This document provides an overview of overactive bladder (OAB). It defines OAB and its main symptoms of urgency, frequency, and nocturia. It discusses the prevalence of OAB increasing with age and being similar between genders. The document outlines the bladder anatomy and physiology, as well as theories around the etiology and pathophysiology of OAB. It describes the diagnosis and clinical evaluation of OAB through medical history, physical exam, urinalysis, and other tests. Finally, it covers treatment approaches for OAB including behavioral modifications, medications, injections, and surgeries.
Overactive bladder, DR Sharda Jain Lifecare Centre Lifecare Centre
OAB OAB is not synonymous with detrusor overactivity as the former is a symptom based diagnosis whilst the latter is an urodynamic diagnosis.
It has been estimated that 64% of patients with OAB have urodynamically proven detrusor overactivity and that 83% of patient with detrusor overactivity have symptoms suggestive of OAB.

Overactive bladder (OAB) is a common condition that affects millions of people. Overactive bladder isn't a disease. It's the name of a group of urinary symptoms. The most common symptom of OAB is a sudden urge to urinate that you can't control. Some people will leak urine when they feel the urge.
Urinary incontinence is loss of bladder control. Symptoms can range from mild leaking to uncontrollable wetting. It can happen to anyone, but it becomes more common with age.
Most bladder control problems happen when muscles are too weak or too active. If the muscles that keep your bladder closed are weak, you may have accidents when you sneeze, laugh or lift a heavy object. This is stress incontinence. If bladder muscles become too active, you may feel a strong urge to go to the bathroom when you have little urine in your bladder. This is urge incontinence or overactive bladder. There are other causes of incontinence, such as prostate problems and nerve damage.
Presentation, diagnosis and treatment of urinary incontinence (UI). Includes discussion of Stress, Urge, Mixed, Overflow types of UI, Urodynamic testing, Pelvic floor exercise, and Medical vs Surgery treatment options.

Why invest into infodemic management in health emergenciesTina Purnat
A lecture discussing the challenge of health misinformation and information ecosystem in public health, how this impacts demand promotion in health, and how this then relates to responding to misinformation and infodemics in health emergencies. Appended with lots of tools, guidance and resources for people who want to do more reading.
2. OUTLINES
Introduction… Definition and Prevalence.
Bladder Anatomy and Physiology.
Etiology and Pathophysiology OAB.
Diagnosis and evaluation of OAB.
Treatment of OAB.
3. Definition of OAB
The International Continence Society (ICS) defines
OAB as:
• The presence of “urinary urgency, usually accompanied
by frequency and nocturia, with or without urge
incontinence, in the absence of UTI or other pathology.”
• OAB is based on symptoms and it is a clinical syndrome.
• While detrusor overactivity (DO) is a urodynamic
observation, characterized by involuntary detrusor
contractions during the filling phase.
• OAB and DO are different terms.
Abrams et al, 2002
4. Urge Incontinence
• Sudden & involuntary
loss of urine
Frequency
• 8 or more visits to the toilet per 24 hours
Nocturia
• 2 or more visits to toilet during sleeping hours
OAB
OAB Symptoms
Urgency
• Sudden, strong desire
to void that is difficult to
defer.
5. Sudden desire to pass urine that is difficult to deferurgency
Patient considers that he/she voids too often by day
Normal is < 8 times per 24 hours
Frequency
Waking to urinate during sleep hours considered a
clinical problem if frequency is greater than twice a
night
Nocturia
Involuntary leakage accompanied by or immediately
preceded by urgency
Urge urinary
incontinence
(UUI)
OAB with UUIOAB “wet”
OAB without UUIOAB “dry”
Terminology
6. Urgency
• When I want to go,
I have to rush
because I think I
may wet myself.”
7. • Overall OAB prevalence is 11.8% in adults.
• prevalence increase with age.
• Both genders have similar rates of OAB, but
“OAB wet” is more prevalent in women and
“OAB dry” is more prevalent in men.
• OAB wet common in women due to the relative
weakness of the bladder neck and urethral
sphincter mechanism in women, especial after
pregnancy.
Milsom et al, 2001
PREVALENCE
10. Bladder Anatomy and Physiology
• Normal filling requires
Parasympathetic inhibition and sympathetic
stimulation Reduces detrusor tone.
• Normal emptying requires
Sympathetic inhibition and parasympathetic
stimulation increase detrusor tone.
11. PATHOPHYSIOLOGY AND ETIOLOGY
• The etiology of OAB is complex and poorly
understood.
Neurological hypothesis.
The myogenic hypothesis.
12. PATHOPHYSIOLOGY AND ETIOLOGY
Neurological hypothesis
• DO arises from generalized, nerve-mediated
excitation of the detrusor muscle.
• Normaly the bladder control is modulated in an
inhibitory fashion by the cerebral cortex.
