Pelvic Organ Prolapse: Classification Indian Medical PG Practice Questions and MCQs
Question 1: In young women suffering from 2nd & 3rd degree uterovaginal prolapse, the choice of operation is:
- A. Vaginal hysterectomy with vault suspension
- B. Uterosacral ligament suspension
- C. Manchester repair (Correct Answer)
- D. Laparoscopic sacrohysteropexy
Explanation: ***Manchester repair*** - For **young women** with 2nd and 3rd degree uterovaginal prolapse, **Manchester repair** (Fothergill's operation) is the traditional procedure of choice as it **preserves fertility** while effectively treating the prolapse. - The procedure involves **amputation of the elongated cervix** and **plication of the cardinal ligaments** anteriorly, providing excellent support while maintaining the uterus for future childbearing. - This is particularly suitable for young women who have not completed their family, addressing both the anatomical defect and fertility preservation. *Vaginal hysterectomy with vault suspension* - This is an effective and definitive treatment for uterovaginal prolapse but involves **removal of the uterus**, making it unsuitable as the first choice for young women who may desire future fertility. - This procedure is more appropriate for women who have completed their family or in whom uterine preservation is not a priority. *Laparoscopic sacrohysteropexy* - While this modern procedure preserves the uterus and fertility, it is a **more complex and expensive** minimally invasive approach that may not be widely available in all centers. - Though increasingly used, it is not traditionally considered the standard first-line procedure in examination contexts, where Manchester repair remains the classical fertility-preserving option for young women. *Uterosacral ligament suspension* - This procedure is primarily used for **vaginal vault prolapse** after hysterectomy or as a component of prolapse repair, not as a standalone treatment for uterovaginal prolapse with the uterus in situ. - It does not address the cervical elongation and uterine descent that typically accompany 2nd and 3rd degree uterovaginal prolapse in young women.
Question 2: Injury to which of the following muscles that forms the deep support of the perineal body causes cystocele, enterocele and urethral descent?
- A. Sphincter of urethra and anus
- B. Pubococcygeus (Correct Answer)
- C. Bulbospongiosus
- D. Ischiocavernosus
Explanation: ***Pubococcygeus*** - The **pubococcygeus muscle** is a major component of the **levator ani muscle** group, forming the primary support structure of the pelvic floor [1]. Damage to this muscle impairs the support for the bladder, rectum, and uterus, leading to prolapse conditions like **cystocele**, **enterocele**, and **urethral descent**. - Its integrity is crucial for maintaining the position of pelvic organs and proper function of the urinary and defecatory systems, as it directly supports the vagina, rectum, and bladder neck [3]. *Sphincter of urethra and anus* - The **external urethral sphincter** primarily controls voluntary urination, and its injury mainly leads to **stress urinary incontinence**, not necessarily prolapse [2]. - The **external anal sphincter** controls defecation, and its injury would primarily lead to **fecal incontinence**, not cystocele, enterocele, or urethral descent [2]. *Bulbospongiosus* - The **bulbospongiosus muscle** is superficial, supporting the clitoris and compressing erectile tissue in females, and expelling semen/urine in males. - Its injury would primarily affect sexual function and perineal body integrity but is **not a primary cause of pelvic organ prolapse** like cystocele or enterocele [3]. *Ischiocavernosus* - The **ischiocavernosus muscle** is also superficial, maintaining erection of the clitoris/penis by compressing the crura. - Injury to this muscle would mainly disrupt **erectile function** and contribute minimally to pelvic organ support or prolapse.
Question 3: All are causes of prolapse of cervix EXCEPT:
- A. Menopause
- B. Chronic cough
- C. Delivery of a big baby
- D. Regular exercise (Correct Answer)
Explanation: ***Regular exercise*** - **Regular exercise**, especially core-strengthening exercises, can actually help prevent pelvic organ prolapse by strengthening the **pelvic floor muscles**. - It does not contribute to the weakening of support structures necessary for cervical prolapse. *Menopause* - **Estrogen deficiency** during menopause leads to the thinning and weakening of **pelvic connective tissues** and muscles. - This loss of tissue elasticity and strength renders the pelvic organs more susceptible to prolapse. *Chronic cough* - A **chronic cough** significantly increases **intra-abdominal pressure** repeatedly. - This sustained downward force can strain and weaken the **pelvic floor muscles** and ligaments over time, contributing to prolapse. *Delivery of a big baby* - The **vaginal delivery** of a large baby can cause significant **trauma** and stretching to the **pelvic floor muscles**, ligaments, and fascia. - This physical damage can compromise the structural integrity supporting the cervix and other pelvic organs, increasing the risk of prolapse.
