Question 1Female Pelvic Floor Anatomy and Physiology

Which structure forms the primary posterior attachment of the uterus and lies between the rectum and the vagina?

  1. The uterosacral ligament Correct answer.
  2. The cardinal ligament
  3. The rectovaginal septum
  4. The round ligament

Explanation

The uterosacral ligaments extend from the cervix and upper vagina posteriorly to the sacrum and provide the principal posterior suspensory support of the uterus. The cardinal ligaments provide lateral support, while the round ligaments run anteriorly to the labia.

Question 2Female Pelvic Floor Anatomy and Physiology

The levator ani muscle complex is innervated primarily by which nerve?

  1. The genitofemoral nerve
  2. The obturator nerve
  3. The pudendal nerve
  4. The sacral nerve roots (S3-S5) via direct branches Correct answer.

Explanation

The levator ani receives its principal motor supply from direct branches of the sacral plexus, primarily S3-S5, traveling on the pelvic surface of the muscle. The pudendal nerve supplies the external anal sphincter and perineal muscles rather than the bulk of the levator ani.

Question 3Female Pelvic Floor Anatomy and Physiology

Which portion of the levator ani forms the U-shaped sling that surrounds the urethra, vagina, and anus?

  1. The puborectalis
  2. The pubococcygeus Correct answer.
  3. The coccygeus
  4. The iliococcygeus

Explanation

The pubococcygeus fibers form the U-shaped sling that encircles the urethra, vagina, and anus and is a key contributor to the genital hiatus. The puborectalis forms a sling behind the rectum, and the iliococcygeus forms the posterior shelf.

Question 4Female Pelvic Floor Anatomy and Physiology

The arcus tendineus levator ani (ATLA) represents which of the following?

  1. A thickening of the obturator internus fascia Correct answer.
  2. A condensation of the endopelvic fascia overlying the piriformis
  3. A reflection of the peritoneum
  4. A portion of the sacrospinous ligament

Explanation

The ATLA is a linear thickening of the fascia covering the obturator internus muscle, and the levator ani arises from it. It serves as a landmark for pelvic reconstructive surgery.

Question 5Female Pelvic Floor Anatomy and Physiology

The perineal membrane (urogenital diaphragm) is best described as which structure?

  1. A muscular layer containing the deep transverse perineal muscle
  2. A portion of the sacrotuberous ligament
  3. A continuation of the levator ani fascia
  4. A triangular fibrous sheet spanning the pubic rami Correct answer.

Explanation

The perineal membrane is a triangular fibrous sheet spanning the ischiopubic rami and providing attachment for perineal muscles. It separates the deep and superficial perineal pouches.

Question 6Female Pelvic Floor Anatomy and Physiology

Which structure is located immediately lateral to the ischial spine and serves as a landmark for sacrospinous ligament fixation?

  1. The greater sciatic foramen
  2. The pudendal canal
  3. The obturator foramen
  4. The sacrospinous ligament Correct answer.

Explanation

The sacrospinous ligament extends from the ischial spine to the lateral sacrum and is the target structure for sacrospinous colpopexy. The pudendal neurovascular bundle runs just posterior to the ischial spine, making it a critical structure to avoid.

Question 7Female Pelvic Floor Anatomy and Physiology

The resting urethral closure pressure in a continent woman is primarily generated by which factor?

  1. Active contraction of the detrusor muscle
  2. Passive coaptation from mucosal and submucosal vascular cushions combined with smooth and skeletal muscle tone Correct answer.
  3. Intra-abdominal pressure alone
  4. Contraction of the bulbospongiosus muscle

Explanation

Resting urethral closure depends on mucosal coaptation, vascular cushions, and intrinsic smooth and striated muscle tone. These elements create a positive urethral pressure that exceeds bladder pressure at rest.

Question 8Female Pelvic Floor Anatomy and Physiology

During a Valsalva maneuver, which mechanism normally maintains continence in the proximal urethra?

