Pelvic organ prolapse

  1. 1. PELVIC ORGAN PROLAPSE DR. Okechukwu A. Ugwu
  3. 3. DEFINITION • Descent of one or more of the genital organs below their normal anatomical position. • Prolapse is a condition in which organs, which are normally supported by the pelvic floor, namely the bladder, bowel and uterus, herniate or protrude into the vagina due to weakness in their supporting structures.
  4. 4. Epidemiology • Common Problem in Women – 50% of parous women have some prolapse, 10-20% have symptoms • 11% Lifetime Risk for Surgery – Of these, 29% require repeat surgery • 5-7% Develop Post-Hysterectomy Vault Prolapse
  5. 5. ANATOMY-SUPPORTS OF THE UTERUS AND VAGINA The normal position of the uterus is maintained mainly by 3 factors: 1. The cervical ligaments: consist of 3 pairs: • The Mackenrodt’s/tranverse cervical/cardinal ligament; the most important part • The uterosacral ligaments • The Pubocervical ligaments 2. The pelvic floor muscles: The levator ani muscles is the most important & consists of 3 parts: – The ischio-coccygeus muscle – The ilio-coccygeus muscle – The pubo-coccygeus muscle; the most important part Others include obturator internus, coccygeus . 3. The anteverted position of the uterus/posterio Angulation of the vagina.

  10. 10. ANATOMY – posterior angulation of the vagina
  11. 11. Posterior Angulation of the vagina-2
  12. 12. Supports of the vagina Three Levels of Support: (DeLancey) • Level I (upper level): – Cardinal/Uterosacral ligaments • Level II (middle level): – Pubocervical fascia anteriorly – Rectovaginal fascia posteriorly – Levator ani muscles (through the arcus tendineus fasciae pelvis) • Level III (lower level): – Perineal membrane – Urogenital Diaphragm
  13. 13. RISK FACTORS • Increased intra-abdominal pressure. • Chronic cough. • Chronic constipation. • Weight lifting. • Presence of abdominal tumors e.g fibroid & ovarian cysts. • High impact exercises • Age/Menopause • Obesity • Smoking • Multiparity • Congenital Weakness-rare, due to deficiency in collagen metabolism • Injury to pelvic floor muscles • Iatrogenic/Pelvic surgery- Hysterectomy
  14. 14. AETIOPATHOGENESIS 1-Congenital weakness of the pelvic supports is associated with- short vagina, spina bifida & deep utero-vaginal & utero-sacral pouches It leads to the appearance of prolapse at an early age, the so-called “nulliparous” or even “virginal” prolapse. 2-Acquired weakness of pelvic supports; • This is assoc with direct injury to pelvic musculature and fasciae as well as partial denervation of pelvic floor muscles
  15. 15. AETIOPATHOGENESIS-contd Acquired weakness of the cervical ligaments and pelvic connective tissue A) Obstetric childbirth trauma: • Straining during the first stage of labour. • Wrong forceps application before full cervical dilatation. • Prolongation of the 2nd stage of labour leads to pressure & stretching of levator ani • Rapid succession of pregnancies; before involution of the pelvic structures. • unsutured or badly repaired perineal tear B) Postmenopausal atrophy: • Oestrogen deficiency & ageing may lead to loss of collagen and weakness in CT & fascia, particularly in patients predisposed to by obstetric trauma.

  18. 18. CLASSIFICATION OF PELVIC ORGAN PROLAPSE 1. Uterine prolapse: 1st, 2nd, or 3rd, degree 2. Vaginal prolapse: which may be; A) Anterior vaginal wall prolapse – Cystocele (bladder descent) – Urethrocele (urethral descent) – Cystourethrocele (both bladder and urethral descent) B) Posterior vaginal wall prolapse – Rectocele (rectal descent) – Enterocele (small bowel descent through the Pouch of Douglas) 3.

