  • Safety and Efficacy of Greenlight Laser Photoselective Vaporization for Nonmuscle-Invasive Bladder Cancer: A Meta-analysis

    ObjectiveTo systematically review the safety and efficacy of greenlight laser photoselective vaporization (PV) for nonmuscle-invasive bladder tumors (NMIBTs). MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 2, 2016), CNKI, CBM, VIP and WanFang Data were systemically searched from inception to February 2016, to collect randomized controlled trials (RCTs) investigating the efficacy and safety of greenlight PV for NMIBTs. Two reviewers independently screened literature, extracted data, assessed the risk of bias of included studies. Then RevMan 5.3 software was used for meta-analysis. ResultsA total of 11 RCTs involving 921 patients met the predefined criteria. The results of meta-analysis showed that: Compared with electrocautery transurethral resection and plasmakinetic resection in treating NMIBTs, greenlight PV could significantly shorten indwelling catheter time and hospital stay, decrease bladder perforation, obturator nerve reflex, blood loss rate and tumor recurrence rate; but the operative time between the greenlight PV group and the routine surgery group was not statistically different. ConclusionCurrent evidence shows that greenlight PV is safe and effective in treating NMIBTs. Due to the limited quality and quantity of the included studies, more large-scale high-quality studies are warranted to further assess these results.
