Urinary incontinence: the management of
urinary incontinence in women
Contents
NICE clinical guideline 40
Urinary incontinence (UI) is a common condition that may affect women of all
ages, with a wide range of severity and nature. Although rarely life-
threatening, UI may seriously influence the physical, psychological and social
wellbeing of affected individuals. The impact on the families and carers of
women with UI may be profound, and the resource implications for the health
service considerable.
UI is defined by the International Continence Society as ‘the complaint of any
involuntary leakage of urine'. UI may occur as a result of a number of
abnormalities of function of the lower urinary tract or as a result of other
illnesses, which tend to cause leakage in different situations.
• Stress UI is involuntary urine leakage on effort or exertion or on sneezing
• Urge UI is involuntary urine leakage accompanied or immediately preceded
by urgency (a sudden compelling desire to urinate that is difficult to defer).
• Mixed UI is involuntary urine leakage associated with both urgency and
exertion, effort, sneezing or coughing.
Overactive bladder syndrome (OAB) is defined as urgency that occurs with or
without urge UI and usually with frequency and nocturia. OAB that occurs with
urge UI is known as ‘OAB wet'. OAB that occurs without urge UI is known as
‘OAB dry'. These combinations of symptoms are suggestive of the
urodynamic finding of detrusor overactivity, but can be the result of other
forms of urethrovesical dysfunction.
This guideline focuses on the management of stress UI, OAB and urge UI,
and mixed UI in women. It does not address transient or continuous UI or UI
that is provoked by specific stimuli such as sexual intercourse, or laughing or
giggling. Leakage in these situations may, however, be a manifestation of
abnormalities of lower urinary tract function, such as detrusor overactivity or
urodynamic stress incontinence, that are covered by the guideline.
NICE clinical guideline 40
Woman-centred care
This guideline offers best-practice advice on the care of women with UI.
Treatment and care should take into account women's individual needs and
preferences. Women with UI should have the opportunity to make informed
decisions about their care and treatment. If women do not have the capacity
to make decisions, healthcare professionals should follow the Department of
Health guidelines ‘Reference guide to consent for examination or treatment'
(2001) (available from www.dh.gov.uk). From April 2007 healthcare
professionals will need to follow a code of practice accompanying the Mental
Good communication between healthcare professionals and women is
essential. It should be supported by the provision of evidence-based
information offered in a form that is tailored to the needs of the individual
woman. Treatment, care and the information women are given about it should
be culturally appropriate. It should also be accessible to women who have
additional needs, such as physical, sensory or learning disabilities, and to
women who do not speak or read English.
Carers and relatives should also be provided with the information and support
NICE clinical guideline 40
Key priorities for implementation
Italic text following a recommendation gives a short summary of the evidence
supporting that recommendation, more detail is available in the full guideline
(see section 5).
Assessment and investigation
• At the initial clinical assessment, the woman's urinary incontinence (UI)
should be categorised as stress UI, mixed UI, or urge UI/overactive bladder
syndrome (OAB). Initial treatment should be started on this basis. In mixed
UI, treatment should be directed towards the predominant symptom.
Expert opinion concludes that symptomatic categorisation of UI based on reports
from the woman and history taking is sufficiently reliable to inform initial, non-
invasive treatment decisions. (See section 3.2 of the full guideline.)
• Bladder diaries should be used in the initial assessment of women with UI
or OAB. Women should be encouraged to complete a minimum of 3 days
of the diary covering variations in their usual activities, such as both
working and leisure days.
Bladder diaries are a reliable method of quantifying urinary frequency and
incontinence episodes. The Guideline Development Group (GDG) concluded that
a 3-day period allows variation in day-to-day activities to be captured while
securing reasonable compliance. (See section 3.9 of the full guideline.)
• The use of multi-channel cystometry, ambulatory urodynamics or
videourodynamics is not recommended before starting conservative
• For the small group of women with a clearly defined clinical diagnosis of
pure stress UI, the of multi-channel cystometry is not routinely
• Multi-channel filling and voiding cystometry is recommended in women
before surgery for UI if:
– there is clinical suspicion of detrusor overactivity, or
NICE clinical guideline 40
– there has been previous surgery for stress incontinence or anterior
compartment prolapse, or
– there are symptoms suggestive of voiding dysfunction.
Ambulatory urodynamics or videourodynamics may also be considered in
these circumstances.
It has not been shown that carrying out urodynamic investigations before initial
treatment improves outcome. Complex reconstructive urological procedures were
developed for use in specific urodynamic abnormalities. Hence, the GDG
concluded that urodynamic investigations should be used to demonstrate the
presence of specific abnormalities before undertaking these procedures. The
GDG considered that urodynamic investigations are also of value if the clinical
diagnosis is unclear prior to surgery or if initial surgical treatment has failed. (See
section 3.11 of the full guideline.)
