Q

How do we examine for cystocele?

A

patient should empty their bladder and bowel before examination of a prolapse. When examining for pelvic organ prolapse, various positions may be attempted, including the dorsal and left lateral position.
Sim’s speculum is a U-shaped, single-bladed speculum that can be used to support the anterior or posterior vaginal wall while the other vaginal walls are examined. It is held on the anterior wall to examine for a rectocele, and the posterior wall for a cystocele
women can be asked to cough or “bear down” to assess the full descent of the prolapse.

Q

What is the normal anatomy of the pelvis?

A
  • Level 1 support:
  • Uterosacral ligaments - extend posteriorly from cervix / upper vagina to the sacral spine.
  • Level 2 support:
  • Arcus tendineus fasciae pelvis (ATFP) - runs from ischial spines to pubic tubercle, attaching to
    sheets of suspensory ‘slings’ of fascial tissue e.g. pubovesicocervical fascia.
  • Level 3 support:
  • Perineal body - fibromuscular mass, point of attachment for pelvic muscles.
  • Pubourethral ligaments.

Q

What is urinary continence and what are the two types?

A

Urinary incontinence refers to the loss of control of urination. There are two types of urinary incontinence, urge incontinence and stress incontinence

31
Q

What is urge incontinence and what is it caused by?

A

Urge incontinence is caused by overactivity of the detrusor muscle of the bladder. Urge incontinence is also known as overactive bladder

32
Q

What is the pathophysiology of urge incontinence?

A

○ Mechanism not fully understood - likely a combination of myopathy and
neuropathy.

Involuntary bladder contractions

Sphincter weakness

Overactive bladder

Stress urinary incontinence

33
Q

Typical description of urge incontinence

A

suddenly feeling the urge to pass urine, having to rush to the bathroom and not arriving before urination occurs

34
Q

What is the pelvic floor and what does it consist of?

A

pelvic floor consists of a sling of muscles that support the contents of the pelvic. There are three canals through the centre of the female pelvic floor: the urethral, vaginal and rectal canals. When the muscles of the pelvic floor are weak, the canals become lax, and the organs are poorly supported within the pelvis

35
Q

What is stress incontinence caused by?

A

weakness of the pelvic floor and sphincter muscles. This allows urine to leak at times of increased pressure on the bladder. The typical description of stress incontinence is urinary leakage when laughing, coughing or surprised.
Urinary loss during a period of raised intra-abdominal pressure, e.g coughing and sneezing

36
Q

What is the pathophysiology of stress incontinence?

A

○ Raised intra-abdominal pressure increases intra-vesical pressure.
○ IVP exceeds resistance of urethral sphincters leading to leakage.
○ This typically occurs due to downward movement of the internal sphincter
secondary to pelvic floor weakness (urethral hypermobility).

37
Q

What does stress incontinence involve?

A

Involuntary leakage

Cough
Laugh
Lifting
Exercise
Movement

Walking / running downhill
Intercourse
Stumble / choking / vomiting

38
Q

What is mixed

A

weakness of the pelvic floor and sphincter muscles. This allows urine to leak at times of increased pressure on the bladder. The typical description of stress incontinence is urinary leakage when laughing, coughing or surprised.

39
Q

What is the pathophysiology behind the different types of incontinence?

A

Sphincter Weakness: Stress Incontinence
Detrusor Overactivity: Overactive Bladder

(Mixed Incontinence = both)

Fistula
Neurological & Functional
Overflow & retention

40
Q

What is mixed incontinence?

A

Mixed incontinence refers to a combination of urge incontinence and stress incontinence. It is crucial to identify which of the two is having the more significant impact and address this first.

41
Q

What is overflow incontinence?

A

Overflow incontinence can occur when there is chronic urinary retention due to an obstruction to the outflow of urine

Chronic urinary retention results in an overflow of urine, and the incontinence occurs without the urge to pass urine

42
Q

What can cause overflow incontinence

A

with anticholinergic medications, fibroids, pelvic tumours and neurological conditions such as multiple sclerosis, diabetic neuropathy and spinal cord injuries.

43
Q

What is overflow incontinence more common in?

A

more common in men, and rare in women. Women with suspected overflow incontinence should be referred for urodynamic testing and specialist management

44
Q

What are the risk factors for urinary incontinence?

A

Increased age
Postmenopausal status
Increase BMI
Previous pregnancies and vaginal deliveries
Pelvic organ prolapse
Pelvic floor surgery
Neurological conditions, such as multiple sclerosis
Cognitive impairment and dementia
High parity

45
Q

What is the presentation of stress and urge incontinence?

A

● Stress incontinence - involuntary passage of urine during activities that raise
intra-abdominal pressure (sneezing, coughing etc.)
● Urge incontinence - involuntary passage of urine with associated urge to pass urine,
increased urinary frequency

46
Q

What are the investigations for urinary incontinence?