• Damage to the brain can induce DO by reducing
suprapontine inhibition.
• Damage to axonal pathways in the spinal cord allows
the expression of primitive spinal bladder reflexes..
De Groat et al, 1997
13. PATHOPHYSIOLOGY AND ETIOLOGY
The myogenic hypothesis
Overactive detrusor contractions result
from a combination of
1. Increased spontaneous excitation
within smooth muscle of the bladder.
2. Enhanced propagation of this activity to
affect an excessive proportion of the
bladder wall.
Brading, 1997
14. Risk factors for OAB
• Bladder inflammation.
• Chronic bladder outlet obstruction
• Central nervous system disorders
• Pregnancy
• Vaginal delivery
• Postmenopausal status
• Older age (risk increase with age)
• Although the most common cause is idiopathic.
Anderson et al ,2009
15. Types of OAB
There are two types of OAB
• Complicated
1. Poor response to OAB medications
2. Extremely sever OAB symptoms
3. Young age
4. Rec UTI
5. Pelvic surgery
6. Pelvic radiation
7. Poorly controlled DM
• Uncomplicated
have non of above characteristics
Gormley et al ,2014
16. Clinical Evaluation
Diagnosis of OAB is symptom based and involves:
Careful history.
physical exam.
Urinalysis.
Frequency volume chart.
Post-micturation residue.
17. Clinical Evaluation
History should cover the following:
1. Presence or absence , severity, and effect on quality of life
for each of the OAB symptoms including urgency, frequency,
incontinence. Other LUTS should also be assessed.
2. Presence or absence of dysuria and hematuria.
3. Nature and volume of fluid intake.
4. Neurologic disease.
18. Clinical Evaluation
History should cover the following:
5. Obstetric and gynecologic history, previous surgery/
radiotherapy, bowel symptoms.
6. Other medical issues (e.g., closed-angle glaucoma and
cognitive impairment can limit treatment options).
7.Drug history
There are many medications that can exacerbate the
symptoms of OAB (diuretics, alpha agonist)
Abrams et al, 2009
19. Clinical Evaluation
Physical examination
• Abdominal and vaginal examinations should be performed
and, if indicated a rectal examination should also be
undertaken.
• The presence of pelvic organ prolapse, e.g a cystocele,
may cause urinary urgency and frequency as it drags on
the trigone and causes sensation of bladder fullness.
20. Clinical Evaluation
Physical examination
• Bimanual examination will rule out pelvic masses, e.g
ovarian cysts and uterine enlargement, which can also
cause urinary symptoms.
• For women with an atrophic vagina and symptoms of
OAB, estrogen deficiency may be a contributing factor to
their symptoms.
Abrams et al, 2009
21. Clinical Evaluation
Other possible causes of urgency and frequency of
micturition
• Urological;- Urinary tract infection, Bladder tumour,
Bladder stone ,Urethral diverticulum, Small capacity
bladder, Interstitial cystitis, Radiation cystitis.
• Gynecological;-Cystocele, Previous pelvic surgery, Pelvic
mass (fibroids).
• Medical;- Upper motor neuron lesion (Cerebro-vascular
stroke , parkinson’s), Impaired renal function, Congestive
heart failure, Diabetes mellitus, Diabetes insipidus.
22. Clinical Evaluation
Urinalysis
• It should be done to exclude an underlying urinary tract
infection.
Post-micturition residual
• This can be performed to rule out overflow incontinence or
incomplete bladder emptying, which can cause symptoms
of OAB.
24. Clinical Evaluation
Frequency volume chart
• Bladder diaries are useful tool when assessing patients
with urinary symptoms and facilitates history taking.
• Bladder diary done for a minimum of 3 days and the
patient continue his normal eating/drinking patterns as
well as daily activities.
• A record of how much fluid intake , how much urine
output , and how often patient empty his bladder on a
daily basis as well as any leakage occurs and number
and degree of wetness of pads.
26. Clinical Evaluation
Urodynamic evaluation
• It is common practice to prescribe conservative
management and oral pharmacotherapy ttt without a
urodynamic diagnosis.
• Before urodynamic tests are requested, the reasons for
“failure” of drug therapy should be explored:
1. Insufficient duration or poor patient compliance.
2. Insufficient dose, Presence of dry mouth symptoms
is a useful for deciding whether dose is adequate.
3. Idiosyncrasy of response; some people appear to find
better efficacy with certain agents.
4. Side effects.
27. Clinical Evaluation
Urodynamic indicated when
1) Conservative and drug therapy fail adequately to
manage OAB.
2) Complicated cases of OAB.
3) Before invasive surgery.
Abrams et al, 2006
28. Urodynamic Evaluation
Whether to discontinue anti-muscarinic drugs before
the test can be argued either way;
1. Stopping the drugs (48 hr.) gives the best chance of
observing DO if present.