Question 4: A young nulliparous woman has 3rd degree uterovaginal prolapse without any cystocele or rectocele. There is no stress incontinence. Uterocervical length is 3 inches. All other findings are normal. The best treatment plan for her will be :
- A. Fothergill's operation (Correct Answer)
- B. Shirodkar's abdominal sling
- C. Shirodkar's vaginal repair
- D. Observation and reassurance till child bearing is over
Explanation: ***Fothergill's operation*** - This procedure, also known as **Manchester operation**, is the best option for this patient with **3rd degree uterovaginal prolapse** and **elongated cervix (3-inch uterocervical length)**. - It involves **cervical amputation**, plication of the cardinal ligaments, and anterior colporrhaphy, effectively addressing the prolapse while preserving the uterus. - While it preserves the uterus, **cervical amputation may impact fertility**, so thorough counseling is essential. However, for severe prolapse in a young woman, this offers a balance between surgical correction and uterine preservation. - The absence of cystocele and rectocele makes this focused procedure ideal without requiring extensive vaginal wall repair. *Shirodkar's abdominal sling* - This procedure is primarily used for **cervical incompetence** to prevent preterm delivery, not for uterovaginal prolapse. - It involves placing a stitch around the cervix via an abdominal approach and is typically performed during pregnancy. *Shirodkar's vaginal repair* - There is no standard gynecological procedure known as "Shirodkar's vaginal repair" for uterovaginal prolapse. - The Shirodkar procedure is specifically a type of **cervical cerclage** to prevent pregnancy loss due to cervical incompetence. *Observation and reassurance till child bearing is over* - While conservative management with pessary can be considered for women desiring future pregnancies, a **3rd degree uterovaginal prolapse** is a severe condition that typically requires surgical intervention. - Delaying definitive treatment for severe prolapse can lead to discomfort, ulceration, urinary complications, and progressive pelvic floor dysfunction.
Question 5: What is the treatment for uterine prolapse in nulliparous women?
- A. Anterior colporrhaphy
- B. Posterior colporrhaphy
- C. Sling used involving rectus sheath
- D. Manchester operation (Correct Answer)
Explanation: ***Manchester operation*** - This procedure is sometimes considered for **nulliparous women** with uterine prolapse, particularly if combined with cervical elongation. - It involves **amputation of the cervix** and support of the cardinal ligaments, which can address the prolapse while preserving uterine function. *Sling used involving rectus sheath* - A sling using the rectus sheath is typically employed for **stress urinary incontinence**, not primarily for uterine prolapse. - While it supports the urethra and bladder neck, it does not directly address the descent of the uterus. *Anterior colporrhaphy* - This procedure repairs a **cystocele** (prolapse of the bladder into the vagina) by tightening the anterior vaginal wall. - It does not directly manage **uterine prolapse** itself, though a cystocele can coexist with uterine descent. *Posterior colporrhaphy* - This surgical repair targets a **rectocele** (prolapse of the rectum into the vagina) by tightening the posterior vaginal wall. - Similar to anterior colporrhaphy, it addresses a specific vaginal wall defect rather than the **uterine position**.
Question 6: Cystocoele is prolapse of
- A. Lower 1/3 of anterior vaginal wall
- B. Lower 2/3rd of anterior vaginal wall
- C. Upper 1/3 of anterior vaginal wall
- D. Upper 2/3rd of anterior vaginal wall (Correct Answer)
Explanation: ***Upper 2/3rd of anterior vaginal wall*** - A **cystocele** specifically refers to the prolapse of the **bladder** through the **upper two-thirds of the anterior vaginal wall**. - The bladder is primarily supported by the **pubocervical fascia** overlying the upper 2/3rd of the anterior vaginal wall. - When this fascial support weakens, the bladder herniates into the vaginal lumen, creating a cystocele. - This is the **classic anatomical definition** found in standard gynecology textbooks. *Lower 2/3rd of anterior vaginal wall* - This option is anatomically incorrect for defining a pure cystocele. - While severe cystoceles can extend downward, the primary defect involves the upper two-thirds where bladder support is located. *Lower 1/3 of anterior vaginal wall* - Prolapse of the lower 1/3 of the anterior vaginal wall is called a **urethrocele**, which involves prolapse of the **urethra**. - A **cystourethrocele** refers to combined prolapse of both bladder and urethra. - This is distinct from a pure cystocele. *Upper 1/3 of anterior vaginal wall* - While the upper third is involved in cystocele, the complete anatomical definition encompasses the **entire upper two-thirds** (upper 2/3rd), not just the upper one-third. - Limiting it to only the upper 1/3 would be incomplete and anatomically imprecise.