Conservative management
• A trial of supervised pelvic floor muscle training of at least 3 months'
duration should be offered as first-line treatment to women with stress or
There is good evidence that daily pelvic floor muscle training continued for
3 months is a safe and effective treatment for stress and mixed UI. (See
section 4.2 of the full guideline.)
• Bladder training lasting for a minimum of 6 weeks should be offered as first-
line treatment to women with urge or mixed UI.
There is good evidence that bladder training is an effective treatment for urge or
mixed UI, with fewer adverse effects and lower relapse rates than treatment with
antimuscarinic drugs. (See section 4.3 of the full guideline.)
• Immediate release non-proprietary oxybutynin should be offered to women
with OAB or mixed UI as first-line drug treatment if bladder training has
been ineffective. If immediate release oxybutynin is not well tolerated,
darifenacin, solifenacin, tolterodine, trospium, or an extended release or
transdermal formulation of oxybutynin should be considered as
NICE clinical guideline 40
alternatives. Women should be counselled about the adverse effects of
antimuscarinic drugs.
There is no evidence of a clinically important difference in efficacy between
antimuscarinic drugs. However, immediate release non-proprietary oxybutynin is
the most cost effective of the available options. (See section 4.4.1 of the full
guideline.)
• Pelvic floor muscle training should be offered to women in their first
pregnancy as a preventive strategy for UI.
There is evidence that pelvic floor muscle training used during a first pregnancy
reduces the likelihood of postnatal UI. (See section 4.7 of the full guideline.)
Surgical management
• Sacral nerve stimulation is recommended for the treatment of UI due to
detrusor overactivity in women who have not responded to conservative
treatments. Women should be offered sacral nerve stimulation on the basis
of their response to preliminary percutaneous nerve evaluation. Life-long
follow-up is recommended.
The treatment options for women who have detrusor overactivity and have not
responded to conservative therapy are all costly and associated with significant
morbidity. There is a stronger body of evidence for the effectiveness of sacral
nerve stimulation than for other procedures. Up to two-thirds of patients achieve
continence or substantial improvement in symptoms after this treatment. (See
section 5.1 of the full guideline.)
• Retropubic mid-urethral tape procedures using a ‘bottom-up' approach with
macroporous (type 1) polypropylene meshes are recommended as
treatment options for stress UI where conservative management has failed.
Open colposuspension and autologous rectus fascial sling are the
recommended alternatives when clinically appropriate.
Many procedures have been described for the treatment of stress UI; although
there is no strong evidence of superior effectiveness of any one, the best available
data support the use of retropubic mid-urethral tape procedures, colposuspension
NICE clinical guideline 40
and autologous rectus fascial sling. Retropubic mid-urethral tape procedures
consume fewer hospital resources and are associated with faster recovery than
the other two procedures. (See section 5.2 of the full guideline.)
Competence of surgeons performing operative procedures for UI in
• Surgery for UI should be undertaken only by surgeons who have received
appropriate training in the management of UI and associated disorders or
who work within a multidisciplinary team with this training, and who
regularly carry out surgery for UI in women.
The expertise of the surgeon is one of the factors that influence surgical
outcomes. The best outcomes are achieved when surgeons and/or their
multidisciplinary team have specialist training and regular practice in
continence surgery. (See section 6 of the full guideline.)
NICE clinical guideline 40
The following guidance is based on the best available evidence. The full
guidance (see section 5 for details).
1 Guidance
1.1 Assessment and investigation
1.1.1 History-taking and physical examination
At the initial clinical assessment, the woman's UI should be
categorised as stress UI, mixed UI, or urge UI/OAB. Initial
treatment should be started on this basis. In mixed UI, treatment
should be directed towards the predominant symptom.
The clinical assessment should seek to identify relevant
predisposing and precipitating factors and other diagnoses that
may require referral for additional investigation and treatment.
1.1.2 Assessment of pelvic floor muscles
Routine digital assessment of pelvic floor muscle contraction
should be undertaken before the use of supervised pelvic floor
muscle training for the treatment of UI.
1.1.3 Assessment of prolapse
Women with UI who have symptomatic prolapse that is visible at or
below the vaginal introitus should be referred to a specialist.
1.1.4 Urine testing
A urine dipstick test should be undertaken in all women presenting
with UI to detect the presence of blood, glucose, protein,
leucocytes and nitrites in the urine.
Women with symptoms of urinary tract infection (UTI) whose urine
tests positive for both leucocytes and nitrites should have a
NICE clinical guideline 40
midstream urine specimen sent for culture and analysis of antibiotic
sensitivities. An appropriate course of antibiotic treatment should
be prescribed pending culture results.
