Abstract:
Objective To analyze the effect of endophytic renal tumor growth characteristic on the short-term outcomes of robot-assisted laparoscopic partial nephrectomy (RALPN).Methods From March 2015 to October 2016,23 RALPN cases of endophytic renal masses and 68 RALPN cases of intermediate and exophytic renal tumors were retrospectively analyzed.There were no significant differences in age,gender,tumor side,history of abdominal surgery,benign and malignant cases of the two groups of patients (P ＞ 0.05).Patients with a completely endophytic mass had smaller tumors [(2.4 ± 0.5) cm vs.(3.9 ± 1.1) cm],and higher overall R.E.N.A.L.score (P ＜ 0.05).The differences of perioperative period and postoperative follow-up results were analyzed.Results All 91 RALPN cases were successfully done without conversion to open or radical nephrectomy.There were no significant differences in intraoperative blood loss,postoperative Hb decrease,intraoperative and postoperative blood transfusion rate,hospital days,positive tumor margins,and the incidence of Clavien-Dindo grade Ⅲ or above in the two groups (P ＞ 0.05).The endophytic group showed longer operative time [(95.6 ± 19.4) min vs.(75.3 ± 16.9) min],and longer renal warm ischemia [(25.2 ±5.4)min vs.(17.6 ±7.0)min].In the postoperative follow-up of 3 months to 22 months,all patients got disease-free survival.Conclusions RALPN for completely intraparenchymal renal tumors can be safely and effectively performed in experienced institutes.However,the long-term period of follow-up is still missing.
