DU itself is often linked to a weak detrusor muscle (impaired contractility), however this association is weak. Both UAB and DU have been associated with diminished sensitivity to bladder volumes rather than objective detrusor weakness, suggesting both symptoms (UAB) and function (DU) have a significant component of sensory dysfunction, leading ...
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.
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 ...
Continence and micturition involve a balance between urethral closure and detrusor muscle activity (the muscle of the bladder). During urination, detrusor muscles in the wall of the bladder contract, forcing urine out of the bladder and into the urethra. At the same time, sphincter muscles surrounding the urethra relax, letting urine pass out ...
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.
Detrusor muscle weakness and/or instability; Diabetes; Use of ketamine [12] Neurological conditions; for example multiple sclerosis, spinal cord injury, cauda equina syndrome; Prostatitis, including IgG4-related prostatitis [13] [14] [15] Urethral stricture; Urinary tract infections (UTIs) [16]
Treatment depends on the type of neurogenic bladder and other medical problems. Treatment strategies include catheterization, medications, surgeries or other procedures. The goals of treatment focus on preserving the structure and function of the upper urinary tract, and on improving the quality of life for patients with neurogenic bladder. [2]
