Genital prolapse - supports of uterus, degrees/types, clinical assessment, pessary and operative management.
Pelvic inflammatory disease (PID) - etiology, clinical diagnosis, complications, antibiotic regimens, prevention.
Ectopic pregnancy - risk factors, diagnosis including beta-hCG/TVS, expectant, medical and surgical management.
Carcinoma cervix - screening, FIGO staging, clinical features, investigations, treatment by stage, prevention.

Obstetrics

Mechanism of normal labour - cardinal movements, fetal head diameters, mechanism in occipitoanterior position.
Twin pregnancy - diagnosis, chorionicity, antenatal surveillance, complications, delivery planning.

Mechanism of normal labour

The mechanism of labour is the series of positional changes made by the fetus to pass through the maternal birth canal. It is described for a singleton, term fetus in longitudinal lie, vertex presentation, with a well-flexed head, usually beginning in an occipito-transverse position and ending in an occipitoanterior (OA) position.

The basic principle is:

The fetal head adapts its smallest possible diameters to the most favourable diameters of the maternal pelvis.

Cardinal movements

Engagement → Descent → Flexion → Internal rotation → Extension → Restitution → External rotation → Expulsion

A useful exam mnemonic is: “Every Daring Fellow In Egypt Rides Elephants Easily.”

Prerequisites for normal mechanism

Adequate uterine contractions
Normal maternal bony pelvis and soft tissues
Fetus of average size
Vertex presentation with good flexion
The fetal head and shoulders must adapt to the changing shape of the pelvic inlet, cavity, and outlet.

Important diameters

Structure	Important diameter
Engaging transverse diameter of fetal head	Biparietal diameter: 9.5 cm
Diameter of a well-flexed vertex	Suboccipitobregmatic: 9.5 cm
AP diameter of outlet	Approximately 11.5 cm
Transverse diameter of outlet, intertuberous	Approximately 11 cm

Mechanism in left occipitoanterior presentation

In an LOA position, the occiput initially lies toward the mother's left anterior pelvic quadrant. The head usually enters the pelvic inlet in an oblique or transverse diameter.

1. Engagement

Definition: Engagement occurs when the widest transverse diameter of the fetal head, the biparietal diameter, has passed through the plane of the pelvic inlet.

Clinically, it corresponds approximately to the presenting part at the level of the ischial spines, station 0.
In primigravidae, engagement often occurs before labour or early in labour.
In multiparae, it may occur later, sometimes during labour.

      └───────────┘
            ↓
         Symphysis pubis

Important point: With a well-flexed head, the engaging AP diameter is the suboccipitobregmatic diameter (9.5 cm).

2. Descent

Descent is the downward movement of the presenting part through the pelvis.

It begins with engagement and continues throughout labour, becoming most marked during the second stage.

Forces responsible

Uterine contractions
Maternal bearing-down efforts in the second stage
Straightening of the fetal body
Extension of the fetal trunk after delivery of the shoulders

          +3  |  Head visible at introitus
              |
         Pelvic outlet

3. Flexion

As the head meets resistance from the cervix, pelvic walls, and pelvic floor, the fetal chin moves toward the chest. This is flexion.

Why is flexion important?

Flexion substitutes a larger head diameter with a smaller one:

Deflexed head                Well-flexed head

Occipitofrontal              Suboccipitobregmatic
diameter: 11.5 cm            diameter: 9.5 cm
       ↓                            ↓
Less favourable              Most favourable

Thus, flexion permits the head to descend through the pelvis with the suboccipitobregmatic diameter presenting.

4. Internal rotation of the head

As the flexed head reaches the pelvic floor, it rotates so that the occiput moves anteriorly beneath the maternal symphysis pubis.

In LOA, the occiput generally rotates 45 degrees anteriorly to reach direct OA.
If the head began in left occipitotransverse, it rotates approximately 90 degrees anteriorly.
This occurs because the pelvic floor directs the presenting part forward.

      Symphysis pubis             Symphysis pubis

Result: The sagittal suture comes to lie in the AP diameter of the outlet and the occiput lies under the pubic arch.

5. Extension

After internal rotation, the occiput lies below the symphysis pubis. The pelvic floor resists further straight descent. The subpubic region acts as a fulcrum, so the head is delivered by extension.

The parts appear successively over the perineum:

Occiput
Bregma
Forehead
Face
Chin

                       chin
                     Perineum

At this stage, the head is born with the face directed posteriorly, toward the maternal anus.

