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, 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.
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 ...
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]
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 ...
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 ...
The muscle helps maintain continence of urine along with the internal urethral sphincter which is under control of the autonomic nervous system.The external sphincter muscle prevents urine leakage as the muscle is tonically contracted via somatic fibers that originate in Onuf's nucleus and pass through sacral spinal nerves S2-S4 then the pudendal nerve to synapse on the muscle.
In humans and other mammals, neurons in the PMC send descending excitatory projections to spinally located parasympathetic neurons controlling the detrusor muscle of the bladder and inhibitory interneurons regulating Onuf's nucleus. Additionally, the PMC receives ascending input from the level of the lumbosacral spinal cord.
