Related Factors Of Early Renal Function Changes After Laparoscopic Partial Nephrectomy

Objective:Analysis of related factors affecting early renal function after laparoscopic partial nephrectomy in patients with renal tumor.Methods:The clinical data of 63 patients who underwent laparoscopic partial nephrectomy from June 2016 to June 2018 were retrospectively analyzed.Glomerular filtration rate（GFR）of the renal units with tumor from ⁹⁹m Tc-Diethylenetetramine pentaacetic acid(⁹⁹m Tc-DTPA)renal scan was measured preoperatively and 3 months postoperatively.Age,sex,body mass index（BMI）,warm ischemia time（WIT）,operation time,R.E.N.A.L score,pathological type,accompanying diseases（hypertension,diabetes）,intraoperative blood loss,tumor location and serum creatinine were collected.The single factor analysis used t test,Multivariate linear regression analysis was used for multivariate analysis.Results:The results of univariate analysis showed that Changes of Postoperative GFR in kidney diseases were correlated with age,hypertension,BMI,R.E.N.A.L score,WIT and preoperative GFR level,and there were significant difference（P<0.05）.The results of multiple linear regression showed that the changes of Postoperative GFR were correlated with age,R.E.N.A.L score,WIT and preoperative GFR level,and the correlation was statistically significant（P<0.05）Conclusion:Age,WIT,R.E.N.A.L score and preoperative GFR in kidney diseases were risk factors for renal function recovery after laparoscopic partial nephrectomy.
