Q

what causes the pain in the menstrual cycle? *physiology

A

The endometrial cells are sensitive to this decline in progesterone, and respond withprostaglandinrelease causing,
- Spiral artery vasospasm–leading to ischaemic necrosis and shedding of the superficial layer of the endometrium

-Increased myometrial contractions

Q

what are the mechanism of action of the non hormonal methods of management of menorrhagia?

A
  • tranexamic acid: inhibits activation of plasminogen and stabilises clot preventing breakdown

27
when do you refer a woman to secondary care for infertility?
- less than 36 the history, examination and investigations are normal in both partners and the couple have not conceived after 1 year - earlier if previous surgery, PID, STI hx,, abnormal pelvic exam, cancer tx etc
28
how is female infertility investigated in secondary care?
*tubal patency testing - hysterosalpingography - screens for tubal occlusion - if known comorbidities Diagnostic laparoscopy and dye
29

- lifestyle for weight, stress - medical: clomifene, gonadotropins, dopamine agonists - surgical: tubal microsurgery, laparoscopies
30
what are some causes of male infertility?
- primary spermatogenic failure - genetics with kleinfelters, androgen insensitivity - obstructive azoospermia with b/L seminal duct obstruction - varicocele - hypogonadism - chemo etc
31
how is Male infertility investigated in primary care?
- semen analysis first line - if first analysis abnormal → repeat offered ideally 3m after initial test allowing for spermatazoa cycle to be completed - Repeat testing may be required sooner than 3 months if a severe - chlamydia screen
32
when would you refer male infertility to secondary care?
referral to secondary following 2 abnormal semen analysis earlier if, - Previous genital pathology - Previous urogenital surgery - Previous STI - Varicocele - Significant systemic illness - Abnormal genital examination - Known reason for infertility e.g. previous cancer treatment
33
how is male infertility investigated in secondary care?
- Genetic testing - Sperm culture - Endocrine tests e.g. FSH and testosterone - Imaging of the urogenital tract - Testicular biopsy
34
how is male infertile managed?
lifestyle: weight, stress, smoking and alcohol medical: gonadotropins if hypogonadism surgical: obstructive causes
35
how is infertility in general managed?
- clomifene - tubal microsurgery - IVF - counselling before, during and after fertility testing
36
what advice might you give to a couple trying to conceive?
- Regular (every 2-3 days) sexual intercourse throughout the woman’s cycle - Preparation for pregnancy e.g. taking preconceptual folic acid (400mcg daily) - Smoking cessation advice to both men and women that smoke - Avoidance of drinking alcohol excessively - Women should aim for a BMI of 19-25 kg/m2
37
what is dyspareunia ?
recurrent or persistent pain within the genital or pelvic region associated with sexual intercourse - experience pain just before, during, or after sexual intercourse, or other sexual activities
38
what might be the pathophysiology of female dyspareunia?
- lack of lubrication in post-menopausal - oral contraception with oestrogen, progestin - endometriosis - alterations to vaginal anatomy - skin diseases
39
what might be male specific pathophysiology of dyspareunia?
Peyronie disease - scar tissue on tunica albuginea - pathological curvature of penis
40
what are common causes for dyspareunia for male and females?
genitourinary infections (e.g., urethra, prostate, seminal vesicles, or bladder) sexually transmitted infections (e.g., gonorrhoea, chlamydia) psychological factors
41
how might dyspareunia present?
- females - pain at entrance to vagina, in abdomen or near cervix during penetration - males - erection, irritation of skin on penis with rash formation - sharp, or dull and throbbing pain - burning pains, pelvic cramping, or muscle tightness or spasms
42
how might you examine dyspareunia?
- pelvic exams - visual: labia for ulcers, fissures, labial hypertrophy, vaginal agenesis and imperforate hymen - colposcope - penis for curvature - male for sphincter tone, prostate, rectal and genital areas with scrotum and testicular abnormalities
43
how might you investigate dyspareunia?
- vaginal pH, microscopy - testing for STD - transvaginal USS - evaluate endometriosis - tissue biopsy if malignancy suspected
44
how might you manage dyspareunia?
- treat causes - water-based lubricants - oestrogen creams, tablets, rings for menopause - oral contraceptives - surgical or anatomical changes - abx for infection - sexual therapy and CBT
45
what surgeries are done for incontinence?
- The tension free vaginal tape (TVT) sling involves placing a tape of mesh underneath the urethra - burch colposuspension - laparoscopic colposuspension
46
what anatomical features are important in the pelvic floor?
- puborectalis for faecal incontinence by creating anorectal angle - pre-rectal fibres form a U shaped sling around urethra and vagina -> stress incontinence - uterus is supported by cardinal/transverse ligaments and the uterosacral ligaments
47
what risk factors are considered in those with prolapse?
- those who have had children - not apparent until after menopause with atrophy and weakening supports of pelvic organs - rare in those of African descent - increasing age - multiparity, vaginal deliveries - obesity - spina bifida
48
what are some types of prolapses?
dislocation of urethra cystocele or cystourethrocele rectocele uterine prolapse enterocoele perineal body prolapse
49
what is a cystocoele?
hernia of the bladder trigone due to weakness of the vaginal and pubocervical fascia bladder base descends and a bladder pouch is formed which may contain residual urine increasing the risk of UTIs
50
what is a rectocele?
prolapse of the posterior vaginal wall due to weakness or divarication of the levatores ani, the rectum bulges into the vagina
51
what is a uterine prolapse?
*descent of uterus and cervix - first degree: descent of the uterus, but cervix remains in the upper vagina - second: uterine descent when the cervix reaches down to the vulva on straining, but does not pass through it - third: when the cervix and some of or the entire uterus are prolapsed outside the vaginal orifice
52
what is an enterocoele?
pouch of Douglas hernia prolapse of the upper part of the posterior vaginal wall *Contains the peritoneum and usually a loop of bowel
53
what is a perineal body prolapse?
part of the anal canal may bulge into the vagina It follows inadequately sutured tears after childbirth or by failure of healing in such tears
54
what is dislocation of urethra?
urethra is displaced downwards and backwards off the pubis; may also become dilated (urethrocoele) This is caused by damage or weakness of the triangular ligament
55
how might a prolapse present?
- sensation of pressure, heaviness, 'bearing-down' - urinary symptoms: incontinence, frequency, urgency
56
how is prolapse managed?
- physio: effective in young women - pessary tx: temporary - surgery - cystocele/cystourethrocele: anterior colporrhaphy, colposuspension - uterine prolapse: hysterectomy, sacrohysteropexy - rectocele: posterior colporrhaphy
57
what are the indications for a pessary tx?
- Prolapse during pregnancy - Prolapse immediately after delivery - When another pregnancy is desired within a short period of time - Patients unfit for surgery on medical grounds - Patients who decline an operation
58
what are some disadvantages for pessary?
- Ulceration of the vagina or cervix – reduced by changing the pessary every 6 months and regularly using oestrogen creams - A neglected pessary may become embedded in the vaginal wall - Carcinoma of the vagina may develop
59
when might surgery be offered in prolapse?
Should only be performed if there is no evidence of genuine stress incontinence, significant detrusor instability, or any urinary symptoms – if there is detrusor instability may make it worse and cause urinary retention
