What is reflex neurogenic bladder?

Reflex neurogenic bladder describes the post-spinal shock condition that exists after complete interruption of the sensory and motor pathways between the sacral spinal cord and the brain stem.

What spinal cord injury causes neurogenic bladder?

Suprasacral Neurogenic Bladder occurs due to spinal cord injury between the brainstem and sacral center. This leads to disinhibited sacral reflexes, overactivity of the detrusor, overactivity of the external and/or internal sphincters, and impaired coordination between these two muscles.

How do you assess for neurogenic bladder?

When assessing neurogenic bladder, a panel of lab tests including urinalysis, urine culture, serum blood urea nitrogen (BUN) and creatinine, and creatinine clearance are ordered.

What is the pathophysiology of neurogenic bladder?

Brain stem or spinal cord damage between the sacral and pontine micturition centers results in neurogenic detrusor overactivity that exhibits as uninhibited bladder contraction and detrusorsphincter dyssynergia in which the sphincter activity is often uncoordinated in relation to bladder contraction.

How do I know if I have neurogenic bladder?

The most common symptom of neurogenic bladder is being unable to control urination. Other neurogenic bladder symptoms include: A weak or dribbling urinary stream. Frequent urination (urinating eight or more times daily).

Which nervous system controls bladder?

The sympathetic nervous system regulates the process of urine storage in the bladder. In contrast, the parasympathetic nervous system controls bladder contractions and the passage of urine.

Who has neurogenic bladder?

Millions of people have neurogenic bladder. This includes people with Multiple Sclerosis (MS), Parkinson’s disease and spina bifida. It also could include people who have had a stroke, spinal cord injury, major pelvic surgery, diabetes or other illnesses.

What are the two reflexes that control urination?

The micturition reflex is a bladder-to-bladder contraction reflex for which the reflex center is located in the rostral pontine tegmentum (pontine micturition center: PMC). There are two afferent pathways from the bladder to the brain. One is the dorsal system and the other is the spinothalamic tract.

What nerve stimulates the bladder?

Pelvic parasympathetic nerves: arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra. Lumbar sympathetic nerves: inhibit the bladder body and excite the bladder base and urethra.

How does the urinary bladder respond to the micturition reflex?

When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition reflex. The detrusor muscle that surrounds the bladder contracts. The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra. Both of these reactions are involuntary.

Rounded bladder with a trabeculated apperance to the mucosa above the trigone from detrusor contractions. Reflex neurogenic bladder. Results from detrusor hyperreflexia with a dyssynergic sphincter. This leads to contrast extension to the posterior urethra and an elongated pointed urthera with pseudodverticula.

What are the neurogenic bladder symptoms?

Neurogenic bladder symptoms include: a dribbling stream when urinating. an inability to fully empty your bladder. straining during urination. a loss of bladder control.

What are sensory and uninhibited neurogenic bladder lesions?

sensory neurogenic bladder: posterior columns of the spinal cord or afferent tracts leading from the bladder uninhibited neurogenic bladder: incomplete spinal cord lesions above S2 or cerebral cortex or cerebropontine axis lesions Generally a markedly contracted or distended bladder.

What should be included in patient education about neurogenic bladder?

The patient with a neurogenic bladder who is on catheter should receive education about catheter care and urinary output monitoring. If a patient is on clean intermittent catheterization (CIC), it is crucial to teach proper techniques of  CIC use to prevent complications.
