Safety of robot-assisted laparoscopic and laparoscopic heminephrectomy: a meta analysis / 现代泌尿外科杂志

ABSTRACT

【Objective】 To analyze the differences in efficacy of heminephrectomy with robot-assisted laparoscopy (RARN) and laparoscopic radical nephrectomy (LRN). 【Methods】 The published references in national and international databases on the comparison of clinical outcomes between heminephrectomy RARN and LRN for kidney neoplasms were searched. References were screened strictly according to PICOS criteria, and data including estimated amount of blood loss, operation time, length of hospital stay and complications were extracted from those that met the requirements. Sensitivity analysis was used to eliminate the included articles one by one to confirm the robustness of the results, and funnel plot and Eggers test were used to explore publication bias. 【Results】 A total of 16 studies involving 2 063 patients (1 097 in RARN group and 966 in LRN group) were included. The RARN group had less intraoperative blood loss and shorter hospital stay, but there were no significant differences between the two methods (P>0.05). The incidence of postoperative complications in RARN group was lower than that in LRN group (OR 0.643, 95%CI 0.467-0.886, P=0.007). 【Conclusion】 Compared with LRN, RARN has better control of complications in the treatment of renal tumor, but the overall effects of intraoperative bleeding, operation time, and hospital stay are comparable.
