Gynaecology Flashcards
1
Q
What is a pelvic organ prolapse?
A
- The descent of the pelvic organs into the vagina
- The prolapse is a result of weakness and lengthening of the ligaments and muscles surrounding the uterus, rectum and bladder
2
Q
What are the different types of prolapse?
A
- Uterine
- Vault
- Rectocele
- Cystocele
3
Q
What is a vault prolapse?
A
- When a women has had a hysterectomy and no longer have a uterus
- The top of the vagina (the vault) descends into the vagina
4
Q
What is a rectocele?
A
- They are caused by weakness in the posterior vaginal wall
- This allows the rectum to prolapse forward into the vagina
5
Q
What are the signs and symptoms of a rectocele?
A
- They are associated with constipation and women can develop faecal loading in the part of the rectum that has prolapsed
- The loading of faeces causes urinary retention due to compression on the urethra and a palpable lump in the vagina that can be pushed backwards
6
Q
What is a cystocele?
A
- Caused by a defect in the anterior vaginal wall allowing the bladder to prolapse backwards into the vagina
- Can also happen with the urethra (urethrocele) and a combined one is called a cystourethrocele
7
Q
What are the risk factors for developing pelvic organ prolaspe?
A
- Multiple vaginal deliveries
- Prolonged traumatic delivery
- Age
- Obesity
- Coughing/constipation strain
- Menopause
8
Q
What is the presentation of a pelvic organ prolapse?
A
A feeling of “something coming down” in the vagina
A dragging or heavy sensation in the pelvis
Urinary symptoms, such as incontinence, urgency, frequency, weak stream and retention
Bowel symptoms, such as constipation, incontinence and urgency
Sexual dysfunction, such as pain, altered sensation and reduced enjoyment
9
Q
How would you examine a pelvic organ prolapse?
A
- Dorsal and left lateral position
- A Sim’s speculum would be used to support opposing vaginal wall to one being examined
10
Q
What is the grading system and what are the grades for pelvic organ prolapse?
A
rade 0: Normal
Grade 1: The lowest part is more than 1cm above the introitus
Grade 2: The lowest part is within 1cm of the introitus (above or below)
Grade 3: The lowest part is more than 1cm below the introitus, but not fully descended
Grade 4: Full descent with eversion of the vagina
11
Q
What is the conservative management of pelvic organ prolapse?

Lifestyle changes for associated stress incontinence, such as reduced caffeine intake and incontinence pads
Treatment of related symptoms, such as treating stress incontinence with anticholinergic mediations
Vaginal oestrogen cream
12