Crowning

Crowning is present when the largest circumference of the fetal head is encircled by the vulval ring and the head no longer recedes between contractions.

6. Restitution

After the head is delivered, it rotates slightly, usually by about 45 degrees, to return to its original relationship with the fetal shoulders.

This movement is called restitution.

The head had rotated independently during internal rotation.
Restitution corrects this twist in the fetal neck.
In LOA, the head generally turns toward the maternal left thigh after delivery.

  Symphysis pubis            Turns toward fetal back

7. External rotation

The shoulders, which entered the inlet in an oblique diameter, now undergo internal rotation to lie in the AP diameter of the pelvic outlet.

The delivered head rotates externally at the same time. This visible movement is termed external rotation.

Fetal head descent and cardinal movements

Short exam answer

In a normal vertex labour, the fetal head engages with the biparietal diameter passing through the pelvic inlet. Descent occurs progressively under uterine contractions and maternal bearing-down efforts. Resistance causes flexion, allowing the suboccipitobregmatic diameter to present. At the pelvic floor, the occiput rotates anteriorly beneath the symphysis pubis. The head is then born by extension, followed by restitution and external rotation as the shoulders rotate into the AP diameter of the outlet. Finally, the anterior shoulder is born under the symphysis, followed by the posterior shoulder and the rest of the body.

The sequence and descriptions above are consistent with standard obstetric teaching. The accessible textbook figure depicts engagement of the flexed head, internal rotation to OA, extension, and external rotation: Pfenninger and Fowler's Procedures for Primary Care, p. 1217.

ACOG pelvic organ prolapse evaluation management practice guidance

I do not have access to your specific D.C. Dutta edition or Marrow OBG Notes, 8th edition, so I cannot reproduce or claim exact textbook wording. I can prepare an original, detailed, exam-oriented note aligned with standard OBG teaching and current POP guidance.

For genital prolapse, the full answer can be organized as:

Definition and terminology
Pelvic supports of uterus and vagina
Etiology and risk factors
Pathogenesis and types of prolapse
Cystocele, urethrocele, rectocele, enterocele, uterine prolapse, vault prolapse
Clinical features and complications
Clinical examination and grading, including POP-Q
Investigations
Conservative treatment and pessaries
Surgical management, with uterus-preserving versus hysterectomy-based procedures
Special situations: young women, women desiring fertility, elderly or medically unfit patients
Recurrence, prevention, and viva points

At a high level, pelvic organ prolapse results from failure of pelvic-floor muscles, endopelvic fascial supports, and apical suspensory ligaments. Management is symptom-directed and ranges from pelvic-floor training and pessaries to reconstructive or obliterative surgery. Current evidence also requires careful counselling about mesh, particularly because transvaginal mesh for prolapse has important safety concerns; see the ACOG POP guidance.

"Pelvic Organ Prolapse"[MeSH Terms] AND treatment

Genital Prolapse

Note: I do not have the text of the requested D.C. Dutta or Marrow OBG Notes edition available for verbatim reproduction. The following is an original, detailed examination note organized in the traditional D.C. Dutta style and cross-checked against standard urogynecology teaching. Pelvic organ prolapse definitions, compartmental approach, and POP-Q details are consistent with Berek & Novak's Gynecology, pp. 1592, 1610-1611.

1. Definition

Genital prolapse is the downward displacement of one or more pelvic organs, resulting from failure of their supporting structures, so that the uterus, vaginal walls, bladder, rectum, or small bowel bulges into or beyond the vaginal introitus.

Modern terminology calls this pelvic organ prolapse (POP). It includes descent of:

Anterior vaginal wall
Posterior vaginal wall
Uterus and cervix
Vaginal vault after hysterectomy

Clinically meaningful prolapse usually causes a vaginal bulge, pressure symptoms, urinary symptoms, bowel symptoms, sexual dysfunction, or ulceration.

2. Normal supports of uterus and vagina

Understanding the supports is essential for both theory questions and selecting surgery.

A. Primary supports

1. Pelvic diaphragm

The pelvic diaphragm is chiefly formed by the levator ani muscle, along with coccygeus muscle and their fascial coverings.

The levator ani consists of:

Puborectalis
Pubococcygeus
Iliococcygeus

Functions

Supports the pelvic viscera from below.
Maintains the levator hiatus.
Resists rise in intra-abdominal pressure during coughing, straining, lifting, and defecation.
Maintains the normal vaginal axis.
Keeps the upper vagina directed posteriorly toward the sacrum rather than downward toward the vaginal opening.

