Uterine prolapse occurs when the uterus descends from its normal anatomical position into the vaginal canal, sometimes protruding entirely outside the introitus. This condition arises from the failure of the pelvic floor support structures, which include the levator ani muscle complex, endopelvic fascia, and specific ligaments such as the uterosacral and cardinal ligaments. When these structures are weakened, stretched, or torn, they can no longer maintain the pelvic organs in their proper intra-abdominal positions. As intra-abdominal pressure increases from coughing, lifting, or straining, the unsupported uterus is pushed downward through the path of least resistance, which is the vaginal canal.
Multiple childbirths, particularly unattended or traumatic vaginal deliveries involving prolonged second-stage labor, represent the leading cause of uterine prolapse in Nigerian clinical practice. Other contributing factors include advancing age, chronic constipation, persistent heavy lifting associated with market trading or farming, and chronic respiratory conditions causing recurrent coughing. Postmenopausal estrogen depletion also leads to tissue atrophy and loss of collagen integrity, further compounding the weakness of the pelvic support network.
Patients with uterine prolapse often describe a distinct sensation of a heavy, dragging feeling in the pelvis, frequently reported as "something coming down" or sitting in the vagina. Symptoms typically worsen toward the end of the day after prolonged standing or heavy physical work and improve with lying down. Urinary symptoms such as stress incontinence or incomplete bladder emptying are common, as are bowel elimination difficulties. In severe cases, the protruding cervix and vaginal mucosa can become rubbed against clothing, leading to ulceration, bleeding, and infection.
Clinicians grade uterine prolapse based on how far the cervix or uterus has descended into the vaginal canal.
Diagnosis relies heavily on a thorough pelvic examination performed while the patient is in the lithotomy position. The midwife or doctor asks the patient to bear down or cough to visualize the maximum extent of the organ descent. A speculum examination helps assess the health of the vaginal mucosa and check for any ulcerations caused by friction. In some cases, a multichannel urodynamic study or pelvic ultrasound is performed to evaluate bladder function and rule out other pelvic pathologies.
Management options range from conservative measures to surgical repair, depending on the severity of the prolapse and the patient's age and desire for future fertility. Conservative care includes pelvic floor muscle training (Kegel exercises), lifestyle modifications, and the use of vaginal pessaries to support the uterus. For women with advanced prolapse or those who have completed their families, surgical interventions such as vaginal hysterectomy, pelvic floor reconstruction, or colporrhaphy may be performed. Nursing care centers on patient education, pessary hygiene management, pre- and post-operative care, and providing empathetic emotional support.
Preventing uterine prolapse focuses on reducing known risk factors during pregnancy, labor, and the postpartum period. Midwives play a crucial role by promoting active management of the third stage of labor, avoiding routine or aggressive fundal pressure, and discouraging early heavy lifting after childbirth. Teaching all postnatal women correct pelvic floor exercises and advising on weight management and dietary changes to prevent constipation are vital components of community health education.
