Abstract
Background: To evaluate the application of R.E.N.A.L. nephrometry score (RNS) in laparoscopic partial nephrectomy (LPN) with zero ischemia and sutureless surgery, and to explore the efficacy and safety of zero ischemia and seamless LPN in the treatment of renal cell carcinoma.Methods: The clinical data of 67 patients with renal cell carcinoma treated by LPN in the affiliated Hospital of Guizhou Medical University from January 2016 to July 2020 were analyzed retrospectively. The patients were divided into renal artery occlusion group (n=31) and non-occlusion group (n=36). All cases were divided according to their RNS (low, moderate, and high), and the perioperative condition, postoperative complications, postoperative recovery and changes of renal function in the two groups were analyzed.Results: According to the RNS, all cases were classified in low-complex. Both groups successfully completed the operation without operative complications. Compared with the renal artery occlusion group, the non-occlusion group had a shorter operation time (35.51±20.48 min), shorter hospital stay (6.72±4.39 d), and no significant difference in intraoperative blood loss(50.39±30.19 ml). During the 6-month follow-up, the creatinine value of the renal function in the non-occlusion group (78.47±10.98μmol/L) was lower than that in the occlusion group(98.21±8.06μmol/L).Conclusion: Zero-ischemia sutureless LPN technique can effectively reduce the time of ischemia and avoid renal ischemia-reperfusion injury. This surgical technique may be a feasible surgical method for the treatment of low RNS renal cell carcinoma.
