| ObjectiveDiscuss the clinical significance of R.E.N.A.L.kidney neoplasms marking system for the patients with bilateral kidney cancer.MethodsSelected 7 patients with bilateral kidney cancer received and cured by The First Affiliated Hospital of Zhengzhou University from Feb.2013 to Aug.2017,and conducted retrospective analysis,then conducted marking with R.E.N.A.L.system,and analyzed the relationship between the R.E.N.A.L.kidney neoplasms marking and selection of operation mode,cold-ischemia time,preoperative bleeding,length of stay after operation,complications in perioperative period and postoperative renal function.Results10 cases were treated with laparoscopic nephron preservation(LPN).There were 4 cases of laparoscopic radical nephrectomy(LRN),and 6 cases,6 cases and 2 cases of low-,middle-,and highly-complex tumors in the RENAL kidney tumor scoring system.The LPNs were 6 cases respectively.4 cases and 0 cases;the mean value of RENAL scores in LPN(5.8±1.9)groupand LRN group(8.1±1.7)was statistically significant(P<0.05);the selection of RENAL renal tumor scoring system and LPN method was significant.Correlation(?2 = 30.9,P < 0.05),low and most moderately complex tumors were suitable for LPN.ConclusionR.E.N.A.L.nephrometry score is a comprehensive scoring system to evaluate the anatomical characteristics of kidney neoplasms,which can conduct relatively good evaluation for the selection of operation mode,complexity of operation and surgical risk of patients with bilateral kidney cancer. |
