Objective To provide objective basis for clinical decision through efficacy evaluation of randomized controlled trial on moxibustion in treatment of urinary retention.Methods Chinese National knowledge Infrastructure(CNKI),China Biology Medicine disc(CBM),VIP,Wanfang Data,and Sciencedirect were retrieved.The objects screened were from January 1,1990 to June 30,2013.Irrelevant,repeated and non-randomized controlled trials were excluded,and randomized controlled trials on moxibustion in treatment of urinary retention conforming to the inclusive criteria were selected.The quality of randomized controlled trials conforming to the inclusive criteria was evaluated using Jadad Scale,and the trials were analyzed statistically via RevMan5.2software.The randomized controlled trials on moxibustion in treatment of urinary retention were evaluated systematically through Cochrane systematic review.Results Nineteen references with better homogeneity were included into the study.Based on Meta-analysis result,the consolidated effect size OR=6.95,95%C/(5.12,9.44),consolidated effect size test Z=12.43,P〈0.000 01,and the difference was statistically significant,indicating that the moxibustion group might be superior to control group,and the efficacy of moxibustion in treatment of urinary retention was better.It was shown from funnel plot that the subjects distributed symmetrically,indicating small bias of study.Conclusion Moxibustion in treatment of urinary retention has a certain efficacy but there are some small sample size and low-quality literature in the study,big sample size and high-quality and formal randomized controlled trials are needed to study in the futher.