The puborectalis is particularly important. It forms a sling around the anorectal junction and contributes to the pelvic floor's supportive function.

2. Urogenital diaphragm and perineal membrane

These support the distal vagina and urethra.

They include:

Perineal membrane
Deep transverse perineal muscles
Sphincter urethrae complex
Associated fascia

They are more important for support of the lower anterior vaginal wall and urethrovesical junction.

3. Perineal body

The perineal body is a fibromuscular mass situated between the lower vagina and anus.

Muscles attached to it include:

Bulbospongiosus
Superficial transverse perineal muscles
External anal sphincter
Fibers of levator ani

It is an important support for the posterior vaginal wall. Damage during childbirth, especially with perineal tears, poorly repaired episiotomy, or instrumental delivery, weakens posterior support and predisposes to rectocele and perineal descent.

B. Ligamentous and fascial supports

1. Uterosacral ligaments

Extend from cervix and upper vagina backward to sacrum, usually around S2-S4.
They support the cervix and upper vagina posteriorly.
They are important for apical support.

2. Cardinal ligaments, also called transverse cervical or Mackenrodt ligaments

Extend from cervix and upper vagina laterally toward the pelvic sidewall.
Provide lateral support to cervix and upper vagina.
They contain uterine vessels.

The uterosacral-cardinal ligament complex is the main suspensory apparatus of the uterine cervix and vaginal apex.

3. Pubocervical fascia

Lies between bladder and anterior vaginal wall.
Supports bladder base and proximal urethra.
Defect or attenuation leads to anterior vaginal wall prolapse, especially cystocele.

4. Rectovaginal fascia

Lies between rectum and posterior vaginal wall.
Supports posterior vaginal wall.
Damage leads to rectocele.

5. Endopelvic fascia

This is a connective-tissue network that attaches pelvic viscera and vagina to the pelvic sidewall. Defects can be central, lateral, or apical.

C. Traditional classification of uterine supports

True supports

Pelvic diaphragm
Urogenital diaphragm
Perineal body
Uterosacral ligaments
Cardinal ligaments
Pubocervical and rectovaginal fascia

False supports

These maintain uterine position but are not the principal supports against prolapse:

Round ligaments
Broad ligaments
Uterovesical fold of peritoneum
Position of uterus, normally anteverted and anteflexed

3. Etiology and risk factors

Genital prolapse is usually multifactorial. It results from failure of muscular, fascial, neural, and ligamentous support.

A. Congenital and constitutional factors

Congenital weakness of connective tissue
Familial predisposition
Connective-tissue disorders, for example Ehlers-Danlos syndrome
Naturally wide pelvic outlet
Poorly developed pelvic floor
Spina bifida or neuropathic pelvic floor disorders

These may explain prolapse in nulliparous or young women.

B. Obstetric trauma

This is a major cause in multiparous women.

Risk factors include:

Multiple vaginal births
Prolonged second stage of labour
Obstructed labour
Large baby
Instrumental vaginal delivery
Malposition, especially persistent occipitoposterior position
Inadequately repaired perineal tear
Third- or fourth-degree perineal tear
Repeated childbirth at short intervals
Difficult or traumatic delivery

Mechanism of obstetric injury

During vaginal childbirth there may be:

Stretching or avulsion of levator ani muscles
Pudendal nerve injury
Stretching or tears in endopelvic fascia
Damage to perineal body
Injury to uterosacral-cardinal ligament support

The result can be widening of genital hiatus, loss of vaginal support, and descent of pelvic organs.

C. Increased intra-abdominal pressure

Chronic elevation of intra-abdominal pressure progressively stretches weakened supports.

Causes include:

Chronic cough, such as COPD, chronic bronchitis, asthma, smoking-related cough
Chronic constipation and habitual straining
Heavy manual work or repeated heavy lifting
Obesity
Ascites
Pelvic or abdominal mass

D. Menopause and aging

After menopause:

Estrogen deficiency causes vaginal atrophy.
Connective tissue becomes weaker.
Muscle mass and pelvic-floor tone decline.
Tissue healing capacity is reduced.

Therefore, prolapse becomes more frequent and may worsen with age.

E. Previous pelvic surgery

Hysterectomy without adequate vault suspension can lead to post-hysterectomy vaginal vault prolapse.
Previous prolapse surgery may fail or recur.
Radical pelvic surgery can damage nerve and fascial support.

