What causes detrusor instability?
Detrusor instability is the likely diagnosis when there is no neurological cause for involuntary bladder contractions. When the condition is successfully treated, symptoms normally disappear. Reasons for detrusor instability include: • Poor voiding habits (not voiding completely – this leaves the bladder.
Is the detrusor muscle voluntary or involuntary?
Bladder contains a big involuntary muscle called detrusor (covering the whole bladder, made of smooth muscles), an involuntary “gate” called internal urinary sphincter (made of smooth muscles) and a voluntary “gate” called external urinary sphincter (made of striated muscles).
What is detrusor instability?
Detrusor instability is characterised by spontaneous and uninhibited contraction of the detrusor muscle during bladder filling. The bladder pressure exceeds the urethral pressure resulting in incontinence (the urethral opening pressure is higher in women with detrusor instability than in those with stable bladders).
