Q

bladder storage symptoms

A
  • Increased daytime urinary frequency: Complaint that micturition occurs more frequently during waking hours than previously deemed normal by the woman.
  • Nocturia: Complaint of interruption of sleep one or more times because of the need to micturate. Each void is preceded and followed by sleep.
  • Urgency: Complaint of a sudden, compelling desire to pass urine which is difficult to defer.
  • Overactive bladder (OAB, Urgency) syndrome: Urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence, in the absence of urinary tract infection (UTI) or other obvious pathology.

Q

sensory symptoms - bladder filling

A

A departure from normal sensation or function, experienced by the woman during bladder filling. Normally, the individual is aware of increasing sensation with bladder filling up to a strong desire to void.

  • Increased bladder sensation: Complaint that the desire to void during bladder filling occurs earlier or is more persistent to that previous experienced. N.B.: This differs from urgency by the fact that micturition can be postponed despite the desire to void.
  • Reduced bladder sensation: Complaint that the definite desire to void occurs later to that previously experienced despite an awareness that the bladder is filling.
  • Absent bladder sensation: Complaint of both the absence of the sensation of bladder filling and a definite desire to void.

Q

voiding & post-micturition symptoms

A

SSSPPIN HUFD

A departure from normal sensation or function, experienced by the woman during or following the act of micturition.

  • Hesitancy: Complaint of a delay in initiating micturition.
  • Slow stream: Complaint of a urinary stream perceived as slower compared to previous performance or in comparison with others.
  • Intermittency: Complaint of urine flow that stops and starts on one or more occasions during voiding.
  • Straining to void: Complaint of the need to make an intensive effort (by abdominal straining, Valsalva or suprapubic pressure) to either initiate, maintain, or improve the urinary stream.
  • Spraying (splitting) of urinary stream: Complaint that the urine passage is a spray or split rather than a single discrete stream.
  • Feeling of incomplete (bladder) emptying: Complaint that the bladder does not feel empty after micturition.
  • Need to immediately re-void: Complaint that further micturition is necessary soon after passing urine.
  • Post micturition leakage: Complaint of a further involuntary passage of urine following the completion of micturition.
  • Position-dependent micturition: (NEW) Complaint of having to take specific positions to be able to micturate spontaneously or to improve bladder emptying, for example, leaning forwards or backwards on the toilet seat or voiding in the semi-standing position.
  • Dysuria: Complaint of burning or other discomfort during micturition. Discomfort may be intrinsic to the lower urinary tract or external (vulvar dysuria).
  • (Urinary) retention: (NEW) Complaint of the inability to pass urine despite persistent effort.

Q

UTI urinary tract infection def & symptoms

A

Bacteria purifier
BUFD UP

  • finding of microbiological evidence of significant bacteriuria and pyuriaxii usually accompanied by
  • symptoms such as increased bladder sensation, urgency, frequency, dysuria, urgency urinary incontinence, and/or pain in the lower urinary tract.

Q

Recurrent urinary tract infections UTI

A

At least three symptomatic and medically diagnosed UTI in the previous 12 months.

17
Q

UTI examination

A

IF U POo

  • Internal examination
  • Other general examination findings
  • Pad tests
  • Frequency volume chart
  • Urodynamic investigations and pelvic imaging
18
Q

UTI tests

A

MUURC

  • Uroflowmetryl
  • Cystometry
  • Ultrasound
  • Radiological imaging
  • Magnetic resonance imaging
19
Q

SUI types & pathophysiology

A
  • Urethral hypermobility: loss of ligamentous support of urethra to be pressed against
  • Intrinsic sphincter deficiency (ISD): vascular plexus (under urethral urothelium) sensitive to abnormal hormonal levels
20
Q

UI pathophysiology

A
  • Chronic, progressive disease with or without symptoms
  • Disease, trauma, fatigue, ageing may contribute
  • Disturbed balance between closing and opening, storage & emptying functions
  • Urethral overactivity & insufficiency are shared features of all UI
  • Similar patterns of functional disorder – differences in disease due to difference in degree
  • Impaired pelvic structure & function
  • Urethral smooth muscle relaxation can trigger overactivity
  • Relaxatory mechanism of urethra with faster opening function
  • Unintentional opening with pressure drop
  • More pronounced stress component → larger risk of urgency
  • Faster opening mechanism → greater probability of urgency
21
Q

UI causes

A

CIA AgEnt

  • Congenital anomalies
  • Injuries and disease of nervous system
  • Anomalies of detrusor and innervation
  • Ageing
  • Effect of pregnancy and delivery
    i. Injury to CT
    ii. Vascular damage
    iii. Pelvic nerve/ muscle damage (PR)
    iv. Direct injury to urinary tract
22
Q

surgical management of UI

A
23
Q

overactive bladder OAB def

A

= Functional disorder of LUT
= urgency with or without frequency and/ or UUI
= nocturia often associated

24
Q

OAB - neurogenic pathophysiology

A

Disturbed balance between filling and voiding

25
Q

OAB - myogenic pathophysiology

A

Increased irritability of detrusor muscle e.g. hypersensitivity

26
Q

OAB pathophysiology

A
  • Hypoxia & bladder wall thickening + decreased blood flow during detrusor contractions
  • Primary changes in CNS
  • Non-neurogenic release from urothelium
  • Higher degree of nerve stimulation and/ or lower threshold for outflow of signals → ↑ voiding activity
  • Increased afferent activity from bladder to CNS → increase activation of striated muscle in urethral sphincter and pelvic floor → generates afferent input
    = Inhibition of voiding-promoting nerves
27
Q

OAB PFM pathophysiology

A

role of PFM pelvic floor muscle
Relaxation of striated muscles in urethra → pressure drop → starts micturition = premature micturition reflex

28
Q

normal bladder VS OAB

A

normal: detrusor muscle contracting when bladder is full

OAB: detrusor muscle contracting before bladder is full

29
Q

OAB conservative management

A
  • PFM training
  • NES
  • Bladder training
  • Medication
  • Physiotherapeutic treatment modalities should be based on the underlying pathology causing OAB
30
Q

bladder training management hypotheses

A
  • Improved cortical inhibition over involuntary detrusor contractions
  • Improved cortical facilitation over urethral closure during bladder filling
  • Improved central modulation of afferent sensory impulses
  • Individual become more knowledgeable and aware of circumstances that cause incontinence and so changing behaviour in ways that increase the ‘reverse capacity’ of the lower urinary tract system
31
Q

bladder training management

A
  • Patient education on bladder, incontinence, and urgency control strategies
  • Scheduled voiding regime – 1 hour interval (shorter times may be indicated) during waking hours
  • Increase schedule 15-30 minutes per week
  • Positive reinforcement techniques – use of social media
  • Interdisciplinary approach – address diet
  • Re-assess after 3 weeks
32
Q

PFMT management hypotheses

A
  • Intentional contraction during urgency, and holding of contraction till urge to void disappears
  • Strength training of the PFM with longlasting changes in muscle morphology, which may stabilize neurogenic activity
33
Q

NES management hypotheses

A
  • Change in PFM activity during nervous excitation that automatically inhibit/ prevent detrusor activity
  • Learning process that make patient aware of contracting the PFM during urgency to inhibit involuntary detrusor contraction
  • Increase in strength of PFM that provide more inhibition of overactivity of bladder
