Pelvic Organ Prolapse Indian Medical PG Practice Questions and MCQs
Question 1: Gold standard management for vault prolapse is
- A. Sacrospinous ligament fixation
- B. Sacral colpopexy (Correct Answer)
- C. LeFort repair
- D. Anterior colporrhaphy
Explanation: ***Sacral colpopexy*** - **Sacral colpopexy** is considered the **gold standard** for treating post-hysterectomy vaginal vault prolapse due to its high success rates and durability. - It involves attaching a synthetic mesh from the vaginal apex to the **anterior longitudinal ligament** of the sacrum, effectively suspending the vagina. *Sacrospinous ligament fixation* - While effective for vault prolapse, **sacrospinous ligament fixation** involves unilateral attachment of the vaginal vault to the sacrospinous ligament, which can cause **vaginal axis deviation**. - Its long-term success rates are generally considered slightly lower than sacral colpopexy, although it is still a viable option, especially in cases where an abdominal approach is contraindicated. *LeFort repair* - **LeFort repair** is a **colpocleisis procedure**, meaning it involves partial closure of the vagina, typically reserved for elderly patients who are no longer sexually active and desire a less invasive procedure. - This option is not considered the "best management" in general as it is a **destructive procedure** that restricts future sexual function. *Anterior colporrhaphy* - **Anterior colporrhaphy** is primarily used to repair a **cystocele** (prolapse of the bladder into the vagina) and does not directly address **vaginal vault prolapse**. - While a patient with vault prolapse might also have a cystocele, anterior colporrhaphy alone would not correct the apical support defect.
Question 2: Which structure can be palpated through the anterior wall of the rectum, directly in front of the rectum in the midline, during a rectal examination of a 27-year-old woman?
- A. Bladder
- B. Body of uterus
- C. Cervix of uterus (Correct Answer)
- D. Pubic symphysis
Explanation: Cervix of uterus - The cervix is located posterior to the bladder and inferior to the body of the uterus, making it palpable through the anterior rectal wall via the rectovaginal septum [2]. - Its firm, rounded structure can be felt as a distinct nodule directly anterior to the rectum in the midline during a digital rectal examination. - This is a standard clinical finding in pelvic examination. Bladder - The bladder is anterior to the uterus and cervix; an empty bladder is usually not palpable through the anterior rectal wall. - A distended bladder would be palpable, but it would be a soft, fluctuating mass, not a firm structure like the cervix. Body of uterus - The body of the uterus is superior to the cervix and in the typical anteverted position (normal in ~80% of women), it is angled anteriorly and superiorly, generally beyond the reach of a digital rectal exam for direct palpation through the anterior rectal wall [1]. - In the less common retroverted uterus, the body may be palpable through the posterior fornix of the vagina or through the rectum, but this is not the typical anatomical relationship. Pubic symphysis - The pubic symphysis is a bony joint located at the very anterior aspect of the pelvis, far too anterior and superior to be palpable through the anterior wall of the rectum. - It forms the anterior boundary of the bony pelvis, while the rectum is situated posteriorly within the pelvic cavity.
Question 3: In which condition is a rubber-ring pessary an appropriate management for a woman who is having uterovaginal prolapse?
- A. Early pregnancy
- B. Prolapse associated with carcinoma of cervix
- C. Old age (Correct Answer)
- D. Active reproductive age
Explanation: ***Old age*** - A rubber-ring pessary is an appropriate management option for uterovaginal prolapse in older women, especially those who are **not candidates for surgery** due to comorbidities or personal preference. - The goal is to **alleviate symptoms** and improve quality of life without invasive interventions. *Early pregnancy* - Uterovaginal prolapse can occur in early pregnancy, but a rubber-ring pessary is generally **not the primary treatment** as the condition often improves spontaneously with uterine growth at around 12-14 weeks. - Additionally, pessaries can increase the risk of **vaginal infections and discomfort** during pregnancy. *Prolapse associated with carcinoma of cervix* - If uterovaginal prolapse is associated with carcinoma of the cervix, the **carcinoma needs to be addressed first**, typically through oncological treatment. - A pessary would **mask symptoms** and is not an appropriate treatment for underlying malignancy. *Active reproductive age* - For women in their active reproductive age, especially those desiring future pregnancies, **surgical correction** is often preferred for uterovaginal prolapse. - While pessaries can provide temporary relief, they might not be suitable for long-term management or for women with a **desire for definitive repair**.