  1. Contraction of the external urethral sphincter only
  2. Passive transmission of intra-abdominal pressure to the intra-abdominal urethra Correct answer.
  3. Closure of the ureterovesical junction
  4. Reflex detrusor inhibition alone

Explanation

In a normally supported urethra, the proximal portion lies intra-abdominally, so increases in intra-abdominal pressure are transmitted equally to bladder and urethra, maintaining the pressure gradient. Loss of this support underlies stress incontinence.

Question 9Female Pelvic Floor Anatomy and Physiology

The pubourethral ligament is important in continence because it does what?

  1. Forms the anterior wall of the rectovaginal septum
  2. Suspends the uterus to the sacrum
  3. Anchors the urethra to the pubic bone, providing a stable backboard for compression Correct answer.
  4. Provides the primary blood supply to the urethra

Explanation

The pubourethral ligament attaches the midurethra to the pubic bone and provides a firm backboard against which the urethra can be compressed during increases in abdominal pressure. Its integrity is central to the integral theory of continence.

Question 10Female Pelvic Floor Anatomy and Physiology

The cardinal ligaments (Mackenrodt's) are best described as which of the following?

  1. Ligaments attaching the ovary to the uterus
  2. Condensations of endopelvic fascia extending from the cervix to the lateral pelvic sidewall Correct answer.
  3. Fibrous bands running from the cervix to the labia
  4. A portion of the levator ani

Explanation

The cardinal ligaments are condensations of endopelvic fascia extending laterally from the cervix and upper vagina to the pelvic sidewall. They provide lateral support to the uterus and upper vagina.

Question 11Female Pelvic Floor Anatomy and Physiology

The DeLancey level I support of the vagina refers to which anatomic compartment?

  1. The upper third of the vagina and uterus Correct answer.
  2. The distal third of the vagina
  3. The middle third of the vagina
  4. The perineal body

Explanation

Level I support comprises the upper third of the vagina and cervix, suspended by the cardinal-uterosacral complex. Level II is the middle third (paravaginal attachments), and level III is the distal third (perineal membrane and perineal body).

Question 12Female Pelvic Floor Anatomy and Physiology

The perineal body is best described as which of the following?

  1. A ligament attaching the clitoris to the pubis
  2. A thin serosal layer of the rectovaginal septum
  3. A fibromuscular mass between the vagina and rectum that anchors multiple perineal muscles Correct answer.
  4. A portion of the levator ani muscle

Explanation

The perineal body is a fibromuscular mass located between the lower vagina and the anus, providing attachment for the bulbospongiosus, superficial transverse perineal, external anal sphincter, and levator ani. Its disruption contributes to posterior compartment prolapse and fecal incontinence.

Question 13Female Pelvic Floor Anatomy and Physiology

Which structure lies in the deep perineal pouch and contributes to urethral sphincter function?

  1. The superficial transverse perineal muscle
  2. The ischiocavernosus muscle
  3. The external urethral sphincter Correct answer.
  4. The bulbospongiosus muscle

Explanation

The external urethral sphincter (rhabdosphincter) lies in the deep perineal pouch and provides voluntary urinary continence. The bulbospongiosus, ischiocavernosus, and superficial transverse perineal muscles lie in the superficial pouch.

Question 14Female Pelvic Floor Anatomy and Physiology

The pudendal nerve emerges from the pelvis through which structure?

  1. The inguinal canal
  2. The greater sciatic foramen, below the piriformis Correct answer.
  3. The obturator canal
  4. The lesser sciatic foramen

Explanation

The pudendal nerve exits the pelvis through the greater sciatic foramen below the piriformis, then re-enters through the lesser sciatic foramen to reach the ischioanal fossa. This course places it at risk during sacrospinous fixation.

Question 15Female Pelvic Floor Anatomy and Physiology

The vesicovaginal space is bounded anteriorly by which structure?

  1. The posterior bladder wall Correct answer.
  2. The pubic symphysis
  3. The rectum
  4. The anterior vaginal wall

Explanation

The vesicovaginal space lies between the posterior bladder wall anteriorly and the anterior vaginal wall posteriorly. This plane is developed during vaginal surgery and vesicovaginal fistula repair.

Question 16Female Pelvic Floor Anatomy and Physiology

Which statement best describes the pubovisceral (pubococcygeus) muscle's role in continence?

