Q

Incontinence - what is the management of urge incontinence (OAB)?

A
  1. Bladder retraining
  2. Bladder stabilising drugs, 1st line are antimuscarinics - OXYBUTYNIN, TOLTERODINE (both immediate release), DARIFENACIN (once daily prep)
  3. MIRABEGRON (Beta3 agonist) - useful if concern about anticholinergic side effects in frail patients, works by relaxing detrusor and increasing bladder capacity
  4. Surgery - botox, bypass, bladder drill

Q

Incontinence - what is the management for stress incontinence?

A
  1. Pelvic floor training, 8 contractions, 3 times a day, minimum 3 months
  2. DULOXETINE
  3. Surgery - retropubic mid-urethral tape procedures, colposuspension, surgery is aimed at restoring pressure transmission to urethra

17
Q

Ectopic Pregnancy - what are the symptoms?

A

Unilateral lower abdo pain

Amenorrhea

Vaginal bleeding

Shoulder tip pain - blood in peritoneum irritates diaphragm, causing shoulder tip pain

D+V

Pelvic pain

18
Q

Ectopic Pregnancy - what are the investigations?

A

Serum hCG testing

Transvaginal US

Vital signs

19
Q

Ectopic Pregnancy - when would you do expectant management and what does expectant management entail?

A

Expectant management - closely monitor patient over 48h, if B-hCG levels rise again or symptoms manifest -> intervention

You would choose expectant management when:

  1. Size <35mm
  2. Unruptured, aymptomatic
  3. No fetal heartbeat
  4. Serum B-hCG <1,000IU/L
20
Q

Ectopic Pregnancy - when would you do medical management and what does medical management entail?

A

Medical management - Methotrexate

You would do medical management when:

  1. Size <35mm
  2. Unruptured
  3. No fetal heartbeat
  4. Serum B-hCG <1,500IU/L

Can’t do medical management if there is another intrauterine pregnancy

21
Q

Ectopic Pregnancy - when would you do surgical management and what does surgical management entail?

A

Surgical management - salpingectomy, salpingotomy

You do surgical management if:

  1. Size >35mm
  2. Can be ruptured
  3. Pain
  4. Visible fetal heartbeat
  5. Serum B-hCG >1,500IU/L

34
Q

Miscarriage - what is the gold standard investigation? What other investigation should you do?

A

Transvaginal US

Serum hCG - exclude ectopic

35
Q

Miscarriage - what are the three types of management and what do they entail?

A

Expectant management:

  1. Waiting for spontaneous miscarriage
  2. 1ST LINE. involves waiting 7-14 days for miscarriage to complete spontaneously
  3. Unsuccessful - medical or surgical

Medical management:

  1. Vaginal Misoprostol - prostaglandin analogue, binds to myometrial cells, cause strong myometrial contractions to expel tissue
  2. Give antiemetics and pain relief too

Surgical management:
1. Vacuum aspiration (suction curettage)

36
Q

Miscarriage - expectant management is 1st line in miscarriage treatment, unless one or more of 4 factors are present, what are they?

A
  1. Increased risk of bleeding
  2. Previous adverse events in pregnancy
  3. Increased risk from effects of haemorrhage