4. Pathogenesis

Prolapse develops when the force pushing pelvic organs downward exceeds the resistance offered by pelvic-floor muscles, fascia, and ligamentous supports.

Key pathological events

Weakness or injury of levator ani widens the levator hiatus.
Vaginal walls become less firmly attached to the pelvic sidewalls.
Fascial supports stretch or tear.
Uterosacral-cardinal ligament complex fails.
Uterus or vaginal vault descends.
The vaginal axis becomes more vertical.
Repeated gravitational force and straining increase the prolapse.

Important concept

Prolapse of one compartment often coexists with defects in another compartment. For example:

Uterine prolapse may coexist with cystocele and rectocele.
Repairing only the visible anterior wall defect without correcting apical support may lead to recurrence.

5. Types of genital prolapse

Genital prolapse is classified anatomically into three compartments.

Compartment	Main structure involved	Common clinical name
Anterior	Bladder, urethra	Cystocele, urethrocele
Apical or middle	Uterus, cervix, vaginal vault, small bowel	Uterine prolapse, vault prolapse, enterocele
Posterior	Rectum, small bowel	Rectocele, enterocele

A. Anterior compartment prolapse

1. Cystocele

A cystocele is protrusion of the bladder into the anterior vaginal wall due to weakness of pubocervical fascia.

Features

Anterior vaginal wall bulge
Frequency of micturition
Urgency
Stress urinary incontinence
Difficulty in emptying bladder
Feeling of incomplete evacuation
Recurrent UTI
Need to reduce the bulge manually before voiding in advanced cases

Types of cystocele

Central defect: weakness of central pubocervical fascia.
Lateral defect or paravaginal defect: detachment of fascia from arcus tendineus fascia pelvis.
Apical cystocele: associated with loss of upper vaginal or apical support.

2. Urethrocele

A urethrocele is downward displacement of the urethra into the anterior vaginal wall.

It commonly accompanies cystocele, hence the term cystourethrocele.

B. Apical or middle compartment prolapse

1. Uterine prolapse

Downward descent of the uterus and cervix through the vagina due to failure of supports.

It is often associated with:

Cystocele
Rectocele
Enterocele
Elongation of cervix

2. Vaginal vault prolapse

This is descent of the vaginal apex after hysterectomy.

It occurs when the upper vagina is not adequately attached to the uterosacral-cardinal support complex at the time of hysterectomy.

3. Enterocele

An enterocele is herniation of the peritoneal sac, usually containing small bowel, into the upper posterior vaginal wall.

It may occur:

With uterine prolapse
After hysterectomy
As a posterior vaginal wall bulge
In association with vault prolapse

Symptoms may include pelvic heaviness, low backache, pressure, and bowel dysfunction.

C. Posterior compartment prolapse

Rectocele

A rectocele is protrusion of the anterior rectal wall into the posterior vaginal wall due to weakness of rectovaginal fascia and/or perineal body.

Symptoms

Difficulty in defecation
Sensation of incomplete evacuation
Need for repeated straining
Need to press the posterior vaginal wall or perineum to pass stool, called digital splinting
Constipation
Feeling of a posterior vaginal bulge

A rectocele should not automatically be assumed to be the cause of constipation. Functional defecatory disorders must also be considered.

6. Degrees of uterine prolapse

Traditional clinical grading is as follows.

First-degree uterine prolapse

Cervix descends into vagina but does not reach the introitus.
Usually mild.
May be asymptomatic or associated with pelvic heaviness and backache.

Second-degree uterine prolapse

Cervix descends to or through the vaginal introitus.
The uterus is partly within the vagina.
Usually associated with cystocele and rectocele.

Third-degree uterine prolapse, procidentia

Entire uterus lies outside the vaginal introitus.
Vaginal walls are everted.
Often associated with cystocele, rectocele, enterocele, and decubitus ulcer.

Complete procidentia

Complete prolapse of uterus along with eversion of the entire vagina outside the vulva.

7. Cervical elongation

Cervical elongation must be distinguished from true uterine prolapse.

A. Supravaginal elongation of cervix

Cervix is elongated.
Fundus may remain relatively high.
Uterosacral and cardinal supports may be relatively preserved.
Commonly associated with uterine prolapse.
Measured by a long cervical length relative to uterine corpus.

