Underactive Bladder Syndrome (UAB) is a urological condition characterized by bladder underactivity causing difficulty in voiding, resulting in incomplete bladder emptying.〔 Rigby D Underactive Bladder Syndrome. ''Nursing Standard.'' 2005 May 11–17;19(35):57-64; quiz 66-7.〕 UAB is often referred to by the general scientific community as detrusor underactivity.〔 Miyazato M, Yoshiumura N, Chancellor M. The Other Bladder Syndrom: Underactive Bladder. ''Reviews In Urology.'' 2013; 15(1):11-22.〕 Patients with UAB have a diminished sense of when the bladder is full and are not able to contract the muscles sufficiently, resulting in incomplete bladder emptying. The International Continence Society (ICS) refers to the condition of detrusor underactivity, defined as a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or failure to achieve complete bladder emptying within a usual time span. UAB may cause overdistention of the bladder, resulting in overflow incontinence. The disease can have a profound impact on quality of life. ==Causes== The cause of UAB is unclear, however there are multiple possible causes of the syndrome. UAB symptoms are sometimes a result of neurological damage, surgery, medication side effects, and infection. In addition to these sources, the simple act of aging can result in the decline of bladder volume and elasticity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Underactive bladder」の詳細全文を読む スポンサード リンク
