UPDATE IN UROGYNAECOLOGY
  • Bernard T. Haylen

2
UROGYNAECOLOGY
  • AREA OF GYNAECOLOGY AND FEMALE
  • UROLOGY INVOLVING THE ASSESSMENT
  • AND TREATMENT OF LOWER URINARY
  • TRACT AND PELVIC FLOOR DYSFUNCTION
  • INCLUDING UTERINE AND VAGINAL
  • PROLAPSE

3
INCIDENCE OF UROGYNAECOLOGICAL PROBLEMS
  • OVERALL
  • High
  • INCONTINENCE
  • 34 Australian women (11 severe)
  • PROLAPSE
  • 50 of postmenopausal women at routine
    gynaecological examination will have some degree
    of prolapse

4
UROGYNAECOLOGY
  • DIAGNOSES

5
UROGYNAECOLOGY - COMMON DIAGNOSES
  • URODYNAMIC STRESS INCONTINENCE
  • (USI) - 70
  • DETRUSOR OVERACTIVITY (DO) 15-40
  • VOIDING DIFFICULTIES 14-39
  • (Definition dependent)
  • UTERINE/VAGINAL PROLAPSE - 65

6
UROGYNAECOLOGY - URODYNAMIC STRESS INCONTINENCE
(USI)
  • The diagnosis of USI is urinary incontinence due
    to weakness or incompetence of the bladder neck
    and/or urethral sphincter closure mechanisms that
    normally maintain continence
  • The symptom of stress incontinence is the
    involuntary loss of urine with coughing,
    sneezing, running, jumping etc. This is the most
    likely associated symptom of USI.

7
UROGYNAECOLOGY - DETRUSOR OVERACTIVITY (DO)
  • Abnormal contractions of the intrinsic bladder
    (detrusor) musculature
  • Irritable bladder symptoms such as frequency,
    urgency, urge incontinence and nocturnal enuresis
    are more likely to be present with this condition

8
UROGYNAECOLOGY VOIDING DIFFICULTY
  • Abnormally slow or incomplete micturition
  • Abnormally slow urine flow rate or high postvoid
    residual urine volume
  • If high residual (over 30mls) recurrent urinary
    tract infections can ensue
  • May be due to hypotonic or atonic bladder or
    bladder outflow obstruction

9
UROGYNAECOLOGY - UTERINE/VAGINAL PROLAPSE
  • Abnormal descent into the vagina of the uterus,
    bladder (cystocoele) vaginal vault (enterocoele)
    or rectum (rectocoele)
  • 560 Consecutive urogynaecology patients with
    incidence of
  • . Uterine prolapse (15 overall)
  • . Cystocoele (57
    overall)
  • . Rectocoele (41
    overall)
  • . Enterocoele ( 8
    overall)

10
UROGYNAECOLOGY - OTHER DIAGNOSES
  • MIXED DIAGNOSES
  • Its very common for women to have more than
    one of the most common diagnoses e.g USI/DO,
    USI/prolapse
  • Women with prolapse often have USI and may
    also have DO and voiding difficulties
  • INTERCURRENT DIAGNOSES
  • 8 of urogynaecology patients will have other
    pelvic pathology (e.g. fibroids, ovarian
    pathology) whilst many more will have other
    gynaecological symptomatology.
  • OTHER DIAGNOSES
  • . Inflammation, Fistula, Urethral Diverticulum

11
UROGYNAECOLOGY RECURRENT URINARY TRACT
INFECTIONS
  • One of the most common bacterial infections in
    General Practice.
  • 40 women affected sometime in their life
  • 27 have a recurrence within 6 to 12 months
  • Definition uncertain to date
  • 2 or more symptomatic and medically
    documented UTI in the last 12 months

12
UROGYNAECOLOGY RECURRENT URINARY TRACT
INFECTIONS
  • 1140 consecutive first visit referrals for
    urogynaecological assessment
  • Full history, examination, urodynamics
  • Prevalence 18.6
  • Main Risk factors
  • Nulliparity 3.7x (18-50yrs) 1.8x (over 50)
  • Postvoid Residual (PVR) over 30mls

13
UROGYNAECOLOGY
  • AETIOLOGY
  • (for background reading)

14
UROGYNAECOLOGY AETIOLOGY OF URODYNAMIC STRESS
INCONTINENCE
  • 1 CHILDBIRTH Number 1 cause by far
  • Risk Factors Vaginal delivery heavy baby
    (gt4kg) prolonged 2nd stage labour (gt1hr
    pushing). Caesarean section protective in short
    term.
  • 2 MENOPAUSE Mean age for presentation of women
    with urinary tract and pelvic floor dysfunction
    is 55 years.
  • 3 HYSTERECTOMY Much incontinence present but
    not discussed at time of hysterectomy. Some new
    dysfunction post-hysterectomy with voiding
    difficulties not uncommon.