urge incontinence
stress incontinence.
15
Q
What causes urge incontinence?
A

- Weight loss
- Pelvic floor exercises
- Duloxetine
19
Q
What is the management for urge incontinence?
A
- Anticholinergic medication, for example, oxybutynin, tolterodine and solifenacin
They have side effects which include dry mouth dry eyes, postural hypotension and can lead to cognitive decline
20
Q
What is an alternative treatment for urge incontinence?
A
Mirabegron but is a beta-3 agonist so raises BP
21
Q
What are the risk factors for developing kidney stones?
A
- Dehydration
- Previous kidney stones
- Stone forming foods
- Metabolic
- Systemic disease: Crohn’s disease (calcium oxalate stones)
- Metabolic:hypercalcaemia, hyperparathyroidism, hypercalciuria (calcium stones)
- Loop diuretics
22
Q
What are some stone forming foods?
A
- Chocolate
- Spinach
- Nuts
- Tea
23
Q
What are the most common types of kidney stones?
A
Calcium-based stones they account for 80%. Having a raised serum calcium and low urine output are key risk factors for calcium collecting into a stone
24
Q
What are the two types of calcium stone?
A
- Calcium oxalate (most common) results in a black or dark coloured stone.
- Calcium phosphate- results in a dirty white colour stone
25
What are some other types of kidney stones?
- **Uric acid:** red-brown in colour and not visible under an x-ray.
Risk factors: food high in purines e.g. shellfish, anchovies, red meat or organ meat, as uric acid is a breakdown product of purine
- Struvite- produced by bacteria (Proteus mirabilis, Proteus vulgaris, and Morganella morganii) therefore are associated with infection. Forms dirty white stones visible on X-ray.
- Cystine – associated with cystinuria, an autosomal recessive disease form yellow or light pink coloured stones not visible on x-ray
26
What causes struvite stones to form?
Bacteria release enzyme urase which causes ammonia to form. Ammonia makes urine more alkaline so favours the precipitation of phosphate, magnesium and ammonium.
These form jagged crystals called **Staghorns**
27
What is the cause of the pain associated with kidney stones?
- The peristaltic action of the collecting duct against the stone.
- Pain is worse at the uteropelvic junction and down the ureter pain subsides once stone gets to the bladder
28
What are the symptoms of renal stones?
- Acute severe flank pain: loin to groin pain that lasts minuets to hours . Fluctuating pain
- Nausea and vomiting
- Haematuria
- reduced urine output
29
What are some first-line investigations for renal stones?
- Urine dipstick can show blood
- FBC check kidney function and calcium levels
- X-ray can show calcium based stones but not uric
30
What is the gold standard test for renal stones?
- Non contrast CT scan of kidney, ureters and bladder (CT KUB) .
**Should be performed within 14 hours of admission**
May use ultrasound if radiation needs to be avoided
31
What is the best form of pain relief for renal stones?
- NSAIDs are typically used. IM diclofenac is most commonly used. Opiates are typically used as not good
32
What is the conservative/medical treatment for renal stones?
- Watchful waiting is usually used in stones less than 5mm, as there is a 50-80% chance they will pass without any interventions. It
- **Tamsulosin** is an alpha blocker that can be used to help passage of stones not indicated for renal more for ureteric
33
What are the surgical treatments for renal stones?
ESWL involves an external machine that generates shock waves and directs them at the stone under x-ray guidance. The shockwaves break the stone into smaller parts to make them easier to pass.
Ureteroscopy and laser lithotripsy:
A camera is inserted via the urethra, bladder and ureter, and the stone is identified. It is then broken up using targeted lasers, making the smaller parts easier to pass.
Percutaneous nephrolithotomy (PCNL):
PCNL is performed in theatres under a general anaesthetic. A nephoscopy (small camera on a stick) is inserted via a small incision at the patient’s back. The scope is inserted through the kidney to assess the ureter. Stones can be broken into smaller pieces and removed. A nephrostomy tube may be left in place after the procedure to help drain the kidney.
34
What is the advice for a patient suffering from recurrent renal stones?
- Increase oral fluids
- Reduce salt intake
- Reduce oxalate/urate rich food intake
- Avoid carbonated drinks
- Add lemon juice to waters
35
What medications can be used to reduce the risk of renal stone formation?
Potassium citrate in patients with calcium oxalate stones and raised urinary calcium
Thiazide diuretics (e.g., indapamide) in patients with calcium oxalate stones and raised urinary calcium
36
What are the complications of renal stones?
- **Obstruction and hydronephrosis**: acute kidney injury and renal failure
- **Urosepsis**: an infected, obstructing stone is a urological emergency and requires urgent decompression
37
What is Androgen insensitivity syndrome?
- It is a condition where cells are unable to respond to androgen hormones due to a lack of receptors.
- Patients with this condition are genetically male however the absent response to testosterone and the extra production of oestrogen leads to a female phenotype b
38
What type of genetic condition is Androgen insensitivity syndrome?
X-linked recessive
39
What anatomical features will someone with Androgen insensitivity syndrome have?
- They will have testes in the abdomen or inguinal canal
- They will not have a uterus, upper vagina, cervix, fallopian tubes and ovaries.
- This is because the testes produce **anti Mullerian hormone** which prevents them from forming
40
What other features will someone with Androgen insensitivity syndrome have?
- Lack of pubic and facial hair and male muscle development
- Will be taller than average female
- They are infertile and there is an increased risk of testicular cancer
41

