Q

How could you approach the question of incontinence with a patient without leading to their embarrassment (2)?

A

“Do you have any problems with your bladder or bowel?”

“Do you ever pass urine or faeces involuntarily?”

Q

How is continence of the bladder maintained?

A

Continence is maintained by the co-ordinated interaction of the bladder, urethra, pelvic floor muscles and the nervous system

The bladder is a low pressure – high volume system; the pressure increases slowly as the bladder fills (rate 0.5-5ml /hr)

Continence is maintained so long as the urethral pressure exceeds the bladder pressure

Q

What is the process of micturition?

A

The voluntary relaxation of the striated muscle around the urethra; this reduces urethral pressure

This is followed by a corresponding increase in bladder pressure as a consequence of detrusor contraction

Q

What are the physiological control mechanisms of micturition?

A
  1. The micturition cycle involves both the somatic (voluntary) and autonomic (sympathetic and parasympathetic) nervous systems
  2. The frontal cortex provides voluntary control.
  3. The pontine micturition centre (midbrain) co-ordinates detrusor contraction with urethral relaxation.
  4. Bladder contraction is mediated by the parasympathetic system.
  5. These parasympathetic fibres, along with those responsible for somatic control (pudendal nerve), originate from the sacral plexus (S2 to S4).
  6. Excitation of the parasympathetic nerves stimulates the release of acetylcholine, which acts on muscarinic receptors (there are 5 subsets of muscarinic receptors with subset M3 being primarily responsible for bladder contraction) to cause detrusor contraction.

Q

What are the physiological control mechanisms of bladder filling?

A
  1. Bladder filling is mediated by the sympathetic system.
  2. Sympathetic nerves arise from T11 to L2 and innervate the smooth muscle of the bladder neck and proximal urethra causing contraction, allowing the bladder to fill.
  3. Excitation of the pudendal nerve causes contraction of the external urethral sphincter, allowing voluntary control.
  4. Voiding therefore depends on parasympathetic activity, with opening of the bladder neck, which is involuntary, followed by voluntary relaxation of the external urethral sphincter.

Q

When should you screen an older person for incontinence? How would you screen for it?

A
  1. At any consultation, include a screening q about continence issues i.e. “do you have any problems with either your bladder or bowels?
  2. If the answer is positive, a full assessment should be offered.
  3. Validated screening questionnaires are also available for selected patients, e.g. the Bladder Control Self Assessment Questionaire (B-SAQ)

Q

What imaging can you do for incontinence?
1 essential
and 4 non-essential

A

Essential 1st line
-Post void bladder scan. Performed to rule out chronic retention of urine

Only if there are specific indications:

  • USS Abdo – requested if renal failure to evaluate kidney size and look for signs of obstructive uropathy.
  • CT urography – requested if considering renal stones.
  • CT abdo – to exclude abdominal or pelvic masses if these are suspected.
  • Intravenous Urogram (IVU) – useful if renal stones are suspected. However this has largely been superceded by CT urography in most centres.

Q

How does uroflowmetry work?

A

Urine flow rate and volume is measured using a flowmeter.

Patients are left in private to void normally (either sitting or standing)

There are different kinds of flowmeter but a common one is the rotating disc – the urine flows onto a rotating disc in the commode and this increases the inertia of the disc which can be measured and translated by the computer software into a flow rate.

Q

What techniques does US cystodynamogram use?

What do they measure (3)?

A

Combines the flowmetry with pre and post void bladder scanning

Measures functional bladder capacity, flow rate and post void bladder volume (residual)

41
Q

What does cystometry measure (3)?

A
  1. bladder pressure, sensation
  2. capacity
  3. compliance during filling and voiding i.e. bladder pressure studies.
42
Q

How does cystometry work (3)?

A
  1. The bladder is filled with saline at room temperature via a small bore urethral catheter which is passed along with a pressure transducer.
  2. A further pressure transducer is placed in the rectum.
  3. Pressure recordings are measured as the bladder is filled
43
Q

What techniques do videourodynamic studies use?

What do they measure?

A

Combination of cystometry and radiographic screening, so that both pressure and visual information is obtained

44
Q

What are the advantages of ambulatory urodynamics over conventional cystometry?

A

The non-physiological nature of conventional cystometry (i.e. the faster filling of the bladder) means abnormalities may be missed

Ambulatory urodynamics may overcome some of these limitations because it measures physiological filling and pressures during a patients usual daily routine

45
Q

How does ambulatory urodynamics work?

A

It uses the same transducer catheters as conventional urodynamics but connects them to a small “walkman-size” device and also uses electronic continence pads to detect leakage around the catheter

46
Q

What is the mneumonic for diagnosing potentially transient reversible causes of incontinence?

