Comparison Of Robot-assisted Retroperitoneal Laparoscopic And Conventional Retroperitoneal Laparoscopic Partial Nephrectomy

Objective: To retrospectively analyze the clinical results of 35 patients with renal tumors underwent robot-assisted retroperitoneal laparoscopic partial nephrectomy and 35 patients underwent conventional retroperitoneal laparoscopic partial nephrectomy in the Department of Urology,First Affiliated Hospital of China Medical University from October 2017 to December 2018.To compare the efficacy and safety of robot-assisted retroperitoneal laparoscopic partial nephrectomy(RARPN)and conventional retroperitoneal laparoscopic partial nephrectomy(LPN).Methods:Retrospective analysis of clinical data of 70 patients with renal cell carcinoma underwent RARPN and LPN in our hospital from October 2017 to December 2018.The observation group consisted of 35 patients who underwent RARPN,and the control group received 35 patients who underwent LPN.The age,gender,tumor side,tumor diameter,preoperative R.E.N.A.L scores,operative time,warm ischemia time,postoperative drainage,postoperative activity time,postoperative hospital stay,perioperative complications,and recurrence and metastasis were compared.All patients were followed up for 4-14 months.Results:RARPN and LPN in 35 cases,a total of 70 cases.RARPN group of 20 males,15 females,13 cases of left tumor,22 cases of right side;21 males in LPN group,14 females,18 cases on the left side of the tumor,17 cases on the right side.The mean ages of the RARPN group and the LPN group were 52.4±13.4 years and 53.8±12.6 years;the tumor diameters were 2.9±0.91 cm and 2.8±0.98cm;the preoperative R.E.N.A.L.scores were6.5±1.4 and 6.3±1.3.After comparison,there was no significant difference in gender,tumor side,age,tumor diameter and preoperative R.E.N.A.L.scores between the two groups(p>0.05).The operation time was 99.2±20.7min and 106.1±35.0min;the warm ischemia time was 20.5±4.9min and 24.2±6.0min;the postoperative drainage volume was 209.0±120.1ml and 116.7±123.9ml;postoperative activity time was 3.6±0.7d and5.9±0.9d;the postoperative hospital stay was 6.6±1.6d and 7.3±1.7d.The warm ischemia time,postoperative activity time and postoperative drainage volume of the two groups were statistically significant(p<0.05),the operation time and the postoperative hospital stay of the two groups was no significant difference(p>0.05).The pathological findings of the two groups were negative,and there were no perioperative complications in the two groups;no recurrence and metastasis were found during the two follow-up periods.Conclusions:RARPN has a shorter warm ischemia time and postoperative activity time than LPN,and is a safe and effective minimally invasive surgery.With the popularity of robots and the accumulation of surgeon experience,RARPN will have a good clinical application prospect.