B. Infravaginal elongation

Elongation of ectocervix below vaginal attachment.
May be congenital or acquired.
Vaginal fornices remain at normal level.
May mimic prolapse.

This distinction affects surgical choice. Manchester operation is traditionally considered in selected women with cervical elongation and uterine conservation wishes.

8. Clinical features

A. Local symptoms

Feeling of something coming down per vaginam
Vaginal bulge or mass
Pelvic dragging sensation
Pelvic heaviness
Low backache
Symptoms increase with standing, exertion, coughing, and lifting
Symptoms improve on lying down
Vaginal discharge due to congestion or ulceration
Contact bleeding from decubitus ulcer
Difficulty walking in severe procidentia

B. Urinary symptoms

These are particularly common with anterior compartment prolapse.

Frequency
Urgency
Nocturia
Stress urinary incontinence
Urge urinary incontinence
Hesitancy
Poor urinary stream
Incomplete bladder emptying
Retention
Recurrent UTI
Overflow incontinence in severe obstruction

Occult stress urinary incontinence

A severe prolapse may kink the urethra and mask stress urinary incontinence. After reduction of prolapse, stress incontinence may become evident. This is called occult SUI.

C. Bowel symptoms

Constipation
Straining
Incomplete evacuation
Obstructed defecation
Digital splinting
Fecal urgency or incontinence in some patients

D. Sexual symptoms

Dyspareunia
Reduced sexual satisfaction
Vaginal dryness due to atrophy
Fear or embarrassment due to visible bulge

9. Complications

Local complications

Congestion and edema of prolapsed tissues
Keratinization of exposed vaginal epithelium
Excoriation
Infection
Decubitus ulcer
Bleeding
Offensive vaginal discharge
Rarely, malignant change must be excluded in a chronic nonhealing ulcer

Urinary complications

Recurrent urinary tract infection
Acute urinary retention
Chronic retention
Hydroureter
Hydronephrosis
Renal impairment in neglected severe cases

Bowel complications

Chronic constipation
Obstructed defecation
Fecal impaction

10. Clinical examination

A. General examination

Assess:

Age and parity
Nutritional state
BMI
Chronic cough
Signs of COPD
Abdominal mass or ascites
Previous scars
Mobility and fitness for surgery

B. Abdominal examination

Look for:

Mass
Ascites
Distended bladder
Previous abdominal scars
Hernia

C. Local examination

Examine with the woman in lithotomy position. Assessment may be repeated standing if the prolapse is not apparent.

Inspection

Ask the patient to cough or strain.

Look for:

Degree of uterine descent
Anterior vaginal wall prolapse
Posterior vaginal wall prolapse
Eversion of vaginal walls
Decubitus ulcer
Cervical elongation
Vaginal atrophy
Perineal body deficiency
Widened genital hiatus
Previous episiotomy scar
Urinary leakage on coughing

Speculum examination

A Sims speculum is useful.

Retract posterior vaginal wall to assess anterior prolapse.
Retract anterior wall to assess posterior prolapse.
Support apex when evaluating isolated wall defects.
Inspect cervix and vagina for ulceration, discharge, growth, and atrophy.

Bimanual examination

Assess:

Uterine size
Uterine mobility
Cervical length
Adnexal mass
Associated pelvic pathology

Rectovaginal examination

Useful to assess:

Rectocele
Enterocele
Integrity of rectovaginal septum
Perineal body
Anal sphincter tone
Rectal pathology

11. POP-Q classification

The Pelvic Organ Prolapse Quantification system, POP-Q, is the standardized contemporary method for recording prolapse.

The hymen is the fixed reference point:

Measurements above hymen are negative.
Measurements beyond hymen are positive.

POP-Q points

Point	Site
Aa	Fixed point on anterior wall, 3 cm proximal to urethral meatus
Ba	Most distal point of upper anterior vaginal wall
C	Cervix or vaginal cuff scar
D	Posterior fornix, used only when uterus is present
Ap	Fixed point on posterior wall, 3 cm proximal to hymen
Bp	Most distal point of upper posterior vaginal wall
gh	Genital hiatus
pb	Perineal body
tvl	Total vaginal length

POP-Q stages

Stage	Definition
Stage 0	No prolapse
Stage I	Leading edge remains more than 1 cm above hymen
Stage II	Leading edge lies between 1 cm above and 1 cm below hymen
Stage III	Leading edge is more than 1 cm below hymen but not complete eversion
Stage IV	Complete or near-complete vaginal eversion

POP-Q permits accurate documentation, comparison during follow-up, and communication between clinicians. Berek & Novak's Gynecology, pp. 1610-1611.