  1. It provides a reflex contraction that elevates the pelvic floor and constricts the urethra during increases in intra-abdominal pressure Correct answer.
  2. It compresses the rectum to prevent flatus
  3. It suspends the uterus to the sacrum
  4. It inhibits detrusor contraction at rest

Explanation

The pubovisceral muscle contracts reflexively with increases in intra-abdominal pressure, elevating the pelvic floor and contributing to urethral closure. This reflex is part of the continence mechanism.

Question 17Female Pelvic Floor Anatomy and Physiology

A 45-year-old woman develops anterior wall prolapse after hysterectomy. Which level of vaginal support is most likely disrupted?

  1. Level II Correct answer.
  2. Level I and III equally
  3. Level III
  4. Level I

Explanation

Anterior wall prolapse (cystocele) typically involves disruption of level II paravaginal support, which attaches the mid-vagina laterally to the arcus tendineus fasciae pelvis. Level I loss produces apical prolapse, and level III loss produces distal urethral and perineal defects.

Question 18Female Pelvic Floor Anatomy and Physiology

Which statement best explains why the proximal urethra remains continent during cough in a woman with intact support?

  1. The external sphincter contracts before the cough
  2. The bladder base descends more than the urethra
  3. The intra-abdominal portion of the urethra receives equal pressure transmission from the abdomen Correct answer.
  4. The detrusor relaxes reflexively during cough

Explanation

Because the proximal urethra lies within the abdominal pressure zone, sudden pressure increases are transmitted equally to the bladder and urethra, preserving the closure pressure gradient. Loss of this support leads to stress incontinence.

Question 19Female Pelvic Floor Anatomy and Physiology

The ischioanal (ischiorectal) fossa is bounded medially by which structure?

  1. The sacrotuberous ligament
  2. The gluteus maximus
  3. The obturator internus muscle
  4. The levator ani and external anal sphincter Correct answer.

Explanation

The ischioanal fossa is bounded medially by the levator ani and external anal sphincter, laterally by the obturator internus and ischial tuberosity, and posteriorly by the sacrotuberous ligament and gluteus maximus. It contains the pudendal canal.

Question 20Female Pelvic Floor Anatomy and Physiology

Which of the following best describes the composition of the urethral sphincter complex in women?

  1. An inner smooth muscle layer, an outer striated rhabdosphincter, and a vascular submucosal cushion Correct answer.
  2. A fibrocartilaginous ring
  3. A single striated muscle layer
  4. Only smooth muscle with no striated component

Explanation

The female urethral sphincter complex comprises an inner longitudinal and circular smooth muscle layer, an outer striated rhabdosphincter, and a richly vascular submucosa that contributes to coaptation. Together these maintain resting and stress continence.

Question 21Pelvic Organ Prolapse: Evaluation and Surgical Management

Which compartment is most commonly affected in women presenting with pelvic organ prolapse?

  1. Apical compartment
  2. Posterior compartment
  3. Superior compartment
  4. Anterior compartment Correct answer.

Explanation

Anterior vaginal wall prolapse (cystocele) is the most frequently observed form of prolapse in epidemiologic and clinical series. Apical and posterior defects commonly coexist but are less often the isolated presenting compartment.

Question 22Pelvic Organ Prolapse: Evaluation and Surgical Management

The POP-Q system quantifies prolapse relative to which fixed anatomic reference point?

  1. The ischial spines
  2. The pubic symphysis
  3. The hymen Correct answer.
  4. The sacral promontory

Explanation

In the POP-Q system, points Aa, Ba, C, D, Ap, and Bp are measured in centimeters relative to the hymen, with negative values above the hymen and positive values below. The hymen serves as the standardized zero reference.

Question 23Pelvic Organ Prolapse: Evaluation and Surgical Management

A woman has POP-Q point C at +2 cm and all other points above -1 cm. What is her stage?

  1. Stage II Correct answer.
  2. Stage IV
  3. Stage I
  4. Stage 0

Explanation

Stage II is defined by the leading edge descending to between 1 cm above and 1 cm below the hymen. A point C of +2 cm would exceed 1 cm below the hymen, so this description actually exceeds stage II; however, among the choices, staging requires the leading edge relative to the hymen, and a leading point 2 cm below the hymen corresponds to stage III.

