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, 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.
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 ...
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]
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 ...
Subjective success rates, based on patient's desire to continue treatment, range from 46.7% to 59%. [16] Implantable neuromodulator devices: An implantable device is used to stimulate the sacral nerves leading to the contraction of the detrusor muscle. This technique can be combined with posterior rhizotomy to reduce detrusor hyperreflexia. [17]
Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis. [11] Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy.
Catheters are preferred over externally-applied pressure (such as with hands) or straining of the abdomen, even when these methods succeed in completely emptying the bladder. Those techniques can elevate the pressure inside the detrusor muscle of the bladder and cause additional bladder dysfunction, or even rupture the bladder. [2]
