The Underactive Bladder: a New Clinical Concept?

Unlabelled: Detrusor underactivity (DU) is an increasingly recognised cause of lower urinary tract symptoms in both men and women. There has been a lack of research into all aspects of this dysfunction, and as yet, no effective treatments exist. DU can be diagnosed at present only on the basis of an invasive urodynamic study. An international consensus group met at the International Consultation on Incontinence-Research Society and International Continence Society annual meetings in 2014 to consider the feasibility of developing a working definition of a symptom complex associated with DU. Drawing an analogy to detrusor overactivity (urodynamic diagnosis) and overactive bladder (symptom complex), the aim of this process is to help identify affected patients and facilitate further clinical and epidemiological research.

Patient Summary: Bladder underactivity is an underresearched but important cause of urinary symptoms in men and women. In this paper, an international expert group presents a working definition for the symptoms that characterise bladder underactivity, with the aim of facilitating further research in this area.
