Q

What cortical activity is involved in the filling of the bladder?

A

Cortical activity activates a reciprocal guarding reflex by Rhabdosphincter contraction; increase sphincter contraction & resistance.
-Activates symptathetic pathway
-Reciprocal inhibition of the parasympathetic pathway
M
-Mediates contraction of bladder base and proximal urethra

Q

What voiding symptoms may a patient present with?

A
  • Straining to void
  • Interrupted flow
  • Recurrent UTI
25
What prolapse symptoms may a patient present with?
- Vaginal lump | - Dragging sensation in vagina
26
What bowel symptoms may a patient present with?
- Anal incontinence - Constipation - Faecal evacuation - Dysfunction - IBS
27
What investigations should be carried out?
- QoL assessment - 3 day urinary diary - Urinalysis (MSSU an dipstick) - Post voiding residual volume assessment (usually by bladder scanning) only If symptoms of voiding difficulties. - Urodynamics: ONLY indicated if surgical treatment is contemplated.
28
What should be noted in a 3 day urinary diary?
- Fluid intake: Quantity & Quality - Urine Out-Put (exclude Nocturnal Polyuria) - Daytime Frequency, - Nocturia - Average voided volume.
29
What examination should a woman presenting with UI have?
- General - Abdominal - Neurological - Gynaecological - Pelvic floor assessment (Oxford scale)
30
What should be looked at on examination of a women presenting with UI?
- Prolapse - Stress incontinence - Uro-genital atrophy changes - Pelvic mass (space occupying leasion) - Pelvic floor tone, strength, awareness
31
What are the principles of management?
- Lifestyle changes - Medical treatments - Physiotherapy - Surgery
32
When does stress incontinence occur?
When intra-abdominal pressure exceeds urethral pressure resulting in leakage
33
What is urethral closure increased by?
- Pelvic floor muscle training - Surgery - Pharmacological agents
34
What lifestyle changes should be advised as part of management?
- Stop smoking - Lose weight - Eat more healthily to avoid constipation - Stop drinking alcohol and caffeine
35
Who should receive conservative treatment for UI?
Everyone unless - Patient doesn't wish it - Previously failed - No facilities
36
What does pelvic floor muscle lead to?
- Reinforcement of cortical awareness of muscle groups - Hypertrophy of existing muscle fibres - General increase in muscle tone and strength
37
What is the effectiveness of pelvic floor muscle training?
60-70% cure or significant improvement
38
What is the only drug licensed for the treatment of moderate to sever SUI?
Duloxetine
39
Who should receive duloxetine?
Primary care -If PFMT has failed or would be enhanced by duloxetine Secondary care - Does not wish surgery - Not fir for surgery - After failure surgery - When the patients family is not complete
40
What anatomical defect is associated with SUI and UUI?
- Defect in the anterior vaginal wall and pubo-urethral ligament - Urethral/bladder neck closure dysfunction and USI

What can suburethral hammock laxity result in?
Stimulation of bladder neck stretch receptors provoking a premature micturition reflex and urgency incontinence

Overactive bladder syndrome
A symptom complex usually, but not always, related to urodynamically demonstrable detrusor overactivity (DO)
46
What are the defining symptoms of overactive bladder syndrome?
- Urgency (with/without UUI) - Frequency - Nocturia

Urgency
The complaint of a sudden, compelling desire to pass urine that is difficult to defer
48
Frequency
Usually accompanies urgency with or without urge incontinence and is the complaint by the patient who considers that he/she voids too often by day

Nocturia
Usually accompanies urgency with or without urge incontinence and is the complaint that the individual has to wake at night one or more times to void

- Advanced age - Diabetes - UTI - Smoking
51
How does the prevalence of OAB change with age?

52
What are the principles of management for OAB?
- Treat symptoms - No immediate cure - Multidisciplinary approach - Requires dedicated team
53
How can OAB be treated conservatively?
Life style interventions: - Normalise fluid intake - Reduce caffeine, Fizzy drinks, Chocolate - Stop Smoking - Weight loss Bladder training programme: -Timed voiding with gradually increasing intervals - Continence nurse
54
What is the principle of bladder retraining?
The re-establishment of cortical control over detrusor function and voiding
55
How is bladder retraining achieved?
Timed bladder emptying programme
56
What pharmacological treatment is there for OAB?
``` -Antimuscarinic (Oral): -Solifenacin (Vesicare 5-10mg ) -Fesoteridine (Toviaz 4-8 mg) -Trospium Chloride (60mg XL) -Darifencain (Emselex 7.5-15 mg ) – Constipation; FI -Lyrinel XL (10-20 mg ) -Oxybutinin (5-10 mg/ tds) (Transdermal:) -Kentera Patches ``` Tri-cyclic antidepressants: -Imipramine
57
What are the recent advances for UI management?
- Botox | - Neuromodulation
58
What are the features of botox treatment?
- Botulinum Toxin (A&B) - NDO/ IDO - 200-300 Unit (12U/Kg) - Cystoscopy/ GA - 75% Cure & Significant Improvement - Effects last for 6-9 months - CISC
59
What are the features of neuromodulation treatment?
- Needle stimulation (S2-4) - Reflex Inhibition to the Detrusor muscle - Cheap - Minimally invasive - 70% improvement in Refractory OAB$
