Abstract
Purpose:
To systematically explore the superiority of the transperitoneal approach in robot-assisted partial nephrectomy (TP-RAPN) and retroperitoneal approach in robot-assisted partial nephrectomy (RP-RAPN).
Methods:
Several databases were searched including PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, CBM, Wan Fang, and VIP to identify relevant studies that reported the comparison of the TP-RAPN and RP-RAPN. Outcomes of data were pooled and analyzed with Review Manager 5.3 to compare the intraoperative and postoperative variables and postoperative complications. Based on the heterogeneity of the studies, odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using a random-effect model or fixed-effect model. The sensitivity analysis and the subgroup analysis were used to minimize the effects of heterogeneity. And, publication bias was assessed by funnel plots.
Results:
In all, 16 studies met the inclusion criteria, including 2336 TP-RAPN patients and 1705 RP-RAPN patients. This meta-analysis reviewed 16 studies on RAPN, and the RP-RAPN showed shorter operative time (OT) (WMD 13.18 minutes; 95% CI 5.04–21.31; p = 0.001), shorter postoperative bowel function recovery (WMD 1.97 days; 95% CI 0.43–3.52; p = 0.01), shorter length of stay (LOS) (WMD 0.51 days; 95% CI 0.25–0.77; p = 0.0001), and lower estimated blood loss (EBL) (WMD 7.08 mL; 95% CI 1.41–12.74; p = 0.01) than the TP-RAPN. Additionally, no significant differences were found in other outcomes.
Conclusions:
In comparison, the RP-RAPN had significantly shorter OT, postoperative bowel function recovery time, LOS, and lower EBL. The RP-RAPN is associated with better value for posterior and laterally located tumors and is faster and equally safe and low costs for the patient.