45
What is menopause?
- A retrospective diagnosis made after a woman has had no periods for 12 months
- It is defined as a permanent end to menstruation
- Menopause is the point at which menstruation stops
46
What is perimenopause, postmenopausal and premature menopause?
- Perimenopause refers to the time around the menopause, where the woman may be experiencing vasomotor symptoms and irregular periods.
- Postmenopausal describes the period from 12 months after the final menstrual period onwards.
- Premature menopause is menopause before the age of 40 years. It is the result of premature ovarian insufficiency.
47
What causes menopause?
- It is caused by a lack of ovarian follicular function, resulting in changes in the sex hormones associated with the menstrual cycle
- Oestrogen and progesterone levels are low
- LH and FSH levels are high in response to an absence of negative feedback from oestrogen
48
Describe how oestrogen is released during the menstrual cycle ?
- In the ovaries the process of primordial follicles maturing is into primary and secondary follicles is always occurring
- At the start of the menstrual cycle FSH stimulates the further development of secondary follicles
- As the follicles grow the **granulosa cells** that surround them secrete increasing amounts of oestrogen
49
How does the menopause begin?
- The menopause begins with a decline in the development of ovarian follicles
- Without the growth and development of the follicles there is reduced production of oestrogen
- This results in increasing levels of LH and FSH as oestrogen has a negative feedback on these hormones in the pituitary gland
50
How is the menstrual cycle affected in the menopause?
- Falling follicular development means ovulation does not occur (anovulation)
- Without oestrogen the endometrium does not develop leading to a lack of menstruation (Amenorrhoea)
- The low levels of oestrogen lead to the perimenopausal symptoms
51
What are the perimenopausal symptoms?
- Hot flushes
- Emotional lability or low mood
- Premenstrual syndrome
- Irregular periods
- Joint pains
- Heavier or lighter periods

52
What does a lack of oestrogen increase the risks of?
- CVD
- Osteoporosis
- Pelvic organ collapse
- Urinary incontinence
53
How can menopause be diagnosed?
- Symptoms without blood test
- Use FSH blood test in women under 40 or aged 40-45 with menopausal symptoms
54
How long do women need to use contraception for after the menopause?
- Two years after the last menstrual period in women under 50
- One year after the last menstrual period in women over 50
55
What is the management of perimenopausal symptoms?
Hormone replacement therapy (HRT)
Tibolone, a synthetic steroid hormone that acts as continuous combined HRT (only after 12 months of amenorrhoea)
Clonidine, which act as agonists of alpha-adrenergic and imidazoline receptors
Testosterone can be used to treat reduced libido (usually as a gel or cream)
Vaginal oestrogen cream or tablets, to help with vaginal dryness and atrophy (can be used alongside systemic HRT)
Vaginal moisturisers, such as Sylk, Replens and YES
56
What can be used to help with the vasomotor symptoms of the menopause?
Clonidine which is a alpha-2 agonist
57
What are the indications of HRT?
Replacing hormones in premature ovarian insufficiency, even without symptoms
Reducing vasomotor symptoms such as hot flushes and night sweats
Improving symptoms such as low mood, decreased libido, poor sleep and joint pain

When does Asherman’s syndrome usually occur?
- It happens following damage to the uterus and often happens after a pregnancy related **dilation and curettage procedure**
- For example retained products of conception (removing placental tissue left behind after birth). It can also occur after uterine surgery (e.g. myomectomy) or several pelvic infection (e.g. endometritis).
69
What happens as a result of the adhesions Asherman’s syndrome?
- The damage endometrium forms scar tissue which connects areas of the uterus that are not usually connected
- These adhesions may bind the uterine walls together or the endocervix sealing it shut
- These adhesions form physical obstructions and distort the pelvic organs
70
What are the symptoms Asherman’s syndrome?
- Secondary amenorrhoea
- Significantly lighter periods
- Dysmenorrhoea
- Infertility
If a patient is asymptomatic then it is not classified as Asherman’s syndrome

Hysteroscopy is the gold standard investigation, and can involve dissection and treatment of the adhesions
Hysterosalpingography, where contrast is injected into the uterus and imaged with x-rays
Sonohysterography, where the uterus is filled with fluid and a pelvic ultrasound is performed
MRI scan
**Management is dissecting the adhesions during hysteroscopy**

109
Why is T2DM a risk factor for endometrial cancer?
Insulin may stimulate the endometrial cells and increase the risk of endometrial hyperplasia and cancer.
PCOS is also associated with insulin resistance and increased insulin production. Insulin resistance further adds to the risk of endometrial cancer in women with PCOS.
110
What are some protective factors for endometrial cancer?
- Combined pill
- Mirena coil
- Increased pregnancies

