Objective: To assess the efficacy and safety of double J (DJ) stented, external stented and stent-less procedures in pediatric pyeloplasty by adopting a network meta-analysis (NMA).
Material And Methods: Electronic databases including PubMed, Cochrane Library, Web of science and Embase database were retrieved. The trials that compared double J (DJ) stented, external stented or stent-less procedures in pediatric pyeloplasty were identified. A network meta-analysis was conducted with the software of STATA 14.0. Probability-based ranking results were performed to identify the best treatment, and publication bias was analyzed by funnel plots.
Results: 15 studies with 1731 participants were enrolled in the analysis, including 4 randomized controlled trials (RCT) and 11 retrospective studies. The NMA results revealed that no significant differences were detected in the outcomes of operative time, operative success, hospital stay, improvement of renal functions, overall complications and redo pyeloplasty. DJ stented and external stented procedures were associated with more postoperative pain than that of stent-less procedures [DJ stented: OR = 4.47, 95%CI(1.05,19.08); external stented: OR = 5.83, 95%CI(0.09,1.43)]. DJ stented procedure had a lower rate of urine leakage than those of external stented procedure [OR = 0.18, 95%CI (0.04, 0.76)] and stent-less procedure [OR = 0.07, 95%CI=(0.01, 0.34)]. No significant difference was observed in other types of complications such as urinary tract infection (UTI), stent migration, recurrent ureteropelvic junction obstruction (UPJO) and fever. The probabilities of ranking results indicated that the DJ stented procedure was the best treatment in the outcomes of hospital stay, operative success, improvement of renal functions, and the complication of urine leakage. Stent-less procedure showed its advantages in the outcomes of operative time, flank pain and UTI. External stented procedure had the lowest rate of overall complications and redo pyeloplasty.
Conclusions: There were no obvious differences in operative time, operative success, hospital stay, improvement of renal functions, overall complications between external stented, DJ stented and stent-less procedures for pediatric pyeloplasty. When considering the ranking results, the DJ stented procedure seemed to be more beneficial for pediatric pyeloplasty than the other methods. However, with the limitation of our study, additional high-quality studies are needed for further evaluation.