Women with symptoms of UTI whose urine tests negative for either
leucocytes or nitrites should have a midstream urine specimen sent
for culture and analysis of antibiotic sensitivities. The healthcare
professional should consider the prescription of antibiotics pending
culture results.
Women who do not have symptoms of UTI, but whose urine tests
positive for both leucocytes and nitrites, should not be offered
antibiotics without the results of midstream urine culture.
Women who do not have symptoms of UTI and whose urine tests
negative for either leucocytes or nitrites are unlikely to have UTI
and should not have a urine sample sent for culture.
1.1.5 Assessment of residual urine
The measurement of post-void residual volume by bladder scan or
catheterisation should be performed in women with symptoms
suggestive of voiding dysfunction or recurrent UTI. A bladder scan
should be used in preference to catheterisation on the grounds of
acceptability and lower incidence of adverse events.
Women who are found to have a palpable bladder on bimanual or
abdominal examination after voiding should be referred to a
NICE clinical guideline 40
1.1.6 Referral
Women with UI who have any of the following should receive an
urgent referral:
• microscopic haematuria if aged 50 years and older • visible haematuria • recurrent or persisting UTI associated with haematuria if aged
40 years and older
• suspected malignant mass arising from the urinary tract.
In women with UI, further indications for consideration for referral to
a specialist service include:
• persisting bladder or urethral pain • clinically benign pelvic masses • associated faecal incontinence • suspected neurological disease • symptoms of voiding difficulty • suspected urogenital fistulae • previous continence surgery • previous pelvic cancer surgery • previous pelvic radiation therapy.
1.1.7 Symptom scoring and quality-of-life assessment
The following incontinence-specific quality-of-life scales are
recommended when therapies are being evaluated: ICIQ, BFLUTS,
I-QOL, SUIQQ, UISS, SEAPI-QMM, ISI, and KHQ.
1.1.8 Bladder diaries
should be used in the initial assessment of women
with UI or OAB. Women should be encouraged to complete a
1 NICE's ‘Referral guidelines for suspected cae urgent referral as
the patient being seen within the national target for urgent referrals (currently 2 weeks).
2 See full guidance for details.
NICE clinical guideline 40
minimum of 3 days of the diary covering variations in their usual
activities, such as both working and leisure days.
1.1.9 Pad testing
Pad tests are not recommended in the routine assessment of
1.1.10 Urodynamic
1.1.10.1 The use of multi-channel cystometry, ambulatory urodynamics or
videourodynamics is not recommended before starting
conservative treatment.
1.1.10.2 For the small group of women with a clearly defined clinical
diagnosis of pure stress UI, the use of multi-channel cystometry is
not routinely recommended.
1.1.10.3 Multi-channel
filling and voiding cystometry is recommended in
women before surgery for UI if:
• there is clinical suspicion of detrusor overactivity, or • there has been previous surgery for stress incontinence or
anterior compartment prolapse, or
• there are symptoms suggestive of voiding dysfunction.
Ambulatory urodynamics or videourodynamics may also be
considered in these circumstances.
Other tests of urethral competence
1.1.11.1 The Q-tip, Bonney, Marshall, and Fluid-Bridge tests are not
recommended in the assessment of women with UI.
1.1.12 Cystoscopy
1.1.12.1 Cystoscopy is not recommended in the initial assessment of
women with UI alone.
NICE clinical guideline 40
1.1.13 Imaging
1.1.13.1 Imaging (magnetic resonance imaging, computed tomography,
X-ray) is not recommended for the routine assessment of women
with UI. Ultrasound is not recommended other than for the
assessment of residual urine volume.
1.2 Conservative management
1.2.1 Lifestyle interventions
A trial of caffeine reduction is recommended for the treatment of
1.2.1.2 Consider
modification of high or low fluid intake in women
Women with UI or OAB who have a body mass index greater than
30 should be advised to lose weight.
1.2.2 Physical therapies
A trial of supervised pelvic floor muscle training of at least
3 months' duration should be offered as first-line treatment to
women with stress or mixed UI.
Pelvic floor muscle training programmes should comprise at least
eight contractions performed three times per day.
If pelvic floor muscle training is beneficial, an exercise programme
should be continued.
Perineometry or pelvic floor electromyography as biofeedback
should not be used as a routine part of pelvic floor muscle training.
Electrical stimulation should not routinely be used in the treatment
of women with OAB.
NICE clinical guideline 40
Electrical stimulation should not routinely be used in combination
with pelvic floor muscle training.
1.2.2.7 Electrical
stimulation and/or biofeedback should be considered in
women who cannot actively contract pelvic floor muscles in order to
aid motivation and adherence to therapy.
