Systematic Review and Meta-Analysis of Pediatric Robot-Assisted Laparoscopic Pyeloplasty
Abstract
Introduction: To perform a systematic review (SR) and meta-analysis (MA) of outcomes of robot-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction (UPJ) obstruction in children. Evidence Acquisition: A SR of the English-language literature on surgical techniques and perioperative outcomes of RALP for UPJ obstruction in children was performed without time filters using the MEDLINE (through PubMed), EMBASE, and Cochrane databases in July 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement recommendations. Evidence Synthesis: Overall, 58 studies were selected for qualitative analysis, 46 of which were included in the MA. Nearly all studies included were observational and retrospective, either cohort or case-control. The quality of evidence was assessed using Modified Newcastle-Ottawa Scoring, with the majority of studies scoring medium or high quality. The mean success rate was 95.4% (confidence interval 91.0%-99.3%), over a wide age range. There was a noticeable heterogeneity in reported follow-up length and definitions of success rate. The majority of studies reported length of stay of ∼1 day. The mean overall complication rate was 12%. For studies that reported complication rate by grade, the mean low Clavien grade (Grade 2 or less) complication rate was 9.3% and the mean high Clavien grade (Grade 3 or more) complication rate was 6.5%. Conclusions: Robot-assisted surgery is technically feasible and has been shown…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