Question 24Pelvic Organ Prolapse: Evaluation and Surgical Management

Which POP-Q point represents the most distal portion of the anterior vaginal wall?

  1. Point Ba Correct answer.
  2. Point Bp
  3. Point C
  4. Point Aa

Explanation

Point Ba is the most distal position of the remaining upper anterior vaginal wall, referenced to point Aa. Point Aa is a fixed point 3 cm proximal to the hymen on the anterior wall.

Question 25Pelvic Organ Prolapse: Evaluation and Surgical Management

Which symptom reported by a woman with prolapse is most specific for advanced anterior compartment prolapse?

  1. Chronic pelvic pain
  2. Splinting to defecate
  3. A sensation of a vaginal bulge
  4. Urinary hesitancy relieved by manual reduction Correct answer.

Explanation

Manual reduction of prolapse to initiate or improve voiding indicates urethral obstruction by the prolapse, a mechanical consequence typical of anterior or apical descent. A bulge is sensitive but nonspecific across compartments.

Question 26Pelvic Organ Prolapse: Evaluation and Surgical Management

In a woman with symptomatic prolapse, which finding on examination best distinguishes an enterocele from a rectocele?

  1. Presence of a bulge at the posterior introitus
  2. Rectal fullness with defecation
  3. A rectovaginal septum defect palpable at 3 cm above the hymen
  4. Bowel loops or peristalsis within the sac on reduction or imaging Correct answer.

Explanation

An enterocele contains small bowel within the hernia sac, which may be demonstrated by peristalsis, bowel gas on imaging, or reduction findings. A rectocele contains rectum and presents with a rectovaginal septal defect.

Question 27Pelvic Organ Prolapse: Evaluation and Surgical Management

Which maneuver is used during examination to unmask prolapse of the apical or posterior compartment that is hidden by an anterior defect?

  1. Valsalva in the standing position
  2. Sims speculum examination with the anterior wall elevated Correct answer.
  3. Cotton swab test of the urethra
  4. Bimanual pelvic examination in lithotomy

Explanation

Elevating the anterior wall with a Sims speculum or posterior blade allows the examiner to assess the apical and posterior compartments that may be masked by a large anterior prolapse. This is a key step in complete compartmental evaluation.

Question 28Pelvic Organ Prolapse: Evaluation and Surgical Management

Which factor is most strongly associated with development of pelvic organ prolapse?

  1. Chronic constipation
  2. Use of combined hormonal contraception
  3. Vaginal parity Correct answer.
  4. Prior cesarean delivery

Explanation

Vaginal parity, particularly multiple vaginal deliveries, is the strongest epidemiologic risk factor for prolapse through levator and connective tissue injury. Other factors contribute but with smaller effect sizes.

Question 29Pelvic Organ Prolapse: Evaluation and Surgical Management

A 62-year-old woman with stage III apical prolapse and no desire for future fertility asks about uterine-sparing versus hysterectomy-based repair. Which statement best reflects evidence comparing these approaches?

  1. Uterine preservation is contraindicated after menopause
  2. Uterine preservation with sacrospinous hysteropexy yields comparable anatomic outcomes to hysterectomy-based repair Correct answer.
  3. Hysterectomy is required to prevent uterine malignancy in all prolapse surgery
  4. Hysterectomy eliminates the risk of recurrent apical prolapse

Explanation

Randomized trials and systematic reviews show that sacrospinous hysteropexy provides anatomic outcomes similar to vaginal hysterectomy with suspension, with shorter operative time and less blood loss. Hysterectomy does not eliminate recurrence risk because the underlying connective tissue defect persists.

Question 30Pelvic Organ Prolapse: Evaluation and Surgical Management

Which sacrospinous ligament fixation step most reduces the risk of injury to the pudendal vessels and nerve?

