The Self-Retaining Barbed Suture for Parenchymal Repair in Laparoscopic Partial Nephrectomy: A Systematic Review and Meta-Analysis.

. The warm ischemia time (WIT) is key to successful laparoscopic partial nephrectomy (LPN). The aim of this study was to perform a meta-analysis comparing the self-retaining barbed suture (SRBS) with a non-SRBS for parenchymal repair during LPN. A systematic search of PubMed, Scopus, and the Cochrane Library was performed up to March 2018. Inclusion criteria for this study were randomized controlled trials (RCTs) and observational comparative studies assessing the SRBS and non-SRBS for parenchymal repair during LPN. Outcomes of interest included WIT, complications, overall operative time, estimated blood loss, length of hospital stay, and change of renal function. One RCT and 7 retrospective studies were identified, which included a total of 461 cases. Compared with the non-SRBS, use of the SRBS for parenchymal repair during LPN was associated with shorter WIT ( < .00001), shorter overall operative time ( < .00001), lower estimated blood loss ( = .02), and better renal function preservation ( = .001). There was no significant difference between the SRBS and non-SRBS with regard to complications ( = .08) and length of hospital stay ( = .25). The SRBS for parenchymal repair during LPN can significantly shorten the WIT and overall operative time, decrease blood loss, and preserve renal function.
