1 排尿障礙治療中心 版權所有 Pelvic Floor Anatomy and Female Lower Urinary Tract Dysfunction Hann-Chorng Kuo Department of Urology Buddhist Tzu Chi General Hospital

2 排尿障礙治療中心 版權所有 Abdomino-pelvic cavity Respiratory diaphragm Vertebral column Abdominal muscles Pelvic floor Intra-abdominal pressure Visceral weight & Gravity in erect body Maintain visceral function

3 排尿障礙治療中心 版權所有 Genital Support Pelvic floor- Pelvic visceral attachment to pelvic walls through endopelvic fascia Levator ani muscles- a pelvic diaphragm with a cleft in anterior portion Urogenital diaphragm connects perineal body to ischiopubic rami Bulocavernous, ischiocavernous, sup.transverse perineal, anal sphincter m.

11 排尿障礙治療中心 版權所有 The Urogenital Diaphragm

12 排尿障礙治療中心 版權所有 Female Perineum

13 排尿障礙治療中心 版權所有 The Function of Pelvic Floor Support pelvic and abdominal organs during stress of increased abdominal pressure Allow for opening of the pelvic floor to accommodate excretory functions and parturition Endopelvic fascia and visceral ligaments contains smooth muscles

14 排尿障礙治療中心 版權所有 The Pelvic Floor Attachments Pelvic floor support depends on its connection to the pelvic bones An evolutionary solution for support of visceral organs Pelvic floor muscles oppose gravity and increased abdominal pressures

15 排尿障礙治療中心 版權所有 Prevention of Prolapse Constriction – levator ani muscles constrict lumen of vagina Suspension – cardinal ligaments & uterosacral ligaments, pubocervical fascia act to suspend cervix and vagina Flap valve mechanism- anterior traction of levator ani m. and suspension of vagina in posterior pelvis

16 排尿障礙治療中心 版權所有 Prevention of Prolapse

17 排尿障礙治療中心 版權所有 Attachments of Pelvic Floor Tendinous arch of pelvic fascia- pubocervical fascia arises Tendinous arch of levator ani- levator ani muscles arise Pubourethral ligaments Pubovesical ligaments

18 排尿障礙治療中心 版權所有 Attachments of Pelvic Floor

19 排尿障礙治療中心 版權所有 Pelvic Floor Dysfunction A variety of fascial and anatomic defects Cystocele, rectocele, uterine prolapse, enterocele, vault prolapse Adequate diagnosis and staging of pelvic floor dysfunction is essential

20 排尿障礙治療中心 版權所有 Diagnosis of Pelvic Floor Dysfunction Detailed physical examination Pelvic ultrasound Fluoroscopy of rectum & bladder Magnetic resonance imaging (MRI)

21 排尿障礙治療中心 版權所有 Image Study of Pelvic Floor

22 排尿障礙治療中心 版權所有 The Urethropelvic Ligaments Bladder Smooth muscle Striated Symphysis pubis Striated muscle Smooth muscle Urethropelvic ligament Smooth muscle

23 排尿障礙治療中心 版權所有 Descent of Bladder during Stress

24 排尿障礙治療中心 版權所有 Cystocele Most Gr 1 and 2 cystoceles are asymptomatic High grade cystoceles are associated with vaginal buldging, vaginal pressure, dyspareunia, UTI, obstructive voiding, urinary retention A high grade cystocele may mask urethral hypermobility and stress incontinence

25 排尿障礙治療中心 版權所有 Physical examination of Cystocele

26 排尿障礙治療中心 版權所有 MRI of Cystocele

27 排尿障礙治療中心 版權所有 Enterocele Simple enterocele Complex enterocele- associated with vault prolapse and anterior or posterior vaginal prolapse Cause vaginal pressure, dyspareunia, low back pain, constipation, symptoms of bowel obstruction

28 排尿障礙治療中心 版權所有 Physical examination of Vaginal Cuff Prolapse

29 排尿障礙治療中心 版權所有 MRI of Enterocele

30 排尿障礙治療中心 版權所有 Rectocele Defect of prerectal and pararectal fascia,and rectovaginal septum Present in 80% asymptomatic patients Vaginal mass,vaginal pressure, dyspareunia,constipation

