Q

What are some features of pelvic floor muscle exercises for urinary incontinence?

A

Effective for stress and mixed incontinence

Minimum of 3 months supervised trial with physio

20
Q

What are some features of using antimuscarinics for urinary incontinence?

A

Side effects = dry mouth, constipation, blurred vision and somnolence
Examples = solifenacin (1st line), tolterodine, oxybutin (non-selective)

21
Q

What are some of the effects that antimuscarinics can have in urinary incontinence?

A

Reduce intravesical pressure and increase compliance
Raise volume threshold for urination
Reduce uninhibited contractions

22
Q

What is the most commonly used therapy for OAB after lifestyle changes?

A

Antimuscarinics

23
Q

What are some other medications used to treat urinary incontinence?

A

B3 adrenoceptor agonists = mirabegron

24
Q

What are some features of mirabegron as a treatment for urinary incontinence?

A

Selective agonist = relaxes bladder smooth muscle

Increases voiding interval and inhibits spontaneous bladder contractions during filling

25
Q

What are some features of percutaneous posterior tibial nerve stimulation as a treatment for urinary incontinence?

A

12 weeks of treatment = 30mins once a week

Improves OAB by 30-40%

26
Q

What is uroflowmetry?

A

Measurement of volume of urine expelled from bladder each second

27
Q

What are the indications for uroflowmetry?

A

Hesitancy, voiding difficulty, neuropathy, history of urine retention, post-operative follow up

28
Q

What does the measurement of urine flow rate allow?

A

Measurement of peak flow (should be 20-60ml), mean flow and voided volume

29
Q

What occurs during cystometry?

A

Pressure/volume relationship of bladder is measured during filling, provocation and during voiding

30
Q

What are mutlichannel urodynamics used for?

A

Uncertain diagnosis, non-response to treatment and possibly prior to surgery

31
Q

How is overflow incontinence managed and what causes it?

A

Obstruction of urethra and poor contractile bladder muscle = must find out post voidal residual and stop anticholinergics immediately

32
Q

What are some conservative treatment options for stress incontinence?

A

Lose weight, stop smoking, avoid caffeine and excessive fluid intake, pelvic floor retraining, biofeedback, electrical stimulation, pessaries, incontinence pads

33
Q

What medication can be used to treat stress incontinence?

A

Duloxetine = combined noradrenaline and SSR inhibitor

34
Q

What are the surgical options for treating stress incontinence?

A

Low tension vaginal tape, intra-urethral injection, artificial sphincters, colposuspension, autologous fascial sling

35
Q

What are the three compartments of the vagina where prolapse can occur?

A 
Anterior = cystocele
Middle/apical = vaginal vault prolapse/enterocele
Posterior = rectocele
36
Q

How common are pelvic organ prolapses?

A

Up to 50% of parous women = 10-20% symptomatic

11% lifetime risk of surgery

37
Q

What are the classifications of uterovaginal prolapses?

A

1st degree = in vagina
2nd degree = at interiotus
3rd degree = outside vagina
Procidentia = entirely outside vagina

38
Q

What are the symptoms of an anterior or middle/apical prolapse?

A

Bulging, pressure, difficulty voiding, incomplete emptying, splinting vaginal wall, pain during sex, difficulty inserting tampon

39
Q

What are the symptoms of posterior prolapse?

A

Bulging, pressure, difficulty defaecating, incomplete defaecation, splinting vaginal wall or perineum, difficulty inserting tampon

40
Q

What occurs in a complete eversion prolapse?

A

Uterine procidentia, complete uterine prolapse

41
Q

How is the Pelvic Organ Prolapse Quantification System (POP-Q) used?

A

Patient asked to strain = 6 specific sites evaluated, 3 sites evaluated at rest
Measure at each site (cm) in relation to hymenal ring

42
Q

How is the POP-Q scored?

A

If site is above hymen its assigned negative number

If site is below hymen its assigned positive number

43
Q

What are the risk factors for pelvic organ prolapse?

A

Aging, pelvic surgery, menopause, loss of muscle tone, multiple vaginal births, obesity, chronic cough or constipation, uterine fibroids, family history, connective tissue disorder (e.g Marfan’s)

44
Q

What are the conservative management options for pelvic organ prolapse?

A

Avoid heavy lifting, weight loss, stop smoking, reduce constipation, vaginal oestrogens (if symptomatic atrophic vaginitis)

45
Q

What physical exercises can be given to treat pelvic organ prolapse?

A

4-6 months of pelvic floor muscle exercises

46
Q

What patients are given a pessary to treat pelvic organ prolapse?

A

Unfit for surgery, relief of symptoms while awaiting surgery, pregnant/planning future pregnancy, diagnostic test, patient request

47
Q

What are the surgical options for treating pelvic organ prolapse?

A

Vaginal hysterectomy or sacrospinous fixation
Manchester repair = cervix amputated, uterosacral ligaments shortened
Abdominal/laparoscopic sacrocolpopexy or colpocleisis
Mesh techniques = not since 2014 in Scotland
