Incontinence & Prolapse Flashcards
What structures does urinary continence depend on?
- bladder neck support
- external urethral sphincter
- smooth muscle in urethral wall
- compresor urethrae
- levator ani
What are the risk factors for urinary incontinence?
Women (pregnancy, childbirth, menopause) Age (loss of muscle strength) Obesity (increased pressure) Smoking (chronic cough) Other diseases - diabetes, kidney disease
Name three types of incontinence
Stress
Urge
Overflow
What examinations should be done in an incontinent patient?
Abdomen
Pelvis/perineum
Rectal
Neurological
What investigations should be done in a patient with suspected incontinence?
Stress test
Post void residual (normal 10-80, abnormal >100-150)
Urine analysis
Bladder diary
What lifestyle measures can help with incontinence?
Bladder retraining Fluid intake Weight loss Pelvic Floor exercises Bladder drill
State the drugs used in urinary incontinence
Antimuscarinic agents
Beta 3 agonists e.g mirabegron
Duloxetine
How do antimuscarinic drugs help incontinence?
Prevent involuntary contraction of detrusor muscle
What are the side effects of antimuscarinic drugs?
Dry mouth
Constipation
Nausea
Headache
How does Mirabegron work?
Relaxes bladder smooth muscle through activation of beta 3 adrenoreceptors to increase voiding interval and inhibit spontaneous contractions
What is uroflowmetry?
Measurement of volume of urine expelled from the bladder each second (ml)
What are the indications for uroflowmetry?
Hesitancy, voiding difficulty, neuropathy, history of urine retention, post-op follow up
What does cystometry measure?
Pressure/volume of the bladder at different stages
- filing
- provocation
- voiding
Describe the conservative management of stress incontinence
Lifestyle, physio, drugs - duloxetine, pads, pessaries
Describe the surgical management of stress incontinence
Low tension tape, intra-urethral injection, artificial sphincter, colposuspension, autologous fascial sling
