Q

Urine filters from the kidneys down to the bladder through the ureters and then is removed from the bladder via the urethra. What is the name of the special type of muscle that the bladder is composed of?

1 - psoas muscle
2 - detrusor muscle
3 - inguinal muscle
4 - pelvic muscle

A

2 - detrusor muscle
- this is able to stretch as the bladder fills

Q

When the micturition centre in the spinal cord is stimulated at S2-S4 by stretch receptors in the bladder, does this affect the sympathetic or parasympathetic system?

A
  • both
  • part of micturition reflex
  • decreases sympathetic and increased parasympathetic

Q

When the micturition centre in the spinal cord is stimulated at S2-S4 by stretch receptors in the bladder this reduces the sympathetic and increases the parasympathetic activity, all part of the micturition reflex. Does this cause the detrusor muscle to contract or relax?

A
  • contract as in rest and digest = parasympathetic

Q

When the micturition centre in the spinal cord is stimulated at S2-S4 by stretch receptors in the bladder this reduces the sympathetic and increases the parasympathetic activity, all part of the micturition reflex. Does this cause the internal sphincter to contract or relax?

A
  • relax and allow urine to leave the bladder
  • as in rest and digest = parasympathetic
  • has a moderate effect on relaxing the external sphincter as well

1 - hippocampus
2 - pons
3 - midbrain
4 - medulla

Q

If we want to urinate does the pontine micturition centre or pontine storage centre override the micturition reflex and stop us from urinating?

A
  • pontine storage centre
  • as in it stores the urine
  • if we want to urinate the pontine micturition centre allows for the micturition reflex to occur

Q

There are lots of different types of incontenance. What is urge incontenance?

1 - small leakage of urine occurs on physical exertion due to stress on bladder

Q

There are lots of different types of incontenance. What is outflow incontenance?

18
Q

There are lots of different types of incontenance. What is overflow incontenance?

1 - small leakage of urine occurs on physical exertion due to stress on bladder
2 - unable to control urination due to involuntary bladder contractions and then urination
3 - urethra and flow of urine is blocked
4 - both urge and stress incontenance
5 - bladder fills but does not empty properly causing continuous dribbling

A

5 - bladder fills but does not empty properly causing continuous dribbling

  • continuous dribbling or symptoms of stress incontinence with large post-void residual volume
  • can be caused by recurrent UTIs
  • made worse by constipation or anticholinergics
  • often occurs in men with prostatic obstruction
19
Q

There are lots of different types of incontenance. What is functional incontenance?

1 - small leakage of urine occurs on physical exertion due to stress on bladder
2 - inability to reach and use the toilet
3 - urethra and flow of urine is blocked
4 - both urge and stress incontenance
5 - bladder fills but does not empty properly causing continuous dribbling

A

2 - inability to reach and use the toilet
- may be due to frailty or disability

20
Q

All of the following are causes that can accentuate a patients incontenance, EXCEPT which one?

1 - bowel function (constipation)
2 - mobility/dexterity (unable to reach the toilet)
3 - medication
4 - nutrition
5 - medical conditions
6 - psychological conditions

A

4 - nutrition

  • most of these causes can be treated if clinician is aware of them
21
Q

When conducting a history with a patient, in reference to their urination habits, which of the following are RED flags to be aware of?

1 - Haematuria
2 - Persistent UTI
3 - Constitutional symptoms
4 - Poor renal function
5 - Abnormal neurology include saddle anaesthesia
6 - Recent back trauma or pelvic surgery
7 - all of the above

A

7 - all of the above

22
Q

When managing a patient with urinary incontenance the treatment can be divided into 4 sections:

  • Lifestyle advice/patient education
  • MDT/non-pharmacological
  • Medical management
  • Surgical management

Which of the following is NOT a lifestyle intervention for incontenance?

1 - Smoking cessation
2 - Reduced fluid intake at specific times
3 - Weight reduction
4 - Managing constipation
5 - Reduce alcohol and caffeine intake
6 - Botulinum toxin

A

6 - Botulinum toxin
- limits detrusor muscle contractions

23
Q

In some patients the use of anti-muscarinics can be used. These act by competitively binding against ACh, therefore reducing parasympathetic activity and detrusor muscle contraction. Which of the following is the core anti-muscarinic that we need to be aware of used to treat urinary incontenance?

1 - bisoprolol
2 - doxazosin
3 - digoxin
4 - solifenacin

A

4 - solifenacin

24
Q

Solifenacin an anti-muscarinics that competitively binds against ACh, reducing parasympathetic activity and detrusor muscle contraction. However, it has a large adverse events profile, especially in the elderly. Which of the following are common?

1 - cognitive impairment, hallucinations
2 - blurred vision
3 - dry mouth
4 - tachycardia
5 - nausea, constipation
6 - urinary retention
7 - all of the above

A

7 - all of the above
- all are associated with the inhibiting the parasympathetic system

25
Q

In males who experience benign prostate hyperplasia (BPH), medications can limit this. Which drug is typically prescribed for this, and is a core drug for us?

1 - bisoprolol
2 - doxazosin
3 - digoxin
4 - solifenacin

A

2 - doxazosin
- tamsulosin is also common
- both are alpha blockers that reduces smooth muscle tone in the prostate

  • transurethral resection of the prostate (TURP) is also a surgical option for BPH

28
Q

Typically in older patients, the diagnosis of constipation is less than how many bowel movements in 1 week?

Q

When performing a history with a patient, which of the following is NOT a RED flags to be aware of?

A

1 - overflow diarrhoea

31

Some basic lifestyle advice for patients with constipation is increased fluid intake, high fibre diet, increase activity and encourage mobilisation. However, if this is infective we can perform which of the following?

1 - enema
2 - suppositories
3 - disimpaction
4 - all of the above

A

4 - all of the above
