Analysis of clinical curative effect of using different blocking methods to renal artery in laparoscopic nephron sparing surgery / 中国基层医药

ABSTRACT

Objective To explore the clinical curative effect of using different blocking methods to renal artery in laparoscopic nephron sparing surgery.Methods A total of 118 cases admitted in the Affiliated Heji Hospital of Changzhi Medical College who reserved the nephron routine after laparoscopic surgery of renal tumor surgery were selected.According to different methods of renal artery block,the patients were divided into the whole block group (61 cases) and selective blocking group (57 cases).The clinical curative effects of the two groups were compared.Results The differences of age,sex,suffering from kidney area and excising were not statistically significant between the two groups(all P ＞ 0.05).The blocking time,operation time and intraoperative blood loss,drainage at postoperative 1 day in the whole block group were (22.58 ± 4.62) min,(138.75 ± 21.76) min,(108.47 ± 75.39) mL and (137.36 ±18.34) mL,respectively,which in the selective block group were (28.61 ± 4.59) min,(103.26 ± 18.64) min,(132.58 ± 68.43) mL and (163.15 ± 15.87) mL,respectively,the differences were significant between the two groups (t =5.356,-8.247,7.463,10.358,all P ＜ 0.01).The postoperative hospital stay [(8.36 ± 2.19) d vs.(7.78 ±2.35)d] had no statistically significant difference between the two groups(P ＞0.05).There were no statistically significant differences in preoperative creatinine level and glomerular filtration rate between the two groups (all P ＞0.05).After operation,the creatinine and glomerular filtration rate in the whole block group were (106.38 ±32.76) μmol/L,(33.53 ± 6.14) ％ statistically,which in the selective block group were (95.26 ± 25.49) μmol/L,(38.27 ± 5.29)％ statistically,the differences were statistically significant between the two groups (t =-2.154,4.572,all P ＜ 0.05).Conclusion Renal artery block has shorter operation time,larger haemorrhage amount,increased postoperative creatinine,reduced glomerular filtration rate,for a small single kidney surgery,using selective renal artery block as far as possible,it has less intraoperative bleeding,and postoperative effect is better.
