Urinary incontinence Flashcards
what is epi for stress incontinence
- almost only women
- can be any age
what are 3 important parts of bladder innervation
- Parasympathetic (S2-4) (muscarinic-r) - excite bladder and relax urethra
- Sympathetic (T10-L2)- inhibit bladder body (beta 3 receptors) , excite bladder base and urethra (alpha 1)
- Somatic - stim of the pudendal nerve exites the external striated urethral sphincter
what are afferent, efferent, and central pathways for storage phase
afferent - low level activity - bladder not full
efferent - sphyincter contraction, detrusor relax
central - spinal relfexes
what are afferent, efferent, and central pathways for voiding phase
afferent - high level activity - bladder full
efferent - inhibit sphincter, avtivate detrusor
central - spino-bulbospinal
3 main types of incontinence
- failure to store
- failure to empty
- mixed
2 types of failure to store
- urgency - overactive bladder
2. stress - outlet incompetence
2 types of failure to empty
- due to hypotonic bladder
- outlet - obstruction
- mixed
def. overactive bladder
URGENCY with ot without incontinence
- wet or dry type
mech. of overactive bladder
- UMN disease of bladder
- detrusor muscle contract spontaneously
mech. stress urinary incontinence
- abdo pressure exceeds the sphintcer
- mostly women
- parity, obesity, COPD, constipation
5 basic parts to exam
- Hx
- Phx
- urinalysis
- bloods
- post void residual
4 times to use scope
- hematuria
- other assoc. Sx
- bladder CA risk
- not respnding to ther
2 spincters and how they’re controlled
- internal - smooth muscle - involuntary
2. external - striated - voluntatry
2 Tx for incontience post-prostatectomy
- artificial phincter
2. male sling
what is the effect of stroke
can cause detrusor overactivity
- still have good sphincter control
