Phenotyping Overactive Bladder – Part 2: Can Management be Improved by Phenotyping, and Targeting Therapy According to Urgency Type and Other Characteristics? ICI‐RS 2025 Open
Introduction Management of overactive bladder (OAB) has a stepwise approach in adults and children. This does not account for individual patient variations, which may explain suboptimal outcomes in many patients. Distinct OAB profiles, bas…

A porcine bladder model of pre‐clinical urodynamics demonstrates increased afferent nerve activity during filling Open
Introduction and Objectives Urodynamics are the accepted gold standard for the evaluation of multiple forms of voiding dysfunction. However, the tests are expensive, invasive, poorly reproducible, and often prone to artifacts. Therefore, t…

Influence of visual and auditory cues about bladder volume on real-time filling sensation in healthy volunteers. Open
Auditory/visual (A/V) cues can trigger urgency in some individuals with overactive bladder (OAB), and patient-reported bladder sensation can be characterized during non-invasive oral hydration studies. The aim of this investigation was to …

Artifacts and abnormal findings may limit the use of asymptomatic volunteers as controls for studies of multichannel urodynamics Open
This study demonstrated that healthy, asymptomatic volunteers have high rates of abnormal urodynamic findings, suggesting that asymptomatic participants are not the ideal controls in research studies that involve urodynamic testing.