- As prolactin inhibits the production of GnRH
135
What is a risk of secondary amenorrhoea?
Osteoporosis
Ensure adequate vitamin D and calcium intake
Hormone replacement therapy or the combined oral contraceptive pill
136
What is endometriosis?
- Where there is ectopic endometrial tissue outside the uterus
-Endometrial tissue outside the uterus is described as an **endometrioma**.
- .Endometriomas in the ovaries are often called “chocolate cysts”.
- Adenomyosis refers to endometrial tissue within the myometrium
- In females over 17 years of age endometriosis should be considered for if symptoms have been present for over 6 months
137
What is believed to cause endometriosis?
- Retrograde menstruation when endometrial tissue flows back into the fallopian tubes
- Embryonic cells remain outside the uterus
- Lymphatic system spread of endometrial cells
- Metaplasia of the cells to endometrial cells
138
What is the pathophysiology of endometriosis?
- The cells outside of the uterus respond in the same way as the ones in the uterus
- This causes inflammation of tissue around the site of the endometriosis
- Can lead to adhesions which causes chronic non-cyclical pain. These can also lead to reduced fertility
- Can also deposit in the bladder or bowels leading to blood in urine or stools
139
What are the symptoms of endometriosis?
The main symptom if **cyclical pelvic pain**.
- Deep dyspareunia (pain on deep sexual intercourse)
- Dysmenorrhoea (painful periods)

A fixed cervix on bimanual
Tenderness in the vagina, cervix and adnexa
141
How would you diagnose Endometriosis?
- Pelvic ultrasound may reveal endometriomas and chocolate cysts but are often unremarkable so need to be referred for laparoscopy

142
What is the initial management for endometriosis?
- Establish diagnosis and explain it to patient
- Analgesia
143

Mirena coil
**All these methods will stop ovulation and reduce endometrial thickening**
GnRH agonists (goserelin)- will induce a menopause like state
144
What are the surgical options for endometriosis?

- They are oestrogen sensitive meaning they grow in response to oestrogen
146
What are the different types of fibroids?
Intramural means within the myometrium (the muscle of the uterus). As they grow, they change the shape and distort the uterus.
Subserosal means just below the outer layer of the uterus. These fibroids grow outwards and can become very large, filling the abdominal cavity.
Submucosal means just below the lining of the uterus (the endometrium).
Pedunculated means on a stalk.
147
What is the presentation of fibroids?
Heavy menstrual bleeding (menorrhagia) is the most frequent presenting symptom
Prolonged menstruation, lasting more than 7 days
Abdominal pain, worse during menstruation
Bloating or feeling full in the abdomen
Urinary or bowel symptoms due to pelvic pressure or fullness
Deep dyspareunia (pain during intercourse)
Reduced fertility
148
What are the investigations for fibroids?
Hysteroscopy is the initial investigation for submucosal fibroids presenting with heavy menstrual bleeding.
Pelvic ultrasound is the investigation of choice for larger fibroids.
MRI scanning may be considered before surgical options, where more information is needed about the size, shape and blood supply of the fibroids.
149

- Sudden onset constant severe unilateral pelvic pain associated with nausea and vomiting
- Pain is not always severe and can come and go
- On examination there will be localised tenderness there may be a palpable mass absence does exclude the diagnosis
171
What is used to diagnose an ovarian torsion?
Pelvic ultrasound is the initial investigation of choice. Transvaginal is ideal,
Will show a **whirlpool sign, free fluid** in pelvis and oedema of the ovary
Definitive diagnosis is made with laparoscopic surgery

Hyperandrogenism refers to the effects of high levels of androgens
Hirsutism refers to the growth of thick dark hair, often in a male pattern, for example, male pattern facial hair
Insulin resistance refers to a lack of response to the hormone insulin, resulting in high blood sugar levels
176

Why is insulin resistance a key part of PCOS?
- Insulin resistance(means more insulin is released) causes greater release of androgens for the the ovaries and adrenal glands as insulin stimulates the release
- Insulin also suppresses sex hormone-binding globulin (SHBG) production by the liver. SHBG normally binds to androgens and suppresses their function. Reduced SHBG further promotes hyperandrogenism in women with PCOS.
- This contributes the halting the development of the follicles in the ovaries leading to anovulation

- Mobile
- Fluctuant
They require further assessment to exclude cancer
207
What is fat necrosis?
Fat necrosis causes a benign lump formed by localised degeneration and scarring of fat tissue in the breast. It at necrosis is commonly triggered by localised trauma, radiotherapy or surgery, with an inflammatory reaction resulting in fibrosis and necrosis (death) of the fat tissue. It does not increase the risk of breast cancer.
On examination, fat necrosis can be:
Painless
Firm
Irregular
Fixed in local structures
There may be skin dimpling or nipple inversion
Ultrasound or mammogram can show a similar appearance to breast cancer. Histology (by fine needle aspiration or core biopsy) may be required to confirm the diagnosis and exclude breast cancer.
After excluding breast cancer, fat necrosis is usually treated conservatively. It may resolve spontaneously with time. Surgical excision may be used if required for symptoms.

