The Clinical Study About The Launch Of Nephron-Sparing Surgery In Renal Carcinoma Patients Of T_1b Term

Objective: To evaluate the short-term and the long-term effects of the launch of nephron-sparing surgery in the renal carcinoma patients of T1 b term.Methods: Taking the clinical method of retrospective analysis,there were 279 cases patients intake the study according to the election criteria and exclusion criteria,and were divided into control group and observation group according to the size of tumor.There were 87 cases renal carcinoma patients of T1 b term in the observation group whose size of tumor was from 4cm to 7cm.And there were 192 cases renal carcinoma patients of T1 a term in the control group whose size of tumor was less than or equal to 4cm.Then we compared the time of operation,the amount of bleeding during operation,the serum creatinine level of postoperative,the occurrence rate of postoperative complications,the occurrence rate of CKD of 3 times follow-up of postoperative,the total survival rate,and the recurrence rate between the two groups.Results: To compare the time of operation,it of the observation group was(132.60±24.01)min,and it of the control group was(92.51±22.90)min.The difference between the two groups has statistical significance(P<0.05).To compare the amount of bleeding during operation,it of the observation group was(150.91±39.20)ml,and it of control group was(114.82±36.71)ml.The difference between the two groups has statistical significance(P<0.05).To compare the serum creatinine level of postoperative,it of the observation group was(97.12±19.6)?mol/L,and it of control group was(92.10±20.57)?mol/L.The difference between the two groups hasn't statistical significance(P>0.05),and the mean values of the two groups were all within the normal value.To compare the occurrence rate of postoperative complications,it of the observation group was 5.75%,and it of control group was 2.08%.The difference between the two groups hasn't statistical significance(P>0.05),and the occurrence rate of postoperative complications of observation group was equivalent to the control group.To compare the occurrence rate of CKD of postoperative,them of follow-up 3 months,one year,and two years of the observation group were 1.15%,2.47%,and 2.47% respectively,and them were 1.04%,2.12%,and 2.75% respectively.The difference between the two groups hasn't statistical significance(P>0.05),the occurrence rate of CKD of 3 times follow-up of postoperative of the observation group were equivalent to the control group.To compare the total survival rate,it of the observation group was 93.10%,and it of the control group was 95.31%.The difference between the two groups hasn't statistical significance(P>0.05),the total survival rate of the observation group were equivalent to the control group.To compare the recurrence rate,it of the observation group was 8.05%,and it of the control group was 5.21%.The difference between the two groups hasn't statistical significance(P>0.05),the recurrence rate of the observation group were equivalent to the control group.Conclusions: Compared with the renal carcinoma patients of T1 a term who were treated by NSS,the effects and safety of short term and long term of the patients of T1 b term who were treated by NSS were equal to them,which declared that the renal carcinoma patients of T1 b term treated by NSS was feasible.