31 排尿障礙治療中心 版權所有 Physical examination of Rectocele

32 排尿障礙治療中心 版權所有 MRI of Rectocele

33 排尿障礙治療中心 版權所有 Uterine Prolapse Laxity of uterosacral ligaments May present with vaginal mass, dyspareunia, urinary retention, back pain Grade 4 prolapse is associated with ureteral obstruction

34 排尿障礙治療中心 版權所有 Physical examination of Uterine Prolapse

35 排尿障礙治療中心 版權所有 MRI of Uetrine Prolapse

36 排尿障礙治療中心 版權所有 Complete Eversion of Vaginal Vault

37 排尿障礙治療中心 版權所有 The Continence Mechanism

38 排尿障礙治療中心 版權所有 The Urethral Sphincter and Pelvic Floor

39 排尿障礙治療中心 版權所有 The External Urethral Sphincter

40 排尿障礙治療中心 版權所有 Pelvic Floor Relaxation Associated with damage to pubococcygeus muscle The muscle is lax, atrophied, poor tone Urinary stress incontinence Genital prolapse Sexual Problem Rectal stasis

41 排尿障礙治療中心 版權所有 Muscular Component of Pubococcygeus muscle Large diameter slow twitch type I fibers predominant- provide static visceral support Fast twitch type II fibers- assists in active closure of pelvic visceral organs 40% of women have lost function or coordination of this muscle

42 排尿障礙治療中心 版權所有 The Structures supporting Bladder and Urethra Arcus tendineus fascia pelvis Levator ani (pubococcygeus muscles) Pubovesical muscles or ligaments Vaginal muscle attachments to fascia and levator ani

43 排尿障礙治療中心 版權所有 The Structures supporting Bladder and Urethra

44 排尿障礙治療中心 版權所有 The Structures supporting Bladder and Urethra

45 排尿障礙治療中心 版權所有 The Hammock Theory of Extrinsic Continence Mechanism

48 排尿障礙治療中心 版權所有 Pelvic Floor Relaxation and Abdominal Leak Point Pressure

49 排尿障礙治療中心 版權所有 Pelvic Floor Relaxation Low LPP without Hypermobility

50 排尿障礙治療中心 版權所有 Pelvic Floor Relaxation High LPP with hypermobility

51 排尿障礙治療中心 版權所有 Pelvic Floor Relaxation CLPP > VLPP, mild hypermobility

52 排尿障礙治療中心 版權所有 Physical examination of Pelvic Floor Dysfunction General examination- cancer screen, stool OB, urinalysis, physical examination Neurological examination- paresthesia of dermatome, bulbocavernous reflex, voluntary contraction of anal sphincter Pelvic examination- cystocele, rectocele,uterine prolapse, vault prolapse Urinary incontinence by Valsalva maneuver or coughing

53 排尿障礙治療中心 版權所有 Staging of Pelvic Organ Prolapse Stage 0 - no prolapse Stage I - the most distal portion is >1cm above level of hymen Stage II - The most distal portion is <1cm proximal or distal to plane of hymen Stage III - The most distal portion is >1cm below plane of hymen, but < total vaginal length - 2 cm Stage IV - complete eversion of total length of lower genital tract, the distal portion is > TVL-2 cm, i.e. cervix or vaginal cuff

54 排尿障礙治療中心 版權所有 Evaluation of Pelvic Floor Muscle Function Assessing patient ’ s ability to contract and relax pelvic muscles separately Measuring the force of contraction Palpation of thickness of pelvic floor musculatures Electromyography Pressure recording

55 排尿障礙治療中心 版權所有 Measurement of Bladder Base Descent (The Q-tip Test)

56 排尿障礙治療中心 版權所有 Lower Urinary Tract Symptoms caused by Pelvic Organ Prolapse Stress incontinence Frequency, urgency, urge incontinence Hesitancy, weak stream, incomplete empty Manual reduction of prolapse for voiding Positional change to start or complete voiding

57 排尿障礙治療中心 版權所有 Bowel Symptoms caused by Pelvic Organ Prolapse Difficulty with defecation Incontinence of flatus Incontinence of liquid stool Incontinence of solid stool Fecal staining of underwear Digital manipulation to complete defecation Feeling of incomplete evacuation Rectal protrusion during or after defecation