Question 4: The most common type of genital prolapse is:
- A. Enterocele
- B. Cystocele (Correct Answer)
- C. Procidentia
- D. Rectocele
Explanation: ***Cystocele*** - A **cystocele** (also known as a bladder prolapse) is the most common type of genital prolapse. - It occurs when the **bladder bulges into the vagina** due to weakened supporting tissues. *Enterocele* - An **enterocele** is the prolapse of the **small intestine into the vagina**, often occurring after a hysterectomy. - While it is a type of prolapse, it is less common than a cystocele. *Procidentia* - **Uterine procidentia** refers to a complete **uterine prolapse** where the entire uterus descends past the vaginal opening. - This is a severe form of prolapse but is less common than a cystocele. *Rectocele* - A **rectocele** occurs when the **rectum bulges into the vagina** due to weakened rectovaginal septum. - Although common, it is still less frequent than a cystocele.
Question 5: Investigation of choice for lumbar prolapsed disc -
- A. CT Scan
- B. Myelogram
- C. X-ray
- D. MRI (Correct Answer)
Explanation: ***MRI*** - An **MRI** provides the best visualization of **soft tissues**, including the intervertebral discs, spinal cord, and nerve roots, making it the **gold standard** for diagnosing lumbar prolapsed disc. - It can accurately show the **degree of disc herniation**, its impact on neural structures, and associated edema, which are crucial for treatment planning. *CT Scan* - While a **CT scan** provides good bony detail and can show disc herniation, its ability to visualize soft tissues is inferior to MRI for this specific condition. - It involves **ionizing radiation** and may miss subtle nerve root compression or spinal cord abnormalities apparent on MRI. *Myelogram* - A **myelogram** involves injecting contrast dye into the spinal canal and then performing X-rays or CT scans to outline the spinal cord and nerve roots. - Though effective in showing **nerve compression**, it is an **invasive procedure** with potential complications and has largely been replaced by MRI as a first-line diagnostic investigation. *X-ray* - **X-rays** primarily visualize **bony structures** and are useful for detecting fractures, spinal alignment issues, or severe degenerative changes. - They **cannot directly visualize intervertebral discs** or nerve compression, making them unsuitable for diagnosing a prolapsed disc.
Question 6: A 60-year-old woman comes with 3rd degree uterine prolapse. What will be the management?
- A. Vaginal hysterectomy with pelvic floor repair (Correct Answer)
- B. Pelvic floor repair
- C. Sacrospinous fixation
- D. Pessary
Explanation: ***Vaginal hysterectomy with pelvic floor repair*** - A **3rd degree uterine prolapse** means the cervix and uterus protrude beyond the introitus, requiring surgical intervention in most cases. - **Vaginal hysterectomy** addresses the prolapsed uterus, and **pelvic floor repair** (e.g., anterior/posterior colporrhaphy) simultaneously reinforces weakened pelvic support structures to prevent recurrence. - This is the **most definitive surgical management** for complete uterine prolapse in a postmenopausal woman. *Pelvic floor repair* - While important for addressing fascial defects, **pelvic floor repair alone** is insufficient for 3rd-degree uterine prolapse where the uterus itself is significantly descended. - This option would leave the **prolapsed uterus** unaddressed, making long-term surgical success unlikely. *Sacrospinous fixation* - **Sacrospinous fixation** is a procedure primarily used for **vaginal vault prolapse** (post-hysterectomy) or as part of apical suspension, by attaching the vaginal apex to the sacrospinous ligament. - While it can be used for **uterine-sparing procedures** (sacrospinous hysteropexy), it is not the primary or sole management when the standard approach is vaginal hysterectomy with repair. *Pessary* - A **pessary** is a non-surgical option appropriate for patients who are **not surgical candidates** (significant comorbidities, elderly frail patients) or those who **decline surgery**. - While it can provide symptomatic relief even for 3rd-degree prolapse, it requires regular follow-up and is generally considered a **conservative/temporizing measure** rather than definitive management when surgery is feasible.