1.2.3 Behavioural therapies
Bladder training lasting for a minimum of 6 weeks should be offered
as first-line treatment to women with urge or mixed UI.
If women do not achieve satisfactory benefit from bladder training
programmes, the combination of an antimuscarinic agent with
bladder training should be considered if frequency is a troublesome
In women with UI who also have cognitive impairment, prompted
and timed voiding toileting programmes are recommended as
strategies for reducing leakage episodes.
1.2.4 Drug therapies
1.2.4.1 Immediate
non-proprietary oxybutynin should be offered to
women with OAB or mixed UI as first-line drug treatment if bladder
training has been ineffective. If immediate release oxybutynin is not
well tolerated, darifenacin, solifenacin, tolterodine, trospium, or an
extended release or transdermal formulation of oxybutynin should
be considered as alternatives. Women should be counselled about
the adverse effects of antimuscarinic drugs.
An early treatment review should be undertaken following any
change in antimuscarinic drug therapy.
Propiverine should be considered as an option to treat frequency of
urination in women with OAB, but is not recommended for the
treatment of UI.
NICE clinical guideline 40
1.2.4.4 Flavoxate,
propantheline and imipramine should not be used for the
treatment of UI or OAB in women.
The use of desmopressin may be considered specifically to reduce
nocturia in women with UI or OAB who find it a troublesome
symptom. However, the use of desmopressin for nocturia in women
with idiopathic UI is outside the UK marketing authorisation for the
product. Informed consent to treatment should be obtained and
1.2.4.6 Duloxetine
not recommended as a first-line treatment for women
with predominant stress UI. Duloxetine should not routinely be used
as a second-line treatment for women with stress UI, although it
may be offered as second-line therapy if women prefer
pharmacological to surgical treatment or are not suitable for
surgical treatment. If duloxetine is prescribed, women should be
counselled about its adverse effects.
Systemic hormone replacement therapy is not recommended for
the treatment of UI.
Intravaginal oestrogens are recommended for the treatment of OAB
symptoms in postmenopausal women with vaginal atrophy.
1.2.5 Non-therapeutic interventions
Absorbent products, hand held urinals and toileting aids should not
be considered as a treatment for UI. They should be used only as:
• a coping strategy pending definitive treatment • an adjunct to ongoing therapy • long-term management of UI only after treatment options have
catheterisation (intermittent or indwelling urethral or
suprapubic) should be considered for women in whom persistent
urinary retention is causing incontinence, symptomatic infections,
NICE clinical guideline 40
or renal dysfunction, and in whom this cannot otherwise be
corrected. Healthcare professionals should be aware, and explain
to women, that the use of indwelling catheters in urge UI may not
result in continence.
1.2.5.3 Intermittent
urethral catheterisation should be used for women with
urinary retention who can be taught to self-catheterise or who have
a carer who can perform the technique.
Careful consideration should be given to the impact of long-term
indwelling urethral catheterisation. The practicalities, benefits and
risks should be discussed with the patient or, if appropriate, her
carer. Indications for the use of long-term indwelling urethral
catheters for women with UI include:
• chronic urinary retention in women who are unable to manage
intermittent self-catheterisation
• skin wounds, pressure ulcers or irritations that are being
contaminated by urine
• distress or disruption caused by bed and clothing changes • where a woman expresses a preference for this form of
1.2.5.5 Indwelling
catheters should be considered as an
alternative to long-term urethral catheters. Healthcare professionals
should be aware, and explain to women, that they may be
associated with lower rates of symptomatic UTI, ‘by-passing' and
urethral complications than indwelling urethral catheters.
Intravaginal and intraurethral devices are not recommended for the
routine management of UI in women. Women should not be
advised to consider such devices other than for occasional use
when necessary to prevent leakage, for example during physical
NICE clinical guideline 40
1.2.6 Complementary therapies
1.2.6.1 Complementary
therapies are not recommended for the treatment
1.2.7 Preventive use of conservative therapies
Pelvic floor muscle training should be offered to women in their first
pregnancy as a preventive strategy for UI.
1.3 Surgical management
1.3.1 Discussion of benefits and risks
Any woman wishing to consider surgical treatment for UI should be
informed about the benefits and risks of surgical and non-surgical
options. Counselling should include consideration of the woman's
child-bearing wishes.
1.3.2 Procedures for OAB
Sacral nerve stimulation is recommended for the treatment of UI
due to detrusor overactivity in women who have not responded to
conservative treatments. Women should be offered sacral nerve
stimulation on the basis of their response to preliminary
percutaneous nerve evaluation. Life-long follow-up is
1.3.2.2 Augmentation
for the management of idiopathic
detrusor overactivity should be restricted to women who have not
responded to conservative treatments and who are willing and able
to self-catheterise. Preoperative counselling should include
common and serious complications: bowel disturbance, metabolic
acidosis, mucus production and/or retention in the bladder, UTI and
urinary retention. The small risk of malignancy occurring in the
augmented bladder should also be discussed. Life-long follow-up is
NICE clinical guideline 40
Urinary diversion should be considered for a woman with OAB only
when conservative treatments have failed, and if sacral nerve
stimulation and augmentation cystoplasty are not appropriate or are
unacceptable to her. Life-long follow-up is recommended.
