Pathophysiology of Detrusor Underactivity/Acontractile Detrusor
According to the standardization of terminology from the International Continence Society, 1 detrusor under-activity (DU) is urodynamically defined as a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span. Acontractile detrusor (AD) is one that cannot be demonstrated to contract during urodynamic studies. DU or AD (DU/AD) can be developed from various kinds of conditions, when afferent and/or efferent pathways innervating the bladder are mainly damaged. Various myogenic factors in detrusor muscles also cause AD as well as DU.