A

● First Line: urinalysis to rule out UTI, plus:
○ Bladder diary
○ Symptom questionnaire
● Second Line: urinary stress testing, e.g.
○ Cough stress test
○ Empty supine stress test

Urinalysis (MSU)
Frequency volume chart (FVC)
Residual urine measurement (RU)
Questionnaire (ePAQ)

47
Q

How do we measure residual urine measurement?

A
  • In & out catheter - CISC
  • Post surgical voiding dysfunction, post natal retention, neuropath
  • US
48

49
Q

How can a medical history differentiate between types of urinary incontinence?

A

urinary leakage with coughing or sneezing (stress incontinence), and incontinence due to a sudden urge to pass urine with loss of control on the way to the toilet (urge incontinence).

50
Q

What are the modifiable lifestyle factors that contribute to symptoms of urinary incontinence?

A

Caffeine consumption
Alcohol consumption
Medications
Body mass index (BMI)
Weight loss1
Smoking cessation2
Reduced caffeine intake3
Avoidance of straining and constipation4

51
Q

How do we assess the severity of urinary incontinence?

A
  • Frequency of urination
  • Frequency of incontinence
  • Nighttime urination
  • Use of pads and changes of clothing
52
Q

What should an examination of urinary incontinence examine for?

A

Assess pelvic tone
Pelvic organ prolapse
Atrophic vaginitis
Urethral diverticulum
Pelvic masses
During the examination, ask the patient to cough and watch for leakage from the urethra.

53
Q

how strength of the pelvic muscle contractions be examined?

A

During a bimanual examination by asking the woman to squeeze against the examining fingers - graded by the modified Oxford grading system

54
Q

modified Oxford grading system

A

0: No contraction
1: Faint contraction
2: Weak contraction
3: Moderate contraction with some resistance
4: Good contraction with resistance
5: Strong contraction, a firm squeeze and drawing inwards

55
Q

How can we investigate urinary incontinence?

A

A bladder diary should be completed, tracking fluid intake and episodes of urination and incontinence over at least three days. There should be a mix of work and leisure days.

Urine dipstick testing should be performed to assess for infection, microscopic haematuria and other pathology.

Post-void residual bladder volume should be measured using a bladder scan to assess for incomplete emptying.

Urodynamic testing can be used to investigate patients with urge incontinence not responding to first-line medical treatments, difficulties urinating, urinary retention, previous surgery or an unclear diagnosis. It is not always required where the diagnosis is possible based on the history and examination.

56
Q

What are urodynamic tests used for and what needs to be stopped when doing one?

A

Urodynamic tests are a way of objectively assessing the presence and severity of urinary symptoms. Patients need to stop taking any anticholinergic and bladder related medications around five days before the tests.

57
Q

What do urodynamic tests measure?

A

Cystometry measures the detrusor muscle contraction and pressure
Uroflowmetry measures the flow rate
Leak point pressure is the point at which the bladder pressure results in leakage of urine. The patient is asked to cough, move or jump when the bladder is filled to various capacities. This assesses for stress incontinence.
Post-void residual bladder volume tests for incomplete emptying of the bladder
Video urodynamic testing involves filling the bladder with contrast and taking xray images as the bladder is emptied. Theses are only performed where necessary and not a routine part of urodynamic testing.

58
Q

Management of stress incontinence

A

○ First Line: pelvic floor exercises (8 contractions x3 per day) + lifestyle measures
e.g. reducing caffeine, weight loss, moderate fluid intake.
○ Second Line: (for some patients) - pseudoephedrine, topical oestrogen
○ Third Line: surgery such as retropubic colposuspension
Supervised pelvic floor exercises for at least three months before considering surgery
Surgery
Duloxetine is an SNRI antidepressant used second line where surgery is less preferred
Pelvic floor exercises are used to strengthen the muscles of the pelvic floor. They increase the tone and improve the support for the bladder and bowel.

59
Q

What are the surgical options to treat stress incontinence include?

A
  • Tension-free vaginal tape (TVT) procedures involve a mesh sling looped under the urethra and up behind the pubic symphysis to the abdominal wall. This supports the urethra, reducing stress incontinence.
  • Autologous sling procedures work similarly to TVT procedures but a strip of fascia from the patient’s abdominal wall is used rather than tape
  • Colposuspension involves stitches connecting the anterior vaginal wall and the pubic symphysis, around the urethra, pulling the vaginal wall forwards and adding support to the urethra
    Intramural urethral bulking involves injections around the urethra to reduce the diameter and add support
60
Q

What is the management of Urge incontinence?

A

○ First Line: bladder training
○ Second Line: anticholinergic e.g. oxybutynin, solifenacin
○ Third Line: mirabegron (beta-3 agonist)
○ Plus: topical oestrogen if atrophic vaginitis present

61
Q

What are some SE of anticholinergic medications?

A