Question 7: A judge can ask clarifying questions when:
- A. At any time during the proceedings (Correct Answer)
- B. Before cross-examination
- C. During witness testimony only
- D. After cross-examination
Explanation: ***At any time during the proceedings*** - A judge's primary role is to ensure **justice** and clarity in the courtroom. Therefore, they are permitted to ask **clarifying questions** at any juncture. - This ensures they understand the evidence, testimony, and arguments presented by all parties for a fair adjudication. *Before cross-examination* - While a judge can ask questions at this stage, limiting it to "before cross-examination" is **too restrictive** and does not accurately reflect their inherent authority throughout a trial. - Their ability to seek clarification is not bound by specific procedural intervals like the start of cross-examination. *During witness testimony only* - This option is **too narrow** as a judge may need to clarify points made during opening statements, closing arguments, or even legal motions, not just during direct or cross-examination of a witness. - Limiting it to witness testimony would **impede their ability** to fully understand all aspects of the case. *After cross exam* - This is also an **incomplete** statement, as waiting until after cross-examination could mean missing opportunities to clarify earlier ambiguities that might affect subsequent testimony or arguments. - A judge's power to clarify is **continuous** and not confined to the end of a specific examination phase.
Question 8: Match the following: A) Caplan syndrome- 1) Found first in coal worker B) Asbestosis- 2) Upper lobe predominance C) Mesothelioma- 3) Involves lower lobe D) Sarcoidosis- 4) Pleural effusion is seen
- A. A-3, B-4, C-2, D-1
- B. A-1, B-4, C-3, D-2 (Correct Answer)
- C. A-4, B-2, C-3, D-1
- D. A-2, B-4, C-3, D-1
Explanation: **A-1, B-4, C-3, D-2** - **Caplan syndrome** was first described in **coal workers** with **rheumatoid arthritis** and progressive massive fibrosis. - **Asbestosis** is often associated with **pleural effusion**, which can be benign or malignant. - **Mesothelioma** typically involves the **lower lobes** of the lungs, specifically the pleura, and is strongly linked to asbestos exposure. - **Sarcoidosis** is characterized by **non-caseating granulomas**, which have a predilection for the **upper lobes** of the lungs. *A-3, B-4, C-2, D-1* - This option incorrectly states that Caplan syndrome involves the lower lobe; **Caplan syndrome** is defined by the presence of large nodules in the lungs of coal workers with rheumatoid arthritis, and their specific lobar distribution is not a defining characteristic. - This option incorrectly states that Mesothelioma has an upper lobe predominance; **Mesothelioma** is a pleural malignancy and typically involves the **lower lobes**, extending along the pleura. *A-4, B-2, C-3, D-1* - This option incorrectly associates Caplan syndrome with pleural effusion; **Caplan syndrome** manifests as rheumatoid nodules in the lungs, not primarily pleural effusion. - This option incorrectly states that Asbestosis has an upper lobe predominance; **Asbestosis** predominantly affects the **lower lobes** of the lungs, causing interstitial fibrosis. *A-2, B-4, C-3, D-1* - This option incorrectly states that Caplan syndrome has an upper lobe predominance; the defining feature of **Caplan syndrome** is the combination of rheumatoid arthritis and pneumoconiosis, not specific lobar involvement. - This option correctly identifies pleural effusion with asbestosis and lower lobe involvement with mesothelioma, but **Caplan syndrome** is not characterized by upper lobe predominance.
Question 9: 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 10: Which of the following is measured without any straining while examination under POP-Q system?
- A. Point D
- B. TVL (Correct Answer)
- C. GH
- D. Pb
Explanation: ***TVL*** - **Total Vaginal Length (TVL)** is the **only measurement** in the POP-Q system that is taken **exclusively at rest without straining**. - It is measured from the **hymen to the posterior fornix** (or vaginal cuff in post-hysterectomy cases) with the patient in supine lithotomy position. - This measurement reflects the overall depth of the vagina and provides important anatomical context for prolapse assessment. *Point D* - **Point D** represents the location of the **posterior fornix** (or vaginal cuff scar in post-hysterectomy). - In the POP-Q system, Point D is measured **both at rest and with maximal straining** to assess the degree of **uterine descent or vaginal vault prolapse**. - The difference between rest and strain measurements helps quantify the extent of apical support defects. *GH* - **Genital Hiatus (GH)** is measured from the **external urethral meatus to the posterior hymen**. - GH is measured **both at rest and during maximal Valsalva straining** in the standard POP-Q protocol. - The measurement increases with straining as pelvic floor muscles relax, reflecting the functional capacity of the pelvic floor. *Pb* - **Perineal Body (Pb)** is measured from the **posterior margin of the genital hiatus to the mid-anal opening**. - Like GH, Pb is measured **both at rest and with straining** in the POP-Q examination. - Changes with straining can indicate perineal descent or posterior compartment defects like rectocele.
