Q

What causes stress urinary incontinence?

A

-Urethral hypermobility (found in women with impaired pelvic floor support)

Q

Surgical management for stress urinary incontinence?

A
  • Bulkamid
    -Synthetic substance is injected into the walls of urethra to increase its size to allow it to remain closed under pressure
  • Fascial slings
    -A sling is made using the rectus sheath and placed behind the urethra to support it
  • Colposuspension
    -Lifting up the tissue around the neck of the bladder, and suspending it to the ileopectineal ligament using non absorbable synthetic stitches

Q

Cause of urgency urinary incontinence?

A

-Caused by detrusor instability or hyperreflexia leading to involuntary detrusor contraction

-This may be idiopathic or secondary to neurological problems such as stroke, Parkinson’s disease, multiple sclerosis, dementia or spinal cord injury

16
Q

conservative management- urgency urinary incontinence/ over active bladder

A

Bladder retraining= first line

-Fluid management (drinking enough fluids)
-Weight management
-Eliminating caffeine, fizzy drinks, alcohol

17
Q

medical management- urgency urinary incontinence/ over active bladder

A

-Vaginal oestrogen
-Anticholinergics (tolterodine, soliphenacin)
-β3-adrenoceptor agonist (mirabegron)
-Desmopressin (nocturia) (not used as commonly)

18
Q

examples of anticholinergics used in medical mangement of urinary incontinence/ overactive bladder?

A

Tolterodine
Soliphenacin

19
Q

how do anticholinergics work?

A

Anticholinergics inhibit involuntary contraction - stops detrusor from contracting inappropriately by blocking the antimuscarinic receptors

20
Q

would you give someone with cognitive decline an anticholinergic (tolterodine, soliphnocin)

A

no- as they can increase cognitive decline

21
Q

how does Mirabegron (B3- adrenoceptor agonist) work to help urinary incontincen?

A

-inreases relaxation of detrusor by activating the Mg receptors

22
Q

surgical management- urgency urinary incontinence/ over active bladder

A

used if medical management fails

First line= Botox
-Percutaneous posterior tibial nerve stimulation (after botox failed)
-Augmentation cytoplasty (last resort)

23
Q

what is bulkamid?

A

surgical treatment for stress urinary incontinence

-inject synthetic substance into walls of urethra to increase its size to allow it to remain closed under pressure

24
Q

what are fascial slings?

A

surgical treatment for stress urinary incontinence

rectus sheath is used to be made into a sling and put behind the urethra to support it

25
Q

what is colpususpension?

A

surgical treatment for stress urinary incontinence

lifting up tissue around the neck of the bladder and suspending it from the ilepectal ligament to support it

26
Q

what neurological problems could cause urgency urinary incontinence AKA overactive bladder syndrome?

A

-Parkinsons
-MS
-stroke
-Dementia
-Spinal cord degeneration

27
Q

what investigation is done if first line treatment doesnt work for urinary incontinence?

A

urodynamic testing

(1st line= bladder training for atleast 6 weeks)

28
Q

SE of botox treatment for urgency urinary incontinence

A

could paralyse detrusor muscles and so could need catheter

29
Q

what is mixed urinary incontinence?

A

involuntary leakage of urine associated with both urgency and exertion, effort, sneezing or coughing

30
Q

causes of mixed urinary incontinence?

A

Can be caused by chronic urinary retention or a blockage to the outflow of urine

Causes:
-congenital structural abnormalities
-Pelvic mass (fibroids, tumours)
-Anticholinergic medication
-Neurological conditions: MS, diabetic neuropathy and spinal cord injuries

31
Q

A 34-year-old woman from Chad presents with continuous dribbling incontinence after having her 2nd child. Apart from prolonged labour the woman denies any complications related to her pregnancies. She is normally fit and well.

What is the most likely diagnosis?

A

vesico vaginal fistula

32
Q

presentation- vesico vaginal fistula?

A

Continuous dribble incontinence after prolonged labour or labour in developing world

33
Q

investigations- vesico vaginal fistula?

A

Urinary dye studies

34
Q

who should oxybutin be avoided in and why?

A

avoid in elderly patients
-increases chance of falls