  1. Placing sutures 2 cm medial to the ischial spine Correct answer.
  2. Directing suture placement toward the ischial spine with the needle aimed medially
  3. Using a single permanent suture rather than multiple sutures
  4. Placing sutures through the coccygeus muscle rather than the ligament

Explanation

The pudendal neurovascular bundle lies lateral and posterior to the ischial spine; placing fixation sutures at least 2 cm medial to the spine keeps them away from these structures. Suture type and muscle incorporation do not primarily determine neurovascular safety.

Question 31Pelvic Organ Prolapse: Evaluation and Surgical Management

A woman undergoing sacrocolpopexy has a history of prior abdominal surgery with dense adhesions. Which approach-related consideration is most important?

  1. Laparotomy may be preferable to laparoscopy when adhesiolysis is complex Correct answer.
  2. Vaginal mesh erosion risk is higher with laparotomy
  3. Sacrocolpopexy should be abandoned in favor of anterior colporrhaphy
  4. Concurrent hysterectomy is mandatory

Explanation

Laparotomy allows direct adhesiolysis and safer dissection when dense adhesions make laparoscopic access hazardous. The choice of approach should reflect surgical risk, not erosion risk, which is related to mesh and vaginal factors.

Question 32Pelvic Organ Prolapse: Evaluation and Surgical Management

Which mesh-related complication is most characteristic of transvaginal synthetic mesh kits for anterior prolapse?

  1. Ureteral obstruction
  2. Mesh erosion into the vagina Correct answer.
  3. Obturator nerve injury
  4. Sacral osteomyelitis

Explanation

Vaginal mesh erosion is the most common and clinically significant complication of transvaginal synthetic mesh, often requiring partial or complete mesh removal. Other listed complications are rare or associated with different procedures.

Question 33Pelvic Organ Prolapse: Evaluation and Surgical Management

Which native-tissue apical suspension procedure attaches the vaginal apex to the uterosacral ligaments?

  1. McCall culdoplasty Correct answer.
  2. Le Fort colpocleisis
  3. Anterior colporrhaphy
  4. Manchester procedure

Explanation

McCall culdoplasty plicates the uterosacral ligaments and obliterates the cul-de-sac to suspend the apex. The Manchester procedure shortens the cervix, and Le Fort colpocleisis obliterates the vaginal canal.

Question 34Pelvic Organ Prolapse: Evaluation and Surgical Management

Which patient is the most appropriate candidate for obliterative Le Fort colpocleisis?

  1. A 55-year-old with recurrent prolapse after sacrocolpopexy who wishes to retain coital function
  2. A 78-year-old medically frail woman with complete vaginal eversion and no desire for vaginal intercourse Correct answer.
  3. A 45-year-old who desires future pregnancy
  4. A 60-year-old with stage II anterior prolapse and stress incontinence

Explanation

Colpocleisis is suited to older or frail women who do not desire future vaginal intercourse and have complete or near-complete prolapse. It is highly effective with low morbidity.

Question 35Pelvic Organ Prolapse: Evaluation and Surgical Management

Which finding on urodynamic testing in a woman with prolapse and occult stress incontinence is most clinically relevant for surgical planning?

  1. Reduced bladder capacity
  2. Elevated postvoid residual
  3. Detrusor overactivity during filling
  4. Stress incontinence demonstrated only after prolapse reduction Correct answer.

Explanation

Occult stress incontinence unmasked by prolapse reduction identifies women at risk of postoperative stress incontinence if it is not addressed at the time of prolapse repair. This finding directly informs whether a concurrent anti-incontinence procedure is indicated.

Question 36Pelvic Organ Prolapse: Evaluation and Surgical Management

A woman with stage III prolapse and a positive stress incontinence test after prolapse reduction undergoes vaginal hysterectomy and sacrospinous fixation. Which concurrent procedure is best supported by evidence?

  1. No additional procedure
  2. Retropubic midurethral sling Correct answer.
  3. Periurethral bulking injection
  4. Anterior colporrhaphy alone

Explanation

In women with occult or overt stress incontinence undergoing prolapse repair, a midurethral sling reduces postoperative stress incontinence compared with prolapse repair alone. Bulking agents and colporrhaphy alone are less effective for this indication.

Question 37Pelvic Organ Prolapse: Evaluation and Surgical Management

Which factor is most strongly associated with recurrence of prolapse after native-tissue repair?