15
UROGYNAECOLOGY AETIOLOGY OF DETRUSOR
OVERACTIVITY
  • MANY THEORIES
  • 1 IDIOPATHIC Absence of inhibitory
    neuro-transmitters or increased spontaneous
    detrusor contractions
  • 2 NEUROGENIC Lesions to frontal lobe, pontine
    lesions or lesions above S2-4 give detrusor
    overactivity
  • 3 OBSTRUCTIVE Postsurgical or with prolapse
  • 4 INFECTIVE

16
UROGYNAECOLOGY AETIOLOGY OF PROLAPSE
  • 1 CHILDBIRTH
  • 2 HYSTERECTOMY
  • 3 MENOPAUSE
  • 4 PREVIOUS PROLAPSE / INCONTINENCE SURGERY

17
UROGYNAECOLOGY AETIOLOGY OF VOIDING DIFFICULTY
  • 1 BLADDER OUTFLOW OBSTRUCTION
  • Idiopathic . Drugs (e.g
    tricyclics)
  • Postoperative . Obstructive effect
    of prolapse
  • Psychogenic . Distal urethral
    (ageing) changes
  • Infective . External
    pressure (retroversion)
  • 2 HYPOTONIC / ATONIC BLADDER
  • Postpartum retention
  • LMN Lesion (diabetes, peripheral neuropathy)
  • Overdistension

18
UROGYNAECOLOGY
  • ASSESSMENT

19
UROGYNAECOLOGY - INITIAL ASSESSMENT - (ALL
PRACTITIONERS)
  • 1 HISTORY
  • Full history with symptoms of incontinence,
    bladder irritability, prolapse and voiding
    difficulty sought
  • 2 EXAMINATION
  • General, Clinical Stress Leakage, Sims Speculum
    (prolapse), Bimanual
  • 3 MSU
  • 4 BLADDER CHART
  • 5 POSTVOID RESIDUAL (U/S)/ RENAL TRACT U/S if
    recurrent UTI

20
UROGYNAECOLOGY - COMMON SYMPTOMS
  • 1 INCONTINENCE
  • Stress, Urge, Coital, Nocturnal
  • 2 IRRITATIVE
  • Urgency, Frequency (gt 7), Nocturia (gt1)
  • 3 VOIDING
  • Hesitancy, Poor stream, Sense of incomplete
    emptying, Need to immediately revoid, Strain to
    void
  • 4 PROLAPSE
  • Pelvic pressure, Vaginal lump, Sacral backache,
  • Dyspareunia.
  • 5 OTHER
  • Gynaecological (pelvic pain, menstrual
    dysfunction), Neurological, Diabetes

21
UROGYNAECOLOGY - ROLE OF SYMPTOMS
  • MOST WOMEN WITH PELVIC FLOOR
  • DYSFUNCTION WILL PRESENT WITH
  • MULTIPLE SYMPTOMS SUGGESTIVE OF
  • MORE THAN ONE UROGYNAECOLOGICAL
  • DIAGNOSIS.

22
UROGYNAECOLOGY COMMON SIGNS
  • A CLINICAL STRESS LEAKAGE
  • . Bladder FULL, Standing or left lateral
    position
  • . Occult stress prolapse reduced to see
    leakage
  • B PROLAPSE (UTERINE/VAGINAL)
  • . Bladder EMPTY, Left lateral (Sims)
    position
  • C INTERCURRENT GYNAE/UROLOGY PATHOLOGY
  • . Bimanual pelvic examination
  • . Speculum examination
  • . Vulval examination
  • . Vaginal ultrasound examination ( generally
  • specialist assessment)

23
FEMALE URINARY INCONTINENCE CLINICAL EXAMINATION
  • GRADING OF PELVIC ORGAN PROLAPSE (POP) - ICS
  • For each of uterine prolapse, cystocoele,
    rectocoele, enterocoele
  • GRADE 0 No prolapse
  • GRADE 1 Descent towards vaginal introitus (gt1cm
    above hymen)
  • GRADE 2 Descent to vaginal introitus (hymen /-
    1cm from hymen)
  • GRADE 3 Descent through introitus (gt 1cm below
    hymen)
  • GRADE 4 Prolapse totally outside introitus
  • (uterine grade 4
    procidentia)

26
UROGYNAECOLOGY ROLE OF MID STREAM URINE
  • 33 of women with symptoms of pelvic floor
    dysfunction will have frequency and/or dysuria -
    ? UTI
  • UTI might cause or exacerbate symptoms of pelvic
    floor dysfunction
  •  Recurrent UTIs might be a reflection of a
    chronic abnormally high postvoid residual (above
    30mls can lead to recurrent UTIs)

27
UROGYNAECOLOGY ROLE OF BLADDER DIARY
  • 3 DAYS CHARTING TIME AND AMOUNT OF EACH VOID,
    FLUID INTAKE AND EPISODES OF INCONTINENCE
  • Indicator of urinary frequency or nocturia (
    this can be altered by bladder training)
  • Indicator of average voided volume (should be
    200-300mls)
  • Indicator of severity of incontinence (number of
    leaks)
  • Indicator of above average (gt2 litres) or below
    average (under 1 litre) fluid intake

28
Figure 2 Bladder Diary
This simple chart allows you to record the fluid
you drink and the urine you pass over 3 days (not
necessarily consecutive) in the week prior to
your clinic appointment. This can provide
valuable information. Please fill in
approximately when and how much fluid you drink,
and the type of liquid. Please fill in the time
and the amount (in mls, or ounces) of urine
passed, and mark with a star if you have leaked
or mark with a P if you have needed to change
your pad. (Please find below an example of how to
complete this form.)

production / 24 hour 1250 ml Maximum voided
volume 300 ml Average void 125 ml
Position Section 2F (i/ii)
29
UROGYNAECOLOGY INITIAL GENERAL MEASURES
  • WEIGHT LOSS often reduces symptom of stress
    incontinence
  • REDUCED CAFFEINE reduced frequency, bladder
    irritability
  • IMPROVE CHEST CONDITIONS or other exacerbating
    factors for stress incontinence
  • VAGINAL OESTROGENS May improve frequency,
    nocturia, urgency and condition of the vaginal
    mucosa. Little proven benefit for incontinence
    over placebo
  • MEDICATIONS Adverse effect of diuretics,
    Minipress
  • PHYSIOTHERAPY Best if incontinence is mild to
    moderate and stress incontinence is the main
    symptom
