Cognitive components of behavioral therapy for overactive bladder: a systematic review

INTRODUCTION AND HYPOTHESIS

Behavioral therapy is the first-line treatment for overactive bladder (OAB); however, the cognitive components of behavioral therapy for OAB have not been evaluated. The purposes of this systematic review were to describe the cognitive components of behavioral therapy for OAB and evaluate their effectiveness as well as to describe their rationale and origins.

METHODS

Searches were conducted on the PubMed, CINAHL, Web of Science, Cochrane and PEDro databases. Inclusion criteria were single-arm or randomized controlled trials on OAB treatment that utilized behavioral therapy, with a description of a cognitive component of the behavioral therapy. Study participants were neurologically intact adults (n = 1169). Study methodological quality was assessed with the PEDro and Newcastle-Ottawa scales.

RESULTS

Five studies were included, published between 2009 and 2020. Methodological quality was variable. All studies reported a reduction of symptoms in participants receiving behavioral therapy. Cognitive components of behavioral therapy were not extensively described. Distraction was the most common cognitive strategy for managing urgency. The relative impact of the cognitive aspect of behavioral therapy could not be evaluated, and the cognitive aspects of behavioral therapy appear to be accepted wisdom, traceable to several key authors, that has not been subjected to scientific investigation.

CONCLUSIONS

Behavioral therapy for OAB appears useful, but its cognitive components are not well described, their relative importance has not been evaluated or ascertained, nor have they been rigorously studied.

An innovative, non-invasive sensation meter allows for a more comprehensive understanding of bladder sensation events: A prospective study in participants with normal bladder function

AIMS

There is currently no standardized method of characterizing changes in bladder sensation during bladder filling outside of the urodynamics laboratory. The purpose of this investigation was to characterize real-time bladder sensation events using a sensation meter during oral hydration in individuals with normal bladder function.

METHODS

Participants enrolled in an accelerated hydration study drank 2 L Gatorade-G2® and utilized a sensation meter to record real-time bladder sensation (0-100%), verbal sensory thresholds, and sensation descriptors of "tense," "pressure," "tingling," "painful," and "other" for two consecutive fill-void cycles.

RESULTS

Data from 21 participants (12 females/9 males) were obtained and demonstrated an average of 8-9 sensation events (significant changes in sensation) per fill with no differences in the total number of sensation events and volume between sensation events (fill 1 vs fill 2). An increased number of sensation events occurred at higher capacity quartiles. Event descriptors of "pressure" and "tingling" were the most commonly chosen descriptors in both fills.

CONCLUSIONS

The innovative sensation meter includes the sensation event descriptors of "tense," "tingling," "pressure," and "painful," to enable a more comprehensive understanding of bladder sensation as well as real-time identification, quantification, and characterization of sensation events. The study demonstrates 8-9 events per fill, acceleration of sensation during filling, and unique sensation event descriptor patterns. This technology may be helpful in the identification of novel sensation patterns associated with overactive bladder (OAB) and aging.