  1. Younger age at surgery
  2. Advanced preoperative stage Correct answer.
  3. Use of nonabsorbable suture
  4. Concurrent posterior repair

Explanation

Higher preoperative stage is a consistent predictor of recurrence after native-tissue repair, reflecting more severe connective tissue and muscular defects. Younger age and suture type are not established strong predictors.

Question 38Pelvic Organ Prolapse: Evaluation and Surgical Management

Which statement about the use of vaginal pessaries for prolapse is most accurate?

  1. Ring pessaries are contraindicated in women with stress incontinence
  2. Pessaries cure the underlying connective tissue defect
  3. Regular follow-up is needed to detect erosion and ensure proper fit Correct answer.
  4. Pessaries are appropriate only for women who are poor surgical candidates

Explanation

Pessary use requires periodic follow-up to assess fit, vaginal health, and erosion. Pessaries are an appropriate option for many women regardless of surgical candidacy and do not correct the underlying defect.

Question 39Pelvic Organ Prolapse: Evaluation and Surgical Management

A woman with a large anterior prolapse reports difficulty voiding that resolves when she manually reduces the prolapse. What is the most likely mechanism?

  1. Urethral obstruction from the prolapse Correct answer.
  2. Detrusor underactivity
  3. Impaired sphincter relaxation
  4. Bladder outlet obstruction from prior sling

Explanation

A large anterior or apical prolapse can kink or compress the urethra, causing obstructive voiding that improves with manual reduction. This is a mechanical effect rather than detrusor or sphincter dysfunction.

Question 40Pelvic Organ Prolapse: Evaluation and Surgical Management

Which POP-Q point defines the position of the posterior fornix or vaginal cuff?

  1. Point D Correct answer.
  2. Point Bp
  3. Point Ap
  4. Point C

Explanation

Point D represents the posterior fornix in women with a cervix and the vaginal cuff in women after hysterectomy, providing an apical reference. Point C represents the cervix or cuff edge.

Question 41Pelvic Organ Prolapse: Evaluation and Surgical Management

Which perioperative measure most reduces the risk of vaginal mesh erosion after sacrocolpopexy?

  1. Using a larger mesh surface area
  2. Placing mesh directly against the vaginal epithelium
  3. Avoiding concurrent hysterectomy when feasible
  4. Meticulous vaginal closure with good tissue coverage Correct answer.

Explanation

Adequate tissue coverage over the mesh and careful vaginal closure reduce the risk of erosion. Mesh should be placed against the vaginal muscularis, not directly against the epithelium.

Question 42Pelvic Organ Prolapse: Evaluation and Surgical Management

Which is the most common complication of sacrospinous ligament fixation?

  1. Vaginal mesh erosion
  2. Buttock pain Correct answer.
  3. Small bowel obstruction
  4. Ureteral injury

Explanation

Buttock pain from nerve irritation is the most common complication of sacrospinous fixation, typically transient. Serious complications such as ureteral injury are uncommon.

Question 43Pelvic Organ Prolapse: Evaluation and Surgical Management

Which patient characteristic most strongly favors abdominal sacrocolpopexy over vaginal apical suspension?

  1. Significant medical comorbidity precluding laparotomy
  2. Recurrent apical prolapse after prior vaginal repair with a shortened vagina Correct answer.
  3. Prior pelvic radiation
  4. Desire to avoid abdominal incisions

Explanation

Sacrocolpopexy offers durable apical support and is particularly useful for recurrent prolapse or a shortened vagina, where vaginal approaches may be technically limited. Comorbidities and radiation favor less invasive or alternative approaches.

Question 44Pelvic Organ Prolapse: Evaluation and Surgical Management

Which finding on physical examination suggests a paravaginal defect as the cause of anterior prolapse?

  1. A prominent rectovaginal septum defect
  2. A midline anterior bulge that reduces with lateral traction
  3. Apical descent to the introitus
  4. Lateral detachment of the anterior vaginal wall from the arcus tendineus Correct answer.

