- Ensure that other pathology is not missed

- The severity of symptoms and their impact should be determined rather than just the presence or absence of symptoms. This guides the choice of treatment

- If mixed symptoms are present, treatment should be directed at the predominant problem

13

1 - A urine dipstick test should be done for all women with LUTS

2 - Women who have voiding symptoms should have their PVR checked

3 - A PVR of less than 200 ml is normal

4 - A voiding diary should be used for the initial assessment of all women with UI

5 - Verbally reported voiding frequency has been shown to be as accurate as recorded voiding frequency

6 - Voiding up to 12 times during the day and up to three times at night is normal

7 - Pad testing to objectively quantify urinary leakage is recommended by NICE in the assessment of women with UI

It also identifies problems such as detrusor overactivity and voiding dysfunction which can detrimentally affect the results of continence surgery.

15

Which of the following examinations/investigations would be relevant in the first instance?

1 - Speculum examination

2 - Cervical smear

3 - Vaginal examination

4 - Urinalysis

5 - Blood pressure

1 - True

2 - False: Although many women may be opportunistically offered screening for hypertension and cervical abnormality, they are not indicated for this clinical scenario.

3 - True

4 - True

5 - False: Although many women may be opportunistically offered screening for hypertension and cervical abnormality, they are not indicated for this clinical scenario.

16

What investigations would you recommend to her?

1 - Blood sugar

2 - Midsteam specimen of urine

3 - Intravenous urogram

4 - Pelvic ultrasound (including a postvoid residual)

5 - Bladder diary (frequency–volume chart)

6 - Pelvic CT

1 - False, Blood sugars are not measured routinely unless the urine dipstick shows glycosuria.

2 - True, A midstream specimen of urine will exclude infection

3 - False

4 - True. A pelvic ultrasound is useful to investigate her bulky uterus and exclude a chronic residual of urine and overflow incontinence

5 - True

6 - False. Pelvic CT and intravenous urogram are not indicated as first-line investigations. She does, however, warrant screening for diabetes and a frequency–volume chart to quantify her fluid intake and output.

17

Case study 1
A 63-year-old woman comes to the surgery. She is normally fit and well, but has noticed that over the previous 18 months, she has had problems with a 'weak bladder'. She also notices that she leaked urine in the last three months, which has driven her to seek help.

She has always taken regular exercise and eaten a healthy diet. She has two grown children, both born normally at term, weighing less than 3.7 kg.

She takes no regular medications other than cod liver oil capsules and vitamins. She does not smoke. She lives with her husband, who is a milkman. He leaves for work at 03:45 every day, and wakes her up with the alarm clock.

US: several small fibroids not impinging on bladder, & bladder empties completely.
Culture: no infection urine.
Frequency–volume charting:normal fluid intake of 1500 ml per day, but confirms diurnal frequency of 14 times, with nocturia of three times per night.

Advice:
- avoiding caffeine-containing drinks and alcohol, and
- commence bladder-retraining.

18

Case study 2
A 72-year-old lady , gynaecology outpatient clinic. She complains of urinary frequency, urgency and leaking whilst climbing the stairs. She wears sanitary towels whenever she leaves the house and is extremely embarrassed about her symptoms.

In past, she has had four children by spontaneous vaginal delivery. She lives alone and smokes 20 cigarettes a day.

She provides a urine specimen which shows microscopic haematuria on urinalysis.

Having considered your differential diagnoses, which of the following investigations are initially indicated?

1 - Urodynamics
2 - Urinalysis
3 - Midstream specimen of urine
4 - Urine cytology
5 - Frequency–volume chart
6 - Urgent cystoscopy
7 - Colonoscopy

1 - False: Urodynamics would be indicated only if surgery was being considered.invasive urodynamics tests should not be undertaken until any infection is treated

2 - True
3 - True: MSU mandatory, as UTI could be at least partly responsible for this woman's symptoms

4 - True: urine sample should also be sent for cytology as the possibility of a urinary tract malignancy is raised by the presence of haematuria

5 - True
6 - True: urgent cystoscopy should also be arranged either as an outpatient or a day case providing she is medically fit enough. The possible presence of bladder stones, tumours and inflammatory conditions needs to be determined. Bladder biopsies at the time of cystoscopy may be indicated.

7 - False

Detailed history
1 - severity of the dysfunction, .
2 - Any co-morbid conditions,
3 - gauge effect that these symptoms have on her social functioning and ability to perform everyday tasks

general examination
1 - fitness for medical or surgical treatment.
2 - abdominal examination, looking for palpable bladder,
3 - renal angle tenderness and
4 - abdominal masses.

pelvic examination
1 - associated pelvic prolapse and
2 - size of uterus and ovaries.

Pelvic US: size and morphology of pelvic viscera

Upper tracts imaged by either intravenous urogram or an ultrasound of the kidneys, ureters and bladder to look for tumours and calculi

Definitive MX: depend upon what found on investigation, but almost certainly benefit from advice of continence advisor and supply of proper incontinence pads, rather than using sanitary towels.

19

Having excluded sinister underlying pathology, which of the following conservative measures are advisable?

1 - Bladder drill
2 -Referral to a continence advisor
3 -Increase fluid intake
4 - Reduce smoking
5 - Prophylactic antibiotics

1 - True
2 - True. Definitive management will depend upon what is found on investigation. This woman would almost certainly benefit from the advice of a continence advisor and a supply of proper incontinence pads

3 - False

4 - True

5 - False

20

A 45-year-old woman attends GOPD after saline cystometry has demonstrated urodynamic stress incontinence. She is contemplating undergoing a transvaginal midurethral tape procedure but requests further investigations as she is concerned about the risk of failure.

Which investigation could you offer her to give extra information on prognosis?

Cystoscopy under general anaesthetic
Electromyography
Nerve conduction studies
Pelvic ultrasound
Urethral pressure profilometry

The correct answer is urethral pressure profilometry. This is a test of urethral function and assesses the closure pressure of the urethra and, thus, the ability of the urethra to prevent leakage. This test is of limited value in isolation but has been found to confer some information about surgical success after continence surgery. A maximum urethral closure pressure (MUCP) <20 cm H20 has been associated with a worse functional outcome.

21

What findings of Pves, Pdet and Pabd indicate a diagnosis of urodynamic stress incontinence?

1 - Absence of peaks of pressure rise on running taps

2 - Peaks of pressure rise in Pves, Pdet and Pabd on coughing with leaking

3 - Peaks of pressure rise in Pves and Pdet but not in Pabd in filling phase

4 - Sharp rises in Pves and Pabd without rise in Pdet with leakage of urine on coughing

5 - Sharp rises in Pves and Pabd without rise in Pdet with no leakage of urine on coughing

Sharp rises in Pves and Pabd without rise in Pdet with leakage of urine on coughing
The answer is Sharp rises in Pves and Pabd without rise in Pdet with leakage of urine on coughing. Urodynamics findings in peaks of pressure rise in Pves and Pdet but not in Pabd in filling phase means a diagnosis of detrusor overactivity, sharp rises in Pves and Pabd without rise in Pdet with no leakage of urine on coughing shows a stable bladder with no USI (normal). Sharp rises in Pves and Pabd without rise in Pdet with leakage of urine on coughing show that the sharp rise in Pves is due to rise in Pabd due to coughing and leakage is consistent with the diagnosis of USI. Absence of peaks of pressure rise on running taps signifies stable bladder and Peaks of pressure rise in Pves, Pdet and Pabd on coughing with leaking shows a diagnosis of cough induced detrusor overactivity as there is peak of pressure rise in Pdet with leaking.
