Retroperitoneal laparoscopic partial nephrectomy without blockage of renal pedicle for the treatment of uncomplex renal tumor / 中国基层医药

ABSTRACT

Objective To evaluate the efficacy and clinical significance of partial laparoscopic resection of renal pedicle without renal pedicle vascular resection in the treatment of low renal complex tumors.Methods Retrospective analysis of retroperitoneal laparoscopic renal artery clamping without partial nephrectomy in the treatment of the patients with low-grade complex renal tumors in 10 cases(observation group) and the clinical data of retroperitoneal laparoscopic renal pedicle occlusion of renal vascular resection in 10 patients (control group) were analyzed.The amount of bleeding,operation time,the average hospitalization time,drainage tube placement after operation,the hemoglobin (Hb),serum creatinine(Ccr) and glomerular filtration rate(GFR) changes were observed in the two groups.Results The operation time,bleeding volume,postoperative drainage tube placed time,postoperative hospitalization time of the observation group were (103.0 ± 42.7) min,(100.0 ± 70.4) mL,(3.5 ± 1.2) d,(5.0 ± 1.2) d,respectively,which of the control group were (129.2 ± 57.5) min,(89.2 ± 9.5) mL,(6.5 ± 9.7) d,(6.3 ± 3.4) d,respectively,there were statistically significant differences between the two groups (t =4.23,3.23,1.57,4.24,all P ＜0.05).Before operation,the Hb,Ccr and GFR between the two groups had no statistically significant differences(all P ＜0.05).After operation,the Hb,Ccr and GFR of the control group were (85.7 ± 18.2) g/L,(77.9 ± 22.1) μmol/L,(61.4 ± 50.9) mL · min-1 · 1.73 (m2)-1,respectively,which of the observation group were (95.6 ± 13.5) g/L,(70.2 ± 10.5) μmol/L,(85.5 ± 5.1) mL · min-1 · 1.73 (m2)-1,respectively,there were statistically significant differences between the two groups(t =9.34,7.44,7.34,all P ＜0.05).Conclusion Retroperitoneal laparoscopic renal partial nephrectomy without blocking renal pedicle vessels is a safe and effective method for the treatment of low complexity renal tumors.It has advantages of simple operation and is beneficial to the recovery of patients'function.