How successful is the COCP?
More than 99% effective with perfect use and 891% effective with typical use
249
What age is the COCP licensed up to?
50
250
How does the COCP work?
- Prevents ovulation
- Progesterone thickens cervical mucus
- Progesterone inhibits the proliferation of the endometrium reducing chances of successful implantation
251
How do oestrogen and progesterone work in the COCP?
- Negative feedback on the hypothalamus and pituitary suppressing the release of GnRH, LH and FSH.
- Without LH and FSH ovulation does not occur
- With the COCP the lining of the endometrium is maintained in a stable state, will then have a withdrawal bleed when the pill is stopped
252
What are the two types of COCP and which are the main ones used?
Monophasic pills contain the same amount of hormone in each pill
Multiphasic pills contain varying amounts of hormone to match the normal cyclical hormonal changes more closely
The NICE Clinical Knowledge Summaries (2020) recommend using a pill with levonorgestrel or norethisterone first line (e.g. Microgynon or Leostrin). These choices have a lower risk of venous thromboembolism.
**Microgeon or Loestrin**
253
What are the side effects of COCP?
Unscheduled bleeding is common in the first three months and should then settle with time
Breast pain and tenderness
Mood changes and depression
Headaches
Hypertension
Venous thromboembolism (the risk is much lower for the pill than pregnancy)
Small increased risk of breast and cervical cancer, returning to normal ten years after stopping
Small increased risk of myocardial infarction and stroke
254

- Uncontrolled hypertension
- Migraine with aura
- History of VTE
- Aged 35 and smoking 15 cigarettes a day
- Surgery
- Vascular disease
- IHD

255
How long after taking the pill are you protected?
- If started on day 1-5 of menstrual cycle then protection is immediate
- If started after this then it takes 7 days to have protection
256
What to do if you miss a COCP pill?
Missing a pill is when one pill is more than 24 hours late e.g 48 hours since last pill was taken
- If missed but within 72 hours of when last taken then take as soon as possible and no additional protection is required
- Missing more than one pill (more than 72 hours since the last pill was taken):
Take the most recent missed pill as soon as possible (even if this means taking two pills on the same day)
Additional contraception (i.e. condoms) is needed until they have taken the pill regularly for 7 days straight
If day 1 – 7 of the packet they need emergency contraception if they have had unprotected sex
If day 8 – 14 of the pack (and day 1 – 7 was fully compliant) then no emergency contraception is required
If day 15 – 21 of the pack (and day 1 – 14 was fully compliant) then no emergency contraception is needed. They should go back-to-back with their next pack of pills and skip the pill-free period.
257

- Desogestrel only pill : can't be delayed for more than 12 hours
259
How do the two types of POP work?
Traditional progestogen-only pills work mainly by:
Thickening the cervical mucus
Altering the endometrium and making it less accepting of implantation
Reducing ciliary action in the fallopian tubes
Desogestrel works mainly by:
Inhibiting ovulation
Thickening the cervical mucus
Altering the endometrium
Reducing ciliary action in the fallopian tubes
260
How long does POP take to become affective?
If started on days 1-5 then protection starts immediately
If taken after day 1-5 then protection takes 48 hours. Causes no harm in pregnancy so can be started without need to check
261

How does FSH stimulate the development of secondary follicles?
The follicles grow and the granulosa cells secrete increasing amounts of oestrogen.
This has a negative feedback on the pituitary reducing the quantity of LH and FSH
The rising oestrogen also causes the cervical mucus to become more permeable allowing sperm to penetrate the cervix

What happens before ovulation?
- One of the follicles will develop further than the others and become the dominant follicle
- LH spikes (and FSH to some degree) and this causes the dominant follicle to release the ovum

What happens at the beginning of the luteal phase once the ovum has been released?
- The follicle become the corpus luteum which secretes high levels of progesterone which maintains the endometrial lining
- It also causes the cervical mucus to become thick and no longer penetrable
- When fertilisation occurs HCG maintains the corpus luteum

What happens if there is no fertilisation of the ovuM?