12. Investigations

Diagnosis is primarily clinical. Investigations are tailored to symptoms and planned surgery.

Basic investigations

Urinalysis
Urine culture if urinary symptoms
Complete blood count if ulcer bleeding or preoperative assessment
Blood glucose, renal function, and preoperative tests as required
Cervical cytology according to screening eligibility
Biopsy of suspicious, bleeding, indurated, or nonhealing ulcer

Bladder assessment

Postvoid residual urine
Cough stress test with prolapse reduced
Uroflowmetry in voiding difficulty
Urodynamic study in selected patients, especially if:
- Mixed urinary symptoms
- Voiding dysfunction
- Prior incontinence surgery
- Suspected occult SUI
- Unclear diagnosis

Imaging

Not routine for straightforward cases.

Possible indications:

Pelvic ultrasound for uterine or adnexal pathology
Renal ultrasound in severe procidentia or suspected urinary obstruction
MRI or defecography in complex posterior-compartment and defecatory disorders

13. Management principles

Treatment depends on:

Symptoms and their effect on quality of life
Compartment(s) involved
Severity of prolapse
Age
Desire for future fertility and preservation of uterus
Sexual activity
General health and anesthetic fitness
Associated urinary and bowel symptoms
Previous surgery
Surgeon expertise and patient preference

An asymptomatic prolapse does not necessarily require treatment.

A. Conservative treatment

1. Lifestyle modification

Correct factors that increase intra-abdominal pressure:

Weight reduction where appropriate
Treat chronic cough
Smoking cessation
Treat constipation
Avoid repeated heavy lifting
Optimize diabetes and general health

2. Pelvic floor muscle training

Appropriate for mild prolapse, especially stage I or II, and for women desiring conservative care.

It may:

Improve pelvic-floor strength
Reduce symptoms
Improve support
Help coexisting urinary incontinence

It is less likely to reverse advanced procidentia.

A supervised physiotherapy program is preferred.

3. Local vaginal estrogen

May be used in postmenopausal women with vaginal atrophy, especially:

Before pessary insertion
Before surgery
For vaginal dryness and irritation
To improve comfort and epithelial health

It does not by itself correct prolapse.

B. Pessary treatment

A pessary is an intravaginal device that supports prolapsed organs.

Indications

Patient does not want surgery
Pregnancy or desire to defer surgery
Elderly or medically unfit patient
Temporary management before surgery
Patient awaiting optimization of comorbidities
Recurrent prolapse
Woman wishing to retain fertility

Common types

Pessary	Usual use
Ring pessary with or without support	Mild to moderate cystocele or uterine prolapse
Hodge pessary	Cystocele, uterine displacement
Shelf pessary	More advanced uterovaginal prolapse
Gellhorn pessary	Advanced prolapse, especially if ring fails
Donut pessary	Severe prolapse or wide introitus
Cube pessary	Advanced prolapse, but needs frequent removal

Principles of fitting

Empty bladder.
Select the largest comfortable pessary that remains retained.
It should support prolapse without causing pain or pressure.
Patient should be able to void normally.
Reassess for discomfort, erosion, discharge, bleeding, and retention.

Complications of pessary

Vaginal discharge
Foul odor
Vaginal ulceration or erosion
Bleeding
Infection
Embedded or incarcerated pessary if neglected
Rarely, fistula formation

Regular follow-up and vaginal examination are essential.

14. Surgical management

Surgery is offered for bothersome symptomatic prolapse when conservative measures are unsuitable, ineffective, or declined.

General surgical principles

Correct all significant compartment defects.
Ensure apical support.
Treat associated urinary or bowel dysfunction appropriately.
Decide whether uterus should be preserved or removed.
Choose reconstructive versus obliterative surgery.
Counsel regarding recurrence, sexual function, operative risks, and mesh-related issues.

A. Vaginal hysterectomy with pelvic floor repair

This is a traditional operation for completed-family women with uterovaginal prolapse.

Components

Vaginal hysterectomy
Apical suspension, often uterosacral ligament suspension or McCall culdoplasty
Anterior colporrhaphy if cystocele is significant
Posterior colporrhaphy and perineorrhaphy if rectocele/perineal deficiency is present
Enterocele repair if present

Important point

A vaginal hysterectomy alone is not an adequate prolapse repair. The vaginal vault must be supported to reduce future vault prolapse.