Bladder wall injection with botulinum toxin A should be used in the
treatment of idiopathic detrusor overactivity only in women who
have not responded to conservative treatments, and who are willing
and able to self-catheterise. Women should be informed about the
lack of long-term data. There should be special arrangements for
audit or research. The use of botulinum toxin A for this indication is
outside the UK marketing authorisation for the product. Informed
consent to treatment should be obtained and documented.
Botulinum toxin B is not recommended for the treatment of women
with idiopathic OAB.
1.3.3 Procedures for stress UI
1.3.3.1 Retropubic
tape procedures using a ‘bottom-up'
approach with macroporous (type 1) polypropylene meshes are
recommended as treatment options for stress UI if conservative
management has failed. Open colposuspension and autologous
rectus fascial sling are the recommended alternatives when
clinically appropriate.
Synthetic slings using a retropubic ‘top-down' or a transobturator
foramen approach are recommended as alternative treatment
options for stress UI if conservative management has failed,
provided that women are made aware of the lack of long-term
Synthetic slings using materials other than polypropylene that are
not of a macroporous (type 1) construction are not recommended
for the treatment of stress UI.
NICE clinical guideline 40
1.3.3.4 Intramural
bulking agents (glutaraldehyde cross-linked collagen,
silicone, carbon-coated zirconium beads, or hyaluronic acid/dextran
co-polymer) should be considered for the management of stress UI
if conservative management has failed. Women should be made
• repeat injections may be required to achieve efficacy • efficacy diminishes with time • efficacy is inferior to that of retropubic suspension or sling.
In view of the associated morbidity, the use of an artificial urinary
sphincter should be considered for the management of stress UI in
women only if previous surgery has failed. Life-long follow-up is
1.3.3.6 Laparoscopic
is not recommended as a routine
procedure for the treatment of stress UI in women. The procedure
should be performed only by an experienced laparoscopic surgeon
working in a multidisciplinary team with expertise in the assessment
and treatment of UI.
Anterior colporrhaphy, needle suspensions, paravaginal defect
repair and the Marshall–Marchetti–Krantz procedure are not
recommended for the treatment of stress UI.
Autologous fat and polytetrafluoroethylene used as intramural
bulking agents are not recommended for the treatment of stress UI.
1.4 Competence of surgeons performing operative
procedures for UI in women
Surgery for UI should be undertaken only by surgeons who have
received appropriate training in the management of UI and
associated disorders, or who work within a multidisciplinary team
with this training, and who regularly carry out surgery for UI in
NICE clinical guideline 40
Training should be sufficient to develop the knowledge and generic
skills documented below.
Knowledge should include the:
• specific indications for surgery • required preparation for surgery, including preoperative
• outcomes and complications of the proposed procedure • anatomy relevant to the procedure • steps involved in the procedure • alternative management options • likely postoperative progress.
Generic skills should include:
• the ability to explain procedures and possible outcomes to
patients and family and to obtain informed consent
• the necessary hand–eye dexterity to complete the procedure
safely and efficiently, with appropriate use of assistance
• the ability to communicate with and manage the operative team
• the ability to prioritise interventions • the ability to recognise when to ask for advice from others • a commitment to multidisciplinary team working.
Training should include competence in cystourethroscopy.
Operative competence of surgeons undertaking surgical procedures
to treat UI or OAB in women should be formally assessed by
trainers through a structured process.
Surgeons who are already carrying out procedures for UI should be
able to demonstrate that their training, experience and current
practice equates to the standards laid out for newly trained
NICE clinical guideline 40
Surgery for UI or OAB in women should be undertaken only by
surgeons who carry out a sufficient case load to maintain their
skills. An annual workload of at least 20 cases of each primary
procedure for stress UI is recommended. Surgeons undertaking
fewer than five cases of any procedure annually should do so only
with the support of their clinical governance committee; otherwise
referral pathways should be in place within clinical networks.
There should be a nominated clinical lead within each surgical unit
with responsibility for continence and prolapse surgery. The clinical
lead should work within the context of an integrated continence
A national audit of continence surgery should be undertaken.
surgery should maintain careful
audit data and submit their outcomes to national registries such as
those held by the British Society of Urogynaecology (BSUG) and
British Association of Urological Surgeons Section of Female and
Reconstructive Urology (BAUS-SFRU).