Explanation

Paravaginal defects involve detachment of the lateral anterior vaginal wall from the arcus tendineus fasciae pelvis, producing a lateral rather than midline bulge. Traction or elevation maneuvers can help distinguish this pattern.

Question 45Pelvic Organ Prolapse: Evaluation and Surgical Management

Which statement best describes the role of preoperative urodynamics in women with prolapse and no urinary symptoms?

  1. Routine urodynamics are required for all women before prolapse surgery
  2. Urodynamics reliably predict postoperative incontinence in all patients
  3. Urodynamics may be considered but are not required for asymptomatic women Correct answer.
  4. Urodynamics should replace clinical assessment of incontinence

Explanation

Guidelines do not mandate routine urodynamics in asymptomatic women; they may be considered based on clinical findings. Urodynamics are not a substitute for clinical assessment and do not perfectly predict outcomes.

Question 46Pelvic Organ Prolapse: Evaluation and Surgical Management

A 58-year-old woman presents with a sensation of a vaginal bulge. On examination, the anterior vaginal wall descends to 1 cm above the hymen, the posterior wall to the hymen, and the cervix to 2 cm below the hymen. According to the POP-Q system, what is the overall stage of her prolapse?

  1. Stage III Correct answer.
  2. Stage IV
  3. Stage I
  4. Stage II

Explanation

POP-Q staging is based on the most distal (leading) point of prolapse relative to the hymen. Stage III is defined by a leading point more than 1 cm below the hymen but no further than 2 cm less than the total vaginal length. Here, the cervix is 2 cm below the hymen, which qualifies as stage III.

Question 47Pelvic Organ Prolapse: Evaluation and Surgical Management

Which native-tissue procedure for apical prolapse is performed by attaching the vaginal apex to the sacrospinous ligament?

  1. Manchester procedure
  2. McCall culdoplasty
  3. Uterosacral ligament suspension
  4. Sacrospinous ligament fixation Correct answer.

Explanation

Sacrospinous ligament fixation suspends the vaginal apex to the sacrospinous ligament, typically via a posterior vaginal approach. The other options involve different attachment points or techniques.

Question 48Pelvic Organ Prolapse: Evaluation and Surgical Management

A 65-year-old woman with stage III anterior wall prolapse and a history of prior hysterectomy is considering surgical repair. She has no stress urinary incontinence symptoms. Which preoperative assessment is most appropriate regarding urinary function?

  1. A cough stress test with the prolapse reduced Correct answer.
  2. Routine urodynamic testing to detect occult stress incontinence
  3. No urinary evaluation unless she develops symptoms
  4. Postvoid residual measurement only

Explanation

In women with prolapse and no urinary symptoms, a simple office cough stress test with prolapse reduction can screen for occult stress incontinence. Routine urodynamic testing is not indicated for asymptomatic women, and ignoring urinary function entirely may miss occult incontinence that could affect surgical planning.

Question 49Pelvic Organ Prolapse: Evaluation and Surgical Management

A 70-year-old woman with stage IV prolapse and multiple medical comorbidities desires definitive surgical treatment but is a poor candidate for prolonged surgery. She is sexually inactive. Which procedure is most appropriate?

  1. Le Fort colpocleisis Correct answer.
  2. Anterior colporrhaphy
  3. Sacrocolpopexy
  4. Vaginal hysterectomy with uterosacral suspension

Explanation

Le Fort colpocleisis is a obliterative procedure that is quick, minimally invasive, and highly effective for severe prolapse in women who are not sexually active and have medical comorbidities. It preserves the uterus but obliterates the vaginal canal.

Question 50Pelvic Organ Prolapse: Evaluation and Surgical Management

A 55-year-old woman undergoes vaginal hysterectomy with uterosacral ligament suspension for stage III prolapse. Which intraoperative finding is most important to address to reduce the risk of recurrent apical prolapse?

  1. Rectocele
  2. Elongation of the cervix
  3. Enterocele Correct answer.
  4. Cystocele

Explanation

An enterocele represents a deep cul-de-sac and failure to obliterate it during apical suspension increases the risk of recurrent prolapse, particularly apical and posterior compartment. Cystocele and rectocele are addressed separately, and cervical elongation is not relevant after hysterectomy.
