The detrusor muscle, also detrusor urinae muscle, muscularis propria of the urinary bladder and (less precise) muscularis propria, is smooth muscle found in the wall of the bladder. The detrusor muscle remains relaxed to allow the bladder to store urine , and contracts during urination to release urine.
Without diagnostic evaluation, the cause of underactive bladder is unclear, as there are multiple possible causes. UAB symptoms can accurately reflect impaired bladder emptying due either to DU or obstruction (normal or large storage volumes, elevated post-void residual volume), or can result from a sense of incomplete emptying of a hypersensitive bladder (small storage volumes, normal or ...
Bladder sphincter dyssynergia (also known as detrusor sphincter dyssynergia (DSD) (the ICS standard terminology agreed 1998) [1] and neurogenic detrusor overactivity (NDO)) is a consequence of a neurological pathology such as spinal injury [2] or multiple sclerosis [3] which disrupts central nervous system regulation of the micturition (urination) reflex resulting in dyscoordination of the ...
The cause of this might be detrusor overactivity, in which the bladder muscle (the detrusor) contracts unexpectedly during bladder filling. Urodynamics can be used to confirm the presence of detrusor overactivity, which may help guide treatment. An overactive detrusor can be associated with urge incontinence. The American Urogynecologic Society ...
It is often associated with overactivity of the detrusor urinae muscle, a pattern of bladder muscle contraction observed during urodynamics. [17] It is also possible that the increased contractile nature originates from within the urothelium and lamina propria, and abnormal contractions in this tissue could stimulate dysfunction in the detrusor ...
Physical activity has been recommended as a treatment for urinary tract symptoms. A 2019 Cochrane review of six studies involving 652 men assessing the effects of physical activity alone, physical activity as a part of a self-management program, among others. [ 20 ]
This incontinence is associated with sudden forceful contractions of the detrusor muscle (bladder muscle), leading to an intense feeling of urination, and incontinence if the person does not reach the bathroom on time. The syndrome is known as overactive bladder syndrome, and it's related to dysfunction of the detrusor muscle. [25]
Neurostimulation treatment of adult enuresis may be considered prior to pursuing surgical methods. For adult enuresis, sacral nerve stimulation can be administered to decrease bladder muscle activity so that the bladder muscles are not constantly in a contracted state to help improve enuresis symptoms.
