40%

32
Q

What is the most common type of GU prolapse?

A

Anterior vaginal wall prolapse

33
Q

Describe the pathophysiology of GU prolapse.

A

Pelvic floor organs are supported by levator ani muscle and endopelvic fascia.
When these structures are weakened e.g. by childbirth, one or more of the pelvic organs descends and can affect the vaginal wall.

34
Q

Where can GU prolapse occur?

A

Anterior, middle, or posterior compartment of the vagina.

35
Q

What are the 2 types of anterior GU prolapse? What are they?

A

Urethrocele - prolapse of the urethra.

Cystocele - prolapse of the bladder.

36
Q

What are the 3 types of middle GU prolapse? What are they?

A

Uterine prolapse - what it says on the tin.
Vaginal vault prolapse - again, read the tin.
Enterocele - herniation of pouch of douglas into vagina. Inc. small bowel or omentum.

37
Q

What is the posterior GU prolapse? What is?

A

Rectocele - prolapse of rectum into vagina

38
Q

How are GU prolpases classified?

A

By type and position of the most distal portion of the prolapse during straining.

39
Q

What system is used to classify prolapses?

A

POP-Q system

40
Q

What are the prolapse stages according to the POP-Q method of classification?

A 
Stage 0 - no prolapse
Stage 1 - more than 1cm above hymen
Stage 2 - within +-1cm to plane of hymen
Stage 3 - more than 1cm below plan of hymen, no further than 2cm less than total length of vagina
Stage 4 - complete eversion of vagina
41
Q

What are the risk factors for GU prolapse?

A
  • Increasing age
  • Vaginal delivery
  • Increasing parity
  • Obesity
  • Previous hysterectomy
42
Q

A 65 year old woman comes to see her GP with a feeling of “something coming down, down below”. What other symptoms might she be experiencing?

A
  • Sensation of pressure/fullness
  • Feel a bulge/protrusion
  • See or feel a protrusion
  • Spotting
  • Urinary symptoms
  • Coital difficulty
  • Bowel symptoms inc. needing to apply digital pressure to perienum to enable defecation
43
Q

How should a pt with suspected GU prolpase be examined?

A

Offer a chaperone!
Examine 1st while standing in left lateral position if possible, while straining. Both standing and supine.

Speculum - strain, look for degree of descent while removing speculum.

Check for ulceration and hypertrophy of cervix and vaginal mucosa if report bleeding or stage 2+ prolapse seen.

44
Q

How is diagnosis of GU prolpase made?

A

Clinically based on hx and ex.

45
Q

How can GU prolpase be investiagted, and when is this appropriate?

A

If urinary symptoms - urinalysis and MSU, Ix for incontinence, U and Es, renal ultrasound - as appropriate.
Bowel symtpoms - USS.

46
Q

How should a mild/asymptomatic prolapse be managed?

A

Not necessary generally to manage an aymptomatic prolapse.

47
Q

What are the 3 Mx options for GU prolapse?

A

Conservative
Pessarys
Surgery

48
Q

What conservative Mx can we offer for GU prolapse?

A
  • Watchful waiting
  • Lifestyle modification - weight loss, minimise heavy lifting, prevent/treat constipation.
  • Pelvic floor muscle exercises
  • Vaginal oestrogen creams
49
Q

Why are vaginal pessaries useful?

A

Good alternative to surgery, and work well alongside pelvic floor exercises.
Can be for short term symptom relief or long term use.

50
Q

What should a pt be told about vaginal pessaries before consenting to have one?

A
  • May need repeated fittings
  • May affect sexual intercourse
  • Needs changing every 6 months
  • Some complications
51
Q

What are the complications associated with vaginal pessaries?

A
  • Bleeding
  • Discharge
  • Difficult to remove
  • Expelled
  • Fistula formation (rare)
  • Faecal impaction
  • Hydronephrosis
  • Infection/urosepsis
52
Q

When should a pt be referred for surgical Mx of a GU prolapse?

A
  • Conservative Rx fails
  • Voiding problems or obstructed defecation
  • Recurrence of prolapse after surgery
  • Ulceration
  • Irreducible prolapse
53
Q

What are the surgical options for bladder/urethral prolapse?

A

Anterior colporrhaphy (anterior vaginal wall repair)

Colposuspension

54
Q

What are the surgical options for uterine prolapse?

A

Hysterectomy
Sacrocolpoplexy (good if woman wants to keep uterus)
Sacrospinus fixation

55
Q

What are the surgical options for rectal prolapse?

A

Posterior colporrhaphy

56
Q

What are the complications associated with GU prolapse?

A 
General:
-Infection
-Ulceration
Urinary incontinence, chronic retention, recurrent UTIs.
Bowel dysfunction.
57
Q

What are recurrent UTIs generally considered to be?

A

UTI occuring twice in 6 months, or 3 times in a year. These should be proven episodes.

58
Q

Who is affected by UTIs?

A

Everyone, but women mostly.

1 in 2 lifetime risk of UTI in a woman, and risk increases with age.

59
Q

Which organism is usually responsible for a UTI?

A

E. coli

60
Q

Other than E. coli, which organisms cause UTIs (mostly)?

A

Staphylococcus saprophyticus

Proteus mirabilis

61
Q

What might predispose someone to having recurrent UTIs?

A 
Diabetes
Sexual intercourse
Atrophic urethritis/vaginitis
Abnormal urinary tract (congenital or iatrogenic e.g. catheter)
Incomplete bladder emptying
Contraception
Urinary tract surgery
Immune compromise
First UTI under age 15
Hx of recurrent UTIs in mother
62
Q

What are the symptoms of UTIs?

A 
Dysuria
Frequency
Urgency
Nocturia
Haematuria
Supra-pubic pain
63
Q

What are the signs of a UTI?

A

Suprepublic tenderness
Cloudy and/or foul smelling urine
Incontinence/confusion/anorexia/fever/shock in elderly

64
Q

Why is an MSU needed in Ix of recurrent UTIs?

A

Because resistant organisms are more likely so they need to be cultured to see which abx work best.

65
Q

What would prompt you to refer a woman with recurrent UTIs to secondary care?

A

Underlying high risk factors for UTI
Cultures show multiresistant organisms
Pneumaturia/faecaluria/haematuria

66
Q

How can we detect structural abnormalities causing recurrent UTIs?

A

CT scan, but can also use ultrasound as an alternative

67
Q

How does antibiotic therapy differ in recurrent UTIs with underlying athology?

A

Treat for 5-10 days insetaed of 3-5.

Consider anticipatory prescribing for future episodes.

68
Q

What does prophylaxis for recurrent UTIs depend on?

A

If it is related to sexual intercourse or not.

If it isn’t, 6/12 course of low-dose nitrofurantoin/trimethoprim.

If it is, change contraceptive measure, suggest use of lubricant, offer 100mg trimethoprim to be taken within 2 hours of sexual intercourse.
