Q

What are the three superficial landmarks of the female perineum?

A

Pubic symphysis, ischial tuberosity and coccyx.

17
Q

Which vessels anastomose with the vaginal arteries to form the blood supply to the lower third of the vagina?

A

Uterine artery

18
Q

What is the ovary attached to?

A

Broad ligament by a sleeve of peritoneum (mesovarium).

19
Q

What is an abdominal x-ray used for?

A

Used to investigate:

  • Kidney and bladder stones
  • Gall stones
  • Intestinal blockage or perforation
  • Ingested foreign objects
20
Q

What is a CT scan use for?

A 
Used to investigate:
- Infection
- Inflammation 
- Cancer
- Injury
- Kidney and bladder stones
- Abdominal aortic aneurysms 
Great to answer acute questions as it provides greater detail than x-rays, especially soft tissue and vessels.
21
Q

What are MRIs used for?

A 
Used to investigate:
- Tumours 
- Liver cirrhosis
- Inflammation
- Vessel malformation
Provides detailed soft tissue imagine however it is time consuming and expensive.
22
Q

What are ultrasounds used for?

A 
Used to investigate:
- Pain and distension
- Abnormal organ function
- Kidney and gall stones
- Abdominal aortic aneurysm 
- Blood flow through vessels (Doppler) 
- Monitor the foetus in pregnancy 
Not useful for air-filled organs or large patient with fat as this weakens the imagine. Not as good detail as CT/MRI but it is cheap, quick and real-time.
23
Q

What is angiography used for?

A 
Used to investigate:
- AAA
- Aortic or renal artery stenosis 
- Blockages 
Can also be used in interventions.
24
Q

What is urography used for?

A

Used to investigate:

  • Haematuria
  • Kidney and bladder stones (first line)
  • Cancer
25
Q

What is a colonoscopy typically used for?

A

To investigate lower GI bleeding, common in the diagnosis of colon cancer or IBD. It can also be used to investigate further about acute or chronic diarrhoea.

26
Q

What is a UGI endoscopy?

A

Esophagogastroduodenoscopy

27
Q

What is a UGI endoscopy used for?

A
  • Upper GI bleed
  • Persistent dyspepsia
  • Heart burn and chronic acid reflux
  • Dysphagia
  • IBD (can be therapeutic)
28
Q

What is dyspepsia?

A

Indigestion

29
Q

In a digital rectal examination, what structure needs to be palpated to carry out a pudendal nerve block?

A

Ischial spine

30
Q

31
Q

Right posterolateral herniation of the L2 vertebra will cause pain in what region?

A

32
Q

Which structure creates the roof of the inguinal canal?

A

Overarching fibres of the internal oblique.

33
Q

A

Deep external pudendal artery.

34
Q

Which structure is used to assess the width of the true pelvic during childbirth?

A

Distance between sacral promontory to superior side of pubic symphysis.

35
Q

A 40 year old man has abdominal pain and blood in the stool, what is the most appropriate test to carry out?

A

Colonoscopy

36
Q

Describe the position of a femoral hernia relative to the pubic tubercle.

A

Below and lateral to the pubic tubercle.

37
Q

What are the four portosystemic anastomoses?

A
  • Oesophageal vein (syst) and left gastric vein (port)
  • Inferior rectal vein (syst) and superior rectal vein (port)
  • Epigastric vein (syst) and paraumbilical vein (port)
  • Retroperitoneal vein (syst) and visceral vein (port)
38

A

Local pain near the spine.

39
Q

Where does posterolateral herniation of lumbar vertebrae cause pain?
