Urinary incontinence Flashcards
continence
ability to consciously control over micturition and defecation
incontinence
involuntary leakage of urine, feces or both
factors to ensure continence
intact bladder and urethra
intact nervous structure
proper bladder position
able to control intra abdominal pressure on bladder
normal bladder capacity and dimension
being in mentally and physically able situations
Pressure transmission
When bladder pressure exceeds urethra pressure the resting tone of the urethra muscle maintain a significant portion of the pressure
what determine if leakage will occur
Strength of resting pressure
increase of pressure during coughing
Classes of incontinence
overflow
stress urinary
urge urinary
mixed
extraurethra
reflex
nocturnal
giggle
coital
overflow
bladder outlet destruction
a contractile bladder
frequency or continuous dripping
can be caused by diabetes, SCI
urethra blockage
Stress urinary incontinence
no detrusor contraction
during physical movement
insufficient urethra
bladder neck hypermobility
internal sphincter failure
PFM weakness
increased abdominal pressure
urge UI
leakage with sudden urine urge
overactive detrusor
hypersensitive bladder
determined by urodynamic tests
Extraurethra incontinence
exit of urine from different way
opening between urethra, bladder and vagina
disorder of pelvic structure
treatment with reconstructive surgery
Reflex incontinence
due to suppression of voiding center
detrusor hyperactivity
giggle
rare
adolescent girls
coital
just after coitus
if after orgasm is due to detrusor instability
vagina and urethra are adjacent strucures
