Behavioral Therapies for Overactive Bladder

Abstract

Overactive bladder (OAB) is a symptom-based syndrome characterized by the presence of urgency, which is defined as a sudden and compelling desire to void that cannot be postponed. OAB may significantly impact of quality of life. Numerous treatment options exist for OAB, including behavioral therapies such as pelvic floor muscle rehabilitation, bladder training, and dietary modification, as well as traditional therapies such as pharmacological therapy and neuromodulation. Behavioral therapies are considered the mainstay of treatment for urinary incontinence in general. However the efficacy of these noninvasive strategies for OAB treatment has not been well addressed in the literature. This article presents an overview of current evidence with attention to the clinical relevance of findings related to lifestyle modification, bladder training, and pelvic floor muscle training. Initial evidence suggests that obesity, smoking, and consumption of carbonated drinks are risk factors for OAB but there is less support for the contributory role of caffeine or the impact of caffeine reduction. The evidence supporting bladder training and pelvic floor muscle training is more consistent and a trend towards combining these therapies to treat OAB appears positive. Given the prevalence of OAB and growing support for the efficacy of behavioral treatments it is important and timely to augment existing evidence with well-designed multicenter trials.
