Abstract
OBJECTIVE: To compare the efficacy and safety of robot-assisted laparoscopic ureteral reimplantation (RALUR) and open ureteral reimplantation (OUR) in treating primary pediatric vesicoureteral reflux (VUR) based on published literature. METHODS: A comprehensive literature search of PubMed, Embase, Cochrane Library, CBM, CNKI and VIP databases was conducted to identify studies comparing the outcomes of RALUR with OUR for treating primary pediatric VUR. The last search was in January 2017. Summarized mean differences (MDs) or odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the differences in outcomes between RALUR and OUR. RESULTS: A total of six studies containing 7122 children with primary VUR were included in this analysis. Significantly longer operation time was needed for RALUR than OUR (MD 66.69 min, 95% CI 41.71-91.67, P < 0.00001), while the RALUR group had significantly fewer days of hospital stay (MD - 17.80 h, 95% CI - 21.18 to - 14.42, P < 0.00001) and postoperative Foley placement (MD - 0.32 days, 95% CI - 0.57 to - 0.07, P = 0.01). No significant differences were found in estimated blood loss during operation, success rate, complications, and postoperative analgesia usage between the two groups. In subgroup analyses, a significantly higher rate of short-term postoperative complications in RALUR was found compared with OUR (OR 3.17, 95% CI 1.72-5.85, P = 0.0002). CONCLUSIONS: Our study indicates that compared with OUR, RALUR is also an effective surgical approach for primary pediatric VUR and could help patients return to society more quickly; however, short-term postoperative complications of RALUR should be considered cautiously.
