The effect of ureteral stenting before flexible ureteroscopic lithotripsy: a Meta-analysis / 中华泌尿外科杂志

ABSTRACT

Purpose To evaluated the effect of ureteral stent placement before flexible ureteroscopic lithotripsy(FURL).Methods A systematic search of PubMed,Cochrane Library,Embase,Scopus,VIP,CNKI,Wanfang database from databases establishment to February 2017 was performed to identify all clinical trials on the effect of ureteral stenting before flexible ureteroscopic lithotripsy.The outcomes included stone-free rate,mean operative time,success rate of ureteral access sheath placement and postoperative complications.RevMan 5.3 software was used to complete the Meta statistical analysis.Results Three randomized and four non-randomized studies were analyzed,which consisted of 1 176 patients including 788 cases in experimental group,388 cases in control group.Meta-analysis showed significant differences between experimental group and control group in stone-free rate (OR =1.88,95％ CI 1.30-2.71,P ＜ 0.001).There was no statistically significant difference in mean operative time between experimental group and control group (WMD =-0.99,95 ％ CI-10.63-8.65,P =0.84).The success rate of ureteral access sheath placement was significantly higher in experimental group than that in the control group (OR =8.24,95％ CI 3.17-21.45,P ＜ 0.001).In term of postoperative complications,two groups had significant differences (OR =0.57,95 ％ CI 0.33-0.99,P =0.04).Conclusions Preoperative ureteral stenting can increase the stone-free rate and the success rate of ureteral access sheath placement,and reduce complications of FURL.There is no statistically significant difference in mean operative time.
