Abstract
Background
For medical institutions without robotic equipment, it remains uncertain whether laparoscopic radical nephroureterectomy (LNU) can achieve results similar to those of robotic surgery for the treatment of upper tract urothelial carcinoma (UTUC). This meta-analysis aimed to compare the efficacy and safety of robot-assisted radical nephroureterectomy (RANU) with that of LNU using a large sample size of patients.
Methods
A systematic meta-analysis was performed using data (available to May 2022) acquired from multiple scientific databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines, according to the protocols registered with PROSPERO (CRD42021264046), were followed to perform this cumulative analysis.
Results
Nine high-quality studies were included in this analysis, considering factors such as operative time (OT), estimated blood loss (EBL), length of hospital stay (LOS), positive surgical margins (PSM), and complications. Statistical indicators revealed no significant differences between the RANU and LNU groups in terms of OT (weighted mean difference [WMD] 29.41, 95% confidence interval [CI] −1.10 to 59.92; p = 0.22), EBL (WMD −55.30, 95% CI −171.14 to 60.54; p = 0.13), LOS (WMD −0.39, 95% CI −1.03 to 0.25; p = 0.12), PSM (odds ratio [OR] 1.22, 95% CI 0.44–3.36; p = 0.17], or complications (OR 0.91, 95% CI 0.49–1.69; p = 0.13).
Conclusion
The meta-analysis showed that the perioperative and safety indicators of both RANU and LNU were similar and both showed favorable outcomes in UTUC treatment. However, some uncertainties remain in the implementation and selection of lymph nodes for dissection.
