bladder dysfunction

Question 1

Urinary incontinence

-gender difs

Answer 1

Involuntary leakage of urine
-more prevalent with older adults (women more than men) but not a natural consequence of aging

Gender difs

• Men: common with BPH or prostate cancer; overflow incontinence from urinary retention
• Women: stress and urge incontinence

Question 2

Etiology and Pathophysiology of UI

Answer 2

Bladder pressure greater than urethral closure pressure
-interference with bladder or sphincter control

DRIP
D = delerium, dehydration, depression
R = restricted mobility, rectal impation
I = infection, inflammation, impaction
P = polyuria, polypharmacy

Question 3

Urinary Retention

Answer 3

Inability to empty bladder with voiding or the accummulation of urine bc of inability to void
-associated with leakage or post void dribbling = overflow UI

Acute urinary retention = inability to pass urine = med emergency

Chronic urinary retention = incomplete emptying despite urination

• Post void Residual is normally 50-75 mL
• –more than 100 mL = repeat or further evals with UTIs
• – more than 200 mL = further evaluation

Question 4

Etiology and pathophysiology of urinary retention

Answer 4

Bladder outlet obstruction: can’t empty
-men = enlarged prostate

Deficient detrusor contraction - muscle can’t contract with enough force to empty bladder
-neurologic diseases involving sacral 2,3, and 4; diabetes, overdistention; chronic alc use; and anticholinergic drugs
