Abstract Introduction: Overactive bladder (OAB) is a clinical diagnosis of irritating urinary symptoms that influence on sufferers' life quality. There are effective treatments described in literature, but most of them present adverse effects. One way of treatment is the use of electrical stimulation, which has been widely used, but studies show varying results. Objective: To verify if intracavitary electrical stimulation can be effective in patients with OAB. Methods: online databases were searched with specific descriptors to find randomized clinical trials on overactive bladder treated with intracavitary electrical stimulation. Only articles with score equal or higher than 5 in methodological PEDro scale were used and those that described intra and / or inter-group P-value. Results: 217 articles were found, but only 6 were analyzed by the selection criteria. The studies show that electrical stimulation promotes the reduction of urinary frequency, urinary incontinence, nocturia, urgency and the number of protectors used, and improvements in maximum cystometric bladder capacity, symptoms of OAB and quality of life. Conclusion: Electrical stimulation was effective in patients with OAB and can be used before any invasive treatment due to none side effects.
