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 most valuable test to test for detrusor sphincter dyssynergia (DESD) is to perform cystometry simultaneously with external sphincter electromyography (EMG). [8] Uroflowmetry is a less-invasive study that can measure urine flow rate and use it to estimate detrusor strength and sphincter resistance.
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 ...
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 ...
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 can also contract for a long time whilst voiding , and it stays relaxed whilst the bladder is filling. [ 9 ]
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.
This results in loss of detrusor contraction, difficulty in initiating micturition and overflow incontinence. Anticholinergic side effects of certain medications (for example, certain antipsychotics and antidepressants ) may cause urinary retention which may lead to overflow incontinence.
Overactive bladder (OAB) is a common condition where there is a frequent feeling of needing to urinate to a degree that it negatively affects a person's life. [2] The frequent need to urinate may occur during the day, at night, or both. [4]