2 Notes on the scope of the guidance
All NICE guidelines are developed in accordance with a scope that defines
what the guideline will and will not cover. The scope of this guideline is
This clinical guideline concerns the management of UI in adult women. It
• stress UI • OAB (with or without urge UI) • mixed UI.
NICE clinical guideline 40
It has been developed with the aim of providing guidance on:
• initial and ongoing assessments and investigations • appropriate use of conservative and surgical treatment options • the competence required by surgeons performing the primary and
subsequent operative procedures.
Areas outside the remit of the guideline include:
• the management and treatment of comorbidities, such as pelvic organ
prolapse, except where they relate to the treatment of UI and/or OAB
• incontinence caused by neurological disease • incontinence in men • incontinence in children • anal incontinence.
How this guideline was developed
NICE commissioned the National Collaborating Centre for Women's and
Children's Health to develop this guideline. The Centre established a
Guideline Development Group (see appendix A), which reviewed the evidence
and developed the recommendations. An independent Guideline Review
Panel oversaw the development of the guideline (see appendix B).
There is more information in the booklet: ‘The guideline development process:
an overview for stakeholders, the public and the NHS', which is available from
www.nice.org.uk/guidelinesprocess or by telephoning 0870 1555 455 (quote
reference N1113).
3 Implementation
The Healthcare Commission assesses the performance of NHS organisations
in meeting core and developmental standards set by the Department of Health
in ‘Standards for better health' issued in July 2004. Implementation of clinical
guidelines forms part of the developmental standard D2. Core standard C5
NICE clinical guideline 40
says that national agreed guidance should be taken into account when NHS
organisations are planning and delivering care.
NICE has developed tools to help organisations implement this guidance
(listed below). These are available on our website (www.nice.org.uk/CG040).
• Slides highlighting key messages for local discussion. • Costing tools, including:
– costing report to estimate the national savings and costs associated with
– costing template to estimate the local costs and savings involved.
• Implementation advice on how to put the guidance into practice and
national initiatives that support this locally.
• Audit criteria to monitor local practice.
4 Research
The Guideline Development Group has made the following recommendations
for research, based on its review of evidence, to improve NICE guidance and
patient care in the future. The Guideline Development Group's full set of
research recommendations is detailed in the full guideline (see section 5).
4.1 Multi-channel cystometry
Does carrying out multi-channel cystometry affect the outcome and cost-
effectiveness of interventions for UI or OAB?
Why this is important
It has long been held that clinical assessment of patients with UI is unreliable;
however, the widespread availability of invasive urodynamic testing, by
multi-channel cystometry in particular, has led to an assumption of improved
diagnostic value. Although many currently available treatments for UI and
OAB have been evaluated in patients with known urodynamic background, it
has never been shown for any treatment that carrying out urodynamic
investigation improves outcome. Urodynamic investigation has its own
associated cost and morbidity. Many units have significant waiting times for
NICE clinical guideline 40
investigation, and hence unnecessary use of investigations has significant
resource implications.
4.2 Mid-urethral tape procedures compared with pelvic floor
muscle training
What is the clinical and cost-effectiveness of mid-urethral tape procedures
compared with pelvic floor muscle training in the first-line treatment of stress
Why this is important
Although there are no useful comparative data on the effectiveness of pelvic
floor muscle training and surgery in the treatment of stress UI, indirect
comparison suggests that surgery is associated with higher cure rates but
also substantially greater morbidity. Hence pelvic floor muscle training is used
as first-line treatment. Information on long-term outcomes from pelvic floor
muscle training is limited, although it appears that a significant number of
women initially treated successfully by pelvic floor muscle training will
ultimately undergo surgery. The development of newer minimal access
procedures with shorter recovery periods than conventional surgery may
make surgery a more acceptable option than previously. The clinical and cost-
effectiveness of these procedures compared with pelvic floor muscle training
has not yet been proven.
4.3 Pelvic floor muscle training
What is the optimum pelvic floor muscle training regimen for women with
Why this is important
There is a large body of evidence to support the use of pelvic floor muscle
training in the treatment of stress and mixed UI. A range of regimens has
been employed, with variation in the number and frequency of exercises
advocated, the duration of treatment, the method of delivery and the role of
adjunctive therapies. Clarity as to the optimum regimen may improve the cost-
effectiveness of this treatment.
NICE clinical guideline 40
4.4 Modifying lifestyle factors
What is the effectiveness of modifying lifestyle factors in reducing the
prevalence and severity of UI and OAB?
Why this is important
Several studies have shown associations between various lifestyle factors and
the prevalence or severity of UI and OAB. There is limited information on the
effect of modifying these factors on urinary symptoms. Such interventions are
in general free from adverse effects, and are cost neutral or cost saving. They
therefore justify further evaluation.