B. Anterior colporrhaphy

Indication

Anterior vaginal wall prolapse, especially central cystocele.

Principle

Vaginal epithelium is separated from the underlying pubocervical fascia.
Defective fascia is plicated in the midline.
Excess vaginal epithelium is trimmed if needed.
Vaginal wall is closed.

Limitation

Recurrence can occur, particularly if apical or lateral defects are unrecognized.

C. Paravaginal repair

Indication

Lateral defect cystocele due to detachment of pubocervical fascia from pelvic sidewall.

Principle

Reattach the lateral vaginal fascia to the arcus tendineus fascia pelvis.

May be performed vaginally, abdominally, laparoscopically, or robotically depending on setting and expertise.

D. Posterior colporrhaphy

Indication

Symptomatic rectocele with posterior vaginal wall defect.

Principle

Dissect posterior vaginal epithelium off rectovaginal fascia.
Plicate the fascial defect in the midline.
Repair deficient perineal body by perineorrhaphy where required.

Caution

Over-tightening may cause dyspareunia. Repair should target symptoms and anatomical defects, not merely narrow the vagina.

E. McCall culdoplasty

Performed commonly at vaginal hysterectomy.

Purpose

Obliterates or reduces the cul-de-sac.
Supports vaginal vault.
Helps prevent enterocele and vault prolapse.

It involves incorporating uterosacral ligaments and vaginal cuff support.

F. Sacrospinous ligament fixation

Indications

Vaginal vault prolapse
Uterine prolapse, often after vaginal hysterectomy
Recurrent apical prolapse

Principle

The vaginal apex is attached to the sacrospinous ligament, commonly on the right side.

Advantages

Vaginal approach
Avoids abdominal incision
Useful in older or comorbid women

Possible complications

Buttock pain
Hemorrhage
Nerve injury
Vaginal axis deviation
Dyspareunia
Recurrence, especially anterior compartment recurrence

G. Uterosacral ligament suspension

The vaginal apex is suspended to the uterosacral ligaments.

Advantages

Restores relatively central vaginal axis
Can be done at vaginal hysterectomy or for vault prolapse

Important risk

The ureters run close to the uterosacral ligaments. Cystoscopy to confirm ureteric patency is often used after suture placement.

H. Sacrocolpopexy

Indications

Post-hysterectomy vaginal vault prolapse
Advanced apical prolapse
Recurrent prolapse
Sexually active woman desiring maximal vaginal length and support

Principle

A mesh strip attaches the vaginal apex to the anterior longitudinal ligament over the sacral promontory, usually by abdominal, laparoscopic, or robotic approach.

Advantages

Strong and durable apical support
Maintains vaginal length
Lower recurrence for apical prolapse in many settings

Risks

Bowel, bladder, ureteric, or vascular injury
Ileus or bowel obstruction
Mesh exposure or erosion
Sacral osteomyelitis, rare
Thromboembolism
Pain and dyspareunia

I. Uterus-preserving procedures, hysteropexy

These are options for women wishing to preserve the uterus.

Examples:

Sacrospinous hysteropexy
Uterosacral hysteropexy
Sacrohysteropexy
Laparoscopic hysteropexy
Manchester-Fothergill operation in selected cases

Before uterine preservation, evaluate for abnormal uterine bleeding, cervical disease, endometrial pathology, fibroids, and risk factors for uterine malignancy.

J. Manchester-Fothergill operation

Traditional indication

Young woman with:

Uterine prolapse
Cervical elongation, especially supravaginal elongation
Desire to preserve uterus and menstrual function
No desire for immediate fertility, although fertility may remain possible

Main steps

Amputation of elongated cervix.
Plication and shortening of cardinal ligaments in front of cervical stump.
Anterior colporrhaphy if required.
Posterior colpoperineorrhaphy if required.

Drawbacks and concerns

Cervical stenosis
Dysmenorrhea
Infertility or subfertility
Cervical incompetence or obstetric complications in future pregnancy
Persistent or recurrent prolapse

Thus, careful patient selection and counselling are necessary.

K. Le Fort partial colpocleisis

Indications

Elderly woman
Severe prolapse
No desire for future vaginal intercourse
High anesthetic or surgical risk where a shorter obliterative procedure is preferred

Principle

Anterior and posterior vaginal walls are partially denuded and sutured together, leaving lateral drainage channels.

