| Background and purpose: About 95% of renal tumors are malignant tumors,most of which are renal cell carcinoma(RCC).RCC is a malignant tumor originating from renal parenchyma and tubular epithelial cells.The specific pathogenesis of RCC has not been clarified yet,but it is closely related to smoking,obesity and hypertension.With the progress of medical technology and people’s increasing attention to health problems,the incidence of early renal tumor(T1N0M0)is increasing year by year.Because its are sensitive to chemotherapy and radiotherapy,surgery is the only cure kidney cancer treatment and conventional laparoscopic resection should be clip renal artery in order to achieve in clear view,but this often takes kidney ischemia-reperfusion injury and suture the wound,so to seek a kind of intraoperative don’t need clip renal artery,no suture surgical methods become the research focus.In recent years,all kinds of new type of laser in the treatment of renal tumor field application,and achieved good results,this topic dragon laser partial nephrectomy for laparoscopic and conventional laparoscopic partial nephrectomy under two kinds of surgical operation time,kidney ischemia time,estimated blood loss and other comprehensive factors,in order to early renal tumor dragon laser partial nephrectomy with clinical data.Method: Twenty-seven patients with T1 NOMO stage renal tumor admitted to the Department of Urology,Huaihua First People’s Hospital from April 2017 to December2020 were retrospectively analyzed.According to different intraoperative energy platform,they were divided into Long Laser group and Leng Dao group.The preoperative,intraoperative and postoperative clinical data of the two groups were statistically summarized.Observation indexes included age,gender,diameter of mass,growth site,operation time,estimated blood loss,renal ischemia time,hemoglobin,postoperative hospital stay,etc.And the two groups of data for statistical analysis,the results.Results :(1)There were no significant differences in age,sex,tumor size,site,preoperative serum creatinine,preoperative hemoglobin and R.E.N.A.L scores between the Longliangyan group and the Lengdao group(P > 0.05).(2)There were no significant differences in postoperative hemoglobin,postoperative creatinine,postoperative hospital stay and estimated blood loss between the two groups(P > 0.05).Preoperative and postoperative creatinine difference and preoperative and postoperative hemoglobin difference: there was no statistical difference between the Long laser group and the Lengknife group(P BBB 0 0.05).(3)The operative time and renal ischemia time of the two groups: the dragon laser group was lower than the cold knife group,and the difference was statistically significant(P < 0.05).Conclusion: Dragon laser under laparoscopic partial nephrectomy with conventional laparoscopic partial nephrectomy slightly with the recent oncology effect,in the aspect of operation time,renal ischemia time laparoscopic dragon laser partial nephrectomy is superior to the conventional laparoscopic partial nephrectomy,laparoscopic partial nephrectomy for laser dragon satisfy conditions limitations of early renal tumors is a safe and feasible. |