4.5 Physical and behavioural therapies and lifestyle
What is the effectiveness of physical and behavioural therapies and lifestyle
modifications in the prevention of UI in women?
Why this is important
The impact of UI on individual women with the condition, their families and
carers and on the NHS as a whole is huge. Prevention of UI would have
advantages from all perspectives. There is limited information on the use of
antenatal pelvic floor muscle training and some lifestyle modifications in the
prevention of UI. There are, however, no data on the long-term outcomes of
these and other conservative interventions used preventively. For example,
although it has been shown that pelvic floor muscle training used in a first
pregnancy may reduce the prevalence of UI postnatally, it is not known
whether this has any influence following subsequent pregnancies.
4.6 Botulinum toxin A
What is the effectiveness of botulinum toxin A in the treatment of idiopathic
detrusor overactivity?
Why this is important
There is a gap in our current management of idiopathic detrusor overactivity,
between available conservative treatments of limited effectiveness and major
NICE clinical guideline 40
surgical options associated with a high level of morbidity. Botulinum toxin A
has recently become available for the treatment of detrusor overactivity, and
has rapidly been adopted in clinical practice to fill this gap. This has, however,
occurred in advance of high-quality data on efficacy, safety and long-term

7 Updating the guideline
NICE clinical guidelines are updated as needed so that recommendations
take into account important new information. We check for new evidence 2
and 4 years after publication, to decide whether all or part of the guideline
should be updated. If important new evidence is published at other times, we
may decide to do a more rapid update of some recommendations.

Women with UI or OAB
Advise women with UI or OAB to: • modify high or low fluid intake • lose weight if their body mass index is over 30.
Initial assessment
Categorise UI as stress UI, urge UI/OAB or mixed UI. Start treatment on this basis.
• Identify factors that may require referral.
• Ask the woman to complete a bladder diary for at least 3 days, covering variations in usual activities (e.g. working and
• Measure post-void residual urine in women with symptoms of voiding dysfunction or recurrent UTI. If available, use a
bladder scan in preference to catheterisation.
• Use urine dipstick tests to detect blood, glucose, protein, leucocytes and nitrites.
Dipstick test results
Positive for leucocytes and nitrites
Negative for either leucocytes or nitrites
Send a mid-stream urine sample for culture and antibiotic sensitivity analysis.

The following are not recommended: • urodynamics before conservative treatment
• ultrasound, except to assess residual urine volume
• routine use of pad tests or imaging (MRI, CT and X-ray)
MRI, magnetic resonance imaging;

Indications for referral
Urgently refer women with any of the following:a
- microscopic haematuria if aged 50 years and
- visible haematuria - recurrent or persisting UTI associated with
haematuria if aged 40 years and older
- suspected pelvic mass arising from the urinary
• Determine treatment according to whether
stress or urge UI is the dominant symptom.
• Refer women with:
• See pages 35 and 36
- symptomatic prolapse visible at or below the
vaginal introitus
- palpable bladder on bimanual or physical
examination after voiding.
• Consider referring women with:
- persisting bladder or urethral pain - clinically benign pelvic masses - associated faecal incontinence - suspected neurological disease - voiding difficulty - suspected urogenital fistulae - previous continence surgery - previous pelvic cancer surgery - previous pelvic radiation therapy.
a NICE's ‘Referral guidelines for suspected cancer' (www.nice.org.uk/CG027) define urgent referral as the patient being seen within the national target for urgent referrals (currently 2 weeks).
NICE clinical guideline 40
Stress UI
Stress UI
• First-line treatment for stress or mixed UI should be pelvic floor muscle training (PFMT) lasting at
least 3 months. - Digitally assess pelvic floor muscle contraction before PFMT. - PFMT should consist of at least eight contractions, three times a day. - If PFMT is beneficial, continue an exercise programme. - During PFMT, do not routinely use:
electrical stimulation; consider it and/or biofeedback in women who cannot actively contract
their pelvic floor muscles
biofeedback using perineometry or pelvic floor electromyography.
- should not be used as a first-line treatment for stress UI - should not routinely be used as a second-line treatment for stress UI - may be offered as an alternative to surgical treatment; counsel women about adverse effects.

circumstances as multi-channel filling and voiding cystometry.
Stress UI
• Discuss the risks and benefits of surgical and non-surgical options. Consider the woman's child-bearing
wishes during the discussion.