2. while continuing them allows evaluation of the
mechanism underlying residual refractory symptoms.
• The two main urodynamic finding associated with OAB are
DO and increased filling sensation.
• Failure to demonstrate DO on UDS does not rule out its
existence. It is well known that up to 50% of women with
urgency incontinence do not demonstrate DO on UDS.
Hashim et al, 2006
29. Urodynamic Evaluation
• Detrusor overactivity is involuntary detrusor contractions,
There is a rise in Pves with no associated rise in Pabd, and
therefore the subtracted Pdet looks identical to the Pves.

32. Treatment
Non invasive Treatment
• Behavioral therapy
• Oral Medication ( anticholinergic or beta 3 agonist).
• Combined therapy: behavioral and pharmacologic therapy.
• Estrogen for postmenopausal women.
• Role of alpha blocker.
Minimally invasive Treatments:
• Botulinum A-toxin.
• Neuromodulation (post tibial nerve , sacral nerve stimulation)
• Interruption of innervation (central subarachnoid block or sacral
rhizotomy, Peripheral motor and/or sensory block)
Highly invasive Treatments:
• Augmentation cystoplasty.
• Urinary diversion.
33. Barriers to Treatment
1. Part of normal aging or everyday life.
2. Not severe or frequent enough to treat.
3. Too Shameful to discuss.
4. Treatment won't help.
34. Behavioral Modifications
Dietary Changes and fluid Management
Timed voiding
Bladder training
Pelvic floor therapy
• Pelvic floor training ( Kegel exercises).
• Biofeedback ( auditory or visual feedback).
• Vaginal weights
• Pelvic floor electrical or magnetic stimulation.
Labrie et al, 2013
35. Behavioral Modifications
1.Dietary Changes and fluid Management
• Weight loss in obese patient.
• Cessation of smoking.
• Avoid bladder irritant (Caffeine, Alcohol, spicy food,
acidic food).
• Avoid Diuretics and excessive fluid intake especial
before bed time.
• TTT constipation.
• In patient with lower extremity edema elevation of leg
before bed time help to prevent nocturia.
Ayeleke,et al ,2013
36. Cont… Behavioral Modifications
• 10 foods and drinks should avoided in overactive
bladder (bladder irritants).

39. Cont…Behavioral Modifications
2.Timed (scheduled) voiding
• Voiding by routine schedule with constant
interval between void(every 2 -3 hours).
• This help to empty the bladder before
incontinence occurs and decrease urgency and
frequency.
• Voiding interval may be changed throughout the
day to match patients’ incontinence pattern.
Ostaszkiewicz , et al , 2004
40. Cont.. Behavioral Modifications
3.Bladder training
It involves two processes
1. Modification of voiding interval by
Gradual increase of voiding interval by 15- 60 min
every 1-2 week until an acceptable voiding interval
is achieved without incontinence.
(initial interval determined by pre-ttt voiding diary).
41. Cont.. Behavioral Modifications
CONT… Bladder training
2. Urge control (bladder inhibition)
Suppressing the urge using any of following methods;
• keeping the body calm until urge subsides.
• taking slow deep breath.
• concentration on elimination the urge by mental
calculation or mental imaging.
• Contraction of pelvic floor muscle.
After the urge subside don't urinate until the next
scheduled void.
Bladder training required a motivated patient with
sufficient cognitive function.
Wallace SA ,et al , 2004
42. Cont…. Behavioral Modifications
4. Pelvic floor Training (kegel exercises)
• It consists of Intermittent voluntary maximal
contraction of pelvic floor muscles
• Each contraction is held 6-8 seconds and
followed by brief period of relaxation.
• A common regimen is set of 10 contraction 3
times per day.
• Continence improved 6 -12 weeks after PFME.
Neumamm PB , et al , 2006
43. Cont…. Behavioral Modifications
Contraction of pelvic floor muscle is the
best done when lying down.
But it can be done during different activity
as sitting in a meeting or stopping in your
car in a traffic light or when talking in
telephone.
44. Cont…. Behavioral Modifications
Lie on the back and put
your legs apart from each
other and contract PFM for
5 sec
Lie on the back with flexion
of the knees then lift up your
hip slowly for 5 sec.
Lie down with extension of
the legs then stretch the toes
upwards for 5 sec.
Sit cross legged and
contract pelvic
muscle slowly for 5
sec
Stand with
elbows close
together then
left up the
heels for 5 sec
Put the hands on
floor then elevate
your back every 5
sec
46. Cont…. Behavioral Modifications
5.Pelvic floor Training with
Biofeedback
• Biofeedback by auditory or visual
methods is very helpful to gain
better voluntary control over
pelvic floor muscle than verbal
instruction alone.
• A sensors are applied to vagina or
rectum and measure degree of
pelvic floor muscle contraction.
Weatherall , et al ,2002
