0 min readIntroduction
Uterine prolapse, a common gynecological condition, occurs when the uterus descends from its normal position into the vaginal canal. It arises from weakening of the pelvic floor muscles and supporting ligaments. The severity is graded from 1st to 4th degree, with 3rd degree indicating that the uterus protrudes beyond the vaginal introitus. This condition significantly impacts quality of life, causing symptoms like pelvic pressure, urinary issues, and bowel disturbances. A 42-year-old woman who has completed her family presents a specific scenario where definitive surgical correction is often preferred over conservative management, given the likelihood of recurrence with non-operative approaches.
Aetiology of Uterine Prolapse
Uterine prolapse is multifactorial, with several contributing factors:
- Parity: Multiple vaginal deliveries are a major risk factor, stretching and weakening pelvic floor muscles.
- Age: Age-related decline in estrogen levels leads to atrophy of pelvic floor tissues.
- Obesity: Increased intra-abdominal pressure.
- Chronic Cough: Persistent increase in intra-abdominal pressure (e.g., chronic bronchitis).
- Chronic Constipation: Straining during bowel movements increases intra-abdominal pressure.
- Heavy Lifting: Repeated heavy lifting can strain pelvic floor muscles.
- Genetics: Connective tissue disorders can predispose individuals to prolapse.
- Previous Pelvic Surgery: Hysterectomy or other pelvic surgeries can disrupt supporting structures.
Supports of the Uterus
The uterus is supported by a complex network of structures:
- Pelvic Floor Muscles: Levator ani muscle group (pubococcygeus, puborectalis, iliococcygeus) forms the primary support.
- Urogenital Diaphragm: Provides support to the bladder and urethra, indirectly supporting the uterus.
- Cardinal Ligaments (Broad Ligaments): Attach the cervix and upper vagina to the pelvic sidewalls.
- Uterosacral Ligaments: Attach the cervix to the sacrum.
- Round Ligaments: Attach the uterus to the labia majora, providing anterior support.
These supports work synergistically to maintain uterine position. Weakening of any or all of these structures can lead to prolapse.
Management of 3rd Degree Uterine Prolapse in a 42-Year-Old Woman (Completed Family)
Given the patient’s age and completed family, surgical intervention is generally the preferred approach for a 3rd-degree prolapse. However, a thorough evaluation is crucial.
Assessment
- Detailed History: Symptoms, impact on quality of life, medical comorbidities.
- Physical Examination: Assess the degree of prolapse, vaginal length, and presence of cystocele or rectocele.
- Urodynamic Studies: Evaluate bladder function, especially if urinary symptoms are present.
Management Options
- Conservative Management (Limited Role):
- Pelvic Floor Exercises (Kegel Exercises): Strengthen pelvic floor muscles. Limited efficacy for 3rd-degree prolapse.
- Pessary: A silicone device inserted into the vagina to support the uterus. Can provide temporary relief but requires regular follow-up and is not a definitive solution.
- Surgical Management:
- Vaginal Hysterectomy with Pelvic Floor Repair: Removal of the uterus along with repair of the weakened pelvic floor muscles and supporting ligaments. This is often the preferred option for women who have completed their families.
- Uterine-Sparing Procedures (Sacrospinous Ligament Fixation, Sacrohysteropexy): These procedures aim to suspend the uterus without removing it. Suitable for women who desire to preserve fertility (not applicable in this case).
- Laparoscopic Sacrohysteropexy: Minimally invasive approach to suspend the uterus to the sacrum.
For this patient, vaginal hysterectomy with pelvic floor repair is the most appropriate management option. This provides definitive correction of the prolapse and eliminates the risk of future uterine bleeding. Pre-operative optimization of comorbidities is essential. Post-operative care includes pelvic floor exercises and avoidance of heavy lifting.
Potential Complications of Surgery: Vaginal bleeding, infection, urinary retention, bowel injury, mesh erosion (if mesh is used).
Conclusion
Uterine prolapse is a common condition with significant morbidity. A thorough understanding of its aetiology and supporting structures is crucial for effective management. In a 42-year-old woman who has completed her family, vaginal hysterectomy with pelvic floor repair offers a definitive solution for a 3rd-degree prolapse, improving quality of life and alleviating associated symptoms. Careful patient selection, pre-operative optimization, and meticulous surgical technique are essential for successful outcomes.