• If conservative treatments have failed, consider:
- retropubic mid-urethral tape procedures using a ‘bottom-up' approach with macroporous (type 1)
polypropylene meshes, open colposuspension or autologous rectus fascial sling
- synthetic slings using a retropubic ‘top-down' or a transobturator foramen approach. Explain the lack of
long-term outcome data
- intramural bulking agents (glutaraldehyde crosslinked collagen, silicone, carbon-coated zirconium beads,
hyaluronic acid/dextran co-polymer). Explain that:
repeat injections may be needed the effect decreases over time the technique is less effective than retropubic suspension or sling.
- an artificial urinary sphincter if previous surgery has failed.*
• The following are not recommended for stress UI:
- routine use of laparoscopic colposuspension - synthetic slings using materials other than polypropylene that are not of a macroporous (type 1)
- anterior colporrhaphy, needle suspensions, paravaginal defect repair and the Marshall–Marchetti–Krantz
- autologous fat and polytetrafluoroethylene as intramural bulking agents.
b The use of desmopressin for idiopathic UI is outside its UK marketing authorisation. Informed consent to treatment should be obtained and documented. * Provide life-long follow-up after this procedure.

OABwith or without urge UI
OAB with or without UI
•
Recommend caffeine reduction.
• First-line treatment for urge or mixed UI should be bladder training lasting at least 6 weeks. If frequency remains
troublesome, consider adding an antimuscarinic drug.
• If bladder training is ineffective, prescribe non-proprietary oxybutynin.
- Counsel the woman about adverse effects of antimuscarinic drugs. - If oxybutynin is not tolerated, alternatives are darifenacin, solifenacin, tolterodine, trospium, or different oxybutynin
- Carry out an early treatment review after any change in drug.
• In postmenopausal women with vaginal atrophy, offer intravaginal oestrogens for OAB symptoms.
• In women with UI who also have cognitive impairment, prompted and timed toileting programmes may help reduce
leakage episodes.
• Do not routinely use electrical stimulation in OAB.
Further assessment
Other treatments for UI or OAB
• Do not routinely use muti-channel cystometry
• Consider desmopressin to reduce troublesome
before primary surgery for stress UI
• Use multi-channel filling and voiding cystometry
• Consider propiverine to treat frequency of urination
before surgery for UI if:
- there is clinical suspicion of detrusor overactivity,
• The following are not recommended:
- propiverine for the treatment of UI
- there has been previous surgery for stress UI or
- flavoxate, imipramine and propantheline
anterior compartment prolapse, or
- systemic hormone-replacement therapy
- there are symptoms of voiding dysfunction.
- complementary therapies.
• Ambulatory urodynamics or videourodynamics may
be considered before surgery for UI in the same circumstances as multi-channel filling and voiding cystometry.
OAB with or without UI
• Discuss the risks and benefits of surgical and non-surgical options. Consider the woman's child-bearing wishes
during the discussion.
• If conservative treatments have failed, consider:
botulinum toxin A to treat idiopathic detrusor overactivity in those willing and able to self-catheterise; explain the lack
of long-term data; special arrangements for audit or research should be in place c
- sacral nerve stimulation for UI due to detrusor overactivity; select patients on basis of response to preliminary
peripheral nerve evaluation*
- augmentation cystoplasty in those willing and able to self-catheterise; explain common and serious complications
and the small risk of malignancy in the augmented bladder*
- urinary diversion if sacral nerve stimulation and augmentation cystoplasty are not appropriate or unacceptable.*
b The use of desmopressin for idiopathic UI is outside its UK marketing authorisation. Informed consent to treatment should be obtained and documented.
c The use of botulinum toxin A for this indication is outside its UK marketing authorisation. Informed consent to treatment should be obtained and documented. Do not use botulinum toxin B.

APPLICATION NOTE hERG K+ channel currents and pharmacology using the IonFlux system Introduction HERG (human ether-a go-go-related gene) K+ channels are strongly expressed in the heart and are responsible for a rapid component (IKr) of the repolarizing currents in the cardiac action potential (Curran ‘95; Sanguinetti ‘95). Loss of function mutations affect-ing hERG are associated with some inherited forms of long QT syndrome (LQTS) and increase the risk for a serious ventricular arrhythmia, torsade de pointes (Tanaka ‘97; Moss ‘02). HERG K+ channel inhibition by both cardiac and noncardiac drugs has also been identified as the most common cause of acquired, drug-induced LQTS that may lead to sudden cardiac death (Vandenberg, Walker & Campbell ‘01). In fact, the side effect of hERG K+ channel inhibition is one of the major reasons of drug withdrawal or drug re-labeling in recent years, therefore in vitro evaluation of the effects of drugs on hERG channels expressed heterologously in mammalian cells has been recommended as part of the preclinical safety package by the International Conference on Harmoniza-tion (ICHS7B Expert Working Group, ‘02). The gold standard of evaluating drug effects on hERG K+ current is manual patch-clamp recording. However, this low-throughput, high-cost approach is