Advantages

Short operation
Effective for advanced prolapse
Less invasive than reconstructive procedures

Contraindication

Desire to retain penetrative vaginal sexual intercourse.

A proper assessment of cervix and uterus is required before surgery because subsequent vaginal access is limited.

15. Mesh in prolapse surgery

Mesh requires specific counselling.

Transvaginal mesh for prolapse has been associated with exposure, erosion, pain, dyspareunia, infection, bleeding, and need for repeat surgery.
In several jurisdictions, transvaginal mesh for POP has been restricted or withdrawn from routine use.
Abdominal or laparoscopic mesh sacrocolpopexy is different from transvaginal mesh placement and remains an option in selected patients.
Mesh should be used only after informed consent and by an appropriately trained surgeon.

The ACOG practice bulletin emphasizes individualized, symptom-directed management and careful counselling about each surgical option.

Recent systematic reviews compare laparoscopic pectopexy with sacrocolpopexy, but these do not replace established individualized decision-making. Relevant recent reviews include PMIDs 39441550 and 40494173.

16. Management according to patient profile

A. Young woman desiring future childbearing

Prefer conservative management when possible.
Pelvic floor physiotherapy.
Pessary where appropriate.
Correct chronic cough, constipation, obesity, and heavy lifting.
Defer definitive surgery until family is complete if symptoms permit.
If surgery is unavoidable, consider uterus-preserving options after specialist counselling.

B. Completed family, symptomatic uterovaginal prolapse

Common choices:

Vaginal hysterectomy with apical suspension
Anterior and/or posterior repair as required
Laparoscopic or abdominal sacrocolpopexy in selected cases
Uterus-preserving hysteropexy if preferred and appropriate

C. Elderly woman who is not sexually active

Options:

Pessary if suitable
Le Fort colpocleisis for advanced symptomatic prolapse if no future vaginal intercourse is desired
Vaginal reconstructive surgery if medically fit and desired

D. Medically unfit patient

Pessary
Vaginal estrogen if atrophic
Treatment of cough and constipation
Pelvic floor exercises
Regular surveillance for ulceration and urinary complications

17. Prevention

Good antenatal and intrapartum care
Avoid unnecessary traumatic vaginal delivery
Proper repair of episiotomy and perineal tears
Timely diagnosis and repair of obstetric anal sphincter injury
Pelvic floor muscle exercises after childbirth
Weight optimization
Treatment of chronic cough and constipation
Avoid repeated heavy lifting
Smoking cessation
Apical support at the time of hysterectomy when indicated

18. High-yield viva points

What is the most important symptom of prolapse?

Sensation of a vaginal bulge or something coming out per vaginam.

What is procidentia?

Complete prolapse of the uterus with eversion of the vagina outside the introitus.

What is a cystocele?

Herniation of bladder through the anterior vaginal wall due to a pubocervical fascial defect.

What is a rectocele?

Herniation of rectum through the posterior vaginal wall due to rectovaginal fascial or perineal-body weakness.

What is an enterocele?

Herniation of peritoneal sac, often containing small bowel, into the upper posterior vaginal wall.

What is vault prolapse?

Descent of the vaginal apex after hysterectomy.

What is the major support of uterus?

The pelvic floor, especially levator ani, together with uterosacral-cardinal ligament complex and endopelvic fascial supports.

What is occult stress urinary incontinence?

Stress incontinence that becomes demonstrable only after reduction of advanced prolapse.

What is the standard modern staging system?

POP-Q system.

What is the key principle in surgery?

Repair all relevant compartment defects and provide adequate apical support.

19. One-paragraph exam conclusion

Genital prolapse is a multifactorial pelvic-floor disorder caused by weakening or injury to the levator ani, perineal body, endopelvic fascia, and uterosacral-cardinal ligament complex. It may involve anterior, apical, and posterior vaginal compartments, producing cystocele, uterine or vault prolapse, rectocele, and enterocele. Diagnosis is clinical, supported by compartment-wise examination and POP-Q staging. Treatment is individualized according to symptoms, age, fitness, sexual activity, fertility wishes, and associated urinary or bowel dysfunction. Conservative care includes pelvic-floor rehabilitation, correction of risk factors, topical estrogen when indicated, and pessaries. Definitive surgery may involve native-tissue repair, vaginal hysterectomy with vault suspension, hysteropexy, sacrospinous fixation, sacrocolpopexy, or colpocleisis in selected elderly women.
