ABSTRACT
The present study aimed to compare the efficacy and safety between robot-assisted nephroureterectomy (RANU) and open nephroureterectomy (ONU) for the treatment of upper tract urothelial carcinoma (UTUC). We systematically searched four electronic databases (PubMed, Embase, Web of Science, and Cochrane Library) to locate pertinent studies published in English up to January 2023. The primary outcomes evaluated included perioperative results, complications, and oncologic outcomes. Statistical analyses and calculations were performed using Review Manager 5.4. The study was registered with PROSPERO (ID: CRD42022383035). In total, eight comparative trials, including 37,984 patients were enrolled. Compared to ONU, RANU was associated with a significantly shorter length of stay (weighted mean difference [WMD] – 1.63 days, 95% confidence interval [CI] – 2.90, – 0.35; p = 0.01), less blood loss (WMD – 107.04 mL, 95% CI – 204.97, – 9.11; p = 0.03), less major complication(OR 0.78, 95% CI 0.70, 0.88; p < 0.0001), and lower positive surgical margin (PSM) (OR 0.33, 95% CI 0.12, 0.92; p = 0.03). However, no statistically significant differences were observed between the two groups in operative time, transfusion rates, rate of lymph node dissection, lymph node yield, overall complications, overall survival, cancer-specific survival, recurrence-free survival, and progression-free survival. RANU has superior advantages compared to ONU in terms of length of hospital stay, blood loss, postoperative complications, and PSM, while providing comparable oncologic outcomes in patients with UTUC.