Question 7: The reference point 'zero' in POPQ (Pelvic Organ Prolapse Quantification) classification is taken as
- A. perineal body
- B. ischial spine
- C. hymen (Correct Answer)
- D. mid-vagina
Explanation: ***hymen*** - The **hymen** (or hymenal ring/hymenal caruncles in parous women) is the fixed anatomical reference point (zero point) in the POPQ classification system. - All measurements in POPQ are taken in centimeters relative to the hymenal ring, with **negative values** indicating positions above the hymen and **positive values** indicating descent beyond the hymen. - This landmark was chosen because it is **easily identifiable, reproducible, and remains relatively constant** regardless of the degree of prolapse. *ischial spine* - The **ischial spines** are important anatomical landmarks in the pelvis but are **not** used as the zero reference point in POPQ. - They are used for measuring **total vaginal length (TVL)** - the distance from the hymen to the posterior fornix with the prolapse reduced. - The ischial spines serve as internal palpable landmarks during pelvic examination but not as the measurement reference for prolapse staging. *perineal body* - The **perineal body** is a fibromuscular structure in the perineum and is measured in POPQ (as genital hiatus and perineal body measurements). - However, it is **not the zero reference point** because its position and integrity can be altered by prolapse, childbirth trauma, or surgical procedures. *mid-vagina* - The **mid-vagina** is not a standardized anatomical landmark and is **too variable** to serve as a fixed reference point. - POPQ requires precise, reproducible measurements, which cannot be achieved with such a vague landmark.
Question 8: A 65-year-old P3+0 female complains of procidentia. She has a past history significant for MI and is diabetic and hypertensive. The patient is not sexually active. Ideal management of prolapse in this patient is:
- A. Cervicopexy
- B. Vaginal hysterectomy
- C. Wait and watch
- D. Le Fort's repair (Correct Answer)
Explanation: ***Le Fort's repair*** - This procedure, a **colpocleisis**, involves partially or completely closing the vagina, making it an ideal choice for elderly, non-sexually active women with significant medical comorbidities who require surgical management of severe prolapse. - The goal is symptom relief with a **minimally invasive** procedure, avoiding a major abdominal surgery that might be risky for a patient with a history of MI, diabetes, and hypertension. *Cervicopexy* - This procedure aims to support the cervix, often done in conjunction with uterine preservation for prolapse. - It is typically performed in younger, sexually active women who wish to retain their uterus, which is not the case for this patient. *Vaginal hysterectomy* - While vaginal hysterectomy is a common procedure for uterine prolapse, in this patient with significant comorbidities and who is not sexually active, a less invasive procedure like Le Fort's repair would be preferred to minimize surgical risks. - This procedure removes the uterus and may be combined with efforts to provide apical support; however, it is a more extensive surgery than colpocleisis. *Wait and watch* - Given the complaint of **procidentia**, which represents severe prolapse, a "wait and watch" approach is inappropriate as it implies significant symptoms and risk of complications, such as ulceration or infection. - This approach is typically reserved for women with **mild to moderate prolapse** and minimal symptoms, or those who decline active treatment, which is not indicated here.
Question 9: Following are the risk factors for pelvic organ prolapse, except?
- A. Vaginal childbirth
- B. Hypoestrogenism
- C. Constipation
- D. Crohn's disease (Correct Answer)
Explanation: ***Crohn's disease*** - Crohn's disease is an **inflammatory bowel disease** primarily affecting the gastrointestinal tract and is not directly associated with the development of **pelvic organ prolapse**. - Its effects on the pelvic floor muscles and connective tissues are typically not significant enough to cause prolapse. *Vaginal childbirth* - **Vaginal childbirth**, especially involving multiple deliveries, prolonged labor, or instrumental delivery, is a significant risk factor due to potential damage to pelvic floor muscles and ligaments. - The stretching and tearing of tissues can weaken the support structures for pelvic organs. *Hypoestrogenism* - **Hypoestrogenism**, particularly after menopause, leads to **atrophy of collagen** and elastic tissue in the pelvic floor, reducing tissue strength and support. - Reduced estrogen levels diminish the integrity of vaginal and pelvic connective tissues, increasing susceptibility to prolapse. *Constipation* - **Chronic constipation** involves repeated straining during defecation, which significantly increases **intra-abdominal pressure**. - This persistent downward pressure weakens the pelvic floor muscles and connective tissues over time, contributing to prolapse.
Question 10: Which of the following accurately describes management of Grade 3 pelvic organ prolapse in an elderly woman who is a poor surgical candidate?
- A. Bladder sling
- B. Vaginal hysterectomy
- C. Pessary placement (Correct Answer)
- D. Kegel exercises
Explanation: ***Pessary placement*** - **Pessaries** are a less invasive, effective option for **pelvic organ prolapse** management in patients who are **poor surgical candidates**, helping to support prolapsed organs. - They also serve as a good temporary option to improve symptoms before surgical intervention. *Bladder sling* - A **bladder sling** is a surgical procedure used primarily to treat **stress urinary incontinence**, not pelvic organ prolapse. - This option is unsuitable for a patient who is a **poor surgical candidate**. *Vaginal hysterectomy* - A **vaginal hysterectomy** involves surgical removal of the uterus through the vagina, which is a definitive treatment for **uterine prolapse**. - However, surgical interventions are contraindicated for an **elderly woman** who is a **poor surgical candidate** due to potential risks. *Kegel exercises* - **Kegel exercises** are beneficial for strengthening the **pelvic floor muscles** and preventing the progression of early-stage prolapse or improving mild symptoms. - However, they are generally **insufficient** for managing **Grade 3 pelvic organ prolapse**, which requires more robust support.
