| Objective:To compare the safety and effectiveness of robot-assisted partial nephrectomy(RAPN)versus laparoscopic partial nephrectomy(LPN)in the treatment of central renal angiomyolipoma(RAML).Materials and methods:The clinical data of 103 patients who were treated with either RAPN or LPN for central RAML between January 2017 and June 2022 collected from our hospital were retrospectively analyzed.Propensity scores were matched according to sex,age,side of treated RAML,body mass index,symptoms,diameter of tumor,location of tumor distribution,R.E.N.A.L score,preoperative hemoglobin,preoperative serum creatinine,preoperative estimated glomerular filtration rate,chronic disease,previous abdominal surgery,preoperative selective arterial embolization,American society of anesthesiologists scale,duration of follow-up,and after 1:1 matching,perioperative and prognostic related data of the two groups were compared.Results:A total of 57 patients underwent RAPN,and 46 patients underwent LPN.Before matching,there were more complex RAML in the RAPN group,and R.E.N.A.L scores differed between the two groups(10 versus 9,P<0.001).After matching,27 patients in each group,the median warm ischemic time(WIT)was 21.5 min in the RAPN group,shorter than 28 min in the LPN group(P=0.034),as well as the median time of the first off-bed activity after surgery(1 day versus 2 days,P<0.001).The other indicators were not significantly different between the groups.Conclusion:For central RAML,both RAPN and LPN were safe and feasible surgical treatments,but RAPN might be associated with shorter warm ischemia time and earlier postoperative off-bed activities. |
