When is an episiotomy required?
- Normally used to prevent further tearing or prevent tearing occuring at all
- Sometimes need to expedite the birth if the women is getting exhausted
- Creates space for shoulder dystocia
- May be required for normal birth /forceps delivery
- May have a spontaneous tear
What are the degrees of episiotomy?
- Vaginal mucosa
- Towards perineal muscles
- External anal sphincter
- Internal anal sphincter
Definition of ceasarian section? Risks?
Defined as delivery of the fetus through incision in the abdominal wall & uterine wall
- Bladder injury 1 in 1000
- Uteritic injury 1 in 10000
What is a hysterectomy? Reasons for procedure?
Surgical removal of the uterus
- Fibroids, post partum haemorrhage, malignancy
What is the course of the ureter?
- Crosses over bifurcation of the common iliac vessels
- Runs retroperitoneally on the lateral pelvic wall
- At the level of the ischial spine, turns forward and medially
- Crossed by the uterine artery
- Passes about 2 cm lateral to the cervix and in front of the lateral border of the vagina.
- Enters the back of the bladder
Which ureter/kidney is more effected by dilatation in pregnancy?
Right
What are fibroids?
The commonest benign tumour arising from the myometrium, mainly affecting smooth muscle
SSx with fibroids?
Often assymptomatic but may present with dysmenorrhoea, menorrhagia, pressure symptoms and pain
Management of fibroids?
- Symptom relief
- Hormonal vs intervention
- Myomectomy (surgical removal of fibroids)
- Hysterectomy
- Uterine artery embolization
- GnRH analogues
What is endometriosis?
Chronic inflammatory condition defined by endometrial stroma and glands found outside the uterine cavity.
Most common sites are pelvic peritoneum and ovaries.
What are the symptoms in endometriosis [and reasons for the symptoms]?
- Endometriotic tissues detach and bleed: resulting in internal bleeding
Symptoms
- Presence of risk factors
- Dysmenorrhoea
- Chronic pelvic pain
- Dyspareunia (painful sex)
- Sub-fertility
Management of endometriosis?
Fertility not desired: pain without endometrioma or suspected severe disease.
- Oral contraceptive pill, adjunct NSAID
Fertility not desired: pain with endometrioma or suspected severe disease
- Surgery adjunct, post surgery hormonal therapy
Immediate fertility desired
- Controlled ovarian hyperstimulation
- IVF
What is a radical hysterectomy?
A radical hysterectomy is the removal of the womb, cervix, tissue around the cervix (parametrium) and upper part of the vagina. The pelvic lymph nodes are usually removed as part of this operation.