A

DIAPPERS

D - delirium
I - infection
A - atrophy (vaginal)
P - pharmacological
P - psychological
E - excess urine output
R - restricted mobility
S - stool impaction
47
Q

How does delirium cause incontinence?

A

Patient’s who have an acute confusional state often develop urinary incontinence, especially if the delirium is caused by a urinary tract infection.

48
Q

How do infections cause incontinence?

A

UTIs cause irritability of the bladder

49
Q

How can vaginal atrophy be managed?

A

Topical oestrogens

-prevent recurrent UTIs, and improve urgency and frequency symptoms. They do not improve incontinence per se

50
Q

What are 2 psychological causes of urinary incontinence?

A

Depression and dementia

51
Q

A
  1. The bladder outlet is weaker due to a shorter urethra and lack of prostate
  2. Childbirth increases risk esp with:
    -C section
    -Vaginal delivery
    -Forceps delivery
    (Damage can be a combo of ligament and nerve damage)
  3. Obesity - causes increased strain and weakening of the pelvic floor
  4. Vaginal atrophy

Q

What are 4 things that can be advised in Patient Education , in the management of SUI?

A
  1. Smoking cessation
  2. Weight reduction
  3. Managing constipation
  4. Reducing alcohol and caffeine
71
Q

What is a medical management of SUI?

A

Duloxetine (SNRI) - limited evidence and no longer recommended by NICE as 1st or 2nd line treatment

72
Q

What is the MDT and non-pharmacological treatment of SUI (4)?

A
  1. Community continence advisor
    - Continence advisor may assess patients in their own home and give advice and equipment.
    - Both continence advisors and physiotherapists can offer advice regarding pelvic floor exercises.
  2. Pelvic floor exercises - physiotherapist
  3. Vaginal cones
    -Designed to improve awareness of the pelvic musculature.
    The woman has to contract her pelvic floor muscles in order to keep the vaginal cone in position.
    -As the muscle strength improves, cones of increasing weight can be used
  4. Pudendal nerve stimulation
    -If a woman’s initial pelvic floor contraction is weak, this device can be used.
    The strength of stimulation can be altered as the muscle strength improves
73
Q

What are vaginal cones?

A

Vaginal cones are small weights that can be placed in your vagina to help you train your pelvic floor muscles. Used to treat SUI

74
Q

What are 3 surgical procedures that can be done for SUI?

A
  1. Mid-urethral sling insertion -(tension free vaginal tape, or TVT) provides support under the urethra.
  2. Colposuspension is a much more invasive operation although is useful if a patient has an associated cystocele.
  3. Injecting of bulking agents (e.g. silicone) into the urethra can also be performed although the success rates are much lower and therefore normally only an option in women not suitable for TVT or major surgery.
75
Q

What are 5 causes of pelvic floor muscle weakness?

A
  1. Childbirth
  2. Obesity
  3. Chronic cough
  4. Post pelvic surgery
  5. Post menopausal
76
Q

What is the patient education management of overactive bladder (OAB) (4)?

-can be with or without urgency
-primary or
-secondary to:
bph, neurological e.g. MS and PD

A
  1. Smoking cessation
  2. Weight reduction
  3. Manage constipation
  4. Reduce caffeine and alcohol intake (switch to decaff)
  5. Reduce fluid intake, especially in the evening
    (advise no drinks after 8pm)

(urinary freq and nocturia) - bladder only gest half full and sends signal to spinal cord that you need to urinate, so you go more frequently.

77
Q

What is the medical management of overactive bladder (OAB) (4)?

A
  1. Antimuscarinic drugs - mainstay of treatment
    - They act on the M3 receptors on the detrusor muscle to reduce contraction
    - oxybutynin
    - tolterodine
  2. Beta-3-adrenoceptor agonists (Mirabegron)
    - If there are contraindications, intolerable side effects or poor efficacy to antimuscarinics
    - Beta-3-adrenoceptors cause the bladder to relax, which helps it to fill and also to store urine.
  3. Intravaginal Oestrogens
    - NICE recommend their use for women who have vaginal atrophy and symptoms of overactive bladder
  4. Botulinum Toxin
    - This can be injected into the detrusor muscle via cystoscopy.
    - It inhibits neurotransmitter release thereby decreasing contractility
78
Q

What is the MDT and non-pharmacological treatment of OAB (3)?

A
  1. Community continence advisor
    - Can assess patients in their own homes and offer advice and information regarding urinary incontinence
  2. Pelvic Floor Exercises
  3. Behavioural Therapy
    - Involves bladder retraining
    - A patient increases the interval between first desire to void and actual voiding