  32. 32. CLINICAL FEATURES OF PROLAPSE Symptomatic or asymptomatic: Exaggerated by effort and straining, and disappear by lying down & reduction 1. Sensation of pelvic heaviness 2. Backache; especially in uterine prolapse, due to stretch on uterosacral ligaments 3. A mass filling the vagina or protruding from the vulva; on straining or squatting, and disappears by lying down on the back. 4. Urinary symptoms: – Frequency of micturition by day due to mechanical irritation of the trigone. – Stress (urodynamic) Incontinence. – Inability to complete the act of micturition unless the anterior vaginal wall is pushed upwards and supported by the finger.- – Features of UTI – Acute urinary retention mostly in 1st trimester 5 .Bowel symptoms; heaviness in the rectum and a constant desire to defecate. 6. Decubitus ulcer. 8. Vaginal discharge 9. Dyspareunia 10. others- cough
  33. 33. DIFFERENTIAL DIAGNOSIS OF PROLAPSE • VAGINAL CYST • CERVICAL POLYP • ELONGATION OF THE CERVIX • Tumors of the urethra/Bladder • Large urethral Diverticulum • Skene’s and Bartholin’s gland cysts/abscess
  34. 34. MANAGEMENT • History- (age, risk factors and complications) • Physical examination- • Examine in either the Sims position[left lateral] or dorsal position- • Use a speculum to depress post vaginal wall to view anterior wall and vice versa. • Urinary stress incontinence also tested for. • Rectal examination to differentiate between rectocele and enterocele. • Rectovaginal examination • She can stand/squart and then cough/strain
  35. 35. Investigations in a case of prolapse 1. Urine analysis, microscopy, culture and sensitivity in cases with urinary symptoms. 2. Urodynamic studies in cases associated with stress incontinence. 3. IVU and cystography to delineate course of ureters and detect vesical pouch 4. Pelvic and abdominal US if suspected pelvic or pelviabdominal swellings. 5. Routine preoperative Investigations; blood chemistry, CBC, kidney and liver function tests. 6. Wound swab mcs 7. Others depend on history and finding- CXR in elderly,
  36. 36. TREATMENT OF PROLAPSE • The choice of treatment for genital prolapse depends on several factors including 1. The type and degree of prolapse 2. Her desire to preserve coital function. 3. Her desire to preserve fertility. 4. The patient’s acceptance for surgical treatment. 5. Her level of fitness for a surgical approach. Treatment options is divided into a)Conservative b)Surgical
  37. 37. CONSERVATIVE METHOD OF TREATMENT • While treating underlying conditions • Life style modification • Pelvic floor physiotherapy • Estrogen replacement therapy • Vaginal pessary
  38. 38. Pessary treatment of prolapse • Indications of pessary treatment 1. Temporary measure to allow for treatment of underlying conditions e.g.Promote healing of decubital ulcers prior to surgery 2. Patients who refuse surgery 3. During pregnancy 4. Medically unfit patients, as very old age, morbid obesity, cerebrovascular accidents, etc. 5. Therapeutic test to confirm that presenting symptoms are due to prolapse
  39. 39. Different types of pessaries
  40. 40. CARE OF PESSARY • The patient should be shown how to withdraw the pessary if it becomes displaced. • Inform her not to use contraceptive diaphragm while vaginal pessary is in place • Tell her to report any discomfort – (bleeding, disturbance in defecation or urinary function) immediately. • The patient should be examined 1-2weeks after insertion, a repeat exam can be done in 4 weeks after which visits should be 3-6month interval. • The pessary should be maintained with an acidic gel.
  41. 41. COMPLICATIONS OF PESSARIES • 1-Ulceration of vaginal vault. • 2-Impaction of pessary. • 3-Constipation. • 4-Stress incontinence when large type is used. • 5- Fistula • 6-Carcinoma of the vaginal wall in neglected cases. 7-Dyspareunia
  42. 42. OESTROGEN REPLACEMENT THERAPY • Important in postmenopausal women with atrophy of vaginal wall. • Mild degrees of prolapse may improve remarkably. • Oestrogen helps improve quality of vaginal mucosa and improves blood flow.
  43. 43. Surgical treatment for genital prolapse • Indications for Surgery a) Failed conservative treatment b)Severe degree of Prolapse c) Patient who has completed her family size and doesn't desire to preserve fertility • Surgical treatment is divided into: a) Conservative surgical methods b) Radical method c)Others- mgt of Vault prolapse
  44. 44. Conservative surgical methods • 1-Pelvic floor repair – Anterior colpo-perineorrhaphy. – Posterior colpo-perineorrhaphy. – Combination of ant & post types. 2-Manchester Fothergill operation. 3-Sacrohysteropexy and sacrospinous fixation 4-Vaginal colpocleisis – complete or incomplete. -Le Forts operation/complete-postmenopausal & surgically poor risk pxs.
  45. 45. Radical Surgery for Treatment of Prolapse Vaginal hysterectomy & pelvic floor repair: in older women when future pregnancy is not con- templated, or after menopause. It can be Abdominal, Vaginal or Laparoscopic Hysterectomy • Other surgical method include: Vaginal Vault Prolapse repair – Abdominal approach (abdominal sacro-colpopexy) – Vaginal approach (sacrospinous ligament fixation)
  46. 46. Complications of Surgical Treatment • Anaesthetic complication • Haemorrhage • Damage to surrounding structures • Wound breakdown • Recurrence • Vault Prolapse • Cervical stenosis/Incompetence • Preterm Labour • miscarriage = FROM CERVICALAMPUTATION • Cervical dystocia • Precipitate labour • Dyspareunia
  47. 47. Prevention of prolapse - Family planning/Child spacing to avoid repeated child birth - Proper selection of patients for instrumental delivery - Weight reduction/prevention of Obesity - Stop smoking - Partographic management of labour - good repair of episiotomy and perineal tears after labour - Avoid constipation in pueperium. -Encourage postnatal exercises

Notas do Editor

  • When the uterus prolapses, it carries the vagina along with it but the vaginal wall can prolapse without the uterus. Ie the vagina can prolapse independent of the uterus.
  • Pelvic muscles are in state of tonic contraction.
  • If vagina axis were to be vertical as in fig b, a slight increase in IAB will tend to cause vagina eversion.
  • NB; Essence of the level support: Level one support results in vaginal vault or uterine prolapse, level 11 support failure results in development of cystocoele/ rectocoele while level 111 support failure results in prolapse of bladder neck.
  • Overstretching and subsequent damage to the ligaments following attempt to bear down in first stage of labour.
  • It can be symptomatic or asymptomatic, most symptoms are posture dependent, Exaggerated by effort and straining, and disappear by lying down & reduction .
  • Life style modification may include advice on diet, weight loss in obese patients, increase fiber content in food, laxatives and modification of drug regimen including laxatives.
  • A) The Ring pessary: , The shelf pessary: , cup and stem” pessary: , determination of appropriate size is based on trial and error, optimal time interval for changing of pessary has also not been defined., careful examination at every 6 months is advisable and topical estrogen may reduce ulceration.
  • This anterior wall repair and plication of pubocervical fasciae was described by kelly in 1913 and it has become the treatment of choice.
