摘要

Three databases were searched for studies evaluating SP versus MP RAPN. Continuous outcomes were pooled as mean differences (MD) and binary variables as odds ratios (OR) with 95% confidence intervals (CI). Fixed- or random-effects models were applied depending to heterogeneity. Prespecified subgroup analyses were conducted based on propensity-score matching and surgical approach. Fifteen studies comprising 2,689 patients (902 SP and 1,787 MP) were included, predominantly retrospective cohorts, with eight propensity-score–matched analyses. Four studies were of good quality and eleven were fair quality. Compared with MP RAPN, SP RAPN was associated with lower estimated blood loss (MD − 15.72 mL; 95%CI: −23.73 to − 7.71), shorter length of stay (MD − 0.43 days; 95%CI: −0.84 to − 0.20), and lower postoperative pain scores (MD − 0.33 on VAS; 95%CI: −0.59 to − 0.08). Ischemia time was longer with SP RAPN (MD 6.06 min; 95%CI: 0.98 to 11.14). Operative time, postoperative eGFR, oncologic outcomes, complications, and mortality were comparable between groups, with subgroup analyses showing no consistent effect modification. SP RAPN appears to provide perioperative and short-term oncologic outcomes comparable to MP RAPN, with modest improvements in selected recovery parameters. Differences in ischemia time remain uncertain due to substantial heterogeneity and low certainty of evidence.
