Urology- Incontinence Flashcards
Causes of incontinence: urethral obstruction
BPH, strictures, stenosis
Causes of incontinence: impair bladder contraction
DM, MS, spinal injuries, detrusor hyperactivity
Causes of incontinence: incompetent sphincter
stress incontinence, cystocele
Causes of incontinence: bladder inflammation
UTI, interstitial cystitis
Causes of incontinence: bladder stones
obstruction, metabolic disease, UTI
Causes of incontinence: malignancy
bladder cancer, carcinoma in situ, invasive cancer
Urge incontinence/OAB
involuntary leakage of urine, involuntary contraction of bladder, detrusor hyperreflexia
Stress incontinence
Involuntary leakage with “stress”
cystitis, stones, tumor, neurologic
Overflow incontinence
leaking urine throughout the day
“Weight of urine”
Meds for OAB
Smooth muscle relaxants
Beta-3 adrenergic receptor agonists
Smooth muscle relaxants MoA
Antimuscarinic, “atropine”-like
Smooth muscle relaxants drugs
Oxybutinin, tolterodine, trospium, darifenacin, solifenacin, fesoterodine
Most effective smooth muscle relaxants
Darifenacin, solifenacin, ER tolterodine –> least likely to cause side effects!
Beta-3 adrenergic receptor agonists MoA
Detrusor muscle relaxation –> works on the storage phase
Beta-3 adrenergic receptor agonist drugs
