RESUMO
The aim of this study was to systematically review randomized clinical trials comparing the treatment of individuals with overactive bladder syndrome through the use of behavioral therapy versus drug therapy. A systematic electronic search of MEDLINE via PubMed, Embase, and Cochrane Library was performed, including studies indexed until August 2019. Five randomized clinical trials were included. The studies presented a high risk of bias. There was no significant difference between the evaluated treatments. Thus, behavioral therapy and drug therapy also promote the improvement of the symptoms of overactive bladder syndrome, and the behavioral therapy does not have significant adverse effects reported. Due to the high risk of bias in included studies, data should be interpreted with caution. Future studies with more comprehensive protocols may change the effect estimates of behavioral therapy on overactive bladder syndrome.
