Urinary Incontinence and Prolapse Flashcards
At what point does the bladder signal for voiding?
400ml full
What is the micturition reflex?
This is parasympathetics that supply the bladder sending signals to the spinal bladder center (S2,3). There are descending controls from the brain to prevent overactive detrusor muscle. When bladder reaches the right volume and distension then there is signal to void
What is meant by overflow incontinence?
This is incontinence due to obstruction of the bladder inhibiting micturition. There will be a large and palpable bladder with discomfort. Patients may also present with being wet at night
How is overflow incontinence treated?
Need to confirm by examination (will be uncomfortable, can’t get below it, dull percussion) then locate the obstruction. Catheterise to relieve the pressure and fix the obstruction
What is urge incontinence?
This is an increase in frequency but a decrease if urinary voiding volume due to an overactive detrusor muscle.
What can cause an overactive detrusor?
irritation within the bladder
lack of descending controls from the brain
What is used to diagnose urge incontinece?
Urodynamics - will have multiple spikes
What is used to treat urge incontinence?
Dietary adjustment, bladder retraining, antimuscurinics (oxybutynin) or beta-3-adrenergics, can use botox injections or surgery
What is stress incontinence?
This is incontinence due to increased abdominal pressure without the presence of detrusor contraction. It is mainly caused by childbirth causing damage to the perineum and urethra
usually brought on by coughing/laughing
How is stress incontinence diagnosed?

How is stress incontinence treated?
diet, pelvic floor exercised, (duloxetine) and surgery (can do minimally invasive taping procedure)

What examinations should be done for UI?
BMI, abdo (masses, bladder), vaginal (prolapse), PR (masses), cognitive impairment assessment
What investigations should be carried out for UI?
urinalysis, post void residual, urodynamics, cystoscopy, imaging
Oxybutynin and tolteride are examples of…
