VOIDING CYCLE:
storage and voiding phase
storage phase when urine is stored = around 300-400mls and 0 pressure without sensation of distension (3-4 hours) until contractile capacity is rached and pressure inc and associated with sesnation of distension
voiding phase: relaxation of external sphincter which relaxes, bladder contracts and empties under voluntary control
26
4 catergoris of incontinence
4 catergories include:
1. stress
2. urge
3. mixed
4. other - if no features of stress or urge consider uncommon such as fistula or overflow incontience
27
stress incontinence + pathogenesis
urine flow increased due to activity e.g. laughing/coughing
resitance in outlet reduced and overcome with inc intrabdominal pressure
28
urge incontinence
loss of urine due overwhelming urge to void during storage phase
29
etiology of stress incontience
middle aged women:
pelvic floor age related atrophy due to childbirth, chronic cough, chronic constipation, smoking
OTHERS:
injury during surgery
males (iatrogenic during prostate surgery)
Neurological: spina bifida /spinal injury - due to paralysis of sphincter and bladder neck
30
investgations stress incotinence
urodynamic studies (only if surgery contemplated
31
Treatment stress inctontinece

33
Fistula: is this rare or common cause of incontinence
rare
34
most common fistula presenting as incotinince?
vestigovaginal fistula
35
vestigovaginal fistula presentation
dribbling incontinence
36
urge incontinence pathogenesis
increases in bladder pressure during storage phase, which causes unstable contractions of bladder and loss of compliance (inapporpriate level of pressure for amount of urine)
37
What is the etiology in neurologically normal patients for urge incontinence
Idiopathic bladder instability (common)
interstitial cystitis
radiation injury
carcinoma in situ (TCC)
38
What is the etiology in neurologically abnormal patients for urge incontinence
poor compliance of bladder and instability due to:
UMN spinal cord injury
Parkinsons
Multiple Sclerosis
Stroke (CVA)
39
Investigations for urge incontinence
1. MSU to exclude infection
2. Post void residual to exclude retention
3. cytology if patient over 60 + haematuria
4. renal US if upper tract reflux

40
Treatment for urge incontinence

Anticholinergics sucha s oxybutin
Botox
Bladder augmentation
41
If men have urge incontince day and night what needs to be done and why?
Vesicouteric junction - if pressures are high enough to overcome a high resistance male outlet, they may be high enough to overcome vesicoreteric junction)
42
Mixed incontience what is this ?
who is this more common in
mixed features of urge and stress incontinence:
more common in women
43
Other incontinence
If patients do not describe either stress or urge incontinence, they usually describe constant dribbling,
or incontinence without sensation ( just find myself wet.) This may be a reflection of severe stress
incontinence when any slight movement results in leakage. Urodynamics is required to sort this out.
Alternative diagnoses to be considered are:
overflow incontinence or fistula
44
What is overflow incontinence ?
overflow of urine with patients with chronic retention
45
how does overflow inctonence present?

with peristalsis has been obliterated
```
52
overflow incotninence surgery
catheterisation + TURP Males + surgery females(vaginal sling
53
Paediatric: Phimosis What is this?
inability to retract the foreskin (prepuce) covering the head (glans) of the penis - can be pathological or physiological)
54
What is phimosis most common reason for ?
circumscicion Although recurrent balanitis is also indication (inflammation of the glans)

NO
58
what is difference between non retractile forskin and phimosis ?
non retractile - ballons with urination however on examination urethral meatus is visible and with time will open and allow foreskin to retract normally. Phimosis (true) is where physically cannot usually due to scarring or balantitis
59
true phimosis treatment ?
| what is the two indications
circumscision
