Objective To explore the feasibility of laparoscopic partial nephrectomy(LPN) in the treatment of renal hilar tumors. Methods Clinical data of 290 patients undergoing laparoscopic partial nephrectomy from January 2013 to August 2019 were retrospectively analyzed, including 27 patients with renal hilar tumors and 263 patients with non-hilar renal tumors. Perioperative data and follow-up results were compared between the two groups. Results Tumor size in Group A is smaller(2.97±0.88 vs

There was no significant difference between the two groups in intraoperative ultrasound rate, collection system repair rate, drainage time,postoperative hospital stay, and eGFR changes (p>0.05).The median follow-up period was 40 months. One patient with postoperative pathologic report of angiomyolipoma was found tumor recurrence and was currently undergoing regular reexamination. Conclusion Three-dimensional laparoscopic partial nephrectomy for renal hilar tumors is safe and feasible after detailed preoperative evaluation of the tumor and selection of appropriate surgical strategies.
