While you are dissecting on the medial aspect of the psoas muscle at the level of the pelvic brim, which of
the following structures is most likely to be injured?
a. External iliac vein
b. External iliac artery
c. Ureter
d. Genito-femoral nerve
e. Obturator nerve
Answer: E (probably best answer – C next best)
– the obturator nerve descends
through the psoas major muscle, leaving the MEDIAL border of the muscle at the LEVEL of the PELVIC
BRIM. However, it does say that it is more likely to be damaged in the lower pelvis where it lies in extraperitoneal fat and is liable to damage during operations to remove pelvic lymphatics.

d. Gastroepiploic artery
e. Median sacral artery
D
Pubourethral ligament contains?
a. collagen
b. collagen, elastin
c. collagen, elastin, muscle
C
Histologically the ligaments consist of smooth muscle, elastin, collagen, nerves and, blood vessels
In anatomical position, the angle of the vagina is upwards and backwards**
a. 90 degrees
b. 135 degrees
c. 260 degrees
d. 310 degrees
B
Where does the paravaginal fascia insert?
a. Arcus tendineus
b. Iliopectineal line
c. Urogenital diaphragm
d. Perineal body
e. Sacrospinous ligament
A
The structure posterior to the external iliac artery and vein and would dissect medially off the psoas
muscle is:
a. Superior gluteal artery
b. Obturator nerve
c. Ureter
d. Uterine artery
Likely C
Probably ureter as the obturator nerve lies very deep to the external iliac artery, despite the ureter not
being truly posterior to the external iliac artery
How many oocytes are left by the time a woman reaches puberty?

Which of the following conditions require urgent surgical treatment?
a. acute appendicitis

c. acute pancreatitis
d. acute pyelonephritis
e. acute osteomyelitis
A
60 yo with several year history of LIF pain. Temp 38, raised WBC (15,000), few WBC in urine, unwell. Most
likely diagnosis?
a. acute appendicitis
b. acute cholecystitis
c. acute diverticulitis
C
Effect of electrosurgical waveform with high current, low voltage and increase tissue temperature rapidly
(>100 degrees to result in vaporization)**
a. Cut
b. Fulguration
c. Coagulation
d. Blend
e. Desiccate
A
After a vaginal hysterectomy, the patient is brought back to theatre for primary haemorrhage. In ligating
the internal iliac arteries, which of the following structures is most likely to be injured?
a. external iliac arteries
b. external iliac veins
c. ureters
d. obturator nerve
e. common iliac arteries
Most likely B, possibly C
a. external iliac arteries (lateral and should not come into play)
b. external iliac veins (most likely answer – will sit just infero-lateral to internal iliac and is
bulbous at level of bifurcation)
c. ureters (always in play even with a gynaecologist doing neurosurgery, but crosses internal iliac
from medial to lateral and should be below it at level of internal iliac)
d. obturator nerve (you are going medial to psoas and so are far enough away from the nerve)
e. common iliac arteries (should be below it at level of internal iliac)
Difficult endometriosis TAH. Sudden profuse bleeding from L paracervical tissue. Mx?
a. large clamp laterally
b. pack and call for help
c. clamp aorta above pelvic brim
d. clamp common iliac
e. finger to occlude common iliac then identify ureter

a. Antibiotics
b. V/Q
c. Pulmonary angiogram
d. Blood transfusion
B
Raised temp 12-24 hrs following TAH?
a. vault cellulitis
b. septicaemia
c. DVT
d. Reaction to transfusion
B
A 30 yo with TAH for intraepithelial Ca of the cervix. Flushed, temp 39 C, PR 140/min, RR 24, clear chest.

a. return to theatre
b. commence on antibiotics
c. apply pressure dressing
d. perform an IVP
e. no treatment needed
D - intravenous pyelogram
5 days post TAH, vertical incision, serous ooze, Mx?
a. nothing
b. Steristrip
c. antibiotics
d. probe
D - probe with swab
A TAH, BSO was performed for extensive endometriosis. The operation took approximately 2 hours. On
day 1 post op review, the patient c/o numbness on the anterior aspect of the right thigh and weakness on
flexion of the right hip. Which of the following is most likely?
a. patient has a psoas haematoma
b. pressure effect of the retractor during the long operation
c. patient has a pelvic haematoma
d. your assistant has been leaning on the thigh
e. Duplex Doppler to exclude DVT
B
Difficult hysterectomy with endometriosis, significant blood loss of 2 litres throughout the procedure. At
the end of the procedure is noted to have a haemostatic suture too close to what you thought was the
ureter. Your next options are:
a. Do nothing but closely observe in the next couple of days
b. Remove the suture
c. IV indigo carmine and watch the dye through the ureter
d. Do a cystotomy at the operation and pass some catheters up the bladder to make sure the
ureter is patent
D - but cystoscopy is probably more appropriate
Difficult TAH for endometriosis, difficulty with haemostasis. Finally haemostasis secured but stitch
uncomfortably close to left ureter at top of vaginal vault.
a. Do nothing, observe closely post-op
b. Ureterotomy at level of pelvic brim and insert ureteric stent
c. Cystotomy and insert stent into left ureter
d. Injection of indigo carmine IV and follow dye flow through ureter
e. Remove suture

At end of TAH there is fluid in pelvis that looks like urine. What do you do?
