Quiz - Bladder Management Flashcards
Bladder volume capacity
400-500 cc
Sympathetic nervous system
fight or flight response, originates from T11-L2, suppresses micturition reflex, inhibits detrusor, stimulates internal sphincter to stay closed
Parasympathetic nervous system
rest and digest response, originate from S2-S4, stimulates detrusor
Micturition reflex
spinal reflex that causes activation of the detrusor along with simultaneous relaxation of the urethra
Reflexive bladder physiology
Spinal reflex is intact which means when the detrusor is stretched, it sends a message to the spinal cord which responds with a reflex to open the bladder. Without signals from the brain, it may happen at an inappropriate time.
Reflexive bladder symptoms
Incontinence - large amounts of urine released at unexpected time.
Reflexive bladder management
Intermittent catheterization
May also trigger a reflex via pressing, straining, etc.
May wear briefs or condom catheter for protection.
If funding available, consider functional electrical stimulation.
Reflexive bladder complications
detrusor sphincter dyssynergia (only affects some people), pressure sores from incontinence, feelings of social isolation
Detrusor sphincter dyssynergia
external sphincter contraction occurs simultaneously with detrusor contraction (reflexive bladder only)
Reflexive bladder population (who is affected)
UMN SCI typically above T12
Areflexive bladder physiology
Spinal reflex is NOT intact which means the detrusor continues to fill and stretch until urine dribbles out.
Areflexive bladder symptoms
dribbling incontinence
Areflexive bladder management
Routine intermittent catheterization
Areflexive bladder complications
renal failure, UTI, impaired muscle tone, pressure sores from incontinence, feelings of social isolation
Areflexive bladder population (who is affected)
LMN SCI (typically below T12)
