renal carcinoma, but it still has limitations in complex renal tumors. Since the successful implementation of LPN in hilar renal tumors was reported in 2005, with the improvement of surgical techniques, the success rate of kidney-preserving surgery for hilar renal tumors has been increasing continuously. Since 2015, our center has significantly improved the safety and feasibility of surgery by combining various technologies and methods such as preoperative IQQA intelligent 3D and 3D imaging, preoperative scoring, intraoperative suture technology, renal artery occlusion technology and so on. In this paper, preoperative evaluation planning, intraoperative techniques and improvement of difficulties in hilar renal tumor LPN were briefly reviewed.

Key words: renal sinus tumor, laparoscopic partial nephrectomy, individualized surgery
