Bladder Compliance: How We Define It and Why It Is Important.

Bladder compliance is the relationship between detrusor pressure and bladder storage volume. We discuss the definition of compliance, how it may be accurately measured, and its clinical relevance. Specifically, we discuss the association between low compliance and upper urinary tract deterioration. We discuss medical and surgical therapies that have been demonstrated to improve compliance and reduce upper tract risk. Finally, we propose a model, which not only considers compliance but also differential pressure between the bladder and ureters, and how this may also be an accurate predictor of upper tract deterioration. We call for further investigation to test this model.
