OBJECTIVE: To compare the clinical effectiveness and safety of alpha-blocker alone and combined tamsulosin with an anticholinergic drug for bladder outlet obstruction (BOO) with overactive bladder (OAB).
METHODS: Literature search was performed using PubMed, EMBASE, Ovid, Wanfang, and CNKI from inception to October 2013 for comparative studies assessing alpha-blocker alone and combined alpha-blocker with an anticholinergic drug for BOO+OAB. Data were extracted and evaluated by two reviewers independently according to the Cochrane Handbook for systematic reviews. Meta-analyses were conducted using RevMan 5.2.
RESULTS: A total of 7 studies involving 3 458 patients were included for the analysis. The values of total IPSS and storage IPSS reduced significantly after treatment in combination group (RR = -0.23, 95%CI: -0.44--0.02, P = 0.03; RR = -0.69, 95%CI: -0.88--0.51, P < 0.01). There were no significant differences between the two groups in voiding IPSS and Qmax (P = 0.86 and 0.89). The incidences of dry mouth (OR = 2.53), constipation (OR = 3.74), dizziness (OR = 0.73), and urinary retention (OR = 0.26) were higher in combination group than in alpha-blocker alone group (P < 0.05). But most adverse events were mild in degree.
CONCLUSION: Alpha-blocker combined with an anticholinergic drug in the treatment of BOO+OAB was better than that of alpha-blocker alone, and was safe and well tolerated.
