In older adults over 60 years in age, the detrusor muscle may cause issues in voiding the bladder, resulting in uncomfortable urinary retention. [5] The bladder also contains β 3 adrenergic receptors, and pharmacological agonists of this receptor are used to treat overactive bladder.
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 ...
Prevalence increases with age. The prevalence of nocturia in older men is about 78%. Older men have a higher incidence of LUTS than older women. [25] Around one third of men will develop urinary tract (outflow) symptoms, of which the principal underlying cause is benign prostatic hyperplasia. [26]
Urge urinary incontinence, is caused by uninhibited contractions of the detrusor muscle, a condition known as overactive bladder syndrome. This type of urinary incontinence is more commonly seen in women of older age. [17] It is characterized by leaking of large amounts of urine in association with insufficient warning to get to the bathroom in ...
In the longer term, obstruction of the urinary tract may cause: [citation needed] Bladder stones; Atrophy of the detrusor muscle (atonic bladder is an extreme form) Hydronephrosis (congestion of the kidneys) Hypertrophy of the detrusor muscle (the muscle that squeezes the bladder to empty it during urination)
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 ...
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 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]
