The bladder also contains β 3 adrenergic receptors, and pharmacological agonists of this receptor are used to treat overactive bladder. The mucosa of the urinary bladder may herniate through the detrusor muscle. [6] This is most often an acquired condition due to high pressure in the urinary bladder, damage, or existing connective tissue ...
The physical finding of detrusor activity of insufficient strength or duration to ensure efficient bladder emptying is properly termed "detrusor underactivity" (DU). [1] Historically, UAB and DU (as well as others such as 'bladder underactivity') have been often used interchangeably, [2] leading to both terminologic and pathophysiologic confusion.
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 ...
The walls of the bladder have a series of ridges, thick mucosal folds known as rugae that allow for the expansion of the bladder. The detrusor muscle is the muscular layer of the wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles. [8] The detrusor muscle is able to change its length.
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 ...
Bladder pressure can be measured by cystometry, during which the bladder is artificially filled with a catheter and bladder pressures and detrusor activity are monitored. Patterns of involuntary detrusor activity as well as bladder flexibility, or compliance, can be evaluated.
Bladder sphincter dyssynergia also known as detrusor sphincter dyssynergia is the decrease of detrusor (wall muscle of the bladder) pressure which causes unwanted urination. This is very common in spinal cord injuries and multiple sclerosis patients. There is a malfunction between the central nervous system, urinary sphincters, and detrusor ...
The internal sphincter muscle of urethra: located at the bladder's inferior end and the urethra's proximal end at the junction of the urethra with the urinary bladder. The internal sphincter is a continuation of the detrusor muscle and is made of smooth muscle, therefore it is under involuntary or autonomic control.
